From bb31e20bcd0d6d8112d9ec7f46b7e542a850e001 Mon Sep 17 00:00:00 2001 From: Benedict Wong Date: Wed, 13 Dec 2017 18:26:40 -0800 Subject: [PATCH 1/5] Add checks to ensure SPIs are not reused This change adds an additional check in CheckIpsecConfig to prevent users from using the same SPI twice. This allows for a more granular error message.
