Subject: [PATCH nf-next v2 00/10] netfilter: nft_bitwise: shift support
Date: Tue, 14 Jan 2020 21:29:08 +0000
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.

Jeremy Sowden (10):
  netfilter: nf_tables: white-space fixes.
  netfilter: bitwise: remove NULL comparisons from attribute checks.
  netfilter: bitwise: replace gotos with returns.
  netfilter: bitwise: add NFTA_BITWISE_OP netlink attribute.
  netfilter: bitwise: add helper for initializing boolean operations.
  netfilter: bitwise: add helper for evaluating boolean operations.
  netfilter: bitwise: add helper for dumping boolean operations.
  netfilter: bitwise: only offload boolean operations.
  netfilter: bitwise: add NFTA_BITWISE_DATA attribute.
  netfilter: bitwise: add support for shifts.
