e34d3dcce2 ip: use rtnelink to manage mroute
mroute was using /proc/net/ip_mr_[vif|cache] to display mroute entries. Hence,
only RT_TABLE_DEFAULT was displayed and only IPv4.
With rtnetlink, it is possible to display all tables for IPv4 and IPv6. The output
format is kept. Also, like before the patch, statistics are displayed when user specify
the '-s' argument.

The patch also adds the support of 'ip monitor mroute', which is now possible.

1556e29d3c add DOVE extensions for iproute2
This patch adds a new flag to iproute2 for vxlan devices to enable
DOVE features. It also adds support for L2 and L3 switch lookup miss
netlink messages to "ip monitor".

Changes since v2: fix merge conflict
Changes since v1:
	- split "dove" flag into separate feature flags:
		- "proxy" for ARP reduction
		- "rsc" for route short circuiting
		- "l2miss" for L2 switch miss notifications
		- "l3miss" for L3 switch miss notifications

This functionality is required by checkpoint-restore project. Since the

93b7986345 iproute: Add route showdump command (v2)
Some time ago the save+restore commands were added to ip route (git
id f4ff11e3, Add ip route save/restore). These two save the raw rtnl
stream into a file and restore one (reading it from stdin).

The problem is that there's no way to get the contents of the dump
file in a human readable form. The proposal is to add a command that
reads the rtnl stream from stdin and prints the data in a way the
usual "ip route list" does?

changes since v1:

* Take the magic at the beginning of the dump file into account
* Check for stdin (the dump is taken from) is not a tty

af9d406f99 Fix regression with 'ip address show'
`ip a s` no longer shows addresses since 3.4.0 works, but 3.5.0,

the simple test case:
make clean && make -j -s && ./ip/ip a s lo

before that change, i would get:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever

but after, i now get:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

seems like the bug was introduced in the middle of that patch:

-	if (filter.family != AF_PACKET) {
+	if (filter.family && filter.family != AF_PACKET) {
+		if (filter.oneline)
+			no_link = 1;
+
 		if (rtnl_wilddump_request(&rth, filter.family, RTM_GETADDR) < 0) {
 			perror("Cannot send dump request");
 			exit(1);

if i revert the change to the if statement there, `ip a s` works for me again.

ae5555d334 ipl2tp: allow setting session interface name
Hi,

I've attached a trivial patch for iproute2 to allow naming interfaces
created with "ip l2tp add session".

I believe patches should go through the netdev mailing list but this
patch is so small I figured that would just add noise. Hope that's OK.

Originally I thought I would need a bigger patch and was going to take a
stab at implementing something like

ip l2tp add tunnel L2TP_TUNNEL_ARGS
ip link add name NAME  [ LINK_OPTS ] type l2tp L2TP_SESSION_ARGS

(a better interface IMHO) but all the code was there already, all that I
needed to add was option parsing.

Thanks,

João Valverde

7397944de6 ip: fix exit codes
Alternative fix to problem reported by: Bin Li
The issue is came from https://bugzilla.novell.com/show_bug.cgi?id=681952.

In any previous version (since suse ... 10.0?), ip addr add always returned
the error code 2 in case the ip address is already set on the interface:

    inet 172.16.2.3/24 brd 172.16.2.255 scope global bond0
RTNETLINK answers: File exists
2

On 11.4, it returns the exit code 254:

    inet 172.16.1.1/24 brd 172.16.1.255 scope global eth0
RTNETLINK answers: File exists
254

This of course causes ifup to return an error in this quite common case..

21a5a6b378 iproute2: fix changing of ip6ip6 tunnel parameters
When changing ip6ip6 parameters (ip -6 tun change), ip passes zeroed
struct ip6_tnl_parm to the kernel. The kernel then tries to change all of
the tunnel parameters to the passed values, including zeroing of local and
remote address. This fails (-EEXIST in net/ipv6/ip6_tunnel.c:ip6_tnl_ioctl).

For other tunnel types, ip fetches the current parameters first and applies
the required changes on top of them. This patch applies the same code as in
ip/iptunnel.c to ip/ip6tunnel.c.

See http://bugzilla.redhat.com/730627 for the original bug report.

0dc34c7713 iproute2: Add processless network namespace support
The goal of this code change is to implement a mechanism such that it is
simple to work with a kernel that is using multiple network namespaces
at once.

This comes in handy for interacting with vpns where there may be rfc1918
address overlaps, and different policies default routes, name servers
and the like.

Configuration specific to a network namespace that would ordinarily be
stored under /etc/ is stored under /etc/netns/<name>.  For example if
the dns server configuration is different for your vpn you would create
a file /etc/netns/myvpn/resolv.conf.

File descriptors that can be used to manipulate a network namespace can
be created by opening /var/run/netns/<NAME>.

This adds the following commands to iproute.
ip netns add NAME
ip netns delete NAME
ip netns monitor
ip netns list
ip netns exec NAME cmd ....
ip link set DEV netns NAME

ip netns exec exists to cater the vast majority of programs that only
know how to operate in a single network namespace.  ip netns exec
changes the default network namespace, creates a new mount namespace,
remounts /sys and bind mounts netns specific configuration files to
their standard locations.

cbec021913 xfrm: Update documentation
The ip(8) man page and the "ip xfrm [ XFRM-OBJECT ] help" command output
are updated to include missing options, fix errors, and improve grammar.
There are no functional changes made.

The documentation for the ip command has many different meanings for the
same formatting symbols (which really needs to be fixed). This patch makes
consistent use of brackets [ ] to indicate optional parameters, pipes | to
mean "OR", braces { } to group things together, and dashes - instead of
underscores _ inside of parameter names. The parameters are listed in the
order in which they are parsed in the source code.

There are several parameters and options that are still not mentioned or
need to be described more thoroughly in the "COMMAND SYNTAX" section of
the ip(8) man page. I would appreciate help from the developers with this.
