* 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

* 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.

* 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@.

Now that all FIDO signing calls attempt first without PIN and then

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.

* Split out rekey test since it runs the longest.

Update actions/checkout and actions/upload-artifact to main branch for

* 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
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

* 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.

i.e. config.guess, config.sub and install-sh

* Revert "update build-aux files to match autoconf-2.71"

This reverts commit 0a8ca39fac.

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.

* upstream: two defensive changes from Tobias Stoeckmann via GHPR287

enforce stricter invarient for sshbuf_set_parent() - never allow

In sshbuf_reset(), if the reallocation fails, then zero the entire
buffer and not the (potentially smaller) default initial alloc size.

* 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.

part of GHPR329 from Pedro Martelletto

OpenBSD-Commit-ID: 75d1005bd2ef8f29fa834c90d2684e73556fffe8

* crank SSH_SK_VERSION_MAJOR in sk-dummy.so

* Skip scp3 test if there's no scp on remote path.

scp -3 ends up using the scp that's in the remote path and will fail if
one is not available.  Based on a patch from rapier at psc.edu.

* Convert "have_prog" function into "which".

"which" and its behaviour is not standardized, so convert the existing
have_prog function into "which" so we can rely on it being available
and what its semantics are.  Add a have_prog wrapper that maintains the
existing behaviour.

* upstream: Test TEST_SSH_ELAPSED_TIMES for empty string not

* Remove workarounds for OpenSSL missing AES-GCM.

We have some compatibility hacks that were added to support OpenSSL
versions that do not support AES GCM mode.  Since that time, however,
the minimum OpenSSL version that we support has moved to 1.0.1 which
*does* have GCM, so this is no longer needed.  ok djm@

* Remove workarounds for OpenSSL missing AES-CTR.

We have some compatibility hacks that were added to support OpenSSL
versions that do not support AES CTR mode.  Since that time, however,
the minimum OpenSSL version that we support has moved to 1.0.1 which
*does* have CTR, so this is no longer needed.  ok djm@

* 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@

* Group libcrypto and PRNGD checks together.

They're related more than the libcrypt or libiaf checks which are
currently between them.  ok djm@

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

These binaries don't use OpenSSL's random functions.  The next step
will be to stop linking them against libcrypto.  ok djm@

* Move libcrypto into CHANNELLIBS.

This will result in sftp, sftp-server and scp no longer being linked
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
be rebuilt, however this did not happen until a build was attempted in
which case all of the work done by configure was wasted.  Move this check
 to the start of configure to catch it as early as possible.  ok djm@

* compat code for fido_dev_is_winhello()

Signed-off-by: Corinna Vinschen <vinschen@redhat.com>

* check_sk_options: add temporary WinHello workaround

Up to libfido 1.10.0, WinHello advertises "clientPin" rather
than "uv" capability.  This is fixed in 1.11.0.  For the time
being, workaround it here.

Signed-off-by: Corinna Vinschen <vinschen@redhat.com>

* sk_sign: set FIDO2 uv attribute explicitely for WinHello

WinHello via libfido2 performs user verification by default.
However, if we stick to that, there's no way to differentiate
between keys created with or without "-O  verify-required".
Set FIDO2 uv attribute explicitely to FIDO_OPT_FALSE, then check
if user verification has been requested.

* upstream: don't prompt for FIDO passphrase before attempting to enroll

the credential, just let the enroll operating fail and we'll attempt to get a
PIN anyway. Might avoid some unneccessary PIN prompts.

OpenBSD-Commit-ID: bd5342ffc353ee37d39617906867c305564d1ce2

* Give unused param a name.

Fixes builds on platforms that do have fido2 but don't have
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.

* Test hostbased auth on github runners.

* fix SANDBOX_SECCOMP_FILTER_DEBUG

* Fix conditional for running hostbased tests.

* upstream: allow certificate validity intervals, sshsig verification

times and authorized_keys expiry-time options to accept dates in the UTC time
zone in addition to the default of interpreting them in the system time zone.
YYYYMMDD and YYMMDDHHMM[SS] dates/times will be interpreted as UTC if
suffixed with a 'Z' character.

Also allow certificate validity intervals to be specified in raw
seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This
is intended for use by regress tests and other tools that call
ssh-keygen as part of a CA workflow.

* Skip hostbased during Valgrind tests.

Valgrind doesn't let ssh exec ssh-keysign (because it's setuid) so skip
it during the Valgrind based tests.

See https://bugs.kde.org/show_bug.cgi?id=119404 for a discussion of this
(ironically there the problematic binary was ssh(1) back when it could
still be setuid).

* Add a timegm implementation from Heimdal via Samba.

* Replace deprecated ubuntu-18.04 runners with 22.04

* upstream: sftp-server: support home-directory request

Add support to the sftp-server for the home-directory extension defined
in draft-ietf-secsh-filexfer-extensions-00. This overlaps a bit with the
existing expand-path@openssh.com, but uses a more official protocol name,
and so is a bit more likely to be implemented by non-OpenSSH clients.

* 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.

djm@openbsd.org 312d2f2861 upstream: repair PubkeyAcceptedKeyTypes (and friends) after RSA
signature work - returns ability to add/remove/specify algorithms by
wildcard.

Algorithm lists are now fully expanded when the server/client configs
are finalised, so errors are reported early and the config dumps
(e.g. "ssh -G ...") now list the actual algorithms selected.

Clarify that, while wildcards are accepted in algorithm lists, they
aren't full pattern-lists that support negation.

(lots of) feedback, ok markus@

djm@openbsd.org 4ba0d54794 upstream: Improve strictness and control over RSA-SHA2 signature
In ssh, when an agent fails to return a RSA-SHA2 signature when
requested and falls back to RSA-SHA1 instead, retry the signature to
ensure that the public key algorithm sent in the SSH_MSG_USERAUTH
matches the one in the signature itself.

In sshd, strictly enforce that the public key algorithm sent in the
SSH_MSG_USERAUTH message matches what appears in the signature.

Make the sshd_config PubkeyAcceptedKeyTypes and
HostbasedAcceptedKeyTypes options control accepted signature algorithms
(previously they selected supported key types). This allows these
options to ban RSA-SHA1 in favour of RSA-SHA2.

Add new signature algorithms "rsa-sha2-256-cert-v01@openssh.com" and
"rsa-sha2-512-cert-v01@openssh.com" to force use of RSA-SHA2 signatures
with certificate keys.

Drop compatibility hacks for some ancient SSH

These versions were all released in or before 2001 and predate the
final SSH RFCs. The hacks in question aren't necessary for RFC-
