Summary: Secure Shell Client and Server (Remote Login Program)
SSH (Secure Shell) is a program for logging into and executing commands
on a remote machine. It replaces rsh (rlogin and rsh) and
provides secure encrypted communication between two untrusted
hosts over an insecure network.

xorg-x11 (X Window System) connections and arbitrary TCP/IP ports can
also be forwarded over the secure channel.

This is a dummy package that pulls in both the client and server

  - update to 8.4p1:
    * ssh-agent(1): restrict ssh-agent from signing web challenges for
    FIDO/U2F keys.
    * ssh-keygen(1): Enable FIDO 2.1 credProtect extension when generating
    a FIDO resident key.
    * ssh(1), ssh-keygen(1): support for FIDO keys that require a PIN for
    each use. These keys may be generated using ssh-keygen using a new
    "verify-required" option. When a PIN-required key is used, the user
    will be prompted for a PIN to complete the signature operation.
    New Features
    - -----------
    * sshd(8): authorized_keys now supports a new "verify-required"
    option to require FIDO signatures assert that the token verified
    that the user was present before making the signature. The FIDO
    protocol supports multiple methods for user-verification, but
    currently OpenSSH only supports PIN verification.
    * sshd(8), ssh-keygen(1): add support for verifying FIDO webauthn
    signatures. Webauthn is a standard for using FIDO keys in web
    browsers. These signatures are a slightly different format to plain
    FIDO signatures and thus require explicit support.
    * ssh(1): allow some keywords to expand shell-style ${ENV}
    environment variables. The supported keywords are CertificateFile,
    ControlPath, IdentityAgent and IdentityFile, plus LocalForward and
    RemoteForward when used for Unix domain socket paths. bz#3140
    * ssh(1), ssh-agent(1): allow some additional control over the use of
    ssh-askpass via a new $SSH_ASKPASS_REQUIRE environment variable,
    including forcibly enabling and disabling its use. bz#69
    * ssh(1): allow ssh_config(5)'s AddKeysToAgent keyword accept a time
    limit for keys in addition to its current flag options. Time-
    limited keys will automatically be removed from ssh-agent after
    their expiry time has passed.
    * scp(1), sftp(1): allow the -A flag to explicitly enable agent
    forwarding in scp and sftp. The default remains to not forward an
    agent, even when ssh_config enables it.
    * ssh(1): add a '%k' TOKEN that expands to the effective HostKey of
    the destination. This allows, e.g., keeping host keys in individual
    files using "UserKnownHostsFile ~/.ssh/known_hosts.d/%k". bz#1654
    * ssh(1): add %-TOKEN, environment variable and tilde expansion to
    the UserKnownHostsFile directive, allowing the path to be
    completed by the configuration (e.g. bz#1654)
    * ssh-keygen(1): allow "ssh-add -d -" to read keys to be deleted
    from stdin. bz#3180
    * sshd(8): improve logging for MaxStartups connection throttling.
    sshd will now log when it starts and stops throttling and periodically
    while in this state. bz#3055
    - -------
    * ssh(1), ssh-keygen(1): better support for multiple attached FIDO
    tokens. In cases where OpenSSH cannot unambiguously determine which
    token to direct a request to, the user is now required to select a
    token by touching it. In cases of operations that require a PIN to
    be verified, this avoids sending the wrong PIN to the wrong token
    and incrementing the token's PIN failure counter (tokens
    effectively erase their keys after too many PIN failures).
    * sshd(8): fix Include before Match in sshd_config; bz#3122
    * ssh(1): close stdin/out/error when forking after authentication
    completes ("ssh -f ...") bz#3137
    * ssh(1), sshd(8): limit the amount of channel input data buffered,
    avoiding peers that advertise large windows but are slow to read
    from causing high memory consumption.
    * ssh-agent(1): handle multiple requests sent in a single write() to
    the agent.
    * sshd(8): allow sshd_config longer than 256k
    * sshd(8): avoid spurious "Unable to load host key" message when sshd
    load a private key but no public counterpart
    * ssh(1): prefer the default hostkey algorithm list whenever we have
    a hostkey that matches its best-preference algorithm.
    * sshd(1): when ordering the hostkey algorithms to request from a
    server, prefer certificate types if the known_hosts files contain a key
    marked as a @cert-authority; bz#3157
    * ssh(1): perform host key fingerprint comparisons for the "Are you
    sure you want to continue connecting (yes/no/[fingerprint])?"
    prompt with case sensitivity.
    * sshd(8): ensure that address/masklen mismatches in sshd_config
    yield fatal errors at daemon start time rather than later when
    they are evaluated.
    * ssh-keygen(1): ensure that certificate extensions are lexically
    sorted. Previously if the user specified a custom extension then
    the everything would be in order except the custom ones. bz#3198
    * ssh(1): also compare username when checking for JumpHost loops.
    * ssh-keygen(1): preserve group/world read permission on known_hosts
    files across runs of "ssh-keygen -Rf /path". The old behaviour was
    to remove all rights for group/other. bz#3146
    * ssh-keygen(1): Mention the [-a rounds] flag in the ssh-keygen
    manual page and usage().
    * sshd(8): explicitly construct path to ~/.ssh/rc rather than
    relying on it being relative to the current directory, so that it
    can still be found if the shell startup changes its directory.
    * sshd(8): when redirecting sshd's log output to a file, undo this
    redirection after the session child process is forked(). Fixes
    missing log messages when using this feature under some
    * sshd(8): start ClientAliveInterval bookkeeping before first pass
    through select() loop; fixed theoretical case where busy sshd may
    ignore timeouts from client.
    * ssh(1): only reset the ServerAliveInterval check when we receive
    traffic from the server and ignore traffic from a port forwarding
    client, preventing a client from keeping a connection alive when
    it should be terminated. bz#2265
    * ssh-keygen(1): avoid spurious error message when ssh-keygen
    creates files outside ~/.ssh
    * sftp-client(1): fix off-by-one error that caused sftp downloads to
    make one more concurrent request that desired. This prevented using
    sftp(1) in unpipelined request/response mode, which is useful when
    debugging. bz#3054
    * ssh(1), sshd(8): handle EINTR in waitfd() and timeout_connect()
    helpers. bz#3071
    * ssh(1), ssh-keygen(1): defer creation of ~/.ssh until we attempt to
    write to it so we don't leave an empty .ssh directory when it's not
    needed. bz#3156
    * ssh(1), sshd(8): fix multiplier when parsing time specifications
    when handling seconds after other units. bz#3171
* Fri Jan 08 2021 Hans Petter Jansson <>
  - Update openssh-8.1p1-audit.patch (bsc#1180501). This fixes
    occasional crashes on connection termination caused by accessing
    freed memory.
* Fri Nov 27 2020 Thorsten Kukuk <>
  - Support /usr/etc/pam.d
* Wed Nov 11 2020 Hans Petter Jansson <>
  - Fix build breakage caused by missing security key objects:
    + Modify openssh-7.7p1-cavstest-ctr.patch.
    + Modify openssh-7.7p1-cavstest-kdf.patch.
    + Add openssh-link-with-sk.patch.
* Wed Nov 11 2020 Hans Petter Jansson <>
  - Add openssh-fips-ensure-approved-moduli.patch (bsc#1177939).
    This ensures only approved DH parameters are used in FIPS mode.
* Wed Nov 11 2020 Hans Petter Jansson <>
  - Add openssh-8.1p1-ed25519-use-openssl-rng.patch (bsc#1173799).
    This uses OpenSSL's RAND_bytes() directly instead of the internal
    ChaCha20-based implementation to obtain random bytes for Ed25519
    curve computations. This is required for FIPS compliance.
* Thu Oct 08 2020 Hans Petter Jansson <>
  - Work around %service_add_post disabling sshd on upgrade with
    package name change (bsc#1177039).
* Fri Sep 25 2020 Dominique Leuenberger <>
  - Fix fillup-template usage:
    + %post server needs to reference ssh (not sshd), which matches
      the sysconfig.ssh file name the package ships.
    + %post client does not need any fillup_ calls, as there is no
      client-relevant sysconfig file present. The naming of the
      sysconfig file (ssh instead of sshd) is unfortunate.
* Fri Sep 25 2020 Franck Bui <>
  - Use of DISABLE_RESTART_ON_UPDATE is deprecated.
    Replace it with %service_del_postun_without_restart
* Thu Sep 17 2020 Jan Engelhardt <>
  - Move some Requires to the right subpackage.
  - Avoid ">&" bashism in %post.
  - Upgrade some old specfile constructs/macros and drop unnecessary
  - Trim descriptions and straighten out the grammar.
* Thu Sep 10 2020 Hans Petter Jansson <>
  - Split openssh package into openssh, openssh-common,
    openssh-server and openssh-clients. This allows for the ssh
    clients to be installed without the server component
* Fri Jun 05 2020 Hans Petter Jansson <>
  - Version update to 8.3p1:
    = Potentially-incompatible changes
    * sftp(1): reject an argument of "-1" in the same way as ssh(1) and
      scp(1) do instead of accepting and silently ignoring it.
    = New features
    * sshd(8): make IgnoreRhosts a tri-state option: "yes" to ignore
      rhosts/shosts, "no" allow rhosts/shosts or (new) "shosts-only"
      to allow .shosts files but not .rhosts.
    * sshd(8): allow the IgnoreRhosts directive to appear anywhere in a
      sshd_config, not just before any Match blocks.
    * ssh(1): add %TOKEN percent expansion for the LocalFoward and
      RemoteForward keywords when used for Unix domain socket forwarding.
    * all: allow loading public keys from the unencrypted envelope of a
      private key file if no corresponding public key file is present.
    * ssh(1), sshd(8): prefer to use chacha20 from libcrypto where
      possible instead of the (slower) portable C implementation included
      in OpenSSH.
    * ssh-keygen(1): add ability to dump the contents of a binary key
      revocation list via "ssh-keygen -lQf /path".
  - Additional changes from 8.2p1 release:
    = Potentially-incompatible changes
    * ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
      (RSA/SHA1) algorithm from those accepted for certificate signatures
      (i.e. the client and server CASignatureAlgorithms option) and will
      use the rsa-sha2-512 signature algorithm by default when the
      ssh-keygen(1) CA signs new certificates.
    * ssh(1), sshd(8): this release removes diffie-hellman-group14-sha1
      from the default key exchange proposal for both the client and
    * ssh-keygen(1): the command-line options related to the generation
      and screening of safe prime numbers used by the
      diffie-hellman-group-exchange-* key exchange algorithms have
      changed. Most options have been folded under the -O flag.
    * sshd(8): the sshd listener process title visible to ps(1) has
      changed to include information about the number of connections that
      are currently attempting authentication and the limits configured
      by MaxStartups.
    * ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F
      support to provide address-space isolation for token middleware
      libraries (including the internal one). It needs to be installed
      in the expected path, typically under /usr/libexec or similar.
    = New features
    * This release adds support for FIDO/U2F hardware authenticators to
      OpenSSH. U2F/FIDO are open standards for inexpensive two-factor
      authentication hardware that are widely used for website
      authentication.  In OpenSSH FIDO devices are supported by new public
      key types "ecdsa-sk" and "ed25519-sk", along with corresponding
      certificate types.
    * sshd(8): add an Include sshd_config keyword that allows including
      additional configuration files via glob(3) patterns.
    * ssh(1)/sshd(8): make the LE (low effort) DSCP code point available
      via the IPQoS directive.
    * ssh(1): when AddKeysToAgent=yes is set and the key contains no
      comment, add the key to the agent with the key's path as the
    * ssh-keygen(1), ssh-agent(1): expose PKCS#11 key labels and X.509
      subjects as key comments, rather than simply listing the PKCS#11
      provider library path.
    * ssh-keygen(1): allow PEM export of DSA and ECDSA keys.
    * ssh(1), sshd(8): make zlib compile-time optional, available via the ZLIB flag on OpenBSD or via the --with-zlib configure
      option for OpenSSH portable.
    * sshd(8): when clients get denied by MaxStartups, send a
      notification prior to the SSH2 protocol banner according to
      RFC4253 section 4.2.
    * ssh(1), ssh-agent(1): when invoking the $SSH_ASKPASS prompt
      program, pass a hint to the program to describe the type of
      desired prompt.  The possible values are "confirm" (indicating
      that a yes/no confirmation dialog with no text entry should be
      shown), "none" (to indicate an informational message only), or
      blank for the original ssh-askpass behaviour of requesting a
    * ssh(1): allow forwarding a different agent socket to the path
      specified by $SSH_AUTH_SOCK, by extending the existing ForwardAgent
      option to accepting an explicit path or the name of an environment
      variable in addition to yes/no.
    * ssh-keygen(1): add a new signature operations "find-principals" to
      look up the principal associated with a signature from an allowed-
      signers file.
    * sshd(8): expose the number of currently-authenticating connections
      along with the MaxStartups limit in the process title visible to

  - Make sure ssh-keygen runs if SSHD_AUTO_KEYGEN variable is unset
    or contains an unrecognized value (bsc#1157176).
* Fri Nov 08 2019 Cristian Rodríguez <>
  - Add openssh-8.1p1-seccomp-clock_nanosleep.patch, allow clock_nanosleep

* Thu Oct 17 2019 Hans Petter Jansson <>
  - Update openssh-7.7p1-audit.patch to fix crash (bsc#1152730). Fix
    by Enzo Matsumiya ( This was integrated in
    a separate code stream merged with the Oct. 10 update; the patch
    was also rebased and renamed to openssh-8.1p1-audit.patch.
* Mon Oct 14 2019 Hans Petter Jansson <>
  - Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574).
    This attempts to preserve the permissions of any existing
    known_hosts file when modified by ssh-keygen (for instance,
    with -R).
  - Added openssh-7.9p1-revert-new-qos-defaults.patch, which reverts
    an upstream commit that caused compatibility issues with other
    software (bsc#1136402).
* Mon Oct 14 2019 Hans Petter Jansson <>
  - Run 'ssh-keygen -A' on startup only if SSHD_AUTO_KEYGEN="yes"
    in /etc/sysconfig/ssh. This is set to "yes" by default, but
    can be changed by the system administrator (bsc#1139089).
* Mon Oct 14 2019 Hans Petter Jansson <>
  - Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574).
    This attempts to preserve the permissions of any existing
    known_hosts file when modified by ssh-keygen (for instance,
    with -R).
* Thu Oct 10 2019 Hans Petter Jansson <>
  - Version update to 8.1p1:
    * ssh-keygen(1): when acting as a CA and signing certificates with
      an RSA key, default to using the rsa-sha2-512 signature algorithm.
      Certificates signed by RSA keys will therefore be incompatible
      with OpenSSH versions prior to 7.2 unless the default is
      overridden (using "ssh-keygen -t ssh-rsa -s ...").
    * ssh(1): Allow %n to be expanded in ProxyCommand strings
    * ssh(1), sshd(8): Allow prepending a list of algorithms to the
      default set by starting the list with the '^' character, E.g.
      "HostKeyAlgorithms ^ssh-ed25519"
    * ssh-keygen(1): add an experimental lightweight signature and
      verification ability. Signatures may be made using regular ssh keys
      held on disk or stored in a ssh-agent and verified against an
      authorized_keys-like list of allowed keys. Signatures embed a
      namespace that prevents confusion and attacks between different
      usage domains (e.g. files vs email).
    * ssh-keygen(1): print key comment when extracting public key from a
      private key.
    * ssh-keygen(1): accept the verbose flag when searching for host keys
      in known hosts (i.e. "ssh-keygen -vF host") to print the matching
      host's random-art signature too.
    * All: support PKCS8 as an optional format for storage of private
      keys to disk.  The OpenSSH native key format remains the default,
      but PKCS8 is a superior format to PEM if interoperability with
      non-OpenSSH software is required, as it may use a less insecure
      key derivation function than PEM's.
  - Additional changes from 8.0p1 release:
    * scp(1): Add "-T" flag to disable client-side filtering of
      server file list.
    * sshd(8): Remove support for obsolete "host/port" syntax.
    * ssh(1), ssh-agent(1), ssh-add(1): Add support for ECDSA keys in
      PKCS#11 tokens.
    * ssh(1), sshd(8): Add experimental quantum-computing resistant
      key exchange method, based on a combination of Streamlined NTRU
      Prime 4591^761 and X25519.
    * ssh-keygen(1): Increase the default RSA key size to 3072 bits,
      following NIST Special Publication 800-57's guidance for a
      128-bit equivalent symmetric security level.
    * ssh(1): Allow "PKCS11Provider=none" to override later instances of
      the PKCS11Provider directive in ssh_config,
    * sshd(8): Add a log message for situations where a connection is
      dropped for attempting to run a command but a sshd_config
      ForceCommand=internal-sftp restriction is in effect.
    * ssh(1): When prompting whether to record a new host key, accept
      the key fingerprint as a synonym for "yes". This allows the user
      to paste a fingerprint obtained out of band at the prompt and
      have the client do the comparison for you.
    * ssh-keygen(1): When signing multiple certificates on a single
      command-line invocation, allow automatically incrementing the
      certificate serial number.
    * scp(1), sftp(1): Accept -J option as an alias to ProxyJump on
      the scp and sftp command-lines.
    * ssh-agent(1), ssh-pkcs11-helper(8), ssh-add(1): Accept "-v"
      command-line flags to increase the verbosity of output; pass
      verbose flags though to subprocesses, such as ssh-pkcs11-helper
      started from ssh-agent.
    * ssh-add(1): Add a "-T" option to allowing testing whether keys in
      an agent are usable by performing a signature and a verification.
    * sftp-server(8): Add a "" protocol extension
      that replicates the functionality of the existing SSH2_FXP_SETSTAT
      operation but does not follow symlinks.
    * sftp(1): Add "-h" flag to chown/chgrp/chmod commands to request
      they do not follow symlinks.
    * sshd(8): Expose $SSH_CONNECTION in the PAM environment. This makes
      the connection 4-tuple available to PAM modules that wish to use
      it in decision-making.
    * sshd(8): Add a ssh_config "Match final" predicate Matches in same
      pass as "Match canonical" but doesn't require hostname
      canonicalisation be enabled.
    * sftp(1): Support a prefix of '@' to suppress echo of sftp batch
    * ssh-keygen(1): When printing certificate contents using
      "ssh-keygen -Lf /path/certificate", include the algorithm that
      the CA used to sign the cert.

    * ssh(1), sshd(8): the setting of the new CASignatureAlgorithms
      option (see below) bans the use of DSA keys as certificate
    * sshd(8): the authentication success/failure log message has
      changed format slightly. It now includes the certificate
      fingerprint (previously it included only key ID and CA key
    * ssh(1), sshd(8): allow most port numbers to be specified using
      service names from getservbyname(3) (typically /etc/services).
    * sshd(8): support signalling sessions via the SSH protocol.
      A limited subset of signals is supported and only for login or
      command sessions (i.e. not subsystems) that were not subject to
      a forced command via authorized_keys or sshd_config. bz#1424
    * ssh(1): support "ssh -Q sig" to list supported signature options.
      Also "ssh -Q help" to show the full set of supported queries.
    * ssh(1), sshd(8): add a CASignatureAlgorithms option for the
      client and server configs to allow control over which signature
      formats are allowed for CAs to sign certificates. For example,
      this allows banning CAs that sign certificates using the RSA-SHA1
      signature algorithm.
    * sshd(8), ssh-keygen(1): allow key revocation lists (KRLs) to
      revoke keys specified by SHA256 hash.
    * ssh-keygen(1): allow creation of key revocation lists directly
      from base64-encoded SHA256 fingerprints. This supports revoking
      keys using only the information contained in sshd(8)
      authentication log messages.

* Mon May 21 2018
  - Upgrade to 7.7p1 (bsc#1094068)
    Most important changes (more details below):
    * Drop compatibility support for pre-2001 SSH implementations
    * sshd(1) does not load DSA keys by default
    Distilled upstream log:
    - --- Potentially-incompatible changes
    * ssh(1)/sshd(8): Drop compatibility support for some very old
      SSH implementations, including <=2.* and OpenSSH <=
      3.*.  These versions were all released in or before 2001 and
      predate the final SSH RFCs. The support in question isn't
      necessary for RFC-compliant SSH implementations.
    - --- New Features
    * experimental support for PQC XMSS keys (Extended Hash-Based
      Signatures), not compiled in by default.
    * sshd(8): Add a "rdomain" criteria for the sshd_config Match
      keyword to allow conditional configuration that depends on
      which routing domain a connection was received on (currently
      supported on OpenBSD and Linux).
    * sshd_config(5): Add an optional rdomain qualifier to the
      ListenAddress directive to allow listening on different
      routing domains. This is supported only on OpenBSD and Linux
      at present.
    * sshd_config(5): Add RDomain directive to allow the
      authenticated session to be placed in an explicit routing
      domain. This is only supported on OpenBSD at present.
    * sshd(8): Add "expiry-time" option for authorized_keys files
      to allow for expiring keys.
    * ssh(1): Add a BindInterface option to allow binding the
      outgoing connection to an interface's address (basically a
      more usable BindAddress)
    * ssh(1): Expose device allocated for tun/tap forwarding via a
      new %T expansion for LocalCommand. This allows LocalCommand
      to be %used to prepare the interface.
    * sshd(8): Expose the device allocated for tun/tap forwarding
      via a new SSH_TUNNEL environment variable. This allows
      automatic setup of the interface and surrounding network
      configuration automatically on the server.
    * ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp,
      e.g.  ssh://user@host or sftp://user@host/path.  Additional
      connection parameters that use deporecated MD5 are not
    * ssh-keygen(1): Allow certificate validity intervals that
      specify only a start or stop time (instead of both or
    * sftp(1): Allow "cd" and "lcd" commands with no explicit path
      argument. lcd will change to the local user's home directory
      as usual. cd will change to the starting directory for
      session (because the protocol offers no way to obtain the
      remote user's home directory). bz#2760
    * sshd(8): When doing a config test with sshd -T, only require
      the attributes that are actually used in Match criteria
      rather than (an incomplete list of) all criteria.
    - --- Bugfixes
    * ssh(1)/sshd(8): More strictly check signature types during
      key exchange against what was negotiated. Prevents downgrade
      of RSA signatures made with SHA-256/512 to SHA-1.
    * sshd(8): Fix support for client that advertise a protocol
      version of "1.99" (indicating that they are prepared to
      accept both SSHv1 and SSHv2). This was broken in OpenSSH 7.6
      during the removal of SSHv1 support. bz#2810
    * ssh(1): Warn when the agent returns a ssh-rsa (SHA1)
      signature when a rsa-sha2-256/512 signature was requested.
      This condition is possible when an old or non-OpenSSH agent
      is in use. bz#2799
    * ssh-agent(1): Fix regression introduced in 7.6 that caused
      ssh-agent to fatally exit if presented an invalid signature
      request message.
    * sshd_config(5): Accept yes/no flag options
      case-insensitively, as has been the case in ssh_config(5) for
      a long time. bz#2664
    * ssh(1): Improve error reporting for failures during
      connection.  Under some circumstances misleading errors were
      being shown. bz#2814
    * ssh-keyscan(1): Add -D option to allow printing of results
      directly in SSHFP format. bz#2821
    * regress tests: fix PuTTY interop test broken in last
      release's SSHv1 removal. bz#2823
    * ssh(1): Compatibility fix for some servers that erroneously
      drop the connection when the IUTF8 (RFC8160) option is sent.
    * scp(1): Disable RemoteCommand and RequestTTY in the ssh
      session started by scp (sftp was already doing this.)
    * ssh-keygen(1): Refuse to create a certificate with an
      unusable number of principals.
    * ssh-keygen(1): Fatally exit if ssh-keygen is unable to write
      all the public key during key generation. Previously it would
      silently ignore errors writing the comment and terminating
    * ssh(1): Do not modify hostname arguments that are addresses
      by automatically forcing them to lower-case. Instead
      canonicalise them to resolve ambiguities (e.g. ::0001 => ::1)
      before they are matched against known_hosts. bz#2763
    * ssh(1): Don't accept junk after "yes" or "no" responses to
      hostkey prompts. bz#2803
    * sftp(1): Have sftp print a warning about shell cleanliness
      when decoding the first packet fails, which is usually caused
      by shells polluting stdout of non-interactive startups.
    * ssh(1)/sshd(8): Switch timers in packet code from using
      wall-clock time to monotonic time, allowing the packet layer
      to better function over a clock step and avoiding possible
      integer overflows during steps.
    * Numerous manual page fixes and improvements.
* Wed May 02 2018
  - Use TIRPC on suse_version >= 1500: sunrpc is deprecated and
    should be replaced by TIRPC.

    with new %_fillupdir macro (boo#1069468)
  - tighten configuration access rights
* Thu Jan 11 2018
  - Update to vanilla 7.6p1
    Most important changes (more details below):
    * complete removal of the ancient SSHv1 protocol
    * sshd(8) cannot run without privilege separation
    * removal of suport for arcfourm blowfish and CAST ciphers
      and RIPE-MD160 HMAC
    * refuse RSA keys shorter than 1024 bits
    Distilled upstream log:
  - OpenSSH 7.3
    - --- Security
    * sshd(8): Mitigate a potential denial-of-service attack
      against the system's crypt(3) function via sshd(8). An
      attacker could send very long passwords that would cause
      excessive CPU use in crypt(3). sshd(8) now refuses to accept
      password authentication requests of length greater than 1024
      characters. Independently reported by Tomas Kuthan (Oracle),
      Andres Rojas and Javier Nieto.
    * sshd(8): Mitigate timing differences in password
      authentication that could be used to discern valid from
      invalid account names when long passwords were sent and
      particular password hashing algorithms are in use on the
      server. CVE-2016-6210, reported by EddieEzra.Harari at
    * ssh(1), sshd(8): Fix observable timing weakness in the CBC
      padding oracle countermeasures. Reported by Jean Paul
      Degabriele, Kenny Paterson, Torben Hansen and Martin
      Albrecht. Note that CBC ciphers are disabled by default and
      only included for legacy compatibility.
    * ssh(1), sshd(8): Improve operation ordering of MAC
      verification for Encrypt-then-MAC (EtM) mode transport MAC
      algorithms to verify the MAC before decrypting any
      ciphertext. This removes the possibility of timing
      differences leaking facts about the plaintext, though no such
      leakage has been observed.  Reported by Jean Paul Degabriele,
      Kenny Paterson, Torben Hansen and Martin Albrecht.
    * sshd(8): (portable only) Ignore PAM environment vars when
      UseLogin=yes. If PAM is configured to read user-specified
      environment variables and UseLogin=yes in sshd_config, then a
      hostile local user may attack /bin/login via LD_PRELOAD or
      similar environment variables set via PAM. CVE-2015-8325,
      found by Shayan Sadigh.
    - --- New Features
    * ssh(1): Add a ProxyJump option and corresponding -J
      command-line flag to allow simplified indirection through a
      one or more SSH bastions or "jump hosts".
    * ssh(1): Add an IdentityAgent option to allow specifying
      specific agent sockets instead of accepting one from the
    * ssh(1): Allow ExitOnForwardFailure and ClearAllForwardings to
      be optionally overridden when using ssh -W. bz#2577
    * ssh(1), sshd(8): Implement support for the IUTF8 terminal
      mode as per draft-sgtatham-secsh-iutf8-00.
    * ssh(1), sshd(8): Add support for additional fixed
      Diffie-Hellman 2K, 4K and 8K groups from
    * ssh-keygen(1), ssh(1), sshd(8): support SHA256 and SHA512 RSA
      signatures in certificates;
    * ssh(1): Add an Include directive for ssh_config(5) files.
    * ssh(1): Permit UTF-8 characters in pre-authentication banners
      sent from the server. bz#2058
    - --- Bugfixes
    * ssh(1), sshd(8): Reduce the syslog level of some relatively
      common protocol events from LOG_CRIT. bz#2585
    * sshd(8): Refuse AuthenticationMethods="" in configurations
      and accept AuthenticationMethods=any for the default
      behaviour of not requiring multiple authentication. bz#2398
    * sshd(8): Remove obsolete and misleading "POSSIBLE BREAK-IN
      ATTEMPT!" message when forward and reverse DNS don't match.
    * ssh(1): Close ControlPersist background process stderr except
      in debug mode or when logging to syslog. bz#1988
    * misc: Make PROTOCOL description for channel open messages match
      deployed code. bz#2529
    * ssh(1): Deduplicate LocalForward and RemoteForward entries to
      fix failures when both ExitOnForwardFailure and hostname
      canonicalisation are enabled. bz#2562
    * sshd(8): Remove fallback from moduli to obsolete "primes"
      file that was deprecated in 2001. bz#2559.
    * sshd_config(5): Correct description of UseDNS: it affects ssh
      hostname processing for authorized_keys, not known_hosts;
    * ssh(1): Fix authentication using lone certificate keys in an
      agent without corresponding private keys on the filesystem.
    * sshd(8): Send ClientAliveInterval pings when a time-based
      RekeyLimit is set; previously keepalive packets were not
      being sent. bz#2252
    - --- Portability
    * ssh(1), sshd(8): Fix compilation by automatically disabling
      ciphers not supported by OpenSSL. bz#2466
    * misc: Fix compilation failures on some versions of AIX's
      compiler related to the definition of the VA_COPY macro.
    * sshd(8): Whitelist more architectures to enable the
      seccomp-bpf sandbox. bz#2590
    * ssh-agent(1), sftp-server(8): Disable process tracing on
      Solaris using setpflags(__PROC_PROTECT, ...). bz#2584
    * sshd(8): On Solaris, don't call Solaris setproject() with
      UsePAM=yes it's PAM's responsibility. bz#2425
  - OpenSSH 7.4
    - --- Potentially-incompatible changes
    * ssh(1): Remove 3des-cbc from the client's default proposal.
      64-bit block ciphers are not safe in 2016 and we don't want
      to wait until attacks like SWEET32 are extended to SSH. As
      3des-cbc was the only mandatory cipher in the SSH RFCs, this
      may cause problems connecting to older devices using the
      default configuration, but it's highly likely that such
      devices already need explicit configuration for key exchange
      and hostkey algorithms already anyway.
    * sshd(8): Remove support for pre-authentication compression.
      Doing compression early in the protocol probably seemed
      reasonable in the 1990s, but today it's clearly a bad idea in
      terms of both cryptography (cf. multiple compression oracle
      attacks in TLS) and attack surface. Pre-auth compression
      support has been disabled by default for >10 years. Support
      remains in the client.
    * ssh-agent will refuse to load PKCS#11 modules outside a
      whitelist of trusted paths by default. The path whitelist may
      be specified at run-time.
    * sshd(8): When a forced-command appears in both a certificate
      and an authorized keys/principals command= restriction, sshd
      will now refuse to accept the certificate unless they are
      identical.  The previous (documented) behaviour of having the
      certificate forced-command override the other could be a bit
      confusing and error-prone.
    * sshd(8): Remove the UseLogin configuration directive and
      support for having /bin/login manage login sessions.
    - --- Security
    * ssh-agent(1): Will now refuse to load PKCS#11 modules from
      paths outside a trusted whitelist (run-time configurable).
      Requests to load modules could be passed via agent forwarding
      and an attacker could attempt to load a hostile PKCS#11
      module across the forwarded agent channel: PKCS#11 modules
      are shared libraries, so this would result in code execution
      on the system running the ssh-agent if the attacker has
      control of the forwarded agent-socket (on the host running
      the sshd server) and the ability to write to the filesystem
      of the host running ssh-agent (usually the host running the
      ssh client). Reported by Jann Horn of Project Zero.
    * sshd(8): When privilege separation is disabled, forwarded
      Unix- domain sockets would be created by sshd(8) with the
      privileges of 'root' instead of the authenticated user. This
      release refuses Unix-domain socket forwarding when privilege
      separation is disabled (Privilege separation has been enabled
      by default for 14 years).  Reported by Jann Horn of Project
    * sshd(8): Avoid theoretical leak of host private key material
      to privilege-separated child processes via realloc() when
      reading keys. No such leak was observed in practice for
      normal-sized keys, nor does a leak to the child processes
      directly expose key material to unprivileged users. Reported
      by Jann Horn of Project Zero.
    * sshd(8): The shared memory manager used by pre-authentication
      compression support had a bounds checks that could be elided
      by some optimising compilers. Additionally, this memory
      manager was incorrectly accessible when pre-authentication
      compression was disabled. This could potentially allow
      attacks against the privileged monitor process from the
      sandboxed privilege-separation process (a compromise of the
      latter would be required first).  This release removes
      support for pre-authentication compression from sshd(8).
      Reported by Guido Vranken using the Stack unstable
      optimisation identification tool
    * sshd(8): Fix denial-of-service condition where an attacker
      who sends multiple KEXINIT messages may consume up to 128MB
      per connection. Reported by Shi Lei of Gear Team, Qihoo 360.
    * sshd(8): Validate address ranges for AllowUser and DenyUsers
      directives at configuration load time and refuse to accept
      invalid ones. It was previously possible to specify invalid
      CIDR address ranges (e.g. user@ and these would
      always match, possibly resulting in granting access where it
      was not intended.  Reported by Laurence Parry.
    - --- New Features
    * ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by
      the version in PuTTY by Simon Tatham. This allows a
      multiplexing client to communicate with the master process
      using a subset of the SSH packet and channels protocol over a
      Unix-domain socket, with the main process acting as a proxy
      that translates channel IDs, etc.  This allows multiplexing
      mode to run on systems that lack file- descriptor passing
      (used by current multiplexing code) and potentially, in
      conjunction with Unix-domain socket forwarding, with the
      client and multiplexing master process on different machines.
      Multiplexing proxy mode may be invoked using "ssh -O proxy
    * sshd(8): Add a sshd_config DisableForwarding option that
      disables X11, agent, TCP, tunnel and Unix domain socket
      forwarding, as well as anything else we might implement in
      the future. Like the 'restrict' authorized_keys flag, this is
      intended to be a simple and future-proof way of restricting
      an account.
    * sshd(8), ssh(1): Support the "curve25519-sha256" key exchange
      method. This is identical to the currently-supported method
      named "".
    * sshd(8): Improve handling of SIGHUP by checking to see if
      sshd is already daemonised at startup and skipping the call
      to daemon(3) if it is. This ensures that a SIGHUP restart of
      sshd(8) will retain the same process-ID as the initial
      execution. sshd(8) will also now unlink the PidFile prior to
      SIGHUP restart and re-create it after a successful restart,
      rather than leaving a stale file in the case of a
      configuration error. bz#2641
    * sshd(8): Allow ClientAliveInterval and ClientAliveCountMax
      directives to appear in sshd_config Match blocks.
    * sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to
      match those supported by AuthorizedKeysCommand (key, key
      type, fingerprint, etc.) and a few more to provide access to
      the contents of the certificate being offered.
    * Added regression tests for string matching, address matching
      and string sanitisation functions.
    * Improved the key exchange fuzzer harness.
    - --- Bugfixes
    * ssh(1): Allow IdentityFile to successfully load and use
      certificates that have no corresponding bare public key.
      bz#2617 certificate (and no
    * ssh(1): Fix public key authentication when multiple
      authentication is in use and publickey is not just the first
      method attempted. bz#2642
    * regress: Allow the PuTTY interop tests to run unattended.
    * ssh-agent(1), ssh(1): improve reporting when attempting to
      load keys from PKCS#11 tokens with fewer useless log messages
      and more detail in debug messages. bz#2610
    * ssh(1): When tearing down ControlMaster connections, don't
      pollute stderr when LogLevel=quiet.
    * sftp(1): On ^Z wait for underlying ssh(1) to suspend before
      suspending sftp(1) to ensure that ssh(1) restores the
      terminal mode correctly if suspended during a password
    * ssh(1): Avoid busy-wait when ssh(1) is suspended during a
      password prompt.
    * ssh(1), sshd(8): Correctly report errors during sending of
      ext- info messages.
    * sshd(8): fix NULL-deref crash if sshd(8) received an out-of-
      sequence NEWKEYS message.
    * sshd(8): Correct list of supported signature algorithms sent
      in the server-sig-algs extension. bz#2547
    * sshd(8): Fix sending ext_info message if privsep is disabled.
    * sshd(8): more strictly enforce the expected ordering of
      privilege separation monitor calls used for authentication
      and allow them only when their respective authentication
      methods are enabled in the configuration
    * sshd(8): Fix uninitialised optlen in getsockopt() call;
      harmless on Unix/BSD but potentially crashy on Cygwin.
    * Fix false positive reports caused by explicit_bzero(3) not
      being recognised as a memory initialiser when compiled with
    - fsanitize-memory.
    * sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet
      for configuration examples.
    - --- Portability
    * On environments configured with Turkish locales, fall back to
      the C/POSIX locale to avoid errors in configuration parsing
      caused by that locale's unique handling of the letters 'i'
      and 'I'. bz#2643
    * sftp-server(8), ssh-agent(1): Deny ptrace on OS X using
      ptrace(PT_DENY_ATTACH, ..)
    * ssh(1), sshd(8): Unbreak AES-CTR ciphers on old (~0.9.8)
    * Fix compilation for libcrypto compiled without RIPEMD160
    * contrib: Add a gnome-ssh-askpass3 with GTK+3 support. bz#2640
    * sshd(8): Improve PRNG reseeding across privilege separation
      and force libcrypto to obtain a high-quality seed before
      chroot or sandboxing.
    * All: Explicitly test for broken strnvis. NetBSD added an
      strnvis and unfortunately made it incompatible with the
      existing one in OpenBSD and Linux's libbsd (the former having
      existed for over ten years). Try to detect this mess, and
      assume the only safe option if we're cross compiling.
  - OpenSSH 7.5
    - --- Potentially-incompatible changes
    * This release deprecates the sshd_config
      UsePrivilegeSeparation option, thereby making privilege
      separation mandatory. Privilege separation has been on by
      default for almost 15 years and sandboxing has been on by
      default for almost the last five.
    * The format of several log messages emitted by the packet code
      has changed to include additional information about the user
      and their authentication state. Software that monitors
      ssh/sshd logs may need to account for these changes. For
    Connection closed by user x port 1234 [preauth]
    Connection closed by authenticating user x port 1234
    [preauth] Connection closed by invalid user x port
    1234 [preauth]
    Affected messages include connection closure, timeout, remote
    disconnection, negotiation failure and some other fatal
    messages generated by the packet code.
    * [Portable OpenSSH only] This version removes support for
      building against OpenSSL versions prior to 1.0.1. OpenSSL
      stopped supporting versions prior to 1.0.1 over 12 months ago
      (i.e. they no longer receive fixes for security bugs).
    - --- Security
    * ssh(1), sshd(8): Fix weakness in CBC padding oracle
      countermeasures that allowed a variant of the attack fixed in
      OpenSSH 7.3 to proceed.  Note that the OpenSSH client
      disables CBC ciphers by default, sshd offers them as
      lowest-preference options and will remove them by default
      entriely in the next release. Reported by Jean Paul
      Degabriele, Kenny Paterson, Martin Albrecht and Torben Hansen
      of Royal Holloway, University of London.
    * sftp-client(1): [portable OpenSSH only] On Cygwin, a client
      making a recursive file transfer could be maniuplated by a
      hostile server to perform a path-traversal attack. creating
      or modifying files outside of the intended target directory.
      Reported by Jann Horn of Google Project Zero.
    - --- New Features
    * ssh(1), sshd(8): Support "=-" syntax to easily remove methods
      from algorithm lists, e.g. Ciphers=-*cbc. bz#2671
    - --- Bugfixes
    * sshd(1): Fix NULL dereference crash when key exchange start
      messages are sent out of sequence.
    * ssh(1), sshd(8): Allow form-feed characters to appear in
      configuration files.
    * sshd(8): Fix regression in OpenSSH 7.4 support for the
      server-sig-algs extension, where SHA2 RSA signature methods
      were not being correctly advertised. bz#2680
    * ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs
      in known_hosts processing. bz#2591 bz#2685
    * ssh(1): Allow ssh to use certificates accompanied by a
      private key file but no corresponding plain *.pub public key.
    * ssh(1): When updating hostkeys using the UpdateHostKeys
      option, accept RSA keys if HostkeyAlgorithms contains any RSA
      keytype.  Previously, ssh could ignore RSA keys when only the
      ssh-rsa-sha2-* methods were enabled in HostkeyAlgorithms and
      not the old ssh-rsa method. bz#2650
    * ssh(1): Detect and report excessively long configuration file
      lines. bz#2651
    * Merge a number of fixes found by Coverity and reported via
      Redhat and FreeBSD. Includes fixes for some memory and file
      descriptor leaks in error paths. bz#2687
    * ssh-keyscan(1): Correctly hash hosts with a port number.
    * ssh(1), sshd(8): When logging long messages to stderr, don't
      truncate "\r\n" if the length of the message exceeds the
      buffer. bz#2688
    * ssh(1): Fully quote [host]:port in generated ProxyJump/-J
      command- line; avoid confusion over IPv6 addresses and shells
      that treat square bracket characters specially.
    * ssh-keygen(1): Fix corruption of known_hosts when running
      "ssh-keygen -H" on a known_hosts containing already-hashed
    * Fix various fallout and sharp edges caused by removing SSH
      protocol 1 support from the server, including the server
      banner string being incorrectly terminated with only \n
      (instead of \r\n), confusing error messages from ssh-keyscan
      bz#2583 and a segfault in sshd if protocol v.1 was enabled
      for the client and sshd_config contained references to legacy
      keys bz#2686.
    * ssh(1), sshd(8): Free fd_set on connection timeout. bz#2683
    * sshd(8): Fix Unix domain socket forwarding for root
      (regression in OpenSSH 7.4).
    * sftp(1): Fix division by zero crash in "df" output when
      server returns zero total filesystem blocks/inodes.
    * ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL
      errors encountered during key loading to more meaningful
      error codes.  bz#2522 bz#2523
    * ssh-keygen(1): Sanitise escape sequences in key comments sent
      to printf but preserve valid UTF-8 when the locale supports
      it; bz#2520
    * ssh(1), sshd(8): Return reason for port forwarding failures
      where feasible rather than always "administratively
      prohibited". bz#2674
    * sshd(8): Fix deadlock when AuthorizedKeysCommand or
      AuthorizedPrincipalsCommand produces a lot of output and a
      key is matched early. bz#2655
    * Regression tests: several reliability fixes. bz#2654 bz#2658
    * ssh(1): Fix typo in ~C error message for bad port forward
      cancellation. bz#2672
    * ssh(1): Show a useful error message when included config
      files can't be opened; bz#2653
    * sshd(8): Make sshd set GSSAPIStrictAcceptorCheck=yes as the
      manual page (previously incorrectly) advertised. bz#2637
    * sshd_config(5): Repair accidentally-deleted mention of %k
      token in AuthorizedKeysCommand; bz#2656
    * sshd(8): Remove vestiges of previously removed LOGIN_PROGRAM;
    * ssh-agent(1): Relax PKCS#11 whitelist to include libexec and
      common 32-bit compatibility library directories.
    * sftp-client(1): Fix non-exploitable integer overflow in
      SSH2_FXP_NAME response handling.
    * ssh-agent(1): Fix regression in 7.4 of deleting
      PKCS#11-hosted keys. It was not possible to delete them
      except by specifying their full physical path. bz#2682
    - --- Portability
    * sshd(8): Avoid sandbox errors for Linux S390 systems using an
      ICA crypto coprocessor.
    * sshd(8): Fix non-exploitable weakness in seccomp-bpf sandbox
      arg inspection.
    * ssh(1): Fix X11 forwarding on OSX where X11 was being started
      by launchd. bz#2341
    * ssh-keygen(1), ssh(1), sftp(1): Fix output truncation for
      various that contain non-printable characters where the
      codeset in use is ASCII.
    * build: Fix builds that attempt to link a kerberised libldns.
    * build: Fix compilation problems caused by unconditionally
      defining _XOPEN_SOURCE in wide character detection.
    * sshd(8): Fix sandbox violations for clock_gettime VSDO
      syscall fallback on some Linux/X32 kernels. bz#2142
  - OpenSSH 7.6
    - --- Potentially-incompatible changes
    This release includes a number of changes that may affect
    existing configurations:
    * ssh(1): delete SSH protocol version 1 support, associated
      configuration options and documentation.
    * ssh(1)/sshd(8): remove support for the hmac-ripemd160 MAC.
    * ssh(1)/sshd(8): remove support for the arcfour, blowfish and
      CAST ciphers.
    * Refuse RSA keys <1024 bits in length and improve reporting
      for keys that do not meet this requirement.
    * ssh(1): do not offer CBC ciphers by default.
    - --- Security
    * sftp-server(8): in read-only mode, sftp-server was
      incorrectly permitting creation of zero-length files.
      Reported by Michal Zalewski.
    - --- New Features
    * ssh(1): add RemoteCommand option to specify a command in the
      ssh config file instead of giving it on the client's command
      line. This allows the configuration file to specify the
      command that will be executed on the remote host.
    * sshd(8): add ExposeAuthInfo option that enables writing
      details of the authentication methods used (including public
      keys where applicable) to a file that is exposed via a
      $SSH_USER_AUTH environment variable in the subsequent
    * ssh(1): add support for reverse dynamic forwarding. In this
      mode, ssh will act as a SOCKS4/5 proxy and forward
      connections to destinations requested by the remote SOCKS
      client. This mode is requested using extended syntax for the
    - R and RemoteForward options and, because it is implemented
      solely at the client, does not require the server be updated
      to be supported.
    * sshd(8): allow LogLevel directive in sshd_config Match
      blocks; bz#2717
    * ssh-keygen(1): allow inclusion of arbitrary string or flag
      certificate extensions and critical options.
    * ssh-keygen(1): allow ssh-keygen to use a key held in
      ssh-agent as a CA when signing certificates. bz#2377
    * ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an
      explicit ToS/DSCP value and just use the operating system
    * ssh-add(1): added -q option to make ssh-add quiet on success.
    * ssh(1): expand the StrictHostKeyChecking option with two new
      settings. The first "accept-new" will automatically accept
      hitherto-unseen keys but will refuse connections for changed
      or invalid hostkeys. This is a safer subset of the current
      behaviour of StrictHostKeyChecking=no. The second setting
      "off", is a synonym for the current behaviour of
      StrictHostKeyChecking=no: accept new host keys, and continue
      connection for hosts with incorrect hostkeys. A future
      release will change the meaning of StrictHostKeyChecking=no
      to the behaviour of "accept-new". bz#2400
    * ssh(1): add SyslogFacility option to ssh(1) matching the
      equivalent option in sshd(8). bz#2705
    - --- Bugfixes
    * ssh(1): use HostKeyAlias if specified instead of hostname for
      matching host certificate principal names; bz#2728
    * sftp(1): implement sorting for globbed ls; bz#2649
    * ssh(1): add a user@host prefix to client's "Permission
      denied" messages, useful in particular when using "stacked"
      connections (e.g. ssh -J) where it's not clear which host is
      denying. bz#2720
    * ssh(1): accept unknown EXT_INFO extension values that contain
      \0 characters. These are legal, but would previously cause
      fatal connection errors if received.
    * ssh(1)/sshd(8): repair compression statistics printed at
      connection exit
    * sftp(1): print '?' instead of incorrect link count (that the
      protocol doesn't provide) for remote listings. bz#2710
    * ssh(1): return failure rather than fatal() for more cases
      during session multiplexing negotiations. Causes the session
      to fall back to a non-mux connection if they occur. bz#2707
    * ssh(1): mention that the server may send debug messages to
      explain public key authentication problems under some
      circumstances; bz#2709
    * Translate OpenSSL error codes to better report incorrect
      passphrase errors when loading private keys; bz#2699
    * sshd(8): adjust compatibility patterns for WinSCP to
      correctly identify versions that implement only the legacy DH
      group exchange scheme. bz#2748
    * ssh(1): print the "Killed by signal 1" message only at
      LogLevel verbose so that it is not shown at the default
      level; prevents it from appearing during ssh -J and
      equivalent ProxyCommand configs.  bz#1906, bz#2744
    * ssh-keygen(1): when generating all hostkeys (ssh-keygen -A),
      clobber existing keys if they exist but are zero length.
      zero-length keys could previously be made if ssh-keygen
      failed or was interrupted part way through generating them.
    * ssh(1): fix pledge(2) violation in the escape sequence "~&"
      used to place the current session in the background.
    * ssh-keyscan(1): avoid double-close() on file descriptors;
    * sshd(8): avoid reliance on shared use of pointers shared
      between monitor and child sshd processes. bz#2704
    * sshd_config(8): document available AuthenticationMethods;
    * ssh(1): avoid truncation in some login prompts; bz#2768
    * sshd(8): Fix various compilations failures, inc bz#2767
    * ssh(1): make "--" before the hostname terminate argument
      processing after the hostname too.
    * ssh-keygen(1): switch from aes256-cbc to aes256-ctr for
      encrypting new-style private keys. Fixes problems related to
      private key handling for no-OpenSSL builds. bz#2754
    * ssh(1): warn and do not attempt to use keys when the public
      and private halves do not match. bz#2737
    * sftp(1): don't print verbose error message when ssh
      disconnects from under sftp. bz#2750
    * sshd(8): fix keepalive scheduling problem: activity on a
      forwarded port from preventing the keepalive from being sent;
    * sshd(8): when started without root privileges, don't require
      the privilege separation user or path to exist. Makes running
      the regression tests easier without touching the filesystem.
    * Make regression tests more robust against
      timeouts.  bz#2658
    * ssh(1)/sshd(8): correctness fix for channels implementation:
      accept channel IDs greater than 0x7FFFFFFF.
    - --- Portability
    * sshd(9): drop two more privileges in the Solaris sandbox:
    * sshd(8): expose list of completed authentication methods to
      PAM via the SSH_AUTH_INFO_0 PAM environment variable. bz#2408
    * ssh(1)/sshd(8): fix several problems in the tun/tap
      forwarding code, mostly to do with host/network byte order
      confusion. bz#2735
    * Add --with-cflags-after and --with-ldflags-after configure
      flags to allow setting CFLAGS/LDFLAGS after configure has
      completed. These are useful for setting sanitiser/fuzzing
      options that may interfere with configure's operation.
    * sshd(8): avoid Linux seccomp violations on ppc64le over the
      socketcall syscall.
    * Fix use of ldns when using ldns-config; bz#2697
    * configure: set cache variables when cross-compiling. The
      cross- compiling fallback message was saying it assumed the
      test passed, but it wasn't actually set the cache variables
      and this would cause later tests to fail.
    * Add clang libFuzzer harnesses for public key parsing and
      signature verification.
  - packaging:
    * moving patches into a separate archive
    * first round of rebased patches:
    * not rebased (obsoleted) patches (so far):
    * obviously removing all standalone patch files:


No Filelist in the Package !
