vxlan: add x-netns support

This patch allows to switch the netns when packet is encapsulated or
decapsulated.
The vxlan socket is openned into the i/o netns, ie into the netns where
encapsulated packets are received. The socket lookup is done into this netns to
find the corresponding vxlan tunnel. After decapsulation, the packet is
injecting into the corresponding interface which may stand to another netns.

When one of the two netns is removed, the tunnel is destroyed.

Configuration example:
ip netns add netns1
ip netns exec netns1 ip link set lo up
ip link add vxlan10 type vxlan id 10 group 239.0.0.10 dev eth0 dstport 0
ip link set vxlan10 netns netns1

The aggresive load balancing causes packet re-ordering as active
flows are moved from a slave to another within the group. Sometime
this aggresive lb is not necessary if the preference is for less
re-ordering. This parameter if used with value "0" disables
this dynamic flow shuffling minimizing packet re-ordering. Of course
the side effect is that it has to live with the static load balancing
that the hashing distribution provides. This impact is less severe if
the correct xmit-hashing-policy is used for the tlb setup.

The default value of the parameter is set to "1" mimicing the earlier

Jacob converts the ixgbe low_water into an array which allows the
algorithm to output different values for different TCs and we can
distinguish between them.  Removes vlan_filter_disable() and

set_rx_mode().  Changes the setting of multicast filters only when
the interface is not in promiscuous mode for multicast packets in
ixgbe.  Improves MAC filter handling by adding mac_table API based
on work done for igb, which includes functions to add/delete MAC
filters.

Mark changes register reads in ixgbe to an out-of-line function since
register reads are slow.

Emil provides a ixgbevf patch to update the driver description since
it supports more than just 82599 parts now.

David provides several cleanup patches for e1000e which resolve some
checkpatch issues as well as changing occurrences of returning 0 or 1 in
bool functions to returning true false or true.

Carolyn provides several cleanup patches for igb which fix checkpatch
warnings.

Mitch provides a fix for i40evf where the driver would correctly allow
the virtual function link state to be controlled by 'ip set link', but
would not report it correctly back.  This is fixed by filling out

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e and i40evf.

Greg provides two patches for i40e, the first adds the netdev ops to support
the addition of static FDB entries in the physical function (PF) MAC/VLAN
filter table so that the virtual functions (VFs) can communicate with
bridged virtual Ethernet ports such as those provided by the virtio
driver.  The second is to fix an issue where the assignment of a port
VLAN after it is already up and running requires the VF driver to be
reloaded, so print a message warning the host administrator about the
need to reload the VF driver.  In addition, knock the VF offline so that
it does not continue to receive traffic not on the port VLAN assigned to
it.

Jesse provides a patch for i40e and i40evf to unhide and enable the
PREFENA field in the receive host memory cache (RX-HMC) for best
performance.

Mitch provides a i40e patch to implement the net device op for Tx
bandwidth setting.

Catherine removes a firmware workaround that is no longer needed with
the latest firmware for i40e.  She also provides some minor cleanups
as well bumps the driver versions.

Anjali provides a fix for i40e displaying IPv4 flow director filters
which needed additional information to be communicated up above in
order for it to be displayed correctly.

Shannon adds tracking of the NVM busy state so that the driver won't
allow a new NVM update command until a completion event is received
from the current update.  Updates the admin queue API to reflect

audit: implement multicast socket for journald

This is a patch set Eric Paris and I have been working on to add a restricted
capability read-only netlink multicast socket to kernel audit to enable
userspace clients such as systemd/journald to receive audit logs, in addition
to the bidirectional auditd userspace client.

Currently, auditd has the CAP_AUDIT_CONTROL and CAP_AUDIT_WRITE capabilities
(but uses CAP_NET_ADMIN).  The CAP_AUDIT_READ capability will be added for use
by read-only AUDIT_NLGRP_READLOG multicast group clients to the kaudit
subsystem.  This will remove the dependence on CAP_NET_ADMIN for the multicast
read-only socket.

Patches 1-3 provide a way for per-protocol bind functions to
signal an error and to be able to clean up after themselves.

The first netfilter cleanup patch has already been accepted by a netfilter
maintainer, though I don't see it upstream yet, so it is included for
completeness.

The second patch adds the per-protocol bind function return code to signal to
the netlink code that no further processing should be done and to undo the work
already done.
V1: This rev fixes a bug introduced by flattening the code in the last posting.
*V2: This rev moves the per-protocol bind call above the socket exposure call
and refactors out the unbind procedure.

The third provides a way per protocol to undo bind actions on DROP.

Patches 4-6 implement the audit multicast socket with capability checking.

The fourth patch adds the bind function capability check to multicast join
requests for audit.

The fifth patch adds the audit log read multicast group.  An assumption has
been made that systemd/journald reside in the initial network namespace.  This
could be changed to check the actual network namespace of systemd/journald
should this assumption no longer be true since audit now supports all network
namespaces.  This version of the patch now directly sends the broadcast when
the packet is ready rather than waiting until it passes the queue.

The sixth checks if any clients actually exist before sending.

Since the net tree is busier than the audit tree, conflicts are more likely and
the audit patches depend on the net patches, it is proposed to have the net
tree carry this entire patchset for 3.16.  Are the net maintainers ok with this?

we fragment a TSO packet before retransmit, or in TLP path.

retransmit.
Original packet is in a queue and will eventually leave the host.

====================
purge tipc_net_lock

Now tipc routing hierarchy comprises the structures 'node', 'link'and
'bearer'. The whole hierarchy is protected by a big read/write lock,
tipc_net_lock, to ensure that nothing is added or removed while code
is accessing any of these structures. Obviously the locking policy
makes node, link and bearer components closely bound together so that
their relationship becomes unnecessarily complex. In the worst case,
such locking policy not only has a negative influence on performance,
but also it's prone to lead to deadlock occasionally.

In order o decouple the complex relationship between bearer and node
as well as link, the locking policy is adjusted as follows:

- Bearer level
  RTNL lock is used on update side, and RCU is used on read side.
  Meanwhile, all bearer instances including broadcast bearer are
  saved into bearer_list array.

- Node and link level
  All node instances are saved into two tipc_node_list and node_htable
  lists. The two lists are protected by node_list_lock on write side,
  and they are guarded with RCU lock on read side. All members in node
  structure including link instances are protected by node spin lock.

- The relationship between bearer and node
  When link accesses bearer, it first needs to find the bearer with
  its bearer identity from the bearer_list array. When bearer accesses
  node, it can iterate the node_htable hash list with the node address
  to find the corresponding node.

In the new locking policy, every component has its private locking
solution and the relationship between bearer and node is very simple,
that is, they can find each other with node address or bearer identity

Commit a21a584d6720ce349b05795b9bcfab3de8e58419 (tipc: fix neighbor
detection problem after hw address change) introduces a race condition
involving tipc_disc_delete() and tipc_disc_add/remove_dest that can
cause TIPC to dereference the pointer to the bearer discovery request
structure after it has been freed since a stray pointer is left in the
bearer structure.

In order to fix the issue, the process of resetting the discovery
request handler is optimized: the discovery request handler and request
buffer are just reset instead of being freed, allocated and initialized.
As the request point is always valid and the request's lock is taken
while the request handler is reset, the race doesn't happen any more.

Currently on both paths of message transmission and reception, the
read lock of tipc_net_lock must be held before bearer is accessed,
while the write lock of tipc_net_lock has to be taken before bearer
is configured. Although it can ensure that bearer is always valid on
the two data paths, link and bearer is closely bound together.

So as the part of effort of removing tipc_net_lock, the locking
policy of bearer protection will be adjusted as below: on the two
data paths, RCU is used, and on the configuration path of bearer,
RTNL lock is applied.

Now RCU just covers the path of message reception. To make it possible
to protect the path of message transmission with RCU, link should not
use its stored bearer pointer to access bearer, but it should use the
bearer identity of its attached bearer as index to get bearer instance
from bearer_list array, which can help us decouple the relationship
between bearer and link. As a result, bearer on the path of message
transmission can be safely protected by RCU when we access bearer_list
