* Staging: batman-adv: Fix merge of linus treeSven Eckelmann2010-08-231-0/+4
| | | | | | | | | | | Greg Kroah-Hartman merged Linus 2.6.36 tree in e9563355ac1175dd3440dc2ea5c28b27ed51a283 with his staging tree. Different parts of the merge conflicts were resolved incorrectly and may result in an abnormal behavior.

| * Staging: batman-adv: Move printk to simplified macrosSven Eckelmann2010-07-081-46/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each general printk which is not informative by itself for a specific batX device were moved to pr_(info|warning|err) as it provides an easy interface which for example resolves the problem to add the prefix "batman-adv: " before each line. All information which is specific to a batX device will be printed using a bat_(info|err|warning) macro to prefix it also with "batman-adv: batX:" in each line.

| * Staging: batman-adv: add routing debug log accessible via debugfsMarek Lindner2010-07-081-0/+54
| | | | | | | | | | | | | | | | | | | | | | All routing debug messages are saved in a ring buffer that can be read via the debugfs file "log". Note that CONFIG_BATMAN_ADV_DEBUG must be activated to have the debug logs compiled in.

| * Staging: batman-adv: Add bonding functionalitySimon Wunderlich2010-06-221-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces bonding functionality to batman-advanced, targeted for the 0.3 release. As we are able to route the payload traffic as we want, we may use multiple interfaces on multihomed hosts to transfer data to achieve higher bandwidth. This can be considered as "light Multi Path Routing" for single hop connections. To detect which interfaces of a peer node belong to the same host, a new flag PRIMARIES_FIRST_HOP is introduced. This flag is set on the first hop of OGMs of the primary (first) interface, which is broadcasted on all interfaces. When receiving such an OGM, we can learn which interfaces belong to the same host (by assigning them to the primary originator). Bonding works by sending packets in a round-robin fashion to the available interfaces of a neighbor host, if multiple interfaces are available. The neighbor interfaces should be almost equally good to reach. To avoid interferences (i.e. sending on the same channel), only neighbor interfaces with different mac addresses and different outgoing interfaces are considered as candidates. Bonding is deactivated by default, and can be activated by echo 1 > /sys/class/net/bat0/mesh/bonding for each individual node.

| * Staging: batman-adv: permit setting ogm interval to JITTER*2Linus Lüssing2010-06-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | When trying to set the originator interval to 40ms, we are asked to set it to a minimum value of 40ms. This patch permits setting an originator interval of JITTER*2 (40ms by default) now.

| | | | | | | | | | | | | | | | | | | | Files which represent more than a single attribute aren't allowed in sysfs. As we have some files which aren't essential and are lists or tables aggregated from data from different places inside batman-adv, we must place them in a filesystem without such a restriction.

* Staging: batman-adv: move /proc interface handling to /sysMarek Lindner2010-05-111-0/+147
| | | | | | | | | | | | | | | | | | | | | | | Instead of having a single /proc file "interfaces" in which you have to echo the wanted interface batman-adv will create a subfolder in each suitable /sys/class/net folder. This subfolder contains files for the interface specific settings. For example, mesh_iface to add/remove an interface from a virtual mesh network (at the moment only bat0 is supported). Example: echo bat0 > /sys/class/net/eth0/batman-adv/mesh_iface to deactivate: echo none > /sys/class/net/eth0/batman-adv/mesh_iface Interfaces which are not compatible with batman-adv won't contain the batman-adv folder, therefore can't be activated. Not supported are: loopback, non-ethernet, non-ARP and virtual mesh network interfaces Signed-off-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* Staging: batman-adv: convert multiple /proc files to use sysfsMarek Lindner2010-05-111-0/+272
This is the first patch in a series of patches which aim to convert all batman-adv /proc files to sysfs. To keep the changes in a digestable size it has been split up into smaller chunks. During the transition period batman-adv will use /proc as well as sysfs. As a first step the following files have been converted: aggregate_ogm, originators, transtable_global, transtable_local Signed-off-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
