nvme-loop: Fix sqsize wrong assignment based on ctrl MQES capability

2017-04-09T19:58:07+00:00

both our sqsize and the controller MQES cap are a 0 based value, so making it 1 based is wrong. Reported-by: Trapp, Darren Reported-by: Daniel Verkamp Signed-off-by: Sagi Grimberg Reviewed-by: Christoph Hellwig Signed-off-by: Jens Axboe

nvmet: fix byte swap in nvmet_parse_io_cmd

2017-04-02T07:24:15+00:00

We need to do arithmetics after byte swapping, not before. Signed-off-by: Christoph Hellwig Signed-off-by: Sagi Grimberg

nvmet: fix byte swap in nvmet_execute_write_zeroes

2017-04-02T07:24:15+00:00

The length field in the Write Zeroes command is a 16-bit field. Signed-off-by: Christoph Hellwig Signed-off-by: Sagi Grimberg

nvmet: add missing byte swap in nvmet_get_smart_log

2017-04-02T07:24:15+00:00

In this case entirely harmless as it's all-ones, but still nice to shut up sparse. Signed-off-by: Christoph Hellwig Signed-off-by: Sagi Grimberg

nvme-loop: handle cpu unplug when re-establishing the controller

2017-03-21T16:38:46+00:00

If a cpu unplug event has occured, we need to take the minimum of the provided nr_io_queues and the number of online cpus, otherwise we won't be able to connect them as blk-mq mapping won't dispatch to those queues. Reviewed-by: Christoph Hellwig Signed-off-by: Sagi Grimberg

nvmet-rdma: Fix a possible uninitialized variable dereference

2017-03-16T16:41:24+00:00

When handling a new recv command, we grab a new rsp resource and check for the queue state being live. In case the queue is not in live state, we simply restore the rsp back to the free list. However in this flow we didn't set rsp->queue yet, so we cannot dereference it. Instead, make sure to initialize rsp->queue (and other rsp members) as soon as possible so we won't reference uninitialized variables.

nvmet: confirm sq percpu has scheduled and switched to atomic

2017-03-16T16:41:21+00:00

percpu_ref_kill is not enough to prevent subsequent percpu_ref_tryget_live from failing. Hence call perfcpu_ref_kill_confirm to make it safe. Reviewed-by: Christoph Hellwig Signed-off-by: Sagi Grimberg

nvme-loop: fix a possible use-after-free when destroying the admin queue

2017-03-16T16:41:17+00:00

we need to destroy the nvmet sq and let it finish gracefully before continue to cleanup the queue. Reviewed-by: Christoph Hellwig Signed-off-by: Sagi Grimberg

sched/headers: Prepare to use instead of in

2017-03-02T07:42:38+00:00

We don't actually need the full rculist.h header in sched.h anymore, we will be able to include the smaller rcupdate.h header instead. But first update code that relied on the implicit header inclusion.

According to the preceeding goto, it is likely that 'out_destroy_sq' was expected here. Signed-off-by: Christophe JAILLET Reviewed-by: Christoph Hellwig Signed-off-by: Sagi Grimberg Signed-off-by: Jens Axboe
