Put in sanitized 2.6.28 headers

Go back to original address parsing for compatability, but
document it and add more stringent checking.

Handle 10/8 as 10.0.0.0/8 and check for bogus values like 256/8.
This is a comprimise between original iproute2 parsing and standard BSD
parsing of abbreviated IPV4 addresses.

Hello Rafael Almeida.

I noticed your patch adding DESTDIR support in the latest iproute2 release.
Much appreciated! Soon the debian packages might be able to move to actually
using "make install" rather then it's own installation procedure when
building packages. I've noticed something that will break though....

Debian packages usually sets DESTDIR=debian/tmp/ and packages the contents
of that directory as if it where the root file system. This will break
the /usr/lib/{tc,ip}/ module loading, because they DESTDIR (/usr) will be
/whatever-the-build-path-was/debian/tmp/lib/{tc,ip}/.
I beleive others usually call this the LIBDIR to make the separation between
DISTDIR being the (possibly temporary) place things are put when build is
done, and LIBDIR (and others) are used for actual runtime paths.

I'm attaching a patch that I think fixes this, but would be really happy if
you could have a look at to verify I'm not screwing something up.

The patch below makes the "Nothing to flush" only visible when show
statistics flag is given, and then only to stdout rather then stderr.

$ sudo ./ip/ip -s addr flush dev skif
Nothing to flush.
$ sudo ./ip/ip addr flush dev skif

Apparently inet_pton doesn't support abbreviated/shortened/classful
ipv4 addresses at all, but inet_aton does.
Since the function only deals with AF_INET anyway maybe using
inet_aton "to increse backwards compatability" (please those
who still want to use the format) could be considered?
(This will still not restore the 10/8 format which apparently used
to work in iproute, so people would have to settle for 10.0/8)

(See http://bugs.debian.org/497011)

The one issue was the old multiqueue API, so that is handled
by tc_util.h

Most newer documentation refers to these values already.

This patch fixes bug in Metadata ematch attributes parser

strtoul on error return ULONG_MAX, not LONG_MAX

Patch attached as file

After changing the DESTDIR the installated binaries have some issues
due to hard coded paths. For example, using distributions on NetEm
would segfault.

I've changed iplink.c and tc_util.c so they are now aware of DESTDIR.
Along with that change I needed to change the main Makefile so it
defines the DESTDIR macro when calling gcc.

I also changed the paths so that during the installation sbin, etc,
share and lib directories are created directly inside of the DESTDIR,
instead of creating a usr directory inside that. That's the behaviour
of most packages out there, so I think most users will be expecting
that to happen.

The command "ip addrlabel add/del" displays incorrect error message when provided with insufficient inputs. This patch fixes it in par with "ip addr add/del".

Currently:
# ./ip addrlabel add

# ./ip addr add
Not enough information: "dev" argument is required.

After patch:
# ./ip addrlabel add
Not enough information: "prefix" argument is required.

Copy santized version of headers from 2.6.26 final version.

Don't just silently drop.

The current kernel generates 71 possible header fields, but
MAX_FIELDS in lnstat is only 64. This leads to referencing outside
of the array. To fix, increase size of array and chop off parsing
at MAX_FIELDS - 1.

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.

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.

The current iproute version uses "protocol all" by default
if its not specified. This is actually only useful for creating
new filters, on deletion an unset protocol is treated as wildcard.

The kernel timers are exposed in user hz not kernel hz

All timer values from kernel are supposed to be in constant
units or user hz value.

The function get_hz() returns the psched hz value which is wrong
for anything other than tc usage. Should be user hz instead, but
kernel is broken (patch sent) and this code doesn't get hit on
current systems (netlink is used first).
