2023-12-17selftests/net: Add TCP-AO libraryDmitry Safonov12-0/+2797
Provide functions to create selftests dedicated to TCP-AO. They can run in parallel, as they use temporary net namespaces. They can be very specific to the feature being tested. This will allow to create a lot of TCP-AO tests, without complicating one binary with many --options and to create scenarios, that are hard to put in bash script that uses one binary.

2023-12-15selftests/bpf: Don't use libbpf_get_error() in kprobe_multi_testHou Tao1-5/+11
Since libbpf v1.0, libbpf doesn't return error code embedded into the pointer iteself, libbpf_get_error() is deprecated and it is basically the same as using -errno directly. So replace the invocations of libbpf_get_error() by -errno in kprobe_multi_test. For libbpf_get_error() in test_attach_api_fails(), saving -errno before invoking ASSERT_xx() macros just in case that errno is overwritten by these macros. However, the invocation of libbpf_get_error() in get_syms() should be kept intact, because hashmap__new() still returns a pointer with embedded error code.

2023-12-15tools/testing/nvdimm: Add compile-test coverage for ndtestDan Williams1-0/+1
Greg lamented: "Ick, sorry about that, obviously this test isn't actually built by any bots :(" A quick and dirty way to prevent this problem going forward is to always compile ndtest.ko whenever nfit_test is built. While this still does not expose the test code to any of the known build bots, it at least makes it the case that anyone that runs the x86 tests also compiles the powerpc test. I.e. the Intel NVDIMM maintainers are less likely to fall into this hole in the future.

vmlinux.h declarations are more ergnomic, especially when working with kfuncs. The uapi headers are often incomplete for kfunc definitions. This commit also switches bitfield accesses to use CO-RE helpers. Switching to vmlinux.h definitions makes the verifier very unhappy with raw bitfield accesses. The error is: ; md.u.md2.dir = direction; 33: (69) r1 = *(u16 *)(r2 +11) misaligned stack access off (0x0; 0x0)+-64+11 size 2 Fix by using CO-RE-aware bitfield reads and writes.

2023-12-14selftests/bpf: Remove flaky test_btf_id testYonghong Song1-5/+0
With previous patch, one of subtests in test_btf_id becomes flaky and may fail. The following is a failing example: Error: #26 btf Error: #26/174 btf/BTF ID Error: #26/174 btf/BTF ID btf_raw_create:PASS:check 0 nsec btf_raw_create:PASS:check 0 nsec test_btf_id:PASS:check 0 nsec ... test_btf_id:PASS:check 0 nsec test_btf_id:FAIL:check BTF lingersdo_test_get_info:FAIL:check failed: -1 The test tries to prove a btf_id not available after the map is closed. But btf_id is freed only after workqueue and a rcu grace period, compared to previous case just after a rcu grade period. Depending on system workload, workqueue could take quite some time to execute function bpf_map_free_deferred() which may cause the test failure. Instead of adding arbitrary delays, let us remove the logic to check btf_id availability after map is closed.

2023-12-14perf top: Uniform the event name for the hybrid machineKan Liang4-27/+28
It's hard to distinguish the default cycles events among hybrid PMUs. For example, $ perf top Available samples 385 cycles:P 903 cycles:P The other tool, e.g., perf record, uniforms the event name and adds the hybrid PMU name before opening the event. So the events can be easily distinguished. Apply the same methodology for the perf top as well. The evlist__uniquify_name() will be invoked by both record and top.

2023-12-14perf top: Use evsel's cpus to replace user_requested_cpusKan Liang1-2/+2
perf top errors out on a hybrid machine $perf top Error: The cycles:P event is not supported. The perf top expects that the "cycles" is collected on all CPUs in the system. But for hybrid there is no single "cycles" event which can cover all CPUs. Perf has to split it into two cycles events, e.g., cpu_core/cycles/ and cpu_atom/cycles/. Each event has its own CPU mask. If a event is opened on the unsupported CPU. The open fails. That's the reason of the above error out. Perf should only open the cycles event on the corresponding CPU. The commit ef91871c960e ("perf evlist: Propagate user CPU maps intersecting core PMU maps") intersect the requested CPU map with the CPU map of the PMU. Use the evsel's cpus to replace user_requested_cpus. The evlist's threads are also propagated to the evsel's threads in __perf_evlist__propagate_maps(). For a system-wide event, perf appends a dummy event and assign it to the evsel's threads. For a per-thread event, the evlist's thread_map is assigned to the evsel's threads. The same as the other tools, e.g., perf record, using the evsel's threads when opening an event.

2023-12-14perf unwind-libunwind: Fix base address for .eh_frameNamhyung Kim1-1/+1
The base address of a DSO mapping should start at the start of the file. Usually DSOs are mapped from the pgoff 0 so it doesn't matter when it uses the start of the map address. But generated DSOs for JIT codes doesn't start from the 0 so it should subtract the offset to calculate the .eh_frame table offsets correctly.

2023-12-14perf unwind-libdw: Handle JIT-generated DSOs properlyNamhyung Kim1-4/+17
Usually DSOs are mapped from the beginning of the file, so the base address of the DSO can be calculated by map->start - map->pgoff. However, JIT DSOs which are generated by `perf inject -j`, are mapped only the code segment. This makes unwind-libdw code confusing and rejects processing unwinds in the JIT DSOs. It should use the map start address as base for them to fix the confusion.

Ensure that the expected value for valid_entries for the SEND_RECEIVE_UNALIGNED test equals the total number of packets sent, which is 4096. Create a new function called pkt_stream_pkt_set() that allows for packet modification to meet specific requirements while ensuring the accurate maintenance of the valid packet count to prevent inconsistencies in packet tracking.

Unfortunately, this approach is incompatible with AF_XDP on TX side, because VLAN interfaces do not have such feature. Check both packets sent via AF_XDP TX and regular socket. AF_INET packet will also have a filled-in hash type (XDP_RSS_TYPE_L4), unlike AF_XDP packet, so more values can be checked.
