This commit ups the retries for downloading the build-product tarball
to a given remote system from once to five times, the better to handle
transient network failures.

Compressing KASAN vmlinux files reduces torture.sh res file size from
about 100G to about 50G, which is good, but the KCSAN vmlinux files
are also large. Compressing them reduces their size from about 700M to
about 100M (but of course your mileage may vary). This commit therefore
compresses both KASAN and KCSAN vmlinux files.

This commit further improves torture.sh run summaries by indicating
which runs' "Bugs:" counts are all KCSAN reports, and further printing
an additional end-of-run summary line when all errors reported in all
runs were KCSAN reports.

Runs having only KCSAN reports will normally print a summary line
containing only a "Bugs:" entry. However, these bugs might or might
not be KCSAN reports. This commit therefore flags runs in which all the
"Bugs:" entries are KCSAN reports.

Currently, torture.sh lists the failed runs, but it is up to the user
to work out what failed. This is especially annoying for KCSAN runs,
where RCU's tighter definitions result in failures being reported for
other parts of the kernel. This commit therefore outputs "Summary:"
lines for each failed run, allowing the user to more quickly identify
which failed runs need focused attention.

In a clear-cut case of "not thinking big enough", kvm.sh limits the
multipliers for torture-test scenarios to three digits. Although this is
large enough for any single system that I have ever run rcutorture on,
it does become a problem when you want to use kvm-remote.sh to run as
many instances of TREE09 as fit on a set of 20 systems with 80 CPUs each.
Yes, one could simply say "--configs '800*TREE09 800*TREE09'", but this
commit removes the need for that sort of hacky workaround by permitting
four-digit repetition numbers, thus allowing "--configs '1600*TREE09'".
Five-digit repetition numbers remain off the menu. Should they ever
really be needed, they can easily be added!

Console logs can sometimes have trailing control-M characters, which the
forward-progress evaluation code in kvm-recheck-rcu.sh passes through
to the user output. Which does not cause a technical problem, but which
can look ugly. This commit therefore strips the control-M characters.

When cross-building tools with clang, we run `which $(CROSS_COMPILE)gcc`
to detect whether a GCC toolchain provides the standard libraries. It is
only a helper because some distros put libraries where LLVM does not
automatically find them. On other systems, LLVM detects the libc
automatically and does not need this. There, it is completely fine not
to have a GCC at all, but some versions of `which' display an error when
the command is not found:
which: no aarch64-linux-gnu-gcc in ($PATH)
Since the error can safely be ignored, throw it to /dev/null.

This actually adds a new prctl arg, but it has to be dealt with
differently, as it is not in sequence with the other arguments.

This new PR_SET_VMA value isn't in sequence with all the other prctl
arguments and instead uses a big, 0x prefixed hex number: 0x53564d41 (S V M A).
This makes it harder to generate a string table as it would be rather
sparse, so make the regexp more stricter to avoid catching those.
A followup patch for 'perf trace' to cope with such oddities will be
needed, but then its a matter for the next merge window.
The next patch will update the prctl.h file to cope with this perf build

vdso_test_abi contains a batch of tests that verify the validity of the
vDSO ABI.
When a vDSO symbol is not found the relevant test is skipped reporting
KSFT_SKIP. All the tests return values are then added in a single
variable which is checked to verify failures. This approach can have
side effects which result in reporting the wrong kselftest exit status.
Fix vdso_test_abi verifying the return code of each test separately.

If zram-generator package is installed and works, then we can not remove
zram module because zram swap is being used. This case needs a clean zram
environment, change this test by using hot_add/hot_remove interface. So
even zram device is being used, we still can add zram device and remove
them in cleanup.
The two interface was introduced since kernel commit 6566d1a32bf7("zram:
add dynamic device add/remove functionality") in v4.2-rc1. If kernel
supports these two interface, we use hot_add/hot_remove to slove this
problem, if not, just check whether zram is being used or built in, then
skip it on old kernel.

zram01 uses `free -m` to measure zram memory usage. The results are no
sense because they are polluted by all running processes on the system.
We Should only calculate the free memory delta for the current process.
So use the third field of /sys/block/zram<id>/mm_stat to measure memory
usage instead. The file is available since kernel 4.1.
orig_data_size(first): uncompressed size of data stored in this disk.
compr_data_size(second): compressed size of data stored in this disk
mem_used_total(third): the amount of memory allocated for this disk
Also remove useless zram cleanup call in zram_fill_fs and so we don't
need to cleanup zram twice if fails.

Since commit 43209ea2d17a ("zram: remove max_comp_streams internals"), zram
has switched to per-cpu streams. Even kernel still keep this interface for
some reasons, but writing to max_comp_stream doesn't take any effect. So
skip it on newer kernel ie 4.7.
The code that comparing kernel version is from xfstests testsuite ext4/053.

Add a test that sends large udp packet (which is fragmented)
via a stateless nft nat rule, i.e. 'ip saddr set 10.2.3.4'
and check that the datagram is received by peer.
On kernels without

this will fail with:

There is no need for tests other than amx_test to enable dynamic xsave
states. Remove the call to vm_xsave_req_perm from generic code,
and move it inside the test. While at it, allow customizing the bit
that is requested, so that future tests can use it differently.

Don't skip the vmcall() in l2_guest_code() prior to re-entering L2, doing
so will result in L2 running to completion, popping '0' off the stack for
RET, jumping to address '0', and ultimately dying with a triple fault
shutdown.
It's not at all obvious why the test re-enters L2 and re-executes VMCALL,
but presumably it serves a purpose. The VMX path doesn't skip vmcall(),
and the test can't possibly have passed on SVM, so just do what VMX does.

Attempt to write various invalid values for control types we know about and
check that something sensible happens. The ABI isn't quite as clearly
defined as one might like, rather than generating an error when an invalid
value is written many devices will silently rewrite the value into one that
is valid for the control. The exact value chosen is not predictable so in
the case the write succeeds we just check that the value we read back is
one that is valid for the control.

The lirc.h file is an old copy of lirc.h from the kernel sources. It is
out of date, and the bpf lirc tests don't need a new copy anyway. As
long as /usr/include/linux/lirc.h is from kernel v5.2 or newer, the tests
will compile fine.

We have some many cases that will create child process as well, such as
pidfd_wait. Previously, we will signal/kill the parent process when it
is time out, but this signal will not be sent to its child process. In
such case, if child process doesn't terminate itself, ksefltest framework
will hang forever.
Here we group all its child processes so that kill() can signal all of
them in timeout.

Use 'tee' to send the test output to stdout in addition to the current
output file. This makes the output easier to handle in automated test
systems and is superior to only later dumping the output file contents
to stdout, since this way the test output can be interleaved with other
log messages, like from the kernel, so that chronology is preserved,
making it easier to detect issues.

The timeout setting for the rtc kselftest is currently 90 seconds. This
setting is used by the kselftest runner to stop running a test if it
takes longer than the assigned value.
However, two of the test cases inside rtc set alarms. These alarms are
set to the next beginning of the minute, so each of these test cases may
take up to, in the worst case, 60 seconds.
In order to allow for all test cases in rtc to run, even in the worst
case, when using the kselftest runner, the timeout value should be
increased to at least 120. Set it to 180, so there's some additional
slack.
Correct operation can be tested by running the following command right
after the start of a minute (low second count), and checking that all
test cases run:
./run_kselftest.sh -c rtc

On GCC 12, the build fails due to a possible truncated string:
check.c: In function 'validate_call':
check.c:2865:58: error: '%d' directive output may be truncated writing between 1 and 10 bytes into a region of size 9 [-Werror=format-truncation=]
2865 | snprintf(pvname, sizeof(pvname), "pv_ops[%d]", idx);
| ^~
In theory it's a valid bug:
static char pvname[16];
int idx;
...
idx = (rel->addend / sizeof(void *));
snprintf(pvname, sizeof(pvname), "pv_ops[%d]", idx);
There are only 7 chars for %d while it could take up to 9, so the
printed "pv_ops[%d]" string could get truncated.
In reality the bug should never happen, because pv_ops only has ~80
entries, so 7 chars for the integer is more than enough. Still, it's
worth fixing. Bump the buffer size by 2 bytes to silence the warning.
