Subject: [PATCH AUTOSEL 4.19 110/671] RDMA/qedr: Fix out of bounds index check in query pkey
Date: Thu, 16 Jan 2020 11:45:41 -0500	[thread overview]
Message-ID: <20200116165502.8838-110-sashal@kernel.org> (raw)
In-Reply-To: <20200116165502.8838-1-sashal@kernel.org>

From: Gal Pressman <galpress@amazon.com>

[ Upstream commit dbe30dae487e1a232158c24b432d45281c2805b7 ]

The pkey table size is QEDR_ROCE_PKEY_TABLE_LEN, index should be tested
for >= QEDR_ROCE_PKEY_TABLE_LEN instead of > QEDR_ROCE_PKEY_TABLE_LEN.
