Problem on ppc64le continues (currently on stable kernel 5.10.16), but also for some time reproducible on x86_64. I'm now able to reproduce the problem on x86_64 as well (5.12.0-rc1-2.g4b1061b-default): # ./klp_tc_10.sh [12:41:51] Test Case 10: Patch caller of graph traced callee [12:41:51] *** Compiling kernel live patch [12:41:51] make: Entering directory '/usr/src/linux-5.12.0-rc1-2.g4b1061b-obj/x86_64/default' [12:41:52] CC [M] /tmp/live-patch/tc_10/klp_tc_10_livepatch.o [12:41:52] MODPOST /tmp/live-patch/tc_10/Module.symvers [12:41:52] CC [M] /tmp/live-patch/tc_10/klp_tc_10_livepatch.mod.o [12:41:52] LD [M] /tmp/live-patch/tc_10/klp_tc_10_livepatch.ko [12:41:52] BTF [M] /tmp/live-patch/tc_10/klp_tc_10_livepatch.ko [12:41:52] Skipping BTF generation for /tmp/live-patch/tc_10/klp_tc_10_livepatch.ko due to unavailability of vmlinux [12:41:52] make: Leaving directory '/usr/src/linux-5.12.0-rc1-2.g4b1061b-obj/x86_64/default' [12:41:52] *** Compile test support module [12:41:53] make: Entering directory '/usr/src/linux-5.12.0-rc1-2.g4b1061b-obj/x86_64/default' [12:41:53] CC [M] /tmp/live-patch/tc_10/klp_test_support_mod.o [12:41:54] MODPOST /tmp/live-patch/tc_10/Module.symvers [12:41:54] CC [M] /tmp/live-patch/tc_10/klp_test_support_mod.mod.o [12:41:54] LD [M] /tmp/live-patch/tc_10/klp_test_support_mod.ko [12:41:54] BTF [M] /tmp/live-patch/tc_10/klp_test_support_mod.ko [12:41:54] Skipping BTF generation for /tmp/live-patch/tc_10/klp_test_support_mod.ko due to unavailability of vmlinux [12:41:54] make: Leaving directory '/usr/src/linux-5.12.0-rc1-2.g4b1061b-obj/x86_64/default' [12:41:54] *** Load test support module [12:41:54] *** Enable graph tracing for orig_do_sleep [12:41:55] ./klp_tc_10.sh: line 36: echo: write error: Invalid argument [12:41:55] TEST FAILED while executing 'echo "orig_do_sleep" > /sys/kernel/debug/tracing/set_ftrace_filter', EXITING
