2016-10-30batman-adv: Use own timer for multicast TT and TVLV updatesLinus Lüssing
Instead of latching onto the OGM period, this patch introduces a worker dedicated to multicast TT and TVLV updates. The reasoning is, that upon roaming especially the translation table should be updated timely to minimize connectivity issues. With BATMAN V, the idea is to greatly increase the OGM interval to reduce overhead. Unfortunately, right now this could lead to a bad user experience if multicast traffic is involved. Therefore this patch introduces a fixed 500ms update interval for multicast TT entries and the multicast TVLV.

2016-06-30batman-adv: Add debugfs table for mcast flagsLinus Lüssing
This patch adds a debugfs table with originators and their according multicast flags to help users figure out why multicast optimizations might be enabled or disabled for them.

2015-08-25batman-adv: Remove batadv_ types forward declarationsSven Eckelmann
main.h is included in every file and is the only way to access types.h. This makes forward declarations for all types defined in types.h unnecessary.

2015-06-07batman-adv: Add required includes to all filesSven Eckelmann
The header files could not be build indepdent from each other. This is happened because headers didn't include the files for things they've used. This was problematic because the success of a build depended on the knowledge about the right order of local includes. Also source files were not including everything they've used explicitly. Instead they required that transitive includes are always stable. This is problematic because some transitive includes are not obvious, depend on config settings and may not be stable in the future. The order for include blocks are: * primary headers (main.h and the *.h file of a *.c file) * global linux headers * required local headers * extra forward declarations for pointers in function/struct declarations The only exceptions are linux/bitops.h and linux/if_ether.h in packet.h. This header file is shared with userspace applications like batctl and must therefore build together with userspace applications. The header linux/bitops.h is not part of the uapi headers and linux/if_ether.h conflicts with the musl implementation of netinet/if_ether.h. The maintainers rejected the use of __KERNEL__ preprocessor checks and thus these two headers are only in main.h. All files using packet.h first have to include main.h to work correctly.

2014-03-22batman-adv: Modified forwarding behaviour for multicast packetsLinus Lüssing
With this patch a multicast packet is not always simply flooded anymore, the behaviour for the following cases is changed to reduce unnecessary overhead: If all nodes within the horizon of a certain node have signalized multicast listener announcement capability then an IPv6 multicast packet with a destination of IPv6 link-local scope (excluding ff02::1) coming from the upstream of this node... * ...is dropped if there is no according multicast listener in the translation table, * ...is forwarded via unicast if there is a single node with interested multicast listeners * ...and otherwise still gets flooded.

2014-03-22batman-adv: Announce new capability via multicast TVLVLinus Lüssing
If the soft interface of a node is not part of a bridge then a node announces a new multicast TVLV: The existence of this TVLV signalizes that this node is announcing all of its multicast listeners via the translation table infrastructure.
