 openssh (1:5.1p1-1ubuntu1) intrepid; urgency=low
   * Resynchronise with Debian. Remaining changes:
     - Add support for registering ConsoleKit sessions on login.
     - Drop openssh-blacklist and openssh-blacklist-extra to Suggests; they
       take up a lot of CD space, and I suspect that rolling them out in
       security updates has covered most affected systems now.
 openssh (1:5.1p1-1) unstable; urgency=low
   * New upstream release (closes: #474301). Important changes not previously
     backported to 4.7p1:
     - 4.9/4.9p1 (
       + Added chroot(2) support for sshd(8), controlled by a new option
         "ChrootDirectory" (closes: #139047, LP: #24777).
       + Linked sftp-server(8) into sshd(8). The internal sftp server is used
         when the command "internal-sftp" is specified in a Subsystem or
         ForceCommand declaration. When used with ChrootDirectory, the
         internal sftp server requires no special configuration of files
         inside the chroot environment.
       + Added a protocol extension method "posix-rename at" for
         sftp-server(8) to perform POSIX atomic rename() operations; sftp(1)
         prefers this if available (closes: #308561).
       + Removed the fixed limit of 100 file handles in sftp-server(8).
       + ssh(8) will now skip generation of SSH protocol 1 ephemeral server
         keys when in inetd mode and protocol 2 connections are negotiated.
         This speeds up protocol 2 connections to inetd-mode servers that
         also allow Protocol 1.
       + Accept the PermitRootLogin directive in a sshd_config(5) Match
         block. Allows for, e.g. permitting root only from the local network.
       + Reworked sftp(1) argument splitting and escaping to be more
         internally consistent (i.e. between sftp commands) and more
         consistent with sh(1). Please note that this will change the
         interpretation of some quoted strings, especially those with
         embedded backslash escape sequences.
       + Support "Banner=none" in sshd_config(5) to disable sending of a
         pre-login banner (e.g. in a Match block).
       + ssh(1) ProxyCommands are now executed with $SHELL rather than
       + ssh(1)'s ConnectTimeout option is now applied to both the TCP
         connection and the SSH banner exchange (previously it just covered
         the TCP connection). This allows callers of ssh(1) to better detect
         and deal with stuck servers that accept a TCP connection but don't
         progress the protocol, and also makes ConnectTimeout useful for
         connections via a ProxyCommand.
       + scp(1) incorrectly reported "stalled" on slow copies (closes:
       + scp(1) date underflow for timestamps before epoch.
       + ssh(1) used the obsolete SIG DNS RRtype for host keys in DNS,
         instead of the current standard RRSIG.
       + Correctly drain ACKs when a sftp(1) upload write fails midway,
         avoids a fatal() exit from what should be a recoverable condition.
       + Fixed ssh-keygen(1) selective host key hashing (i.e. "ssh-keygen -HF
         hostname") to not include any IP address in the data to be hashed.
       + Make ssh(1) skip listening on the IPv6 wildcard address when a
         binding address of is used against an old SSH server that
         does not support the RFC4254 syntax for wildcard bind addresses.
       + Enable IPV6_V6ONLY socket option on sshd(8) listen socket, as is
         already done for X11/TCP forwarding sockets (closes: #439661).
       + Fix FD leak that could hang a ssh(1) connection multiplexing master.
       + Make ssh(1) -q option documentation consistent with reality.
       + Fixed sshd(8) PAM support not calling pam_session_close(), or
         failing to call it with root privileges (closes: #372680).
       + Fix activation of OpenSSL engine support when requested in configure
         (LP: #119295).
       + Cache SELinux status earlier so we know if it's enabled after a
         chroot (LP: #237557).
     - 5.1/5.1p1 (
       + Introduce experimental SSH Fingerprint ASCII Visualisation to ssh(1)
         and ssh-keygen(1). Visual fingerprint display is controlled by a new
         ssh_config(5) option "VisualHostKey". The intent is to render SSH
         host keys in a visual form that is amenable to easy recall and
         rejection of changed host keys.
       + sshd_config(5) now supports CIDR address/masklen matching in "Match
         address" blocks, with a fallback to classic wildcard matching.
       + sshd(8) now supports CIDR matching in ~/.ssh/authorized_keys
         from="..." restrictions, also with a fallback to classic wildcard
       + Added an extended test mode (-T) to sshd(8) to request that it write
         its effective configuration to stdout and exit. Extended test mode
         also supports the specification of connection parameters (username,
         source address and hostname) to test the application of
         sshd_config(5) Match rules.
       + ssh(1) now prints the number of bytes transferred and the overall
         connection throughput for SSH protocol 2 sessions when in verbose
         mode (previously these statistics were displayed for protocol 1
         connections only).
       + sftp-server(8) now supports extension methods statvfs at
         and fstatvfs at that implement statvfs(2)-like operations.
       + sftp(1) now has a "df" command to the sftp client that uses the
         statvfs at to produce a df(1)-like display of filesystem
         space and inode utilisation (requires statvfs at support on
         the server).
       + Added a MaxSessions option to sshd_config(5) to allow control of the
         number of multiplexed sessions supported over a single TCP
         connection. This allows increasing the number of allowed sessions
         above the previous default of 10, disabling connection multiplexing
         (MaxSessions=1) or disallowing login/shell/subsystem sessions
         entirely (MaxSessions=0).
       + Added a no-more-sessions at global request extension that
         is sent from ssh(1) to sshd(8) when the client knows that it will
         never request another session (i.e. when session multiplexing is
         disabled). This allows a server to disallow further session requests
         and terminate the session in cases where the client has been
       + ssh-keygen(1) now supports the use of the -l option in combination
         with -F to search for a host in ~/.ssh/known_hosts and display its
       + ssh-keyscan(1) now defaults to "rsa" (protocol 2) keys, instead of
         "rsa1" (LP: #129794).
       + Added an AllowAgentForwarding option to sshd_config(8) to control
         whether authentication agent forwarding is permitted. Note that this
         is a loose control, as a client may install their own unofficial
       + ssh(1) and sshd(8): avoid unnecessary malloc/copy/free when
         receiving network data, resulting in a ~10% speedup.
       + ssh(1) and sshd(8) will now try additional addresses when connecting
         to a port forward destination whose DNS name resolves to more than
         one address. The previous behaviour was to try the only first
         address and give up if that failed.
       + ssh(1) and sshd(8) now support signalling that channels are
         half-closed for writing, through a channel protocol extension
         notification "eow at". This allows propagation of closed
         file descriptors, so that commands such as "ssh -2 localhost od
         /bin/ls | true" do not send unnecessary data over the wire.
       + sshd(8): increased the default size of ssh protocol 1 ephemeral keys
         from 768 to 1024 bits.
       + When ssh(1) has been requested to fork after authentication ("ssh
         -f") with ExitOnForwardFailure enabled, delay the fork until after
         replies for any -R forwards have been seen. Allows for robust
         detection of -R forward failure when using -f.
       + "Match group" blocks in sshd_config(5) now support negation of
         groups. E.g. "Match group staff,!guests".
       + sftp(1) and sftp-server(8) now allow chmod-like operations to set
         set[ug]id/sticky bits.
       + The MaxAuthTries option is now permitted in sshd_config(5) match
       + Multiplexed ssh(1) sessions now support a subset of the ~ escapes
         that are available to a primary connection.
       + ssh(1) connection multiplexing will now fall back to creating a new
         connection in most error cases (closes: #352830).
       + Make ssh(1) deal more gracefully with channel requests that fail.
         Previously it would optimistically assume that requests would always
         succeed, which could cause hangs if they did not (e.g. when the
         server runs out of file descriptors).
       + ssh(1) now reports multiplexing errors via the multiplex slave's
         stderr where possible (subject to LogLevel in the mux master).
       + Fixed an UMAC alignment problem that manifested on Itanium
   * Remove our local version of moduli(5) now that there's one upstream.
   * Say "GTK+" rather than "GTK" in ssh-askpass-gnome's description.
   * Add lintian overrides for empty /usr/share/doc/openssh-client
     directories in openssh-server and ssh (necessary due to being symlink
   * Merge from Ubuntu:
     - Add 'status' action to openssh-server init script, requiring lsb-base
       (>= 3.2-13) (thanks, Dustin Kirkland).
   * debconf template translations:
     - Update Korean (thanks, Sunjae Park; closes: #484821).
 openssh (1:4.7p1-13) unstable; urgency=low
   * Add some helpful advice to the end of ssh-vulnkey's output if there are
     unknown or compromised keys (thanks, Dan Jacobson; closes: #483756).
   * Check compromised key blacklist in ssh or ssh-add, as well as in the
     server (LP: #232391). To override the blacklist check in ssh
     temporarily, use 'ssh -o UseBlacklistedKeys=yes'; there is no override
     for the blacklist check in ssh-add.
   * Add cross-references to ssh-vulnkey(1) to ssh(1), ssh-add(1),
     ssh-keygen(1), and sshd(8) (closes: #484451).
   * Change openssh-client-udeb's Installer-Menu-Item from 99900 to 99999
     (thanks, Frans Pop).
   * Drop openssh-client-udeb isinstallable hack, as main-menu (>= 1.26) now
     takes care of that (thanks, Frans Pop; closes: #484404).
   * Update DEB_BUILD_OPTIONS parsing code from policy 3.8.0.
   * Add documentation on removing openssh-blacklist locally (see #484269).
   * Clarify documentation of SSHD_OOM_ADJUST, and make setting it to the
     empty string actually skip adjustment as intended (closes: #487325).
   * Remove empty /usr/share/applications directory in ssh-askpass-gnome.
   * debconf template translations:
     - Update Romanian (thanks, Cătălin Feștilă; closes: #485415).
