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
described in kernel doc Documentation/infiniband/ipoib.txt) does not
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,
Cheers,
Olivier.

Herbert Xu 72c771b20e Update version of IP gre
This patch adds support for configuring GRE tunnels using the
new rtnl_link interface.  This only works on kernels that have
the new GRE configuration interface.

This is accessed through the "ip link" command.  The previous
tunnel configuration interface "ip tunnel" remains as it is
and should be retained for compatibility with old kernels.

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.

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

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.

Benjamin Thery 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.

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).
