Subject: [PATCH nft v3 07/10] mnl: round up the map data size too
Date: Tue, 17 Dec 2019 12:27:10 +0100 [thread overview]
Message-ID: <20191217112713.6017-8-fw@strlen.de> (raw)
In-Reply-To: <20191217112713.6017-1-fw@strlen.de>
Same as key: if the size isn't divisible by BITS_PER_BYTE, we need to
round up, not down.
Without this, you can't store vlan ids in a map, as they are truncated
to 8 bit.
