2020-05-30io_uring: fix overflowed reqs cancellationPavel Begunkov1-2/+3
Overflowed requests in io_uring_cancel_files() should be shed only of inflight and overflowed refs. All other left references are owned by someone else. If refcount_sub_and_test() fails, it will go further and put put extra ref, don't do that. Also, don't need to do io_wq_cancel_work() for overflowed reqs, they will be let go shortly anyway.

2020-05-30io_uring: off timeouts based only on completionsPavel Begunkov1-51/+14

2020-05-26io_uring: get rid of manual punting in io_closePavel Begunkov1-15/+5

2020-05-26io_uring: separate DRAIN flushing into a cold pathPavel Begunkov1-15/+15
io_commit_cqring() assembly doesn't look good with extra code handling drained requests. IOSQE_IO_DRAIN is slow and discouraged to be used in a hot path, so try to minimise its impact by putting it into a helper and doing a fast check.

2020-05-26io_uring: fix flush req->refs underflowPavel Begunkov1-1/+1
In io_uring_cancel_files(), after refcount_sub_and_test() leaves 0 req->refs, it calls io_put_req(), which would also put a ref. Call io_free_req() instead.

2020-05-20io_uring: don't submit sqes when ctx->refs is dyingXiaoguang Wang1-11/+2
When IORING_SETUP_SQPOLL is enabled, io_ring_ctx_wait_and_kill() will wait for sq thread to idle by busy loop: while (ctx->sqo_thread && !wq_has_sleeper(&ctx->sqo_wait)) cond_resched(); Above loop isn't very CPU friendly, it may introduce a short cpu burst on the current cpu. If ctx->refs is dying, we forbid sq_thread from submitting any further SQEs. Instead they just get discarded when we exit.

2020-05-17io_uring: async task poll trigger cleanupJens Axboe1-17/+16

2020-05-17io_uring: rename io_file_put()Pavel Begunkov1-9/+13
io_file_put() deals with flushing state's file refs, adding "state" to its name makes it a bit clearer. Also, avoid double check of state->file in __io_file_get() in some cases. Signed-off-by: Pavel Begunkov <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2020-05-17io_uring: remove req->needs_fixed_filesPavel Begunkov1-9/+12

2020-05-17io_uring: cleanup io_poll_remove_one() logicJens Axboe1-14/+13
We only need apoll in the one section, do the juggling with the work restoration there. This removes a special case further down as well. No functional changes in this patch. Signed-off-by: Jens Axboe <[email protected]>
2020-05-15io_uring: file registration list and lock optimizationJens Axboe1-14/+10
There's no point in using list_del_init() on entries that are going away, and the associated lock is always used in process context so let's not use the IRQ disabling+saving variant of the spinlock. Signed-off-by: Jens Axboe <[email protected]>
2020-05-15io_uring: add IORING_CQ_EVENTFD_DISABLED to the CQ ring flagsStefano Garzarella2-0/+9
This new flag should be set/clear from the application to disable/enable eventfd notifications when a request is completed and queued to the CQ ring. Before this patch, notifications were always sent if an eventfd is registered, so IORING_CQ_EVENTFD_DISABLED is not set during the initialization. It will be up to the application to set the flag after initialization if no notifications are required at the beginning. Signed-off-by: Stefano Garzarella <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2020-05-15io_uring: add 'cq_flags' field for the CQ ringStefano Garzarella2-2/+12
This patch adds the new 'cq_flags' field that should be written by the application and read by the kernel. This new field is available to the userspace application through 'cq_off.flags'. We are using 4-bytes previously reserved and set to zero. This means that if the application finds this field to zero, then the new functionality is not supported. In the next patch we will introduce the first flag available. Signed-off-by: Stefano Garzarella <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2020-05-15io_uring: allow POLL_ADD with double poll_wait() usersJens Axboe1-72/+146
Some file descriptors use separate waitqueues for their f_ops->poll() handler, most commonly one for read and one for write. The io_uring poll implementation doesn't work with that, as the 2nd poll_wait() call will cause the io_uring poll request to -EINVAL. This affects (at least) tty devices and /dev/random as well. This is a big problem for event loops where some file descriptors work, and others don't. With this fix, io_uring handles multiple waitqueues. Signed-off-by: Jens Axboe <[email protected]>
2020-05-15io_uring: batch reap of dead file registrationsJens Axboe1-12/+42
We currently embed and queue a work item per fixed_file_ref_node that we update, but if the workload does a lot of these, then the associated kworker-events overhead can become quite noticeable. Since we rarely need to wait on these, batch them at 1 second intervals instead. If we do need to wait for them, we just flush the pending delayed work. Signed-off-by: Jens Axboe <[email protected]>
2020-05-14io_uring: name sq thread and ref completionsJens Axboe1-16/+10
We used to have three completions, now we just have two. With the two, let's not allocate them dynamically, just embed then in the ctx and name them appropriately. Signed-off-by: Jens Axboe <[email protected]>

2020-05-08io_uring: remove 'fd is io_uring' from close pathJens Axboe1-6/+4
The attempt protecting us from closing the ring itself wasn't really complete, and we actually don't need it. The referencing of requests themselve, and the references they hold on the ring, ensures that the life time of the ring is sane. With the check removed, we can also remove the need to have the close operation fget() the file. Reported-by: Al Viro <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2020-05-07io_uring: don't use 'fd' for openat/openat2/statxJens Axboe1-25/+7
We currently make some guesses as when to open this fd, but in reality we have no business (or need) to do so at all. In fact, it makes certain things fail, like O_PATH. Remove the fd lookup from these opcodes, we're just passing the 'fd' to generic helpers anyway. With that, we can also remove the special casing of fd values in io_req_needs_file(), and the 'fd_non_neg' check that we have. And we can ensure that we only read sqe->fd once. This fixes O_PATH usage with openat/openat2, and ditto statx path side oddities.

2020-05-05io_uring: handle -EFAULT properly in io_uring_setup()Xiaoguang Wang1-13/+11
If copy_to_user() in io_uring_setup() failed, we'll leak many kernel resources, which will be recycled until process terminates. This bug can be reproduced by using mprotect to set params to PROT_READ. To fix this issue, refactor io_uring_create() a bit to add a new 'struct io_uring_params __user *params' parameter and move the copy_to_user() in io_uring_setup() to io_uring_setup(), if copy_to_user() failed, we can free kernel resource properly.
