Subject: [PATCH v2 3/9] tproxy: added udp6_lib_lookup function
Date: Thu, 21 Oct 2010 12:47:09 +0200 [thread overview]
Message-ID: <20101021104709.5192.57640.stgit@este.odu> (raw)
In-Reply-To: <20101021104709.5192.31249.stgit@este.odu>
From: Balazs Scheidler <bazsi@balabit•hu>
Just like with IPv4, we need access to the UDP hash table to look up local
sockets, but instead of exporting the global udp_table, export a lookup
function.
