This mark prevents a multicast packet being flooded through the whole
mesh. The advantage of marking certain multicast packets via e.g.
ebtables instead of dropping is then the following:

This allows an administrator to let specific multicast packets pass as
long as they are forwarded to a limited number of nodes only and are
therefore creating no burdon to unrelated nodes.

Implement a configurable MLD Querier wake-up calls "feature" which
works around a widely spread Android bug in connection with IGMP/MLD
snooping.

Currently there are mobile devices (e.g. Android) which are not able
to receive and respond to MLD Queries reliably because the Wifi driver
filters a lot of ICMPv6 when the device is asleep - including
MLD. This in turn breaks IPv6 communication when MLD Snooping is
enabled. However there is one ICMPv6 type which is allowed to pass and
which can be used to wake up the mobile device: ICMPv6 Echo Requests.

If this bridge is the selected MLD Querier then setting
"multicast_wakeupcall" to a number n greater than 0 will send n
ICMPv6 Echo Requests to each host behind this port to wake
them up with each MLD Query. Upon receiving a matching ICMPv6 Echo
Reply an MLD Query with a unicast ethernet destination will be sent
to the specific host(s).

Instead of unconditionally loading this module on boot the gluon_bat0
netifd protocol script will later take care of loading either the
batman-adv or batman-adv-legacy module, depending on the configured routing
algorithm in UCI.

This reverts commit 8dd13cbb.

Fixes #1756

This reverts commit 3d3617ed.

This updates the batman-adv OpenWrt package to the current version
provided in the master branch of the openwrt-routing packages
repository:

* e26096a batman-adv: Fix duplicated OGMs on NETDEV_UP
* 1ff00ee batman-adv: upgrade package to latest release 2019.2

Small difference to the original:

* Compat code for batadv_genl_dump_check_consistent()
* Compat code for cfg80211_sinfo_release_content()
* 0001-batman-adv-add-compat-hacks.patch kept
* batctl dependency kept removed
* config related files unchanged

The new config format was not backported yet to keep this patch small
and less invasive.

This always pulls in the batman-adv compat 15 kernel module. However,
batctl works just as well with batman-adv-legacy (compat 14).

2dfb22876414 batman-adv: add patches from 2018.1-maint 2018-06-03

A reference to the best gateway is taken when the list of gateways in the
mesh is sent via netlink. This is necessary to check whether the currently
dumped entry is the currently selected gateway or not. This information is
then transferred as flag BATADV_ATTR_FLAG_BEST.

After the comparison of the current entry is done,
batadv_*_gw_dump_entry() has to decrease the reference counter again.
Otherwise the reference will be held and thus prevents a proper shutdown of
the batman-adv interfaces (and some of the interfaces enslaved in it).

Fixes checksum failures on TT version updates.

Fixes #1321

The first one adds a fix that might potentially result in multicast packet
loss once we would enable multicast_mode again.

The second one avoids some small but unnecessary overhead. More
importantly though, it is supposed to ease further multicast improvements
later (e.g. no need for a multicast sending node to determine overlap
between WANT_ALL_IPV4/6 flags and TT entries while on fast-path).

Improves performance slightly.

Fixes "hw csum failure" log spam in batman-adv.

Updates batman-adv and alfred to 2017.1. This also allows us to drop our
last batman-adv patch.

Also remove our own no_rebroadcast patch, as batman-adv v2016.5 now has a
more sophisticated rebroadcast suppression that should work automatically
in the most relevant cases.

Fixes a build issue when switching targets.

This lifts batman-adv and alfred to version 2016.4.

Introduce new fixes:

 * Avoid nullptr dereference in bla after vlan_insert_tag
 * Avoid nullptr dereference in dat after vlan_insert_tag
 * Avoid tt_req_node list put for unhashed entry
 * Fix orig_node_vlan leak on orig_node_release
 * Fix non-atomic bla_claim::backbone_gw access
 * Fix reference leak in batadv_find_router
 * Free last_bonding_candidate on release of orig_node

Also replace the gluon version of the speedyjoin patch with the one already
included in openwrt-routing.

Signed-off-by: Sven Eckelmann <sven.eckelmann@open-mesh.com>

Speedy join only works when the received packet is either broadcast or an
4addr unicast packet. Thus packets converted from broadcast to unicast via
the gateway handling code have to be converted to 4addr packets to allow
the receiving gateway server to add the sender address as temporary entry
to the translation table.

Not doing it will make the batman-adv gateway server drop the DHCP response
in many situations because it doesn't yet have the TT entry for the
destination of the DHCP response.

batman-adv & alfred 2016.2.

Should be redundant after 0bd0df6f

This also updates batman-adv & alfred to 2015.1

This should workaround batman-adv's inability to deal with different MTUs
which need fragmentation.
