2023-07-26selftests: mptcp: join: only check for ip6tables if neededMatthieu Baerts
If 'iptables-legacy' is available, 'ip6tables-legacy' command will be used instead of 'ip6tables'. So no need to look if 'ip6tables' is available in this case.

2023-07-20perf trace: Really free the evsel->priv areaArnaldo Carvalho de Melo
In 3cb4d5e00e037c70 ("perf trace: Free syscall tp fields in evsel->priv") it only was freeing if strcmp(evsel->tp_format->system, "syscalls") returned zero, while the corresponding initialization of evsel->priv was being performed if it was _not_ zero, i.e. if the tp system wasn't 'syscalls'. Just stop looking for that and free it if evsel->priv was set, which should be equivalent. Also use the pre-existing evsel_trace__delete() function.

2023-07-18selftests: tc: set timeout to 15 minutesMatthieu Baerts
When looking for something else in LKFT reports [1], I noticed that the TC selftest ended with a timeout error: not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds The timeout had been introduced 3 years ago, see the Fixes commit below. This timeout is only in place when executing the selftests via the kselftests runner scripts. I guess this is not what most TC devs are using and nobody noticed the issue before. The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks like it is plenty more time than what it takes in "normal" conditions.

2023-07-17perf test task_exit: No need for a cycles event to check if we get an ↵Arnaldo Carvalho de Melo
PERF_RECORD_EXIT The intent of this test is to check we get a PERF_RECORD_EXIT as asked for by setting perf_event_attr.task=1. When the test was written we didn't had the "dummy" event so we went with the default event, "cycles". There were reports of this test failing sometimes, one of these reports was with a PREEMPT_RT_FULL, but I noticed it failing sometimes with an aarch64 Firefly board. In the kernel the call to perf_event_task_output(), that generates the PERF_RECORD_EXIT may fail when there is not enough memory in the ring buffer, if the ring buffer is paused, etc. So switch to using the "dummy" event to use the ring buffer just for what the test was designed for, avoiding uneeded PERF_RECORD_SAMPLEs.

2023-07-14selftests/arm64: fix build failure during the "emit_tests" stepJohn Hubbard
The build failure reported in [1] occurred because commit <9fc96c7c19df> ("selftests: error out if kernel header files are not yet built") added a new "kernel_header_files" dependency to "all", and that triggered another, pre-existing problem. Specifically, the arm64 selftests override the emit_tests target, and that override improperly declares itself to depend upon the "all" target. This is a problem because the "emit_tests" target in lib.mk was not intended to be overridden. emit_tests is a very simple, sequential build target that was originally invoked from the "install" target, which in turn, depends upon "all". That approach worked for years. But with 9fc96c7c19df in place, emit_tests failed, because it does not set up all of the elaborate things that "install" does. And that caused the new "kernel_header_files" target (which depends upon $(KBUILD_OUTPUT) being correct) to fail. Some detail: The "all" target is .PHONY. Therefore, each target that depends on "all" will cause it to be invoked again, and because dependencies are managed quite loosely in the selftests Makefiles, many things will run, even "all" is invoked several times in immediate succession. So this is not a "real" failure, as far as build steps go: everything gets built, but "all" reports a problem when invoked a second time from a bad environment. To fix this, simply remove the unnecessary "all" dependency from the overridden emit_tests target. The dependency is still effectively honored, because again, invocation is via "install", which also depends upon "all". An alternative approach would be to harden the emit_tests target so that it can depend upon "all", but that's a lot more complicated and hard to get right, and doesn't seem worth it, especially given that emit_tests should probably not be overridden at all.

2023-07-14selftests/riscv: fix potential build failure during the "emit_tests" stepJohn Hubbard
The riscv selftests (which were modeled after the arm64 selftests) are improperly declaring the "emit_tests" target to depend upon the "all" target. This approach, when combined with commit 9fc96c7c19df ("selftests: error out if kernel header files are not yet built"), has caused build failures [1] on arm64, and is likely to cause similar failures for riscv. To fix this, simply remove the unnecessary "all" dependency from the emit_tests target. The dependency is still effectively honored, because again, invocation is via "install", which also depends upon "all". An alternative approach would be to harden the emit_tests target so that it can depend upon "all", but that's a lot more complicated and hard to get right, and doesn't seem worth it, especially given that emit_tests should probably not be overridden at all.
