From ddc7834af8d56c2c0e805f05493ba4a650c0344f Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 30 Sep 2020 23:54:44 +0100 Subject: rxrpc: Fix loss of final ack on shutdown Fix the loss of transmission of a call's final ack when a socket gets shut down. This means that the server will retransmit the last data packet or send a ping ack and then get an ICMP indicating the port got closed. The server will then view this as a failure.
