From 55c79c9d91f1125c5ef97e3046dbad832b32cc10 Mon Sep 17 00:00:00 2001 From: "/C=DE/ST=Berlin/L=Berlin/O=Netfilter Project/OU=Development/CN=kaber/emailAddress=kaber@netfilter.org" Date: Thu, 20 Jul 2006 17:18:44 +0000 Subject: [PATCH] BUG: libiptc chain references bug (Jesper Brouer ) Correcting a chain references increment bug in libiptc. The bug lies in function iptc_delete_entry() / TC_DELETE_ENTRY. The problem is the construction of "r" the rule entry, that is used for comparison. The problem is that the function iptcc_map_target() increase the target chains references count. --- libiptc/libiptc.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/libiptc/libiptc.c b/libiptc/libiptc.c index 794904b..779df34 100644 --- a/libiptc/libiptc.c +++ b/libiptc/libiptc.c @@ -1519,6 +1519,14 @@ TC_DELETE_ENTRY(const IPT_CHAINLABEL chain, DEBUGP("unable to map target of rule for chain `%s'\n", chain); free(r); return 0; + } else { + /* iptcc_map_target increment target chain references + * since this is a fake rule only used for matching + * the chain references count is decremented again. + */ + if (r->type == IPTCC_R_JUMP + && r->jump) + r->jump->references--; } list_for_each_entry(i, &c->rules, list) { -- cgit v1.2.3
