xprtrdma: Remap Receive buffers after a reconnect

Browse source

[ Upstream commit 895cedc179 ]

On server-initiated disconnect, rpcrdma_xprt_disconnect() was DMA-
unmapping the Receive buffers, but rpcrdma_post_recvs() neglected
to remap them after a new connection had been established. The
result was immediate failure of the new connection with the Receives
flushing with LOCAL_PROT_ERR.
