src: evaluate: support prefix expression in statements
Currently nft dumps core when it encounters a prefix expression as part of a statement, e.g. iifname ens3 snat to 10.0.0.0/28 yields: BUG: unknown expression type prefix nft: netlink_linearize.c:688: netlink_gen_expr: Assertion `0' failed. This assertion is correct -- we can't linearize a prefix because kernel doesn't know what that is. For LHS prefixes, they get converted to a binary 'and' such as '10.0.0.0 & 255.255.255.240'. For RHS, we can do something similar and convert them into a range. snat to 10.0.0.0/28 will be converted into: iifname "ens3" snat to 10.0.0.0-10.0.0.15 Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1187 Signed-off-by: Florian Westphal <fw@strlen.de> Acked-by: Pablo Neira Ayuso <pablo@netfilter.org>
