The driver will clear all the interrupts in the same area when the driver handles the interrupt of type AEQ overflow. It should only set the interrupt status bit of type AEQ overflow.

The HNS NIC driver receives and handles the abnormal interrupt of the RAS type generated by ROCEE, and the HNS RDMA driver does not need to handle this type of interrupt. Therefore, delete unused codes in the HNS RDMA driver. Link: https://lore.kernel.org/r/20220714134353.16700-2-liangwenpeng@huawei.comSigned-off-by:

__qedr_alloc_mr() allocates a memory chunk for "mr->info.pbl_table" with init_mr_info(). When rdma_alloc_tid() and rdma_register_tid() fail, "mr" is released while "mr->info.pbl_table" is not released, which will lead to a memory leak. We should release the "mr->info.pbl_table" with qedr_free_pbl() when error occurs to fix the memory leak.

The mempool is for guaranteed memory allocation during extreme VM load (see the header of mempool.c of the kernel). But rtrs-srv allocates pages only when creating new session. There is no need to use the mempool. With the removal of mempool, rtrs-server no longer need to reserve huge mount of memory, this will avoid error like this: https://lore.kernel.org/lkml/20220620020727.GA3669@xsang-OptiPlex-9020/ Link: https://lore.kernel.org/r/20220712103113.617754-6-haris.iqbal@ionos.comReported-by:

When a local operation (invalidate mr, reg mr, bind mw) is finished there will be no ack packet coming from a responder to cause the wqe to be completed. This may happen anyway if a subsequent wqe performs IO. Currently if the wqe is signalled the completer tasklet is scheduled immediately but not otherwise. This leads to a deadlock if the next wqe has the fence bit set in send flags and the operation is not signalled. This patch removes the condition that the wqe must be signalled in order to schedule the completer tasklet which is the simplest fix for this deadlock and is fairly low cost. This is the analog for local operations of always setting the ackreq bit in all last or only request packets even if the operation is not signalled.

Currently the rdma_rxe driver has a security weakness due to giving objects which are partially initialized indices allowing external actors to gain access to them by sending packets which refer to their index (e.g. qpn, rkey, etc) causing unpredictable results. This patch adds a new API rxe_finalize(obj) which enables looking up pool objects from indices using rxe_pool_get_index() for AH, QP, MR, and MW. They are added in create verbs only after the objects are fully initialized. It also adds wait for completion to destroy/dealloc verbs to assure that all references have been dropped before returning to rdma_core by implementing a new rxe_pool API rxe_cleanup() which drops a reference to the object and then waits for all other references to be dropped. When the last reference is dropped the object is completed by kref. After that it cleans up the object and if locally allocated frees the memory. In the special case of address handle objects the delay is implemented separately if the destroy_ah call is not sleepable. Combined with deferring cleanup code to type specific cleanup routines this allows all pending activity referring to objects to complete before returning to rdma_core.
