We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair.

Commit 9f4211bf ("HID: add mapping for camera access keys") added mapping for the camera access keys, but unfortunately used wrong usage codes for them. HUTRR72[1] specifies that camera access controls use 0x76, 0x077 and 0x78 usages in the consumer control page. Previously mapped 0xd5, 0xd6 and 0xd7 usages are actually defined in HUTRR64[2] as game recording controls.

Match alignment information in composite type declarations used by packed HOSTCMD report structures. Compiler packing attribute is not recursive for inner declarations. Mismatched alignment information can cause undefined behavior in code generated for accessing composite type members. struct pointers passed to thunderstrike_parse_board_info_payload and thunderstrike_parse_haptics_payload are an example of this being potentially problematic since alignment information from the packed HOSTCMD report is lost.

A previous patch addressed the fortified memcpy warning for most builds, but I still see this one with gcc-9: In file included from include/linux/string.h:254, from drivers/hid/hid-hyperv.c:8: In function 'fortify_memcpy_chk', inlined from 'mousevsc_on_receive' at drivers/hid/hid-hyperv.c:272:3: include/linux/fortify-string.h:583:4: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning] 583 | __write_overflow_field(p_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ My guess is that the WARN_ON() itself is what confuses gcc, so it no longer sees that there is a correct range check.

-
Suren Baghdasaryan authored
When forking a child process, the parent write-protects anonymous pages and COW-shares them with the child being forked using copy_present_pte(). We must not take any concurrent page faults on the source vma's as they are being processed, as we expect both the vma and the pte's behind it to be stable. For example, the anon_vma_fork() expects the parents vma->anon_vma to not change during the vma copy. A concurrent page fault on a page newly marked read-only by the page copy might trigger wp_page_copy() and a anon_vma_prepare(vma) on the source vma, defeating the anon_vma_clone() that wasn't done because the parent vma originally didn't have an anon_vma, but we now might end up copying a pte entry for a page that has one. Before the per-vma lock based changes, the mmap_lock guaranteed exclusion with concurrent page faults. But now we need to do a vma_start_write() to make sure no concurrent faults happen on this vma while it is being processed. This fix can potentially regress some fork-heavy workloads. Kernel build time did not show noticeable regression on a 56-core machine while a stress test mapping 10000 VMAs and forking 5000 times in a tight loop shows ~5% regression. If such fork time regression is unacceptable, disabling CONFIG_PER_VMA_LOCK should restore its performance. Further optimizations are possible if this regression proves to be problematic.

mmap_region adds a newly created VMA into VMA tree and might modify it afterwards before dropping the mmap_lock. This poses a problem for page faults handled under per-VMA locks because they don't take the mmap_lock and can stumble on this VMA while it's still being modified. Currently this does not pose a problem since post-addition modifications are done only for file-backed VMAs, which are not handled under per-VMA lock. However, once support for handling file-backed page faults with per-VMA locks is added, this will become a race. Fix this by write-locking the VMA before inserting it into the VMA tree. Other places where a new VMA is added into VMA tree do not modify it after the insertion, so do not need the same locking.

Build: - Allow generating vmlinux.h from BTF using `make GEN_VMLINUX_H=1` and skip if the vmlinux has no BTF. - Replace deprecated clang -target xxx option by --target=xxx. perf record: - Print event attributes with well known type and config symbols in the debug output like below: # perf record -e cycles,cpu-clock -C0 -vv true <SNIP> ------------------------------------------------------------ perf_event_attr: type 0 (PERF_TYPE_HARDWARE) size 136 config 0 (PERF_COUNT_HW_CPU_CYCLES) { sample_period, sample_freq } 4000 sample_type IP|TID|TIME|CPU|PERIOD|IDENTIFIER read_format ID disabled 1 inherit 1 freq 1 sample_id_all 1 exclude_guest 1 ------------------------------------------------------------ sys_perf_event_open: pid -1 cpu 0 group_fd -1 flags 0x8 = 5 ------------------------------------------------------------ perf_event_attr: type 1 (PERF_TYPE_SOFTWARE) size 136 config 0 (PERF_COUNT_SW_CPU_CLOCK) { sample_period, sample_freq } 4000 sample_type IP|TID|TIME|CPU|PERIOD|IDENTIFIER read_format ID disabled 1 inherit 1 freq 1 sample_id_all 1 exclude_guest 1 - Update AMD IBS event error message since it now support per-process profiling but no priviledge filters. $ sudo perf record -e ibs_op//k -C 0 Error: AMD IBS doesn't support privilege filtering. Try again without the privilege modifiers (like 'k') at the end. perf lock contention: - Support CSV style output using -x option $ sudo perf lock con -ab -x, sleep 1 # output: contended, total wait, max wait, avg wait, type, caller 19, 194232, 21415, 10222, spinlock, process_one_work+0x1f0 15, 162748, 23843, 10849, rwsem:R, do_user_addr_fault+0x40e 4, 86740, 23415, 21685, rwlock:R, ep_poll_callback+0x2d 1, 84281, 84281, 84281, mutex, iwl_mvm_async_handlers_wk+0x135 8, 67608, 27404, 8451, spinlock, __queue_work+0x174 3, 58616, 31125, 19538, rwsem:W, do_mprotect_pkey+0xff 3, 52953, 21172, 17651, rwlock:W, do_epoll_wait+0x248 2, 30324, 19704, 15162, rwsem:R, do_madvise+0x3ad 1, 24619, 24619, 24619, spinlock, rcu_core+0xd4 - Add --output option to save the data to a file not to be interfered by other debug messages. Test: - Fix event parsing test on ARM where there's no raw PMU nor supports PERF_PMU_CAP_EXTENDED_HW_TYPE. - Update the lock contention test case for CSV output. - Fix a segfault in the daemon command test. Vendor events (JSON): - Add has_event() to check if the given event is available on system at runtime. On Intel machines, some transaction events may not be present when TSC extensions are disabled. - Update Intel event metrics. Misc: - Sort symbols by name using an external array of pointers instead of a rbtree node in the symbol. This will save 16-bytes or 24-bytes per symbol whether the sorting is actually requested or not. - Fix unwinding DWARF callstacks using libdw when --symfs option is used" * tag 'perf-tools-for-v6.5-2-2023-07-06' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools-next: (38 commits) perf test: Fix event parsing test when PERF_PMU_CAP_EXTENDED_HW_TYPE isn't supported. perf test: Fix event parsing test on Arm perf evsel amd: Fix IBS error message perf: unwind: Fix symfs with libdw perf symbol: Fix uninitialized return value in symbols__find_by_name() perf test: Test perf lock contention CSV output perf lock contention: Add --output option perf lock contention: Add -x option for CSV style output perf lock: Remove stale comments perf vendor events intel: Update tigerlake to 1.13 perf vendor events intel: Update skylakex to 1.31 perf vendor events intel: Update skylake to 57 perf vendor events intel: Update sapphirerapids to 1.14 perf vendor events intel: Update icelakex to 1.21 perf vendor events intel: Update icelake to 1.19 perf vendor events intel: Update cascadelakex to 1.19 perf vendor events intel: Update meteorlake to 1.03 perf vendor events intel: Add rocketlake events/metrics perf vendor metrics intel: Make transaction metrics conditional perf jevents: Support for has_event function ...

Pull bitmap updates from Yury Norov: "Fixes for different bitmap pieces: - lib/test_bitmap: increment failure counter properly The tests that don't use expect_eq() macro to determine that a test is failured must increment failed_tests explicitly. - lib/bitmap: drop optimization of bitmap_{from,to}_arr64 bitmap_{from,to}_arr64() optimization is overly optimistic on 32-bit LE architectures when it's wired to bitmap_copy_clear_tail(). - nodemask: Drop duplicate check in for_each_node_mask() As the return value type of first_node() became unsigned, the node >= 0 became unnecessary. - cpumask: fix function description kernel-doc notation - MAINTAINERS: Add bits.h and bitfield.h to the BITMAP API record Add linux/bits.h and linux/bitfield.h for visibility" * tag 'bitmap-6.5-rc1' of https://github.com/norov/linux: MAINTAINERS: Add bitfield.h to the BITMAP API record MAINTAINERS: Add bits.h to the BITMAP API record cpumask: fix function description kernel-doc notation nodemask: Drop duplicate check in for_each_node_mask() lib/bitmap: drop optimization of bitmap_{from,to}_arr64 lib/test_bitmap: increment failure counter properly
