2016-12-22qedr: ignore inline flag in read verbsAmrani, Ram1-1/+3
In the current implementation a read verb with IB_SEND_INLINE may be illegally configured. In this fix we ignore the inline bit in the case of a read verb.

2016-12-22qedr: modify QP state to error when destroying itAmrani, Ram1-2/+4
Current code didn't modify the QP state to error because it queried the QP state as a bitmap while it isn't. So the code never got executed. This patch fixes this and queries for each QP state respectively and not at once via a bitmask.

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 ...

2016-12-13IB/core: Let create_ah return extended response to userMoni Shoua2-2/+4
Add struct ib_udata to the signature of create_ah callback that is implemented by IB device drivers. This allows HW drivers to return extra data to the userspace library. This patch prepares the ground for mlx5 driver to resolve destination mac address for a given GID and return it to userspace.
