Mostly the usual list of one or two patches to drivers changing something that isn't quite rc worthy. The subsystem seems to be seeing a larger number of rework and cleanup style patches right now, I feel that several vendors are prepping their drivers for new silicon. Summary: - Driver updates and cleanup for qedr, bnxt_re, hns, siw, mlx5, mlx4, rxe, i40iw - Larger series doing cleanup and rework for hns and hfi1. - Some general reworking of the CM code to make it a little more understandable - Unify the different code paths connected to the uverbs FD scheme - New UAPI ioctls conversions for get context and get async fd - Trace points for CQ and CM portions of the RDMA stack - mlx5 driver support for virtio-net formatted rings as RDMA raw ethernet QPs - verbs support for setting the PCI-E relaxed ordering bit on DMA traffic connected to a MR - A couple of bug fixes that came too late to make rc7" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (108 commits) RDMA/core: Make the entire API tree static RDMA/efa: Mask access flags with the correct optional range RDMA/cma: Fix unbalanced cm_id reference count during address resolve RDMA/umem: Fix ib_umem_find_best_pgsz() IB/mlx4: Fix leak in id_map_find_del IB/opa_vnic: Spelling correction of 'erorr' to 'error' IB/hfi1: Fix logical condition in msix_request_irq RDMA/cm: Remove CM message structs RDMA/cm: Use IBA functions for complex structure members RDMA/cm: Use IBA functions for simple structure members RDMA/cm: Use IBA functions for swapping get/set acessors RDMA/cm: Use IBA functions for simple get/set acessors RDMA/cm: Add SET/GET implementations to hide IBA wire format RDMA/cm: Add accessors for CM_REQ transport_type IB/mlx5: Return the administrative GUID if exists RDMA/core: Ensure that rdma_user_mmap_entry_remove() is a fence IB/mlx4: Fix memory leak in add_gid error flow IB/mlx5: Expose RoCE accelerator counters RDMA/mlx5: Set relaxed ordering when requested RDMA/core: Add the core support field to METHOD_GET_CONTEXT ... 2020-01-25T18:54:39+00:00 Danit Goldberg danitg@mellanox.com 2020-01-16T12:00:48+00:00 urn:sha1:4bbd4923d1f5627b0c47a9d7dfb5cc91224cfe0c A user can change the operational GUID (a.k.a affective GUID) through link/infiniband. Therefore it is preferred to return the currently set GUID if it exists instead of the operational. This way the PF can query which VF GUID will be set in the next bind. In order to align with MAC address, zero is returned if administrative GUID is not set. For example, before setting administrative GUID: $ ip link show ib0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 00:00:00:00:00:00:00:00, PORT_GUID 00:00:00:00:00:00:00:00, link-state auto, trust off, query_rss off Then: $ ip link set ib0 vf 0 node_guid 11:00:af:21:cb:05:11:00 $ ip link set ib0 vf 0 port_guid 22:11:af:21:cb:05:11:00 After setting administrative GUID: $ ip link show ib0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 11:00:af:21:cb:05:11:00, PORT_GUID 22:11:af:21:cb:05:11:00, link-state auto, trust off, query_rss off Fixes: 9c0015ef0928 ("IB/mlx5: Implement callbacks for getting VFs GUID attributes") Link: https://lore.kernel.org/r/20200116120048.12744-1-leon@kernel.org Signed-off-by: Danit Goldberg <danitg@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> 2020-01-16T23:48:24+00:00 Saeed Mahameed saeedm@mellanox.com 2020-01-16T23:46:42+00:00 urn:sha1:12e9e0d0d97cc4f2aa9a858ac8a5741f321b5287 This merge syncs with mlx5-next latest HW bits and layout updates for next features, in addition one patch that improves mlx5_create_auto_grouped_flow_table() API across all mlx5 users. * 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Refactor mlx5_create_auto_grouped_flow_table net/mlx5e: Add discard counters per priority net/mlx5e: Expose FEC feilds and related capability bit net/mlx5: Add mlx5_ifc definitions for connection tracking support net/mlx5: Add copy header action struct layout net/mlx5: Expose resource dump register mapping net/mlx5: Add structures and defines for MIRC register net/mlx5: Read MCAM register groups 1 and 2 net/mlx5: Add structures layout for new MCAM access reg groups net/mlx5: Expose vDPA emulation device capabilities net/mlx5: Add Virtio Emulation related device capabilities Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> 2020-01-16T22:11:23+00:00 Aya Levin ayal@mellanox.com 2019-11-04T12:51:55+00:00 urn:sha1:609b82727f719b41b50440c4028d48d0b2e04913 Add new register enumeration for resource dump.

The functionality to set VF GUIDs already existed for a long time, and here we are adding the missing "get" so that netlink will be symmetric and various cloud orchestration tools will be able to manage such VFs more naturally.
