From 0f2fc313079fff15de2eadbd0fdcbee8320072f2 Mon Sep 17 00:00:00 2001 From: Luka Perkov Date: Tue, 10 May 2016 22:36:35 +0000 Subject: [PATCH] xtables-addons: Fix Lua packet script implementation lua_packet_segment parameter start has type char pointer; in function lua_tg it's assigned an uint16 value generating compiler warnings obviously indicating posssible seg fault problems. Fix the issue by using the correct skb functions so the parameter points to the position inside the sk_buff Signed-off-by: Hans Dedecker Signed-off-by: Stijn Cleynhens SVN-Revision: 49331 --- .../patches/201-fix-lua-packetscript.patch | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/package/network/utils/xtables-addons/patches/201-fix-lua-packetscript.patch b/package/network/utils/xtables-addons/patches/201-fix-lua-packetscript.patch index 06a4a1739a..ebc952bca3 100644 --- a/package/network/utils/xtables-addons/patches/201-fix-lua-packetscript.patch +++ b/package/network/utils/xtables-addons/patches/201-fix-lua-packetscript.patch @@ -13,6 +13,21 @@ { uint32_t verdict; lua_packet_segment *p; +@@ -88,11 +88,11 @@ lua_tg(struct sk_buff *pskb, const struc + /* push the lua_packet_segment as a parameter */ + p = (lua_packet_segment *)lua_newuserdata(L, sizeof(lua_packet_segment)); + if (pskb->mac_header) +- p->start = pskb->mac_header; ++ p->start = skb_mac_header(pskb); + else if (pskb->network_header) +- p->start = pskb->network_header; ++ p->start = skb_network_header(pskb); + else if (pskb->transport_header) +- p->start = pskb->transport_header; ++ p->start = skb_transport_header(pskb); + p->offset = 0; + p->length = (unsigned long)pskb->tail - (unsigned long)p->start; + p->changes = NULL; @@ -208,16 +208,16 @@ static bool load_script_into_state(uint3 * some workqueue initialization.
