So by checking the state you were waiting for, and then # adding yourself to the wait queue before dropping the lock, you were # guaranteed to see all the wakeups. # # Strictly speaking, the actual wakeups were not done under the lock, but # the pipe_wait() model still worked, because since the waiter held the # lock when checking whether it should sleep, it would always see the # current state, and the wakeup was always done after updating the state. # # However, commit 0ddad21d3e99 ("pipe: use exclusive waits when reading or # writing") split the single wait-queue into two, and in the process also # made the "wait for event" code wait for _two_ wait queues, and that then # showed a race with the wakers that were not serialized by the pipe lock. # # It's only splice that used that "pipe_wait()" model, so the problem # wasn't obvious, but Josef Bacik reports: # # "I hit a hang with fstest btrfs/187, which does a btrfs send into # /dev/null. This works by creating a pipe, the write side is given to # the kernel to write into, and the read side is handed to a thread that # splices into a file, in this case /dev/null. # # The box that was hung had the write side stuck here [pipe_write] and # the read side stuck here [splice_from_pipe_next -> pipe_wait]. # # [ more details about pipe_wait() scenario ] # # The problem is we're doing the prepare_to_wait, which sets our state # each time, however we can be woken up either with reads or writes. In # the case above we race with the WRITER waking us up, and re-set our # state to INTERRUPTIBLE, and thus never break out of schedule" # # Josef had a patch that avoided the issue in pipe_wait() by just making # it set the state only once, but the deeper problem is that pipe_wait() # depends on a level of synchonization by the pipe mutex that it really # shouldn't. And the whole "wait for any pipe state change" model really # isn't very good to begin with. # # So rather than trying to work around things in pipe_wait(), remove that # legacy model of "wait for arbitrary pipe event" entirely, and actually # create functions that wait for the pipe actually being readable or # writable, and can do so without depending on the pipe lock serializing # everything.
