Subject: RE: [PATCH v7 1/4] net/bnx2x: fix warnings about rte_memcpy lengths
Date: Thu, 9 Feb 2023 17:49:31 +0100 [thread overview]
Message-ID: <98CBD80474FA8B44BF855DF32C47DC35D87724@smartserver.smartshare.dk> (raw)
In-Reply-To: <20230116130724.50277-1-mb@smartsharesystems.com>
PING bnx2x maintainers. Care to review this bugfix, so it can be included in 23.03?
> From: Morten Brørup [mailto:mb@smartsharesystems.com]
> Sent: Monday, 16 January 2023 14.07
>
> Bugfix: The vlan in the bulletin does not contain a VLAN header, only
> the
> VLAN ID, so only copy 2 byte, not 4. The target structure has padding
> after the field, so copying 2 byte too many is effectively harmless.
> There is no need to backport this patch.
>
> Use RTE_PTR_ADD where copying arrays to the offset of a first field in
> a
> structure holding multiple fields, to avoid compiler warnings with
> decorated rte_memcpy.
