[PATCH bpf-next v2 0/4] Retire test_sock.c

by Jordan Rife

This patch series migrates test cases out of test_sock.c to prog_tests-style tests. It moves all BPF_CGROUP_INET4_POST_BIND and BPF_CGROUP_INET6_POST_BIND test cases into a new prog_test, sock_post_bind.c, while reimplementing all LOAD_REJECT test cases as verifier tests in progs/verifier_sock.c. Finally, it moves remaining BPF_CGROUP_INET_SOCK_CREATE test coverage into prog_tests/sock_create.c before retiring test_sock.c completely. Changes ======= v1->v2: - Remove superfluous verbose bool from the top of sock_post_bind.c. - Use ASSERT_OK_FD instead of ASSERT_GE to test cgroup_fd validity. - Run sock_post_bind tests in their own namespace, "sock_post_bind".

This patch introduces two changes. A new kunit test, and a bug fix. Without the bug fix, the new kunit test fails. I usually prefer separating test changes from fixes (introduc a fix first, and then the test for it, to avoid unnecessary test failures). But, given the small size and the simplicity of the kunit change for this patch, I think introducing it together with the fix is ok. > > # ./tools/testing/kunit/kunit.py run damon-operations > [...] > ============== damon-operations (6 subtests) =============== > [PASSED] damon_test_three_regions_in_vmas > [PASSED] damon_test_apply_three_regions1 > [PASSED] damon_test_apply_three_regions2 > [PASSED] damon_test_apply_three_regions3 > [PASSED] damon_test_apply_three_regions4 > [PASSED] damon_test_split_evenly > ================ [PASSED] damon-operations ================= > > Fixes: 3f49584b262c ("mm/damon: implement primitives for the virtual memory address spaces") > Signed-off-by: Zheng Yejian <zhengyejian(a)huaweicloud.com> Reviewed-by: SeongJae Park <sj(a)kernel.org> Thanks, SJ [...]

[PATCH v5 0/3] selftests: livepatch: test livepatching a kprobed function

by Michael Vetter

Thanks for all the reviews. V5: Replace /sys/kernel/livepatch also in other/already existing tests. Improve commit message of 3rd patch. V4: Use variable for /sys/kernel/debug. Be consistent with "" around variables. Fix path in commit message to /sys/kernel/debug/kprobes/enabled. V3: Save and restore kprobe state also when test fails, by integrating it into setup_config() and cleanup(). Rename SYSFS variables in a more logical way. Sort test modules in alphabetical order.

[PATCH net-next 8/8] selftests: net: fdb_notify: Add a test for FDB notifications

by Petr Machata

Check that only one notification is produced for various FDB edit operations. Regarding the ip_link_add() and ip_link_master() helpers. This pattern of action plus corresponding defer is bound to come up often, and a dedicated vocabulary to capture it will be handy. tunnel_create() and vlan_create() from forwarding/lib.sh are somewhat opaque and perhaps too kitchen-sinky, so I tried to go in the opposite direction with these ones, and wrapped only the bare minimum to schedule a corresponding cleanup.

[PATCH net-next 6/8] selftests: net: lib: Move checks from forwarding/lib.sh here

by Petr Machata

For logging to be useful, something has to set RET and retmsg by calling ret_set_ksft_status(). There is a suite of functions to that end in forwarding/lib: check_err, check_fail et.al. Move them to net/lib.sh so that every net test can use them. Existing lib.sh users might be using these same names for their functions. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.

[PATCH net-next 5/8] selftests: net: lib: Move tests_run from forwarding/lib.sh here

by Petr Machata

It would be good to use the same mechanism for scheduling and dispatching general net tests as the many forwarding tests already use. To that end, move the logging helpers to net/lib.sh so that every net test can use them. Existing lib.sh users might be using the name themselves. However lib.sh is always sourced near the top of the file (checked), and whatever new definition will simply override the one provided by lib.sh.
