We are mostly dealing with the 2.4GHz crap-band here, so increasing the
IGMP/MLD robustness parameter to three to be able to compensate for up
to two consecutive instead of just one lost packet.

There are some devices not acting properly to roaming events, in that
they do not timely reissue IGMP/MLD reports after reconnecting.
To compensate for that this commit reduces the query interval from 125
seconds to 20 and the query response interval from 20 seconds to 5.
This reduces a timeout to 20+5 seconds in the worst-case (12.5s average)
after a roaming event for such broken devices. This should be below the
30s "impatient user threshold" and below any connection timeout.
Until the bridge multicast snooping + querier gets re-enabled this is a
no-op.

An IGMP/MLD domain split will prevent us from being able to track
multicast listeners on other nodes.
Therefore we need to always hand any multicast packets we received from
local clients to batman-adv. With bridge multicast snooping disabled,
the current setting in Gluon, this is already the case.
However, in preparation to enabling multicast snooping, we need to
enforce forwarding towards batman-adv by setting the bridge port
option "multicast_router" to 2.

Ethernet links provide transitive connectivity in all but very unusual
setup, enable mesh_no_rebroadcast to reduce load for devices on links with
many nodes.
Fixes#652
Is makes sense to always look for both ibss_radio* and mesh_radio* sections
to determine if the meshing should be enabled when regenerating these
sections. Doing this, the disabled state will survive updates changing the
section name (either updating from pre-2015.2 while keeping IBSS, or
changing from IBSS to 11s or vice-versa).
If both ibss_radio* and mesh_radio* sections exist, the disabled state will
be kept correctly for each section, the behaviour is changed only when
creating a section that didn't exist before.
Fixes#549
Convert option ifname in br-client to use a list instead. This
simplifies adding and remove interfaces:
uci:add_to_set("network", "client", "ifname", "eth0")
uci:remove_from_set("network", "client", "ifname", "eth0")
An option ifname will be automatically converted to a list when
performing an upgrade.
Packages affected: gluon-mesh-batman-adv-core, gluon-luci-portconfig
Apart from replacing a patch for the former by two patches for latter,
this involved minimal adaptations of the lua scripts in the following
packages:
* gluon-announce
* gluon-announced
* gluon-mesh-batman-adv-core
* gluon-status-page
Split basic radio configuration from gluon-mesh-batman-adv as this will
be required for virtually any wireless mesh protocol.
This package takes care of setting:
- wireless channel,
- htmode and
- regulatory domain
gluon-mesh-batman-adv-core depends on this package.
This is a site.conf-breaking change in regard to the wireless config.
Make sure to read http://gluon.readthedocs.org/en/latest/user/site.html
and update your site.conf accordingly!
Support for 802.11s mesh interfaces has been added. Gluon now supports
three interface types: ap, ibss and mesh. All of them are now optional
and may be configured independently in site.conf.
A sample site.conf may look like this:
wifi24 = {
channel = 1,
htmode = 'HT40+',
ap = {
ssid = 'luebeck.freifunk.net',
},
ibss = {
ssid = '02:d1:11:37:fc:38',
bssid = '02:d1:11:37:fc:38',
mcast_rate = 12000,
},
mesh = {
id = 'ffhl-mesh',
mcast_rate = 12000,
},
},
The nodeinfo/network/addresses announcement included deprecated and
tentative addresses, which it clearly shouldn't as the host doesn't want
to be contacted on those addresses. They are now filtered out.
Always output empty objects or nothing at all where objects are expected, but
no elements exist.
Also remove a few unneeded "requires", a few basic modules are provided by
announce.lua by default.
This adds mesh_on_lan functionality.
A new optional site.conf option, mesh_on_lan, has been added. If set to
'true', all LAN ports will be used for meshing instead of being part of
the client bridge.
This will introduce a new nodeinfo object, network.mesh.bat0.interfaces,
containing any of the the following subordinated objects:
- wireless
- tunnel
- other
Each of these objects contains a (possibly empty) list of MAC addresses
(lowercase, colon-notation) corresponding to a interface of the given
class. Combined with a batman graph it is thus possible to mark
sub-graphs as "wireless" or "vpn".
The previously used object mesh_intefaces is superseded by this new
object structure and mesh_interfaces will be removed in a future Gluon
release.
This adds a new announce.d datum "neighbours" (alfred 160) containing
information about mesh neighbours. It's intended to be an replacement
for batadv-vis.
In addition to the data already provided by batadv-vis it'll also
provide information about direct wifi neighbours.
Unlike batadv-vis, no data about clients is transmitted.
Sample data:
{
"wifi": {
"90:f6:52:82:06:02": {
"neighbours": {
"f8:d1:11:2c:a7:d2": {
"noise": -95,
"inactive": 0,
"signal": 0
},
"96:f6:52:ff:cd:6f": {
"noise": -95,
"inactive": 0,
"signal": -37
}
}
}
},
"batadv": {
"90:f6:52:82:06:02": {
"neighbours": {
"96:f6:52:ff:cd:6f": {
"lastseen": 2.8500000000000001,
"tq": 177
}
}
},
"90:f6:52:82:06:03": {
"neighbours": {
"f8:d1:11:2c:a7:d3": {
"lastseen": 2.3500000000000001,
"tq": 206
}
}
}
},
"node_id": "90f652820602"
}
Moving the scripts to a common directory not only vastly simplifies the
zzz-gluon-upgrade script, but also allows to define an ordering of such
scripts across packages.
This adds
"client" { "total": <int>, "wifi": <int>" }
to statistics.d. "total" will be the number of clients connected.
"wifi" will be the number of clients connected over wifi. I.e. "total"
will always be equal to or greater than "wifi".
The node will not count itself.
