From 8a499c23feaa3174e1c35276481ff1094508bec3 Mon Sep 17 00:00:00 2001 From: Beilei Xing Date: Tue, 5 Jul 2016 14:15:40 +0800 Subject: [PATCH] examples/tep_term: fix port id check Coverity reported lots of out-of-bounds in function vxlan_link, these issues should happen when index port_id evaluates to 2, cause size of arrays is 2 in structure. Fix this issue by modifying judgement condition, make sure port_id is less than 2.
