The selftests depend on using the shell exit code as a mean of detecting the success or failure of test-binary executed. The appropiate output "[PASS]" or "[FAIL]" in generated by tools/testing/selftests/lib.mk. Notice that the exit code is masked with 255. Thus, be careful if using the number of errors as the exits code, as 256 errors would be seen as a success. There are two standard defined exit(3) codes: /usr/include/stdlib.h #define EXIT_FAILURE 1 /* Failing exit status. */ #define EXIT_SUCCESS 0 /* Successful exit status. */ Fix test_verifier.c to not use the negative value of variable "results", but instead return EXIT_FAILURE. Fix test_align.c and test_progs.c to actually use exit codes, before they were always indicating success regardless of results. Signed-off-by: Jesper Dangaard Brouer <brouer@xxxxxxxxxx>
