Subject: expression: constant range is not a singleton
X-Git-Tag: v1.1.4~40
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=674cd951ee642650586a719fda9f5e8c5fcab999;p=thirdparty%2Fnftables.git

expression: constant range is not a singleton

Remove the EXPR_F_SINGLETON flag in EXPR_RANGE_VALUE so it can be used
in maps.

expr_evaluate_set() does not toggle NFT_SET_INTERVAL for anonymous sets
because a singleton is assumed to be place, leading to this BUG:

 BUG: invalid data expression type range_value
 nft: src/netlink.c:577: netlink_gen_key: Assertion `0' failed.
