2024-09-05pm:cpupower: Add missing powercap_set_enabled() stub functionJohn B. Wyatt IV
There was a symbol listed in the powercap.h file that was not implemented. Implement it with a stub return of 0. Programs like SWIG require that functions that are defined in the headers be implemented.

2024-09-04selftests: mm: make protection_keys test work on arm64Joey Gouly
The encoding of the pkey register differs on arm64, than on x86/ppc. On those platforms, a bit in the register is used to disable permissions, for arm64, a bit enabled in the register indicates that the permission is allowed. This drops two asserts of the form: assert(read_pkey_reg() <= orig_pkey_reg); Because on arm64 this doesn't hold, due to the encoding. The pkey must be reset to both access allow and write allow in the signal handler. pkey_access_allow() works currently for PowerPC as the PKEY_DISABLE_ACCESS and PKEY_DISABLE_WRITE have overlapping bits set. Access to the uc_mcontext is abstracted, as arm64 has a different structure.

2024-09-03selftests: netfilter: nft_queue.sh: fix spurious timeout on debug kernelFlorian Westphal
The sctp selftest is very slow on debug kernels. Its possible that the nf_queue listener program exits due to timeout before first sctp packet is processed. In this case socat hangs until script times out. Fix this by removing the -t option where possible and kill the test program once the file transfer/socat has exited. -t sets SO_RCVTIMEO, its inteded for the 'ping' part of the selftest where we want to make sure that packets get reinjected properly without skipping a second queue request. While at it, add a helper to compare the (binary) files instead of diff. The 'diff' part was copied from a another sub-test that compares text. Let helper dump file sizes on error so we can see the progress made. Tested on an old 2010-ish box with a debug kernel and 100 iterations. This is a followup to the earlier filesize reduction change.

The 32-bit arm build system will complain: tools/perf/util/python.c:75:28: error: field ‘sample’ has incomplete type 75 | struct perf_sample sample; However, arm64 build system doesn't complain this. The root cause is arm64 define "HAVE_KVM_STAT_SUPPORT := 1" in tools/perf/arch/arm64/Makefile, but arm arch doesn't define this. This will lead to kvm-stat.h include other header files on arm64 build system, especially "util/sample.h" for util/python.c.

2024-09-02perf lock contention: Fix spinlock and rwlock accountingNamhyung Kim
The spinlock and rwlock use a single-element per-cpu array to track current locks due to performance reason. But this means the key is always available and it cannot simply account lock stats in the array because some of them are invalid. In fact, the contention_end() program in the BPF invalidates the entry by setting the 'lock' value to 0 instead of deleting the entry for the hashmap. So it should skip entries with the lock value of 0 in the account_end_timestamp(). Otherwise, it'd have spurious high contention on an idle machine: $ sudo perf lock con -ab -Y spinlock sleep 3 contended total wait max wait avg wait type caller 8 4.72 s 1.84 s 590.46 ms spinlock rcu_core+0xc7 8 1.87 s 1.87 s 233.48 ms spinlock process_one_work+0x1b5 2 1.87 s 1.87 s 933.92 ms spinlock worker_thread+0x1a2 3 1.81 s 1.81 s 603.93 ms spinlock tmigr_update_events+0x13c 2 1.72 s 1.72 s 861.98 ms spinlock tick_do_update_jiffies64+0x25 6 42.48 us 13.02 us 7.08 us spinlock futex_q_lock+0x2a 1 13.03 us 13.03 us 13.03 us spinlock futex_wake+0xce 1 11.61 us 11.61 us 11.61 us spinlock rcu_core+0xc7 I don't believe it has contention on a spinlock longer than 1 second.

2024-09-02perf test pmu: Set uninitialized PMU alias to nullVeronika Molnarova
Commit 3e0bf9fde2984469 ("perf pmu: Restore full PMU name wildcard support") adds a test case "PMU cmdline match" that covers PMU name wildcard support provided by function perf_pmu__match(). The test works with a wide range of supported combinations of PMU name matching but omits the case that if the perf_pmu__match() cannot match the PMU name to the wildcard, it tries to match its alias. However, this variable is not set up, causing the test case to fail when run with subprocesses or to segfault if run as a single process. ./perf test -vv 9 9: Sysfs PMU tests : 9.1: Parsing with PMU format directory : Ok 9.2: Parsing with PMU event : Ok 9.3: PMU event names : Ok 9.4: PMU name combining : Ok 9.5: PMU name comparison : Ok 9.6: PMU cmdline match : FAILED! ./perf test -F 9 9.1: Parsing with PMU format directory : Ok 9.2: Parsing with PMU event : Ok 9.3: PMU event names : Ok 9.4: PMU name combining : Ok 9.5: PMU name comparison : Ok Segmentation fault (core dumped) Initialize the PMU alias to null for all tests of perf_pmu__match() as this functionality is not being tested and the alias matching works exactly the same as the matching of the PMU name. ./perf test -F 9 9.1: Parsing with PMU format directory : Ok 9.2: Parsing with PMU event : Ok 9.3: PMU event names : Ok 9.4: PMU name combining : Ok 9.5: PMU name comparison : Ok 9.6: PMU cmdline match : Ok Fixes: 3e0bf9fde2984469 ("perf pmu: Restore full PMU name wildcard support") Signed-off-by: Veronika Molnarova <vmolnaro@redhat.com> Cc: james.clark@arm.com Cc: mpetlan@redhat.com Cc: rstoyano@redhat.com Link: https://lore.kernel.org/r/20240808103749.9356-1-vmolnaro@redhat.com Signed-off-by: Namhyung Kim <namhyung@kernel.org>
2024-09-01selftests: mm: fix build errors on armhfMuhammad Usama Anjum
The __NR_mmap isn't found on armhf. The mmap() is commonly available system call and its wrapper is present on all architectures. So it should be used directly. It solves problem for armhf and doesn't create problem for other architectures. Remove sys_mmap() functions as they aren't doing anything else other than calling mmap(). There is no need to set errno = 0 manually as glibc always resets it. For reference errors are as following: CC seal_elf seal_elf.c: In function 'sys_mmap': seal_elf.c:39:33: error: '__NR_mmap' undeclared (first use in this function) 39 | sret = (void *) syscall(__NR_mmap, addr, len, prot, | ^~~~~~~~~ mseal_test.c: In function 'sys_mmap': mseal_test.c:90:33: error: '__NR_mmap' undeclared (first use in this function) 90 | sret = (void *) syscall(__NR_mmap, addr, len, prot, | ^~~~~~~~~ Link: https://lkml.kernel.org/r/20240809082511.497266-1-usama.anjum@collabora.com Fixes: 4926c7a52de7 ("selftest mm/mseal memory sealing") Signed-off-by: Muhammad Usama Anjum <usama.anjum@collabora.com> Cc: Jeff Xu <jeffxu@chromium.org> Cc: Kees Cook <kees@kernel.org> Cc: Liam R.
