Hello David,

our debugging campaign continues..

Here I have another small set of fixes intended for net/linux-3.15 and *stable*
(please enqueue them).

I know we already sent some fixes and we are running late in the rc cycle, but,
as you can see from the stats below, the changes are very very small.

Patch 1 prevents a NULL dereference in batadv_orig_hardif_seq_print_text() along
the failure path.

Patch 2 fixes a reference counting imbalance that gets triggered everytime the
batman packet fragmentation mechanism is used; this imbalance prevents the
netdev object held by batman-adv from being released on shutdown.

Patch 3 fixes the reference counting for the orig_node objects in order to avoid
any access after they have been free'd.

Patch 4 fixes the TT local check in DAT (Distributed ARP Table) that is used to
avoid sending (self-forged) ARP replies on behalf of other host in the LAN.

Please pull or let me know of any problem!

Thanks a lot,
Antonio
