This is the third version of the patchset, now with far less changes. There are still somethings that I would like to work next, like adapting the newest test introduced in the last submsision, but this is something for a new iteration.
Original cover-letter: These patches don't really change how the patches are run, just skip some tests on kernels that don't support a feature (like kprobe and livepatched living together) or when a livepatch sysfs attribute is missing. These patches are based on printk/for-next branch. Please review! Thanks! Signed-off-by: Marcos Paulo de Souza <[email protected]> --- Changes in v3: - Patch 1 was changed to reorganize the ifdeffery to handle multiple archs syscall wrapper (Miroslav) - Patch 3 was changed to rework the commit message and to address function naming (Joe) - Patches 4, 5 and 6 where had the commit messages to include the kernel version where the given sysfs attributes were included (Petr Mladek) - Link to v2: https://patch.msgid.link/[email protected] Changes in v2: - Patch descriptions were changed to remove "test-X", since it was polluting the commit subjects (Miroslav Benes) - Patch 8 was dropped since it was checking for a message from an out-of-tree patch. (Petr Mladek) - Patch 3 was dropped as should be treated as expected failure for older kernels. (Petr Mladek) - Patch 2 was changed to use y/n instead of 1/0, since it's more natural to use it. - Patch 1 was changed to handle ppc and loongson, and error out if dealing with a different architecture that sets CONFIG_ARCH_HAS_SYSCALL_WRAPPER and haven't changed the test to include the proper wrapper prefix. - Patch 4 was changed to invert the return of the bash function to return 1 in failure, like a normal bash function (Joe Lawrence) - Patches 5, 6 an 7 were changed to not split the tests, but to only run the tests when the attribute were present (Miroslav Benes) - Link to v1: https://patch.msgid.link/[email protected] --- Marcos Paulo de Souza (6): selftests: livepatch: Check for ARCH_HAS_SYSCALL_WRAPPER config selftests: livepatch: Replace true/false module parameter by y/n selftests: livepatch: Introduce does_sysfs_exist function selftests: livepatch: Check if patched sysfs attribute exists selftests: livepatch: Check if replace sysfs attribute exists selftests: livepatch: Check if stack_order sysfs attribute exists tools/testing/selftests/livepatch/functions.sh | 10 ++ tools/testing/selftests/livepatch/test-kprobe.sh | 8 +- tools/testing/selftests/livepatch/test-sysfs.sh | 120 ++++++++++++--------- .../livepatch/test_modules/test_klp_syscall.c | 27 +++-- 4 files changed, 104 insertions(+), 61 deletions(-) --- base-commit: b8e6ad22f78aa279dece2f86efe6429953d36452 change-id: 20260309-lp-tests-old-fixes-f955abc8ec27 Best regards, -- Marcos Paulo de Souza <[email protected]>
