From: George Guo <guodongtai@xxxxxxxxxx> The script test-syscall.sh fails with the following error: $ sudo ./test-syscall.sh TEST: patch getpid syscall while being heavily hammered ... not ok - expected + result % insmod test_modules/test_klp_syscall.ko klp_pids=18484,18485,18486,18487,18488,18489,18490,... livepatch: enabling patch 'test_klp_syscall' -livepatch: 'test_klp_syscall': initializing patching transition -livepatch: 'test_klp_syscall': starting patching transition -livepatch: 'test_klp_syscall': completing patching transition -livepatch: 'test_klp_syscall': patching complete +transition: 'test_klp_syscall': initializing patching transition +transition: 'test_klp_syscall': starting patching transition +transition: 'test_klp_syscall': completing patching transition +transition: 'test_klp_syscall': patching complete test_klp_syscall: Remaining not livepatched processes: 0 % echo 0 > /sys/kernel/livepatch/test_klp_syscall/enabled -livepatch: 'test_klp_syscall': initializing unpatching transition -livepatch: 'test_klp_syscall': starting unpatching transition -livepatch: 'test_klp_syscall': completing unpatching transition -livepatch: 'test_klp_syscall': unpatching complete +transition: 'test_klp_syscall': initializing unpatching transition +transition: 'test_klp_syscall': starting unpatching transition +transition: 'test_klp_syscall': completing unpatching transition +transition: 'test_klp_syscall': unpatching complete % rmmod test_klp_syscall 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.
