Per NVMe-over-Fabrics 1.0 spec, sqsize is represented as a 0-based value. Also per spec, the RDMA binding values shall be set to sqsize, which makes hsqsize 0-based values. Thus, the sqsize during NVMf connect() is now: [root@fedora23-fabrics-host1 for-48]# dmesg [ 318.720645] nvme_fabrics: nvmf_connect_admin_queue(): sqsize for admin queue: 31 [ 318.720884] nvme nvme0: creating 16 I/O queues. [ 318.810114] nvme_fabrics: nvmf_connect_io_queue(): sqsize for i/o queue: 127 Finally, current interpretation implies hrqsize is 1's based so set it appropriately.

Upon admin queue connect(), the rdma qp was being set based on NVMF_AQ_DEPTH. However, the fabrics layer was using the sqsize field value set for I/O queues for the admin queue, which threw the nvme layer and rdma layer off-whack: root@fedora23-fabrics-host1 nvmf]# dmesg [ 3507.798642] nvme_fabrics: nvmf_connect_admin_queue():admin sqsize being sent is: 128 [ 3507.798858] nvme nvme0: creating 16 I/O queues. [ 3507.896407] nvme nvme0: new ctrl: NQN "nullside-nqn", addr 192.168.1.3:4420 Thus, to have a different admin queue value, we use NVMF_AQ_DEPTH for connect() and RDMA private data as the minimum depth specified in the NVMe-over-Fabrics 1.0 spec (and in that RDMA private data we treat hrqsize as 1's-based value, per current understanding of the fabrics spec).

Under extreme conditions this might cause data corruptions. By doing that we we repost the buffer and then post this buffer for the device to send. If we happen to use shared receive queues the device might write to the buffer before it sends it (there is no ordering between send and recv queues). Without SRQs we probably won't get that if the host doesn't mis-behave and send more than we allowed it, but relying on that is not really a good idea.

When configuring a device attached listener, we may see device removal events. In this case we return a non-zero return code from the cm event handler which implicitly destroys the cm_id. It is possible that in the future the user will remove this listener and by that trigger a second call to rdma_destroy_id on an already destroyed cm_id -> BUG. In addition, when a queue bound (active session) cm_id generates a DEVICE_REMOVAL event we must guarantee all resources are cleaned up by the time we return from the event handler. Introduce nvmet_rdma_device_removal which addresses (or at least attempts to) both scenarios. Signed-off-by: NSagi Grimberg <sagi@grimberg.me> Reviewed-by: NChristoph Hellwig <hch@lst.de>

If we wait until we free the controller (free_ctrl) we might lose our rdma device without any notification while we still have open resources (tags mrs and dma mappings). Instead, destroy the tags with their rdma resources once we delete the device and not when freeing it. Note that we don't do that in nvme_rdma_shutdown_ctrl because controller reset uses it as well and we want to give active I/O a chance to complete successfully.

Device removal sequence may have crashed because the controller (and admin queue space) was freed before we destroyed the admin queue resources. Thus we want to destroy the admin queue and only then queue controller deletion and wait for it to complete. More specifically we: 1. own the controller deletion (make sure we are not competing with another deletion). 2. get rid of inflight reconnects if exists (which also destroy and create queues). 3. destroy the queue. 4. safely queue controller deletion (and wait for it to complete).

On an ordered target shutdown, the target can send a AEN on a namespace removal, this will trigger the host to queue ns-list query. The shutdown will trigger error recovery which will attepmt periodic reconnect. We can hit a race where the ns rescanning fails (error recovery kicked in and we're not connected) causing removing all the namespaces and when we reconnect we won't see any namespaces for this controller. So, queue a namespace rescan after we successfully reconnected to the target. Signed-off-by: NSagi Grimberg <sagi@grimberg.me> Reviewed-by: NChristoph Hellwig <hch@lst.de>

On a system with sparse node ids, eg. a powerpc system with 4 nodes numbered like so: node 0: [mem 0x0000000000000000-0x00000007ffffffff] node 1: [mem 0x0000000800000000-0x0000000fffffffff] node 16: [mem 0x0000001000000000-0x00000017ffffffff] node 17: [mem 0x0000001800000000-0x0000001fffffffff] The code in rand_initialize() will allocate 4 pointers for the pool array, and initialise them correctly. However when go to use the pool, in eg. extract_crng(), we use the numa_node_id() to index into the array. For the higher numbered node ids this leads to random memory corruption, depending on what was kmalloc'ed adjacent to the pool array. Fix it by using nr_node_ids to size the pool array.

Pull NFS client updates from Trond Myklebust: "Highlights include: Stable bugfixes: - nfs: don't create zero-length requests - several LAYOUTGET bugfixes Features: - several performance related features - more aggressive caching when we can rely on close-to-open cache consistency - remove serialisation of O_DIRECT reads and writes - optimise several code paths to not flush to disk unnecessarily.
