[PATCH 01/20] nvme-rdma: remove redundant reference between ib_device and tagset
by Yang Yingliang 22 Oct '20

22 Oct '20

From: Max Gurtovoy <maxg(a)mellanox.com> mainline inclusion from mainline-v5.2-rc1 commit 87fd125344d68adf7699ec7396aa9f905ce79a80 category: bugfix bugzilla: NA CVE: NA Link: https://gitee.com/openeuler/kernel/issues/I1WGZE ------------------------------------------------- In the past, before adding f41725bb ("nvme-rdma: Use mr pool") commit, we needed a reference on the ib_device as long as the tagset was alive, as the MRs in the request structures needed a valid ib_device. Now, we allocate/deallocate MR pool per QP and consume on demand. Also remove nvme_rdma_free_tagset function and use blk_mq_free_tag_set instead, as it unneeded anymore. This commit also fixes a memory leakage and possible segmentation fault. When configuring the system with NIC teaming (aka bonding), we use 1 network interface to create an HA connection to the target side. In case one connection breaks down, nvme-rdma driver will get notification from rdma-cm layer that underlying address was change and will start error recovery process. During this process, we'll reconnect to the target via the second interface in the bond without destroying the tagset. This will cause a leakage of the initial rdma device (ndev) and miscount in the reference count of the new created rdma device (new ndev). In the final destruction (or in another error flow), we'll get a warning dump from the ib_dealloc_pd that we still have inflight MR's related to that pd. This happens becasue of the miscount of the reference tag of the rdma device and causing access violation to it's elements (some queues are not destroyed yet).
