2019-07-30selftests/bpf: fix clearing buffered output between tests/subtestsAndrii Nakryiko
Clear buffered output once test or subtests finishes even if test was successful. Not doing this leads to accumulation of output from previous tests and on first failed tests lots of irrelevant output will be dumped, greatly confusing things. v1->v2: fix Fixes tag, add more context to patch Fixes: 3a516a0a3a7b ("selftests/bpf: add sub-tests support for test_progs") Signed-off-by: Andrii Nakryiko <andriin@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2019-07-30selftests/bpf: add test for bpf_tcp_gen_syncookiePetar Penkov
Modify the existing bpf_tcp_check_syncookie test to also generate a SYN cookie, pass the packet to the kernel, and verify that the two cookies are the same (and both valid). Since cloned SKBs are skipped during generic XDP, this test does not issue a SYN cookie when run in XDP mode. We therefore only check that a valid SYN cookie was issued at the TC hook. Additionally, verify that the MSS for that SYN cookie is within expected range.

2019-07-30selftests/livepatch: push and pop dynamic debug configJoe Lawrence
The livepatching self-tests tweak the dynamic debug config to verify the kernel log during the tests. Enhance set_dynamic_debug() so that the config changes are restored when the script exits. Note this functionality needs to keep in sync with: - dynamic_debug input/output formatting - functions affected by set_dynamic_debug() For example, push_dynamic_debug() transforms: kernel/livepatch/transition.c:530 [livepatch]klp_init_transition =_ "'%s': initializing %s transition\012" to the following: file kernel/livepatch/transition.c line 530 =_ Signed-off-by: Joe Lawrence <joe.lawrence@redhat.com> Tested-by: Petr Mladek <pmladek@suse.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2019-07-30kselftest: save-and-restore errno to allow for %m formattingAleksa Sarai
Previously, using "%m" in a ksft_* format string can result in strange output because the errno value wasn't saved before calling other libc functions. The solution is to simply save and restore the errno before we format the user-supplied format string.
