From 9b58da986680a92b350f02cd31ff64f30fecd07c Mon Sep 17 00:00:00 2001 From: Bill Parker Date: Wed, 17 Jul 2013 15:30:35 -0700 Subject: Fix bug 10025 - Lack of Sanity Checking in calls to malloc()/calloc(). In reviewing various files in Samba-4.0.7, I found a number of instances where malloc()/calloc() were called without the checking the return value for a value of NULL, which would indicate failure. (NB. The changes needed to ccan, iniparser, popt and heimdal will be reported upstream, not patched inside Samba).
