Fix overly-conservative overflow checks on mulitplications and add checks
on additions. This allows scan_scaled to work up to +/-LLONG_MAX (LLONG_MIN
will still be flagged as a range error). ok millert@
If running with privsep (mandatory now) as a non-privileged user, we
don't chroot or change to an unprivileged user however we still checked
the existence of the user and directory. Don't do those checks if we're
not going to use them. Based in part on a patch from Lionel Fourquaux
via Corinna Vinschen, ok djm@
remove /usr/bin/time calls around tests, makes diffing test
runs harder. Based on patch from Mike Frysinger

Fix segfault when sshd attempts to load RSA1 keys (can

Mark the sshd_config UsePrivilegeSeparation option as
deprecated, effectively making privsep mandatory in sandboxing mode. ok

(note: this doesn't remove the !privsep code paths, though that will
happen eventually).

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.
No binary change in stripped object file before/after.
Check for integer overflow when parsing times in
convtime(). Reported by nicolas.iooss at m4x.org, ok djm@

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.

keys when any of the ssh-rsa-sha2-* methods was enabled in HostkeyAlgorithms
