From 02833d1b381f468c8744f786061b36b7a4c2572a Mon Sep 17 00:00:00 2001 From: Andreas Henriksson Date: Mon, 2 Aug 2010 09:30:33 +0200 Subject: [PATCH] tc: make symbols loaded from tc action modules global. Fixes problems with xtables based MARK target ("ipt" module). When tc loads the "ipt" (xt) module it kept the symbols local, this made loading of libxtables not find the required struct. currently ipt/xt is the only tc action module. iproute2 never seem to do dlclose. hopefully the modules doesn't export more symbols then needed. In this situation hopefully the RTLD_GLOBAL flag won't hurt us. I've been using this patch in the Debian package of iproute for the last 3 weeks and noone has complained.
