The 'hwmode' setting has been replaced with 'band' in OpenWrt to add
support for newer bands outside of 2.4G and 5G. Adjust Gluon accordingly.
[Matthias Schiffer: rebased, extended commit message]
In meshes without VPN or supernodes, it may be desirable to connect a
router providing IPv4 addresses directly to a regular Gluon node. For
this to work, it was necessary to remove the gluon-ebtables-filter-ra-dhcp
package from the node, so the autoupdater also needed to be disabled.
To avoid this, make gluon-ebtables-filter-ra-dhcp disable the DHCPv4
filter rules when gw_mode is set to 'server'.
No solution is provided for RA/DHCPv6, but this seems less pressing for
local meshes, as nodes can already provide working IPv6 connectivity
by themselves through gluon-radvd.
The network.wireless status ubus call only returns the configured
channel from UCI, breaking the status page in outdoor mode, where the
configuration contains 'auto' instead of a number.

Closes#2336
In js `return` does behave like `continue` in a forEach() iteration.
The fixed function was intended to return nothing on error and does so
now, instead of a shorter (useless) array like before.
Calling functions like recv() with a NULL buffer is not explicitly
allowed by the POSIX standard, so it must be avoided to be portable
across different libc implementations. Allocate an initial buffer before
handling requests, and also pass this buffer to the peek recv() call.
Fixes: 531937cf6f ("gluon-neighbour-info: fix broken output with large results")
This removes PKG_VERSION and PKG_RELEASE from most Makefiles, as the
value was never useful for Gluon packages; instead, PKG_VERSION is set
to 1 in gluon.mk.
It also removes two other weird definitions:
- gluon-iptables-clamp-mss-to-pmtu replicating the old PKG_VERSION logic
from gluon-core, but without the fixed PKG_BUILD_DIR to prevent
unnessary rebuilds
- gluon-hoodselector set GLUON_VERSION=3
Calling git describe directly breaks isolation between the build system
and packages. Replace this with proper .config variables, like we
already do for GLUON_RELEASE.
Also replace the PKG_VERSION hack with a static '1', as we do for other
packages - while having those version numbers in opkg was cute, it was
also entirely useless. Having a fixed PKG_VERSION allows us to remove
the PKG_BUILD_DIR override as well.
Currently a buffer with a fixed size of 8192 bytes is used. However the
result can potentially be larger, which leads to a truncated JSON
output on stdout. UDP packets, without compression and with IP
fragmentation, can be up to 64KiB large.
Instead of using a fixed size buffer on the stack ask the kernel first
about the size of the UDP data and allocate a buffer of appropriate size
on the heap before receiving the UDP data.

The address of the vpn interface is calculated in the style of
modified EUI-64, based on a virtual mac address. This virtual mac
address consists of 0x00 as first byte and the other five bytes
are taken from the first bytes of md5sum(base64 encoded public key).
The algorithm was taken by the ffmuc, with a slight difference. ffmuc
calculated the result of md5sum(base64 encoded public key + '\n')
which was interpreted as accidential fault and therefore dropped.
Example:
- Public-Key: "gP3VJnTTvnQut+z4O+m0N9RgMyXbgyUbUkF3E3TKX2w="
- Address: "fe80::02ca:b8ff:fedc:2eb3"
The following interfaces are used for wireguard:
- wg_mesh -> wireguard interface
- mesh-vpn -> vxlan iface on top of wg_mesh
If you use this new feature, make sure the NTP servers in your site
config are publicly reachable. This is necessary, since wireguard
requires correct time before the vpn connection is established.
Therefore gluon performs ntp time synchronisation via WAN before it
establishes the vpn connection. Therefore the NTP servers have to
be publicly reachable (and not only via mesh).
Before this commit, some *.po files contained the same translation
twice within the same file. While this did not led to errors in
gluon yet, it is still invalid. This commit fixes that and removes
the duplicates.
- Move site check for prefix4 and extra_prefixes6 to gluon-core, so the
rules don't need to be duplicated in several packages. This also fixes
gluon-respondd not checking extra_prefixes6 at all when
gluon-ebtables-source-filter is not installed as well.
- A redundant check for prefix6 is removed from gluon-l3roamd (this was
already checked by gluon-core)
- A separate check for prefix4 remains in gluon-client-bridge, as the
setting in mandatory there
Fixes the display of client counts, which are numbers and not strings
in the respondd data.
Fixes: 3a885a1b22 ("gluon-status-page: make "gateway nexthop" a link (#2278)")
Do not depend on the respondd-airtime module just to get the configured
channels. This removes the display of the frequency in addition to the
channel, as it is not readily available.
In addition, the translation string is improved to allow for text after
the channel number.
This code is usually running on an embedded CPU without FPU. In
addtition to its inefficience, the algorithm is also much harder to

Replace the logarithm formula with a simple loop.
Specify conffiles for our packages, so they aren't overwritten during

unintended to have different behaviour for opkg update and full firmware

The PHY lookup helper "find_phy_by_path" could not lookup the PHY name
for paths from multi-phy devices.
An example for such a path would be:
'1e140000.pcie/pci0000:00/0000:00:01.0/0000:02:00.0+1'
The integer after the plus (+) character determines the PHY index of the
specific device in relation to the PHY with the lowest index of the
device.
For example, if the device provides phy2 and phy3, the above path would
describe phy3. In case the device provides phy0 and phy1, it would
describe phy1.
Rewrite the "find_phy_by_path" function to support those paths as well
as regular device paths in a universal manner.

VoCores aren't exactly useful mesh nodes except for experimentation.
They certainly aren't worth maintaining a whole target, in particular
one that has a WLAN driver not used by any other target.
It was found that a one second timeout for nodeinfo data may be too low,
so that when a node is otherwise occupied that timeout may be reached
too often.
The nodeinfo query response is also vital to the status-page base

Simplify the individual form providers by always running reconfigure. This
also commits all UCI packages, so we can remove all tracking of UCI
sections from the wizard code.
Instead of returning a list of packages to commit, the providers just
save their settings directly. Explicit runs of upgrade scripts are
removed, as they are now run by reconfigure.
This add support for a write() method on sections, in addition to the
value and form level write(). write() is only called when the section is
valid and visible. In addition, write() is empty by default, so it can be
overridden more easily.

With batman-adv 2020.4 and the according backports to batman-adv v2019.2
several more bugs were found and fixed regarding the batman-adv
multicast optimizations feature.
Also a "wakeup-call" feature was added to the Linux bridge IGMP/MLD
snooping code in Gluon to work around issues with Android devices.
With batman-adv now at v2019.2, multicast-to-multi-unicasts conversion
is supported, too. Which means that even if there are a few outdated nodes
these and all other recipients will be served multicast packets via unicast,
too, as long as the sum of receiving nodes does not exceed the multicast
fanout setting (default: 16). If is exceeded, then batman-adv will revert
back to broadcast flooding automatically.
Long story short, with all these extra measures in place, let's reenable
the batman-adv multicast optimizations to reduce the layer 2 overhead
and in preparation for multicast applications in the future.
The default is enabled for this feature anyway, so removing the
"batctl multicast_mode 0" overwrite is sufficient.

This switches the used wireless daemons for OWE / SAE to the OpenSSL
flavors. The WolfSSL implementation currently seems to be broken.
THis switch may be reverted at a later point in time when hostapd /
wpa_supplicant implementations for WolfSSL have matured.
Specifications:
* SoC: MT7620A
* RAM: 64 MB DDR
* Flash: 8MB NOR SPI flash
* WiFi: MT7612E (5Ghz) and builtin MT7620A (2.4GHz)
* LAN: 1x100M
The -factory images can be flashed from the device's web
interface or via nmrpflash.
Both devices differ by a additional power outlet for the EX3800.
This patch has been tested on a EX3800 device.
This renames the local_client zone to loc_client, as local_clint exceeds
the maximum zone length allowed for firewall3, which is 11 bytes.
This worked previously due to firewall3 using unsafe string operations.
Now creation of the chain fails (latest OpenWrt master).
This allows running a respondd querier and map server behind a Gluon
node.
For instance at Freifunk Lübeck we now moved the map server
behind a Gluon VM and removed batman-adv and fastd from the
map server VM to reduce the maintenance work.
Increased multicast overhead should be minimal / non existent, as it is
unlikely to accidentally have respondd queriers running behind a Gluon
node.

The rewrite of the feature handling introduced multiple major bugs. One
of them was caused by the way Lua's logical operators work:
An expression of the form
_'autoupdater' and _'web-advanced'
would return 'web-advanced' rather than the boolean true when _ returned
both strings unchanged (because the features are enabled).
As entries with more than a single feature name in their expressions did
not set no_default, Gluon would then attempt to add gluon-web-advanced to
the package selection, as web-advanced is a "pure" feature.
To fix this, and get rid of the annoying nodefault, separate handling of
"pure" feature and handling of logical expressions into two separate
functions, called feature() and when(). To simplify the feature
definitions, the package list is now passed directly to these functions
rather than in a table with a single field 'packages'.
Fixes: ee5ec5afe5 ("build: rewrite features.sh in Lua")
The new options are CONFIG_GLUON_AUTOUPDATER_BRANCH and
CONFIG_GLUON_AUTOUPDATER_ENABLED and allow to control the default branch
and default enable status separately.
The `or ''` fallback in targets/generic is removed, as GLUON_ENV will

This commit changes the behavior for the wan-dnsmasq to read the
interfaces to update the DNS servers on from flag-files.
This way, external custom packages which add a custom VPN WAN interface
can update the DNS server gluon is using for WAN resolving.
On lantiq, the default WAN ifname is 'dsl0' even on devices that have a
separate WAN port. At least on devices using swconfig we can override
this with the switch port labelled as 'wan'.
With very bad timing, it is possible that the teardown script of a
gluon_mesh interface runs when bat0 was just created, but primary0 is not
yet added to it. Although there is no hardif to remove in this case,
bat0 will still be deleted, because there is no hardif in bat0.
Disable the interface removal logic by passing `-M` to `batctl interface`.
There is no setting to explicitly enable mesh interfaces in the config
wizard, so we need to enable mesh interfaces by default when the outdoor
mode is disabled (unless site.conf dictates otherwise).
The simplest way to achieve this is to delete the 5GHz mesh interface
sections when outdoor mode is disabled: 200-wireless would delete and
recreate them a moment later anyways, but by deleting them earlier we
ensure that the disabled status is initialized from site.conf again.
Because is_disabled() was always returning true or false, the
first_non_nil() would never actually check the default setting from
site.conf. This was broken since v2017.1.

The interfaces should always exist and just be disabled when outdoor

necessary after enabling or disabling the ourdoor mode to make the mesh
VIF options appear or disappear.
Instead of relying on the existence of interface sections only (which is
still used for the case of interface types that are not configured at
all in the site config), add a proper dependency.
This fixes section visiblity with enabled outdoor mode after the following

As a partial fix to #496, do not touch the MAC address of the WAN

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

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.

This adds a helper method, which determines if the current platform

WPA3 is supported if
- the device is not in the featureset category "tiny"
- the WiFi driver supports 802.11w management frame protection
The gluon-wireless-encryption package selects a WPA3 supporting
hostapd package as a dependency and stores the information, which
encryption method is supported to the device.
This package adds support for SAE on 802.11s mesh connections.
Enabling this package will require all 802.11s mesh connections
to be encrypted using the SAE key agreement scheme. The security
of SAE relies upon the authentication through a shared secret.
In the context of public mesh networks a shared secret is an
obvious oxymoron. Still this functionality provides an improvement
over unencrypted mesh connections in that it protects against a
passive attacker who did not observe the key agreement. In addition
Management Frame Protection (802.11w) gets automatically enabled on
mesh interfaces to prevent protocol-level deauthentication attacks.
If `wifi.mesh.sae` is enabled a shared secret will automatically be
derived from the `prefix6` variable. This is as secure as it gets
for a public mesh network.
For *private* mesh networks `wifi.mesh.sae_passphrase` should be
set to your shared secret.
