From fb1967a69f756073362b8f19347f863f227320ad Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 6 Jun 2018 14:59:14 +0100 Subject: [PATCH] rxrpc: Fix terminal retransmission connection ID to include the channel When retransmitting the final ACK or ABORT packet for a call, the cid field in the packet header is set to the connection's cid, but this is incorrect as it also needs to include the channel number on that connection that the call was made on. Fix this by OR'ing in the channel number. Note that this fixes the bug that: commit 1a025028d400b23477341aa7ec2ce55f8b39b554 rxrpc: Fix handling of call quietly cancelled out on server works around. I'm not intending to revert that as it will help protect against problems that might occur on the server.
