selftests/exec: Convert remaining /bin/sh to /bin/bash

2024-03-18T18:19:37Z

As was intended with commit 17107429947b ("selftests/exec: Perform script checks with /bin/bash"), convert the other instance of /bin/sh to /bin/bash. It appears that at least Debian Bookworm's /bin/sh (dash) does not conform to POSIX's "return 127 when script not found" requirement.

selftests/exec: Perform script checks with /bin/bash

2024-03-06T00:06:01Z

It seems some shells linked to /bin/sh don't have consistent behavior with error codes on execution failures. Explicitly use /bin/bash so that "not found" errors are correctly generated. Repeating the comment from the test: /* * Execute as a long pathname relative to "/". If this is a script, * the interpreter will launch but fail to open the script because its * name ("/dev/fd/5/xxx....") is bigger than PATH_MAX. * * The failure code is usually 127 (POSIX: "If a command is not found, * the exit status shall be 127."), but some systems give 126 (POSIX: * "If the command name is found, but it is not an executable utility, * the exit status shall be 126."), so allow either. */ Reported-by: Muhammad Usama Anjum Closes: https://lore.kernel.org/lkml/02c8bf8e-1934-44ab-a886-e065b37366a7@collabora.com/ Signed-off-by: Kees Cook --- Cc: Eric Biederman Cc: Shuah Khan Cc: Mark Brown Cc: linux-mm@kvack.org Cc: linux-kselftest@vger.kernel.org

selftests/exec: Convert execveat test to generate KTAP output

2023-10-05T20:50:03Z

Currently the execveat test does not produce KTAP output but rather a custom format. This means that we only get a pass/fail for the suite, not for each individual test that the suite does. Convert to using the standard kselftest output functions which result in KTAP output being generated. The main trick with this is that, being an exec() related test, the program executes itself and returns specific exit codes to verify success meaning that we need to only use the top level kselftest header/summary functions when invoked directly rather than when run as part of a test.
