The final ACK that closes out an rxrpc call needs to be transmitted by the client unless we're going to follow up with a DATA packet for a new call on the same channel (which implicitly ACK's the previous call, thereby saving an ACK). Currently, we don't do that, so if no follow on call is immediately forthcoming, the server will resend the last DATA packet - at which point rxrpc_conn_retransmit_call() will be triggered and will (re)send the final ACK. But the server has to hold on to the last packet until the ACK is received, thereby holding up its resources. Fix the client side to propose a delayed final ACK, to be transmitted after a short delay, assuming the call isn't superseded by a new one. Signed-off-by: David Howells <dhowells@redhat.com> |
