From ff235f51a138fc61e1a22dcb8b072d9c78c2a8cc Mon Sep 17 00:00:00 2001 From: Paul Davies C Date: Thu, 21 Nov 2013 08:14:03 +0530 Subject: audit: Added exe field to audit core dump signal log Currently when the coredump signals are logged by the audit system, the actual path to the executable is not logged. Without details of exe, the system admin may not have an exact idea on what program failed. This patch changes the audit_log_task() so that the path to the exe is also logged. This was copied from audit_log_task_info() and the latter enhanced to avoid disappearing text fields.
