* [930dba8] Combat test failures with a world-writeable socket directory.
On Linux systems libqb uses abstract sockets by default, which lack
access control. However, they aren't available on other platforms.
The other option is using file system sockets, by default under
/var/run. This directory is only writable by root, though, which
makes it inapproriate for unprivileged applications. So use /tmp
instead.

Title:
aarch64 clock_gettime with CLOCK_REALTIME_COARSE or
CLOCK_MONOTONIC_COARSE fails with SIGBUS or SIGSEGV
Status in libqb package in Ubuntu:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Bug description:
The aarch64 vDSO __kernel_clock_gettime implementation crashes when
clock_gettime is called with CLOCK_MONOTONIC_COARSE or
CLOCK_REALTIME_COARSE, with a SIGSEGV or SIGBUS respectively.
In the implementation
(http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/kernel/vdso/gettimeofday.S#n89)
a value other than CLOCK_REALTIME or CLOCK_MONOTONIC branches past the
usual "mov x2, x30" which preserves lr for return later. Anything
other than CLOCK_REALTIME_COARSE and CLOCK_MONOTONIC_COARSE then
branches directly to the svc call, which correctly returns to the
caller. But CLOCK_REALTIME_COARSE and CLOCK_MONOTONIC_COARSE execute
the special coarse path then fall through to the normal
CLOCK_REALTIME/CLOCK_MONOTONIC path, which does a 'ret x2' at the end,
despite not having saved x30 to x2 in the _COARSE case. So it ends up
setting pc to clk_id, which is either 4 or 5, giving a translation or
alignment fault.
