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.

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.

my_skb_push provided an easy way to allocate enough headroom in situation were we don't have enough space left and move the data pointer to the new position, but we didn't checked wether we are allowed to write to the new pushed header. This is for example a problem when the skb was cloned and thus doesn't have a private data part. my_skb_head_push now replaces my_skb_push by using skb_cow_head to provide only a large enough, writable header without testing for the rest of the (maybe shared) data. It will also move the data pointer using skb_push when skb_cow_head doesn't fail. This should give us enough flexibility in situation were skbs will be queued by underlying layers and still doesn't unnecessarily copy the data in situations when the skb was consumed right away during dev_queue_xmit.

We include different header files indirectly to the same source file. This creates weird compiler errors from time to time. Include guards should prefend that functions/variables/... gets redefined by itself. Signed-off-by: NSven Eckelmann <sven.eckelmann@gmx.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Functions and variables which are used only inside one object file can be declared as static. This helped to find unused functions/variables * mainIfAddr_default * main_if_was_up and functions with declarations but missing definitions * hash_debug * orig_find * send_own_packet_work Signed-off-by: NSven Eckelmann <sven.eckelmann@gmx.de> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This patch removes the (ugly and racy) packet receiving thread and the kernel socket usage. Instead, packets are received directly by registering the ethernet type and handling skbs instead of self-allocated buffers. Some consequences and comments: * we don't copy the payload data when forwarding/sending/receiving data anymore. This should boost performance. * packets from/to different interfaces can be (theoretically) processed simultaneously. Only the big originator hash lock might be in the way. * no more polling or sleeping/wakeup/scheduling issues when receiving packets * this might introduce new race conditions. * aggregation and vis code still use packet buffers and are not (yet) converted. * all spinlocks were converted to irqsave/restore versions to solve some lifelock issues when preempted. This might be overkill, some of these locks might be reverted later. * skb copies are only done if neccesary to avoid overhead performance differences: * we made some "benchmarks" with intel laptops. * bandwidth on Gigabit Ethernet increased from ~500 MBit/s to ~920 MBit/s * ping latency decresed from ~2ms to ~0.2 ms I did some tests on my 9 node qemu environment and could confirm that usual sending/receiving, forwarding, vis, batctl ping etc works.
