  • cbebd363b   batman-adv: Use own timer for multicast TT and TVLV updates ... Browse Code »

    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.

  • 4e3e823b5   batman-adv: Add debugfs table for mcast flags ... Browse Code »

    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.

  • 1e2c2a4fe   batman-adv: Add required includes to all files ... Browse Code »

    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.

  • 1d8ab8d3c   batman-adv: Modified forwarding behaviour for multicast packets ... Browse Code »

    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.

    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.

    With this patch a node which has no bridge interface on top of its soft
    interface announces its local multicast listeners via the translation
