Building with clang/LLVM 23 breaks several selftests. Patches #1 to #4 fix those failures.
The following self-tests also fail under specific invocations of test_progs: - ./test_progs -t prog_tests_framework/test_fail -v test_prog_tests_framework:FAIL:skip_cnt_check unexpected skip_cnt_check: actual 0 != expected 2 - ./test_progs -t prog_tests_framework_expected_msgs -v Caught signal #11! - ./test_progs -t prog_tests_framework_compare_text -v Caught signal #11! Patches #5 to #7 fix these. Changes in v2: - Collect the selftest fixes from the two patches in v1 patches: #1, #5, #6 and #7. - Add three new patches: #2, #3 and #4.
