  - RDMA/irdma修复 CQP 完成统计数据上的争用 CQP 完成统计数据可在 irdma_wait_event 和 irdma_check_cqp_progress 中被锁定读取而据 KCSAN 报告可在另一个 CPU 上的完成线程 irdma_sc_ccq_get_cqe_info 中更新。使完成统计数据成为一个原子变量以反映对其进行的一致更新。这也将避免编译器优化可能导致的加载/存储拆分逻辑缺陷。 [77346.170861] BUGKCSAN在 irdma_handle_cqp_op 中发生数据争用 [irdma] / irdma_sc_ccq_get_cqe_info [irdma] [77346.171383] 在 cpu 4 上通过任务 9544 写入 8 字节的 0xffff8a3250b108e0 [77346.171483] irdma_sc_ccq_get_cqe_info+0x327a/] [77346.171658] irdma_cqp_ce_handler+0x164/0x270 [irdma] [77346.171835] cqp_compl_worker+0x1b/0x20 [irdma] [77346.172009] process_one_work+0x4d1/0xa40 [77346.172024] worker_thread+0x319/0x700 [77346.172037] kthread+0x180/ 0x1b0 [77346.172054] ret_from_fork+0x22/0x30 [77346.172136] 任务 9838 在 cpu 2 上读取 8 个字节的 0xffff8a3250b108e0 [77346.172234] irdma_handle_cqp_op+0xf4/0x4b0 [irdma] [77346.172413] irdma_cqp_aeq_cmd+0x0x75/irdma_cqp_aeq_cmd+0x75/ ] [77346.172592] irdma_create_aeq+0x390/0x45a [irdma] [77346.172769] irdma_rt_init_hw.cold+0x212/0x85d [irdma] [77346.172944] irdma_probe+0x54f/0x620 [irdma] [77346.173122] auxiliary_bus_probe+0x66/0xa0 [77346.173137] real_probe+0x140/0x540 [77346.173154]
