2022-12-22afs: Fix lost servers_outstanding countDavid Howells1-1/+4
The afs_fs_probe_dispatcher() work function is passed a count on net->servers_outstanding when it is scheduled (which may come via its timer). This is passed back to the work_item, passed to the timer or dropped at the end of the dispatcher function. But, at the top of the dispatcher function, there are two checks which skip the rest of the function: if the network namespace is being destroyed or if there are no fileservers to probe. These two return paths, however, do not drop the count passed to the dispatcher, and so, sometimes, the destruction of a network namespace, such as induced by rmmod of the kafs module, may get stuck in afs_purge_servers(), waiting for net->servers_outstanding to become zero. Fix this by adding the missing decrements in afs_fs_probe_dispatcher().

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull parisc updates from Helge Deller: "There is one noteable patch, which allows the parisc kernel to use the same MADV_xxx constants as the other architectures going forward. With that change only alpha has one entry left (MADV_DONTNEED is 6 vs 4 on others) which is different. To prevent an ABI breakage, a wrapper is included which translates old MADV values to the new ones, so existing userspace isn't affected. Reason for that patch is, that some applications wrongly used the standard MADV_xxx values even on some non-x86 platforms and as such those programs failed to run correctly on parisc (examples are qemu-user, tor browser and boringssl). Then the kgdb console and the LED code received some fixes, and some 0-day warnings are now gone. Finally, the very last compile warning which was visible during a kernel build is now fixed too (in the vDSO code). The majority of the patches are tagged for stable series and in summary this patchset is quite small and drops more code than it adds: Fixes: - Fix potential null-ptr-deref in start_task() - Fix kgdb console on serial port - Add missing FORCE prerequisites in Makefile - Drop PMD_SHIFT from calculation in pgtable.h Enhancements: - Implement a wrapper to align madvise() MADV_* constants with other architectures - If machine supports running MPE/XL, show the MPE model string Cleanups: - Drop duplicate kgdb console code - Indenting fixes in setup_cmdline()" * tag 'parisc-for-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Show MPE/iX model string at bootup parisc: Add missing FORCE prerequisites in Makefile parisc: Move pdc_result struct to firmware.c parisc: Drop locking in pdc console code parisc: Drop duplicate kgdb_pdc console parisc: Fix locking in pdc_iodc_print() firmware call parisc: Drop PMD_SHIFT from calculation in pgtable.h parisc: Align parisc MADV_XXX constants with all other architectures parisc: led: Fix potential null-ptr-deref in start_task() parisc: Fix inconsistent indenting in setup_cmdline()

Adjust some MADV_XXX constants to be in sync what their values are on all other platforms. There is currently no reason to have an own numbering on parisc, but it requires workarounds in many userspace sources (e.g. glibc, qemu, ...) - which are often forgotten and thus introduce bugs and different behaviour on parisc. A wrapper avoids an ABI breakage for existing userspace applications by translating any old values to the new ones, so this change allows us to move over all programs to the new ABI over time.

2022-12-17powerpc/msi: Fix deassociation of MSI descriptorsMarc Zyngier5-0/+5
Since 2f2940d16823 ("genirq/msi: Remove filter from msi_free_descs_free_range()"), the core MSI code relies on the msi_desc->irq field to have been cleared before the descriptor can be freed, as it indicates that there is no association with a device anymore. The irq domain code provides this guarantee, and so does s390, which is one of the two architectures not using irq domains for MSIs. Powerpc, however, is missing this particular requirements, leading in a splat and leaked MSI descriptors. Adding the now required irq reset to the handful of powerpc backends that implement MSIs fixes that particular problem.

The previous build fix left a remaining issue in configurations with 64-bit dma_addr_t on 32-bit architectures: drivers/infiniband/sw/siw/siw_qp_tx.c: In function 'siw_get_pblpage': drivers/infiniband/sw/siw/siw_qp_tx.c:32:37: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 32 | return virt_to_page((void *)paddr); | ^ Use the same double cast here that the driver uses elsewhere to convert between dma_addr_t and void*.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull perf tools updates from Arnaldo Carvalho de Melo: "Libraries: - Drop the old copy of libtraceevent in tools/lib/traceevent/ now that all major distros ship it from its external repository. This is now just another feature detection, emitting a warning when the libtraceevent-dev[el] package isn't installed, disabling the build of perf features and tools that strictly require parsing things from tracefs while keeping the core functionality present and working with a subset of the events, the most used ones like CPU cycles, hardware cache and also vendor events, etc. This was tested with lots of containers for Fedora, Debian, OpenSUSE, Alpine Linux, Ubuntu, with cross builds, etc. Build: - Update to C standard to gnu11, like was done for the kernel. - Install the tools/lib/ libraries locally instead of having headers searched directly from the source code directories, to help the cases where we can build either from in-kernel source libraries or from the same library shipped as a distro package, as is the case with libbpf and was the case with libtraceevent. perf stat: - Do not delay the workload with --delay, the delay is just for starting to count the events, to skip noise at workload startup. - When we have events for each cgroup, the metric should be printed for each cgroup separately. $ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1 Performance counter stats for 'system wide': GHz insn per cycle branch-misses of all branches system.slice 3.792 0.61 3.24% user.slice 3.661 2.32 0.37% - Fix printing field separator in CSV metrics output. - Fix --metric-only --json output. - Fix summary output in CSV with --metric-only. - Update event group check for support of uncore event. perf test: - Stop requiring a C toolchain in shell tests, instead add a workload option that has all the previously C snippets built as part of 'perf test -w' that then get used in the 'perf test' shell scripts. - Add event group test for events in multiple PMUs - The "kernel lock contention analysis" test should not print warnings in quiet mode. - Add attr tests for ARM64's new VG register. - Fix record test on KVM guests, as using precise flag with the br_inst_retired.near_call event causes the test fail on KVM guests, even when the guests have PMU forwarding enabled and the event itself is supported, so just remove the precise flag from the event. - Add mechanism for skipping attr tests on specific kernel versions where it is known that these checks will fail. - Skip watchpoint tests if no watchpoints available. - Add more Intel PT 'perf test' entries: hybrid CPUs, split the packet decoder into a suite of subtests. perf script: - Introduce task analyzer python script, where one first records some events: Recording can be done in two ways: $ perf script record tasks-analyzer -- sleep 10 $ perf record -e sched:sched_switch -a -- sleep 10 The script can parse any perf.data files, as long as it has sched:sched_switch events, other events will be ignored. The most simple report use case is to just call the script without arguments. Runtime is the time the task was running on the CPU, Time Out-In is the time between the process being scheduled *out* and scheduled back *in*. So the last time span between two executions: $ perf script report tasks-analyzer Switched-In Switched-Out CPU PID TID Comm Runtime Time Out-In 15576.658891407 15576.659156086 4 2412 2428 gdbus 265 1949 15576.659111320 15576.659455410 0 2412 2412 gnome-shell 344 2267 15576.659491326 15576.659506173 2 74 74 kworker/2:1 15 13145 15576.659506173 15576.659825748 2 2858 2858 gnome-terminal- 320 63263 15576.659871270 15576.659902872 6 20932 20932 kworker/u16:0 32 2314582 15576.659909951 15576.659945501 3 27264 27264 sh 36 -1 15576.659853285 15576.659971052 7 27265 27265 perf 118 5050741 [...] perf lock: - Allow concurrent record and report to support live monitoring of kernel lock contention without BPF: # perf lock record -a -o- sleep 1 | perf lock contention -i- contended total wait max wait avg wait type caller 2 10.27 us 6.17 us 5.13 us spinlock load_balance+0xc03 1 5.29 us 5.29 us 5.29 us rwlock:W ep_scan_ready_list+0x54 1 4.12 us 4.12 us 4.12 us spinlock smpboot_thread_fn+0x116 1 3.28 us 3.28 us 3.28 us mutex pipe_read+0x50 - Implement -t/--threads option when using BPF: $ sudo ./perf lock contention -abt -E 5 sleep 1 contended total wait max wait avg wait pid comm 1 740.66 ms 740.66 ms 740.66 ms 1950 nv_queue 3 305.50 ms 298.19 ms 101.83 ms 1884 nvidia-modeset/ 1 25.14 us 25.14 us 25.14 us 2725038 EventManager_De 12 23.09 us 9.30 us 1.92 us 0 swapper 1 20.18 us 20.18 us 20.18 us 2725033 EventManager_De - Add -l/--lock-addr to aggregate per-lock-instance contention: $ sudo ./perf lock contention -abl sleep 1 contended total wait max wait avg wait address symbol 1 36.28 us 36.28 us 36.28 us ffff92615d6448b8 9 10.91 us 1.84 us 1.21 us ffffffffbaed50c0 rcu_state 1 10.49 us 10.49 us 10.49 us ffff9262ac4f0c80 8 4.68 us 1.67 us 585 ns ffffffffbae07a40 jiffies_lock 3 3.03 us 1.45 us 1.01 us ffff9262277861e0 1 924 ns 924 ns 924 ns ffff926095ba9d20 1 436 ns 436 ns 436 ns ffff9260bfda4f60 perf record: - Add remaining branch filters: "no_cycles", "no_flags" & "hw_index", to be used with hardware such as Intel's LBR that allows things like stitching stacks of two samples to overcome the limits of the number of LBR registers. Symbol resolution: - Handle .debug files created with 'objcopy --only-keep-debug', where program headers are zeroed and thus can't be used for adjustments, use the info in the runtime_ss (runtime ELF) instead. perf trace: - Add BPF based augmenter for the 'perf_event_open's 'struct perf_event_attr' argument. - Add BPF based augmenter for the 'clock_gettime's 'struct timespec' argument. - In both cases the syscall tracepoint has just the pointer value, we need to hook a BPF program to collect the pointer contents, and then, in userspace, pretty print it in 'perf trace'. perf list: - Introduce JSON output of events. - Streamline how the expression specifying what events should be shown is handled, fixing several corner cases, such as the metric filter that is specified as a glob but was using strstr(). perf probe: - Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang generating DWARF5 like that. - Use dwarf_attr_integrate() as generic DWARF attr accessor as it supersedes dwarf_attr(), supporting abstact origin DIEs. perf inject: - Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID so that perf.data readers can get the real build-id size and avoid trailing zeroes. perf data: - Add tracepoint fields when converting a perf.data file to JSON. arm64: - Fix mksyscalltbl, don't lose syscalls due to sort -nu. - Add Arm Neoverse V2 PMU events. riscv: - Add riscv sbi firmware std event files. - Add Sifive U74 vendor events (JSON) file. - Add some more events and metrics for Alderlake/Alderlake-N. Documentation: - Add data documentation for the PMU structs in the C source code. Miscellaneous: - Periodic sanitization of headers, adding missing includes, removing needless ones, creating new ones, etc. - Use sig_atomic_t for signal handlers to avoid undefined behaviour in all perf tools. - Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF examples. - Remove some old perf bpf examples, leave the best ones that demonstrate how to associate BPF functions to points in the kernel. - Make quiet mode consistent between tools. - Use dedicated non-atomic clear/set bit helpers. - Use "grep -E" instead of "egrep" as recommended by warning emitted by GNU grep since at least version 3.8. - Complete list of supported subcommands in the 'perf daemon' help message. - Update John Garry's email address for arm64 perf tooling on the MAINTAINERS file, he moved from Huawei to Oracle" * tag 'perf-tools-for-v6.2-1-2022-12-16' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (239 commits) libperf: Fix install_pkgconfig target perf tools: Use "grep -E" instead of "egrep" perf stat: Do not delay the workload with --delay perf evlist: Remove group option. perf build: Fix python/perf.so library's name perf test arm64: Add attr tests for new VG register perf test: Add mechanism for skipping attr tests on kernel versions perf test: Add mechanism for skipping attr tests on auxiliary vector values perf test: Add ability to test exit code for attr tests perf test: add new task-analyzer tests perf script: task-analyzer add csv support perf script: Introduce task analyzer python script perf cs-etm: Print auxtrace info even if OpenCSD isn't linked perf cs-etm: Cleanup cs_etm__process_auxtrace_info() perf cs-etm: Tidy up auxtrace info header printing perf cs-etm: Remove unused stub methods perf cs-etm: Print unknown header version as an error perf test: Update perf lock contention test perf lock contention: Add -l/--lock-addr option perf lock contention: Implement -t/--threads option for BPF ...
