Subject: [PATCH 4.4 26/34] bnxt_en: Fix the Invalid VF id check in bnxt_vf_ndo_prep routine.
Date: Fri, 2 Mar 2018 09:51:22 +0100 [thread overview]
Message-ID: <20180302084437.693698886@linuxfoundation.org> (raw)
In-Reply-To: <20180302084435.842679610@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>
[ Upstream commit 78f300049335ae81a5cc6b4b232481dc5e1f9d41 ]
In bnxt_vf_ndo_prep (which is called by bnxt_get_vf_config ndo), there is a
check for "Invalid VF id". Currently, the check is done against max_vfs.
However, the user doesn't always create max_vfs. So, the check should be
against the created number of VFs. The number of bnxt_vf_info structures
that are allocated in bnxt_alloc_vf_resources routine is the "number of
requested VFs". So, if an "invalid VF id" falls between the requested
number of VFs and the max_vfs, the driver will be dereferencing an invalid
pointer.
Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")
