Subject: [PATCH nf-next 0/3] netfilter: nft_bitwise: shift support
Date: Fri, 10 Jan 2020 12:33:09 +0000 [thread overview]
Message-ID: <20200110123312.106438-1-jeremy@azazel.net> (raw)
The connmark xtables extension supports bit-shifts. Add support for
shifts to nft_bitwise in order to allow nftables to do likewise, e.g.:
nft add rule t c oif lo ct mark set meta mark << 8 | 0xab
nft add rule t c iif lo meta mark & 0xff 0xab ct mark set meta mark >> 8
There are a couple of preliminary tidying-up patches first.
Jeremy Sowden (3):
netfilter: nf_tables: white-space fixes.
netfilter: bitwise: replace gotos with returns.
netfilter: bitwise: add support for shifts.
