* Staging: batman-adv: Mark debugfs files as nonseekableSven Eckelmann2010-09-201-0/+3
| | | | | | | | | We don't allow to seek in the debugfs socket and log files. Thus we should mark the file descriptor as nonseekable. Signed-off-by: Sven Eckelmann <sven.eckelmann@gmx.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Staging: batman-adv: multiple mesh cloudsMarek Lindner2010-09-051-5/+6
| | | | | | | | | | | | | | This patch removes all remaining global variables and includes the necessary bits into the bat_priv structure. It is the last remaining piece to allow multiple concurrent mesh clouds on the same device. A few global variables have been rendered obsolete during the process and have been removed entirely.

* Staging: batman-adv: attach each hard-interface to a soft-interfaceMarek Lindner2010-09-051-0/+1
| | | | | | | | | | | | | This patch replaces the static bat0 interface with a dynamic/abstracted approach. It is now possible to create multiple batX interfaces by assigning hard interfaces to them. Each batX interface acts as an independent mesh network. A soft interface is removed once no hard interface references it any longer.

* Staging: batman-adv: Directly prepare icmp packets in socket bufferSven Eckelmann2010-09-051-22/+38
| | | | | | | | | | | It is unnecessary to generate an icmp packet in an extra memory region and than copying it to a new allocated skb. This also resolved the problem that we do inform the user that we couldn't send the packet because we couldn't allocate the socket buffer.

* Staging: batman-adv: fix batman icmp originating from secondary interfaceMarek Lindner2010-08-231-4/+8
| | | | | | | | | | | | | | | | If a batman icmp packet had to be routed over a secondary interface at the first hop, the mac address of that secondary interface would be written in the 'orig' field of the icmp packet. A node which is more than one hop away is not aware of the mac address because secondary interfaces are not flooded through the whole mesh and therefore can't send a reply. This patch always sends the mac address of the primary interface in the 'orig' field of the icmp packet.

* Staging: batman-adv: Move printk to simplified macrosSven Eckelmann2010-07-081-3/+2
| | | | | | | | | | | | | | | 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 Lindner2010-07-081-3/+5
| | | | | | | | | | | 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: record route for ICMP messagesDaniel Seither2010-06-221-18/+27
| | | | | | | | | | | | | | | | | The standard layer 3 ping utility can use the record route (RR) option of IP to collect route data for sent ping messages (ping -R). This patch introduces comparable functionality for batman-adv ICMP messages. The patch adds a second batman ICMP packet format (icmp_packet_rr) such that up to 17 MAC addresses can be recorded (sufficient for up to 8 hops per direction). When no RR is wanted, the old icmp_packet without the RR overhead can be sent.

* Staging: batman-adv: Move device for icmp injection to debugfsSven Eckelmann2010-06-221-0/+328
batctl uses /dev/batman-adv to send special batman-adv icmp packets to other nodes in the mesh. To get it working with multiple batX devices we must ensure that every mesh device can have their own socket which is used to inject those packets in exactly one mesh. The current implementation still doesn't allow to use complete separated meshes as we rely on structures which are not part of the private data of a batman device.
