If you are not using the test-definitions project to run kselftest, please ignore this email.

A new run script for kselftest, run_kselftest.sh [1], was created during the Linux v5.10 release.

This script allows someone to run both individual test cases and sets of test cases. Accordingly, the test-definitions kselftest script [2] was also improved to support these upstream changes [1]. Currently this change is in the test-definitions repository in a separate branch "kselftest". This has been running in LKFT's CI since November 2020 [3].

The test-definitions kselftest script will stop supporting older versions of the kselftest run script starting 1st-Feb-2021 from master branch. OTOH, One have to use test-definitions Tag 2021.01 (will be created) for older kselftest versions.

We request that any users of test-definitions project start updating your kselftest sources to version v5.10 and above.

From: Kees Cook keescook@chromium.org Date: Mon, 28 Sep 2020 13:26:49 -0700 Subject: selftests/run_kselftest.sh: Make each test individually selectable

Currently with run_kselftest.sh there is no way to choose which test we could run. All the tests listed in kselftest-list.txt are all run every time. This patch enhanced the run_kselftest.sh to make the test collections (or tests) individually selectable. e.g.:

$ ./run_kselftest.sh -c seccomp -t timers:posix_timers -t timers:nanosleep

Additionally adds a way to list all known tests with "-l", usage with "-h", and perform a dry run without running tests with "-n".
