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 ...

Pull verbs counters series from Leon Romanovsky: ==================== Verbs flow counters support This series comes to allow user space applications to monitor real time traffic activity and events of the verbs objects it manages, e.g.: ibv_qp, ibv_wq, ibv_flow. The API enables generic counters creation and define mapping to association with a verbs object, the current mlx5 driver is using this API for flow counters. With this API, an application can monitor the entire life cycle of object activity, defined here as a static counters attachment. This API also allows dynamic counters monitoring of measurement points for a partial period in the verbs object life cycle. In addition it presents the implementation of the generic counters interface. This will be achieved by extending flow creation by adding a new flow count specification type which allows the user to associate a previously created flow counters using the generic verbs counters interface to the created flow, once associated the user could read statistics by using the read function of the generic counters interface. The API includes: 1. create and destroyed API of a new counters objects 2. read the counters values from HW Note: Attaching API to allow application to define the measurement points per objects is a user space only API and this data is passed to kernel when the counted object (e.g. flow) is created with the counters object. =================== * tag 'verbs_flow_counters': 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 IB/core: Add support for flow counters IB/core: Support passing uhw for create_flow IB/uverbs: Add read counters support IB/core: Introduce counters read verb IB/uverbs: Add create/destroy counters support IB/core: Introduce counters object and its create/destroy IB/uverbs: Add an ib_uobject getter to ioctl() infrastructure net/mlx5: Export flow counter related API net/mlx5: Use flow counter pointer as input to the query function

IB/mlx5: Add flow counters binding support

2018-06-02T04:35:32Z

Associates a counters with a flow when IB_FLOW_SPEC_ACTION_COUNT is part of the flow specifications. The counters user space placements of location and description (index, description) pairs are passed as private data of the counters flow specification.

net/mlx5: Add FPGA QP error event

The FPGA queue pair (QP) event fires whenever a QP on the FPGA transitions to the error state. At this stage, this event is unrecoverable, it may become recoverable in the future. Signed-off-by: Ilan Tayari Signed-off-by: Adi Nissim Signed-off-by: Saeed Mahameed Signed-off-by: David S. Miller

net/mlx5: Use order-0 allocations for all WQ types

2018-05-25T21:11:00Z

Complete the transition of all WQ types to use fragmented order-0 coherent memory instead of high-order allocations. CQ-WQ already uses order-0. Here we do the same for cyclic and linked-list WQs. This allows the driver to load cleanly on systems with a highly fragmented coherent memory.
