perf already support ignore_missing_thread for -p, but not yet applied to `perf stat -p <pid>`. This patch enables ignore_missing_thread for `perf stat -p <pid>`. Committer notes: And here is a refresher about the 'ignore_missing_thread' knob, from a previous patch using it: ca8000684ec4e66f ("perf evsel: Enable ignore_missing_thread for pid option") --- While monitoring a multithread process with pid option, perf sometimes may return sys_perf_event_open failure with 3(No such process) if any of the process's threads die before we open the event. However, we want perf continue monitoring the remaining threads and do not exit with error. --- Signed-off-by: Gang Li <ligang.bdlg@bytedance.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20220622030037.15005-1-ligang.bdlg@bytedance.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2022-06-26perf inject: Adjust output data offset for backward compatibilityRaul Silvera
When 'perf inject' creates a new file, it reuses the data offset from the input file. If there has been a change on the size of the header, as happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in a corrupted output file. This change adds the function perf_session__data_offset to compute the data offset based on the current header size, and uses that instead of the offset from the original input file.

2022-06-26perf build-id: Fix caching files with a wrong build IDAdrian Hunter
Build ID events associate a file name with a build ID. However, when using perf inject, there is no guarantee that the file on the current machine at the current time has that build ID. Fix by comparing the build IDs and skip adding to the cache if they are different. Example: $ echo "int main() {return 0;}" > prog.c $ gcc -o prog prog.c $ perf record --buildid-all ./prog [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.019 MB perf.data ] $ file-buildid() { file $1 | awk -F= '{print $2}' | awk -F, '{print $1}' ; } $ file-buildid prog 444ad9be165d8058a48ce2ffb4e9f55854a3293e $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf 444ad9be165d8058a48ce2ffb4e9f55854a3293e $ echo "int main() {return 1;}" > prog.c $ gcc -o prog prog.c $ file-buildid prog 885524d5aaa24008a3e2b06caa3ea95d013c0fc5 Before: $ perf buildid-cache --purge $(pwd)/prog $ perf inject -i perf.data -o junk $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf 885524d5aaa24008a3e2b06caa3ea95d013c0fc5 $ After: $ perf buildid-cache --purge $(pwd)/prog $ perf inject -i perf.data -o junk $ file-buildid ~/.debug/$(pwd)/prog/444ad9be165d8058a48ce2ffb4e9f55854a3293e/elf $ Fixes: 454c407ec17a0c63 ("perf: add perf-inject builtin") Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Tom Zanussi <tzanussi@gmail.com> Link: https://lore.kernel.org/r/20220621125144.5623-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2022-06-26parisc: Fix flush_anon_page on PA8800/PA8900John David Anglin
Anonymous pages are allocated with the shared mappings colouring, SHM_COLOUR. Since the alias boundary on machines with PA8800 and PA8900 processors is unknown, flush_user_cache_page() might not flush all mappings of a shared anonymous page. Flushing the whole data cache flushes all mappings. This won't fix all coherency issues with shared mappings but it seems to work well in practice. I haven't seen any random memory faults in almost a month on a rp3440 running as a debian buildd machine. There is a small preformance hit.

2022-06-26kbuild: link vmlinux only once for CONFIG_TRIM_UNUSED_KSYMS (2nd attempt)Masahiro Yamada
If CONFIG_TRIM_UNUSED_KSYMS is enabled and the kernel is built from a pristine state, the vmlinux is linked twice. Commit 3fdc7d3fe4c0 ("kbuild: link vmlinux only once for CONFIG_TRIM_UNUSED_KSYMS") explains why this happens, but it did not fix the issue at all. Now I realized I had applied a wrong patch. In v1 patch [1], the autoksyms_recursive target correctly recurses to "$(MAKE) -f $(srctree)/Makefile autoksyms_recursive". In v2 patch [2], I accidentally dropped the diff line, and it recurses to "$(MAKE) -f $(srctree)/Makefile vmlinux". Restore the code I intended in v1.

2022-06-24net: dp83822: disable rx error interruptEnguerrand de Ribaucourt
Some RX errors, notably when disconnecting the cable, increase the RCSR register. Once half full (0x7fff), an interrupt flood is generated. I measured ~3k/s interrupts even after the RX errors transfer was stopped. Since we don't read and clear the RCSR register, we should disable this interrupt.

2022-06-24net: dp83822: disable false carrier interruptEnguerrand de Ribaucourt
When unplugging an Ethernet cable, false carrier events were produced by the PHY at a very high rate. Once the false carrier counter full, an interrupt was triggered every few clock cycles until the cable was replugged. This resulted in approximately 10k/s interrupts. Since the false carrier counter (FCSCR) is never used, we can safely disable this interrupt. In addition to improving performance, this also solved MDIO read timeouts I was randomly encountering with an i.MX8 fec MAC because of the interrupt flood. The interrupt count and MDIO timeout fix were tested on a v5.4.110 kernel.

2022-06-24tcp: add a missing nf_reset_ct() in 3WHS handlingEric Dumazet
When the third packet of 3WHS connection establishment contains payload, it is added into socket receive queue without the XFRM check and the drop of connection tracking context. This means that if the data is left unread in the socket receive queue, conntrack module can not be unloaded. As most applications usually reads the incoming data immediately after accept(), bug has been hiding for quite a long time. Commit 68822bdf76f1 ("net: generalize skb freeing deferral to per-cpu lists") exposed this bug because even if the application reads this data, the skb with nfct state could stay in a per-cpu cache for an arbitrary time, if said cpu no longer process RX softirqs. Many thanks to Ilya Maximets for reporting this issue, and for testing various patches: https://lore.kernel.org/netdev/20220619003919.394622-1-i.maximets@ovn.org/ Note that I also added a missing xfrm4_policy_check() call, although this is probably not a big issue, as the SYN packet should have been dropped earlier.
