* selftests/harness: Allow test to configure timeoutAlexandre Belloni2019-05-241-5/+12
| | | | | | | | | | | Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per test") adds an hardcoded 30s timeout to all tests. Unfortunately, rtctest has two tests taking up to 60s. Allow for individual tests to define their own timeout.

* selftests/harness: Add 30 second timeout per testKees Cook2019-04-161-0/+2
| | | | | | | | | In order to keep tests from hanging forever, this adds an alarm signal to each test run. This assumes an individual test doesn't take longer than 30 seconds. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

* selftests: do not macro-expand failed assertion expressionsDmitry V. Levin2018-12-101-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've stumbled over the current macro-expand behaviour of the test harness: $ gcc -Wall -xc - <<'__EOF__' TEST(macro) { int status = 0; ASSERT_TRUE(WIFSIGNALED(status)); } TEST_HARNESS_MAIN __EOF__ $ ./a.out [==========] Running 1 tests from 1 test cases. [ RUN ] global.macro <stdin>:4:global.macro:Expected 0 (0) != (((signed char) (((status) & 0x7f) + 1) >> 1) > 0) (0) global.macro: Test terminated by assertion [ FAIL ] global.macro [==========] 0 / 1 tests passed. [ FAILED ] With this change the output of the same test looks much more comprehensible: [==========] Running 1 tests from 1 test cases. [ RUN ] global.macro <stdin>:4:global.macro:Expected 0 (0) != WIFSIGNALED(status) (0) global.macro: Test terminated by assertion [ FAIL ] global.macro [==========] 0 / 1 tests passed. [ FAILED ] The issue is very similar to the bug fixed in glibc assert(3) three years ago: https://sourceware.org/bugzilla/show_bug.cgi?id=18604 Cc: Shuah Khan <shuah@kernel.org> Cc: Kees Cook <keescook@chromium.org> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Will Drewry <wad@chromium.org> Cc: linux-kselftest@vger.kernel.org Signed-off-by: Dmitry V.

* selftests: Enhance kselftest_harness.h to print which assert failedMickaël Salaün2017-09-051-5/+34
| | | | | | | | | | | | | | | | | | | When a test process is not able to write to TH_LOG_STREAM, this step mechanism enable to print the assert number which triggered the failure. This can be enabled by setting _metadata->no_print to true at the beginning of the test sequence. Update the seccomp-bpf test to return 0 if a test succeeded. This feature is needed for the Landlock tests.
