Subject: [dpdk-dev] [PATCH] lib/librte_pipeline:fix the array index out of bound
Date: Wed, 23 Aug 2017 15:05:32 +0800 [thread overview]
Message-ID: <1503471932-22577-1-git-send-email-xie.rongqiang@zte.com.cn> (raw)
In function rte_pipeline_compute_masks(), the value pos equal
p->entries[i]->action,type constraint p->entries[i]->action is
