>> ??? (Expedited Forwarding), as many networks are configured to allow

will
>> ??? aggressively deprioritise the entire connection if this is
exceeded.
>>

>> ??? to the certificate expiry time plus a short (5 min) grace period.
>>

>>
>> ? * All: remove experimental support for XMSS keys. This was never

>> ??? signature scheme in the near future.
>>
>> ? * ssh(1), sshd(8): deprecate support for IPv4 type-of-service (TOS)
>> ??? keywords in the IPQoS configuration directive.
>>
>> ??? Type of Service (ToS) was deprecated in the late nineties and
>> ??? replaced with the Differentiated Services architecture. Diffserv

>>
>> ??? OpenSSH switched its default IPQoS from ToS to DSCP values in 2018.

'reliability', or
>> ??? 'throughput' will be ignored and instead the system default
QoS

>>
>> ? * ssh-agent(1), sshd(8): move agent listener sockets from /tmp to
>> ??? under ~/.ssh/agent for both ssh-agent(1) and forwarded sockets
>> ??? in sshd(8).
>>
>> ??? This ensures processes that have restricted filesystem access

>> =========================>>
>> New features
>> ------------
>>
>> ? * ssh(1), sshd(8): add SIGINFO handlers to log active channel and
>> ??? session information.
>>
>> ? * sshd(8): when refusing a certificate for user authentication, log
>> ??? enough information to identify the certificate in addition to the
>> ??? reason why it was being denied. Makes debugging certificate
>> ??? authorisation problems a bit easier.
>>
>> ? * ssh(1), ssh-agent(1): support ed25519 keys hosted on PKCS#11
>> ??? tokens.
>>
>> ? * ssh(1): add a ssh_config(5) RefuseConnection option that, when
>> ???? encountered while processing an active section in a
>> ???? configuration terminates ssh(1) with an error message that
>> ???? contains the argument to the option.
>>
>> ???? This may be useful for expressing reminders or warnings in config
>> ???? files, for example:
>>
>> ???? Match host foo
>> ??????????? RefuseConnection "foo is deprecated, use splork
instead"
>>
>> ? * sshd(8): make the X11 display number check relative to
>> ??? X11DisplayOffset. This will allows people to use X11DisplayOffset
>> ??? to configure much higher port ranges if they really want, while
>> ??? not changing the default behaviour.
>>
>> ? * unit tests: the unit test framework now includes some basic
>> ??? benchmarking capabilities. Run with "make
UNITTEST_BENCHMARK=yes"
>> ??? on OpenBSD or "make unit-bench" on Portable OpenSSH.
>>
>> Bugfixes
>> --------
>>
>> ? * sshd(8): fix mistracking of MaxStartups process exits in some
>> ??? situations. At worst, this could cause all MaxStartups slots to
>> ??? fill and sshd to refuse new connections.
>>
>> ? * ssh(1): fix delay on X client startup when ObscureKeystrokeTiming
>> ??? is enabled. bz#3820
>>
>> ? * sshd(8): increase the maximum size of the supported configuration
>> ??? from 256KB to 4MB, which ought to be enough for anybody. Fail
>> ??? early and visibly when this limit is breached. bz3808
>>
>> ? * sftp(1): during sftp uploads, avoid a condition where a failed
>> ??? write could be ignored if a subsequent write succeeded. This is
>> ??? unlikely but technically possible because sftp servers are
>> ??? allowed to reorder requests.
>>
>> ? * sftp(1): avoid a fatal() when sftp tab-completes filenames that
>> ??? share common utf-8 characters that don't encode to a complete
>> ??? codepoint.
>>
>> ? * sshd(8): avoid a race condition when the sshd-auth process exits
>> ??? tha could cause a spurious error message to be logged.
>>
>> ? * sshd(8): log at level INFO when PerSourcePenalties actually
>> ??? blocks access to a source address range. Previously this was
>> ??? logged at level VERBOSE, which hid enforcement actions under
>> ??? default config settings.
>>
>> ? * sshd(8): GssStrictAcceptor was missing from sshd -T output; fix
>>
>> ? * sshd(8): Make the MaxStartups and PerSourceNetBlockSize options
>> ??? first-match-wins as advertised. bz3859
>>
>> ? * ssh(1): fix an incorrect return value check in the local forward
>> ??? cancellation path that would cause failed cancellations not to be
>> ??? logged.
>>
>> ? * sshd(8): make "Match !final" not trigger a 2nd pass
ssh_config
>> ??? parsing pass (unless hostname canonicalisation or a separate
>> ??? "Match final" does). bz3843
>>
>> ? * ssh(1): better debug diagnostics when loading keys. Will now list

>> ??? as making it explicit which keys didn't load.

alias
>> ??? "without-password".? bz#3788
>>
>> ? * ssh(1): make writing known_hosts lines more atomic by writing

>>
>> ??? Usually writes to this file are serialised on the "Are you
sure you

is

>>
>> Portability
>> -----------
>>
>> ? * sshd(8): check the username didn't change during the PAM
>> ??? transactions.
>>
>> ??? PAM modules can change the user during their execution, but
>> ??? this is not supported by sshd(8). If such a case was incorrectly
>> ??? configured by the system administrator, then sshd(8) could end up
>> ??? using a different username to the one authorised by PAM.
>>
>> ? * sshd(8): don't log audit messages with UNKNOWN hostname to
avoid
>> ??? slow DNS lookups in the audit subsystem.
>>
>> ? * All: when making a copy of struct passwd, ensure struct fields are
>> ??? non-NULL. Android libc can return NULL pw_gecos, for example.
>>
>> ? * All: Remove status bits from OpenSSL >=3 version check.
>>
>> ? * sshd(8), ssh(1): Use SSH_TUN_COMPAT_AF on FreeBSD. Otherwise tun
>> ??? forwarding from other OSes fails as soon as the first IPv6 message
>> ??? is sent by the other side (which is usually a Router Solicitation
>> ??? ICMPv6 message which is sent as soon as the interface is up).
>>
>> ? * ssh(1), ssh-agent(8): check for nlist function presence before
>> ??? attenmpting to use it instead of relying on the presence of the
>> ??? nlist.h header.? Mac OS X, in particular has the header, but only
>> ??? has the function in the 32bit libraries.
>>
>> ? * All: fill in missing system header files.
>>
>> ??? Create replacement header files inside openbsd-compat for common
>> ??? headers that are missing on a given platform. Usually these are
>> ??? just empty, but in some cases they'll include the equivalent
file.
>> ??? This avoids having to wrap those includes in '#ifdef
HAVE_FOO_H'
>> ??? and reduces the diff between Portable OpenSSH and OpenBSD.
>>
>> ? * sshd(8): handle futex_time64 properly in seccomp sandbox
>> ??? Previously we only allowed __NR_futex, but some 32-bit systems
>> ??? apparently support __NR_futex_time64. We had support for this
>> ??? in the sandbox, but because of a macro error only __NR_futex was
>> ??? allowlisted.
>>
>> ? * Add contrib/gnome-ssh-askpass4 for GNOME 40+ using the GCR API.
>>
>> ? * sshd(8): let ga_init() fail gracefully if getgrouplist does.
>> ??? Apparently getgrouplist() can fail on OSX when passed a
>> ??? non-existent group name. Other platforms seem to return a group
>> ??? list consisting of the numeric gid passed to the function. bz3848
>>
>> ? * ssh-agent(1): exit 0 from SIGTERM under systemd socket-activation,
>> ??? preventing a graceful shutdown of an agent via systemd from
>> ??? incorrectly marking the service as "failed".
>>
>> ? * build: wrap some autoconf macros in AC_CACHE_CHECK.
>>
>> ??? This allows skipping/overriding the OSSH_CHECK_CFLAG_COMPILE and
>> ??? OSSH_CHECK_CFLAG_LINK macros used to discover supported compiler
>> ??? or linker flags. E.g.
>>
>> ????? $ ./configure ossh_cv_cflag__fzero_call_used_regs_used=no
