nvmet-rdma: Fix missing dma sync to nvme data structures

2017-01-26T15:45:03+00:00

This patch performs dma sync operations on nvme_command and nvme_completion. nvme_command is synced (a) on receiving of the recv queue completion for cpu access. (b) before posting recv wqe back to rdma adapter for device access. nvme_completion is synced (a) on receiving of the recv queue completion of associated nvme_command for cpu access. (b) before posting send wqe to rdma adapter for device access.

nvmet: Call fatal_error from keep-alive timout expiration

2017-01-26T15:45:03+00:00

We only need to call delete_ctrl once, so given that both keep-alive timeout and any other fatal error can trigger it, just make sure we only call delete_ctrl once. Signed-off-by: Sagi Grimberg Reviewed-by: Christoph Hellwig

nvmet: cancel fatal error and flush async work before free controller

Make sure they are not running and we can free the controller safely. Signed-off-by: Roy Shterman Signed-off-by: Sagi Grimberg Reviewed-by: Christoph Hellwig

nvmet: delete controllers deletion upon subsystem release

2017-01-26T15:44:22+00:00

No reason for them to be kept around if we are deleting the subsystem, so instead of passively wait for the host to disconnect, actively delete the controllers. Signed-off-by: Sagi Grimberg Reviewed-by: Johannes Thumshirn Reviewed-by: Max Gurtovoy Reviewed-by: Christoph Hellwig

nvmet/fcloop: remove some logically dead code performing redundant ret checks

2016-12-21T10:34:28+00:00

The check to see if ret is non-zero and return this rather than count is redundant in two occassions. It is redundant because prior to this check, the return code ret is already checked for a non-zero error return value and we return from the function at that point.

nvmet: fix KATO offset in Set Features

2016-12-21T10:34:27+00:00

The Set Features implementation for Keep Alive Timer was using the wrong structure when retrieving the KATO value; it was treating the Set Features command as a Property Set command. The NVMe spec defines the Keep Alive Timer feature as having one input in CDW11 (4 bytes at offset 44 in the command) whereas the code was reading 8 bytes at offset 48. Since the Linux NVMe over Fabrics host never sets this feature, this code has presumably never been tested. Signed-off-by: Daniel Verkamp Signed-off-by: Christoph Hellwig

Pull rdma updates from Doug Ledford: "This is the complete update for the rdma stack for this release cycle. Most of it is typical driver and core updates, but there is the entirely new VMWare pvrdma driver. You may have noticed that there were changes in DaveM's pull request to the bnxt Ethernet driver to support a RoCE RDMA driver. The bnxt_re driver was tentatively set to be pulled in this release cycle, but it simply wasn't ready in time and was dropped (a few review comments still to address, and some multi-arch build issues like prefetch() not working across all arches). Summary: - shared mlx5 updates with net stack (will drop out on merge if Dave's tree has already been merged) - driver updates: cxgb4, hfi1, hns-roce, i40iw, mlx4, mlx5, qedr, rxe - debug cleanups - new connection rejection helpers - SRP updates - various misc fixes - new paravirt driver from vmware" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (210 commits) IB: Add vmw_pvrdma driver IB/mlx4: fix improper return value IB/ocrdma: fix bad initialization infiniband: nes: return value of skb_linearize should be handled MAINTAINERS: Update Intel RDMA RNIC driver maintainers MAINTAINERS: Remove Mitesh Ahuja from emulex maintainers IB/core: fix unmap_sg argument qede: fix general protection fault may occur on probe IB/mthca: Replace pci_pool_alloc by pci_pool_zalloc mlx5, calc_sq_size(): Make a debug message more informative mlx5: Remove a set-but-not-used variable mlx5: Use { } instead of { 0 } to init struct IB/srp: Make writing the add_target sysfs attr interruptible IB/srp: Make mapping failures easier to debug IB/srp: Make login failures easier to debug IB/srp: Introduce a local variable in srp_add_one() IB/srp: Fix CONFIG_DYNAMIC_DEBUG=n build IB/multicast: Check ib_find_pkey() return value IPoIB: Avoid reading an uninitialized member variable IB/mad: Fix an array index check ...
