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.
Closes: #2090

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.
* build: target_config_lib: introduce concat_list helper
* build: rewrite features.sh in Lua
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.
* build: add luacheck support for package/features
Replace the ugly arrow shown in Firefox with a custom SVG arrow. Tested
and working in Firefox, Chrome and Edge. The arrow doesn't show in IE, but
the gluon-web-model JavaScript is already severely broken in IE, so we
don't care.
When the network connectivity is bad, routers may not appear in the
translation tables, or there may be no originator with TQ >0. Such

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).
200-wireless will add or remove the mesh network sections of
/etc/config/network. Commit this file, so the modified setting doesn't
get lost on reboot.
Fixes: #2048
Validation errors are mostly handled in the frontend (by displaying
invalid fields with a red background). There was some code left in the
backend for handling different kinds of errors, and returning custom
error messages from validate(), but the resulting value was not used
anywhere.
- Add a dependency array to section template
- Lift dependency handling from AbstractValue to Node
- Split resolve_depends() into a function handling dependencies of a
node itself (resolve_node_depends()), which now is used for all nodes,
and the existing recursive descent through the node tree
- When any node's dependencies are not satisfied, all descendents are
reset recursively, meaning that an option in a section that is hidden
will always be ignored, as if the option's own dependencies were
unsatisfied
Fixes: #1349
- If luasrcdiet fails for a Lua script, this is a bug that should be
noticed rather than including the unminified script
- Use .tmp suffix for temporary file rather than .o
- Replace chmod + stat + mv with simpler cp + rm to overwrite file while
preserving file mode
gluonutil_get_interface_lower() recursively determines the lower of an
interface until the base interface is found.
gluonutil_get_interface_type() tries do distinguish wired, wireless and
tunnel interfaces. For tunnel interfaces, TUN/TAP, L2TPETH and Wireguard
are supported at the moment.
- Rename obtain_if_addr() to get_linklocal_address()
- Pass buffer of size INET6_ADDRSTRLEN instead of the oversized NI_MAXHOST
- Check if an address is link-local before converting to a string
- Replace an incorrect use of strncmp() with strcmp()
- Return status to caller
- Streamline control flow
While we're at it, the function handle_neighbour(), which is one of the
callers of get_linklocal_address() is slightly cleaned up as well.
This switches hostapd variant used for SAE and OWE from hostapd-openssl
to hostapd-wolfssl.
The bug shich one broke the wolfssl implementation was resolved upstream
with commit 631c437a91c2 ("hostapd: backport wolfssl bignum fixes").
This particular commit also got backported to OpenWrt 19.07.
This allows for multiple mesh legs out of one box. Useful for offloaders
and networks using vlan for separate mesh transport.
Custom mesh interfaces in a VXLAN domain are otherwise firewalled.
This fixes#1479
This adds support for the beacon interval to be set on a per-band base.
This has the potential to reduce the amount of airtime used up for
sending beacon frames.
Separate wireless-related helper methods from the util module to a
new wireless module. This keeps them separated, as the amount of
wireless helpers increased in the past, justifying a separate module.
xt_CT was added to kmod-ipt-conntrack a while back. Update our
GLUON_SPECIALIZE_KERNEL rules accordingly.
When building xt_CT into the kernel, one of the symbols IP_NF_RAW and
IP6_NF_RAW must be enabled as well, even though there is no runtime
dependency when building as modules. The kernel grows by less than 1KB
even when both IP_NF_RAW and NETFILTER_XT_TARGET_CT are enabled, making
this change a (very slight) net win in both flash and RAM usage.
As a partial fix to #496, do not touch the MAC address of the WAN
interface when using VXLANs (as only the MAC address of the VXLAN
interface matters to batman-adv).
On PoE-powered devices, we usually want to use WAN for the setup mode.
As all outdoor devices are PoE-powered, we can reuse this function. This
switches the setup mode interface for new installations / after config
reset on a few devices that were missing in this list before.
The 'preserve' flag can be used to mark a peer so it is not removed or
modified on upgrades. In addition, groups containing preserved peers are
not removed.
Fixes: #557
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.
Allows reconfigurtion of remote syslog from within site.conf.
Conflicts with the gluon-web-logging package as user made changes
will be overwritten, because this package will reconfigure the syslog
destination on every upgrade.
Resolves#1845
Use the value of the `name` site.conf field as label (it was
accidentally unused before).
Our site.conf currently doesn't define a specific order for the branch
entries. To avoid changing branch orders, sort entries by this label.
Fixes: #1961
Register to 'reset' event on form element and make call to 'update' function
delayed in 'data-update' handler to allow the form values to update beforehand.
When using a form's 'reset' button, form field visibility was not updated.
This could lead to situations where a checkbox had to be toggled again
twice to display the detail text inputs. (Example taken from private
wifi package)
