Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers
* upstream: whitespace
OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538
* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.

* upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV
explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

These are now used by sshd_config:ChannelTimeouts to specify timeouts by
channel type, so force them all to use a similar format without whitespace.

"session:subsystem:sftp") that will be used for setting channel inactivity
timeouts.

OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca
* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@
* upstream: Copy bytes from the_banana[] rather than banana()
Fixes test failure due to segfault seen on arm64 with xonly snap.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have
netcat, but now we use our own netcat it tries and fails.
* try to improve logging for dynamic-forward test
previously the logs from the ssh used to exercise the forwarding
channel would clobber the logs from the ssh actually doing the
forwarding

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on
some older platforms.
* remove buffer len workaround for NetBSD 4.x
Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.
* upstream: rewrite this test to use a multiplexed ssh session so we can
control its lifecycle without risk of race conditions; fixes some of the
Github integration tests for openssh-portable

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

this test until we figure out if we can make it work.

../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error

tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers

* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.

* upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV
explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

ssh(1). User authentication keys that fall beneath this limit will be
ignored. If a host presents a host key beneath this limit then the connection
will be terminated (unfortunately there are no fallbacks in the protocol for
host authentication).

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a

OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

* upstream: Add channel_set_xtype()
This sets an "extended" channel type after channel creation (e.g.
"session:subsystem:sftp") that will be used for setting channel inactivity
timeouts.

OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca
* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@
* upstream: Copy bytes from the_banana[] rather than banana()
Fixes test failure due to segfault seen on arm64 with xonly snap.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have
netcat, but now we use our own netcat it tries and fails.
* try to improve logging for dynamic-forward test
previously the logs from the ssh used to exercise the forwarding
channel would clobber the logs from the ssh actually doing the
forwarding

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on
some older platforms.
* remove buffer len workaround for NetBSD 4.x
Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.
* upstream: rewrite this test to use a multiplexed ssh session so we can
control its lifecycle without risk of race conditions; fixes some of the
Github integration tests for openssh-portable

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

be too fragile, we'll see if we need a different approach. The resulting sshd

binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further

* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to

prematurely committed in commit 73541f2.

instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

POSIX doesn't specify the internal layout of the fd_set object, so let's

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync

* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system

it. Prompted by bz#3518.

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

This adds a sshd_config ChannelTimeouts directive that allows channels that

Different timeouts may be applied to session, X11, agent and TCP forwarding

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@
* upstream: Copy bytes from the_banana[] rather than banana()
Fixes test failure due to segfault seen on arm64 with xonly snap.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on

Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.

Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Different timeouts may be applied to session, X11, agent and TCP forwarding

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

netcat, but now we use our own netcat it tries and fails.
* try to improve logging for dynamic-forward test
previously the logs from the ssh used to exercise the forwarding
channel would clobber the logs from the ssh actually doing the
forwarding

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on
some older platforms.
* remove buffer len workaround for NetBSD 4.x
Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.
* upstream: rewrite this test to use a multiplexed ssh session so we can

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.

binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.

* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.

tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

In the case where the previous run did not clean up, the checkout will

* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

* Skip reexec test on OpenSSL 1.1.1 specifically.
OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip
that test. See bz#3483 for details.
* Remove seed passing over reexec.
This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.
ssh-random-helper is long gone, and since the re-exec happens before the
chroot the re-execed sshd can reseed itself normally. ok djm@

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Different timeouts may be applied to session, X11, agent and TCP forwarding

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

original host arg. Inspired by patch from vincent at bernat.ch via bz#3343,

OpenBSD-Commit-ID: 59c0f60a222113a44d0650cd394376e3beecc883
* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.
OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4
* Retry package installation 3 times.
When setting up the CI environment, retry package installation 3 times
before going up. Should help prevent spurious failures during
infrastructure issues.
* upstream: Document "UserKnownHostsFile none". ok djm@
OpenBSD-Commit-ID: f695742d39e34ecdcc3c861c3739a84648a4bce5
* upstream: fix double phrase in previous;
OpenBSD-Commit-ID: 671e6c8dc5e9230518b2bbfa143daaa88adc66c2
* upstream: Instead of skipping the all-tokens test if we don't have
OpenSSL (since we use it to compute the hash), put the hash at the end and
just omit it if we don't have it. Prompted by bz#3521.
OpenBSD-Regress-ID: c79ecba64250ed3b6417294b6c965e6b12ca5eea
* upstream: Shell syntax fix. From ren mingshuai vi github PR#369.
OpenBSD-Regress-ID: 6696b2eeefe128099fc3d7ea9f23252cc35156f9
* Allow writev is seccomp sandbox.
This seems to be used by recent glibcs at least in some configurations.
From bz#3512, ok djm@
* upstream: update OpenSSH's Ed25519 code to the last version of SUPERCOP
(20221122) and change the import approach to the same one we use for
Streamlined NTRUPrime: use a shell script to extract the bits we need from
SUPERCOP, make some minor adjustments and squish them all into a single file.
ok tb@ tobhe@
OpenBSD-Commit-ID: 1bc0fd624cb6af440905b8ba74ac7c03311b8e3b
* upstream: adapt to ed25519 changes in src/usr.bin/ssh
OpenBSD-Regress-ID: 4b3e7ba7ee486ae8a0b4790f8112eded2bb7dcd5
* upstream: Add a sshd_config UnusedConnectionTimeout option to terminate
client connections that have no open channels for some length of time. This
complements the recently-added ChannelTimeout option that terminates inactive
channels after a timeout.
ok markus@
OpenBSD-Commit-ID: ca983be74c0350364c11f8ba3bd692f6f24f5da9
* upstream: unbreak test: cannot access shell positional parameters
past $9 without wrapping the position in braces (i.e. need ${10}, etc.)
OpenBSD-Regress-ID: 3750ec98d5d409ce6a93406fedde6f220d2ea2ac
* upstream: regression test for UnusedConnectionTimeout
OpenBSD-Regress-ID: 7f29001374a68e71e5e078f69e4520cf4bcca084

UnusedConnectionTimeout idea markus@
OpenBSD-Regress-ID: 55c0fb61f3bf9e092b0a53f9041d3d2012f14003
* upstream: For "ssh -V" always exit 0, there is no need to check opt
again. This was missed when the fallthrough in the switch case above it was
removed. OK deraadt@
OpenBSD-Commit-ID: 5583e5d8f6d62a8a4215cfa95a69932f344c8120
* upstream: Add a -V (version) option to sshd like the ssh client
has. OK markus@ deraadt@
OpenBSD-Commit-ID: abe990ec3e636fb040132aab8cbbede98f0c413e
* upstream: when restoring non-blocking mode to stdio fds, restore
exactly the flags that ssh started with and don't just clobber them with
zero, as this could also remove the append flag from the set;
bz3523; ok dtucker@
OpenBSD-Commit-ID: 1336b03e881db7564a4b66014eb24c5230e9a0c0
* Skip connection-timeout when missing FD passing.
This tests uses multiplexing which uses file descriptor passing, so
skip it if we don't have that. Fixes test failures on Cygwin.
* Skip connection-timeout test under Valgrind.
Valgrind slows things down so much that the timeout test fails. Skip
this test until we figure out if we can make it work.
* upstream: tweak previous; ok djm
OpenBSD-Commit-ID: df71ce4180c58202dfdc1d92626cfe900b91b7c3
* upstream: Create and install sshd random relink kit.
../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm
OpenBSD-Commit-ID: 1e0a2692b7e20b126dda60bf04999d1d30d959d8
* upstream: delete useless dependency
OpenBSD-Commit-ID: e1dc11143f83082e3154d6094f9136d0dc2637ad
* fix libfido2 detection without pkg-config
Place libfido2 before additional libraries (that it may depend upon)
and not after. bz3530 from James Zhang; ok dtucker@
* Skip connection-timeout test on minix3.
Minix 3's Unix domain sockets don't seem to work the way we expect, so
skip connection-timeout test on that platform. While there, group
together all similarly skipped tests and explicitly comment.
* upstream: fix double-free caused by compat_kex_proposal(); bz3522
by dtucker@, ok me
OpenBSD-Commit-ID: 2bfc37cd2d41f67dad64c17a64cf2cd3806a5c80
* upstream: openssh-9.2
OpenBSD-Commit-ID: f7389f32413c74d6e2055f05cf65e7082de03923
* upstream: Check if we can copy sshd or need to use sudo to do so
during reexec test. Skip test if neither can work. Patch from anton@, tweaks
from me.

* upstream: test compat_kex_proposal(); by dtucker@
OpenBSD-Regress-ID: 0e404ee264db546f9fdbf53390689ab5f8d38bf2

* fix some failing bash tests
* make bash test compatible with Windows
* address scp's sftp mode buf len limitations

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers
* upstream: whitespace

* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.
* additional keys
* upstream: whitespace
OpenBSD-Commit-ID: c2bcbf93610d3d62ed206cdf9bf9ff98c6aaf232
* Move sftp from valgrind-2 to 3 to rebalance.
* upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV
explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf
Fixes the following build failure with Clang 15 on musl:

Now that all FIDO signing calls attempt first without PIN and then
fall back to trying PIN only if that attempt fails, we can remove the
hack^wtrick that removed the UV flag from the keys returned during
enroll.

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Check for sockaddr_in.sin_len.
If found, set SOCK_HAS_LEN which is used in addr.c. Should fix keyscan
tests on platforms with this (eg old NetBSD).
* Always use compat getentropy.
Have it call native getentropy and fall back as required. Should fix
issues of platforms where libc has getentropy but it is not implemented
in the kernel. Based on github PR#354 from simsergey.
* Include time.h when defining timegm.
Fixes build on some platforms eg recent AIX.
* Compat tests need libcrypto.
This was moved to CHANNELLIBS during the libs refactor. Spotted by
rapier at psc.edu.
* Run compat regress tests too.
* Add tests for OpenSSL 3.0.7 and LibreSSL 3.6.1.
* Only run opensslver tests if built with OpenSSL.
* Increase selfhosted job timeout.
The default job timeout of 360 (6h) is not enough to complete the
regress tests for some of the slow VMs depending on the load on the host.
Increase to 600 (10h).
* Fix compat regress to work with non-GNU make.
* Link libssh into compat tests.
The cygwin compat code uses xmalloc, so add libssh.a so pick up that.
* Rerun tests on changes to Makefile.in in any dir.
* upstream: replace recently-added valid_domain() check for hostnames
going to known_hosts with a more relaxed check for bad characters; previous
commit broke address literals. Reported by/feedback from florian@

* configure.ac: Fix -Wstrict-prototypes
Clang 16 now warns on this and it'll be removed in C23, so let's

* Fix setres*id checks to work with clang-16.
glibc has the prototypes for setresuid and setresgid behind _GNU_SOURCE,

* Split out rekey test since it runs the longest.
* Update checkout and upload actions.
Update actions/checkout and actions/upload-artifact to main branch for
compatibility with node.js v16.
* Add valrind-5 test here too.
* Run vm startup and shutdown from runner temp dir.
Should work even if the github workspace dir is on a stale sshfs mount.
* Shutdown any VM before trying to check out repo.
In the case where the previous run did not clean up, the checkout will
fail as it'll leave a stale mount.
* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

* Skip reexec test on OpenSSL 1.1.1 specifically.
OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip
that test. See bz#3483 for details.
* Remove seed passing over reexec.
This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.
ssh-random-helper is long gone, and since the re-exec happens before the
chroot the re-execed sshd can reseed itself normally. ok djm@

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Different timeouts may be applied to session, X11, agent and TCP forwarding

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers
* upstream: whitespace
OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538
* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.
* additional keys
* upstream: whitespace
OpenBSD-Commit-ID: c2bcbf93610d3d62ed206cdf9bf9ff98c6aaf232
* Move sftp from valgrind-2 to 3 to rebalance.
* upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV
explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf
Fixes the following build failure with Clang 15 on musl:

Now that all FIDO signing calls attempt first without PIN and then
fall back to trying PIN only if that attempt fails, we can remove the
hack^wtrick that removed the UV flag from the keys returned during
enroll.

OpenBSD-Commit-ID: 684517608c8491503bf80cd175425f0178d91d7f
* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with

The assumption is also worthless as we already refuse to use file

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

These are now used by sshd_config:ChannelTimeouts to specify timeouts by
channel type, so force them all to use a similar format without whitespace.

OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65

This sets an "extended" channel type after channel creation (e.g.
"session:subsystem:sftp") that will be used for setting channel inactivity
timeouts.

OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca
* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@
* upstream: Copy bytes from the_banana[] rather than banana()
Fixes test failure due to segfault seen on arm64 with xonly snap.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.
OpenBSD-Regress-ID: 49a375b2cf61ccb95b52e75e2e025cd10988ebb2
* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have
netcat, but now we use our own netcat it tries and fails.
* try to improve logging for dynamic-forward test
previously the logs from the ssh used to exercise the forwarding
channel would clobber the logs from the ssh actually doing the
forwarding

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on
some older platforms.
* remove buffer len workaround for NetBSD 4.x
Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.
* upstream: rewrite this test to use a multiplexed ssh session so we can
control its lifecycle without risk of race conditions; fixes some of the
Github integration tests for openssh-portable

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

This tests uses multiplexing which uses file descriptor passing, so
skip it if we don't have that. Fixes test failures on Cygwin.

this test until we figure out if we can make it work.

../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.

* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.

* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

POSIX doesn't specify the internal layout of the fd_set object, so let's

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

These are now used by sshd_config:ChannelTimeouts to specify timeouts by
channel type, so force them all to use a similar format without whitespace.

This sets an "extended" channel type after channel creation (e.g.
"session:subsystem:sftp") that will be used for setting channel inactivity
timeouts.

OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca
* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further

* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

ssh(1). User authentication keys that fall beneath this limit will be
ignored. If a host presents a host key beneath this limit then the connection
will be terminated (unfortunately there are no fallbacks in the protocol for
host authentication).

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.
ok markus dtucker
OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b
* upstream: tweak channel ctype names
These are now used by sshd_config:ChannelTimeouts to specify timeouts by
channel type, so force them all to use a similar format without whitespace.
ok dtucker markus
OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65
* upstream: Add channel_set_xtype()
This sets an "extended" channel type after channel creation (e.g.
"session:subsystem:sftp") that will be used for setting channel inactivity
timeouts.
ok markus dtucker
OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca
* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@
* upstream: Copy bytes from the_banana[] rather than banana()
Fixes test failure due to segfault seen on arm64 with xonly snap.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.
OpenBSD-Regress-ID: 49a375b2cf61ccb95b52e75e2e025cd10988ebb2
* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have
netcat, but now we use our own netcat it tries and fails.
* try to improve logging for dynamic-forward test
previously the logs from the ssh used to exercise the forwarding
channel would clobber the logs from the ssh actually doing the
forwarding
* upstream: tweak previous; ok djm

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

OpenBSD-Commit-ID: b80c372faac462471e955ddeab9480d668a2e48d
* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on
some older platforms.
* remove buffer len workaround for NetBSD 4.x
Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.
* upstream: rewrite this test to use a multiplexed ssh session so we can
control its lifecycle without risk of race conditions; fixes some of the
Github integration tests for openssh-portable
OpenBSD-Regress-ID: 5451cad59ba0d43ae9eeda48ec80f54405fee969

OpenBSD-Commit-ID: 59c0f60a222113a44d0650cd394376e3beecc883
* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.
OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4
* Retry package installation 3 times.
When setting up the CI environment, retry package installation 3 times

just omit it if we don't have it. Prompted by bz#3521.

* Skip connection-timeout when missing FD passing.
This tests uses multiplexing which uses file descriptor passing, so
skip it if we don't have that. Fixes test failures on Cygwin.
* Skip connection-timeout test under Valgrind.
Valgrind slows things down so much that the timeout test fails. Skip
this test until we figure out if we can make it work.

OpenBSD-Commit-ID: df71ce4180c58202dfdc1d92626cfe900b91b7c3
* upstream: Create and install sshd random relink kit.
../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm

Minix 3's Unix domain sockets don't seem to work the way we expect, so

* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.

explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: remove '?' from getopt(3) loops
userspace: remove vestigial '?' cases from top-level getopt(3) loops
getopt(3) returns '?' when it encounters a flag not present in the in
the optstring or if a flag is missing its option argument. We can
handle this case with the "default" failure case with no loss of
legibility. Hence, remove all the redundant "case '?':" lines.

* upstream: The idiomatic way of coping with signed char vs unsigned
char (which did not come from stdio read functions) in the presence of
ctype macros, is to always cast to (unsigned char). casting to (int)
for a "macro" which is documented to take int, is weird. And sadly wrong,
because of the sing extension risk.. same diff from florian

* upstream: add a -X option to both scp(1) and sftp(1) to allow
control over some SFTP protocol knobs: the copy buffer length and
the number of inflight requests, both of which are used during
upload/download.
Previously these could be controlled in sftp(1) using the -b/-R options.
This makes them available in both SFTP protocol clients using the same
option character sequence.

* upstream: Clear signal mask early in main(); sshd may have been
started with one or more signals masked (sigprocmask(2) is not cleared
on fork/exec) and this could interfere with various things, e.g. the
login grace timer.
Execution environments that fail to clear the signal mask before running
sshd are clearly broken, but apparently they do exist.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to

This puts back the original 32KB copy buffer size until we can properly
figure out why.

* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers
* upstream: whitespace
OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538
* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.
* additional keys
* upstream: whitespace
OpenBSD-Commit-ID: c2bcbf93610d3d62ed206cdf9bf9ff98c6aaf232
* Move sftp from valgrind-2 to 3 to rebalance.
* upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV
explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf
Fixes the following build failure with Clang 15 on musl:

Now that all FIDO signing calls attempt first without PIN and then
fall back to trying PIN only if that attempt fails, we can remove the
hack^wtrick that removed the UV flag from the keys returned during
enroll.

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip

This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

the connection itself. Most clients close the connection when their channels

* upstream: Instead of skipping the all-tokens test if we don't have
OpenSSL (since we use it to compute the hash), put the hash at the end and
just omit it if we don't have it. Prompted by bz#3521.
OpenBSD-Regress-ID: c79ecba64250ed3b6417294b6c965e6b12ca5eea

* Allow writev is seccomp sandbox.
This seems to be used by recent glibcs at least in some configurations.
From bz#3512, ok djm@
* upstream: update OpenSSH's Ed25519 code to the last version of SUPERCOP
(20221122) and change the import approach to the same one we use for
Streamlined NTRUPrime: use a shell script to extract the bits we need from
SUPERCOP, make some minor adjustments and squish them all into a single file.

* upstream: Add a sshd_config UnusedConnectionTimeout option to terminate
client connections that have no open channels for some length of time. This
complements the recently-added ChannelTimeout option that terminates inactive
channels after a timeout.

exactly the flags that ssh started with and don't just clobber them with
zero, as this could also remove the append flag from the set;

OpenBSD-Commit-ID: 1336b03e881db7564a4b66014eb24c5230e9a0c0
* Skip connection-timeout when missing FD passing.
This tests uses multiplexing which uses file descriptor passing, so
skip it if we don't have that. Fixes test failures on Cygwin.
* Skip connection-timeout test under Valgrind.
Valgrind slows things down so much that the timeout test fails. Skip
this test until we figure out if we can make it work.
* upstream: tweak previous; ok djm

* upstream: Create and install sshd random relink kit.
../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm

Place libfido2 before additional libraries (that it may depend upon)
and not after. bz3530 from James Zhang; ok dtucker@

Minix 3's Unix domain sockets don't seem to work the way we expect, so
skip connection-timeout test on that platform. While there, group

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers
* upstream: whitespace
OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538
* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.

* upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV
explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf

Now that all FIDO signing calls attempt first without PIN and then
fall back to trying PIN only if that attempt fails, we can remove the
hack^wtrick that removed the UV flag from the keys returned during
enroll.

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

* upstream: Add channel_set_xtype()
This sets an "extended" channel type after channel creation (e.g.
"session:subsystem:sftp") that will be used for setting channel inactivity
timeouts.

OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca
* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@
* upstream: Copy bytes from the_banana[] rather than banana()
Fixes test failure due to segfault seen on arm64 with xonly snap.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have
netcat, but now we use our own netcat it tries and fails.
* try to improve logging for dynamic-forward test
previously the logs from the ssh used to exercise the forwarding
channel would clobber the logs from the ssh actually doing the
forwarding

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on
some older platforms.
* remove buffer len workaround for NetBSD 4.x
Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.
* upstream: rewrite this test to use a multiplexed ssh session so we can
control its lifecycle without risk of race conditions; fixes some of the
Github integration tests for openssh-portable

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further

* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to

* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,

If user entered a non-existent command (e.g. because they made a

From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

* Skip reexec test on OpenSSL 1.1.1 specifically.
OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip
that test. See bz#3483 for details.
* Remove seed passing over reexec.
This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.
ssh-random-helper is long gone, and since the re-exec happens before the
chroot the re-execed sshd can reseed itself normally. ok djm@

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b
* upstream: tweak channel ctype names
These are now used by sshd_config:ChannelTimeouts to specify timeouts by
channel type, so force them all to use a similar format without whitespace.

OpenBSD-Commit-ID: 66834765bb4ae14f96d2bb981ac98a7dae361b65
* upstream: Add channel_set_xtype()
This sets an "extended" channel type after channel creation (e.g.
"session:subsystem:sftp") that will be used for setting channel inactivity
timeouts.

OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca
* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@
* upstream: Copy bytes from the_banana[] rather than banana()
Fixes test failure due to segfault seen on arm64 with xonly snap.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.
OpenBSD-Regress-ID: 49a375b2cf61ccb95b52e75e2e025cd10988ebb2
* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have
netcat, but now we use our own netcat it tries and fails.
* try to improve logging for dynamic-forward test
previously the logs from the ssh used to exercise the forwarding
channel would clobber the logs from the ssh actually doing the
forwarding

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on
some older platforms.
* remove buffer len workaround for NetBSD 4.x
Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.
* upstream: rewrite this test to use a multiplexed ssh session so we can
control its lifecycle without risk of race conditions; fixes some of the
Github integration tests for openssh-portable

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

This tests uses multiplexing which uses file descriptor passing, so
skip it if we don't have that. Fixes test failures on Cygwin.

this test until we figure out if we can make it work.

* upstream: Create and install sshd random relink kit.
../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers
* upstream: whitespace
OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538
* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.

tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf

Now that all FIDO signing calls attempt first without PIN and then
fall back to trying PIN only if that attempt fails, we can remove the
hack^wtrick that removed the UV flag from the keys returned during

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Clear signal mask early in main(); sshd may have been
started with one or more signals masked (sigprocmask(2) is not cleared
on fork/exec) and this could interfere with various things, e.g. the
login grace timer.
Execution environments that fail to clear the signal mask before running
sshd are clearly broken, but apparently they do exist.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

OpenBSD-Commit-ID: 23052707a42bdc62fda2508636e624afd466324b

These are now used by sshd_config:ChannelTimeouts to specify timeouts by
channel type, so force them all to use a similar format without whitespace.

"session:subsystem:sftp") that will be used for setting channel inactivity
timeouts.

OpenBSD-Commit-ID: 42564aa92345045b4a74300528f960416a15d4ca
* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@
* upstream: Copy bytes from the_banana[] rather than banana()
Fixes test failure due to segfault seen on arm64 with xonly snap.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.
OpenBSD-Regress-ID: 49a375b2cf61ccb95b52e75e2e025cd10988ebb2
* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have
netcat, but now we use our own netcat it tries and fails.
* try to improve logging for dynamic-forward test
previously the logs from the ssh used to exercise the forwarding
channel would clobber the logs from the ssh actually doing the
forwarding

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on
some older platforms.
* remove buffer len workaround for NetBSD 4.x
Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.
* upstream: rewrite this test to use a multiplexed ssh session so we can
control its lifecycle without risk of race conditions; fixes some of the
Github integration tests for openssh-portable

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

skip it if we don't have that. Fixes test failures on Cygwin.

Valgrind slows things down so much that the timeout test fails. Skip
this test until we figure out if we can make it work.

* upstream: Create and install sshd random relink kit.
../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm

Merge 9.1 (#626)
* upstream: fix poll() spin when a channel's output fd closes without
data in the channel buffer. Introduce more exact packing of channel fds into
the pollfd array. fixes bz3405 and bz3411; ok deraadt@ markus@
OpenBSD-Commit-ID: 06740737849c9047785622ad5d472cb6a3907d10

sntrup761x25519-sha512@openssh.com as the default; ok markus@
OpenBSD-Commit-ID: f02d99cbfce22dffec2e2ab1b60905fbddf48fb9
* upstream: add support for the "corp-data" protocol extension to
allow server-side copies to be performed without having to go via the client.

* Skip slow tests on (very) slow test targets.
* Set Makefile SHELL as determined by configure.
This should improve compatibility for users with non-POSIX shells. If
using Makefile.in directly (eg make -f Makefile.in distprep) then SHELL
will need to be specified on the command line (along with MANFMT in that
particular case). ok djm@
* Use bash or ksh if available for SH in Makefile.
* Increase test timeout to allow slow VMs to finish
* Only run regression tests on slow VMs.
* Only return events from ppoll that were requested.
If the underlying system's select() returns bits that were not in the
request set, our ppoll() implementation can return revents for events
not requested, which can apparently cause a hang. Only return revents
for activity in the requested event set. bz#3416, analysis and fix by
yaroslav.kuzmin at vmssoftware com, ok djm@
* Specify TEST_SHELL=bash on AIX.
The system shells cause the agent-restrict test to fail due to some
quoting so explicitly specify bash until we can get configure to
autmatically work around that.
* Disable security key on fbsd6 test host.
* upstream: man pages: add missing commas between subordinate and
main clauses
jmc@ dislikes a comma before "then" in a conditional, so leave those
untouched.

* update version numbers for release
* update build-aux files to match autoconf-2.71
i.e. config.guess, config.sub and install-sh
* Revert "update build-aux files to match autoconf-2.71"
This reverts commit 0a8ca39fac6ad19096b6c263436f8b2dd51606f2.
It turns out that the checked-in copies of these files are actually newer
than autoconf-2.71's copies, so this was effectively a downgrade.
Spotted by Bo Anderson via github
* upstream: two defensive changes from Tobias Stoeckmann via GHPR287
enforce stricter invarient for sshbuf_set_parent() - never allow
a buffer to have a previously-set parent changed.
In sshbuf_reset(), if the reallocation fails, then zero the entire
buffer and not the (potentially smaller) default initial alloc size.

Since we no longer need to support SSH1 we don't need to run shell

trade-offs of resident keys. While here, consistently refer to the FIDO

* Add ubsan minimal testcase on OpenBSD.

* Note that, for now, we need variadic macros.
* Also retest OpenBSD upstream on .yml changes.
* upstream: When performing operations that glob(3) a remote path, ensure
that the implicit working directory used to construct that path escapes
glob(3) characters.
This prevents glob characters from being processed in places they
shouldn't, e.g. "cd /tmp/a*/", "get *.txt" should have the get operation
treat the path "/tmp/a*" literally and not attempt to expand it.

* Refuse to use OpenSSL 3.0.4 due to potential RCE.

The potential RCE only impacts x86_64, so only refuse to use it if we're
targetting a potentially impacted architecture. ok djm@
* Remove special casing of crypt().
Configure goes to some lengths to pick crypt() from either libcrypt
or OpenSSL's libcrypto because they can more or less featureful (eg
supporting md5-style passwords).
OpenSSL removed its crypt() interface in 2002:
https://github.com/openssl/openssl/commit/69deec58 so these hijinks
should no longer be necessary. This also only links sshd with libcrypt
which is the only thing that needs it. ok djm@
* Clarify README.md text.
Clarify the text about the implications of building without OpenSSL, and
prefix the "configure --help" example command with a "./" so it's likely
to work as-is in more shells. From bz#3461.
* Split README.platform into its own line.
README.platform has general platform-specific information, having it
following text about FIDO2 on the same line could imply that it only
has information about FIDO2.
* Return ERANGE from getcwd() if buffer size is 1.
If getcwd() is supplied a buffer size of exactly 1 and a path of "/", it
could result in a nul byte being written out of array bounds. POSIX says
it should return ERANGE if the path will not fit in the available buffer
(with terminating nul). 1 byte cannot fit any possible path with its nul,
so immediately return ERANGE in that case.
OpenSSH never uses getcwd() with this buffer size, and all current
(and even quite old) platforms that we are currently known to work
on have a native getcwd() so this code is not used on those anyway.

* Do not link scp, sftp and sftp-server w/ zlib.
Some of our binaries (eg sftp, sftp-server, scp) do not interact with
the channels code and thus do use libraries such as zlib and libcrypto

Since arc4random seeds from getentropy, and we use OpenSSL for that
if enabled, there's the possibility that if we build on a system that
does not have getentropy then run on a system that does have it, then
OpenSSL could end up calling our getentropy and getting stuck in a loop.

non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Split out rekey test since it runs the longest.
* Update checkout and upload actions.
Update actions/checkout and actions/upload-artifact to main branch for
compatibility with node.js v16.
* Add valrind-5 test here too.
* Run vm startup and shutdown from runner temp dir.
Should work even if the github workspace dir is on a stale sshfs mount.
* Shutdown any VM before trying to check out repo.
In the case where the previous run did not clean up, the checkout will
fail as it'll leave a stale mount.
* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

* Skip reexec test on OpenSSL 1.1.1 specifically.
OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip
that test. See bz#3483 for details.
* Remove seed passing over reexec.
This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.
ssh-random-helper is long gone, and since the re-exec happens before the
chroot the re-execed sshd can reseed itself normally. ok djm@

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

OpenBSD-Commit-ID: e1dc11143f83082e3154d6094f9136d0dc2637ad
* fix libfido2 detection without pkg-config
Place libfido2 before additional libraries (that it may depend upon)
and not after. bz3530 from James Zhang; ok dtucker@
* Skip connection-timeout test on minix3.
Minix 3's Unix domain sockets don't seem to work the way we expect, so
skip connection-timeout test on that platform. While there, group
together all similarly skipped tests and explicitly comment.
* upstream: fix double-free caused by compat_kex_proposal(); bz3522
by dtucker@, ok me
OpenBSD-Commit-ID: 2bfc37cd2d41f67dad64c17a64cf2cd3806a5c80
* upstream: openssh-9.2
OpenBSD-Commit-ID: f7389f32413c74d6e2055f05cf65e7082de03923
* upstream: Check if we can copy sshd or need to use sudo to do so
during reexec test. Skip test if neither can work. Patch from anton@, tweaks
from me.
OpenBSD-Regress-ID: 731b96ae74d02d5744e1f1a8e51d09877ffd9b6d
* upstream: test compat_kex_proposal(); by dtucker@

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers
* upstream: whitespace
OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538
* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.
* additional keys
* upstream: whitespace
OpenBSD-Commit-ID: c2bcbf93610d3d62ed206cdf9bf9ff98c6aaf232
* Move sftp from valgrind-2 to 3 to rebalance.
* upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV
explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf
Fixes the following build failure with Clang 15 on musl:

hack^wtrick that removed the UV flag from the keys returned during
enroll.

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

tests on platforms with this (eg old NetBSD).
* Always use compat getentropy.
Have it call native getentropy and fall back as required. Should fix
issues of platforms where libc has getentropy but it is not implemented
in the kernel. Based on github PR#354 from simsergey.
* Include time.h when defining timegm.
Fixes build on some platforms eg recent AIX.
* Compat tests need libcrypto.
This was moved to CHANNELLIBS during the libs refactor. Spotted by
rapier at psc.edu.
* Run compat regress tests too.
* Add tests for OpenSSL 3.0.7 and LibreSSL 3.6.1.
* Only run opensslver tests if built with OpenSSL.
* Increase selfhosted job timeout.
The default job timeout of 360 (6h) is not enough to complete the
regress tests for some of the slow VMs depending on the load on the host.
Increase to 600 (10h).
* Fix compat regress to work with non-GNU make.
* Link libssh into compat tests.
The cygwin compat code uses xmalloc, so add libssh.a so pick up that.
* Rerun tests on changes to Makefile.in in any dir.
* upstream: replace recently-added valid_domain() check for hostnames

Add "compat-tests" to the default TEST_TARGET so we can override as
necessary. Override TEST_TARGET for Cygwin as the tests don't currently
compile there.
* Fix broken zlib link.
* configure.ac: Add <pty.h> include for openpty
Another Clang 16ish fix (which makes -Wimplicit-function-declaration
an error by default). github PR#355.

* configure.ac: Fix -Wstrict-prototypes
Clang 16 now warns on this and it'll be removed in C23, so let's
just be future proof. It also reduces noise when doing general
Clang 16 porting work (which is a big job as it is). github PR#355.

* Fix setres*id checks to work with clang-16.
glibc has the prototypes for setresuid and setresgid behind _GNU_SOURCE,
and clang 16 will error out on implicit function definitions, so add
_GNU_SOURCE and the required headers to the configure checks. From

compatibility with node.js v16.
* Add valrind-5 test here too.
* Run vm startup and shutdown from runner temp dir.

* Shutdown any VM before trying to check out repo.
In the case where the previous run did not clean up, the checkout will

* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

* Skip reexec test on OpenSSL 1.1.1 specifically.
OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip
that test. See bz#3483 for details.
* Remove seed passing over reexec.
This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.
ssh-random-helper is long gone, and since the re-exec happens before the
chroot the re-execed sshd can reseed itself normally. ok djm@

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

OpenBSD-Commit-ID: 1336b03e881db7564a4b66014eb24c5230e9a0c0
* Skip connection-timeout when missing FD passing.
This tests uses multiplexing which uses file descriptor passing, so
skip it if we don't have that. Fixes test failures on Cygwin.
* Skip connection-timeout test under Valgrind.
Valgrind slows things down so much that the timeout test fails. Skip
this test until we figure out if we can make it work.
* upstream: tweak previous; ok djm

* upstream: Create and install sshd random relink kit.
../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm

Place libfido2 before additional libraries (that it may depend upon)
and not after. bz3530 from James Zhang; ok dtucker@
* Skip connection-timeout test on minix3.
Minix 3's Unix domain sockets don't seem to work the way we expect, so
skip connection-timeout test on that platform. While there, group
together all similarly skipped tests and explicitly comment.

* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* unbreak scp on NetBSD 4.x
e555d5cad5 effectively increased the default copy buffer size for SFTP
transfers. This caused NetBSD 4.x to hang during the "copy local file to
remote file in place" scp.sh regression test.
This puts back the original 32KB copy buffer size until we can properly
figure out why.
lots of debugging assistance from dtucker@
* upstream: Copy bytes from the_banana[] rather than banana()
Fixes test failure due to segfault seen on arm64 with xonly snap.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync

* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with

The assumption is also worthless as we already refuse to use file

OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip

* Remove seed passing over reexec.
This was added for the benefit of platforms using ssh-rand-helper to

chroot the re-execed sshd can reseed itself normally. ok djm@

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Different timeouts may be applied to session, X11, agent and TCP forwarding

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* Set OPENSSL_BIN from OpenSSL directory.
* Check openssl_bin path is executable before using.
* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have
netcat, but now we use our own netcat it tries and fails.

* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers

OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538
* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.

tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

This was added for the benefit of platforms using ssh-rand-helper to

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Different timeouts may be applied to session, X11, agent and TCP forwarding

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.
OpenBSD-Regress-ID: 49a375b2cf61ccb95b52e75e2e025cd10988ebb2
* don't test IPv6 addresses if platform lacks support
* Skip dynamic-forward test on minix3.
This test relies on loopback addresses which minix does not have.
Previously the test would not run at all since it also doesn't have
netcat, but now we use our own netcat it tries and fails.
* try to improve logging for dynamic-forward test
previously the logs from the ssh used to exercise the forwarding
channel would clobber the logs from the ssh actually doing the
forwarding

* upstream: Switch scp from using pipes to a socketpair for
communication with it's ssh sub-processes. We no longer need to reserve two
descriptors to ensure that we don't end up using fd 0-2 unexpectedly, that is
handled by sanitise_stdfd() in main(). Based on an original diff from djm@.

* add back use of pipes in scp.c under USE_PIPES
This matches sftp.c which prefers socketpair but uses pipes on
some older platforms.
* remove buffer len workaround for NetBSD 4.x
Switching to from pipes to a socketpair for communicating with the
ssh process avoids the (kernel bug?) problem.
* upstream: rewrite this test to use a multiplexed ssh session so we can
control its lifecycle without risk of race conditions; fixes some of the
Github integration tests for openssh-portable

OpenBSD-Commit-ID: 59c0f60a222113a44d0650cd394376e3beecc883
* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.

* Skip connection-timeout when missing FD passing.
This tests uses multiplexing which uses file descriptor passing, so
skip it if we don't have that. Fixes test failures on Cygwin.

this test until we figure out if we can make it work.

../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.
* initial list of allowed signers
* upstream: whitespace
OpenBSD-Commit-ID: d297e4387935d4aef091c5e9432578c2e513f538
* upstream: whitespace
OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.
* additional keys

OpenBSD-Commit-ID: c2bcbf93610d3d62ed206cdf9bf9ff98c6aaf232
* Move sftp from valgrind-2 to 3 to rebalance.
* upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV
explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip

* Remove seed passing over reexec.
This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.
ssh-random-helper is long gone, and since the re-exec happens before the
chroot the re-execed sshd can reseed itself normally. ok djm@

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Different timeouts may be applied to session, X11, agent and TCP forwarding

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

OpenBSD-Commit-ID: c4965f62fa0ba850940fd66ae3f60cf516bbcd56
* upstream: avoid printf("%s", NULL) if using ssh
-oUserKnownHostsFile=none and a hostkey in one of the system known hosts file
changes; ok dtucker@
OpenBSD-Commit-ID: 7ca87614bfc6da491315536a7f2301434a9fe614
* upstream: Add a "Host" line to the output of ssh -G showing the
original host arg. Inspired by patch from vincent at bernat.ch via bz#3343,
ok djm@
OpenBSD-Commit-ID: 59c0f60a222113a44d0650cd394376e3beecc883
* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.
OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4
* Retry package installation 3 times.
When setting up the CI environment, retry package installation 3 times
before going up. Should help prevent spurious failures during
infrastructure issues.
* upstream: Document "UserKnownHostsFile none". ok djm@
OpenBSD-Commit-ID: f695742d39e34ecdcc3c861c3739a84648a4bce5
* upstream: fix double phrase in previous;
OpenBSD-Commit-ID: 671e6c8dc5e9230518b2bbfa143daaa88adc66c2
* upstream: Instead of skipping the all-tokens test if we don't have
OpenSSL (since we use it to compute the hash), put the hash at the end and
just omit it if we don't have it. Prompted by bz#3521.
OpenBSD-Regress-ID: c79ecba64250ed3b6417294b6c965e6b12ca5eea
* upstream: Shell syntax fix. From ren mingshuai vi github PR#369.
OpenBSD-Regress-ID: 6696b2eeefe128099fc3d7ea9f23252cc35156f9
* Allow writev is seccomp sandbox.
This seems to be used by recent glibcs at least in some configurations.
From bz#3512, ok djm@
* upstream: update OpenSSH's Ed25519 code to the last version of SUPERCOP
(20221122) and change the import approach to the same one we use for
Streamlined NTRUPrime: use a shell script to extract the bits we need from
SUPERCOP, make some minor adjustments and squish them all into a single file.
ok tb@ tobhe@
OpenBSD-Commit-ID: 1bc0fd624cb6af440905b8ba74ac7c03311b8e3b
* upstream: adapt to ed25519 changes in src/usr.bin/ssh
OpenBSD-Regress-ID: 4b3e7ba7ee486ae8a0b4790f8112eded2bb7dcd5
* upstream: Add a sshd_config UnusedConnectionTimeout option to terminate
client connections that have no open channels for some length of time. This
complements the recently-added ChannelTimeout option that terminates inactive
channels after a timeout.
ok markus@
OpenBSD-Commit-ID: ca983be74c0350364c11f8ba3bd692f6f24f5da9
* upstream: unbreak test: cannot access shell positional parameters
past $9 without wrapping the position in braces (i.e. need ${10}, etc.)
OpenBSD-Regress-ID: 3750ec98d5d409ce6a93406fedde6f220d2ea2ac
* upstream: regression test for UnusedConnectionTimeout
OpenBSD-Regress-ID: 7f29001374a68e71e5e078f69e4520cf4bcca084

UnusedConnectionTimeout idea markus@
OpenBSD-Regress-ID: 55c0fb61f3bf9e092b0a53f9041d3d2012f14003
* upstream: For "ssh -V" always exit 0, there is no need to check opt
again. This was missed when the fallthrough in the switch case above it was
removed. OK deraadt@
OpenBSD-Commit-ID: 5583e5d8f6d62a8a4215cfa95a69932f344c8120
* upstream: Add a -V (version) option to sshd like the ssh client
has. OK markus@ deraadt@
OpenBSD-Commit-ID: abe990ec3e636fb040132aab8cbbede98f0c413e
* upstream: when restoring non-blocking mode to stdio fds, restore
exactly the flags that ssh started with and don't just clobber them with
zero, as this could also remove the append flag from the set;
bz3523; ok dtucker@
OpenBSD-Commit-ID: 1336b03e881db7564a4b66014eb24c5230e9a0c0
* Skip connection-timeout when missing FD passing.
This tests uses multiplexing which uses file descriptor passing, so
skip it if we don't have that. Fixes test failures on Cygwin.
* Skip connection-timeout test under Valgrind.
Valgrind slows things down so much that the timeout test fails. Skip
this test until we figure out if we can make it work.
* upstream: tweak previous; ok djm
OpenBSD-Commit-ID: df71ce4180c58202dfdc1d92626cfe900b91b7c3
* upstream: Create and install sshd random relink kit.
../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm
OpenBSD-Commit-ID: 1e0a2692b7e20b126dda60bf04999d1d30d959d8
* upstream: delete useless dependency
OpenBSD-Commit-ID: e1dc11143f83082e3154d6094f9136d0dc2637ad
* fix libfido2 detection without pkg-config
Place libfido2 before additional libraries (that it may depend upon)
and not after. bz3530 from James Zhang; ok dtucker@
* Skip connection-timeout test on minix3.
Minix 3's Unix domain sockets don't seem to work the way we expect, so
skip connection-timeout test on that platform. While there, group
together all similarly skipped tests and explicitly comment.
* upstream: fix double-free caused by compat_kex_proposal(); bz3522
by dtucker@, ok me
OpenBSD-Commit-ID: 2bfc37cd2d41f67dad64c17a64cf2cd3806a5c80
* upstream: openssh-9.2
OpenBSD-Commit-ID: f7389f32413c74d6e2055f05cf65e7082de03923
* upstream: Check if we can copy sshd or need to use sudo to do so
during reexec test. Skip test if neither can work. Patch from anton@, tweaks
from me.
OpenBSD-Regress-ID: 731b96ae74d02d5744e1f1a8e51d09877ffd9b6d
* upstream: test compat_kex_proposal(); by dtucker@
OpenBSD-Regress-ID: 0e404ee264db546f9fdbf53390689ab5f8d38bf2
* adapt compat_kex_proposal() test to portable
* update version in README
* crank versions in RPM specs
* remove files from libssh project
* re-merge arc4random.c
* re-merge misc.c
* remove unused files from libssh.vcxproj
* fix outstanding merge conflicts
* fix build errors
* modify upstream workflows to trigger on workflow dispatch instead of all PRs
* fix scp client hanging with pipes
* fix some failing bash tests
* make bash test compatible with Windows
* address scp's sftp mode buf len limitations
* address review feedback
* address review feedback
* update comment

* upstream: attemp FIDO key signing without PIN and use the error

* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.

Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.

* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

fail as it'll leave a stale mount.
* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip

This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.
ssh-random-helper is long gone, and since the re-exec happens before the
chroot the re-execed sshd can reseed itself normally. ok djm@

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Different timeouts may be applied to session, X11, agent and TCP forwarding

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

Merge 9.2 (#657)
* upstream: attemp FIDO key signing without PIN and use the error
code returned to fall back only if necessary. Avoids PIN prompts for FIDO
tokens that don't require them; part of GHPR#302
OpenBSD-Commit-ID: 4f752aaf9f2e7c28bcaaf3d4f8fc290131bd038e
* Install Cygwin packages based on OS not config.

OpenBSD-Commit-ID: a5d015efbfd228dc598ffdef612d2da3a579e5d8
* Add cygwin-release test target.
This also moves the cygwin package install from the workflow file to
setup_ci.sh so that we can install different sets of Cygwin packages
for different test configs.
* Add Windows 2022 test targets.
* Add libcrypt-devel to cygwin-release deps.
Based on feedback from vinschen at redhat.com.
* cross-sign allowed_signers with PGP key
Provides continuity of trust from legacy PGP release key to
the SSHSIG signing keys that we will use henceforth for git
signing.
* additional keys

OpenBSD-Commit-ID: c2bcbf93610d3d62ed206cdf9bf9ff98c6aaf232
* Move sftp from valgrind-2 to 3 to rebalance.
* upstream: sk-usbhid: fix key_lookup() on tokens with built-in UV
explicitly test whether the token performs built-in UV (e.g. biometric
tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388
OpenBSD-Commit-ID: 007eb7e387d27cf3029ab06b88224e03eca62ccd
* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,
as prompted by logan at cyberstorm.mu in bz#3467. It brings the
platform-specific hooks from LibreSSL Portable, simplified to match our
use case. ok djm@.
* Remove DEF_WEAK, it's already in defines.h.
* openbsd-compat/bsd-asprintf: add <stdio.h> include for vsnprintf
Fixes the following build failure with Clang 15 on musl:

Now that all FIDO signing calls attempt first without PIN and then
fall back to trying PIN only if that attempt fails, we can remove the
hack^wtrick that removed the UV flag from the keys returned during
enroll.

* upstream: sftp: Don't attempt to complete arguments for
non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Check for sockaddr_in.sin_len.
If found, set SOCK_HAS_LEN which is used in addr.c. Should fix keyscan
tests on platforms with this (eg old NetBSD).
* Always use compat getentropy.
Have it call native getentropy and fall back as required. Should fix
issues of platforms where libc has getentropy but it is not implemented
in the kernel. Based on github PR#354 from simsergey.
* Include time.h when defining timegm.
Fixes build on some platforms eg recent AIX.
* Compat tests need libcrypto.
This was moved to CHANNELLIBS during the libs refactor. Spotted by
rapier at psc.edu.
* Run compat regress tests too.
* Add tests for OpenSSL 3.0.7 and LibreSSL 3.6.1.
* Only run opensslver tests if built with OpenSSL.
* Increase selfhosted job timeout.
The default job timeout of 360 (6h) is not enough to complete the
regress tests for some of the slow VMs depending on the load on the host.
Increase to 600 (10h).
* Fix compat regress to work with non-GNU make.
* Link libssh into compat tests.
The cygwin compat code uses xmalloc, so add libssh.a so pick up that.
* Rerun tests on changes to Makefile.in in any dir.
* upstream: replace recently-added valid_domain() check for hostnames
going to known_hosts with a more relaxed check for bad characters; previous
commit broke address literals. Reported by/feedback from florian@

* configure.ac: Fix -Wstrict-prototypes
Clang 16 now warns on this and it'll be removed in C23, so let's

* Fix setres*id checks to work with clang-16.
glibc has the prototypes for setresuid and setresgid behind _GNU_SOURCE,

* Shutdown any VM before trying to check out repo.
In the case where the previous run did not clean up, the checkout will

* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip

* Remove seed passing over reexec.
This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.
ssh-random-helper is long gone, and since the re-exec happens before the
chroot the re-execed sshd can reseed itself normally. ok djm@

autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

control over some SFTP protocol knobs: the copy buffer length and

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

It's possible to install an OpenSSL in a path not in the system's

available on the system path just use that.

* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: add a -X option to both scp(1) and sftp(1) to allow
control over some SFTP protocol knobs: the copy buffer length and
the number of inflight requests, both of which are used during

sshd are clearly broken, but apparently they do exist.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's
default library search path. OpenSSH can still use this (eg if you
specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to
second-guess the behaviour of various netcat implementations.
* upstream: When OpenSSL is not available, skip parts of percent test
that require it. Based on github pr#368 from ren mingshuai.

Merge 9.1 (#626)
* upstream: fix poll() spin when a channel's output fd closes without
data in the channel buffer. Introduce more exact packing of channel fds into
the pollfd array. fixes bz3405 and bz3411; ok deraadt@ markus@
OpenBSD-Commit-ID: 06740737849c9047785622ad5d472cb6a3907d10
* upstream: select post-quantum KEX
sntrup761x25519-sha512@openssh.com as the default; ok markus@
OpenBSD-Commit-ID: f02d99cbfce22dffec2e2ab1b60905fbddf48fb9
* upstream: add support for the "corp-data" protocol extension to
allow server-side copies to be performed without having to go via the client.
Patch by Mike Frysinger, ok dtucker@
OpenBSD-Commit-ID: 00aa510940fedd66dab1843b58682de4eb7156d5
* upstream: add a sftp client "cp" command that supports server-side
copying of files. Useful for this task and for testing the copy-data
extension. Patch from Mike Frysinger; ok dtucker@
OpenBSD-Commit-ID: 1bb1b950af0d49f0d5425b1f267e197aa1b57444
* depend
* Skip slow tests on (very) slow test targets.
* Set Makefile SHELL as determined by configure.
This should improve compatibility for users with non-POSIX shells. If
using Makefile.in directly (eg make -f Makefile.in distprep) then SHELL
will need to be specified on the command line (along with MANFMT in that
particular case). ok djm@
* Use bash or ksh if available for SH in Makefile.
* Increase test timeout to allow slow VMs to finish
* Only run regression tests on slow VMs.
* Only return events from ppoll that were requested.
If the underlying system's select() returns bits that were not in the
request set, our ppoll() implementation can return revents for events
not requested, which can apparently cause a hang. Only return revents
for activity in the requested event set. bz#3416, analysis and fix by
yaroslav.kuzmin at vmssoftware com, ok djm@
* Specify TEST_SHELL=bash on AIX.
The system shells cause the agent-restrict test to fail due to some
quoting so explicitly specify bash until we can get configure to
autmatically work around that.
* Disable security key on fbsd6 test host.
* upstream: man pages: add missing commas between subordinate and
main clauses
jmc@ dislikes a comma before "then" in a conditional, so leave those
untouched.

* upstream: openssh-9.0
OpenBSD-Commit-ID: 0dfb461188f4513ec024c1534da8c1ce14c20b64
* update version numbers for release
* update build-aux files to match autoconf-2.71
i.e. config.guess, config.sub and install-sh
* Revert "update build-aux files to match autoconf-2.71"
This reverts commit 0a8ca39fac6ad19096b6c263436f8b2dd51606f2.
It turns out that the checked-in copies of these files are actually newer
than autoconf-2.71's copies, so this was effectively a downgrade.
Spotted by Bo Anderson via github
* upstream: two defensive changes from Tobias Stoeckmann via GHPR287
enforce stricter invarient for sshbuf_set_parent() - never allow
a buffer to have a previously-set parent changed.
In sshbuf_reset(), if the reallocation fails, then zero the entire
buffer and not the (potentially smaller) default initial alloc size.
OpenBSD-Commit-ID: 14583203aa5d50ad38d2e209ae10abaf8955e6a9

RFC8731. ok djm@
OpenBSD-Commit-ID: 2ac2b5d642d4cf5918eaec8653cad9a4460b2743
* upstream: clear io_want/io_ready flags at start of poll() cycle;
avoids plausible spin during rekeying if channel io_want flags are reused
across cycles. ok markus@ deraadt@
OpenBSD-Commit-ID: 91034f855b7c73cd2591657c49ac30f10322b967
* Retire fbsd6 test VM.
It's long since out of support, relatively slow (it's i686) and the
compiler has trouble with PIE.
* Resync moduli.5 with upstream.
1.18: remove duplicate publication year; carsten dot kunze at arcor dot de
1.19: ssh-keygen's -G/-T have been replaced with -M generate/screen.
* upstream: Correct path for system known hosts file in description
of IgnoreUserKnownHosts. Patch from Martin Vahlensieck via tech@
OpenBSD-Commit-ID: 9b7784f054fa5aa4d63cb36bd563889477127215

* upstream: Try to continue running local I/O for channels in state
OPEN during SSH transport rekeying. The most visible benefit is that it

OpenBSD-Regress-ID: c96bea9edde3a384b254785e7f9b2b24a81cdf82
* upstream: Simplify forward-control test.
Since we no longer need to support SSH1 we don't need to run shell
commands on the other end of the connection and can use ssh -N instead.
This also makes the test less racy.
OpenBSD-Regress-ID: 32e94ce272820cc398f30b848b2b0f080d10302c
* upstream: Use ssh -f and ControlPersist ..
to start up test forwards and ssh -O stop to shut them down intead of
sleep loops. This speeds up the test by an order of magnitude.
OpenBSD-Regress-ID: eb3db5f805100919b092a3b2579c611fba3e83e7
* upstream: It looks like we can't completely avoid
waiting for processes to exit so retrieve the pid via controlmaster and
use that.

* Cache timezone data in capsicum sandbox.
From emaste at freebsd.org, originally part of FreeBSD commit r339216
/ fc3c19a9 with autoconf bits added by me.
* Include stdlib.h for free() prototype.
... which is used inside the CUSTOM_SYS_AUTH_GET_LASTLOGIN_MSG block.
* Update OpenSSL and LibreSSL versions in tests.
* Add debian-riscv64 test target.
* upstream: Avoid an unnecessary xstrdup in rm_env() when matching
patterns. Since match_pattern() doesn't modify its arguments (they are
const), there is no need to make an extra copy of the strings in
options->send_env. From Martin Vahlensieck
OpenBSD-Commit-ID: 2c9db31e3f4d3403b49642c64ee048b2a0a39351
* upstream: Add missing includes of stdlib.h and stdint.h. We need
stdlib.h for malloc(3) and stdint.h for SIZE_MAX. Unlike the other xmss
files, ssh-xmss.c does not include xmss_commons.h so ssh-xmss.c must include
those headers itself. From Martin Vahlensieck
OpenBSD-Commit-ID: 70e28a9818cee3da1be2ef6503d4b396dd421e6b

* upstream: Add FIDO AUTHENTICATOR section and explain a bit how FIDO
works. The wording came mostly from the 8.2 OpenSSH release notes, addapted
to fit the man page. Then move the -O bits into the new section as is already
done for CERTIFICATES and MODULI GENERATION. Finally we can explain the
trade-offs of resident keys. While here, consistently refer to the FIDO
thingies as "FIDO authenticators", not "FIDO tokens".

* Add ubsan minimal testcase on OpenBSD.
As suggested by djm@.
* Note that, for now, we need variadic macros.
* Also retest OpenBSD upstream on .yml changes.
* upstream: When performing operations that glob(3) a remote path, ensure
that the implicit working directory used to construct that path escapes
glob(3) characters.
This prevents glob characters from being processed in places they
shouldn't, e.g. "cd /tmp/a*/", "get *.txt" should have the get operation
treat the path "/tmp/a*" literally and not attempt to expand it.

* Refuse to use OpenSSL 3.0.4 due to potential RCE.
OpenSSL has a potential RCE in its RSA implementation (CVE-2022-2274)

* Capture stderr output from configure.
* Only refuse to use OpenSSL 3.0.4 on x86_64.
The potential RCE only impacts x86_64, so only refuse to use it if we're
targetting a potentially impacted architecture. ok djm@
* Remove special casing of crypt().
Configure goes to some lengths to pick crypt() from either libcrypt
or OpenSSL's libcrypto because they can more or less featureful (eg
supporting md5-style passwords).
OpenSSL removed its crypt() interface in 2002:
https://github.com/openssl/openssl/commit/69deec58 so these hijinks
should no longer be necessary. This also only links sshd with libcrypt
which is the only thing that needs it. ok djm@
* Clarify README.md text.
Clarify the text about the implications of building without OpenSSL, and
prefix the "configure --help" example command with a "./" so it's likely
to work as-is in more shells. From bz#3461.
* Split README.platform into its own line.
README.platform has general platform-specific information, having it
following text about FIDO2 on the same line could imply that it only
has information about FIDO2.
* Return ERANGE from getcwd() if buffer size is 1.
If getcwd() is supplied a buffer size of exactly 1 and a path of "/", it
could result in a nul byte being written out of array bounds. POSIX says
it should return ERANGE if the path will not fit in the available buffer
(with terminating nul). 1 byte cannot fit any possible path with its nul,
so immediately return ERANGE in that case.
OpenSSH never uses getcwd() with this buffer size, and all current
(and even quite old) platforms that we are currently known to work
on have a native getcwd() so this code is not used on those anyway.

* Remove workarounds for OpenSSL missing AES-GCM.

* Do not link scp, sftp and sftp-server w/ zlib.
Some of our binaries (eg sftp, sftp-server, scp) do not interact with
the channels code and thus do use libraries such as zlib and libcrypto
although they are linked with them. This adds a CHANNELLIBS and starts
by moving zlib into it, which means the aformentioned binaries are no
longer linked against zlib. ok djm@

* Remove seed_rng calls from scp, sftp, sftp-server.

will be to stop linking them against libcrypto. ok djm@

* Move stale-configure check as early as possible.
We added a check in Makefile to catch the case where configure needs to

fido_dev_is_winhello.
* Actually put HAVE_STDINT_H around the stdint.h.
* Rename our getentropy to prevent possible loops.
Since arc4random seeds from getentropy, and we use OpenSSL for that
if enabled, there's the possibility that if we build on a system that
does not have getentropy then run on a system that does have it, then
OpenSSL could end up calling our getentropy and getting stuck in a loop.

There are commands (e.g. "get" or "put") that accept two

Merge 9.1 (#626)
* upstream: fix poll() spin when a channel's output fd closes without
data in the channel buffer. Introduce more exact packing of channel fds into
the pollfd array. fixes bz3405 and bz3411; ok deraadt@ markus@
OpenBSD-Commit-ID: 06740737849c9047785622ad5d472cb6a3907d10
* upstream: select post-quantum KEX
sntrup761x25519-sha512@openssh.com as the default; ok markus@
OpenBSD-Commit-ID: f02d99cbfce22dffec2e2ab1b60905fbddf48fb9
* upstream: add support for the "corp-data" protocol extension to
allow server-side copies to be performed without having to go via the client.
Patch by Mike Frysinger, ok dtucker@
OpenBSD-Commit-ID: 00aa510940fedd66dab1843b58682de4eb7156d5
* upstream: add a sftp client "cp" command that supports server-side
copying of files. Useful for this task and for testing the copy-data
extension. Patch from Mike Frysinger; ok dtucker@
OpenBSD-Commit-ID: 1bb1b950af0d49f0d5425b1f267e197aa1b57444
* depend
* Skip slow tests on (very) slow test targets.
* Set Makefile SHELL as determined by configure.
This should improve compatibility for users with non-POSIX shells. If
using Makefile.in directly (eg make -f Makefile.in distprep) then SHELL
will need to be specified on the command line (along with MANFMT in that
particular case). ok djm@
* Use bash or ksh if available for SH in Makefile.
* Increase test timeout to allow slow VMs to finish
* Only run regression tests on slow VMs.
* Only return events from ppoll that were requested.
If the underlying system's select() returns bits that were not in the
request set, our ppoll() implementation can return revents for events
not requested, which can apparently cause a hang. Only return revents
for activity in the requested event set. bz#3416, analysis and fix by
yaroslav.kuzmin at vmssoftware com, ok djm@
* Specify TEST_SHELL=bash on AIX.
The system shells cause the agent-restrict test to fail due to some
quoting so explicitly specify bash until we can get configure to
autmatically work around that.
* Disable security key on fbsd6 test host.
* upstream: man pages: add missing commas between subordinate and
main clauses
jmc@ dislikes a comma before "then" in a conditional, so leave those
untouched.

default KEX
OpenBSD-Commit-ID: 12545bfa10bcbf552d04d9d9520d0f4e98b0e171
* upstream: openssh-9.0
OpenBSD-Commit-ID: 0dfb461188f4513ec024c1534da8c1ce14c20b64
* update version numbers for release
* update build-aux files to match autoconf-2.71
i.e. config.guess, config.sub and install-sh
* Revert "update build-aux files to match autoconf-2.71"
This reverts commit 0a8ca39fac6ad19096b6c263436f8b2dd51606f2.
It turns out that the checked-in copies of these files are actually newer
than autoconf-2.71's copies, so this was effectively a downgrade.
Spotted by Bo Anderson via github
* upstream: two defensive changes from Tobias Stoeckmann via GHPR287
enforce stricter invarient for sshbuf_set_parent() - never allow
a buffer to have a previously-set parent changed.
In sshbuf_reset(), if the reallocation fails, then zero the entire
buffer and not the (potentially smaller) default initial alloc size.
OpenBSD-Commit-ID: 14583203aa5d50ad38d2e209ae10abaf8955e6a9

RFC8731. ok djm@
OpenBSD-Commit-ID: 2ac2b5d642d4cf5918eaec8653cad9a4460b2743
* upstream: clear io_want/io_ready flags at start of poll() cycle;
avoids plausible spin during rekeying if channel io_want flags are reused
across cycles. ok markus@ deraadt@
OpenBSD-Commit-ID: 91034f855b7c73cd2591657c49ac30f10322b967
* Retire fbsd6 test VM.
It's long since out of support, relatively slow (it's i686) and the
compiler has trouble with PIE.
* Resync moduli.5 with upstream.
1.18: remove duplicate publication year; carsten dot kunze at arcor dot de
1.19: ssh-keygen's -G/-T have been replaced with -M generate/screen.
* upstream: Correct path for system known hosts file in description
of IgnoreUserKnownHosts. Patch from Martin Vahlensieck via tech@
OpenBSD-Commit-ID: 9b7784f054fa5aa4d63cb36bd563889477127215
* upstream: list the correct version number

* upstream: Try to continue running local I/O for channels in state
OPEN during SSH transport rekeying. The most visible benefit is that it

OpenBSD-Regress-ID: c96bea9edde3a384b254785e7f9b2b24a81cdf82
* upstream: Simplify forward-control test.
Since we no longer need to support SSH1 we don't need to run shell
commands on the other end of the connection and can use ssh -N instead.
This also makes the test less racy.
OpenBSD-Regress-ID: 32e94ce272820cc398f30b848b2b0f080d10302c
* upstream: Use ssh -f and ControlPersist ..
to start up test forwards and ssh -O stop to shut them down intead of
sleep loops. This speeds up the test by an order of magnitude.
OpenBSD-Regress-ID: eb3db5f805100919b092a3b2579c611fba3e83e7
* upstream: It looks like we can't completely avoid
waiting for processes to exit so retrieve the pid via controlmaster and

* Update OpenSSL and LibreSSL versions in tests.
* Add debian-riscv64 test target.
* upstream: Avoid an unnecessary xstrdup in rm_env() when matching

const), there is no need to make an extra copy of the strings in
options->send_env. From Martin Vahlensieck
OpenBSD-Commit-ID: 2c9db31e3f4d3403b49642c64ee048b2a0a39351
* upstream: Add missing includes of stdlib.h and stdint.h. We need
stdlib.h for malloc(3) and stdint.h for SIZE_MAX. Unlike the other xmss
files, ssh-xmss.c does not include xmss_commons.h so ssh-xmss.c must include
those headers itself. From Martin Vahlensieck

* upstream: Add FIDO AUTHENTICATOR section and explain a bit how FIDO
works. The wording came mostly from the 8.2 OpenSSH release notes, addapted
to fit the man page. Then move the -O bits into the new section as is already
done for CERTIFICATES and MODULI GENERATION. Finally we can explain the
trade-offs of resident keys. While here, consistently refer to the FIDO
thingies as "FIDO authenticators", not "FIDO tokens".

* Add ubsan minimal testcase on OpenBSD.
As suggested by djm@.
* Note that, for now, we need variadic macros.
* Also retest OpenBSD upstream on .yml changes.
* upstream: When performing operations that glob(3) a remote path, ensure
that the implicit working directory used to construct that path escapes
glob(3) characters.
This prevents glob characters from being processed in places they
shouldn't, e.g. "cd /tmp/a*/", "get *.txt" should have the get operation
treat the path "/tmp/a*" literally and not attempt to expand it.

* Remove special casing of crypt().
Configure goes to some lengths to pick crypt() from either libcrypt
or OpenSSL's libcrypto because they can more or less featureful (eg
supporting md5-style passwords).
OpenSSL removed its crypt() interface in 2002:
https://github.com/openssl/openssl/commit/69deec58 so these hijinks
should no longer be necessary. This also only links sshd with libcrypt
which is the only thing that needs it. ok djm@
* Clarify README.md text.
Clarify the text about the implications of building without OpenSSL, and
prefix the "configure --help" example command with a "./" so it's likely
to work as-is in more shells. From bz#3461.
* Split README.platform into its own line.
README.platform has general platform-specific information, having it
following text about FIDO2 on the same line could imply that it only
has information about FIDO2.
* Return ERANGE from getcwd() if buffer size is 1.
If getcwd() is supplied a buffer size of exactly 1 and a path of "/", it
could result in a nul byte being written out of array bounds. POSIX says
it should return ERANGE if the path will not fit in the available buffer
(with terminating nul). 1 byte cannot fit any possible path with its nul,
so immediately return ERANGE in that case.
OpenSSH never uses getcwd() with this buffer size, and all current
(and even quite old) platforms that we are currently known to work
on have a native getcwd() so this code is not used on those anyway.

* Do not link scp, sftp and sftp-server w/ zlib.
Some of our binaries (eg sftp, sftp-server, scp) do not interact with

Since arc4random seeds from getentropy, and we use OpenSSL for that

OpenSSL could end up calling our getentropy and getting stuck in a loop.

* Remove arc4random_uniform from arc4random.c
This was previously moved into its own file (matching OpenBSD) which
prematurely committed in commit 73541f2.
* Move OPENBSD ORIGINAL marker.
Putting this after the copyright statement (which doesn't change)
instead of before the version identifier (which does) prevents merge
conflicts when resyncing changes.
* Resync arc4random with OpenBSD.
This brings us up to current, including djm's random-reseeding change,

non-existent commands
If user entered a non-existent command (e.g. because they made a
typo) there is no point in trying to complete its arguments. Skip
calling complete_match() if that's the case.
From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Skip slow tests on (very) slow test targets.
* Set Makefile SHELL as determined by configure.
This should improve compatibility for users with non-POSIX shells. If
using Makefile.in directly (eg make -f Makefile.in distprep) then SHELL
will need to be specified on the command line (along with MANFMT in that
particular case). ok djm@
* Use bash or ksh if available for SH in Makefile.
* Increase test timeout to allow slow VMs to finish
* Only run regression tests on slow VMs.
* Only return events from ppoll that were requested.
If the underlying system's select() returns bits that were not in the
request set, our ppoll() implementation can return revents for events
not requested, which can apparently cause a hang. Only return revents
for activity in the requested event set. bz#3416, analysis and fix by

It turns out that the checked-in copies of these files are actually newer
than autoconf-2.71's copies, so this was effectively a downgrade.

treat the path "/tmp/a*" literally and not attempt to expand it.

* Remove special casing of crypt().
Configure goes to some lengths to pick crypt() from either libcrypt
or OpenSSL's libcrypto because they can more or less featureful (eg
supporting md5-style passwords).
OpenSSL removed its crypt() interface in 2002:
https://github.com/openssl/openssl/commit/69deec58 so these hijinks
should no longer be necessary. This also only links sshd with libcrypt
which is the only thing that needs it. ok djm@
* Clarify README.md text.
Clarify the text about the implications of building without OpenSSL, and
prefix the "configure --help" example command with a "./" so it's likely
to work as-is in more shells. From bz#3461.
* Split README.platform into its own line.
README.platform has general platform-specific information, having it
following text about FIDO2 on the same line could imply that it only
has information about FIDO2.
* Return ERANGE from getcwd() if buffer size is 1.
If getcwd() is supplied a buffer size of exactly 1 and a path of "/", it
could result in a nul byte being written out of array bounds. POSIX says
it should return ERANGE if the path will not fit in the available buffer
(with terminating nul). 1 byte cannot fit any possible path with its nul,
so immediately return ERANGE in that case.
OpenSSH never uses getcwd() with this buffer size, and all current
(and even quite old) platforms that we are currently known to work
on have a native getcwd() so this code is not used on those anyway.

* Do not link scp, sftp and sftp-server w/ zlib.
Some of our binaries (eg sftp, sftp-server, scp) do not interact with

Since arc4random seeds from getentropy, and we use OpenSSL for that

OpenSSL could end up calling our getentropy and getting stuck in a loop.

From Michal Privoznik
OpenBSD-Commit-ID: cf39c811a68cde2aeb98fc85addea4000ef6b07a
* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

Move keytype data and some of the type-specific code (allocation,
cleanup, etc) out into each key type's implementation. Subsequent
commits will move more, with the goal of having each key-*.c file
owning as much of its keytype's implementation as possible.

* Avoid assuming layout of fd_set
POSIX doesn't specify the internal layout of the fd_set object, so let's
not assume it is just a bit mask. This increases compatibility with
systems that have a different layout.
The assumption is also worthless as we already refuse to use file
descriptors over FD_SETSIZE anyway. Meaning that the default size of
fd_set is quite sufficient.

OpenSSL 1.1.1 has a bug in its RNG that breaks reexec fallback, so skip

* Remove seed passing over reexec.
This was added for the benefit of platforms using ssh-rand-helper to
prevent a delay on each connection as sshd reseeded itself.
ssh-random-helper is long gone, and since the re-exec happens before the
chroot the re-execed sshd can reseed itself normally. ok djm@

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

Different timeouts may be applied to session, X11, agent and TCP forwarding

Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

OpenBSD-Regress-ID: 5451cad59ba0d43ae9eeda48ec80f54405fee969
* upstream: remove whitespace at EOL from code extracted from SUPERCOP
OpenBSD-Commit-ID: 1ec524ff2fbb9387d731601437c82008f35a60f4
* upstream: ignore bogus upload/download buffer lengths in the limits
extension
OpenBSD-Commit-ID: c5b023e0954693ba9a5376e4280c739b5db575f8
* upstream: clamp the minimum buffer lengths and number of inflight
requests too
OpenBSD-Commit-ID: c4965f62fa0ba850940fd66ae3f60cf516bbcd56
* upstream: avoid printf("%s", NULL) if using ssh
-oUserKnownHostsFile=none and a hostkey in one of the system known hosts file
changes; ok dtucker@
OpenBSD-Commit-ID: 7ca87614bfc6da491315536a7f2301434a9fe614
* upstream: Add a "Host" line to the output of ssh -G showing the
original host arg. Inspired by patch from vincent at bernat.ch via bz#3343,
ok djm@
OpenBSD-Commit-ID: 59c0f60a222113a44d0650cd394376e3beecc883
* Remove skipping test when scp not in path.
An upcoming change renders this obsolete by adding scp's path to the
test sshd's PATH, and removing this first will make the subsequent sync
easier.
* upstream: Add scp's path to test sshd's PATH.
If the scp we're testing is fully qualified (eg it's not in the system
PATH) then add its path to the under-test sshd's PATH so we can find
it. Prompted by bz#3518.
OpenBSD-Regress-ID: 7df4f5a0be3aa135495b7e5a6719d3cbc26cc4c0
* upstream: Move scp path setting to a helper function. The previous
commit to add scp to the test sshd's path causes the t-envpass test to fail
when the test scp is given using a fully qualified path. Put this in a
helper function and only call it from the scp tests.
OpenBSD-Regress-ID: 7533dc1c4265c1de716abb062957994195b36df4
* Retry package installation 3 times.
When setting up the CI environment, retry package installation 3 times
before going up. Should help prevent spurious failures during
infrastructure issues.
* upstream: Document "UserKnownHostsFile none". ok djm@
OpenBSD-Commit-ID: f695742d39e34ecdcc3c861c3739a84648a4bce5
* upstream: fix double phrase in previous;
OpenBSD-Commit-ID: 671e6c8dc5e9230518b2bbfa143daaa88adc66c2
* upstream: Instead of skipping the all-tokens test if we don't have
OpenSSL (since we use it to compute the hash), put the hash at the end and
just omit it if we don't have it. Prompted by bz#3521.
OpenBSD-Regress-ID: c79ecba64250ed3b6417294b6c965e6b12ca5eea
* upstream: Shell syntax fix. From ren mingshuai vi github PR#369.
OpenBSD-Regress-ID: 6696b2eeefe128099fc3d7ea9f23252cc35156f9
* Allow writev is seccomp sandbox.
This seems to be used by recent glibcs at least in some configurations.
From bz#3512, ok djm@
* upstream: update OpenSSH's Ed25519 code to the last version of SUPERCOP
(20221122) and change the import approach to the same one we use for
Streamlined NTRUPrime: use a shell script to extract the bits we need from
SUPERCOP, make some minor adjustments and squish them all into a single file.
ok tb@ tobhe@
OpenBSD-Commit-ID: 1bc0fd624cb6af440905b8ba74ac7c03311b8e3b
* upstream: adapt to ed25519 changes in src/usr.bin/ssh
OpenBSD-Regress-ID: 4b3e7ba7ee486ae8a0b4790f8112eded2bb7dcd5
* upstream: Add a sshd_config UnusedConnectionTimeout option to terminate
client connections that have no open channels for some length of time. This
complements the recently-added ChannelTimeout option that terminates inactive
channels after a timeout.
ok markus@
OpenBSD-Commit-ID: ca983be74c0350364c11f8ba3bd692f6f24f5da9
* upstream: unbreak test: cannot access shell positional parameters
past $9 without wrapping the position in braces (i.e. need ${10}, etc.)
OpenBSD-Regress-ID: 3750ec98d5d409ce6a93406fedde6f220d2ea2ac
* upstream: regression test for UnusedConnectionTimeout
OpenBSD-Regress-ID: 7f29001374a68e71e5e078f69e4520cf4bcca084
* upstream: also check that an active session inhibits
UnusedConnectionTimeout idea markus@
OpenBSD-Regress-ID: 55c0fb61f3bf9e092b0a53f9041d3d2012f14003
* upstream: For "ssh -V" always exit 0, there is no need to check opt
again. This was missed when the fallthrough in the switch case above it was
removed. OK deraadt@
OpenBSD-Commit-ID: 5583e5d8f6d62a8a4215cfa95a69932f344c8120
* upstream: Add a -V (version) option to sshd like the ssh client
has. OK markus@ deraadt@
OpenBSD-Commit-ID: abe990ec3e636fb040132aab8cbbede98f0c413e
* upstream: when restoring non-blocking mode to stdio fds, restore
exactly the flags that ssh started with and don't just clobber them with
zero, as this could also remove the append flag from the set;
bz3523; ok dtucker@
OpenBSD-Commit-ID: 1336b03e881db7564a4b66014eb24c5230e9a0c0
* Skip connection-timeout when missing FD passing.
This tests uses multiplexing which uses file descriptor passing, so
skip it if we don't have that. Fixes test failures on Cygwin.
* Skip connection-timeout test under Valgrind.
Valgrind slows things down so much that the timeout test fails. Skip
this test until we figure out if we can make it work.
* upstream: tweak previous; ok djm
OpenBSD-Commit-ID: df71ce4180c58202dfdc1d92626cfe900b91b7c3
* upstream: Create and install sshd random relink kit.
../Makefile.inc and Makfile are concatenated for reuse, which hopefully won't
be too fragile, we'll see if we need a different approach. The resulting sshd
binary is tested with the new sshd -V option before installation. As the
binary layout is now semi-unknown (meaning relative, fixed, and gadget
offsets are not precisely known), change the filesystem permissions to 511 to
prevent what I call "logged in BROP". I have ideas for improving this further
but this is a first step ok djm
OpenBSD-Commit-ID: 1e0a2692b7e20b126dda60bf04999d1d30d959d8
* upstream: delete useless dependency
OpenBSD-Commit-ID: e1dc11143f83082e3154d6094f9136d0dc2637ad
* fix libfido2 detection without pkg-config
Place libfido2 before additional libraries (that it may depend upon)
and not after. bz3530 from James Zhang; ok dtucker@
* Skip connection-timeout test on minix3.
Minix 3's Unix domain sockets don't seem to work the way we expect, so
skip connection-timeout test on that platform. While there, group
together all similarly skipped tests and explicitly comment.
* upstream: fix double-free caused by compat_kex_proposal(); bz3522
by dtucker@, ok me
OpenBSD-Commit-ID: 2bfc37cd2d41f67dad64c17a64cf2cd3806a5c80
* upstream: openssh-9.2
OpenBSD-Commit-ID: f7389f32413c74d6e2055f05cf65e7082de03923
* upstream: Check if we can copy sshd or need to use sudo to do so
during reexec test. Skip test if neither can work. Patch from anton@, tweaks
from me.
OpenBSD-Regress-ID: 731b96ae74d02d5744e1f1a8e51d09877ffd9b6d
* upstream: test compat_kex_proposal(); by dtucker@
OpenBSD-Regress-ID: 0e404ee264db546f9fdbf53390689ab5f8d38bf2

* update version in README
* crank versions in RPM specs
* remove files from libssh project
* re-merge arc4random.c
* re-merge misc.c
* remove unused files from libssh.vcxproj
* fix outstanding merge conflicts
* fix build errors
* modify upstream workflows to trigger on workflow dispatch instead of all PRs
* fix scp client hanging with pipes
* fix some failing bash tests
* make bash test compatible with Windows
* address scp's sftp mode buf len limitations
* address review feedback
* address review feedback
* update comment
