selftests/binderfs: Fix harness API usage

2020-07-06T21:59:16+00:00

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. Acked-by: Christian Brauner Signed-off-by: Kees Cook Signed-off-by: Shuah Khan

kselftests: introduce new epoll60 testcase for catching lost wakeups

2020-05-08T02:27:21+00:00

This test case catches lost wake up introduced by commit 339ddb53d373 ("fs/epoll: remove unnecessary wakeups of nested epoll") The test is simple: we have 10 threads and 10 event fds. Each thread can harvest only 1 event. 1 producer fires all 10 events at once and waits that all 10 events will be observed by 10 threads. In case of lost wakeup epoll_wait() will timeout and 0 will be returned. Test case catches two sort of problems: forgotten wakeup on event, which hits the ->ovflist list, this problem was fixed by: 5a2513239750 ("eventpoll: fix missing wakeup for ovflist in ep_poll_callback") the other problem is when several sequential events hit the same waiting thread, thus other waiters get no wakeups. Problem is fixed in the following patch.

kselftest: introduce new epoll test case

2020-04-07T17:43:44+00:00

This testcase repeats epollbug.c from the bug: https://bugzilla.kernel.org/show_bug.cgi?id=205933 What it tests? It tests the race between epoll_ctl() and epoll_wait(). New event mask passed to epoll_ctl() triggers wake up, which can be missed because of the bug described in the link. Reproduction is 100%, so easy to fix. Kudos, Max, for wonderful test case.
