Alexei Starovoitov 075cd19188 selftests/bpf: Fix failure paths in send_signal test ... [ Upstream commit c133390398 ] When test_send_signal_kern__open_and_load() fails parent closes the pipe which cases ASSERT_EQ(read(pipe_p2c...)) to fail, but child continues and enters infinite loop, while parent is stuck in wait(NULL). Other error paths have similar issue, so kill the child before waiting on it. The bug was discovered while compiling all of selftests with -O1 instead of -O2 which caused progs/test_send_signal_kern.c to fail to load.
