2020-05-13selftests/pidfd: add pidfd setns testsChristian Brauner
This is basically a test-suite for setns() and as of now contains: - test that we can't pass garbage flags - test that we can't attach to the namespaces of task that has already exited - test that we can incrementally setns into all namespaces of a target task using a pidfd - test that we can setns atomically into all namespaces of a target task - test that we can't cross setns into a user namespace outside of our user namespace hierarchy - test that we can't setns into namespaces owned by user namespaces over which we are not privileged Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com> Link: https://lore.kernel.org/r/20200505140432.181565-4-christian.brauner@ubuntu.com

2019-08-06tests: add pidfd poll testsSuren Baghdasaryan
This adds testing for polling on pidfd of a process being killed. Test runs 10000 iterations by default to stress test pidfd polling functionality. It accepts an optional command-line parameter to override the number or iterations to run. Specifically, it tests for: - pidfd_open on a child process succeeds - pidfd_send_signal on a child process succeeds - polling on pidfd succeeds and returns exactly one event - returned event is POLLIN - event is received within 3 secs of the process being killed 10000 iterations was chosen because of the race condition being tested which is not consistently reproducible but usually is revealed after less than 2000 iterations. Reveals race fixed by commit b191d6491be6 ("pidfd: fix a poll race when setting exit_state") Signed-off-by: Suren Baghdasaryan <surenb@google.com> Link: https://lore.kernel.org/r/20190726162226.252750-2-surenb@google.com Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com>
