Fix a couple of issues at tools/testing/selftests/bpf/Makefile so the following command make -C tools/testing/selftests/bpf OUTPUT=/home/yhs/tmp can put the built results into a different directory. Also add the built binary test_tcpbpf_user in the .gitignore file. Fixes: 6882804c ("selftests/bpf: add a test for overlapping packet range checks") Fixes: 9d1f1594 ("bpf: move cgroup_helpers from samples/bpf/ to tools/testing/selftesting/bpf/") Signed-off-by: NYonghong Song <yhs@fb.com> Signed-off-by: NDaniel Borkmann <daniel@iogearbox.net>

We were calculating the delta from a in-flight syscall that got its output interrupted by another syscall, which doesn't seem like useful information, we will print the syscall duration (sys_exit - sys_enter) when the raw_syscalls:sys_exit event happens. The problem here is how we're consuming the multiple ring buffers, without using the ordered_events code used by perf_session, which may cause some reordering of syscalls for diferent CPUs, so just stop printing that delta, to avoid things like: # trace --print-sample -p 9626 -e futex raw_syscalls:sys_enter 411967179.269 Timer 9609/9626 [2] raw_syscalls:sys_enter 411967179.213 file:// Content 9609/9609 [3] 328.038 (18446744073709.496 ms): Timer/9626 futex(uaddr: 0x7fc0d4027044, op: WAIT|PRIV, utime: 0x7fc0b0ffdb50 ) ... raw_syscalls:sys_exit 411967179.225 file:// Content 9609/9609 [3] 327.982 ( 0.012 ms): file:// Conten/9609 futex(uaddr: 0x7fc0d4027040, op: WAKE|PRIV, val: 1 ) = 1 This is a bandaid, we should better try and use the ordered_events code, possibly with some refactoring prep work, but for now at least we don't show those false long deltas for the lines ending in '...'.
