* 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.

tokens) and enable UV in that case. From Pedro Martelletto via GHPR#388

* 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
causes spurious "incorrect signature" failures with ED25519.  On those
versions, use -fzero-call-used-regs=used instead.  (We may add exceptions

* 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.

Darren Tucker 48d0d7a4dd Disable sntrup761 if compiler doesn't support VLAs.
The sntrup761 code sourced from supercop uses variable length
arrays.  Although widely supported, they are not part of the ANSI
C89 spec so if the compiler does not support VLAs, disable the
sntrup761x25519-sha512@openssh.com KEX method by replacing the kex
functions with no-op ones similar to what we do in kexecdh.c.

This should allow OpenSSH to build with a plain C89 compiler again.

Damien Miller 148b8a661c fix: missing pieces of previous commit 2020-12-31 12:47:22 +11:00
djm@openbsd.org 2c71cec020 upstream: Update/replace the experimental post-quantim hybrid key
exchange method based on Streamlined NTRU Prime (coupled with X25519).

The previous sntrup4591761x25519-sha512@tinyssh.org method is
replaced with sntrup761x25519-sha512@openssh.com. Per the authors,
sntrup4591761 was replaced almost two years ago by sntrup761.

The sntrup761 implementaion, like sntrup4591761 before it, is public
domain code extracted from the SUPERCOP cryptography benchmark
suite (https://bench.cr.yp.to/supercop.html).

Thanks for Daniel J Bernstein for guidance on algorithm selection.
Patch from Tobias Heider; feedback & ok markus@ and myself

(note this both the updated method and the one that it replaced are
disabled by default)
