that we think to be important (meaning they fix critical

Patch 1 (by me) is preventing DAT from injecting replies received from the
mesh into the LAN
When a node running DAT receives an ARP request from the LAN for the
first time, it is likely that this node will request the ARP entry
through the distributed ARP table (DAT) in the mesh.
Once a DAT reply is received the asking node must check if the MAC
address for which the IP address has been

For designs where EEPROMs are not connected to PCI Yukon2
chips we need to get the MAC address from the firmware.
Add a module parameter called 'mac_address' for this. It
will be used if no DT node can be found and the B2_MAC
register holds an invalid value.

Also, you probably want a WARN_ON(in_nmi()) there, this function is
_NOT_ NMI safe.
we check that very early on:

Hi folks,
I have written an extremely simple reproducer. Xen 4.5.1. Linux 4.1.3.
Config attached. Reproducer attached. Makefile attached.
It results in the COMPLETE lockup of the system when it receives a
network packet over the Xen PV network interface.
The lockup is 100% reliable. As in the
There is a race condition in store_rps_map that allows jump label
count in rps_needed to go below zero. This can happen when
concurrently attempting to set and a clear map.
Scenario:
1. rps_needed count is zero
2. New map is assigned by setting thread, but rps_needed count _not_ yet

If a user passes in a table for new routes use that table for nexthop
lookups. Specifically, this solves the case where a connected route does
not exist in the main table, but only another table and then a subsequent
route is added with a next hop using the connected route. ie.,
$ ip route ls
In the context of internet scale routing a requirement that always comes
up is the need to partition the available routing tables into disjoint
routing planes. A specific use case is the multi-tenancy problem where
each tenant has their own unique routing tables and in the very least

Allow user to create a vrf device and specify its table binding.

As with ingress use the index of VRF master device for route lookups on
egress. However, the oif should only be used to direct the lookups to a

This driver borrows heavily from IPvlan and teaming drivers.
Routing domains (VRF-lite) are created by instantiating a VRF master

On ingress use index of VRF master device for route lookups if real device

The intent of the VRF device is to leverage the existing SO_BINDTODEVICE
as a means of creating L3 domains. Since sockets are expected to be bound
to the VRF device the index of the master device needs to be used for
socket lookups.
