Subject: [dpdk-stable] [PATCH v4 12/19] net/ena: terminate devargs allowed keys with null
Date: Tue, 11 May 2021 08:45:47 +0200	[thread overview]
Message-ID: <20210511064554.10656-13-mk@semihalf.com> (raw)
In-Reply-To: <20210511064554.10656-1-mk@semihalf.com>

As the documentation of rte_kvargs_parse() states, the valid_keys
argument must be NULL terminated. Lack of this feature may cause
segmentation fault if the passed devarg will be different then the
supported value.

Fixes: 8a7a73f26cc9 ("net/ena: support large LLQ headers")
Cc: stable@dpdk.org
