[src-openEuler/rdma-core] libhns: Bugfix for wrong timing of modifying ibv_qp state to err
by Chengchang Tang 01 Dec '23

01 Dec '23

From: Yangyang Li <liyangyang20(a)huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/rdma-core/issues/I8KG9M -------------------------------------------------------------------------- Currently the QPC state in HW is modified inside the critical section of spinlock but the ibv_qp state is modified outside. There will be a short period when QPC state has been modified to err with ibv_qp state still remaining RTS. WQEs during this period will still be post-send by RTS-state ibv_qp but then dropped by err-state HW with no flush CQEs generated. To fix this problem, the QPC state in HW and ibv_qp state should be both modified to err inside the critical section of spinlock.
