* harness: add test for aio poll missed eventsEric Biggers2022-03-251-0/+255
| | | | | | | | | | | Add a regression test for a recently-fixed kernel bug where aio polls sometimes didn't complete even if the file is ready. This is a cleaned-up version of the test which I originally posted at https://lore.kernel.org/r/YbMKtAjSJdXNTzOk@sol.localdomain Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Jeff Moyer <jmoyer@redhat.com>

* Fix test issue with gcc-11Lee Duncan2021-02-151-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Test 3.t exercises io_submit() with invalid addresses, and one test attempted to pass in "-1" as an invalid pointer. But gcc-11 realizes you cannot take an offset from an invalid pointer, making it impossible to compile or run this test: > sh# make CC=gcc-11 partcheck > make[1]: Entering directory '/alt/public_software/libaio/src' > make[1]: Nothing to be done for 'all'. > make[1]: Leaving directory '/alt/public_software/libaio/src' > make[1]: Entering directory '/alt/public_software/libaio/harness' > gcc-11 -Wall -Werror -I../src -g -O2 -DTEST_NAME=\"cases/2.t\" -o cases/2.p main.c ../src/libaio.a -lpthread > gcc-11 -Wall -Werror -I../src -g -O2 -DTEST_NAME=\"cases/3.t\" -o cases/3.p main.c ../src/libaio.a -lpthread > In file included from main.c:24: > cases/3.t: In function ‘test_main’: > cases/3.t:18:19: error: ‘attempt_io_submit’ accessing 8 bytes in a region of size 0 [-Werror=stringop-overflow=] > 18 | status |= attempt_io_submit( io_ctx, 1, (void *)-1, -EFAULT); > | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > cases/3.t:18:19: note: referencing argument 3 of type ‘struct iocb **’ > In file included from cases/3.t:5, > from main.c:24: > cases/aio_setup.h:15:5: note: in a call to function ‘attempt_io_submit’ > 15 | int attempt_io_submit(io_context_t ctx, long nr, struct iocb *ios[], int expect) > | ^~~~~~~~~~~~~~~~~ > cc1: all warnings being treated as errors > make[1]: *** [Makefile:19: cases/3.p] Error 1 > make[1]: Leaving directory '/alt/public_software/libaio/harness' > make: *** [Makefile:23: partcheck] Error 2 The fix is to tell gcc to relax it's stringop overflow testing for this one test.

* harness: Skip the test if io_pgetevents() is not implementedGuillem Jover2019-08-221-0/+7
| | | | | | | | | | | | Either the kernel or the syscall wrapper will return -ENOSYS when this syscall is not implemented. So we should cope with this in the test suite and SKIP the test case. This is currently the case for alpha and ia64, even though they have already been wired up very recently in the kernel mainline.

* harness: Print better error messages on error conditions in 22.tGuillem Jover2019-08-221-6/+9
| | | | | | | | | | These should help diagnose problems when dealing with error failures. In particular this helped distinguish the problem with io_pgetevents() not being implemented and it failing due to the sigset_t layout bug.

* harness: Fix PROT_WRITE mmap checkGuillem Jover2019-08-141-5/+4
| | | | | | | | | | | | | | | This partially reverts commit d7f5065448efb49b2a26e728ff735e12ea05b62e. The actual problem in the original code was that read() was being used to assert whether the buffer was readable, but the kernel was instead reading from the file descriptor and then writing into the buffer, so no EFAULT was being generated (on architectures that do so). We needed to use a write() so that the kernel would read from the buffer. Signed-off-by: Guillem Jover <guillem@hadrons.org> Signed-off-by: Jeff Moyer <jmoyer@redhat.com>
* harness: fix read into PROT_WRITE mmap testJeff Moyer2019-08-131-3/+3
| | | | | | | | | This test has been broken forever. Fix it up to perform an aio_read using the result of a regular read as the expected return code. Reported-by: Guillem Jover <guillem@hadrons.org> Signed-off-by: Jeff Moyer <jmoyer@redhat.com>
* harness: skip 22.p if async_poll isn't supportedJeff Moyer2019-07-291-1/+13
| | | | | | | Use the new skip error code instead of failing the test. Also add in a Local variables: section for emacs. Signed-off-by: Jeff Moyer <jmoyer@redhat.com>
* harness: Handle -ENOTSUP from io_submit() with RWF_NOWAITGuillem Jover2019-07-291-5/+7
| | | | | | | | | | On filesystems such as tmpfs the syscall might return -ENOTSUP instead of EINVAL when it does not support the RWF_NOWAIT flag.

* harness: Add fallback code for filesystems not supporting O_DIRECTGuillem Jover2019-07-294-5/+23
| | | | | | | | | | When running the harness on a filesystem such as a tmpfs, which do not support O_DIRECT, fallback to calls without the flag.

* harness: add support for skipping testsJeff Moyer2019-07-292-6/+28
| | | | | | | | Skipped tests will not cause the test harness to return failure. An exit status of "3" was chosen for skipped tests. This doesn't conflict with any of the current tests. Signed-off-by: Jeff Moyer <jmoyer@redhat.com>
* harness: Make the test exit with a code matching the pass/fail stateGuillem Jover2019-07-291-0/+2
| | | | | | | | This way we can use the exit code to check whether the tests passed or failed, and fail the package build. Signed-off-by: Guillem Jover <guillem@hadrons.org> Signed-off-by: Jeff Moyer <jmoyer@redhat.com>
* harness: Make RISC-V use SYS_eventfd2 instead of unavailable SYS_eventfdGuillem Jover2019-07-291-3/+3
| | | | | | | | This is a recent architecture and as such does not provide legacy support for SYS_eventfd. Declare that we need to use the new syscall. Signed-off-by: Guillem Jover <guillem@hadrons.org> Signed-off-by: Jeff Moyer <jmoyer@redhat.com>
* harness: Use run-time _SC_PAGE_SIZE instead of build-time PAGESIZEGuillem Jover2019-07-292-11/+25
| | | | | | | | | The getconf(1) command is inherently not cross-compilation friendly. In addition PAGESIZE depends on the specific system, even within a specific arch, so using a hard-coded value is never safe.

* harness: Use destination strncpy() expression for sizeof() argumentGuillem Jover2019-07-292-2/+2
| | | | | | | | | | | | | Even though this is the same size, as the sizeof() is derived from the source expression, recent gcc versions will emit a warning, which is turned into an error by -Werror: error: argument to ‘sizeof’ in ‘strncpy’ call is the same expression as the source; did you mean to use the size of the destination?

* Add support for preadv2/pwritev2Jeff Moyer2017-12-141-0/+176
| | | | | | | | | | | preadv2 and pwritev2 allow the caller to specify per-io flags. The main driver for this support in libaio is RWF_NOWAIT, which allows applications to specify that they don't want the submission thread to block waiting for things such as page cache invalidation, block instantiation, etc. This should help reduce unexpected latencies in the submission path.
