tv_usec is "suseconds_t" which is apparently usually
a signed long, but sometimes not....
Change the printf modifier to use signed and
cast the tv_usec to long in case it's not already long.

Use IFLA_AF_SPEC nested attributes to lookup bridge mode and when
doing strcmp() check for equality.

These appear to be typos from the original commit,

commit 64108901
Author: Vlad Yasevich <vyasevic@redhat.com>

    bridge: Add support for setting bridge port attributes

Also set flags to BRIDGE_FLAGS_SELF instead of using OR operation.
This allows setting the bridge mode when not being used with a
master device.

To allow setting both master and self devices simultaneously we
will need to add a {self|master} field similar to fdb commands.
For now the command sets are mutually exclusive as noted in the
original commit.

With this patch 'bridge link set' works now,

# ./bridge/bridge link set dev veth1 cost 3
# ./bridge/bridge link show
10: veth1 state UP : <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master bridge0 state forwarding priority 3 cost 3

This is now possible, because the dump function has been added in kernel.
Note that IPv4 and IPv6 entries are displayed.

Before this patch, only all entries were displayed.

Example:
$ ip netconf
ipv4 dev lo forwarding on rp_filter off mc_forwarding 0
ipv4 dev eth0 forwarding on rp_filter off mc_forwarding 1
ipv4 all forwarding on rp_filter off mc_forwarding 1
ipv4 default forwarding on rp_filter off mc_forwarding 0
ipv6 dev lo forwarding on mc_forwarding 0
ipv6 dev eth0 forwarding on mc_forwarding 0
ipv6 all forwarding on mc_forwarding 0

For later ss change.

This change shifts burden onto the users to choose the UDP port value.
Kernel default value is incorrect UDP port 5287 but now there is
an official assigned port for VXLAN.

The kernel can't change because of legacy compatibility
but new deployments should not use the legacy port value.

This patch allows setting the "NTF_ROUTER" flag in VXLAN forwarding table
entries to enable L3 switching for router destinations while still allowing
L2 redirection appliances for non-router MAC destinations.

iproute2 patch to generalize VXLAN forwarding tables

This is the iproute2 support allowing an administrator to specify alternate

Add ability to set UDP destination port on a per device basis.
If no port is assigned, the default IANA assigned port will be used.
If you want the kernel default value, then use port 0.

Source port range option is now called 'srcport', to avoid
confusion. The old option syntax is accepted for compatiablity.

This patch adds support for tokenized IIDs, that enable
administrators to assign well-known host-part addresses
to nodes whilst still obtaining global network prefix
from Router Advertisements. This is the iproute2 part for
the kernel patch f53adae4eae5 (``net: ipv6: add tokenized
interface identifier support'').

Example commands with iproute2:

Setting a device token:
  # ip token set ::1a:2b:3c:4d/64 dev eth1

Getting a device token:
  # ip token get dev eth1
  token ::1a:2b:3c:4d dev eth1

Listing all tokens:
  # ip token list  (or: ip token)
  token :: dev eth0
  token ::1a:2b:3c:4d dev eth1

Hello!

I'm attaching a patch [1] "Feed GCC 4.8.0 against new warning that is

Subject: [PATCH] Feed GCC 4.8.0 against new warning that is shipped with
 -Wall: -Wsizeof-pointer-memaccess.

In trying to build on a RHEL6.3 I ran into several build issues that are
addressed in this patch.

The first is that xtables_merge_options only has 3 parameters.  It appears
this is how this code was originally.  As such for the case where the version
is less than 6 I am assuming it would be correct to maintain the original
setup that only had 3 parameters being passed instead of 4.

I also ran into an issue with the define for __ALIGN_KERNEL not being present.
I believe this may be due to the fact that __ALIGN_KERNEL was moved into a
separate header from ALIGN after the UAPI changes.  In order to just cover all
of the bases I have moved the main definition for the macros into
__ALIGN_KERNEL_MASK and __ALIGN_KERNEL and if ALIGN is also needed then it is
just a direct redefine to __ALIGN_KERNEL.
