2024-04-11perf annotate: Make sure to call symbol__annotate2() in TUINamhyung Kim2-1/+4
The symbol__annotate2() initializes some data structures needed by TUI. It has a logic to prevent calling it multiple times by checking if it has the annotated source. But data type profiling uses a different code (symbol__annotate) to allocate the annotated lines in advance. So TUI missed to call symbol__annotate2() when it shows the annotation browser. Make symbol__annotate() reentrant and handle that situation properly. This fixes a crash in the annotation browser started by perf report in TUI like below. $ perf report -s type,sym --tui # and press 'a' key and then move down Fixes: 81e57deec325 ("perf report: Support data type profiling") Reviewed-by: Ian Rogers <irogers@google.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20240405211800.1412920-2-namhyung@kernel.org

2024-04-02mptcp: don't account accept() of non-MPC client as fallback to TCPDavide Caratti1-0/+9
Current MPTCP servers increment MPTcpExtMPCapableFallbackACK when they accept non-MPC connections. As reported by Christoph, this is "surprising" because the counter might become greater than MPTcpExtMPCapableSYNRX. MPTcpExtMPCapableFallbackACK counter's name suggests it should only be incremented when a connection was seen using MPTCP options, then a fallback to TCP has been done. Let's do that by incrementing it when the subflow context of an inbound MPC connection attempt is dropped. Also, update mptcp_connect.sh kselftest, to ensure that the above MIB does not increment in case a pure TCP client connects to a MPTCP server.

2024-03-30selftest: tcp: Add bind() tests for SO_REUSEADDR/SO_REUSEPORT.Kuniyuki Iwashima1-6/+257
This patch adds two tests using SO_REUSEADDR and SO_REUSEPORT and defines errno for each test case. SO_REUSEADDR/SO_REUSEPORT is set for the per-fixture two bind() calls. The notable pattern is the pair of v6only [::] and plain [::]. The two sockets are put into the same tb2, where per-bucket v6only flag would be useless to detect bind() conflict.

Currently, bind_wildcard.c calls bind() twice for two addresses and checks the pre-defined errno against the 2nd call. Also, the two bind() calls are swapped to cover various patterns how bind buckets are created. However, only testing two addresses is insufficient to detect regression. So, we will add more bind() calls, and then, we need to define different errno for each bind() per test case. As a prepartion, let's define the reverse order bind() test cases as fixtures.

2024-03-29selftests/seccomp: Try to fit runtime of benchmark into timeoutMark Brown1-1/+1
The seccomp benchmark runs five scenarios, one calibration run with no seccomp filters enabled then four further runs each adding a filter. The calibration run times itself for 15s and then each additional run executes for the same number of times. Currently the seccomp tests, including the benchmark, run with an extended 120s timeout but this is not sufficient to robustly run the tests on a lot of platforms. Sample timings from some recent runs: Platform Run 1 Run 2 Run 3 Run 4 --------- ----- ----- ----- ----- PowerEdge R200 16.6s 16.6s 31.6s 37.4s BBB (arm) 20.4s 20.4s 54.5s Synquacer (arm64) 20.7s 23.7s 40.3s The x86 runs from the PowerEdge are quite marginal and routinely fail, for the successful run reported here the timed portions of the run are at 117.2s leaving less than 3s of margin which is frequently breached. The added overhead of adding filters on the other platforms is such that there is no prospect of their runs fitting into the 120s timeout, especially on 32 bit arm where there is no BPF JIT. While we could lower the time we calibrate for I'm also already seeing the currently completing runs reporting issues with the per filter overheads not matching expectations: Let's instead raise the timeout to 180s which is only a 50% increase on the current timeout which is itself not *too* large given that there's only two tests in this suite.

2024-03-29selftests/ftrace: Fix event filter target_func selectionMark Rutland1-1/+1
The event filter function test has been failing in our internal test farm: | # not ok 33 event filter function - test event filtering on functions Running the test in verbose mode indicates that this is because the test erroneously determines that kmem_cache_free() is the most common caller of kmem_cache_free(): # # + cut -d: -f3 trace # # + sed s/call_site=([^+]*)+0x.*/1/ # # + sort # # + uniq -c # # + sort # # + tail -n 1 # # + sed s/^[ 0-9]*// # # + target_func=kmem_cache_free ... and as kmem_cache_free() doesn't call itself, setting this as the filter function for kmem_cache_free() results in no hits, and consequently the test fails: # # + grep kmem_cache_free trace # # + grep kmem_cache_free # # + wc -l # # + hitcnt=0 # # + grep kmem_cache_free trace # # + grep -v kmem_cache_free # # + wc -l # # + misscnt=0 # # + [ 0 -eq 0 ] # # + exit_fail This seems to be because the system in question has tasks with ':' in their name (which a number of kernel worker threads have). These show up in the trace, e.g. test:.sh-1299 [004] ..... 2886.040608: kmem_cache_free: call_site=putname+0xa4/0xc8 ptr=000000000f4d22f4 name=names_cache ... and so when we try to extact the call_site with: cut -d: -f3 trace | sed 's/call_site=\([^+]*\)+0x.*/\1/' ... the 'cut' command will extrace the column containing 'kmem_cache_free' rather than the column containing 'call_site=...', and the 'sed' command will leave this unchanged. Consequently, the test will decide to use 'kmem_cache_free' as the filter function, resulting in the failure seen above. Fix this by matching the 'call_site=<func>' part specifically to extract the function name.

2024-03-27bpf: Check bloom filter map value sizeAndrei Matei1-0/+6
This patch adds a missing check to bloom filter creating, rejecting values above KMALLOC_MAX_SIZE. This brings the bloom map in line with many other map types. The lack of this protection can cause kernel crashes for value sizes that overflow int's. Such a crash was caught by syzkaller. The next patch adds more guard-rails at a lower level.

The longest running netdevsim test, nexthop.sh, currently takes 5 min to finish. Around 260s to be exact, and 310s on a debug kernel. The default timeout in selftest is 45sec, so we need an explicit config. Give ourselves some headroom and use 10min. Commit under Fixes isn't really to "blame" but prior to that netdevsim tests weren't integrated with kselftest infra so blaming the tests themselves doesn't seem right, either.

2024-03-26selftests: vxlan_mdb: Fix failures with old libnetIdo Schimmel1-77/+128
Locally generated IP multicast packets (such as the ones used in the test) do not perform routing and simply egress the bound device. However, as explained in commit 8bcfb4ae4d97 ("selftests: forwarding: Fix failing tests with old libnet"), old versions of libnet (used by mausezahn) do not use the "SO_BINDTODEVICE" socket option. Specifically, the library started using the option for IPv6 sockets in version 1.1.6 and for IPv4 sockets in version 1.2. This explains why on Ubuntu - which uses version 1.1.6 - the IPv4 overlay tests are failing whereas the IPv6 ones are passing. Fix by specifying the source and destination MAC of the packets which will cause mausezahn to use a packet socket instead of an IP socket.
