The tv argument to the settimeofday syscall is allowed to be NULL, if

The settimeofday syscall accepts a tz argument indicating the desired
timezone to the kernel. QEMU previously ignored any argument provided
by the target program & always passed NULL to the kernel. Instead,
translate the argument & pass along the data userland provided.
Although this argument is described by the settimeofday man page as
obsolete, it is used by systemd as of version 213.

Calls to the mount syscall can legitimately provide NULL as the value
for the source of filesystemtype arguments, which QEMU would previously
reject & return -EFAULT to the target program. An example of this is
remounting an already mounted filesystem with different properties.
Instead of rejecting such syscalls with -EFAULT, pass NULL along to the
kernel as the target program expects.
Additionally this patch fixes a potential memory leak when DEBUG_REMAP
is enabled and lock_user_string fails on the target or filesystemtype
arguments but a prior argument was non-NULL and already locked.
Since the patch already touched most lines of the TARGET_NR_mount case,
it fixes the indentation & coding style for good measure.

QEMU previously passed the result of the host syscall directly to the

representations of socket types, as is the case when running a MIPS
target program on an x86 host. Introduce a host_to_target_sock_type

iotest 083 filters out debug messages from nbd, which are prefixed (and
recognized) by __FILE__. However, the current filter (/^nbd\.c…/) is
valid for in-tree builds only, as out-of-tree builds will have a path
before that filename (e.g. "/tmp/qemu/nbd.c"). Fix this by adding .*
before "nbd\.c".
While working on this, also fix the regexes: '.' should be escaped and a
single backslash is not enough for escaping when enclosed by double
quotes.

As out-of-tree builds are preferred for qemu, running the qemu-iotests
in that out-of-tree build should be supported as well. To do so, a
symbolic link has to be created pointing to the check script in the
source directory. That script will check whether it has been run through
a symlink, and if so, will assume it is run in the build tree. All
output and temporary operations performed by iotests are then redirected
here and, unless specified otherwise by the user, QEMU_PROG etc. will be
set to paths appropriate for the build tree.
Also, drop making every test case executable if it is not yet, as this
would modify the source tree which is not desired for out-of-tree runs
and should be fixed in the repository anyway.
