2019-12-23rseq/selftests: Clarify rseq_prepare_unload() helper requirementsMathieu Desnoyers
The rseq.h UAPI now documents that the rseq_cs field must be cleared before reclaiming memory that contains the targeted struct rseq_cs, but also that the rseq_cs field must be cleared before reclaiming memory of the code pointed to by the rseq_cs start_ip and post_commit_offset fields. While we can expect that use of dlclose(3) will typically unmap both struct rseq_cs and its associated code at once, nothing would theoretically prevent a JIT from reclaiming the code without reclaiming the struct rseq_cs, which would erroneously allow the kernel to consider new code which is not a rseq critical section as a rseq critical section following a code reclaim.

2019-12-23rseq/selftests: Fix: Namespace gettid() for compatibility with glibc 2.30Mathieu Desnoyers
glibc 2.30 introduces gettid() in public headers, which clashes with the internal static definition within rseq selftests. Rename gettid() to rseq_gettid() to eliminate this symbol name clash.

2019-12-09selftests/ftrace: Fix multiple kprobe testcaseMasami Hiramatsu
Fix multiple kprobe event testcase to work it correctly. There are 2 bugfixes. - Since `wc -l FILE` returns not only line number but also FILE filename, following "if" statement always failed. Fix this bug by replacing it with 'cat FILE | wc -l' - Since "while do-done loop" block with pipeline becomes a subshell, $N local variable is not update outside of the loop. Fix this bug by using actual target number (256) instead of $N.

2019-12-09selftests/ftrace: Do not to use absolute debugfs pathMasami Hiramatsu
Use relative path to trigger file instead of absolute debugfs path, because if the user uses tracefs instead of debugfs, it can be mounted at /sys/kernel/tracing. Anyway, since the ftracetest is designed to be run at the tracing directory, user doesn't need to use absolute path.

2019-12-09selftests/ftrace: Fix ftrace test cases to check unsupportedMasami Hiramatsu
Since dynamic function tracer can be disabled, set_ftrace_filter can be disappeared. Test cases which depends on it, must check whether the set_ftrace_filter exists or not before testing and if not, return as unsupported. Also, if the function tracer itself is disabled, we can not set "function" to current_tracer. Test cases must check it before testing, and return as unsupported.

2019-12-09selftests/ftrace: Fix to check the existence of set_ftrace_filterMasami Hiramatsu
If we run ftracetest on the kernel with CONFIG_DYNAMIC_FTRACE=n, there is no set_ftrace_filter and all test cases are failed, because reset_ftrace_filter() returns an error. Let's check whether set_ftrace_filter exists in reset_ftrace_filter() and clean up only set_ftrace_notrace in initialize_ftrace().

2019-12-04selftests/bpf: De-flake test_tcpbpfStanislav Fomichev
It looks like BPF program that handles BPF_SOCK_OPS_STATE_CB state can race with the bpf_map_lookup_elem("global_map"); I sometimes see the failures in this test and re-running helps. Since we know that we expect the callback to be called 3 times (one time for listener socket, two times for both ends of the connection), let's export this number and add simple retry logic around that. Also, let's make EXPECT_EQ() not return on failure, but continue evaluating all conditions; that should make potential debugging easier. With this fix in place I don't observe the flakiness anymore.
