RDMA/iwcm: Reject connect requests if cmid is not in LISTEN state
When destroying a listening cmid, the iwcm first marks the state of the cmid as DESTROYING, then releases the lock and calls into the iWARP provider to destroy the endpoint. Since the cmid is not locked, its possible for the iWARP provider to pass a connection request event to the iwcm, which will be silently dropped by the iwcm. This causes the iWARP provider to never free up the resources from this connection because the assumption is the iwcm will accept or reject this connection. The solution is to reject these connection requests. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
