kselftest/seccomp: Report each expectation we assert as a KTAP test

2024-01-30T15:55:42Z

The seccomp benchmark test makes a number of checks on the performance it measures and logs them to the output but does so in a custom format which none of the automated test runners understand meaning that the chances that anyone is paying attention are slim. Let's additionally log each result in KTAP format so that automated systems parsing the test output will see each comparison as a test case. The original logs are left in place since they provide the actual numbers for analysis. As part of this rework the flow for the main program so that when we skip tests we still log all the tests we skip, this is because the standard KTAP headers and footers include counts of the number of expected and run tests.

kselftest/seccomp: Use kselftest output functions for benchmark

2024-01-30T15:55:42Z

In preparation for trying to output the test results themselves in TAP format rework all the prints in the benchmark to use the kselftest output functions. The uses of system() all produce single line output so we can avoid having to deal with fully managing the child process and continue to use system() by simply printing an empty message before we invoke system(). We also leave one printf() used to complete a line of output in place. Tested-by: Anders Roxell Acked-by: Kees Cook Signed-off-by: Mark Brown Signed-off-by: Shuah Khan

selftests/seccomp: Handle arm32 corner cases better

2023-08-10T20:26:19Z

It turns out arm32 doesn't handle syscall -1 gracefully, so skip testing for that. Additionally skip tests that depend on clone3 when it is not available (for example when building the seccomp selftests on an old arm image without clone3 headers). And improve error reporting for when nanosleep fails, as seen on arm32 since v5.15. Cc: Lecopzer Chen Signed-off-by: Kees Cook

selftests: seccomp: Fix incorrect kernel headers search path

2023-02-13T16:09:45Z

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents building against kernel headers from the build environment in scenarios where kernel headers are installed into a specific output directory (O=...).

selftests/seccomp: Check CAP_SYS_ADMIN capability in the test mode_filter_without_nnp

2022-12-02T19:32:53Z

In the "mode_filter_without_nnp" test in seccomp_bpf, there is currently a TODO which asks to check the capability CAP_SYS_ADMIN instead of euid. This patch adds support to check if the calling process has the flag CAP_SYS_ADMIN, and also if this flag has CAP_EFFECTIVE set.
