    This tests for vwrite() instead of read() in atomicio.c, so
    as to avoid the renaming shenanigans done by SSP of read().
 
    Thanks to riastradh@ for pointing me in the right direction.

    Changes since OpenSSH 10.5
    ==========================
 
    This release contains a number of security fixes, several new
    features and some small bugfixes.
 
    Security
    ========
 
     * sftp(1): more strictly validate paths returned from the server to
       avoid some cases where a server could return paths that could
       manipulate a recursive copy operation into writing outside its
       target directory. Report and patch from Junghoon Cho.
 
     * sshd(8): when GSSAPIAuthentication is in use, only store GSSAPI
       credentials when authentication has succeeded. Avoids a situation
       where credentials from a failed GSSAPIAuthentication attempt may
       persist and be made inappropriately available if another
       authentication subsequently succeeds. Issue report and patch from
       Moritz Theile.
 
     * sshd(8): reset GSSAPIAuthentication before authentication, avoiding
       state from one authentication attempt being confused with that of
       a later attempt. Report and feedback from Moritz Theile.
 
     * sshd(8), ssh(1): disable LZ77 dictionary coder to mitigate the
       side-channel leaks described in "Crossing the Streams: SSH
       Plaintext Recovery via a Common Compression Context in
       Multiplexed Channels" by Fabian B�umer and Marcus Brinkmann,
       preprint https://arxiv.org/abs/2609.07709 (2026)
 
       A chosen-plaintext attack method exists which makes use of
       dictionary-based compression to recover secrets from one channel
       by interacting with the SSH session's shared compression
       dictionary through another channel.
 
       Attacker-controlled input can recognizably reflect into the
       total length of transmitted ciphertexts by virtue of LZ77
       replacing repeated strings with back-references into the SSH
       session's encoder search buffer, which is shared across all
       channels. For this reason, the documentation already recommended
       against enabling compression for connections that share trusted
       and untrusted traffic.
 
       This change will reduce the effectiveness of the Compression
       option. Users are encouraged to use application-level compression
       over the SSH protocol where possible, as this will typically be
       more effective and will be completely immune to this type of
       attack.
 
     * ssh(1): disallow '$' and '\' characters in usernames entered on
       the command-line to avoid usernames from untrusted sources
       yielding injection in shell context via ProxyCommand, Match exec,
       etc. Usernames specified via the configuration files are not
       subject this this control. Reported by SecBuddyF KeenLab Tencent
       (CodeBuddy Security)
 
       We continue to recommend against directly exposing ssh(1) and
       other tools' command-lines to untrusted input. Mitigations such
       as this can not be absolute given the variety of shells and user
       configurations in use.
 
     * ssh-keygen(1): correct handling of Daylight Saving Time when
       converting dates. Previous handling could cause errors of
       up to +/- 1 hour (unless you are in the Antarctica/Troll
       timezone, where the error could be +/- 2 hours). These errors
       could result in creation of certificates with incorrect expiry
       times. bz4004; from Khush Patel
 
     * sshd(8), ssh(1): ensure that compressed payloads don't inflate
       past the maximum supported packet length. Reported by Oleh Konko.
 
     * sshd(8): fully honor the authorized_keys "restrict" keyword,
       which was not being properly applied to tunnel forwarding
       (PermitTunnel, disabled by default). This is a separate problem
       to the one fixed in openssh-10.5.
 
     * sshd(8): correctly handle some options that accept "none". Some
       options, including AuthorizedPrincipalsFile, were documented as
       accepting "none" as a way to disable them; however, when
       overridden by an sshd_config(5) Match keyword, this argument was
       being incorrectly interpreted as a literal file.
       With Chris Rohlf in collaboration with Claude and Anthropic Research
 
     * sshd(8): On OS X SDK >= 27, sandboxing is no longer supported
       as the API we depended upon has been removed and no obvious
       alternative provided.
 
     * sshd(8): on platforms that do not support file descriptor passing
       and that require root for PTY allocation, the post-authentication
       sshd-session process retains root privilege, whereas on other
       platforms this process runs with the privilege of the logged-in
       user. When sshd-session was run with elevated privilege, it could
       perform certain actions as root and circumvent controls that
       would normally have applied to the user, such as making unix
       domain socket connections or binding (via -R forwarding) to low-
       numbered TCP ports.
 
       For this reason, this release disables the GatewayPorts and
       StreamLocalForwarding options and support for these (few)
       platforms will be removed in future if no alternatives to
       requiring privilege in the post-authentication process are found.
       Affected platforms include QNX 6, SCO OpenServer 5 and builds
       that were made with the --disable-fd-passing configure option.
 
       This problem was reported separately by sn0x-sharma and by Dark
       River.
 
    New features
    ------------
 
     * All: enable hybrid post-quantum ssh-mldsa44-ed25519 signature
       algorithm. Note that this no longer uses the "@openssh.com"
       vendor extension suffix that the previous experimental
       implementation used. Keys generated with the previous experimental
       support must be regenerated and/or removed.
 
     * sshd(8): Add the WarnWeakCrypto option to sshd_config(5). This
       option was previously available for the client only. This option
       is enabled by default and will log when the client uses a key
       agreement scheme that is not post-quantum safe.
 
     * ssh-keygen(1), ssh-add(1): preserve user-verification (PIN or
       biometric) requirement for resident keys loaded from a FIDO
       token, by checking the credential's credProtect policy.
       GHPR701 from Savely Krasovsky
 
     * ssh(1): include local and remote version strings in the ~I
       connection information display.
 
     * ssh-add(1): add a -P flag to skip PIN entry for FIDO and PKCS#11
       tokens that do not require it.
 
     * sftp(1): add '-p' flag for mkdir/lmkdir to create directories as
       required. This flag has similar ergonomics to mkdir(1), and
       previously-existing directories do not cause an error.
 
     * ssh-keygen(1): add a "hexdump" key export mode that dumps the SSH
       wire-formatted key blob in hex format. Useful when writing
       documentation, tests, etc. E.g. `ssh-keygen -em hexdump -f /key`
 
     * ssh(1), sshd(8): ChannelTimeout now accepts timeouts with
       fractional seconds.
 
     * sshd(8): allow specification of the location of $SSH_AUTH_SOCK
       used for agent forwarding using a new AgentSocketPath option.
       This supports both using a user-specific path, such as the
       default of a subdirectory of $HOME ("user:.ssh/agent"), and
       the previous approach of allowing agent forwarding sockets to be
       located in a shared directory (e.g. "shared:/tmp"). Sockets
       created in shared directories will be created inside a
       subdirectory with a randomised name. bz3860
 
     * ssh-agent(1): allow specification of agent socket directories
       using a -A flag. It accepts "user:" and "shared:" directory
       styles similar to the sshd AgentSocketPath option.
 
     * sshd(8): account for public key authentication "key ok" tests
       separately to auth attempts. Add a `PubkeyOptions max-pk-ok:nnnn`
       option to allow a number of PK_OK tests (asking whether the
       server might accept a given public key) that do not count against
       MaxAuthTries, defaulting to 6 attempts. After these attempts are
       exhausted, further attempts count as failed authentications
       against MaxAuthTries. Practically, this allows more keys on disk
       or held in ssh-agent to be checked for use before the server
       disconnects.
 
     * ssh(1), sshd(8): extend the existing TCPKeepAlive option to also
       support setting keepalives on sockets created for forwarding
       connections. Previously this option controlled keepalives on the
       connection socket only. TCPKeepAlive "yes" or "transport" enables
       keepalives on the connection socket. "TCPKeepAlive all" additionally
       enables them for forwarding sockets. bz3921
 
    Bugfixes
    --------
 
     * sshd(8), ssh(1): fix configuration matching on more Turkic
       languages which have disjoint dotted and dotless i/I characters,
       specifically Azerbaijani and Crimean Tatar. bz3991
 
     * ssh(1), sshd(8): don't attempt to set TCP_NODELAY on non-IP/IPv6
       sockets. Eliminates some noise in debug logs.
 
     * ssh(1): fix case for ssh -G option output; bz4005
 
     * ssh(1), sshd(8): Fix ChannelTimeout specificity; previously a
       more specific channel type (e.g. "session:shell") could clobber
       a user-specified ChannelTimeout if it was less specific (e.g.
       "session").  Also, in some cases, the debug messages were
       printing 0 instead of the effective timeout. bz3994
 
     * sftp(1): avoid NULL dereference crash in some circumstances when
       a server fails a stat/lstat operation. GHPR707
 
     * sshd(8): close a race condition where a SIGTERM/SIGQUIT would be
       ignored if it was received by the server while it was processing a
       SIGHUP restart request. bz3981
 
     * sshd(8), ssh(1): check key and CA signature types during key
       parsing against allowlists (PubkeyAcceptedAlgorithms, etc) as
       early as possible. This reduces the attack surface presented by
       disabled algorithms. Suggested by and with extensive feedback
       from Chris Rohlf in collaboration with Claude and Anthropic
       Research.
 
     * All: switch the fallback implementation of the ed25519 signature
       algorithm used when libcrypto is disabled from SUPERCOP ed25519
       to libsodium. The libsodium implementation includes a number of
       strictness checks over the original reference implementation we
       have used to this point and a more ergonomic API.
 
     * ssh-add(1), ssh(1), ssh-keygen(1): fix spin on password entry when
       the program attempting to read a password was started in a
       background process group, with no TTY and with certain signals
       ignored. bz3995
 
     * scp(1): disallow nul byte in received scp -O filename. This was
       not reachable in normal operation. Reported by Chua Wei Xun.
 
     * ssh-keygen(1), ssh(1), sshd(8): implement a maximum number of KDF
       rounds that will be accepted when writing an OpenSSH-format
       private key or when loading one. This limit is set quite high
       (1M), but ensures that a service that is passed a bad key with a
       ridiculously high number of rounds will eventually complete
       parsing it.
 
     * ssh-keygen(1): bump the default number of KDF rounds from 24 to
       32 (this is a linear increase, not like bcrypt(3) which is
       exponential).
 
     * ssh(1): make StreamLocalBindMask properly respect Host/Match
       blocks and make it first-match-wins as documented. bz4013
 
     * sshd(8): make StreamLocalBindMask properly first-match-wins.
 
    Portability
    -----------
 
     * All: remove the NetBSD BROKEN_READ_COMPARISON workaround. This
       appears to be no longer required and caused pre-auth CPU spinning.
 
     * sshd(8): don't link sshd against libselinux when SELinux support
       is enabled (note: this library is still linked for the sshd-auth
       and sshd-session helper binaries).
 
     * sshd(8): allow madvise(..., MADV_DONTNEED_LOCKED) in the seccomp
       sandbox; needed by GrapheneOS' hardened allocator. bz4001
 
     * sshd(8): restrict mremap(2) flags accepted by the seccomp
       sandbox. Only MREMAP_MAYMOVE is now accepted as other flags may
       have some utility in attack chains. Reported by: Mohammad Hossein
       Abedini.
 
     * sshd(8): allow PAMServiceName in Match (regressed in 10.4).
       During the refactor of server option parsing, the ability to set
       PAMServiceName in Match blocks was accidentally disabled.
 
     * sshd(8): the --disable-fd-passing configure option has been
       removed.
