The sizes of vmlinux files built with KASAN enabled can approach a full
gigabyte, which can result in disk overflow sooner rather than later.
Fortunately, the xz command compresses them by almost an order of
magnitude. This commit therefore uses xz to compress vmlinux file built
by torture.sh with KASAN enabled.
However, xz is not the fastest thing in the world. In fact, it is way
slower than rotating-rust mass storage. This commit therefore also adds a
--compress-kasan-vmlinux argument to specify the degree of xz concurrency,
which defaults to using all available CPUs if there are that many files in
need of compression.

In 2020, running KCSAN often requires careful choice of compiler.
This commit therefore adds a --kcsan-kmake-arg parameter to torture.sh
to allow specifying (for example) "CC=clang" to the kernel build process
to correctly build a KCSAN-enabled kernel.

This commit adds --configs-rcutorture, --configs-locktorture, and
--configs-scftorture arguments to torture.sh, allowing the desired

Users are encouraged to create scripts that provide appropriate settings
for their specific systems.

The bash "eval" command enables Bobby Tables attacks, which might not
be a concern in torture testing by themselves, but one could imagine
these combined with a cut-and-paste attack. This commit therefore gets
rid of them. This comes at a price in terms of bash quoting not working
nicely, so the "--bootargs" argument lists are now passed to torture_one
via a bash-variable side channel. This might be a bit ugly, but it will
also allow torture.sh to grow its own --bootargs parameter.
While in the area, add proper header comments for the bash functions.

Although tailoring a specific set of kvm.sh runs has served rcutorture
testing well over many years, it requires a relatively distraction-free
environment, which is not always available. This commit therefore
adds a prototype torture.sh script that by default tortures pretty much
everything the rcutorture scripting is designed to torture, and which
can be given command-line arguments to take a more focused approach.

For older glibc ~2.17, #include'ing both linux/if.h and net/if.h
fails due to complaints about redefinition of interface flags:
CC net.o
In file included from net.c:13:0:
/usr/include/linux/if.h:71:2: error: redeclaration of enumerator ‘IFF_UP’
IFF_UP = 1<<0, /* sysfs */
^
/usr/include/net/if.h:44:5: note: previous definition of ‘IFF_UP’ was here
IFF_UP = 0x1, /* Interface is up. */
The issue was fixed in kernel headers in [1], but since compilation
of net.c picks up system headers the problem can recur.
Dropping #include <linux/if.h> resolves the issue and it is
not needed for compilation anyhow.

The kernel image can contain multiple types (structs/unions)
with the same name. This causes distinct type hierarchies in
BTF data and makes resolve_btfids fail with error like:
BTFIDS vmlinux
FAILED unresolved symbol udp6_sock
as reported by Qais Yousef [1].
This change adds warning when multiple types of the same name
are detected:
BTFIDS vmlinux
WARN: multiple IDs found for 'file': 526, 113351 - using 526
WARN: multiple IDs found for 'sk_buff': 2744, 113958 - using 2744
We keep the lower ID for the given type instance and let the
build continue.
Also changing the 'nr' variable name to 'nr_types' to avoid confusion.

Currently, if a scenario is repeated as in "--configs '4*TREE01'",
the Kconfig analysis is performed for each occurrance (four times in
this example) and each analysis places the exact same data into the
exact same files. This is not really an issue in this repetition-four
example, but it can needlessly consume tens of seconds of wallclock time
for something like "--config '128*TINY01'".
This commit therefore does Kconfig analysis only once per set of
repeats of a given scenario, courtesy of the "sort -u" command and an
automatically generated awk script.
While in the area, this commit also wordsmiths a comment.

Normally, kvm-recheck.sh is run from kvm.sh, which provides the
TORTURE_TRUST_MAKE environment variable that, if a non-empty string,
indicates that the --trust-make command-line parameter has been passed
to kvm.sh. If there was no --trust-make, kvm-recheck.sh insists
that the Make.out file contain at least one "CC" command. Thus, when
kvm-recheck.sh is run standalone to evaluate a prior --trust-make run,
it will incorrectly insist that a proper kernel build did not happen.
This commit therefore causes kvm-recheck.sh to also search the "log"
file in the top-level results directory for the string "--trust-make".

Commit 757055ae8ded ("init/console: Use ttynull as a fallback when
there is no console") results in the string "Warning: Failed to add
ttynull console. No stdin, stdout, and stderr for the init process!"
appearing on the console, which the rcutorture scripting interprets as
a warning, which causes every rcutorture run to be flagged. However,
the rcutorture init process never attempts to do any I/O, and thus does
not care that it has no stdin, stdout, or stderr.
This commit therefore causes the rcutorture scripting to ignore this

This commit changes the "STOP" file that is used to cleanly halt a running
rcutorture run to "STOP.1" because no scenario directory will ever end
with ".1". If there really was a scenario named "STOP", its directories
would instead be named "STOP", "STOP.2", "STOP.3", and so on. While in
the area, the commit also changes the kernel-run-time checks for this
file to look directly in the directory above $resdir, thus avoiding the
need to pass the TORTURE_STOPFILE environment variable to remote systems.

covering all of the scenarios.

When all of the remote systems have the same number of CPUs, one
approach is to use one "--buildonly" run and one "--dryrun sched" run,
and then distributing the batches out one per remote system. However,

adds a "--dryrun batches" that provides the same information in easily

By default, the "panic" kernel parameter is zero, which causes the kernel
to loop indefinitely after a panic(). The rcutorture scripting will
eventually kill the corresponding qemu process, but only after waiting
for the full run duration plus a few minutes. This works, but delays
notifying the developer of the failure.
This commit therefore causes the rcutorture scripting to pass the
"panic=-1" kernel parameter, which caused the kernel to instead
unceremoniously shut down immediately. This in turn causes qemu to
terminate, so that if all of the runs in a given batch panic(), the
rcutorture scripting can immediately proceed to the next batch.

Currently, passing something like "--kconfig CONFIG_NR_CPUS=2" to kvm.sh

Given that kvm.sh in invoked from scripts, it is only natural for
different levels of scripting to provide their own Kconfig option values,

The rcutorture scripts' identify_qemu_vcpus() function expects `lscpu`
to have a "CPU: " line, for example:
CPU(s): 8
But different local language settings can give different results:

As a result, identify_qemu_vcpus() may return an empty string, resulting
in the following warning (with the same local language settings):

This commit therefore changes identify_qemu_vcpus() to use getconf,

Distributed execution of rcutorture is eased if the qemu execution can

The BPF selftests have build time dependencies on cutting edge versions
of tools in the BPF ecosystem including LLVM which are more involved
to satisfy than more typical requirements like installing a package from
your distribution. This causes issues for users looking at kselftest in
as a whole who find that a default build of kselftest fails and that
resolving this is time consuming and adds administrative overhead. The
fast pace of BPF development and the need for a full BPF stack to do
substantial development or validation work on the code mean that people
working directly on it don't see a reasonable way to keep supporting
older environments without causing problems with the usability of the
BPF tests in BPF development so these requirements are unlikely to be
relaxed in the immediate future.
There is already support for skipping targets so in order to reduce the
barrier to entry for people interested in kselftest as a whole let's use
that to skip the BPF tests by default when people work with the top
level kselftest build system. Users can still build the BPF selftests
as part of the wider kselftest build by specifying SKIP_TARGETS,
including setting an empty SKIP_TARGETS to build everything. They can
also continue to build the BPF selftests individually in cases where
they are specifically focused on BPF.
This isn't ideal since it means people will need to take special steps
to build the BPF tests but the dependencies mean that realistically this
is already the case to some extent and it makes it easier for people to
pick up and work with the other selftests which is hopefully a net win.
