Setting this to "no" causes sshd to omit the Debian revision from its
initial protocol handshake, for those scared by package-versioning.patch.

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.)

There's some debate on the upstream bug about whether POSIX requires this.
I (Colin Watson) agree with Vincent and think it does.

Tweak scp's reporting of filenames in verbose mode to be a bit less

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.

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.

"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.

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in previous versions of Debian's OpenSSH package but since superseded by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.

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.

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.

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.

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.

Allow clock_gettime syscall with X32 bit masked off. Apparently
this is required for at least some kernel versions. bz#2142
Patch mostly by Colin Watson. ok dtucker@

This stops the SC_ALLOW(), SC_ALLOW_ARG() and SC_DENY() macros
prepending __NR_ to the syscall number parameter and just makes
them explicit in the macro invocations.

Syscall arguments are passed via an array of 64-bit values in struct
seccomp_data, but we were only inspecting the bottom 32 bits and not
even those correctly for BE systems.
Fortunately, the only case argument inspection was used was in the
socketcall filtering so using this for sandbox escape seems
impossible.
