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.
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.

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 issue was observed with a custom respondd provider.

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.

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
understand.
Replace the logarithm formula with a simple loop.
Specify conffiles for our packages, so they aren't overwritten during
opkg updates. While this only matters during development, it is
unintended to have different behaviour for opkg update and full firmware
updates.
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.

Delete all default network device sections upon first boot.
Only LAN & WAN networks are defined at this point. We are using the
legacy way of definiting bridges via the interface sections ifname
option.
The prior filtering was based upon a single device and didn't take into
consideration that DSA interface names can be named arbitrarily.

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
template, so that when it times out, the site will be turned in a broken
state, that it cannot recover from.
Fixes: #2256
A leading tab character usually marks recipe lines in Makefiles;
non-recipe lines must be indented using spaces.
The incorrect tab character doesn't seen to have caused any issues in
this case, but it should be fixed nonetheless, if only for consistency.
The file_contains_line helper function was not testing whether a file
exists or not prior attempting to read from it.
Add this check to circumvent errors on the private WiFi config in
case the hwflags file is missing.
