In case the limit_ingress or limit_egress options are not present in
gluon's mesh_vpn section the respondd provider compares a string literal
with a NULL pointer, crashing respondd.
Check both pointers prior to comparing them in order to mitigate this
issue.

This fully abstracts VPN methods, making gluon-mesh-vpn-fastd and
gluon-mesh-vpn-tunneldigger completely self-contained.
Provide a LUA interface for generic interacting with VPN methods in
gluon-mesh-vpn-core and web packages.
This also adds the ability to install tunneldigger and fastd to the same
image, selecting the VPN method based on the selected domain.

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.
Before this commit the decision whether a vxlan layer will be
introduced between the lower interface before the interface is
added to batman was inside the proto. Now the decision is moved
to the user of the proto.
Add a package for handling upgrade-scripts speific for the WAN radio
operation.
This way, the config mode interface can be removed seperately from the
core functionality to perform tasks on system upgrade. This can be
useful when the setup-mode is removed entirely for space preservation.
Allow the transmission of IPv6 multicast packets as long as they are not
flooded through the whole mesh.

Set the ifname for the WAN radio (Private WLAN) to wanX, X being the

All other radios created by Gluon already have their ifname defined
following this pattern.

The rudimentary flash size determination function expects the partition
for the devices firmware to be called "linux" while it is (since quite
some time) "firmware".
Fix this error to display available flash size as well as more useful
error message in case the uploaded firmware image exceeds the flash
space.

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 adds the OpenWrt label-mac device selection as the most preferred
fallback.
While this is only used on OpenWrt 19.07 for backports, we can also use
the label-mac device when backporting device support. This way, we have
to deal with less device-sepcific code downstream.

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
set all variables in GLUON_VARS, making previously non-existing
variables exist with an empty value.
We already have a proper message when the creation of an alias fails
because of a name conflict. Also add a message when the primary filename
of a domain config is already occupied by another domain's alias.
Also add an 'Error:' prefix to the existing message to easier to see.
Reorder scripts so that the mesh_lan interface is accounted for.
Two other firewall upgrade scripts (mesh-babel and l3roamd) are
reordered as well. While there seems to be no hard dependency at the
moment, it makes sense to run the basic setup first, also to avoid
problems with future changes.

This adds the wireless client count for 2.4GHz and 5 GHz radios to the
status page. Previously, only the total client count advertised by
the mesh protocol was visible.
This will hide the outdoor mode setting on compatible devices in case
the defined channels should be preserved.
Otherwise a user might be under the impression their device is compliant
with outdoor operation when in reality it still uses prohibited
channels.

The `features` file is converted to a Lua-based DSL.
A helper function `_` is used in the DSL; this will return the original
string for enabled features, and nil for disabled features. This allows
to use boolean operations on features without making the code too
verbose.
Besides having more readable and robust code, this also fixes the bug
that all files `packages/*/features` were evaluated instead of only
using the feature definitions of currently active feeds.

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.

With 11a3b56617 ("gluon-web-model: add dependency support for
sections"), a "reset" function was added to all model nodes. This
conflicts with the "reset" field of the Form object, making reset
buttons show labels like "function: 0xbb8d50" and possibly breaking form
processing when packages override the reset field.
The interfaces should always exist and just be disabled when outdoor
mode is enabled. Not creating them at all leads to an issue in the
advanced wifi settings where an additional reload of the page is
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
fix, and gives the user immediate feedback (allowing to disable outdoor
mode and enable meshing in a single step).
