2020-06-07Add DebianBanner server configuration optionKees Cook
Setting this to "no" causes sshd to omit the Debian revision from its initial protocol handshake, for those scared by package-versioning.patch. Bug-Debian: http://bugs.debian.org/562048 Forwarded: not-needed Last-Update: 2020-06-07 Patch-Name: debian-banner.patch
2020-06-07Include 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.)

2020-06-07Force 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.

2020-06-07Look 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
2020-06-07Adjust scp quoting in verbose modeNicolas Valcárcel
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
2020-06-07Allow 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.

2020-06-07"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.

2020-06-07Various 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. Author: Ian Jackson <ian@chiark.greenend.org.uk> Author: Matthew Vernon <matthew@debian.org> Author: Colin Watson <cjwatson@debian.org> Last-Update: 2020-02-21 Patch-Name: keepalive-extensions.patch
2020-06-07Accept 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
2020-06-07Handle 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: 2020-02-21 Patch-Name: selinux-role.patch
2020-06-07Restore 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
2020-06-07GSSAPI 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.

2020-05-14prefer ln to cp for temporary copy of sshdDamien Miller
I saw failures on the reexec fallback test on Darwin 19.4 where fork()ed children of a process that had it's executable removed would instantly fail. Using ln to preserve the inode avoids this.

2020-05-13explicitly manage .depend and .depend.bakDamien Miller
Bring back removal of .depend to give the file a known state before running makedepend, but manually move aside the current .depend file and restore it as .depend.bak afterwards so the stale .depend check works as expected.

2020-05-13revert removal of .depend before makedependDamien Miller
Commit 83657eac4 started removing .depend before running makedepend to reset the contents of .depend to a known state. Unfortunately this broke the depend-check step as now .depend.bak would only ever be created as an empty file. ok dtucker

2020-05-01Use LONG_LONG_MAX and friends if available.Darren Tucker
If we don't have LLONG_{MIN,MAX} but do have LONG_LONG_{MIN,MAX} then use those instead. We do calculate these values in configure, but it turns out that at least one compiler (old HP ANSI C) can't parse "-9223372036854775808LL" without mangling it. (It can parse "-9223372036854775807LL" which is presumably why its limits.h defines LONG_LONG_MIN as the latter minus 1.) Fixes rekey test when compiled with the aforementioned compiler.

2020-05-01See if SA_RESTART signals will interrupt select().Darren Tucker
On some platforms (at least older HP-UXes such as 11.11, possibly others) setting SA_RESTART on signal handers will cause it to not interrupt select(), at least for calls that do not specify a timeout. Try to detect this and if found, don't use SA_RESTART. POSIX says "If SA_RESTART has been set for the interrupting signal, it is implementation-dependent whether select() restarts or returns with [EINTR]" so this behaviour is within spec.
