Re: [Linux-stable-mirror] [PATCH] RDMA/rxe: Fix a race condition related to the QP error state

Maybe I am missing something but I think that the race is when qp is in ERROR state and the following functions run in parallel

• rxe_drain_req_pkts (called from rxe_requester after post_send)
• rxe_drain_resp_pkts (called from rxe_completer after modify to ERROR)

Am I right?

Hello Moni,

I think that's a real race and a race that has to be fixed but not the race that caused the missing completions in the tests I ran myself.

Best regards,

Bart.
