Hello!

While building the iproute package in Debian I get warnings from
package helpers like this:

dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/iproute/sbin/tc debian/iproute/usr/bin/lnstat debian/iproute/bin/ip debian/iproute/bin/ss debian/iproute/sbin/bridge debian/iproute/sbin/rtmon were not linked against libresolv.so.2 (they use none of the library's symbols)

The -lresolv in ./Makefile seems to come from pre-historic times (before
iproute2 git history, possibly from libc5/pre-glibc days).
I couldn't find out if/why there was any reason for linking to libresolv.
Does anyone know if there are any valid reasons for keeping it still?

If not, I'd be happy to see it go.... while at it I also removed includes
of <resolv.h> which I also couldn't find any reason for, but this is
just an added bonus of the patch (and there are probably more unneeded
includes that could be dropped in the same sources).

Rather than hard coding `pkg-config`, use ${PKG_CONFIG} so people can
override it to their specific version (like when cross-compiling).

This is the same way the upstream pkg-config code works.

That is -- write the code, that sends diag request in new format. It's
mostly copied from tcp-diag code. Plus, sock-diag differentiates sockets
by families, thus we have to send two requests sequentially.

If we fail to submit new sock-diag request, try to fall-back and submit
the legacy tcp-diag one.
Signed-off-by: Pavel Emelyanov <xemul@parallels.com>

The existing function inet_show_netlink sends tcp-diag request and
then receives back the response and prints it on the screen.

The sock-diag and legacy tcp-diag have different request types, but
report sockets in the same format. In order to support both it's
convenient to split the code into sending and receiving parts.

The sock-diag is capable to diag udp sockets as well. Prepare the
ss code for this by first renaming soon-to-be-generic tcp-s names
into inet-s.

Also sort link types for clarity

Added support to ipoib rtnl ops through which one can create, configure,

 $ ip link add link ib0.1 name ib0.1 type ipoib mode connected
 $ ip --details link show dev ib0.1

Hi,

When compiling iproute2-3.6.0 on a host that doesn't have iptables available, I get the following error:

gcc -Wall -Wstrict-prototypes -O2 -I../include -DRESOLVE_HOSTNAMES
-DLIBDIR=\"/usr/lib\" -DCONFDIR=\"/etc/iproute2\" -D_GNU_SOURCE
-DCONFIG_GACT -DCONFIG_GACT_PROB -DYY_NO_INPUT   -c -o em_ipset.o
em_ipset.c
em_ipset.c:26:21: fatal error: xtables.h: No such file or directory

Fixed by the following patch, which guards the building of em_ipset.o on
the presence of suitable headers.

Thanks,

Matt.

This functionality is required by checkpoint-restore project. Since the

Some time ago the save+restore commands were added to ip route (git
id f4ff11e3, Add ip route save/restore). These two save the raw rtnl
stream into a file and restore one (reading it from stdin).

The problem is that there's no way to get the contents of the dump
file in a human readable form. The proposal is to add a command that
reads the rtnl stream from stdin and prints the data in a way the
usual "ip route list" does?

changes since v1:

* Take the magic at the beginning of the dump file into account
* Check for stdin (the dump is taken from) is not a tty

In order to somehow verify that a blob contains route dump a
