From 328fa34f8ac18d30fec00c7c5f59a05850f631a5 Mon Sep 17 00:00:00 2001 From: "a.sreekumar" Date: Fri, 28 May 2021 11:40:37 +0100 Subject: Fixing issues around policy deployment in APEX Following items are fixed. 1) When in PASSIVE state, any policiesToBeUndeployed received in PDP_UPDATE message are not handled. 2) APEX policy deployment fails when policiesToBeUndeployed and policiesToBeDeployed come together in PDP_UPDATE message from PAP. 3) Improve response messages after deployment/undeployment.
