2019-08-19liburing/barrier.h: Add prefix io_uring to barriersJulia Suvorova
The names of the barriers conflict with the namespaces of other projects when trying to directly include liburing.h. Avoid using popular global names. Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Julia Suvorova <jusual@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-07-24src/Makefile: keep private headers in <liburing/*.h>Stefan Hajnoczi
It is not possible to install barrier.h and compat.h into the top-level /usr/include directly since they are likely to conflict with other software. io_uring.h could be confused with the system's kernel header file. Put liburing headers into <liburing/*.h> so there is no chance of conflicts or confusion. Existing applications continue to build successfully since the location of <liburing.h> is unchanged. In-tree examples and tests require modification because src/liburing.h is moved to src/include/liburing.h.

2019-07-08Fix the 32-bit buildBart Van Assche
Fix the warnings reported when building liburing as follows: make CFLAGS=-m32 Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-07-08Makefiles: Support specifying CFLAGS on the command lineBart Van Assche
This patch makes the liburing build work as expected for e.g. the following command: make CFLAGS=-m32 and avoids that the build fails as follows for the above command: make[1]: Entering directory 'liburing/test' cc -m32 -o poll poll.c -luring /usr/bin/ld: cannot find -luring collect2: error: ld returned 1 exit status Makefile:18: recipe for target 'poll' failed make[1]: *** [poll] Error 1 make[1]: Leaving directory 'software/liburing/test' Makefile:12: recipe for target 'all' failed make: *** [all] Error 2 Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-07-02Fix the use of memory barriersBart Van Assche
Introduce the smp_load_acquire() and smp_store_release() macros. Fix synchronization in io_uring_cq_advance() and __io_uring_get_cqe(). Remove a superfluous local variable, if-test and write barrier from __io_uring_submit(). Remove a superfluous barrier from test/io_uring_enter.c.

2019-06-04test/ring-leak: use static array for io_uring_register()Jens Axboe
Don't leak the memory. We never need to reference it from the test app once the io_uring_register() call is done. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2019-05-14test/io_uring_register: don't fail max fd test if we run out of memJens Axboe
We need a lot of RAM for this case, my vm always fails it. Don't hard fail due to ENOMEM, just skip the test. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2019-05-01test/io_uring_setup: don't fail SQPOLL test case for non-rootJens Axboe
SQPOLL requires root, if the tests are run as a user, we'll get EPERM instead of EINVAL. Don't fail the test because of that, just mention it in the log. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2019-05-01liburing: improve output for test/io_uring_setup.cShenghui Wang
For the IORING_SETUP_SQPOLL|IORING_SETUP_SQ_AFF test case, add_pipe is not set, and the output is like: "...flags: IORING_SETUP_SQPOLLIORING_SETUP_SQ_AFF...". Set add_pipe for IORING_SETUP_SQPOLL flag so that the output is like: "...flags: IORING_SETUP_SQPOLL|IORING_SETUP_SQ_AFF...".

2019-04-18Rename completion helpersJens Axboe
We have io_uring_get_sqe() on the submission side, yet the completion side is named _completion. Rename as follows: io_uring_get_completion() io_uring_peek_cqe() iO_uring_wait_completion() io_uring_wait_cqe() This better tells the user what the _get variant does by calling it _peek instead, and we move to using _cqe() as the postfix instead of _completion. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-04-17Separate test cases from examplesJens Axboe
Also adds a runtests makefile target.
2019-04-17Add io_uring_cqe_seen()Jens Axboe
There's a failure case where an application gets a cqe entry, but the kernel can then overwrite it before the application is done reading it. This can happen since the io_uring_{get,wait}_completion() interface both returns a CQE pointer AND increments the ring index. If the kernel reuses this entry before the applications is done reading it, the contents may be corrupted. Remove the CQ head increment from the CQE retrieval, and put it into a separate helper, io_uring_cqe_seen(). The application must call this helper when it got a new CQE entry through one of the above calls, and it's now done reading it. Signed-off-by: Jens Axboe <axboe@kernel.dk>

The parent may well die before the child is done, as long as it wrote to the pipe, we're fine. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-18test/poll: simply test caseJens Axboe
Just setup one ring in the child process, and poll for when the read side of the pipe is readable. From the parent, write something to the pipe. If nothing happens within 1 second, fail the test. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-01-18test/poll-cancel: improve test caseJens Axboe
- Add a timeout, if we don't finish in one second we are definitely hung because the poll remove command didn't work. - Don't assume completion ordering Signed-off-by: Jens Axboe <axboe@kernel.dk>
