2014-02-09Drop ssh-vulnkeyColin Watson
Drop ssh-vulnkey and the associated ssh/ssh-add/sshd integration code, leaving only basic configuration file compatibility, since it has been nearly six years since the original vulnerability and this code is not likely to be of much value any more. See https://lists.debian.org/debian-devel/2013/09/msg00240.html for my full reasoning.
2014-02-09Various Debian-specific configuration changesColin Watson
ssh: Enable ForwardX11Trusted, returning to earlier semantics which cause fewer problems with existing setups (http://bugs.debian.org/237021). ssh: Set 'SendEnv LANG LC_*' by default (http://bugs.debian.org/264024). ssh: Enable HashKnownHosts by default to try to limit the spread of ssh worms. ssh: Enable GSSAPIAuthentication and disable GSSAPIDelegateCredentials by default. sshd: Refer to /usr/share/doc/openssh-server/README.Debian.gz alongside PermitRootLogin default. Document all of this, along with several sshd defaults set in debian/openssh-server.postinst.

2014-02-09ssh(1): Refer to ssh-argv0(1)Colin Watson
Old versions of OpenSSH (up to 2.5 or thereabouts) allowed creating symlinks to ssh with the name of the host you want to connect to. Debian ships an ssh-argv0 script restoring this feature; this patch refers to its manual page from ssh(1).

2014-02-09Include the Debian version in our identificationMatthew Vernon
This makes it easier to audit networks for versions patched against security vulnerabilities. It has little detrimental effect, as attackers will generally just try attacks rather than bothering to scan for vulnerable-looking version strings. (However, see debian-banner.patch.)

2014-02-09Allow harmless group-writabilityColin Watson
Allow secure files (~/.ssh/config, ~/.ssh/authorized_keys, etc.) to be group-writable, provided that the group in question contains only the file's owner. Rejected upstream for IMO incorrect reasons (e.g. a misunderstanding about the contents of gr->gr_mem). Given that per-user groups and umask 002 are the default setup in Debian (for good reasons - this makes operating in setgid directories with other groups much easier), we need to permit this by default.

2014-02-09Reduce severity of "Killed by signal %d"Peter Samuelson
This produces irritating messages when using ProxyCommand or other programs that use ssh under the covers (e.g. Subversion). These messages are more normally printed by the calling program, such as the shell. According to the upstream bug, the right way to avoid this is to use the -q option, so we may drop this patch after further investigation into whether any software in Debian is still relying on it.

2014-02-09"LogLevel SILENT" compatibilityJonathan David Amery
"LogLevel SILENT" (-qq) was introduced in Debian openssh 1:3.0.1p1-1 to match the behaviour of non-free SSH, in which -q does not suppress fatal errors. However, this was unintentionally broken in 1:4.6p1-2 and nobody complained, so we've dropped most of it. The parts that remain are basic configuration file compatibility, and an adjustment to "Pseudo-terminal will not be allocated ..." which should be split out into a separate patch.

2014-02-09Various keepalive extensionsRichard Kettlewell
Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported in previous versions of Debian's OpenSSH package but since superseded by ServerAliveInterval. (We're probably stuck with this bit for compatibility.) In batch mode, default ServerAliveInterval to five minutes. Adjust documentation to match and to give some more advice on use of keepalives.

2014-02-09Accept obsolete ssh-vulnkey configuration optionsColin Watson
These options were used as part of Debian's response to CVE-2008-0166. Nearly six years later, we no longer need to continue carrying the bulk of that patch, but we do need to avoid failing when the associated configuration options are still present.
