The selftests depend on using the shell exit code as a mean of
detecting the success or failure of test-binary executed. The
appropiate output "[PASS]" or "[FAIL]" in generated by
tools/testing/selftests/lib.mk.
Notice that the exit code is masked with 255. Thus, be careful if
using the number of errors as the exit code, as 256 errors would be
seen as a success.
There are two standard defined exit(3) codes:
/usr/include/stdlib.h
#define EXIT_FAILURE 1 /* Failing exit status. */
#define EXIT_SUCCESS 0 /* Successful exit status. */
Fix test_verifier.c to not use the negative value of variable
"results", but instead return EXIT_FAILURE.
Fix test_align.c and test_progs.c to actually use exit codes, before
they were always indicating success regardless of results.

rcu_sched_ctrlblk and rcu_bh_ctrlblk to be in tiny_plugin.h, so this

The CONFIG_RCU_NOCB_CPU_ALL, CONFIG_RCU_NOCB_CPU_NONE, and
CONFIG_RCU_NOCB_CPU_ZERO Kconfig options are used only in testing and
are redundant with the rcu_nocbs= boot parameter. This commit therefore

The PROVE_RCU_REPEATEDLY Kconfig option was initially added due to
the volume of messages from PROVE_RCU: Doing just one per boot would
have required excessive numbers of boots to locate them all. However,
PROVE_RCU messages are now relatively rare, so there is no longer any
reason to need more than one such message per boot. This commit therefore
removes the PROVE_RCU_REPEATEDLY Kconfig option.

The RCU_TORTURE_TEST_SLOW_PREINIT, RCU_TORTURE_TEST_SLOW_PREINIT_DELAY,
RCU_TORTURE_TEST_SLOW_PREINIT_DELAY, RCU_TORTURE_TEST_SLOW_INIT,
RCU_TORTURE_TEST_SLOW_INIT_DELAY, RCU_TORTURE_TEST_SLOW_CLEANUP,
and RCU_TORTURE_TEST_SLOW_CLEANUP_DELAY Kconfig options are only
useful for torture testing, and there are the rcutree.gp_cleanup_delay,
rcutree.gp_init_delay, and rcutree.gp_preinit_delay kernel boot parameters
that rcutorture can use instead. The effect of these parameters is to
artificially slow down grace period initialization and cleanup in order
to make some types of race conditions happen more often.
This commit therefore simplifies Tree RCU a bit by removing the Kconfig
options and adding the corresponding kernel parameters to rcutorture's
.boot files instead. However, this commit also leaves out the kernel
parameters for TREE02, TREE04, and TREE07 in order to have about the
same number of tests slowed as not slowed. TREE01, TREE03, TREE05,
and TREE06 are slowed, and the rest are not slowed.

I noticed that test_l4lb was failing in selftests:
# ./test_progs
test_pkt_access:PASS:ipv4 77 nsec
test_pkt_access:PASS:ipv6 44 nsec
test_xdp:PASS:ipv4 2933 nsec
test_xdp:PASS:ipv6 1500 nsec
test_l4lb:PASS:ipv4 377 nsec
test_l4lb:PASS:ipv6 544 nsec
test_l4lb:FAIL:stats 6297600000 200000
test_tcp_estats:PASS: 0 nsec
Summary: 7 PASSED, 1 FAILED
Tracking down the issue actually revealed that endianness selection
in bpf_endian.h is broken when compiled with clang with bpf target.
test_pkt_access.c, test_l4lb.c is compiled with __BYTE_ORDER as
__BIG_ENDIAN, test_xdp.c as __LITTLE_ENDIAN! test_l4lb noticeably
fails, because the test accounts bytes via bpf_ntohs(ip6h->payload_len)
and bpf_ntohs(iph->tot_len), and compares them against a defined
value and given a wrong endianness, the test outcome is different,
of course.
Turns out that there are actually two bugs: i) when we do __BYTE_ORDER
comparison with __LITTLE_ENDIAN/__BIG_ENDIAN, then depending on the
include order we see different outcomes. Reason is that __BYTE_ORDER
is undefined due to missing endian.h include. Before we include the
asm/byteorder.h (e.g. through linux/in.h), then __BYTE_ORDER equals
__LITTLE_ENDIAN since both are undefined, after the include which
correctly pulls in linux/byteorder/little_endian.h, __LITTLE_ENDIAN
is defined, but given __BYTE_ORDER is still undefined, we match on
__BYTE_ORDER equals to __BIG_ENDIAN since __BIG_ENDIAN is also
undefined at that point, sigh. ii) But even that would be wrong,
since when compiling the test cases with clang, one can select between
bpfeb and bpfel targets for cross compilation. Hence, we can also not
rely on what the system's endian.h provides, but we need to look at
the compiler's defined endianness. The compiler defines __BYTE_ORDER__,
and we can match __ORDER_LITTLE_ENDIAN__ and __ORDER_BIG_ENDIAN__,
which also reflects targets bpf (native), bpfel, bpfeb correctly,
thus really only rely on that. After patch:
# ./test_progs
test_pkt_access:PASS:ipv4 74 nsec
test_pkt_access:PASS:ipv6 42 nsec
test_xdp:PASS:ipv4 2340 nsec

Currently, when running from a git archive, the testid.txt file contains
only the branch name, the output of "git status", and the SHA-1 of
the current HEAD. This is useful, but does not uniquely identify the
source code that was built. This commit therefore adds the output of
"git diff HEAD", which means that if two testid.txt files compare equal,
they correspond to exactly the same source code. Give or take the
possibility of SHA-1 collisions, that is. ;-)

The rcutorture scripting handles the CONFIG_*_TORTURE_TEST Kconfig
options specially, and therefore greps them out of the Kconfig-fragment
files. Unfortunately, a poor choice of grep pattern means that the
CONFIG_RCU_TORTURE_TEST_SLOW_CLEANUP, CONFIG_RCU_TORTURE_TEST_SLOW_INIT,
and CONFIG_RCU_TORTURE_TEST_SLOW_PREINIT Kconfig options are also grepped
out, preventing rcutorture from using them. This commit therefore fixes
the offending grep pattern to focus only on the CONFIG_*_TORTURE_TEST
Kconfig options.

A robust combination of paranoia and cowardice has resulted in retaining
Classic SRCU (CONFIG_CLASSIC_SRCU) as a backup for the shiny new Tiny

course needs to be tested. This commit therefore adds an rcutorture
scenario named SRCU-C for Classic SRCU. This commit also adds this

Kconfig "select" clauses can defeat Kconfig-fragment file attempts to

This commit adds a test for a three-level srcu_node tree for Tree SRCU
