tools/testing/selftests: add self-test for verifying load alignment

2020-10-16T18:11:21Z

This produces a PIE binary with a variety of p_align requirements, suitable for verifying that the load address meets that alignment requirement.

selftests/exec: Verify execve of non-regular files fail

2020-05-22T15:29:00Z

Add a named pipe as an exec target to make sure that non-regular files are rejected by execve() with EACCES. This can help verify commit 73601ea5b7b1 ("fs/open.c: allow opening only regular files during execve()"). Signed-off-by: Kees Cook Signed-off-by: Shuah Khan

selftests/exec: Add binfmt_script regression test

2020-05-21T15:24:39Z

While working on commit b5372fe5dc84 ("exec: load_script: Do not exec truncated interpreter path"), I wrote a series of test scripts to verify corner cases. However, soon after, commit 6eb3c3d0a52d ("exec: increase BINPRM_BUF_SIZE to 256") landed, resulting in the tests needing to be refactored for the larger BINPRM_BUF_SIZE, which got lost on my TODO list. During the recent exec refactoring work[1], the need for these tests resurfaced, so I've finished them up for addition to the kernel selftests.

selftests: exec: return Kselftest Skip code for skipped tests

2018-05-30T21:21:52Z

When execveat test is skipped because of unmet dependencies and/or unsupported configuration, it exits with error which is treated as a fail by the Kselftest framework. This leads to false negative result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Change it to use ksft_exit_skip() when kernel doesn't support execveat. Signed-off-by: Shuah Khan (Samsung OSG)
