selftests/pidfd: add pidfd setns tests

2020-05-13T09:41:22Z

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 Link: https://lore.kernel.org/r/20200505140432.181565-4-christian.brauner@ubuntu.com

test: Add test for pidfd getfd

2020-01-13T20:49:54Z

The following tests: * Fetch FD, and then compare via kcmp * Make sure getfd can be blocked by blocking ptrace_may_access * Making sure fetching bad FDs fails * Make sure trying to set flags to non-zero results in an EINVAL Signed-off-by: Sargun Dhillon Acked-by: Christian Brauner Link: https://lore.kernel.org/r/20200107175927.4558-5-sargun@sargun.me Signed-off-by: Christian Brauner

tests: add pidfd poll tests

2019-08-06T17:52:41Z

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 Link: https://lore.kernel.org/r/20190726162226.252750-2-surenb@google.com Signed-off-by: Christian Brauner

pidfd: add pidfd_wait tests

2019-08-06T17:39:30Z

Add tests for pidfd_wait() and CLONE_WAIT_PID: - test that waitid(P_PIDFD) fails on /proc/ - test that waitid(P_PIDFD) fails on /dev/null - test that waitid(P_PIDFD) can wait on a pidfd - test that waitid(P_PIDFD) can wait on a pidfd and return siginfo_t - test that waitid(P_PIDFD) works with WEXITED - test that waitid(P_PIDFD) works with WSTOPPED - test that waitid(P_PIDFD) works with WUNTRACED - test that waitid(P_PIDFD) works with WCONTINUED - test that waitid(P_PIDFD) works with WNOWAIT - test that waitid(P_PIDFD)works with WNOHANG Signed-off-by: Christian Brauner Reviewed-by: Kees Cook Cc: Arnd Bergmann Cc: "Eric W.

tests: add pidfd_open() tests

2019-06-28T10:17:55Z

This adds testing for the new pidfd_open() syscalls. Specifically, we test: - that no invalid flags can be passed to pidfd_open() - that no invalid pid can be passed to pidfd_open() - that a pidfd can be retrieved with pidfd_open() - that the retrieved pidfd references the correct pid Signed-off-by: Christian Brauner Cc: Arnd Bergmann Cc: "Eric W.
