RDMA/vmw_pvrdma: Fix network_hdr_type reported in WC

2021-01-20T00:17:27Z

The PVRDMA device HW interface defines network_hdr_type according to an old definition of the internal kernel rdma_network_type enum that has since changed, resulting in the wrong rdma_network_type being reported. Fix this by explicitly defining the enum used by the PVRDMA device and adding a function to convert the pvrdma_network_type to rdma_network_type enum.

RDMA/rxe: Use acquire/release for memory ordering

2020-12-11T23:57:48Z

Change work and completion queues to use smp_load_acquire() and smp_store_release() to synchronize between driver and users. This commit goes with a matching series of commits in the rxe user space provider.

RDMA/hns: Move capability flags of QP and CQ to hns-abi.h

2020-12-07T19:48:51Z

These flags will be returned to the userspace through ABI, so they should be defined in hns-abi.h. Furthermore, there is no need to include hns-abi.h in every source files, it just needs to be included in the common header file.

RDMA: Check attr_mask during modify_qp

2020-10-26T22:27:58Z

Each driver should check that it can support the provided attr_mask during modify_qp. IB_USER_VERBS_EX_CMD_MODIFY_QP was being used to block modify_qp_ex because the driver didn't check RATE_LIMIT.

RDMA/rxe: Move the definitions for rxe_av.network_type to uAPI

2020-10-16T16:54:10Z

RXE was wrongly using an internal kernel enum as part of its uAPI, split this out into a dedicated uAPI enum just for RXE. It only uses the IPv4 and IPv6 values. This was exposed by changing the internal kernel enum definition which broke RXE. Fixes: 1c15b4f2a42f ("RDMA/core: Modify enum ib_gid_type and enum rdma_network_type") Signed-off-by: Jason Gunthorpe

RDMA/uverbs: Expose the new GID query API to user space

2020-10-02T00:20:11Z

Expose the query GID table and entry API to user space by adding two new methods and method handlers to the device object. This API provides a faster way to query a GID table using single call and will be used in libibverbs to improve current approach that requires multiple calls to open, close and read multiple sysfs files for a single GID table entry.
