From 5842ce7b120c65624052a8da04460d35b26caac0 Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 4 Dec 2024 07:46:30 +0000 Subject: rxrpc: Fix handling of received connection abort [ Upstream commit 0e56ebde245e4799ce74d38419426f2a80d39950 ] Fix the handling of a connection abort that we've received. Though the abort is at the connection level, it needs propagating to the calls on that connection. Whilst the propagation bit is performed, the calls aren't then woken up to go and process their termination, and as no further input is forthcoming, they just hang. Also add some tracing for the logging of connection aborts.
