Pull rdma fixes from Doug Ledford: "Final set of -rc fixes for 4.6. I've collected up a number of patches that are all pretty small with the exception of only a couple. The hfi1 driver has a number of important patches, and it is what really drives the line count of this pull request up. These are all small and I've got this kernel built and running in the test lab (I have most of the hardware, I think nes is the only thing in this patch set that I can't say I've personally tested and have up and running). Summary: - A number of collected fixes for oopses, memory corruptions, deadlocks, etc. All of these fixes are small (many only 5-10 lines), obvious, and tested. - Fix for the security issue related to the use of write for bi-directional communications" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: RDMA/nes: don't leak skb if carrier down IB/security: Restrict use of the write() interface IB/hfi1: Use kernel default llseek for ui device IB/hfi1: Don't attempt to free resources if initialization failed IB/hfi1: Fix missing lock/unlock in verbs drain callback IB/rdmavt: Fix send scheduling IB/hfi1: Prevent unpinning of wrong pages IB/hfi1: Fix deadlock caused by locking with wrong scope IB/hfi1: Prevent NULL pointer deferences in caching code MAINTAINERS: Update iser/isert maintainer contact info IB/mlx5: Expose correct max_sge_rd limit RDMA/iw_cxgb4: Fix bar2 virt addr calculation for T4 chips iw_cxgb4: handle draining an idle qp iw_cxgb3: initialize ibdev.iwcm->ifname for port mapping iw_cxgb4: initialize ibdev.iwcm->ifname for port mapping IB/core: Don't drain non-existent rq queue-pair IB/core: Fix oops in ib_cache_gid_set_default_gid

IB/mlx5: Expose correct max_sge_rd limit

2016-04-28T14:49:17Z

mlx5 devices (Connect-IB, ConnectX-4, ConnectX-4-LX) has a limitation where rdma read work queue entries cannot exceed 512 bytes. A rdma_read wqe needs to fit in 512 bytes: - wqe control segment (16 bytes) - rdma segment (16 bytes) - scatter elements (16 bytes each) So max_sge_rd should be: (512 - 16 - 16) / 16 = 30.

net/mlx5: Add pci shutdown callback

2016-04-24T18:51:39Z

This patch introduces kexec support for mlx5. When switching kernels, kexec() calls shutdown, which unloads the driver and cleans its resources. In addition, remove unregister netdev from shutdown flow. This will allow a clean shutdown, even if some netdev clients did not release their reference from this netdev. Releasing The HW resources only is enough as the kernel is shutting down Signed-off-by: Majd Dibbiny Signed-off-by: Tariq Toukan Signed-off-by: Haggai Abramovsky Signed-off-by: Saeed Mahameed Signed-off-by: David S.

net/mlx5e: Use vport MTU rather than physical port MTU

2016-04-24T18:51:39Z

Set and report vport MTU rather than physical MTU, Driver will set both vport and physical port mtu and will rely on the query of vport mtu. SRIOV VFs have to report their MTU to their vport manager (PF), and this will allow them to work with any MTU they need without failing the request. Also for some cases where the PF is not a port owner, PF can work with MTU less than the physical port mtu if set physical port mtu didn't take effect.

net/mlx5e: Device's mtu field is u16 and not int

2016-04-24T18:51:38Z

For set/query MTU port firmware commands the MTU field is 16 bits, here I changed all the "int mtu" parameters of the functions wrapping those firmware commands to be u16. Signed-off-by: Saeed Mahameed Signed-off-by: David S. Miller

Pull more rdma updates from Doug Ledford: "Round two of 4.6 merge window patches. This is a monster pull request. I held off on the hfi1 driver updates (the hfi1 driver is intimately tied to the qib driver and the new rdmavt software library that was created to help both of them) in my first pull request. The hfi1/qib/rdmavt update is probably 90% of this pull request. The hfi1 driver is being left in staging so that it can be fixed up in regards to the API that Al and yourself didn't like. Intel has agreed to do the work, but in the meantime, this clears out 300+ patches in the backlog queue and brings my tree and their tree closer to sync. This also includes about 10 patches to the core and a few to mlx5 to create an infrastructure for configuring SRIOV ports on IB devices. That series includes one patch to the net core that we sent to netdev@ and Dave Miller with each of the three revisions to the series. We didn't get any response to the patch, so we took that as implicit approval. Finally, this series includes Intel's new iWARP driver for their x722 cards. It's not nearly the beast as the hfi1 driver. It also has a linux-next merge issue, but that has been resolved and it now passes just fine. Summary: - A few minor core fixups needed for the next patch series - The IB SRIOV series. This has bounced around for several versions. Of note is the fact that the first patch in this series effects the net core. It was directed to netdev and DaveM for each iteration of the series (three versions total). Dave did not object, but did not respond either. I've taken this as permission to move forward with the series. - The new Intel X722 iWARP driver - A huge set of updates to the Intel hfi1 driver. Of particular interest here is that we have left the driver in staging since it still has an API that people object to. Intel is working on a fix, but getting these patches in now helps keep me sane as the upstream and Intel's trees were over 300 patches apart" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (362 commits) IB/ipoib: Allow mcast packets from other VFs IB/mlx5: Implement callbacks for manipulating VFs net/mlx5_core: Implement modify HCA vport command net/mlx5_core: Add VF param when querying vport counter IB/ipoib: Add ndo operations for configuring VFs IB/core: Add interfaces to control VF attributes IB/core: Support accessing SA in virtualized environment IB/core: Add subnet prefix to port info IB/mlx5: Fix decision on using MAD_IFC net/core: Add support for configuring VF GUIDs IB/{core, ulp} Support above 32 possible device capability flags IB/core: Replace setting the zero values in ib_uverbs_ex_query_device net/mlx5_core: Introduce offload arithmetic hardware capabilities net/mlx5_core: Refactor device capability function net/mlx5_core: Fix caching ATOMIC endian mode capability ib_srpt: fix a WARN_ON() message i40iw: Replace the obsolete crypto hash interface with shash IB/hfi1: Add SDMA cache eviction algorithm IB/hfi1: Switch to using the pin query function IB/hfi1: Specify mm when releasing pages ...

IB/mlx5: Implement callbacks for manipulating VFs

2016-03-21T21:13:14Z

Implement the IB defined callbacks used to manipulate the policy for the link state, set GUIDs or get statistics information. This functionality is added into a new file that will be used to add any SRIOV related functionality to the mlx5 IB layer. The following callbacks have been added: mlx5_ib_get_vf_config mlx5_ib_set_vf_link_state mlx5_ib_get_vf_stats mlx5_ib_set_vf_guid In addition, publish whether this device is based on a virtual function. In mlx5 supported devices, virtual functions are implemented as vHCAs. vHCAs have their own QP number space so it is possible that two vHCAs will use a QP with the same number at the same time.

net/mlx5_core: Add VF param when querying vport counter

2016-03-21T21:13:14Z

Add a vf parameter to mlx5_core_query_vport_counter so we can call it to query counters of virtual functions. Also update current users of the API. PFs may call mlx5_core_query_vport_counter with other_vport set to indicate that they are querying a virtual function. The virtual function to be queried is given by the vf parameter. Virtual function numbering is zero based so the first VF is 0 and so on. When a PF queries its own function, the other_vport parameter is cleared.
