Subject: [PATCH nf-next v2 00/10] netfilter: nft_bitwise: shift support
Date: Tue, 14 Jan 2020 21:29:08 +0000 [thread overview]
Message-ID: <20200114212918.134062-1-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
Changes since v1:
* more white-space fixes;
* move bitwise op enum to UAPI;
* add NFTA_BITWISE_OP and NFTA_BITWISE_DATA;
* remove NFTA_BITWISE_LSHIFT and NFTA_BITWISE_RSHIFT;
* add helpers for initializaing, evaluating and dumping different
types of operation.
