pull request: batman-adv 2013-10-23

[Antonio Quartulli <antonio@meshcoding.com>]

Hello David,

this is another set of changes intended for net-next/linux-3.13.
(probably our last pull request for this cycle)

Patches 1 and 2 reshape two of our main data structures in a way that they can
easily be extended in the future to accommodate new routing protocols.

Patches from 3 to 9 improve our routing protocol API and its users so that all
the protocol-related code is not mixed up with the other components anymore.

Patch 10 limits the local Translation Table maximum size to a value such that it
can be fully transfered over the air if needed. This value depends on
fragmentation being enabled or not and on the mtu values.

Patch 11 makes batman-adv send a uevent in case of soft-interface destruction
while a "bat-Gateway" was configured (this informs userspace about the GW not
being available anymore).

Patches 13 and 14 enable the TT component to detect non-mesh client flag
changes at runtime (till now those flags where set upon client detection and
were not changed anymore).

Patch 16 is a generalisation of our user-to-kernel space communication (and
viceversa) used to exchange ICMP packets to send/received to/from the mesh
network. Now it can easily accommodate new ICMP packet types without breaking
the existing userspace API anymore.


Remaining patches are minor changes and cleanups.


Please pull or let me know of any problem.

Thanks a lot,
	Antonio

  batman-adv: generalize batman-adv icmp packet handling (2013-10-23 17:03:47 +0200)

----------------------------------------------------------------
Included changes:
- data structure reshaping to accommodate multiple routing protocol
  implementations
- routing protocol API enhancement
- send to userspace the event "batman-adv Gateway loss" in case of soft-iface
  destruction and a "batman-adv Gateway" was configured
- improve the TT component to support and advertise runtime flag changes
- minor code refactoring
- make the ICMP kernel-to-userspace communication more generic
