e2613dc860 iproute2: add support for IFLA_NET_NS_PID in ip link
Hi Stephen,

I resend you this patch once more. This time I updated the documentation
too (may be that was the reason why you didn't take it before?).

Please tell me if there are other things missing in this patch
It applies on iproute2 git tree.

Regards,
Benjamin

Description:
------------

This patch adds support for the IFLA_NET_NS_PID type. It is used to
move network devices between network namespaces.

The syntax is:
ip link set DEVICE netns PID

PID is the pid of a process in the target network namespace.

(Daniel Lezcano is the original author).

909dfe2c7e iplink_parse() routine
This routine parses CLI attributes, describing generic link
parameters such as name, address, etc.

This is mostly copy-pasted from iplink_modify().

It seems it fails to properly detect that your kernel is missing
RTM_NEWLINK support. Apparently the reason is that the kernels
I tested with return a different error in this situation.

Indentation fixed, same change for the non-ioctl case, use invarg.
While I'm at it I also fixed the error message for "name too long",
*argv is NULL at this point.

ba371d9890 don't allow "" for device name
If a zero-length string is given, it is not rejected by
netlink in kernel so catch it at command line.

7b5657545d The ip(8) command has a bug when dealing with IPoIB link layer
addresses. Specifically it does not correctly handle the addition of
new entries in the neighbor/arp table. For example, this command will
fail:

ip neigh add 192.168.0.138 lladdr
00:00:04:04:fe:80:00:00:00:00:00:00:00:01:73:00:00:00:8a:91 nud
permanent dev ib0

An IPoIB link layer address is 20-bytes (see
http://www.ietf.org/internet-drafts/draft-ietf-ipoib-ip-over-infiniband-09.txt,
section 9.1.1).

The command line parsing code expects link layer addresses to be a
maximum of 16-bytes. Addresses over 16-bytes are truncated.
