ssh: Update to OpenSSH 9.7p1

This release contains mostly bugfixes.

It also makes support for the DSA signature algorithm a compile-time
option, with plans to disable it upstream later this year and remove
support entirely in 2025.

ssh: Update to OpenSSH 9.6p1

From the release notes,

> This release contains a number of security fixes, some small features
> and bugfixes.

The most significant change in 9.6p1 is a set of fixes for a newly-
discovered weakness in the SSH transport protocol.  The fix was already
merged into FreeBSD and released as FreeBSD-SA-23:19.openssh.

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: disallow loading PKCS#11 modules by default

This is the rest of the OpenSSH 9.3p2 change to address CVE-2023-38408.

From the release notes:

 * ssh-agent(8): the agent will now refuse requests to load PKCS#11
   modules issued by remote clients by default. A flag has been added
   to restore the previous behaviour "-Oallow-remote-pkcs11".

   Note that ssh-agent(8) depends on the SSH client to identify
   requests that are remote. The OpenSSH >=8.9 ssh(1) client does
   this, but forwarding access to an agent socket using other tools
   may circumvent this restriction.

ssh: Update to OpenSSH 9.3p2

From the release notes:

Changes since OpenSSH 9.3
=========================

This release fixes a security bug.

Security
========

Fix CVE-2023-38408 - a condition where specific libaries loaded via
ssh-agent(1)'s PKCS#11 support could be abused to achieve remote
code execution via a forwarded agent socket if the following
conditions are met:

* Exploitation requires the presence of specific libraries on
  the victim system.

ssh: Update to OpenSSH 9.3p1

This release fixes a number of security bugs and has minor new
features and bug fixes.  Security fixes, from the release notes
(https://www.openssh.com/txt/release-9.3):

This release contains fixes for a security problem and a memory
safety problem. The memory safety problem is not believed to be
exploitable, but we report most network-reachable memory faults as
security bugs.

 * ssh-add(1): when adding smartcard keys to ssh-agent(1) with the
   per-hop destination constraints (ssh-add -h ...) added in OpenSSH
   8.9, a logic error prevented the constraints from being
   communicated to the agent. This resulted in the keys being added
   without constraints. The common cases of non-smartcard keys and
   keys without destination constraints are unaffected. This problem
   was reported by Luci Stanescu.

ssh: update to OpenSSH 9.2p1

Release notes are available at https://www.openssh.com/txt/release-9.2

OpenSSH 9.2 contains fixes for two security problems and a memory safety
problem.  The memory safety problem is not believed to be exploitable.
These fixes have already been committed to OpenSSH 9.1 in FreeBSD.

Some other notable items from the release notes:

 * ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that
   controls whether the client-side ~C escape sequence that provides a
   command-line is available. Among other things, the ~C command-line
   could be used to add additional port-forwards at runtime.

 * sshd(8): add support for channel inactivity timeouts via a new
   sshd_config(5) ChannelTimeout directive. This allows channels that
   have not seen traffic in a configurable interval to be
   automatically closed. Different timeouts may be applied to session,

9.1 contains fixes for three minor memory safety problems; these have
lready been merged to the copy of OpenSSH 9.0 that is in the FreeBSD base
system.

Some highlights copied from the release notes:

Potentially-incompatible changes
--------------------------------

 * 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
