Ed Maste 535af610a4 ssh: Update to OpenSSH 9.4p1
Excerpts from the release notes:

 * ssh-agent(1): PKCS#11 modules must now be specified by their full
   paths. Previously dlopen(3) could search for them in system
   library directories.

 * ssh(1): allow forwarding Unix Domain sockets via ssh -W.

 * ssh(1): add support for configuration tags to ssh(1).
   This adds a ssh_config(5) "Tag" directive and corresponding
   "Match tag" predicate that may be used to select blocks of
   configuration similar to the pf.conf(5) keywords of the same
   name.

 * ssh(1): add a "match localnetwork" predicate. This allows matching
   on the addresses of available network interfaces and may be used to
   vary the effective client configuration based on network location.

 * ssh-agent(1): improve isolation between loaded PKCS#11 modules
   by running separate ssh-pkcs11-helpers for each loaded provider.

 * ssh-agent(1), ssh(1): improve defences against invalid PKCS#11
   modules being loaded by checking that the requested module
   contains the required symbol before loading it.

 * ssh(1): don't incorrectly disable hostname canonicalization when
   CanonicalizeHostname=yes and ProxyJump was expicitly set to
   "none". bz3567

See https://www.openssh.com/releasenotes.html#9.4p1 for the release
notes.
Please read https://www.openssh.com/report.html for bug reporting
instructions and note that we do not use Github for bug reporting or
patch/pull-request management.
This is the port of OpenBSD's excellent OpenSSH[0] to Linux and other
Unices.
OpenSSH is based on the last free version of Tatu Ylonen's sample
implementation with all patent-encumbered algorithms removed (to
external libraries), all known security bugs fixed, new features
reintroduced and many other clean-ups. OpenSSH has been created by
Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos, Theo de Raadt,
and Dug Song. It has a homepage at https://www.openssh.com/
This port consists of the re-introduction of autoconf support, PAM
support, EGD/PRNGD support and replacements for OpenBSD library
functions that are (regrettably) absent from other unices. This port
has been best tested on AIX, Cygwin, HP-UX, Linux, MacOS/X,
FreeBSD, NetBSD, OpenBSD, OpenServer, Solaris and UnixWare.
This version actively tracks changes in the OpenBSD CVS repository.
The PAM support is now more functional than the popular packages of
commercial ssh-1.2.x. It checks "account" and "session" modules for
all logins, not just when using password authentication.
There is now several mailing lists for this port of OpenSSH. Please
refer to https://www.openssh.com/list.html for details on how to join.
Please send bug reports and patches to https://bugzilla.mindrot.org or
the mailing list openssh-unix-dev@mindrot.org. To mitigate spam, the
list only allows posting from subscribed addresses. Code contribution
are welcomed, but please follow the OpenBSD style guidelines[1].
Please refer to the INSTALL document for information on dependencies and
how to install OpenSSH on your system.

Miscellania -
This version of OpenSSH is based upon code retrieved from the OpenBSD CVS
repository which in turn was based on the last free sample implementation
released by Tatu Ylonen.
