Gcc now warns about possible errors from passing a string
buffer as format arguement to printf().

Still had references to l_name.

1)optind according iptables sources have to be set to 0. If it is set to 1, in
batch it will mess up things. Also in iptables sources i notice that ->tflags
and ->used need to be reset.

2)Since target->t = fw_calloc(1, size); allocated memory in function build_st,
it have to be freed at the end, or in batch we will have memory leak. TODO:
Probably it must be freed in all "return -1" cases in parse_ipt after
build_st. About this i am not sure, up to Stephen.

3)new_name was malloc'ed, but not freed

(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.

“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.

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.

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.

Patch adds generic size table that is similiar to rate table, with
difference that size table stores link layer packet size.

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.
