From f9c1bba3d392843f046d2ee27b4dfcec989d8a4b Mon Sep 17 00:00:00 2001 From: Marc Dionne Date: Fri, 11 May 2018 21:35:06 -0300 Subject: [PATCH] afs: Fix afs_find_server search loop The code that looks up servers by addresses makes the assumption that the list of addresses for a server is sorted. It exits the loop if it finds that the target address is larger than the current candidate. As the list is not currently sorted, this can lead to a failure to find a matching server, which can cause callbacks from that server to be ignored. Remove the early exit case so that the complete list is searched.
