Mike Frysinger f2e27cfb01 support static-only systems
The iptables code supports a "no shared libs" mode where it can be used
without requiring dlfcn related functionality.  This adds similar support
to iproute2 so that it can easily be used on systems like nommu Linux (but
obviously with a few limitations -- no dynamic plugins).

Rather than modify every location that uses dlfcn.h, I hooked the dlfcn.h
header with stub functions when shared library support is disabled.  Then
symbol lookup is done via a local static lookup table (which is generated
automatically at build time) so that internal symbols can be found.

Patrick McHardy 7f03191fda iproute uses too small of a receive buffer
It uses 1MB as receive buf limit by default (without
increasing /proc/sys/net/core/rmem_max it will be limited by less
however) and allows to specify the size manually using "-rcvbuf X"
(-r is already used, so you need to specify at least -rc).

Additionally rtnl_listen() continues on ENOBUFS after printing the
error message.

Srivats P c3651bf476 ip6tunnel: Fix no default display of ip4ip6 tunnels
"ip -6 tunnel show" displays only ip6ip6 tunnels not ip4ip6 tunnels
 - it should display all irrespective of proto.

This is because the default tunnel proto is initialized to IPPROTO_IPV6 in ip6_tnl_parm_init() which is fine for a 'add' command but not for 'show'. This patch overrides proto with 0 signifying 'mode any' as the default in case of a 'show'.

Andreas Henriksson 6cdbf37063 iproute2: drop equalize support.
Hello Stephen and netdev people!

Currently you can configure "equalize" and it looks all fine and dandy.
The kernel has the interface defined, but apparently there's never actually
been any implementation for it (only a never merged patch in the 2.4 era).

I'm suggesting to drop the code to give any potential users of this feature
the benefit of receiving a proper error message. I see it unlikely that
this will be implemented in the near future, but if it ever happens
reviving the iproute2 side should be as easy as git revert this patch.

For more details see http://bugs.debian.org/149897

Andreas Henriksson

Benedikt Gollatz 037d950bce When the preferred lifetime of a prefix assigned by IPv6 autoconfiguration
(router solicitation) becomes negative

How reproducible:

Always.

Steps to Reproduce:
1. Configure an IPv6 router to advertise a prefix with a short preferred
lifetime, e.g. 0.
2. Wait for the IPv6 autoconfiguration process to complete for an interface
<if> connected to a link where that router advertises.
3. Run ip -6 show dev <if>.

Actual results:

The preferred lifetime will have become negative, but it is printed as an
unsigned integer. The preferred lifetime to be displayed will therefore be
close to UINT_MAX.

Olivier Fourdan 7f71c0cae2 ip maddr show” on an infiniband address causes a stack corruption
“ip maddr show” on an infiniband address causes a stack corruption
because the length of the address for Infiniband (20 bytes, as

fit on the 16 bytes of the field in which it gets stored.

The proposed patch increases the size of the hardware address from 4
__u32 to 8 and also adds a check to avoid overriding the available
size while parsing the hardware address.

This bug affects current upstream code AFAICT.

Hope this helps,

Andreas Henriksson 5e3bb534ae iproute: DESTDIR vs LIBDIR.
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.

Rafael Almeida b514b3587e Fixed installation when changing DESTDIR
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.

Herbert Xu de95ae7ca7 xfrm: Allow replay setting
Hi Stephen:

[IP] xfrm: Allow replay setting

For certain applications there is a requirement to start the
sequence number from a point other than the default.  As it
is the kernel provides an interface to do that but it isn't
available through the ip(8) command.  Since we're encouraging
people to migrate over to ip(8) for manual keying, it is useful
to have this ability there.

This patch adds support for setting replay sequence numbers
through ip(8).

YOSHIFUJI Hideaki / 吉藤英明 7c73e1bd21 rto_min value display overflow
Reported by: Satoru SATOH <satoru.satoh@gmail.com>
"ip route show" does not print correct value when larger rto_min is
set (e.g. 3sec).

This problem is because of overflow in print_route() and
the patch below is a workaround fix for that.

[root test]# ./iproute2.git.org/ip/ip route show dev eth1
192.168.140.0/24  proto kernel  scope link  src 192.168.140.130
169.254.0.0/16  scope link
[root test]# ./iproute2.git.org/ip/ip route change 192.168.140.0/24
dev eth1 rto_min 3s
[root test]# ./iproute2.git.org/ip/ip route show dev eth1
192.168.140.0/24  scope link  rto_min lock 2ms     <-- wrong
169.254.0.0/16  scope link
[root test]# ./iproute2.git/ip/ip route show dev eth1  # patched version
192.168.140.0/24  scope link  rto_min lock 3000ms  <-- correct
169.254.0.0/16  scope link

This is a simpler fix.

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.

Pavel Emelianov 4ed390ce43 Make ip utility veth driver aware
The new command is called "veth" with the following syntax:
* ip veth add <dev1> <dev2>
  creates interconnected pair of veth devices.
* ip veth del <dev>
  destroys the pair of veth devices, where <dev> is either
  <dev1> or <dev2> used to create the pair.

One question that is to be solved is whether or not to create
a hard-coded netlink family for veth driver. Without it the
family resolution code has to be moved to general place in ip
utility (by now it is copy-paste-ed from one file to another
till final decision).
