From 2a4d05a4e38b84cf287bb2d2266c07b6f10c9dee Mon Sep 17 00:00:00 2001 From: Nick Kralevich Date: Tue, 1 Jul 2014 10:57:16 -0700 Subject: implement LOG_EVENT_STRING Implement LOG_EVENT_STRING, so that native code can create new event log entries. This is needed to support logging SELinux denials to the event log.
