Pablo Neira Ayuso says: ==================== Netfilter fixes for net 1) Use kfree_rcu(ptr, rcu) variant, using kfree_rcu(ptr) was not intentional. From Eric Dumazet. 2) Use-after-free in netfilter hook core, from Eric Dumazet. 3) Missing rcu read lock side for netfilter egress hook, from Florian Westphal. 4) nf_queue assume state->sk is full socket while it might not be. Invoke sock_gen_put(), from Florian Westphal. 5) Add selftest to exercise the reported KASAN splat in 4) 6) Fix possible use-after-free in nf_queue in case sk_refcnt is 0. Also from Florian. 7) Use input interface index only for hardware offload, not for the software plane. This breaks tc ct action.

2022-02-21tools/cgroup/slabinfo: update to work with struct slabRoman Gushchin1-15/+15
After the introduction of the dedicated struct slab to describe slab pages by commit d122019bf061 ("mm: Split slab into its own type") and the following removal of the corresponding struct page's fields by commit 07f910f9b729 ("mm: Remove slab from struct page") the memcg_slabinfo tool broke. An attempt to run it produces a trace like this: Traceback (most recent call last): File "/usr/bin/drgn", line 33, in <module> sys.exit(load_entry_point('drgn==0.0.16', 'console_scripts', 'drgn')()) File "/usr/lib64/python3.9/site-packages/drgn/internal/cli.py", line 133, in main runpy.run_path(args.script[0], init_globals=init_globals, run_name="__main__") File "/usr/lib64/python3.9/runpy.py", line 268, in run_path return _run_module_code(code, init_globals, run_name, File "/usr/lib64/python3.9/runpy.py", line 97, in _run_module_code _run_code(code, mod_globals, init_globals, File "/usr/lib64/python3.9/runpy.py", line 87, in _run_code exec(code, run_globals) File "memcg_slabinfo.py", line 226, in <module> main() File "memcg_slabinfo.py", line 199, in main cache = page.slab_cache AttributeError: 'struct page' has no member 'slab_cache' The problem can be fixed by explicitly casting struct page * to struct slab * for slab pages.

2022-02-19selftests: mptcp: be more conservative with cookie MPJ limitsPaolo Abeni1-3/+12
Since commit 2843ff6f36db ("mptcp: remote addresses fullmesh"), an MPTCP client can attempt creating multiple MPJ subflow simultaneusly. In such scenario the server, when syncookies are enabled, could end-up accepting incoming MPJ syn even above the configured subflow limit, as the such limit can be enforced in a reliable way only after the subflow creation. In case of syncookie, only after the 3rd ack reception. As a consequence the related self-tests case sporadically fails, as it verify that the server always accept the expected number of MPJ syn. Address the issues relaxing the MPJ syn number constrain. Note that the check on the accepted number of MPJ 3rd ack still remains intact.

Tzvetomir Stoyanov reported an issue with using macro perf_cpu_map__for_each_cpu using private perf_cpu object. The issue is caused by recent change that wrapped cpu in struct perf_cpu to distinguish it from cpu indexes. We need to make struct perf_cpu public. Add a simple test for using the perf_cpu_map__for_each_cpu macro.

2022-02-16perf cs-etm: Fix corrupt inject files when only last branch option is enabledJames Clark1-0/+2
'perf inject' with Coresight data generates files that cannot be opened when only the last branch option is specified: perf inject -i perf.data --itrace=l -o inject.data perf script -i inject.data 0x33faa8 [0x8]: failed to process type: 9 [Bad address] This is because cs_etm__synth_instruction_sample() is called even when the sample type for instructions hasn't been setup. Last branch records are attached to instruction samples so it doesn't make sense to generate them when --itrace=i isn't specified anyway. This change disables all calls of cs_etm__synth_instruction_sample() unless --itrace=i is specified, resulting in a file with no samples if only --itrace=l is provided, rather than a bad file.

2022-02-16perf trace: Avoid early exit due SIGCHLD from non-workload processesChangbin Du1-5/+18
The function trace__symbols_init() runs "perf-read-vdso32" and that ends up with a SIGCHLD delivered to 'perf'. And this SIGCHLD make perf exit early. 'perf trace' should exit only if the SIGCHLD is from our workload process. So let's use sigaction() instead of signal() to match such condition. Committer notes: Use memset to zero the 'struct sigaction' variable as the '= { 0 }' method isn't accepted in many compiler versions, e.g.: 4 34.02 alpine:3.6 : FAIL clang version 4.0.0 (tags/RELEASE_400/final) builtin-trace.c:4897:35: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces] struct sigaction sigchld_act = { 0 }; ^ {} builtin-trace.c:4897:37: error: missing field 'sa_mask' initializer [-Werror,-Wmissing-field-initializers] struct sigaction sigchld_act = { 0 }; ^ 2 errors generated. 6 32.60 alpine:3.8 : FAIL gcc version 6.4.0 (Alpine 6.4.0) builtin-trace.c:4897:35: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces] struct sigaction sigchld_act = { 0 }; ^ {} builtin-trace.c:4897:37: error: missing field 'sa_mask' initializer [-Werror,-Wmissing-field-initializers] struct sigaction sigchld_act = { 0 }; ^ 2 errors generated. 7 34.82 alpine:3.9 : FAIL gcc version 8.3.0 (Alpine 8.3.0) builtin-trace.c:4897:35: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces] struct sigaction sigchld_act = { 0 }; ^ {} builtin-trace.c:4897:37: error: missing field 'sa_mask' initializer [-Werror,-Wmissing-field-initializers] struct sigaction sigchld_act = { 0 }; ^ 2 errors generated.

Because old kernel headers don't have definition of macro __NR_clone3 which is required for these two tests. Since under selftests/, we can install headers once for all tests (the default INSTALL_HDR_PATH is usr/include), fix it by adding usr/include to the list of directories to be searched.

2022-02-08rtla: Fix segmentation fault when failing to enable -tDaniel Bristot de Oliveira5-16/+15
rtla osnoise and timerlat are causing a segmentation fault when running with the --trace option on a kernel that does not support multiple instances. For example: [root@f34 rtla]# rtla osnoise top -t failed to enable the tracer osnoise Could not enable osnoiser tracer for tracing Failed to enable the trace instance Segmentation fault (core dumped) This error happens because the exit code of the tools is trying to destroy the trace instance that failed to be created. Make osnoise_destroy_tool() aware of possible NULL osnoise_tool *, and do not attempt to destroy it. This also simplifies the exit code.

2022-02-06perf stat: Fix display of grouped aliased eventsIan Rogers1-9/+10
An event may have a number of uncore aliases that when added to the evlist are consecutive. If there are multiple uncore events in a group then parse_events__set_leader_for_uncore_aliase will reorder the evlist so that events on the same PMU are adjacent. The collect_all_aliases function assumes that aliases are in blocks so that only the first counter is printed and all others are marked merged. The reordering for groups breaks the assumption and so all counts are printed. This change removes the assumption from collect_all_aliases that the events are in blocks and instead processes the entire evlist.
