Synopsis: bpf_filter() can leak kernel stack contents

State-Changed-From-To: open->feedback
State-Changed-By: drochner%NetBSD.org@localhost
State-Changed-When: Thu, 14 Jul 2011 12:51:19 +0000
State-Changed-Why:
contrary to OpenBSD (and libpcap), NetBSD checks accesses to scratch mem
in bpf_validate(), zeroing it should thus be unnecessary
ok to close?
