tests: add pidfd_open() tests 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 <christian@brauner.io> Cc: Arnd Bergmann <arnd@arndb.de> Cc: "Eric W.

selftests/pidfd: add pidfd setns tests 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 2020-05-05 21:04:32 +07:00			`TEST_GEN_PROGS := pidfd_test pidfd_fdinfo_test pidfd_open_test \`
