This is mainly fallout from the original implementation of dynamic CXL region creation (instantiate new physical memory pools) that arrived in v6.0-rc1.

2022-10-28tools/nolibc/string: Fix memcmp() implementationRasmus Villemoes1-2/+2
The C standard says that memcmp() must treat the buffers as consisting of "unsigned chars". If char happens to be unsigned, the casts are ok, but then obviously the c1 variable can never contain a negative value. And when char is signed, the casts are wrong, and there's still a problem with using an 8-bit quantity to hold the difference, because that can range from -255 to +255. For example, assuming char is signed, comparing two 1-byte buffers, one containing 0x00 and another 0x80, the current implementation would return -128 for both memcmp(a, b, 1) and memcmp(b, a, 1), whereas one of those should of course return something positive.

2022-10-28tools/nolibc: Fix missing strlen() definition and infinite loop with gcc-12Willy Tarreau1-5/+8
When built at -Os, gcc-12 recognizes an strlen() pattern in nolibc_strlen() and replaces it with a jump to strlen(), which is not defined as a symbol and breaks compilation. Worse, when the function is called strlen(), the function is simply replaced with a jump to itself, hence becomes an infinite loop. One way to avoid this is to always set -ffreestanding, but the calling code doesn't know this and there's no way (either via attributes or pragmas) to globally enable it from include files, effectively leaving a painful situation for the caller. Alexey suggested to place an empty asm() statement inside the loop to stop gcc from recognizing a well-known pattern, which happens to work pretty fine. At least it allows us to make sure our local definition is not replaced with a self jump. The function only needs to be renamed back to strlen() so that the symbol exists, which implies that nolibc_strlen() which is used on variable strings has to be declared as a macro that points back to it before the strlen() macro is redifined. It was verified to produce valid code with gcc 3.4 to 12.1 at different optimization levels, and both with constant and variable strings. In case this problem surfaces again in the future, an alternate approach consisting in adding an optimize("no-tree-loop-distribute-patterns") function attribute for gcc>=12 worked as well but is less pretty.

2022-10-28KVM: selftests: Mark "guest_saw_irq" as volatile in xen_shinfo_testSean Christopherson1-1/+1
Tag "guest_saw_irq" as "volatile" to ensure that the compiler will never optimize away lookups. Relying on the compiler thinking that the flag is global and thus might change also works, but it's subtle, less robust, and looks like a bug at first glance, e.g. risks being "fixed" and breaking the test. Make the flag "static" as well since convincing the compiler it's global is no longer necessary. Alternatively, the flag could be accessed with {READ,WRITE}_ONCE(), but literally every access would need the wrappers, and eking out performance isn't exactly top priority for selftests.

Tests for races between shinfo_cache (de)activation and hypercall+ioctl() processing. KVM has had bugs where activating the shared info cache multiple times and/or with concurrent users results in lock corruption, NULL pointer dereferences, and other fun. For the timer injection testcase (#22), re-arm the timer until the IRQ is successfully injected. If the timer expires while the shared info is deactivated (invalid), KVM will drop the event.

2022-10-25perf list: Fix PMU name pai_crypto in perf list on s390Thomas Richter1-0/+0
Commit e0b23af82d6f454c ("perf list: Add PMU pai_crypto event description for IBM z16") introduced the "Processor Activity Instrumentation" for cryptographic counters for z16. The PMU device driver exports the counters via sysfs files listed in directory /sys/devices/pai_crypto. To specify an event from that PMU, use 'perf stat -e pai_crypto/XXX/'. However the JSON file mentioned in above commit exports the counter decriptions in file pmu-events/arch/s390/cf_z16/pai.json. Rename this file to pmu-events/arch/s390/cf_z16/pai_crypto.json to make the naming consistent. Now 'perf list' shows the counter names under pai_crypto section: pai_crypto: CRYPTO_ALL [CRYPTO ALL. Unit: pai_crypto] ... Output before was pai: CRYPTO_ALL [CRYPTO ALL. Unit: pai_crypto] ...

2022-10-25perf bpf: Fix build with libbpf 0.7.0 by checking if ↵Arnaldo Carvalho de Melo5-0/+36
bpf_program__set_insns() is available During the transition to libbpf 1.0 some functions that perf used were deprecated and finally removed from libbpf, so bpf_program__set_insns() was introduced for perf to continue to use its bpf loader. But when build with LIBBPF_DYNAMIC=1 we now need to check if that function is available so that perf can build with older libbpf versions, even if the end result is emitting a warning to the user that the use of the perf BPF loader requires a newer libbpf, since bpf_program__set_insns() touches libbpf objects internal state. This affects only 'perf trace' when using bpf C code or pre-compiled bytecode as an event. Noticed on RHEL9, that has libbpf 0.7.0, where bpf_program__set_insns() isn't available.

2022-10-25perf bpf: Fix build with libbpf 0.7.0 by adding prototype for bpf_load_program()Arnaldo Carvalho de Melo1-0/+5
The bpf_load_program() prototype appeared in tools/lib/bpf/bpf.h as deprecated, but nowadays its completely removed, so add it back for building with the system libbpf when using 'make LIBBPF_DYNAMIC=1'. This is a stop gap hack till we do like tools/bpf does with bpftool, i.e. bootstrap the libbpf build and install it in the perf build directory when not using 'make LIBBPF_DYNAMIC=1'. That has to be done to all libraries in tools/lib/, so tha we can remove -Itools/lib/ from the tools/perf CFLAGS. Noticed when building with LIBBPF_DYNAMIC=1 and libbpf 0.7.0 on RHEL9.

2022-10-25perf vendor events power10: Fix hv-24x7 metric eventsKajol Jain1-36/+36
Testcase stat_all_metrics.sh fails in powerpc: 90: perf all metrics test : FAILED! The testcase "stat_all_metrics.sh" verifies perf stat result for all the metric events present in perf list. It runs perf metric events with various commands and expects non-empty metric result. Incase of powerpc:hv-24x7 events, some of the event count can be 0 based on system configuration. And if that event used as denominator in divide equation, it can cause divide by 0 error. The current nest_metric.json file creating divide by 0 issue for some of the metric events, which results in failure of the "stat_all_metrics.sh" test case. Most of the metrics events have cycles or an event which expect to have a larger value as denominator, so adding 1 to the denominator of the metric expression as a fix.

When exporting and running a subset of selftests via kselftest, files from parts of the source tree which were not exported are not available. A few tests are trying to source such files. Address the problem by using symlinks. The problem can be reproduced by running: make -C tools/testing/selftests gen_tar TARGETS="drivers/net/bonding" [... extract archive ...] ./run_kselftest.sh or: make kselftest KBUILD_OUTPUT=/tmp/kselftests TARGETS="drivers/net/bonding" Fixes: bbb774d921e2 ("net: Add tests for bonding and team address list management") Fixes: eccd0a80dc7f ("selftests: net: dsa: add a stress test for unlocked FDB operations") Link: https://lore.kernel.org/netdev/40f04ded-0c86-8669-24b1-9a313ca21076@redhat.com/ Reported-by: Jonathan Toppins <jtoppins@redhat.com> Signed-off-by: Benjamin Poirier <bpoirier@nvidia.com> Reviewed-by: Jonathan Toppins <jtoppins@redhat.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
