Description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/irdma: Fix data race on CQP request done

KCSAN detects a data race on cqp_request->request_done memory location which is accessed locklessly in irdma_handle_cqp_op while being updated in irdma_cqp_ce_handler.

Annotate lockless intent with READ_ONCE/WRITE_ONCE to avoid any compiler optimizations like load fusing and/or KCSAN warning.
