PATCH 1/6 selftests/livepatch: fix test-callbacks.sh execution error

The script test-callbacks.sh fails with the following error:

$ sudo ./test-callbacks.sh

ERROR: livepatch kselftest(s) failed

The issue arises due to a mismatch in expected log output during livepatch transition. Specifically, the logs previously contained "livepatch:" but have now been updated to "transition:". This results in test failures when comparing the output with the expected values.

This patch updates the expected test output to reflect the new log format.

% rmmod test_klp_livepatch

ERROR: livepatch kselftest(s) failed

The issue arises due to a mismatch in expected log output during livepatch transition. Specifically, the logs previously contained "livepatch:" but have now been updated to "transition:". This results in test failures when comparing the output with the expected values.

This patch updates the expected test output to reflect the new log format.

PATCH 6/6 selftests/livepatch: fix test-sysfs.sh execution error

In reply to George Guo

From: George Guo <[email protected]>

The script test-sysfs.sh fails with the following error:

$ sudo ./test-sysfs.sh
TEST: sysfs test ... not ok

ERROR: livepatch kselftest(s) failed

The issue arises due to a mismatch in expected log output during livepatch transition. Specifically, the logs previously contained "livepatch:" but have now been updated to "transition:". This results in test failures when comparing the output with the expected values.

This patch updates the expected test output to reflect the new log format.

are you sure? I have just run livepatch selftests on v6.12 and everything was fine.

The above suggests that something happened to KBUILD_MODNAME in your case (which would also mean that the fix should be different). Could you verify or provide more information, please?
