A usual cycle for RDMA with a typical mix of driver and core subsystem updates. There was a lot of activity in the last week on fixing up some small patches that were merged during the rc8 period, so the top couple commits are new things that haven't been in linux-next, but they are all rc-ish unbreaking stuff. There is a compilation break after merging this, the signature of __sg_alloc_table_from_pages() was changed in this PR. The series that did this has been reviewed and been in linux-next for a while. You'll need to apply this fixup to the merge commit (it is in the tag for-linus-merged for reference): Thanks, Jason The following changes since commit 549738f15da0e5a00275977623be199fbbf7df50: Linux 5.9-rc8 (2020-10-04 16:04:34 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git tags/for-linus for you to fetch changes up to c7a198c700763ac89abbb166378f546aeb9afb33: RDMA/ucma: Fix use after free in destroy id flow (2020-10-16 14:07:08 -0300) ---------------------------------------------------------------- RDMA 5.10 pull request The typical set of driver updates across the subsystem: - Driver minor changes and bug fixes for mlx5, efa, rxe, vmw_pvrdma, hns, usnic, qib, qedr, cxgb4, hns, bnxt_re - Various rtrs fixes and updates - Bug fix for mlx4 CM emulation for virtualization scenarios where MRA wasn't working right - Use tracepoints instead of pr_debug in the CM code - Scrub the locking in ucma and cma to close more syzkaller bugs - Use tasklet_setup in the subsystem - Revert the idea that 'destroy' operations are not allowed to fail at the driver level. This proved unworkable from a HW perspective. - Revise how the umem API works so drivers make fewer mistakes using it - XRC support for qedr - Convert uverbs objects RWQ and MW to new the allocation scheme - Large queue entry sizes for hns - Use hmm_range_fault() for mlx5 On Demand Paging - uverbs APIs to inspect the GID table instead of sysfs - Move some of the RDMA code for building large page SGLs into lib/scatterlist ---------------------------------------------------------------- Aharon Landau (3): net/mlx5: Refactor query port speed functions RDMA/mlx5: Delete duplicated mlx5_ptys_width enum RDMA: Fix link active_speed size Alex Dewar (3): RDMA/qib: Remove superfluous fallthrough statements RDMA/qib: Tidy up process_cc() RDMA/ucma: Fix resource leak on error path Alex Vesker (3): RDMA/mlx5: Add sw_owner_v2 bit capability RDMA/mlx5: Allow DM allocation for sw_owner_v2 enabled devices RDMA/mlx5: Expose TIR and QP ICM address for sw_owner_v2 devices Allen Pais (5): RDMA/bnxt_re: Convert tasklets to use new tasklet_setup() API RDMA/hfi1: Convert tasklets to use new tasklet_setup() API RDMA/i40iw: Convert tasklets to use new tasklet_setup() API RDMA/qib: Convert tasklets to use new tasklet_setup() API RDMA/rxe: Convert tasklets to use new tasklet_setup() API Alok Prasad (1): RDMA/qedr: Endianness warnings cleanup Avihai Horon (4): RDMA/core: Change rdma_get_gid_attr returned error code RDMA/core: Modify enum ib_gid_type and enum rdma_network_type RDMA/core: Introduce new GID table query API RDMA/uverbs: Expose the new GID query API to user space Bob Pearson (8): RDMA/rxe: Fix style warnings RDMA/rxe: Add SPDX hdrs to rxe source files RDMA/rxe: Address an issue with hardened user copy RDMA/core: Added missing WR and WC opcodes RDMA/rxe: Remove duplicate entries in struct rxe_mr RDMA/rxe: Fix skb lifetime in rxe_rcv_mcast_pkt() RDMA/rxe: Fix bug rejecting all multicast packets RDMA/rxe: Handle skb_clone() failure in rxe_recv.c Chuck Lever (3): RDMA/core: Move the rdma_show_ib_cm_event() macro RDMA/cm: Replace pr_debug() call sites with tracepoints RDMA/cm: Add tracepoints to track MAD send operations Colin Ian King (2): RDMA/bnxt_re: Fix sizeof mismatch for allocation of pbl_tbl.
