2020-10-18Force use of DNSSEC even if "options edns0" isn't in resolv.confColin Watson
This allows SSHFP DNS records to be verified if glibc 2.11 is installed. Origin: vendor, https://cvs.fedoraproject.org/viewvc/F-12/openssh/openssh-5.2p1-edns.patch?revision=1.1&view=markup Bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572049 Bug-Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572049 Last-Update: 2010-04-06 Patch-Name: dnssec-sshfp.patch
2020-10-18Look for $SHELL on the path for ProxyCommand/LocalCommandColin Watson
There's some debate on the upstream bug about whether POSIX requires this. I (Colin Watson) agree with Vincent and think it does. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1494 Bug-Debian: http://bugs.debian.org/492728 Last-Update: 2020-02-21 Patch-Name: shell-path.patch

Tweak scp's reporting of filenames in verbose mode to be a bit less confusing with spaces. This should be revised to mimic real shell quoting. Bug-Ubuntu: https://bugs.launchpad.net/bugs/89945 Last-Update: 2010-02-27 Patch-Name: scp-quoting.patch
2020-10-18Allow 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.

2020-10-18"LogLevel SILENT" compatibilityNatalie 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.

2020-10-18Various 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aliases for ProtocolKeepAlives and SetupTimeOut, supported in previous versions of Debian's OpenSSH package but since superseded by ServerAliveInterval.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.

2020-10-18Accept 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
2020-10-18Handle 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: 2020-10-18 Patch-Name: selinux-role.patch
2020-10-18Restore 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: 2019-06-05 Patch-Name: restore-tcp-wrappers.patch
2020-10-18GSSAPI 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.

2020-09-11Move the local m4 macrosSebastian Andrzej Siewior
The `aclocal' step is skipped during `autoreconf' because aclocal.m4 is present. Move the current aclocal.m4 which contains local macros into the m4/ folder. With this change the aclocal.m4 will be re-created during changes to the m4/ macro. This is needed so the `aclocal' can fetch m4 macros from the system if they are references in the configure script. This is a prerequisite to use PKG_CHECK_MODULES. Signed-off-by: Sebastian Andrzej Siewior <sebastian@breakpoint.cc>

BROKEN_MMAP is no longer defined since commit 1cfd5c06efb12 ("Remove portability support for mmap") this commit also removed other HAVE_MMAP user. I didn't find anything that defines HAVE_MMAP. The check does not trigger because compression on server side is by default COMP_DELAYED (2) so it never triggers. Remove remaining HAVE_MMAP and BROKEN_MMAP bits.

2020-08-27upstream: major rework of FIDO token selection logicdjm@openbsd.org
When PINs are in use and multiple FIDO tokens are attached to a host, we cannot just blast requests at all attached tokens with the PIN specified as this will cause the per-token PIN failure counter to increment. If this retry counter hits the token's limit (usually 3 attempts), then the token will lock itself and render all (web and SSH) of its keys invalid. We don't want this. So this reworks the key selection logic for the specific case of multiple keys being attached. When multiple keys are attached and the operation requires a PIN, then the user must touch the key that they wish to use first in order to identify it. This may require multiple touches, but only if there are multiple keys attached AND (usually) the operation requires a PIN. The usual case of a single key attached should be unaffected.
