2020-09-17selftests/timers: Turn off timeout settingPo-Hsu Lin
commit 5c1e4f7e9e49b6925b1fb5c507d2c614f3edb292 upstream. The following 4 tests in timers can take longer than the default 45 seconds that added in commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") to run: * nsleep-lat - 2m7.350s * set-timer-lat - 2m0.66s * inconsistency-check - 1m45.074s * raw_skew - 2m0.013s Thus they will be marked as failed with the current 45s setting: not ok 3 selftests: timers: nsleep-lat # TIMEOUT not ok 4 selftests: timers: set-timer-lat # TIMEOUT not ok 6 selftests: timers: inconsistency-check # TIMEOUT not ok 7 selftests: timers: raw_skew # TIMEOUT Disable the timeout setting for timers can make these tests finish properly: ok 3 selftests: timers: nsleep-lat ok 4 selftests: timers: set-timer-lat ok 6 selftests: timers: inconsistency-check ok 7 selftests: timers: raw_skew https://bugs.launchpad.net/bugs/1864626 Fixes: 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") Signed-off-by: Po-Hsu Lin <po-hsu.lin@canonical.com> Acked-by: John Stultz <john.stultz@linaro.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2020-09-04selftests/powerpc: Fix online CPU selectionSandipan Das
commit dfa03fff86027e58c8dba5c03ae68150d4e513ad upstream. The size of the CPU affinity mask must be large enough for systems with a very large number of CPUs. Otherwise, tests which try to determine the first online CPU by calling sched_getaffinity() will fail. This makes sure that the size of the allocated affinity mask is dependent on the number of CPUs as reported by get_nprocs_conf().

commit 47e33c05f9f07cac3de833e531bcac9ae052c7ca upstream. When SECCOMP_IOCTL_NOTIF_ID_VALID was first introduced it had the wrong direction flag set.

commit 16f6458f2478b55e2b628797bc81a4455045c74e upstream. The msg_zerocopy test pins the sender and receiver threads to separate cores to reduce variance between runs. But it hardcodes the cores and skips core 0, so it fails on machines with the selected cores offline, or simply fewer cores. The test mainly gives code coverage in automated runs. The throughput of zerocopy ('-z') and non-zerocopy runs is logged for manual inspection. Continue even when sched_setaffinity fails. Just log to warn anyone interpreting the data.

commit f43cb0d672aa8eb09bfdb779de5900c040487d1d upstream. Fix sockmap tests which rely on old bpf_prog_dispatch behaviour. In the first case, the tests check that detaching without giving a program succeeds. Since these are not the desired semantics, invert the condition.

2020-07-07selftests/bpf: fix endianness issues in test_sysctlIlya Leoshkevich
commit 3ec2a0ed3fec4ec8b27d9b71fdcbc1c30d1542d3 upstream. A lot of test_sysctl sub-tests fail due to handling strings as a bunch of immediate values in a little-endian-specific manner. Fix by wrapping all immediates in bpf_ntohl and the new bpf_be64_to_cpu. fixup_sysctl_value() dynamically writes an immediate, and thus should be endianness-aware. Implement this by simply memcpy()ing the raw user-provided value, since testcase endianness and bpf program endianness match.

2020-06-08selftests: fix flower parent qdiscVlad Buslov
commit 0531b0357ba37464e5c0033e1b7c69bbf5ecd8fb upstream. Flower tests used to create ingress filter with specified parent qdisc "parent ffff:" but dump them on "ingress". With recent commit that fixed tcm_parent handling in dump those are not considered same parent anymore, which causes iproute2 tc to emit additional "parent ffff:" in first line of filter dump output. The change in output causes filter match in tests to fail. Prevent parent qdisc output when dumping filters in flower tests by always correctly specifying "ingress" parent both when creating and dumping filters.

2020-06-08ftrace/selftest: make unresolved cases cause failure if --fail-unresolved setAlan Maguire
commit b730d668138cb3dd9ce78f8003986d1adae5523a upstream. Currently, ftracetest will return 1 (failure) if any unresolved cases are encountered. The unresolved status results from modules and programs not being available, and as such does not indicate any issues with ftrace itself. As such, change the behaviour of ftracetest in line with unsupported cases; if unsupported cases happen, ftracetest still returns 0 unless --fail-unsupported. Here --fail-unresolved is added and the default is to return 0 if unresolved results occur.

kernel test robot found a warning when build bpf selftest for 5.4.y stable tree: prog_tests/stacktrace_build_id_nmi.c:55:3: error: label ‘cleanup’ used but not defined goto cleanup; ^~~~ This is because we are lacking upstream commit dde53c1b763b ("selftests/bpf: Convert few more selftest to skeletons").

2020-06-08selftests/ftrace: Check the first record for kprobe_args_type.tcXiao Yang
commit f0c0d0cf590f71b2213b29a7ded2cde3d0a1a0ba upstream. It is possible to get multiple records from trace during test and then more than 4 arguments are assigned to ARGS. This situation results in the failure of kprobe_args_type.tc. For example: ----------------------------------------------------------- grep testprobe trace ftracetest-5902 [001] d... 111195.682227: testprobe: (_do_fork+0x0/0x460) arg1=334823024 arg2=334823024 arg3=0x13f4fe70 arg4=7 pmlogger-5949 [000] d... 111195.709898: testprobe: (_do_fork+0x0/0x460) arg1=345308784 arg2=345308784 arg3=0x1494fe70 arg4=7 grep testprobe trace sed -e 's/.* arg1=\(.*\) arg2=\(.*\) arg3=\(.*\) arg4=\(.*\)/\1 \2 \3 \4/' ARGS='334823024 334823024 0x13f4fe70 7 345308784 345308784 0x1494fe70 7' ----------------------------------------------------------- We don't care which process calls do_fork so just check the first record to fix the issue.

2020-06-08ftrace/selftests: workaround cgroup RT scheduling issuesAlan Maguire
commit 57c4cfd4a2eef8f94052bd7c0fce0981f74fb213 upstream. wakeup_rt.tc and wakeup.tc tests in tracers/ subdirectory fail due to the chrt command returning: chrt: failed to set pid 0's policy: Operation not permitted. To work around this, temporarily disable grout RT scheduling during ftracetest execution. Restore original value on test run completion. With these changes in place, both tests consistently pass.

2020-06-04selftests/ipc: Fix test failure seen after initial test runTyler Hicks
commit b87080eab4c1377706c113fc9c0157f19ea8fed1 upstream. After successfully running the IPC msgque test once, subsequent runs result in a test failure: $ sudo ./run_kselftest.sh TAP version 13 1..1 # selftests: ipc: msgque # Failed to get stats for IPC queue with id 0 # Failed to dump queue: -22 # Bail out! # # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0 not ok 1 selftests: ipc: msgque # exit=1 The dump_queue() function loops through the possible message queue index values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id represents the index value. The first time the test is ran, the initial index value of 0 is valid and the test is able to complete. The index value of 0 is not valid in subsequent test runs and the loop attempts to try index values of 1, 2, 3, and so on until a valid index value is found that corresponds to the message queue created earlier in the test. The msgctl() syscall returns -1 and sets errno to EINVAL when invalid index values are used. The test failure is caused by incorrectly comparing errno to -EINVAL when cycling through possible index values. Fix invalid test failures on subsequent runs of the msgque test by correctly comparing errno values to a non-negated EINVAL.

commit b43e78f65b1d35fd3e13c7b23f9b64ea83c9ad3a upstream. As the ftrace selftests can run for a long period of time, disable the timeout that the general selftests have. If a selftest hangs, then it probably means the machine will hang too.

2020-06-01bpf: Test_progs, add test to catch retval refine error handlingJohn Fastabend
commit d2db08c7a14e0b5eed6132baf258b80622e041a9 upstream. Before this series the verifier would clamp return bounds of bpf_get_stack() to [0, X] and this led the verifier to believe that a JMP_JSLT 0 would be false and so would prune that path. The result is anything hidden behind that JSLT would be unverified. Add a test to catch this case by hiding an goto pc-1 behind the check which will cause an infinite loop if not rejected.
