From ad10a10567e243425d7be35a3d950709371fa048 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 14 Jan 2017 13:08:59 +0100 Subject: [PATCH] selinux: Use kcalloc() in policydb_index() Multiplications for the size determination of memory allocations indicated that array data structures should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software.
