2022-09-21perf stat: Use evsel->core.cpus to iterate cpus in BPF cgroup countersNamhyung Kim
If it mixes core and uncore events, each evsel would have different cpu map. But it assumed they are same with evlist's all_cpus and accessed by the same index. This resulted in a crash like below. $ perf stat -a --bpf-counters --for-each_cgroup ^. -e cycles,imc/cas_count_read/ sleep 1 Segmentation fault While it's not recommended to use uncore events for cgroup aggregation, it should not crash.

2022-09-21perf stat: Fix BPF program section nameNamhyung Kim
It seems the recent libbpf got more strict about the section name. I'm seeing a failure like this: $ sudo ./perf stat -a --bpf-counters --for-each-cgroup ^. sleep 1 libbpf: prog 'on_cgrp_switch': missing BPF prog type, check ELF section name 'perf_events' libbpf: prog 'on_cgrp_switch': failed to load: -22 libbpf: failed to load object 'bperf_cgroup_bpf' libbpf: failed to load BPF skeleton 'bperf_cgroup_bpf': -22 Failed to load cgroup skeleton The section name should be 'perf_event' (without the trailing 's'). Although it's related to the libbpf change, it'd be better fix the section name in the first place.

2022-09-20selftests: seg6: add selftest for NEXT-C-SID flavor in SRv6 End behaviorAndrea Mayer
This selftest is designed for testing the support of NEXT-C-SID flavor for SRv6 End behavior. It instantiates a virtual network composed of several nodes: hosts and SRv6 routers. Each node is realized using a network namespace that is properly interconnected to others through veth pairs. The test considers SRv6 routers implementing IPv4/IPv6 L3 VPNs leveraged by hosts for communicating with each other. Such routers i) apply different SRv6 Policies to the traffic received from connected hosts, considering the IPv4 or IPv6 protocols; ii) use the NEXT-C-SID compression mechanism for encoding several SRv6 segments within a single 128-bit SID address, referred to as a Compressed SID (C-SID) container. The NEXT-C-SID is provided as a "flavor" of the SRv6 End behavior, enabling it to properly process the C-SID containers. The correct execution of the enabled NEXT-C-SID SRv6 End behavior is verified through reachability tests carried out between hosts belonging to the same VPN.

2022-09-19selftests: mlxsw: Add QOS test for maximum use of descriptorsAmit Cohen
Add an equivalent test to qos_burst, the test's purpose is same, but the new test uses simpler topology and does not require forcing low speed. In addition, it can be run Spectrum-2 and not only Spectrum-3+. The idea is to use a shaper in order to limit the traffic and create congestion. qos_burst test uses small pool, sends many small packets, and verify that packets are not dropped, which means that many descriptors can be handled. This test should check the change that commit c864769add96 ("mlxsw: Configure descriptor buffers") pushed. Instead, the new test tries to use more than 85% of maximum supported descriptors. The idea is to use big pool (as much as the ASIC supports), such that the pool size does not limit the traffic, then send many small packets, which means that many descriptors are used, and check how many packets the switch can handle. The usage of shaper allows to run the test in all ASICs, regardless of the CPU abilities, as it is able to create the congestion with low rate of packets.

2022-09-19selftests: mlxsw: Use shapers in QOS RED tests instead of forcing speedAmit Cohen
QOS tests create congestion and verify the switch behavior. To create congestion, they need to have more traffic than the port can handle, so some of them force 1Gbps speed. The tests assume that 1Gbps speed is supported, otherwise, they will fail. Spectrum-4 ASIC will not support this speed in all ports, so to be able to run the tests there, some adjustments are required. Use shapers to limit the traffic instead of forcing speed. Note that for several ports, the speed configuration is just for autoneg issues, so shaper is not needed instead. The tests already use ETS qdisc as a root and RED qdiscs as children. Add a new TBF shaper to limit the rate of traffic, and use it as a root qdisc, then save the previous hierarchy of qdiscs under the new TBF root. In some ASICs, the shapers do not limit the traffic as accurately as forcing speed. To make the tests stable, allow the backlog size to be up to +-10% of the threshold. The aim of the tests is to make sure that with backlog << threshold, there are no drops, and that packets are dropped somewhere in vicinity of the configured threshold.

2022-09-08perf record: Fix synthesis failure warningsAdrian Hunter
Some calls to synthesis functions set err < 0 but only warn about the failure and continue. However they do not set err back to zero, relying on subsequent code to do that. That changed with the introduction of option --synth. When --synth=no subsequent functions that set err back to zero are not called. Fix by setting err = 0 in those cases. Example: Before: $ perf record --no-bpf-event --synth=all -o /tmp/huh uname Couldn't synthesize bpf events. Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.014 MB /tmp/huh (7 samples) ] $ perf record --no-bpf-event --synth=no -o /tmp/huh uname Couldn't synthesize bpf events. After: $ perf record --no-bpf-event --synth=no -o /tmp/huh uname Couldn't synthesize bpf events.

2022-09-08perf script: Fix Cannot print 'iregs' field for hybrid systemsZhengjun Xing
Commit b91e5492f9d7ca89 ("perf record: Add a dummy event on hybrid systems to collect metadata records") adds a dummy event on hybrid systems to fix the symbol "unknown" issue when the workload is created in a P-core but runs on an E-core. The added dummy event will cause "perf script -F iregs" to fail. Dummy events do not have "iregs" attribute set, so when we do evsel__check_attr, the "iregs" attribute check will fail, so the issue happened. The following commit [1] has fixed a similar issue by skipping the attr check for the dummy event because it does not have any samples anyway. It works okay for the normal mode, but the issue still happened when running the test in the pipe mode. In the pipe mode, it calls process_attr() which still checks the attr for the dummy event. This commit fixed the issue by skipping the attr check for the dummy event in the API evsel__check_attr, Otherwise, we have to patch everywhere when evsel__check_attr() is called.

2022-09-08libperf evlist: Fix per-thread mmaps for multi-threaded targetsAdrian Hunter
The offending commit removed mmap_per_thread(), which did not consider the different set-output rules for per-thread mmaps i.e. in the per-thread case set-output is used for file descriptors of the same thread not the same cpu. This was not immediately noticed because it only happens with multi-threaded targets and we do not have a test for that yet. Reinstate mmap_per_thread() expanding it to cover also system-wide per-cpu events i.e. to continue to allow the mixing of per-thread and per-cpu mmaps. Debug messages (with -vv) show the file descriptors that are opened with sys_perf_event_open. New debug messages are added (needs -vvv) that show also which file descriptors are mmapped and which are redirected with set-output. In the per-cpu case (cpu != -1) file descriptors for the same CPU are set-output to the first file descriptor for that CPU. In the per-thread case (cpu == -1) file descriptors for the same thread are set-output to the first file descriptor for that thread. Example (process 17489 has 2 threads): Before (but with new debug prints): $ perf record --no-bpf-event -vvv --per-thread -p 17489 <SNIP> sys_perf_event_open: pid 17489 cpu -1 group_fd -1 flags 0x8 = 5 sys_perf_event_open: pid 17490 cpu -1 group_fd -1 flags 0x8 = 6 <SNIP> libperf: idx 0: mmapping fd 5 libperf: idx 0: set output fd 6 -> 5 failed to mmap with 22 (Invalid argument) After: $ perf record --no-bpf-event -vvv --per-thread -p 17489 <SNIP> sys_perf_event_open: pid 17489 cpu -1 group_fd -1 flags 0x8 = 5 sys_perf_event_open: pid 17490 cpu -1 group_fd -1 flags 0x8 = 6 <SNIP> libperf: mmap_per_thread: nr cpu values (may include -1) 1 nr threads 2 libperf: idx 0: mmapping fd 5 libperf: idx 1: mmapping fd 6 <SNIP> [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.018 MB perf.data (15 samples) ] Per-cpu example (process 20341 has 2 threads, same as above): $ perf record --no-bpf-event -vvv -p 20341 <SNIP> sys_perf_event_open: pid 20341 cpu 0 group_fd -1 flags 0x8 = 5 sys_perf_event_open: pid 20342 cpu 0 group_fd -1 flags 0x8 = 6 sys_perf_event_open: pid 20341 cpu 1 group_fd -1 flags 0x8 = 7 sys_perf_event_open: pid 20342 cpu 1 group_fd -1 flags 0x8 = 8 sys_perf_event_open: pid 20341 cpu 2 group_fd -1 flags 0x8 = 9 sys_perf_event_open: pid 20342 cpu 2 group_fd -1 flags 0x8 = 10 sys_perf_event_open: pid 20341 cpu 3 group_fd -1 flags 0x8 = 11 sys_perf_event_open: pid 20342 cpu 3 group_fd -1 flags 0x8 = 12 sys_perf_event_open: pid 20341 cpu 4 group_fd -1 flags 0x8 = 13 sys_perf_event_open: pid 20342 cpu 4 group_fd -1 flags 0x8 = 14 sys_perf_event_open: pid 20341 cpu 5 group_fd -1 flags 0x8 = 15 sys_perf_event_open: pid 20342 cpu 5 group_fd -1 flags 0x8 = 16 sys_perf_event_open: pid 20341 cpu 6 group_fd -1 flags 0x8 = 17 sys_perf_event_open: pid 20342 cpu 6 group_fd -1 flags 0x8 = 18 sys_perf_event_open: pid 20341 cpu 7 group_fd -1 flags 0x8 = 19 sys_perf_event_open: pid 20342 cpu 7 group_fd -1 flags 0x8 = 20 <SNIP> libperf: mmap_per_cpu: nr cpu values 8 nr threads 2 libperf: idx 0: mmapping fd 5 libperf: idx 0: set output fd 6 -> 5 libperf: idx 1: mmapping fd 7 libperf: idx 1: set output fd 8 -> 7 libperf: idx 2: mmapping fd 9 libperf: idx 2: set output fd 10 -> 9 libperf: idx 3: mmapping fd 11 libperf: idx 3: set output fd 12 -> 11 libperf: idx 4: mmapping fd 13 libperf: idx 4: set output fd 14 -> 13 libperf: idx 5: mmapping fd 15 libperf: idx 5: set output fd 16 -> 15 libperf: idx 6: mmapping fd 17 libperf: idx 6: set output fd 18 -> 17 libperf: idx 7: mmapping fd 19 libperf: idx 7: set output fd 20 -> 19 <SNIP> [ perf record: Woken up 7 times to write data ] [ perf record: Captured and wrote 0.020 MB perf.data (17 samples) ] Fixes: ae4f8ae16a078964 ("libperf evlist: Allow mixing per-thread and per-cpu mmaps") Reported-by: Tomáš Trnka <trnka@scm.com> Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=216441 Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20220905114209.8389-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

In other words, allow for partial replacement, from Shmulik Ladkani. 4) Add a new cgroup iterator to BPF with different traversal options, from Hao Luo. 5) Support for BPF to collect hierarchical cgroup statistics efficiently through BPF integration with the rstat framework, from Yosry Ahmed. 6) Support bpf_{g,s}et_retval() under more BPF cgroup hooks, from Stanislav Fomichev. 7) BPF hash table and local storages fixes under fully preemptible kernel, from Hou Tao. 8) Add various improvements to BPF selftests and libbpf for compilation with gcc BPF backend, from James Hilliard. 9) Fix verifier helper permissions and reference state management for synchronous callbacks, from Kumar Kartikeya Dwivedi. 10) Add support for BPF selftest's xskxceiver to also be used against real devices that support MAC loopback, from Maciej Fijalkowski. 11) Various fixes to the bpf-helpers(7) man page generation script, from Quentin Monnet. 12) Document BPF verifier's tnum_in(tnum_range(), ...) gotchas, from Shung-Hsi Yu. 13) Various minor misc improvements all over the place. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (106 commits) bpf: Optimize rcu_barrier usage between hash map and bpf_mem_alloc. bpf: Remove usage of kmem_cache from bpf_mem_cache. bpf: Remove prealloc-only restriction for sleepable bpf programs. bpf: Prepare bpf_mem_alloc to be used by sleepable bpf programs. bpf: Remove tracing program restriction on map types bpf: Convert percpu hash map to per-cpu bpf_mem_alloc. bpf: Add percpu allocation support to bpf_mem_alloc. bpf: Batch call_rcu callbacks instead of SLAB_TYPESAFE_BY_RCU. bpf: Adjust low/high watermarks in bpf_mem_cache bpf: Optimize call_rcu in non-preallocated hash map. bpf: Optimize element count in non-preallocated hash map. bpf: Relax the requirement to use preallocated hash maps in tracing progs. samples/bpf: Reduce syscall overhead in map_perf_test. selftests/bpf: Improve test coverage of test_maps bpf: Convert hash map to bpf_mem_alloc. bpf: Introduce any context BPF specific memory allocator. selftest/bpf: Add test for bpf_getsockopt() bpf: Change bpf_getsockopt(SOL_IPV6) to reuse do_ipv6_getsockopt() bpf: Change bpf_getsockopt(SOL_IP) to reuse do_ip_getsockopt() bpf: Change bpf_getsockopt(SOL_TCP) to reuse do_tcp_getsockopt() ... ==================== Link: https://lore.kernel.org/r/20220905161136.9150-1-daniel@iogearbox.net Signed-off-by: Paolo Abeni <pabeni@redhat.com>
