additional information for commit 2a93c580

Now that the status page api has been rewritten in C CPU load and memory
usage is much lower. Also, nodes with both ibss and 11s mesh and dual
band wifi may require up to 9 connections for a single client, thus the
previous limit of 12 seemed a little low.

This will make it easier to replace the API with C programs.

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

When rebooting the node in config mode, currently the fastd key is
forcefully displayed in a fixed format. This is confusing in communities
where fastd accepts all keys and no key submission is needed.
Furthermore, some communities might want to personalize the display of
the key (see #387).

This patch moves the displaying <div> from the package's lua file to the
translation files of the sample site configuration and mentiones the
change in the release notes.

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,
            },
    },

Using service_start requires exporting of environment variables.

Fixes #397

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.

This was broken due to the switch to Chaos Calmer.

This fixes MAC address conflicts on devices which use the eth0 as primary
address.

This should fix the signal strength indicators on the TP-Link CPE210/510.

These targets don't have a WLAN adapter by default, so it doesn't make
sense to default to the phy0 address.

error() is a glibc specific function and should not be used in
code meant to be portable.

This limits the number of concurrent users to 2 or 3 (approx. 4 connections per
user), greatly reducing DoS potential.

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.

Export Mode -> Expert Mode

15 is the default in batman-adv-legacy, the new default 30 in newer batman-adv
versions is too high in larger networks.
