From b848ff5de4e974dd9e471fc0888ea990a86e34af Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Fri, 28 Nov 2014 21:20:59 +0100 Subject: datatype: relax datatype check in integer_type_parse() Otherwise parsing with basetypes doesn't work. Now nft displays an error when the symbolic constant is not correct: :1:29-31: Error: Could not parse conntrack state add rule test test ct state xxx accept ^^^ Use .sym_tbl instead and default on the symbol_constant_parse() function from the ethertype and pkttype, this simplifies the code and (more importantly) it avoids a breakage after the change in integer_type_parse().
