For these hooks the true "neutral" value is -EOPNOTSUPP, which is
currently what is returned when no LSM provides this hook and what LSMs
return when there is no security context set on the socket. Correct the
value in <linux/lsm_hooks.h> and adjust the dispatch functions in

In an entirely unrelated discussion where I pointed out a stupid thinko
of mine, Rasmus piped up and noted that that obvious mistake already
existed elsewhere in the kernel tree.

An "error pointer" is the negative error value encoded as a pointer,
making the whole "return error or valid pointer" use-case simple and
straightforward.  We use it all over the kernel.

But the key here is that errors are _negative_ error numbers, not the
horrid UNIX user-level model of "-1 and the value of 'errno'".

The Apple mailbox driver used the positive error values, and thus just
returned invalid normal pointers instead of actual errors.

Of course, the reason nobody ever noticed is that the errors presumably
never actually happen, so this is fixing a conceptual bug rather than an
actual one.

The seccomp benchmark test makes a number of checks on the performance it
measures and logs them to the output but does so in a custom format which
none of the automated test runners understand meaning that the chances that
anyone is paying attention are slim. Let's additionally log each result in
KTAP format so that automated systems parsing the test output will see each
comparison as a test case. The original logs are left in place since they
provide the actual numbers for analysis.

As part of this rework the flow for the main program so that when we skip
tests we still log all the tests we skip, this is because the standard KTAP
headers and footers include counts of the number of expected and run tests.

In preparation for trying to output the test results themselves in TAP
format rework all the prints in the benchmark to use the kselftest output
functions. The uses of system() all produce single line output so we can
avoid having to deal with fully managing the child process and continue to
use system() by simply printing an empty message before we invoke system().
We also leave one printf() used to complete a line of output in place.

The livepatching kselftests rely on comparing expected vs. observed
dmesg output.  After each test, new dmesg entries are determined by the
'comm' utility comparing a saved, pre-test copy of dmesg to post-test
dmesg output.

Alexander reports that the 'comm --nocheck-order -13' invocation used by
the tests can be confused when dmesg entry timestamps vary in magnitude
(ie, "[   98.820331]" vs. "[  100.031067]"), in which case, additional
messages are reported as new.  The unexpected entries then spoil the
test results.

Instead of relying on 'comm' or 'diff' to determine new testing dmesg
entries, refactor the code:

  - pre-test  : log a unique canary dmesg entry
  - test      : run tests, log messages
  - post-test : filter dmesg starting from pre-test message

Even with inplace decompression, sometimes very few temporary buffers
may be still needed for a single decompression shot (e.g. 16 pages for
64k sliding window or 4 pages for 16k sliding window).  In low-memory
scenarios, it would be better to try to allocate with GFP_NOWAIT on
readahead first.  That can help reduce the time spent on page allocation
under durative memory pressure.

Here are detailed performance numbers under multi-app launch benchmark
workload [1] on ARM64 Android devices (8-core CPU and 8GB of memory)
running a 5.15 LTS kernel with EROFS of 4k pclusters:

+----------------------------------------------+
|      LZ4       | vanilla | patched |  diff   |
|----------------+---------+---------+---------|
|  Average (ms)  |  3364   |  2684   | -20.21% | [64k sliding window]
|----------------+---------+---------+---------|
|  Average (ms)  |  2079   |  1610   | -22.56% | [16k sliding window]
+----------------------------------------------+

The total size of system images for 4k pclusters is almost unchanged:
(64k sliding window)  9,117,044 KB
(16k sliding window)  9,113,096 KB

Therefore, in addition to switch the sliding window from 64k to 16k,
after applying this patch, it can eventually save 52.14% (3364 -> 1610)
on average with no memory reservation.  That is particularly useful for
embedded devices with limited resources.

     AMD P-state cpufreq driver (Mario Limonciello)

   - Make the intel_pstate cpufreq driver avoid unnecessary computation
     of the HWP performance level corresponding to a given frequency in
     the cases when it is known already, which also helps to avoid
     reducing the maximum CPU capacity artificially on some systems
     (Rafael J. Wysocki)

   - Fix compilation of the cpupower utility when CFLAGS is passed as a
     make argument for cpupower, but it does not take effect as expected
     due to mishandling (Stanley Chan)"

The inode_getsecctx LSM hook has previously been corrected to have
-EOPNOTSUPP instead of 0 as the default return value to fix BPF LSM
behavior. However, the call_int_hook()-generated loop in
security_inode_getsecctx() was left treating 0 as the neutral value, so
after an LSM returns 0, the loop continues to try other LSMs, and if one
of them returns a non-zero value, the function immediately returns with
said value. So in a situation where SELinux and the BPF LSMs registered
this hook, -EOPNOTSUPP would be incorrectly returned whenever SELinux
returned 0.

Fix this by open-coding the call_int_hook() loop and making it use the
correct LSM_RET_DEFAULT() value as the neutral one, similar to what
other hooks do.
