From c36f74e67fa12202dbcb4ad92c5ac844f9d36b98 Mon Sep 17 00:00:00 2001 From: Joshua Roys <joshua.roys@gtri.gatech.edu> Date: Wed, 24 Feb 2010 18:52:44 -0500 Subject: [PATCH] netlabel: fix export of SELinux categories > 127 This fixes corrupted CIPSO packets when SELinux categories greater than 127 are used. The bug occured on the second (and later) loops through the while; the inner for loop through the ebitmap->maps array used the same index as the NetLabel catmap->bitmap array, even though the NetLabel bitmap is twice as long as the SELinux bitmap.
