[PATCH 1/1] epoll: call final ep_events_available() check under the lock

by Roman Penyaev

The original problem was described here: https://lkml.org/lkml/2020/4/27/1121 There is a possible race when ep_scan_ready_list() leaves ->rdllist and ->obflist empty for a short period of time although some events are pending. It is quite likely that ep_events_available() observes empty lists and goes to sleep. Since 339ddb53d373 ("fs/epoll: remove unnecessary wakeups of nested epoll") we are conservative in wakeups (there is only one place for wakeup and this is ep_poll_callback()), thus ep_events_available() must always observe correct state of two lists. The easiest and correct way is to do the final check under the lock. This does not impact the performance, since lock is taken anyway for adding a wait entry to the wait queue. In this patch barrierless __set_current_state() is used. This is safe since waitqueue_active() is called under the same lock on wakeup side. Short-circuit for fatal signals (i.e. fatal_signal_pending() check) is moved to the line just before actual events harvesting routine. This is fully compliant to what is said in the comment of the patch where the actual fatal_signal_pending() check was added: c257a340ede0 ("fs, epoll: short circuit fetching events if thread has been killed").

[withdrawn] epoll-ensure-ep_poll-doesnt-miss-wakeup-events.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: epoll: ensure ep_poll() doesn't miss wakeup events has been removed from the -mm tree. Its filename was epoll-ensure-ep_poll-doesnt-miss-wakeup-events.patch This patch was dropped because it was withdrawn ------------------------------------------------------ From: Jason Baron <jbaron(a)akamai.com> Subject: epoll: ensure ep_poll() doesn't miss wakeup events Now that the ep_events_available() check is done in a lockless way, and we no longer perform wakeups from ep_scan_ready_list(), we need to ensure that either ep->rdllist has items or the overflow list is active. Prior to: commit 339ddb53d373 ("fs/epoll: remove unnecessary wakeups of nested epoll"), we did wake_up(&ep->wq) after manipulating the ep->rdllist and the overflow list. Thus, any waiters would observe the correct state. However, with that wake_up() now removed we need to be more careful to ensure that condition. Here's an example of what could go wrong: We have epoll fds: epfd1, epfd2. And epfd1 is added to epfd2 and epfd2 is added to a socket: epfd1->epfd2->socket. Thread a is doing epoll_wait() on epfd1, and thread b is doing epoll_wait on epfd2. Then: 1) data comes in on socket ep_poll_callback() wakes up threads a and b 2) thread a runs ep_poll() ep_scan_ready_list() ep_send_events_proc() ep_item_poll() ep_scan_ready_list() list_splice_init(&ep->rdllist, &txlist); 3) now thread b is running ep_poll() ep_events_available() returns false schedule_hrtimeout_range() Thus, thread b has now scheduled and missed the wakeup.

The patch titled Subject: epoll: call final ep_events_available() check under the lock has been added to the -mm tree. Its filename is epoll-call-final-ep_events_available-check-under-the-lock.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/epoll-call-final-ep_events_availab… and later at http://ozlabs.org/~akpm/mmotm/broken-out/epoll-call-final-ep_events_availab… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Roman Penyaev <rpenyaev(a)suse.de> Subject: epoll: call final ep_events_available() check under the lock There is a possible race when ep_scan_ready_list() leaves ->rdllist and ->obflist empty for a short period of time although some events are pending. It is quite likely that ep_events_available() observes empty lists and goes to sleep. Since 339ddb53d373 ("fs/epoll: remove unnecessary wakeups of nested epoll") we are conservative in wakeups (there is only one place for wakeup and this is ep_poll_callback()), thus ep_events_available() must always observe correct state of two lists. The easiest and correct way is to do the final check under the lock. This does not impact the performance, since lock is taken anyway for adding a wait entry to the wait queue. The discussion of the problem can be found here: https://lore.kernel.org/linux-fsdevel/a2f22c3c-c25a-4bda-8339-a7bdaf17849e@… In this patch barrierless __set_current_state() is used. This is safe since waitqueue_active() is called under the same lock on wakeup side. Short-circuit for fatal signals (i.e. fatal_signal_pending() check) is moved to the line just before actual events harvesting routine. This is fully compliant to what is said in the comment of the patch where the actual fatal_signal_pending() check was added: c257a340ede0 ("fs, epoll: short circuit fetching events if thread has been killed").

[PATCH] drm: Fix HDCP failures when SRM fw is missing

by Sean Paul

From: Sean Paul <seanpaul(a)chromium.org> The SRM cleanup in 79643fddd6eb2 ("drm/hdcp: optimizing the srm handling") inadvertently altered the behavior of HDCP auth when the SRM firmware is missing. Before that patch, missing SRM was interpreted as the device having no revoked keys. With that patch, if the SRM fw file is missing we reject _all_ keys. This patch fixes that regression by returning success if the file cannot be found.
