Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe: "This has been a quiet cycle for RDMA, the big bulk is the usual smallish driver updates and bug fixes. About four new uAPI related things. Not as much Szykaller patches this time, the bugs it finds are getting harder to fix. Summary: - More work cleaning up the RDMA CM code - Usual driver bug fixes and cleanups for qedr, qib, hfi1, hns, i40iw, iw_cxgb4, mlx5, rxe - Driver specific resource tracking and reporting via netlink - Continued work for name space support from Parav - MPLS support for the verbs flow steering uAPI - A few tricky IPoIB fixes improving robustness - HFI1 driver support for the '16B' management packet format - Some auditing to not print kernel pointers via %llx or similar - Mark the entire 'UCM' user-space interface as BROKEN with the intent to remove it entirely. The user space side of this was long ago replaced with RDMA-CM and syzkaller is finding bugs in the residual UCM interface nobody wishes to fix because nobody uses it. - Purge more bogus BUG_ON's from Leon - 'flow counters' verbs uAPI - T10 fixups for iser/isert, these are Acked by Martin but going through the RDMA tree due to dependencies" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (138 commits) RDMA/mlx5: Update SPDX tags to show proper license RDMA/restrack: Change SPDX tag to properly reflect license IB/hfi1: Fix comment on default hdr entry size IB/hfi1: Rename exp_lock to exp_mutex IB/hfi1: Add bypass register defines and replace blind constants IB/hfi1: Remove unused variable IB/hfi1: Ensure VL index is within bounds IB/hfi1: Fix user context tail allocation for DMA_RTAIL IB/hns: Use zeroing memory allocator instead of allocator/memset infiniband: fix a possible use-after-free bug iw_cxgb4: add INFINIBAND_ADDR_TRANS dependency IB/isert: use T10-PI check mask definitions from core layer IB/iser: use T10-PI check mask definitions from core layer RDMA/core: introduce check masks for T10-PI offload IB/isert: fix T10-pi check mask setting IB/mlx5: Add counters read support IB/mlx5: Add flow counters read support IB/mlx5: Add flow counters binding support IB/mlx5: Add counters create and destroy support IB/uverbs: Add support for flow counters ...
