From 181dead3f13befe02769ef479bcbb51801b7fc4e Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Thu, 4 Oct 2007 16:27:07 +0000 Subject: Unique symbols 1/6 Give symbols of libxt matches unique names (1/3). Adds unique prefixes to all functions (most of them - especially the hook functions) so that debugging programs can unambiguously map a symbol to an address. Also unifies the names of the xtables_match/xtables_target structs, (based upon libxt_connmark.c/libip6t_*.c).
