File 0014-Set-RPC-related-rules-also-for-IPv6-bnc-1074933.patch of Package SuSEfirewall2.6458

From d5cdb9bab9cc750ae12492a4fff548ff7dd32d38 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Set RPC related rules also for IPv6 (bnc#1074933)

The dynamic rpcinfo based rules are not applied to ip6tables. This
commit changes the behaviour to apply rules with IP specific src/dst net
restriction only to those ipXtables, all other rules to both.

(cherry picked from commit ba922c27cf83aca77e3f5101f5a3af55f406776b)
