tipc: add support for link state subscriptions
Low level topology information like TIPC link up/down is useful for
applications like teamd to make smarter failover decisions in a
HA cluster environment. Fetching logical link names through an ioctl
may hurt the eyes of some. Suggestions for a more elegant way of doing
this would be appreciated in that case. :)
v2:
-Properly based on net-next
-Off-list comments from Billie Alsup:
-Add a string length parameter to tipc_node_get_linkname
-Use TIPC_MAX_LINK_NAME definition instead of hardcoded
value in tipc_sioc_ln_req linkname
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
We add a new ioctl for AF_TIPC that can be used to fetch the
logical name for a link to a remote node on a given bearer. This
should be used in combination with link state subscriptions.
The logical name size limit definitions are moved to tipc.h, as
they are now also needed by the new ioctl.

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
ip netns exec netns1 ip addr add 192.168.0.249/24 broadcast 192.168.0.255 dev vxlan10

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
behavior.
Ran the netperf test with 200 stream for 1 min between two hosts with
4x1G trunk (xmit-lb mode with xmit-policy L3+4) before and after these

Intel Wired LAN Driver Updates

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
vlan_filter_enable() in ixgbe so that we can do the work directly in
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
the appropriate field in the VF info struct.

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
recent changes in the firmware. Also rearranges the "if netdev" logic
to prepare for handling non-netdev VSIs. Lastly rework the fdir
setup and tear down to use the newly created i40e_vsi_open() and
i40e_vsi_close(), which also fixes a memory leak of the FDIR queue
buffer info structs across a reset.

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?
