From 7d7587db0d7fd1138f2afcffdc46a8e15630b944 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 12 Mar 2020 21:40:06 +0000 Subject: afs: Fix client call Rx-phase signal handling Fix the handling of signals in client rxrpc calls made by the afs filesystem. Ignore signals completely, leaving call abandonment or connection loss to be detected by timeouts inside AF_RXRPC. Allowing a filesystem call to be interrupted after the entire request has been transmitted and an abort sent means that the server may or may not have done the action - and we don't know. It may even be worse than that for older servers.
