2021-08-30Merge branch 'sg_nents' into rdma.git for-nextJason Gunthorpe1417-11263/+18008
From Maor Gottlieb ==================== Fix the use of nents and orig_nents in the sg table append helpers. The nents should be used by the DMA layer to store the number of DMA mapped sges, the orig_nents is the number of CPU sges. Since the sg append logic doesn't always create a SGL with exactly orig_nents entries store a total_nents as well to allow the table to be properly free'd and reorganize the freeing logic to share across all the use cases. ==================== Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> * 'sg_nents': RDMA: Use the sg_table directly and remove the opencoded version from umem lib/scatterlist: Fix wrong update of orig_nents lib/scatterlist: Provide a dedicated function to support table append

2021-08-25RDMA/hns: Bugfix for incorrect association between dip_idx and dgidJunxian Huang4-5/+31
dip_idx and dgid should be a one-to-one mapping relationship, but when qp_num loops back to the start number, it may happen that two different dgid are assiociated to the same dip_idx incorrectly. One solution is to store the qp_num that is not assigned to dip_idx in an array. When a dip_idx needs to be allocated to a new dgid, an spare qp_num is extracted and assigned to dip_idx.

2021-08-25RDMA/core/sa_query: Retry SA queriesHåkon Bugge2-1/+11
A MAD packet is sent as an unreliable datagram (UD). SA requests are sent as MAD packets. As such, SA requests or responses may be silently dropped. IB Core's MAD layer has a timeout and retry mechanism, which amongst other, is used by RDMA CM. But it is not used by SA queries. The lack of retries of SA queries leads to long specified timeout, and error being returned in case of packet loss. The ULP or user-land process has to perform the retry. Fix this by taking advantage of the MAD layer's retry mechanism. First, a check against a zero timeout is added in rdma_resolve_route(). In send_mad(), we set the MAD layer timeout to one tenth of the specified timeout and the number of retries to 10. The special case when timeout is less than 10 is handled. With this fix: # ucmatose -c 1000 -S 1024 -C 1 runs stable on an Infiniband fabric. Without this fix, we see an intermittent behavior and it errors out with: cmatose: event: RDMA_CM_EVENT_ROUTE_ERROR, error: -110 (110 is ETIMEDOUT) Link: https://lore.kernel.org/r/1628784755-28316-1-git-send-email-haakon.bugge@oracle.com Signed-off-by: Håkon Bugge <haakon.bugge@oracle.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

2021-08-25lib/scatterlist: Fix wrong update of orig_nentsMaor Gottlieb6-93/+136
orig_nents should represent the number of entries with pages, but __sg_alloc_table_from_pages sets orig_nents as the number of total entries in the table. This is wrong when the API is used for dynamic allocation where not all the table entries are mapped with pages. It wasn't observed until now, since RDMA umem who uses this API in the dynamic form doesn't use orig_nents implicit or explicit by the scatterlist APIs. Fix it by changing the append API to track the SG append table state and have an API to free the append table according to the total number of entries in the table. Now all APIs set orig_nents as number of enries with pages.

2021-08-23RDMA/rtrs-clt: Fix counting inflight IOGioh Kim3-4/+6
There are mis-match at counting inflight IO after changing the multipath policy. For example, we started fio test with round-robin policy and then we changed the policy to min-inflight. IOs created under the RR policy is finished under the min-inflight policy and inflight counter only decreased. So the counter would be negative value. And also we started fio test with min-inflight policy and changed the policy to the round-robin. IOs created under the min-inflight policy increased the inflight IO counter but the inflight IO counter was not decreased because the policy was the round-robin when IO was finished. So it should count IOs only if the IO is created under the min-inflight policy. It should not care the policy when the IO is finished. This patch adds a field mp_policy in struct rtrs_clt_io_req and stores the multipath policy when an object of rtrs_clt_io_req is created. Then rtrs-clt checks the mp_policy of only struct rtrs_clt_io_req instead of the struct rtrs_clt.

ib_sa_service_rec_query() was introduced in kernel v2.6.13 by commit cbae32c56314 ("[PATCH] IB: Add Service Record support to SA client") in 2005. It was not used then and have never been used since.

2021-08-19RDMA/qedr: Move variables reset to qedr_set_common_qp_params()Prabhakar Kushwaha1-18/+14
Qedr code is tightly coupled with existing both INIT transitions. Here, during first INIT transition all variables are reset and the RESET state is checked in post_recv() before any posting. Commit dc70f7c3ed34 ("RDMA/cma: Remove unnecessary INIT->INIT transition") exposed this bug. So moving variables reset to qedr_set_common_qp_params() and also avoid RESET state check for post_recv().
