Subject: [PATCH 07/12] lpfc: Fix coverity errors in fmdi attribute handling
Date: Mon, 27 Jan 2020 16:23:07 -0800 [thread overview]
Message-ID: <20200128002312.16346-8-jsmart2021@gmail.com> (raw)
In-Reply-To: <20200128002312.16346-1-jsmart2021@gmail.com>
Coverity reported a memory corruption error for the fdmi attributes
routines:
CID 15768 [Memory Corruption] Out-of-bounds access on FDMI
Sloppy coding of the fmdi structures. In both the lpfc_fdmi_attr_def
and lpfc_fdmi_reg_port_list structures, a field was placed at the start
of payload that may have variable content. The field was given an
arbitrary type (uint32_t). The code then uses the field name to derive
an address, which it used in things such as memset and memcpy. The
memset sizes or memcpy lengths were larger than the arbitrary type,
thus coverity reported an error.
Fix by replacing the arbitrary fields with the real field structures
describing the payload.
