Subject: [dpdk-dev] [PATCH 2/2] net/bonding: fix oob access in "other" aggregator modes
Date: Thu, 21 Mar 2019 21:28:14 +0100	[thread overview]
Message-ID: <1553200094-5487-2-git-send-email-david.marchand@redhat.com> (raw)
Message-ID: <20190321202814.P8dW6YKx_R-DlT6JR-bM-dJfoQMjsN19HTbvBy-hmT8@z> (raw)
In-Reply-To: <1553200094-5487-1-git-send-email-david.marchand@redhat.com>

From: Zhaohui <zhaohui8@huawei.com>

slave aggregator_port_id is in [0, RTE_MAX_ETHPORTS-1] range.
If RTE_MAX_ETHPORTS is > 8, we can hit out of bound accesses on
agg_bandwidth[] and agg_count[] arrays.

Fixes: 6d72657ce379 ("net/bonding: add other aggregator modes")
