2015-03-06Fix segfault with client/server and minimal outputJens Axboe
Fixes: bf2921f02651 Reported-by: Ben England <bengland@redhat.com> Signed-off-by: Jens Axboe <axboe@fb.com>
2015-03-06sha256: fix verify failureJens Axboe
After the checksumming update, it's required that we call the _final() to get consistent checksums between data generation and data verification. Seems to only affect sha256, but we should do it for sha1 and md5 too. Fixes: f99d67f932ab Signed-off-by: Jens Axboe <axboe@fb.com>

2015-03-06verify: always check completion list for low depth verifiesJens Axboe
If we have done less IO than the depth, we need to check the pending list. Signed-off-by: Jens Axboe <axboe@fb.com>

Signed-off-by: Jens Axboe <axboe@fb.com>
2015-03-06Improve precision of the io_limit settingJens Axboe
For async engines, we look only at completions. But we could have a bunch inflight with a high queue depth, making us go higher than we should. Signed-off-by: Jens Axboe <axboe@fb.com>
2015-03-06Improve rate limitingJens Axboe
If we have pending IO, we should commit it before going to sleep, not just wait for IO that has already been issued. Also improve the delay functions to return the time spent, so that users don't have to track tha separately if they care about the precision. Signed-off-by: Jens Axboe <axboe@fb.com>
2015-03-06rbd example: 'invalidate=false' no longer necessaryJens Axboe
As of commit 903b2812e9c7, rbd does support cache invalidation. Signed-off-by: Jens Axboe <axboe@fb.com>
2015-03-06client: take better care to return failure from fio_handle_clients()Jens Axboe
If any error has been noted in the ->error field, we need to pass back a non-zero return from fio_handle_clients(). Signed-off-by: Jens Axboe <axboe@fb.com>
2015-03-06smalloc: limit to 1 pool, and bump size to 16MBJens Axboe
We can easily add new pools, but if we do this after jobs have been forked off, then it wont really be shared storage as the new mmap mappings will only apply to the process that instantiated them. Since we moved the randommap mappings to private storage, we should not need a lot of room for shared allocations. Hence I hope the 16MB will suffice. Signed-off-by: Jens Axboe <axboe@fb.com>
2015-03-06axmap: random maps are private, don't get them from smallocJens Axboe
Signed-off-by: Jens Axboe <axboe@fb.com>
2015-03-06filelock: fix segfault on some use cases of log file lockingJens Axboe
If we end up diving into a new smalloc pool, we could add file lock references that meant nothing to other processes. Fixes: 243bfe190245 Signed-off-by: Jens Axboe <axboe@fb.com>

2015-03-06client: fix potential buffer overrun in server name copyJens Axboe
Not an issue right now since pdu.server is larger than the buffer, but that could change at some point. Better be safe. Signed-off-by: Jens Axboe <axboe@fb.com>

2015-03-06Get rid of lockfile callbackJens Axboe
We don't need it, since the option priorities take care of ordering. Signed-off-by: Jens Axboe <axboe@fb.com>
2015-03-06axmap: fix deadlockMing Lei
axmap_first_free() is always called with axmap->lock held, so needn't to acquire the lock inside the function. The deadlock is introduced in commit 12bde3697fc230d7a(axmap: ensure we lock down the maps for shared access). Given axmap_first_free() is only called inside lib/axmap.c, this patch declares the function as static. In the future, if external users need the function, axmap lock can be considered at that time.

2015-03-06gettime: add basic init cpuclock testJens Axboe
Some systems claim to have a synced and constant rate tsc, even if they don't. So add the basic cpuclock-test test as part of fio trusting the CPU clock, to avoid using the CPU clock on a system where the TSC truly isn't synced between CPUs. Signed-off-by: Jens Axboe <axboe@fb.com>

2015-03-06options: ensure that we check all candidates on is_set checkJens Axboe
We can have multiple options that touch the same variable. One example is cpus_allowed or cpumask, both will set the same backend variable. But if we set cpumask= and later check if cpus_allowed is set, then we want that to report true. This breaks certain options since b2a9e6496494.

2015-03-06Fix default scrambling of buffersJens Axboe
Commit 1bf2498d3111 inadvertently made us not scramble by default. The logic was a bit convoluted, so clear it up and scramble if: - Asked so by adding scramble_buffers=1 - Or, if not asked to explicitly, but zero_buffers not set to 1.

2015-03-06options: turn missing options into debug parse messagesJens Axboe
It's not an error, we expect it to happen if we try and check for set options that aren't available (due to being platform specific, libraries missing, etc). This fixes cases where fio would spew: fio: no option found at offset 1240 and other offsets. Signed-off-by: Jens Axboe <axboe@fb.com>

We have to remember to free the condvar, so add a __fio_mutex_remove() for cases that init a mutex inside an smalloc'ed region with __fio_mutex_init(). Signed-off-by: Jens Axboe <axboe@fb.com>
