batman-adv: Add lower layer needed_(head|tail)room to own ones

2015-08-27T18:15:34+00:00

The maximum of hard_header_len and maximum of all needed_(head|tail)room of
all slave interfaces of a batman-adv device must be used to define the
batman-adv device needed_(head|tail)room. This is required to avoid too
small buffer problems when these slave devices try to send the encapsulated
packet in a tx path without the possibility to resize the skbuff.

batman-adv: don't access unregistered net_device object

2015-08-27T18:15:33+00:00

In batadv_hardif_disable_interface() there is a call to
batadv_softif_destroy_sysfs() which in turns invokes
unregister_netdevice() on the soft_iface.
After this point we cannot rely on the soft_iface object
anymore because it might get free'd by the netdev periodic
routine at any time.

For this reason the netdev_upper_dev_unlink(.., soft_iface) call
is moved before the invocation of batadv_softif_destroy_sysfs() so
that we can be sure that the soft_iface object is still valid.

batman-adv: remove obsolete deleted attribute for gateway node

2015-08-27T18:15:32+00:00

With rcu, the gateway node deleted attribute is not needed anymore. In
fact, it may delay the free of the gateway node and its referenced
structures. Therefore remove it altogether and simplify purging as well.

batman-adv: move neigh_node list add into batadv_neigh_node_new()

2015-08-27T18:15:31+00:00

All batadv_neigh_node_* functions expect the neigh_node list item to be part
of the orig_node->neigh_list, therefore the constructor of said list item
should be adding the newly created neigh_node to the respective list.

The batadv_neigh_node_new() function already sets the hard_iface pointer.

batman-adv: move hardif refcount inc to batadv_neigh_node_new()

2015-08-27T18:15:30+00:00

The batadv_neigh_node cleanup function 'batadv_neigh_node_free_rcu()'
takes care of reducing the hardif refcounter, hence it's only logical
to assume the creating function of that same object
'batadv_neigh_node_new()' takes care of increasing the same refcounter.
