2b68cb77cd libgenl: introduce genl_init_handle
All users of genl have the same code to open a genl socket and resolve
the family for their specific protocol.  Introduce a helper to initialize
the handle, and use it in all the genl code.

c079e121a7 libnetlink: add size argument to rtnl_talk
There have been several instances where response from kernel
has overrun the stack buffer from the caller. Avoid future problems
by passing a size argument.

Also drop the unused peer and group arguments to rtnl_talk.

dd10baa50d iproute2: add l2spec_type param to l2tp add session
When unmanaged L2TP sessions are created using "ip l2tp add session",
there is no option to allow the session's Layer2SpecificHeader type to
be selected - the kernel's default setting is always used. For
interopability with some vendor equipment, it might be necessary to
use a different setting. So add a new l2spec_type parameter to the "ip
l2tp add session" parameter list, allowing operators to set a specific
Layer2SpecificHeader type. The kernel already exposes the setting as a
netlink attribute so it is straightforward to add support for it in
iproute2.

This change allows unmanaged L2TP sessions to be configured between
Linux and some Cisco equipment by specifying "l2spec_type none" in "ip
l2tp add session" command parameters.

14645ec231 iproute2: improved error messages
This patch improves many error messages as follows:
- For incorrect parameters, show the value of the offending parameter, rather than just say that it is incorrect
- Rephrased messages for clarity
- Rephrased to more `mainstream' english

new macro.

6618e334ba iproute2: allow IPv6 addresses for l2tp local and remote parameters
Adds support for parsing IPv6 addresses to the parameters local and
remote in the l2tp commands. Requires netlink attributes L2TP_ATTR_IP6_SADDR
and L2TP_ATTR_IP6_DADDR, added in a required kernel patch already submitted
to netdev.

Also enables printing of IPv6 addresses returned by the L2TP_CMD_TUNNEL_GET
request.

6e30461e73 iproute2: man page and /bin/ip disagree on del vs delete
Reported by Robert Henney:
> the 'ip' man page does not mention the command "del" at all but does
> claim, "As a rule, it is possible to add, delete and show (or list ) objects".
> however, 'ip' does not always recognize "delete" as a commend.
>
> robh@debian:~$ ip tunnel delete
> Command "delete" is unknown, try "ip tunnel help".

Lets use "delete" in all calls to matches() for consistency. This will
make both "del" and "delete" work everywhere.

ae5555d334 ipl2tp: allow setting session interface name
Hi,

I've attached a trivial patch for iproute2 to allow naming interfaces
created with "ip l2tp add session".

I believe patches should go through the netdev mailing list but this
patch is so small I figured that would just add noise. Hope that's OK.

Originally I thought I would need a bigger patch and was going to take a
stab at implementing something like

ip l2tp add tunnel L2TP_TUNNEL_ARGS
ip link add name NAME  [ LINK_OPTS ] type l2tp L2TP_SESSION_ARGS

(a better interface IMHO) but all the code was there already, all that I
needed to add was option parsing.

Thanks,

João Valverde
