batman-adv: Prefix soft-interface non-static functions with batadv_ batman-adv can be compiled as part of the kernel instead of an module. In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions. A prefix for the batman-adv symbols that defines their private namespace avoids such a problem. Reported-by: David Miller <davem@davemloft.net> Signed-off-by: Sven Eckelmann <sven@narfation.org>

batman-adv: change interface_rx to get orig node In order to understand where a broadcast packet is coming from and use this information to detect not yet announced clients, this patch modifies the interface_rx() function by passing a new argument: the orig node corresponding to the node that originated the received packet (if known). This new argument if not NULL for broadcast packets only (other packets does not have source field). Signed-off-by: Antonio Quartulli <ordex@autistici.org>

batman-adv: Allow to use rntl_link for device creation/deletion The sysfs configuration interface of batman-adv to add/remove soft-interfaces is not deadlock free and doesn't follow the currently common way to create new virtual interfaces. An additional interface though rtnl_link is introduced which provides easy device creation/deletion with tools like "ip": $ ip link add dev bat0 type batadv $ ip link del dev bat0 Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Antonio Quartulli <ordex@autistici.org>

batman-adv: add per VLAN interface attribute framework Since batman-adv is now fully VLAN-aware, a proper framework able to handle per-vlan-interface attributes is needed. Those attributes will affect the associated VLAN interface only, rather than the real soft_iface (which would result in every vlan interface having the same attribute configuration). To make the code simpler and easier to extend, attributes associated to the standalone soft_iface are now treated like belonging to yet another vlan having a special vid. This vid is different from the others because it is made up by all zeros and the VLAN_HAS_TAG bit is not set.

batman-adv: add sysfs framework for VLAN Each VLAN can now have its own set of attributes which are exported through a new subfolder in the sysfs tree. Each VLAN created on top of a soft_iface will have its own subfolder. The subfolder is named "vlan%VID" and it is created inside the "mesh" sysfs folder belonging to batman-adv. Attributes corresponding to the untagged LAN are stored in the root sysfs folder as before. This patch also creates all the needed macros and data structures to easily handle new VLAN spacific attributes.
