Subject: [PATCH nf-next 0/5] support for several expression in set elements
Date: Mon, 7 Dec 2020 19:16:46 +0100 [thread overview]
Message-ID: <20201207181651.18771-1-pablo@netfilter.org> (raw)
Hi,
This patchset extends nftables to support for several expressions
per set element.
So far, users can only specify either a counter or a ratelimit
per set element, this patchset allows for combining both.
This patchset adds an artificial cap for up to 2 expressions for set
elements which can be easily augmented later on by simply updating the
NFT_SET_EXPR_MAX definition.
Comments welcome, thanks.
Pablo Neira Ayuso (5):
netfilter: nftables: generalize set expressions support
netfilter: nftables: move nft_expr before nft_set
netfilter: nftables: generalize set extension to support for several
expressions
netfilter: nftables: add nft_expr_parse() helper function
netfilter: nftables: netlink support for several set element
expressions
