The netdev() lookup is confusing to use: whenever a interface does not
exist during boot (for example VLAN) or when the address is overridden
from board.json (which is not obvious at all), it will yield either no
address, or a different address than expected.
To avoid this confusion, using board.json-based interface() is
preferable. This converts all uses of netdev() to the corresponding
lan/wan lookups, except for the final fallback for eth0.
- Replace misnamed, closure-returning sysfs() to a reusable read() function
- Rename eth() to netdev(), pass full interface name
- Rename board() to interface()
- Split reuable get_netdev_addr() out of netdev()
gsub() returns the number of matches as its second return value. This
was unintendedly passed through by the util functions trim() and
node_id(). It can be presumed that this had no effect in practice, but
it can lead to surprising output when passing values to print() for
debugging.
This adds a helper method, which determines if the current platform
supports WPA3 or not.
WPA3 is supported if
- the device is not in the featureset category "tiny"
- the WiFi driver supports 802.11w management frame protection
Remove a lot of redundant code by switching to a match table listing
the targets and boards for each candidate for the primary MAC interface.
In addition, we add some flexiblity by allow to switch out the sysfs file
data source for the MAC address.
mac_to_ip() calculates an ipv6 address from a mac address according to
RFC 4291. For wireguard we have to use specially crafted addresses that
must be unique. This allows calculating such unique mac-based addresses
by allowing to optionally specifying the bytes to be inserted into the
address.
This is a fix for the broken ingress traffic-shaping in gluon v2018.2.2
and possibly earlier.
For ingress traffic shaping the kernel option NET_ACT_POLICE is needed.
Before this patch there was no dependency to this. Neither in
gluon_core, gluon-mesh-vpn-core nor in the package.
This patch adds this dependency.

Fixes#1790
The is_outdoor function is placed inside the gluon.platform module, not
the platform_info module. Currently, the outdoor-mode wizard component
and the upgrade script fail due to nil-value calls.
Add the `wifi5.outdoor_chanlist` site configuration that
allows specifying an outdoor channel range that can be
switched to for regulatory compliance.
Upon enabling the outdoor option the device will
- configure the `outdoor_chanlist` on all 5 GHz radios
- which may enable DFS/TPC, based on the regulatory domain
- disable ibss/mesh on the 5 GHz radio, as DFS *will*
break mesh connections
- allow for htmode reconfiguration on 5 GHz radios
The outdoor option can be toggled from
- Advanced Settings
- W-LAN
- Outdoor Installation
The `preserve_channel` flag overrules the outdoor channel
selection.
The device is broken until the next release. The LEDs are currently not
working (fixed in current OpenWRT master).
Also give a brief explanation about the BROKEN status being dependent on
the WiFi chip used and not the SoC family in general.
Gluon has multiple ways to obtain unique MAC-addresses. They are either
provided by the WiFi driver or derived from the primary MAC-address.
Quoting the same file:
> It's necessary that the first 45 bits of the MAC address don't
> vary on a single hardware interface, since some chips are using
> a hardware MAC filter. (e.g 'rt305x')
This currently fails in case the rt35xx based chips mac address differs
from the primary MAC. In this case, the MAC address for the client0 radio
(vif 1) comes from the WiFi driver. As there is only a single
MAC-address provided by '/sys/class/ieee80211/phyX/addresses' but the
MAC-address for mesh 0 (vif 2) is derived from the Node-ID, resulting in
different first 45 bits. The WiFi won't come up altogether in this case.
This commit verifies at least 4 MAC-Addresses are provided by the WiFi
driver. If this is not the case, all MAC-addresses are derived from the
primary MAC. This way, affected radios are working correctly.
This commit distributes dualband radios evenly on 2.4 GHz and 5GHz with
2.4 GHz being prioritised higher than 5 GHz. This means in case a device
has only a single radio and this radio supports operation in both bands,
it will be set to 2.4 GHz.

The device is marked as broken due to 64MB which might be insufficient
in certain environments.
This reverts commit b3d7011130.
with this change, DNS in batman-adv based networks is broken.
although the revert breaks babel based networks, this is not as big of a problem.
This device is a dual 5GHz device. It is recommended to manually change the
radio of the first device to the lower 5GHz channels and the second radio
to the upper 5GHz channels.
In multidomain setups, VXLAN is enabled by default, but can be disabled in
domain configs using the mesh/vxlan option. In single domain setups, the
mesh/vxlan option is mandatory.
The UCI option for legacy mode is removed.
Fixes#1364
dnsmasq's caching is severly broken and does not handle all answer records
equally. In particular, its cached answers are missing DNSKEY and DS
records, breaking DNSSEC validation on clients.
Remove the cache for now. It may return if dnsmasq is fixed or we switch to
a different resolver.
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.
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.
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.
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
config load implementation needs to changed only in a single place for
multi-domain support.
* gluon-core, gluon-client-bridge: introduce new firewall zone: local_client
* gluon-core: put clients in local_client zone, introduce drop-zone,
set dns-rules and zones
* gluon-respondd: allow respondd on mesh
* gluon-status-page-api: allow http input on mesh and client
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')
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).
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.

Some drivers (mt76) don't support arbitrary MAC addresses. Use the
addresses provided by the driver (avoiding the primary address) by default,
but fall back to our has-based scheme when the driver doesn't provide

bottom. Also all other mac addresses are calculated based on this address.

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.
