2016-03-03NVMe: Fix 0-length integrity payloadKeith Busch1-1/+1
A user could send a passthrough IO command with a metadata pointer to a namespace without metadata. With metadata length of 0, kmalloc returns ZERO_SIZE_PTR. Since that is not NULL, the driver would have set this as the bio's integrity payload, which causes an access fault on completion.

2016-03-03NVMe: Move error handling to failed reset handlerKeith Busch3-18/+50
This moves failed queue handling out of the namespace removal path and into the reset failure path, fixing a hanging condition if the controller fails or link down during del_gendisk. Previously the driver had to see the controller as degraded prior to calling del_gendisk to setup the queues to fail. But, if the controller happened to fail after this, there was no task to end outstanding requests. On failure, all namespace states are set to dead. This has capacity revalidate to 0, and ends all new requests with error status.

2016-03-03NVMe: Fix namespace removal deadlockKeith Busch3-7/+26
This patch makes nvme namespace removal lockless. It is up to the caller to ensure no active namespace scanning is occuring. To ensure no scan work occurs, the nvme pci driver adds a removing state to the controller device to avoid queueing scan work during removal. The work is flushed after setting the state, so no new scan work can be queued. The lockless removal allows the driver to cleanup a namespace request_queue if the controller fails during removal. Previously this could deadlock trying to acquire the namespace mutex in order to handle such events.

2016-03-03IB/{core, mlx5}: Fix input len in vendor part of create_qp/srqMajd Dibbiny2-11/+9
Currently, the inlen field of the vendor's part of the command doesn't match the command buffer. This happens because the inlen accommodates ib_uverbs_cmd_hdr which is deducted from the in buffer. This is problematic since the vendor function could be called either from the legacy verb (where the input length mismatches the actual length) or by the extended verb (where the length matches). The vendor has no idea which function calls it and therefore has no way to know how the length variable should be treated. Fixing this by aligning the inlen to the correct length. All vendor drivers either assumed that inlen >= sizeof(vendor_uhw_cmd) or just failed wrongly (mlx5) and fixed in this patch.

2016-03-02drm/amdgpu: return from atombios_dp_get_dpcd only when errorArindam Nath1-1/+1
In amdgpu_connector_hotplug(), we need to start DP link training only after we have received DPCD. The function amdgpu_atombios_dp_get_dpcd() returns non-zero value only when an error condition is met, otherwise returns zero. So in case the function encounters an error, we need to skip rest of the code and return from amdgpu_connector_hotplug() immediately. Only when we are successfull in reading DPCD pin, we should carry on with turning-on the monitor.

2016-03-02drm/radeon/pm: update current crtc info after setting the powerstateAlex Deucher1-4/+4
On CI, we need to see if the number of crtcs changes to determine whether or not we need to upload the mclk table again. In practice we don't currently upload the mclk table again after the initial load. The only reason you would would be to add new states, e.g., for arbitrary mclk setting which is not currently supported.
