2020-11-05selftests: binderfs: use SKIP instead of XFAILTommi Rantala1-4/+4
XFAIL is gone since commit 9847d24af95c ("selftests/harness: Refactor XFAIL into SKIP"), use SKIP instead.

2020-07-06selftests/binderfs: Fix harness API usageKees Cook1-138/+146
The binderfs test mixed the full harness API and the selftest API. Adjust to use only the harness API so that the harness API can switch to using the selftest API internally in future patches.

2020-03-19binderfs: add stress test for binderfs binder devicesChristian Brauner1-93/+333
This adds a stress test that should hopefully help us catch regressions for [1], [2], and [3]. [1]: 2669b8b0c798 ("binder: prevent UAF for binderfs devices") [2]: f0fe2c0f050d ("binder: prevent UAF for binderfs devices II") [3]: 211b64e4b5b6 ("binderfs: use refcount for binder control devices too") Signed-off-by: Christian Brauner <[email protected]> Reviewed-by: Kees Cook <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2020-03-19binderfs_test: switch from /dev to a unique per-test mountpointChristian Brauner1-24/+23
Unprivileged users will be able to create directories in there. The unprivileged test for /dev wouldn't have worked on most systems.

2019-01-30selftests: add binderfs selftestsChristian Brauner1-0/+275
This adds the promised selftest for binderfs. It will verify the following things: - binderfs mounting works - binder device allocation works - performing a binder ioctl() request through a binderfs device works - binder device removal works - binder-control removal fails - binderfs unmounting works The tests are performed both privileged and unprivileged. The latter verifies that binderfs behaves correctly in user namespaces.
