openssh: Update to version 9.4p1

openssh: Update to version 9.4p1

- Update from version 9.3p2 to 9.4p1
- Update of rootfile not required.
- The openssh check for zlib version incorrectly identifies version 1.3 as being older
   than the buggy zlib version. This bug was found on the oipenssh github pull request page
   but merged after openssh-9.4p1 was issued. Patch implemented to fix zlib version
   identification. This and the autoconf line can be removed when the next version of
   openssh is released.
- Changelog
    9.4p1
	This release fixes a number of bugs and adds some small features.
	Potentially incompatible changes
		 * This release removes support for older versions of libcrypto.
		   OpenSSH now requires LibreSSL >= 3.1.0 or OpenSSL >= 1.1.1.
		   Note that these versions are already deprecated by their upstream
		   vendors.
		 * 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.
	New features
		 * 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(1), sshd(8), ssh-keygen(1): infrastructure support for KRL
		   extensions.  This defines wire formats for optional KRL extensions
		   and implements parsing of the new submessages. No actual extensions
		   are supported at this point.
		 * sshd(8): AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
		   accept two additional %-expansion sequences: %D which expands to
		   the routing domain of the connected session and %C which expands
		   to the addresses and port numbers for the source and destination
		   of the connection.
		 * ssh-keygen(1): increase the default work factor (rounds) for the
		   bcrypt KDF used to derive symmetric encryption keys for passphrase
		   protected key files by 50%.
	Bugfixes
		 * ssh-agent(1): improve isolation between loaded PKCS#11 modules
		   by running separate ssh-pkcs11-helpers for each loaded provider.
		 * ssh(1): make -f (fork after authentication) work correctly with
		   multiplexed connections, including ControlPersist. bz3589 bz3589
		 * ssh(1): make ConnectTimeout apply to multiplexing sockets and not
		   just to network connections.
		 * 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.
		 * sshd(8): fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
		   appears before it in sshd_config. Since OpenSSH 8.7 the
		   AuthorizedPrincipalsCommand directive was incorrectly ignored in
		   this situation. bz3574
		 * sshd(8), ssh(1), ssh-keygen(1): remove vestigal support for KRL
		   signatures When the KRL format was originally defined, it included
		   support for signing of KRL objects. However, the code to sign KRLs
		   and verify KRL signatues was never completed in OpenSSH. This
		   release removes the partially-implemented code to verify KRLs.
		   All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
		   KRL files.
		 * All: fix a number of memory leaks and unreachable/harmless integer
		   overflows.
		 * ssh-agent(1), ssh(1): don't truncate strings logged from PKCS#11
		   modules; GHPR406
		 * sshd(8), ssh(1): better validate CASignatureAlgorithms in
		   ssh_config and sshd_config. Previously this directive would accept
		   certificate algorithm names, but these were unusable in practice as
		   OpenSSH does not support CA chains. bz3577
		 * ssh(1): make `ssh -Q CASignatureAlgorithms` only list signature
		   algorithms that are valid for CA signing. Previous behaviour was
		   to list all signing algorithms, including certificate algorithms.
		 * ssh-keyscan(1): gracefully handle systems where rlimits or the
		   maximum number of open files is larger than INT_MAX; bz3581
		 * ssh-keygen(1): fix "no comment" not showing on when running
		   `ssh-keygen -l` on multiple keys where one has a comment and other
		   following keys do not. bz3580
		 * scp(1), sftp(1): adjust ftruncate() logic to handle servers that
		   reorder requests. Previously, if the server reordered requests then
		   the resultant file would be erroneously truncated.
		 * ssh(1): don't incorrectly disable hostname canonicalization when
		   CanonicalizeHostname=yes and ProxyJump was expicitly set to
		   "none". bz3567
		 * scp(1): when copying local->remote, check that the source file
		   exists before opening an SFTP connection to the server. Based on
		   GHPR#370
