Subject: [PATCH] misannotation in pppol2tp
Date: Thu, 26 Jul 2007 17:35:09 +0100	[thread overview]
Message-ID: <E1IE6Iv-0005Lj-N2@ZenIV.linux.org.uk> (raw)


Address of auto variable is not a userland pointer.  A good thing, too,
since if pppol2tp_tunnel_getsockopt() would _really_ get a userland pointer
as argument, it would be an instant roothole...
