We should try avoiding that perf.h header, it includes way too much
stuff, making it difficult to use things like setting _GNU_SOURCE only
on a small set of headers.

The tools so far have been using the strerror_r() GNU variant, that
returns a string, be it the buffer passed or something else.
But that, besides being tricky in cases where we expect that the
function using strerror_r() returns the error formatted in a provided
buffer (we have to check if it returned something else and copy that
instead), breaks the build on systems not using glibc, like Alpine
Linux, where musl libc is used.
So, introduce yet another wrapper, str_error_r(), that has the GNU
interface, but uses the portable XSI variant of strerror_r(), so that
users rest asured that the provided buffer is used and it is what is
returned.

This script helps to create bonding network devices based on synthetic NIC
(the virtual network adapter usually provided by Hyper-V) and the matching
VF NIC (SRIOV virtual function). So the synthetic NIC and VF NIC can
function as one network device, and fail over to the synthetic NIC if VF is
down.
Mayjor distros (RHEL, Ubuntu, SLES) supported by Hyper-V are supported by
this script.

For the last process to close a file opened for write, function
gfs2_rsqa_delete was deleting the file's inode's block reservation
out of the rgrp reservations tree. Then it was checking to make sure
rs_free was 0, but it was performing the check outside the protection
of rd_rsspin spin_lock. The rd_rsspin spin_lock protection is needed
to prevent a race between the process freeing the reservation and
another who is allocating a new set of blocks inside the same rgrp
for the same inode, thus changing its value.

Fix a number of bugs that appeared when support for mediabus formats was
added:
- Support for V4L2_DV_RGB_RANGE_FULL/LIMITED should only be enabled
for HDMI RGB formats, not for YCbCr formats. Since, as the name
says, this setting is for RGB only. So read the InfoFrame to check
the format.
- the quantization range for the pixelport depends on whether the
mediabus code is RGB or not: if it is RGB, then produce full range
RGB values, otherwise produce limited range YCbCr values.
This means that the op_656_range and alt_data_sat fields of the
platform data are no longer used and these will be removed in a
following patch.
- when setting up a new format the RGB quantization range settings
were never updated. Do so, since this depends on the format.
- fix the log_status output which was confusing and incorrect.

Commit 1fb69bfd29e4b2e5e93922105326dd6cbd5ef6eb (adv7511: improve
colorspace handling) introduced a number of bugs, specifically with
regards to YCbCr output and quantization range handling:
- if the output is not RGB, then disable the full-to-limited range
CSC matrix since that is meant for RGB formats. YCbCr formats are
always limited range, so there is nothing to convert. (OK, full
range YCbCr is possible, but we don't support that right now).
- the mediabus code that was passed to adv7511_set_fmt was always cleared
by the memset in adv7511_fill_format. This made it effectively impossible
to select YCbCr output.
- adv7511_set_fmt never updated the rgb quantization range.

When disconnecting the usbtv device, the sound card is unregistered
from ALSA and the snd member of the usbtv struct is set to NULL. If
the usbtv snd_trigger work is running, this can cause a race condition
where the kernel will attempt to access free'd resources, shown in
[1].
This patch fixes the disconnection code by cancelling any snd_trigger
work before unregistering the sound card from ALSA and checking that
the snd member still exists in the work function.

When proc_pid_attr_write() was changed to use memdup_user apparmor's
(interface violating) assumption that the setprocattr buffer was always
a single page was violated.
The size test is not strictly speaking needed as proc_pid_attr_write()
will reject anything larger, but for the sake of robustness we can keep
it in.
SMACK and SELinux look safe to me, but somebody else should probably
have a look just in case.
Based on original patch from Vegard Nossum <vegard.nossum@oracle.com>

While using AppArmor, SYS_CAP_RESOURCE is insufficient to call prlimit
on another task. The only other example of a AppArmor mediating access to
another, already running, task (ignoring fork+exec) is ptrace.
The AppArmor model for ptrace is that one of the following must be true:
1) The tracer is unconfined
2) The tracer is in complain mode
3) The tracer and tracee are confined by the same profile
4) The tracer is confined but has SYS_CAP_PTRACE
1), 2, and 3) are already true for setrlimit.
We can match the ptrace model just by allowing CAP_SYS_RESOURCE.
We still test the values of the rlimit since it can always be overridden
using a value that means unlimited for a particular resource.
