From c566ab68af7da089ae2b0ff664d02a93a0647584 Mon Sep 17 00:00:00 2001 From: Ian Jackson Date: Wed, 19 Feb 2014 14:03:29 +0000 Subject: [PATCH] libxl: Fix error path in libxl_device_events_handler libxl_device_events_handler would fail to call AO_ABORT if it failed; instead it would simply return rc. (This leaves the egc etc. from the now-abolished stack frame potentially live, and leaves the ctx locked.) In xl, this is of no consequence, because xl will immediately exit in this situation. This is very likely to be true in any other callers (of which we don't know of any, anyway).
