Subject: [PATCH] ixgbevf: off by one in ixgbevf_ipsec_tx()
Date: Wed, 19 Sep 2018 13:35:29 +0300	[thread overview]
Message-ID: <20180919103529.GC9238@mwanda> (raw)

The ipsec->tx_tbl[] array has IXGBE_IPSEC_MAX_SA_COUNT elements so the >
should be a >=.

Fixes: 0062e7cc955e ("ixgbevf: add VF IPsec offload code")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
