Log Message:
Changes since OpenSSH 6.1
=========================

This release introduces a number of new features:

Features:

 * ssh(1)/sshd(8): Added support for AES-GCM authenticated encryption in
   SSH protocol 2. The new cipher is available as 
aes128-gcm%openssh.com@localhost
   and aes256-gcm%openssh.com@localhost. It uses an identical packet format to 
the
   AES-GCM mode specified in RFC 5647, but uses simpler and different
   selection rules during key exchange.

 * ssh(1)/sshd(8): Added support for encrypt-then-mac (EtM) MAC modes
   for SSH protocol 2. These modes alter the packet format and compute
   the MAC over the packet length and encrypted packet rather than over
   the plaintext data. These modes are considered more secure and are
   used by default when available.

 * ssh(1)/sshd(8): Added support for the UMAC-128 MAC as
   "umac-128%openssh.com@localhost" and "umac-128-etm%openssh.com@localhost". 
The latter
   being an encrypt-then-mac mode.

 * sshd(8): Added support for multiple required authentication in SSH
   protocol 2 via an AuthenticationMethods option. This option lists
   one or more comma-separated lists of authentication method names.
   Successful completion of all the methods in any list is required for
   authentication to complete. This allows, for example, requiring a
   user having to authenticate via public key or GSSAPI before they
   are offered password authentication.

 * sshd(8)/ssh-keygen(1): Added support for Key Revocation Lists
   (KRLs), a compact binary format to represent lists of revoked keys
   and certificates that take as little as one bit per certificate when
   revoking by serial number. KRLs may be generated using ssh-keygen(1)
   and are loaded into sshd(8) via the existing RevokedKeys sshd_config
   option.

 * ssh(1): IdentitiesOnly now applies to keys obtained from a
   PKCS11Provider. This allows control of which keys are offered from
   tokens using IdentityFile.

 * sshd(8): sshd_config(5)'s AllowTcpForwarding now accepts "local"
   and "remote" in addition to its previous "yes"/"no" keywords to allow
   the server to specify whether just local or remote TCP forwarding is
   enabled.

 * sshd(8): Added a sshd_config(5) option AuthorizedKeysCommand to
   support fetching authorized_keys from a command in addition to (or
   instead of) from the filesystem. The command is run under an account
   specified by an AuthorizedKeysCommandUser sshd_config(5) option.

 * sftp-server(8): Now supports a -d option to allow the starting
   directory to be something other than the user's home directory.

 * ssh-keygen(1): Now allows fingerprinting of keys hosted in PKCS#11
   tokens using "ssh-keygen -lD pkcs11_provider".

 * ssh(1): When SSH protocol 2 only is selected (the default), ssh(1)
   now immediately sends its SSH protocol banner to the server without
   waiting to receive the server's banner, saving time when connecting.

 * ssh(1): Added ~v and ~V escape sequences to raise and lower the
   logging level respectively.

 * ssh(1): Made the escape command help (~?) context sensitive so that
   only commands that will work in the current session are shown.

 * ssh-keygen(1): When deleting host lines from known_hosts using
   "ssh-keygen -R host", ssh-keygen(1) now prints details of which lines
   were removed.

Bugfixes:

 * ssh(1): Force a clean shutdown of ControlMaster client sessions when
   the ~. escape sequence is used. This means that ~. should now work in
   mux clients even if the server is no longer responding.

 * ssh(1): Correctly detect errors during local TCP forward setup in
   multiplexed clients. bz#2055

 * ssh-add(1): Made deleting explicit keys "ssh-add -d" symmetric with
   adding keys with respect to certificates. It now tries to delete the
   corresponding certificate and respects the -k option to allow deleting
   of the key only.

 * sftp(1): Fix a number of parsing and command-editing bugs, including
   bz#1956

 * ssh(1): When muxmaster is run with -N, ensured that it shuts down
   gracefully when a client sends it "-O stop" rather than hanging around.
   bz#1985

 * ssh-keygen(1): When screening moduli candidates, append to the file
   rather than overwriting to allow resumption. bz#1957

 * ssh(1): Record "Received disconnect" messages at ERROR rather than
   INFO priority. bz#2057.

 * ssh(1): Loudly warn if explicitly-provided private key is unreadable.
   bz#1981

Portable OpenSSH:

 * sshd(8): The Linux seccomp-filter sandbox is now supported on ARM
   platforms where the kernel supports it.

 * sshd(8): The seccomp-filter sandbox will not be enabled if the system
   headers support it at compile time, regardless of whether it can be
   enabled then. If the run-time system does not support seccomp-filter,
   sshd will fall back to the rlimit pseudo-sandbox.

 * ssh(1): Don't link in the Kerberos libraries. They aren't necessary
   on the client, just on sshd(8). bz#2072

 * Fix GSSAPI linking on Solaris, which uses a differently-named GSSAPI
   library. bz#2073

 * Fix compilation on systems with openssl-1.0.0-fips.

 * Fix a number of errors in the RPM spec files.

Changes since OpenSSH 6.0
=========================

This is primarily a bugfix release.

Features:

 * sshd(8): This release turns on pre-auth sandboxing sshd by default for
   new installs, by setting UsePrivilegeSeparation=sandbox in sshd_config.
 * ssh-keygen(1): Add options to specify starting line number and number of
   lines to process when screening moduli candidates, allowing processing
   of different parts of a candidate moduli file in parallel
 * sshd(8): The Match directive now supports matching on the local (listen)
   address and port upon which the incoming connection was received via
   LocalAddress and LocalPort clauses.
 * sshd(8): Extend sshd_config Match directive to allow setting AcceptEnv
   and {Allow,Deny}{Users,Groups}
 * Add support for RFC6594 SSHFP DNS records for ECDSA key types. bz#1978
 * ssh-keygen(1): Allow conversion of RSA1 keys to public PEM and PKCS8
 * sshd(8): Allow the sshd_config PermitOpen directive to accept "none" as
   an argument to refuse all port-forwarding requests.
 * sshd(8): Support "none" as an argument for AuthorizedPrincipalsFile
 * ssh-keyscan(1): Look for ECDSA keys by default. bz#1971
 * sshd(8): Add "VersionAddendum" to sshd_config to allow server operators
   to append some arbitrary text to the server SSH protocol banner.

Bugfixes:

 * ssh(1)/sshd(8): Don't spin in accept() in situations of file
   descriptor exhaustion. Instead back off for a while.
 * ssh(1)/sshd(8): Remove hmac-sha2-256-96 and hmac-sha2-512-96 MACs as
   they were removed from the specification. bz#2023,
 * sshd(8): Handle long comments in config files better. bz#2025
 * ssh(1): Delay setting tty_flag so RequestTTY options are correctly
   picked up. bz#1995
 * sshd(8): Fix handling of /etc/nologin incorrectly being applied to root
   on platforms that use login_cap.

Portable OpenSSH:

 * sshd(8): Allow sshd pre-auth sandboxing to fall-back to the rlimit
   sandbox from the Linux SECCOMP filter sandbox when the latter is
   not available in the kernel.
 * ssh(1): Fix NULL dereference when built with LDNS and using DNSSEC to
   retrieve a CNAME SSHFP record.
 * Fix cross-compilation problems related to pkg-config. bz#1996

Changes since OpenSSH 5.9
=========================

This is primarily a bugfix release.

Features:

 * ssh-keygen(1): Add optional checkpoints for moduli screening
 * ssh-add(1): new -k option to load plain keys (skipping certificates)
 * sshd(8): Add wildcard support to PermitOpen, allowing things like
   "PermitOpen localhost:*".  bz #1857
 * ssh(1): support for cancelling local and remote port forwards via the
   multiplex socket. Use ssh -O cancel -L xx:xx:xx -R yy:yy:yy user@host"
   to request the cancellation of the specified forwardings
 * support cancellation of local/dynamic forwardings from ~C commandline

Bugfixes:

 * ssh(1): ensure that $DISPLAY contains only valid characters before
   using it to extract xauth data so that it can't be used to play local
   shell metacharacter games.
 * ssh(1): unbreak remote portforwarding with dynamic allocated listen ports
 * scp(1): uppress adding '--' to remote commandlines when the first
   argument does not start with '-'. saves breakage on some
   difficult-to-upgrade embedded/router platforms
 * ssh(1)/sshd(8): fix typo in IPQoS parsing: there is no "AF14" class,
   but there is an "AF21" class
 * ssh(1)/sshd(8): do not permit SSH2_MSG_SERVICE_REQUEST/ACCEPT during
   rekeying
 * ssh(1): skip attempting to create ~/.ssh when -F is passed
 * sshd(8): unbreak stdio forwarding when ControlPersist is in use; bz#1943
 * sshd(1): send tty break to pty master instead of (probably already
   closed) slave side; bz#1859
 * sftp(1): silence error spam for "ls */foo" in directory with files;
   bz#1683
 * Fixed a number of memory and file descriptor leaks

Portable OpenSSH:

 * Add a new privilege separation sandbox implementation for Linux's
   new seccomp sandbox, automatically enabled on platforms that support
   it. (Note: privilege separation sandboxing is still experimental)
 * Fix compilation problems on FreeBSD, where libutil contained openpty()
   but not login().
 * ssh-keygen(1): don't fail in -A on platforms that don't support ECC
 * Add optional support for LDNS, a BSD licensed DNS resolver library
   which supports DNSSEC
 * Relax OpenSSL version check to allow running OpenSSH binaries on
   systems with OpenSSL libraries with a newer "fix" or "patch" level
   than the binaries were originally compiled on (previous check only
   allowed movement within "patch" releases). bz#1991
 * Fix builds using contributed Redhat spec file. bz#1992

Changes since OpenSSH 5.8
=========================

Features:

 * Introduce sandboxing of the pre-auth privsep child using an optional
   sshd_config(5) "UsePrivilegeSeparation=sandbox" mode that enables
   mandatory restrictions on the syscalls the privsep child can perform.
   This intention is to prevent a compromised privsep child from being
   used to attack other hosts (by opening sockets and proxying) or
   probing local kernel attack surface.

   Three concrete sandbox implementation are provided (selected at
   configure time): systrace, seatbelt and rlimit.

   The systrace sandbox uses systrace(4) in unsupervised "fast-path"
   mode, where a list of permitted syscalls is supplied. Any syscall not
   on the list results in SIGKILL being sent to the privsep child. Note
   that this requires a kernel with the new SYSTR_POLICY_KILL option
   (only OpenBSD has this mode at present).

   The seatbelt sandbox uses OS X/Darwin sandbox(7) facilities with a
   strict (kSBXProfilePureComputation) policy that disables access to
   filesystem and network resources.

   The rlimit sandbox is a fallback choice for platforms that don't
   support a better one; it uses setrlimit() to reset the hard-limit
   of file descriptors and processes to zero, which should prevent
   the privsep child from forking or opening new network connections.

   Sandboxing of the privilege separated child process is currently
   experimental but should become the default in a future release.
   Native sandboxes for other platforms are welcome (e.g. Capsicum,
   Linux pid/net namespaces, etc.)

 * Add new SHA256-based HMAC transport integrity modes from
   http://www.ietf.org/id/draft-dbider-sha2-mac-for-ssh-02.txt
   These modes are hmac-sha2-256, hmac-sha2-256-96, hmac-sha2-512,
   and hmac-sha2-512-96, and are available by default in ssh(1) and
   sshd(8)

 * The pre-authentication sshd(8) privilege separation slave process
   now logs via a socket shared with the master process, avoiding the
   need to maintain /dev/log inside the chroot.

 * ssh(1) now warns when a server refuses X11 forwarding

 * sshd_config(5)'s AuthorizedKeysFile now accepts multiple paths,
   separated by whitespace. The undocumented AuthorizedKeysFile2
   option is deprecated (though the default for AuthorizedKeysFile
   includes .ssh/authorized_keys2)

 * sshd_config(5): similarly deprecate UserKnownHostsFile2 and
   GlobalKnownHostsFile2 by making UserKnownHostsFile and
   GlobalKnownHostsFile accept multiple options and default to
   include known_hosts2

 * Retain key comments when loading v.2 keys. These will be visible
   in "ssh-add -l" and other places. bz#439

 * ssh(1) and sshd(8): set IPv6 traffic class from IPQoS (as well as
   IPv4 ToS/DSCP). bz#1855

 * ssh_config(5)'s ControlPath option now expands %L to the host
   portion of the destination host name.

 * ssh_config(5) "Host" options now support negated Host matching, e.g.

     Host *.example.org !c.example.org
        User mekmitasdigoat

   Will match "a.example.org", "b.example.org", but not "c.example.org"

 * ssh_config(5): a new RequestTTY option provides control over when a
   TTY is requested for a connection, similar to the existing -t/-tt/-T
   ssh(1) commandline options.

 * sshd(8): allow GSSAPI authentication to detect when a server-side
   failure causes authentication failure and don't count such failures
   against MaxAuthTries; bz#1244

 * ssh-keygen(1): Add -A option. For each of the key types (rsa1, rsa,
   dsa and ecdsa) for which host keys do not exist, generate the host
   keys with the default key file path, an empty passphrase, default
   bits for the key type, and default comment. This is useful for
   system initialisation scripts.

 * ssh(1): Allow graceful shutdown of multiplexing: request that a mux
   server removes its listener socket and refuse future multiplexing
   requests but don't kill existing connections. This may be requested
   using "ssh -O stop ..."

 * ssh-add(1) now accepts keys piped from standard input. E.g.
   "ssh-add - < /path/to/key"

 * ssh-keysign(8) now signs hostbased authentication
   challenges correctly using ECDSA keys; bz#1858

 * sftp(1): document that sftp accepts square brackets to delimit
   addresses (useful for IPv6); bz#1847a

 * ssh(1): when using session multiplexing, the master process will
   change its process title to reflect the control path in use and
   when a ControlPersist-ed master is waiting to close; bz#1883 and
   bz#1911

 * Other minor bugs fixed: 1849 1861 1862 1869 1875 1878 1879 1892
   1900 1905 1913

Portable OpenSSH Bugfixes:

 * Fix a compilation error in the SELinux support code. bz#1851

 * This release removes support for ssh-rand-helper. OpenSSH now
   obtains its random numbers directly from OpenSSL or from
   a PRNGd/EGD instance specified at configure time.

 * sshd(8) now resets the SELinux process execution context before
   executing passwd for password changes; bz#1891

 * Since gcc >= 4.x ignores all -Wno-options options, test only the
   corresponding -W-option when trying to determine whether it is
   accepted; bz#1901

 * Add ECDSA key generation to the Cygwin ssh-{host,user}-config
   scripts.

 * Updated .spec and init files for Linux; bz#1920

 * Improved SELinux error messages in context change failures and
   suppress error messages when attempting to change from the
   "unconfined_t" type; bz#1924 bz#1919

 * Fix build errors on platforms without dlopen(); bz#1929
