From 3b5d4072035a87f85ffda6b155cbdd3bbc15deef Mon Sep 17 00:00:00 2001 From: Jacob Erlbeck Date: Fri, 24 Oct 2014 15:11:03 +0200 Subject: sgsn: Moved IMSI ACL management to sgsn_auth.c Currently the ACL code is located in sgsn_vty.c. This commit moves this to a new file sgsn_auth.c as a first step to make authorization more flexible in order to implement remote acquisition on subsciber data.
