dnsmasq's caching is severly broken and does not handle all answer records
equally. In particular, its cached answers are missing DNSKEY and DS

Remove the cache for now. It may return if dnsmasq is fixed or we switch to

net.ipv6.conf.br-client.forwarding is moved from gluon-client-bridge to
gluon-mesh-batman-adv, as the setting is not useful with non-bridged
protocols.
With the batman-adv multicast support compiled back in again we end up
with multicast addresses in the batman-adv translation table.
Currently we wrongly interpret multicast addresses returned by TT as a
unique host, too, which adds them with a source address filter to
ebtables as well. However, the source address of an ethernet frames is
never supposed to be a multicat one.
This leads to unnecessary entries in ebtables. Fixing this by ignoring
those MAC addreses returned by TT which have the multicast bit set.

This setting allows to enforce manually setting a hostname.
In the initial configuration, the hostname field is now left empty; when

Fixes#1139
Our VXLAN setup was changed to accept VXLAN packets without checksum almost
2 months ago, so we can disable sending the checksums now as well. Slightly
improves performance.
The RFC standard multicast querier interval is 120s. Our querier uses in
interval of 20s for better support of roaming clients, but our robustness
setting of 3 leads to external queriers using the standard interval to be
timeout after only 60s, leading to frequent "querier appeared/disappeared"
messages. Increase robustness so that external queriers with any interval
<180s are supported.
We must ensure that each node becomes IGMP/MLD querier for its local
clients; having only a single querier for the whole mesh is generally
unreliable, leading to frequent "IGMP/MLD querier appeared/disappeared"
messages from batman-adv and unreliable snooping.
In smaller meshes it might be interesting only segment querier domains, but
allow membership reports to pass through the mesh, in order to support
snooping switches outside the mesh without special configuration. A
site.conf switch is provided to control this behaviour.
Fixes#1320
A downside of this behaviour is that the page does not work for IPv4-only
clients, as the redirect will always point at an IPv6 address.
Still, it seems like a good idea to enforce the redirect even from the IPv4
next-node address, as switching nodes while being connected to the status
page would lead to unexpected behaviour.
All Access-Control-Allow-Origin are removed to improve users' privacy. As
the status page API is thus not useful without the status page anymore,
merge them back into a single package.
The status-page-api respondd provider is removed as well.
Fixes#1194
This new status page is significantly smaller than the old one. It always
loads its resources from the same host as the page itself, not requiring

By emitting Lua code to call translate() and pcdata(), we are more
flexible than when doing this internally in the parser. The performance
penalty should be negligible.
This patch moves the prefix4 subnet route from the local-node veth
device to br-client (while keeping the next node ipv4 address on the
local node device).
This is in preparation to allow routing over the br-client interface
later.
This package adds filters to limit the amount of ARP Requests
devices are allowed to send into the mesh. The limits are 6 packets
per minute per client device, by MAC address, and 1 per second per
node in total.
A burst of up to 50 ARP Requests is allowed until the rate-limiting
takes effect (see --limit-burst in the ebtables manpage).
Furthermore, ARP Requests with a target IP already present in the
batman-adv DAT Cache are excluded from the rate-limiting,
both regarding counting and filtering, as batman-adv will respond
locally with no burden for the mesh. Therefore, this limiter
should not affect popular target IPs, like gateways.
However it should mitigate the problem of curious people or
smart devices scanning the whole IP range. Which could create
a significant amount of overhead for all participants so far.

Both gluon.sysconfig and libgluonutil already remove the trailing newline
if it exists. It's nicer to avoid files without a trailing newline, e.g.
for printing the file contents in a terminal.
This is currently only implemented in the gluon-mesh-vpn-fastd
package.
Advertising the public key may be deemed problematic when
your threat-model involves protecting the nodes privacy
from tunnel traffic correlation by onlink observers.
It can be enabled by setting site.mesh_vpn.fastd.pubkey_privacy
to `false`.
If a value is unset or optional, an empty choice is added to the selection.
This empty choice will be marked as invalid if the value is not optional.
This is properly supported for the 'select' widget only for now, and not
for 'radio'.
This package drops all incoming router advertisements except for the
default router with the best metric according to B.A.T.M.A.N. advanced.
Note that advertisements originating from the node itself (for example
via gluon-radvd) are not affected.
Also disabling TX checksums and not only allowing incoming packets without
checksum will provide another small speedup. As doing so would break wired
meshing with VXLAN-enabled nodes that require non-zero checksums, we will
wait a few days before this step.
In addition to significant internal differences in check_site_lib.lua (in
particular unifying error handling to a single place for the upcoming
multi-domain support), this changes the way fields are addressed in site
check scripts: rather than providing a string like 'next_node.ip6', the
path is passed as an array {'next_node', 'ip6'}.
Other changes in site check scripts:
* need_array and need_table now pass the full path to the sub fields to the
subcheck instead of the key and value
* Any check referring to a field inside a table implies that all higher
levels must be tables if they exist: a check for {'next_node', 'ip6'} adds
an implicit (optional) check for {'next_node'}, which allows to remove many
explicit checks for such tables
This should not convert JSON to a Lua table and back, as this loses the
distinction between arrays and objects, but as our site.conf is defined in
Lua anyways (for now), this can be fixed in a later revision.
[Matthias Schiffer: rename to gluon-show-site, rebase]
By basing the Lua gluon.site module on gluonutil_load_site_config(), the

This enables the ebtables internal locking mechanism which

The new gluon.site lua library will eventually replace gluon.site_config
(which is hereby deprecated, but will continue to be supported for a
while).
The new gluon.site library will wrap all values to allow traversing
non-existing tables without errors.
site = require 'gluon.site'
c = site.a.b.c -- doesn't fail even if a or a.b don't exist
The wrapped values must be unwrapped using call syntax:
site_name = site.site_name()
Using the call syntax on a non-existing value will return nil. An
alternative default value may be passed instead:
mac = site.next_node.mac('16:41:95:40:f7:dc')

To reduce the number of packages that need to be listed in
GLUON_SITE_PACKAGES, this adds a new variable GLUON_FEATURES. Sets of
packages are enabled automatically based on the combination of listed
feature flags.
Site-specified package feeds can provide their own feature flag
definitions.
As PROVIDES can be used to replace real packages now, we don't need the
virtual packages as workaround anymore. This also means that the providing
packages don't need to be added to site.mk explicitly anymore when the
default provider is used.
We now create bat0 and primary0 independently of the lower mesh interfaces,
making the whole setup a lot more robust. In particular:
- we can't accidentially destroy primary0 because of concurrent setup and
teardown runs of different interfaces
- bat0 will always exist, even when no mesh interfaces are up (e.g. no link
on wired mesh)
- interfaces going down and up again will never tear down the whole of
batman-adv
- we can enable and disable bat0 independently of the lower interface
states
We always want to prefer the unique node address for outgoing traffic. Note
that this doesn't have an effect with batman-adv, as usually br-client will
be the outgoing interface, so the unique address would be chosen anyways.
macvlan interfaces never directly exchange traffic with the underlying
interface, but only with other hosts behind the interface. In consequence,
router advertisements from the uradvd running on br-client could never
reach local-node, preventing it from getting an IPv6 address without RAs
from an external radvd. Fix this be replacing the macvlan interface with
a veth pair (with the peer interface in br-client).
As a side effect, this saves about 5KB of flash, as the veth module is
simpler than macvlan.
When preparing the migration from macvlan to veth for local-node, MAC
address conflicts occurred as some ports of br-client had the same address
as local-node. Reverting the roles of both interfaces fixes this.
By default, br-client is left as an interface without addresses and
firewall rules that drop everything, so the bridge is used to connect its
ports only. gluon-mesh-batman-adv-core changes this to the usual set
of addresses and firewall rules.
The batadv debugfs requires large memory blocks to write the text debug
tables. This is inefficient for large tables like the global translation
table or the originators table.
The memory requirement can be reduced by using netlink. It copies smaller
packets in a binary format to the userspace program. The respondd module of
gluon-mesh-batman-adv-core can therefore parse larger originator tables
without causing an OOM on systems which are tight on memory.

MAC and IP addresses are switched. This makes the gluon-client-bridge
package more useful for different routing protocols that don't need a
unique address on the client bridge.
As a side effect, gluon-radvd is now using the next-node address, which had
been considered before, but was dismissed to avoid having gluon-radvd
depend on gluon-next-node and gluon-mesh-batman-adv. This will be useful
for announcing default routes via gluon-radvd.
One downside is that this introduces a minor dependency on batman-adv in
gluon-respondd: the hotplug script that checked for the client interface
before will now check for local-node. This doesn't really matter: for mesh
protocols without a local-node interface, the check will do nothing (which
makes sense, as there is no interface to bind to for mesh-wide respondd).
Because we unconditionally appended `-i br-client` to the command line of
respondd, it wasn't restarted when br-client changed state. Now, we use a
jsonfilter expression on the network.interface dump data, similar to how the
other interface names are generated, and only add the interface to the argument
list if it is up.
If cookies are disabled, the Statuspage only displays an empty ("Not connected")
This checks if the localStorage API is available and working and only uses it in this case
Also allows better backwards compatibility.
Users may have defined additional mesh interfaces. Properly migrate these
to avoid subtly breaking the network config (and make them ready for new
mesh protocols).
Switch to:
1. WAN
2. LAN
3. Mesh VPN
As WAN and LAN are setup in gluon-mesh-batman-adv-core (and will be moved
to gluon-core), while the mesh VPN has its own package, giving WAN and LAN
the first indices is preferable.
Just like we enabled multicast snooping on the batman-adv client bridge
again, let's do the same for the WAN side.
With one exception: The IGMP/MLD querier is kept disabled to avoid
becoming too "bossy"/"noisy" on a foreign network. The main router on
the WAN side should perform querying and by that enable
IGMP/MLD/snooping if it considers this appropriate there.

A few issues with the bridge snooping were identified and fixed
upstream in OpenWRT:
* "firewall: Allow IGMP and MLD input on WAN" (r45613)
* "kernel: bridge: backport two snooping related patches" (r45783)
* netifd: "bridge: Fix multicast_to_unicast feature by hairpin+isolate"
(OW: "netifd: update to the latest version, adds multicast-to-unicast fixes" (r46719))
* "kernel: bridge, multicast-to-unicast: assign src after pskb_may_pull()" (r46721)
* "kernel: bridge, multicast-to-unicast: fix echoes on STA" (46765)
These have very likely caused issues with the bridge snooping before,
which led to disabling it in the past. Let's reenable the multicast
snooping now that they were fixed for reduced multicast overhead on the
wifi.
Advantages are the following:
This mildly reduces overhead on the mesh layer. And significantly reduces
overhead on the AP interface and therefore significantly increases
available airtime (the currently most significant scalability bottleneck).
Secondly removes an easy, often accidental node-local Denial-of-Service
vector based on multicast flooding / streaming.
Thirdly, makes node-local multicast streaming feasible.
Finally should noticably increase battery life of mobile devices.

The mesh side has become fairly huge in many communities. Up to
a few thousand entries can currently be found in the forwarding
database (fdb) of a bridge for its bridge port bat0.
The bridge fdb is kind of redundant to the batman-adv global translation
table here. Therefore this patch tries to reduce memory footprint by
following an approach similar to the IGMP/MLD split patchset approach:
Make the bridge oblivious not only regarding multicast listeners towards
the mesh but with this patch unicast hosts on the mesh, too.
If the destination of an ethernet frame is known by the bridge to be a
local one, then the frame is forwarded to the according port. If it is
unknown, then the frame is forwarded to the wifi AP interface and bat0.
mac80211 and batman-adv then know whether to drop or forward a frame
further through their own book-keeping.
Note that unicast-flood is not disabled for the wifi AP bridge port, nor
is learning disabled on the wifi AP. This is mainly to keep the
configuration in UCI and according setup scripts simple ;). However, not
disalbling unicast-flood on the wifi AP interface might also give a
minor latency improvement for newly joining wifi clients.

This patch adds a new gluon-ebtables package to filter IGMP/MLD messages
via ebtables.
For one thing this reduces multicast overhead: About one third of all
ICMPv6 multicast traffic in Lübeck or Hamburg is MLD.
Furthermore it removes a potential Distributed Denial-of-Service vector
(see Gluon ticket #553).
Finally, it is a prerequisite for enabling bridge multicast snooping in
a decentral and robust fashion.
Note that IGMP/MLD are filtered for multicast traffic coming from
the mesh, too (new MULTICAST_IN), as unfortunately there seem to
be other queriers somewhere in the mesh at least for Freifunk
Lübeck. Also adding these rules to be prepared to anyone intentionally
or unintentionally disabling these filters on his/her node.

There are a few devices which have more than one LAN interface (for example
some revision of the TL-WR941ND, which uses a DSA-based switch, so each
switch port has its own netdev.) On these devices we need a bridge for
mesh-on-lan (as the alternative of adding them to batman-adv individually
would need too many MAC addresses.)
While ath9k/ath10k devices can supprt VIFs with any combination of MAC addresses, there are also adapters which have a hardware MAC filter which only allows a few bits to differ. This commit changes the addresses of all VIFs to ony differ in the last 3 bits, which is required to support many Ralink/Mediatek based WLAN adapters.
Technically, the new addresses are generated by calculating an MD5 hash of the primary MAC address and using a part of this hash as a prefix for the MAC addresses.
The addresses (BSSIDs) of the AP VIFs are also reused for the LAN and WAN interfaces in mesh-on-LAN/WAN mode to reduce the number of needed addresses, and thus reduce the chance of collisions. This is not a problem as the MAC addresses of the AP VIFs are never used except as BSSID, and thus not seen by routing protocols like batman-adv.

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

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.
By introducing a new option -a in addition to -p this patch allows
controlling the on-link flag of announcements.
A prefix specified using -a will have the on-link flag set to zero
while a prefix specified using -p will retain its behaviour (i.e.
on-link flag set).
Example:
gluon-radvd -i local-node -p 2001:db8:aaaa:/64 -a 2001:db8:bbbb::/64
This will announce 2001:db8:aaaa::/64 with the on-link flag set and
2001:db8:bbbb::/64 with the flag unset.
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.
OpenWrt doesn't set the regdom unless a WLAN device is started. Explicitly set
the regdom in the setup mode to get the correct list of allowed txpower entries
in the planned LuCI module.
