Hi Damien,
I want to report success on OpenIndida OS:
:; ssh -V
OpenSSH_9.1p1-snap20220928, OpenSSL 1.1.1q 5 Jul 2022
Compiled with GCC 10 (with custom OpenSSL and MIT Kerberos-5 compilation)
Tested server and client (briefly, for functionality used to use on
everyday tasks) -- all works fine...
Thanks and regards

Hi,
OpenSSH 9.1p1 is almost ready for release, so we would appreciate testing
on as many platforms and systems as possible. This is a bugfix release.
Snapshot releases for portable OpenSSH are available from
http://www.mindrot.org/openssh_snap/
The OpenBSD version is available in CVS HEAD:
http://www.openbsd.org/anoncvs.html
Portable OpenSSH is also available via git using the
instructions at http://www.openssh.com/portable.html#cvs
At https://anongit.mindrot.org/openssh.git/ or via a mirror at Github:
https://github.com/openssh/openssh-portable
Running the regression tests supplied with Portable OpenSSH does not
require installation and is a simply:
$ ./configure && make tests
Live testing on suitable non-production systems is also appreciated.
Please send reports of success or failure to
openssh-unix-dev@xxxxxxxxxxx. Security bugs should be reported
directly to openssh@xxxxxxxxxxx.
Below is a summary of changes. More detail may be found in the ChangeLog
in the portable OpenSSH tarballs.
Thanks to the many people who contributed to this release.
Potentially-incompatible changes
--------------------------------
* The portable OpenSSH project now signs commits and release tags
using git's recent SSH signature support. The list of developer
signing keys is included in the repository as .git_allowed_signers
and is cross-signed using the PGP key that is still used to sign
release artifacts:
https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/RELEASE_KEY.asc
* ssh(1), sshd(8): SetEnv directives in ssh_config and sshd_config
are now first-match-wins to match other directives. Previously
if an environment variable was multiply specified the last set
value would have been used. bz3438
* ssh-keygen(8): ssh-keygen -A (generate all default host key types)
will no longer generate DSA keys, as these are insecure and have
not been used by default for some years.
New features
------------
* ssh(1), sshd(8): add a RequiredRSASize directive to set a minimum
RSA key length. Keys below this length will be ignored for user
authentication and for host authentication in sshd(8).
ssh(1) will terminate a connection if the server offers an RSA key
that falls below this limit, as the SSH protocol does not include
the ability to retry a failed key exchange.
* sftp-server(8): add a "users-groups-by-id@xxxxxxxxxxx" extension
request that allows the client to obtain user/group names that
correspond to a set of uids/gids.
* sftp(1): use "users-groups-by-id@xxxxxxxxxxx" sftp-server
extension (when available) to fill in user/group names for
directory listings.
* sftp-server(8): support the "home-directory" extension request
defined in draft-ietf-secsh-filexfer-extensions-00. This overlaps
a bit with the existing "expand-path@xxxxxxxxxxx", but some other
clients support it.
* ssh-keygen(1), sshd(8): 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. bz3468
* sftp(1): allow arguments to the sftp -D option, e.g. sftp -D
"/usr/libexec/sftp-server -el debug3"
* ssh-keygen(1): allow the existing -U (use agent) flag to work
with "-Y sign" operations, where it will be interpreted to require
that the private keys is hosted in an agent; bz3429
Bugfixes
--------
* ssh-keygen(1): implement the "verify-required" certificate option.
This was already documented when support for user-verified FIDO
keys was added, but the ssh-keygen(1) code was missing.
* ssh-agent(1): hook up the restrict_websafe command-line flag;
previously the flag was accepted but never actually used.
* sftp(1): improve filename tab completions: never try to complete
names to non-existent commands, and better match the completion
type (local or remote filename) against the argument position
being completed.
* ssh-keygen(1), ssh(1), ssh-agent(1): several fixes to FIDO key
handling, especially relating to keys that request
user-verification. These should reduce the number of unnecessary
PIN prompts for keys that support intrinsic user verification.
GHPR302, GHPR329
* ssh-keygen(1): when enrolling a FIDO resident key, check if a
credential with matching application and user ID strings already
exists and, if so, prompt the user for confirmation before
overwriting the credential. GHPR329
* sshd(8): improve logging of errors when opening authorized_keys
files. bz2042
* ssh(1): avoid multiplexing operations that could cause SIGPIPE from
causing the client to exit early. bz3454
* ssh_config(5), sshd_config(5): clarify that the RekeyLimit
directive applies to both transmitted and received data. GHPR328
* ssh-keygen(1): avoid double fclose() in error path.
* sshd(8): log an error if pipe() fails while accepting a
connection. bz3447
* ssh(1), ssh-keygen(1): fix possible NULL deref when built without
FIDO support. bz3443
* ssh-keyscan(1): add missing *-sk types to ssh-keyscan manpage.
GHPR294.
* sshd(8): ensure that authentication passwords are cleared from
memory in error paths. GHPR286
* ssh(1), ssh-agent(1): avoid possibility of notifier code executing
kill(-1). GHPR286
* ssh_config(5): note that the ProxyJump directive also accepts the
same tokens as ProxyCommand. GHPR305.
* scp(1): do not not ftruncate(3) files early when in sftp mode. The
previous behaviour of unconditionally truncating the destination
file would cause "scp ~/foo localhost:foo" and the reverse
"scp localhost:foo ~/foo" to delete all the contents of their
destination. bz3431
* ssh-keygen(1): improve error message when 'ssh-keygen -Y sign' is
unable to load a private key; bz3429
* sftp(1), scp(1): 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.
* ssh(1), sshd(8): be stricter in which characters will be accepted
in specifying a mask length; allow only 0-9. GHPR278
* ssh-keygen(1): avoid printing hash algorithm twice when dumping a
KRL
* ssh(1), sshd(8): continue running local I/O for open channels
during SSH transport rekeying. This should make ~-escapes work in
the client (e.g. to exit) if the connection happened to have
stalled during a rekey event.
* ssh(1), sshd(8): avoid potential poll() spin during rekeying
* Further hardening for sshbuf internals: disallow "reparenting" a
hierarchical sshbuf and zero the entire buffer if reallocation
fails. GHPR287
Portability
-----------
* ssh(1), ssh-keygen(1), sshd(8): automatically enable the built-in
FIDO security key support if libfido2 is found and usable, unless
--without-security-key-builtin was requested.
* ssh(1), ssh-keygen(1), sshd(8): many fixes to make the WinHello
FIDO device usable on Cygwin. The windows://hello FIDO device will
be automatically used by default on this platform unless requested
otherwise, or when probing resident FIDO credentials (an operation
not currently supported by WinHello).
* Portable OpenSSH: remove workarounds for obsolete and unsupported
versions of OpenSSL libcrypto. In particular, this release removes
fallback support for OpenSSL that lacks AES-CTR or AES-GCM.
Those AES cipher modes were added to OpenSSL prior to the minimum
version currently supported by OpenSSH, so this is not expected to
impact any currently supported configurations.
* sshd(8): fix SANDBOX_SECCOMP_FILTER_DEBUG on current Linux/glibc
* All: resync and clean up internal CSPRNG code.
* scp(1), sftp(1), sftp-server(8): avoid linking these programs with
unnecessary libraries. They are no longer linked against libz and
libcrypto. This may be of benefit to space constrained systems
using any of those components in isolation.
* sshd(8): add AUDIT_ARCH_PPC to supported seccomp sandbox
architectures.
* configure: remove special casing of crypt(). configure will no
longer search for crypt() in libcrypto, as it was removed from
there years ago. configure will not only search libc and libcrypt.
* configure: refuse to use OpenSSL 3.0.4 due to potential RCE in its
RSA implementation (CVE-2022-2274) on x86_64.
* All: request 1.1x API compatibility for OpenSSL >=3.x; GHPR#322
* ssh(1), ssh-keygen(1), sshd(8): fix a number of missing includes
required by the XMSS code on some platforms.
* sshd(8): cache timezone data in capsicum sandbox.
