There are a few preliminary housekeeping patches. Actually, this batch goes in the direction of adding the basic lshift/right support. # nft --debug=netlink add rule x y tcp dport set tcp dport lshift 1 ip x y [ meta load l4proto => reg 1 ] [ cmp eq reg 1 0x00000006 ] [ payload load 2b @ transport header + 2 => reg 1 ] [ byteorder reg 1 = ntoh(reg 1, 2, 2) ] [ bitwise reg 1 = ( reg 1 << 0x00000001 ) ] [ payload write reg 1 => 2b @ transport header + 2 csum_type 1 csum_off 16 csum_flags 0x0 ] I'm applying patches 1, 2, 3, 4, 7 and 8. Regarding patch 5, it would be good to restore the parens when listing. Patch 6, I guess it will break something else. Did you run tests/py to check this? Patch 9, I'm skipping until 5 and 6 are sorted out. Thanks.
