retitle 571634 xen-utils-common vif-common.sh still using --physdev-out, --state
found 571634 4.0.0-1
thanks

Hi,

That link to upstream patch in the last message is apparently broken,
a working one is:

http://xenbits.xen.org/hg/xen-unstable.hg/rev/b0fe8260cefa

but also more importantly for the current stable package:

http://xenbits.xen.org/hg/xen-4.0-testing.hg/rev/af7110f4f803

Because the state module is activated, conntrack kicks in, and eventually
a high amount of traffic will cause the following to happen on dom0:

Jun  9 09:24:45 crux kernel: [27998.532343] nf_conntrack: table full, dropping packet.
Jun  9 09:24:54 crux kernel: [28007.820634] nf_conntrack: table full, dropping packet.
Jun  9 09:24:54 crux kernel: [28007.820651] nf_conntrack: table full, dropping packet.

That could almost qualify as an excessive susceptibility to DoS, i.e. a security
issue.

Please fix both bugs in stable. TIA.
