2016-03-21Reduce 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. Author: Colin Watson <cjwatson@debian.org> Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1118 Bug-Debian: http://bugs.debian.org/313371 Last-Update: 2013-09-14 Patch-Name: quieter-signals.patch
2016-03-21"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.

2016-03-21Various 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aliases for ProtocolKeepAlives and SetupTimeOut, supported in previous versions of Debian's OpenSSH package but since superseded by ServerAliveInterval.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.

2016-03-21Accept 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. Last-Update: 2014-02-09 Patch-Name: ssh-vulnkey-compat.patch
2016-03-21Handle SELinux authorisation rolesManoj Srivastava
Rejected upstream due to discomfort with magic usernames; a better approach will need an SSH protocol change. In the meantime, this came from Debian's SELinux maintainer, so we'll keep it until we have something better. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1641 Bug-Debian: http://bugs.debian.org/394795 Last-Update: 2015-08-19 Patch-Name: selinux-role.patch
2016-03-21Restore TCP wrappers supportColin Watson
Support for TCP wrappers was dropped in OpenSSH 6.7. See this message and thread: https://lists.mindrot.org/pipermail/openssh-unix-dev/2014-April/032497.html It is true that this reduces preauth attack surface in sshd. On the other hand, this support seems to be quite widely used, and abruptly dropping it (from the perspective of users who don't read openssh-unix-dev) could easily cause more serious problems in practice. It's not entirely clear what the right long-term answer for Debian is, but it at least probably doesn't involve dropping this feature shortly before a freeze. Forwarded: not-needed Last-Update: 2014-10-07 Patch-Name: restore-tcp-wrappers.patch
2016-03-21GSSAPI key exchange supportSimon Wilkinson
This patch has been rejected upstream: "None of the OpenSSH developers are in favour of adding this, and this situation has not changed for several years. This is not a slight on Simon's patch, which is of fine quality, but just that a) we don't trust GSSAPI implementations that much and b) we don't like adding new KEX since they are pre-auth attack surface. This one is particularly scary, since it requires hooks out to typically root-owned system resources." However, quite a lot of people rely on this in Debian, and it's better to have it merged into the main openssh package rather than having separate -krb5 packages (as we used to have). It seems to have a generally good security history. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1242 Last-Updated: 2016-03-21 Patch-Name: gssapi.patch

2016-02-23Disable tests where fs perms are incorrectDamien Miller
Some tests have strict requirements on the filesystem permissions for certain files and directories. This adds a regress/check-perm tool that copies the relevant logic from sshd to exactly test the paths in question. This lets us skip tests when the local filesystem doesn't conform to our expectations rather than continuing and failing the test run. ok dtucker@
