2018-05-30selftests: net: return Kselftest Skip code for skipped testsShuah Khan (Samsung OSG)5-25/+39
When net test is skipped because of unmet dependencies and/or unsupported configuration, it returns 0 which is treated as a pass by the Kselftest framework. This leads to false positive result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped. Change psock_tpacket to use ksft_exit_skip() when a non-root user runs the test and add an explicit check for root and a clear message, instead of failing the test when /sys/power/state file open fails.

2018-05-25Merge git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpfDavid S. Miller1-1/+3
Daniel Borkmann says: ==================== pull-request: bpf 2018-05-24 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Fix a bug in the original fix to prevent out of bounds speculation when multiple tail call maps from different branches or calls end up at the same tail call helper invocation, from Daniel. 2) Two selftest fixes, one in reuseport_bpf_numa where test is skipped in case of missing numa support and another one to update kernel config to properly support xdp_meta.sh test, from Anders. ... Would be great if you have a chance to merge net into net-next after that. The verifier fix would be needed later as a dependency in bpf-next for upcomig work there. When you do the merge there's a trivial conflict on BPF side with 849fa50662fb ("bpf/verifier: refine retval R0 state for bpf_get_stack helper"): Resolution is to keep both functions, the do_refine_retval_range() and record_func_map(). ==================== Signed-off-by: David S.

2018-03-17selftests: pmtu: Introduce support for multiple testsStefano Brivio1-26/+61
Introduce list of tests and their descriptions, and loop on it in main body. Tests will now just take care of calling setup with a list of "units" they need, and return 0 on success, 1 on failure, 2 if the test had to be skipped. Main script body will take care of displaying results and cleaning up after every test. Introduce guard variable so that we don't clean up twice in case of interrupts or unexpected failures. The pmtu_vti6_exception test can now run its third step even if the previous one failed, as we can return values from it. Also introduce support to display test descriptions, and display aligned OK/FAIL/SKIP test outcomes. Buffer error strings so that in case of failure we can display them right under the outcome for each test. Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Signed-off-by: David S.
