Flashing instructions:
======================

Various methods can be used to install the actual image on the flash.
Two easy ones are:

ap51-flash
----------

The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.

initramfs from TFTP
-------------------

The serial console must be used to access the u-boot shell during bootup.
It can then be used to first boot up the initramfs image from a TFTP server
(here with the IP 192.168.1.21):

    setenv serverip 192.168.1.21
    setenv ipaddr 192.168.1.1
    tftpboot 0c00000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr

The actual sysupgrade image can then be transferred (on the LAN port) to
the device via

    scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/

On the device, the sysupgrade must then be started using

    sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

Gluon image name change
=======================

The device had the image name "openmesh-om2phsv3" in older versions of Gluon.
This had to be changed with the new name in the device trees of the ath79
device tree.

properly boot the flashed image and to support dual-boot (primary +
recovery image). Unfortunately, the name of the mtd device in mtdparts is
still using the legacy name "ar7240-nor0" which must be supplied using the
Linux-specfic DT parameter linux,mtd-name to overwrite the generic name
"spi0.0".

It can then be used to first boot up the initramfs image from a TFTP server
(here with the IP 192.168.1.21):

    setenv serverip 192.168.1.21
    setenv ipaddr 192.168.1.1
    tftpboot 0c00000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr

The actual sysupgrade image can then be transferred (on the LAN port) to the
device via

    scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/

On the device, the sysupgrade must then be started using

    sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

Gluon image name change
=======================

The device had the image name "openmesh-mr600" in older versions of Gluon.
This had to be changed with the new name in the device trees of the ath79
device tree.

Device specifications:
======================

* Qualcomm/Atheros QCA9558 ver 1 rev 0
* 720/600/240 MHz (CPU/DDR/AHB)
* 128 MB of RAM
* 16 MB of SPI NOR flash
  - 2x 7 MB available; but one of the 7 MB regions is the recovery image
* 2T2R 2.4 GHz Wi-Fi (11n)
* 2T2R 5 GHz Wi-Fi (11ac)
* multi-color LED (controlled via red/green/blue GPIOs)
* 1x GPIO-button (reset)
* external h/w watchdog (enabled by default))
* TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX)
* 2x ethernet
  - eth0
    + Label: Ethernet 1
    + AR8035 ethernet PHY (RGMII)
    + 10/100/1000 Mbps Ethernet
    + 802.3af POE
    + used as WAN interface
  - eth1
    + Label: Ethernet 2
    + AR8035 ethernet PHY (SGMII)
    + 10/100/1000 Mbps Ethernet
    + used as LAN interface
* 1x USB
* internal antennas

Flashing instructions:
======================

Various methods can be used to install the actual image on the flash.
Two easy ones are:

ap51-flash
----------

The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.

initramfs from TFTP
-------------------

The serial console must be used to access the u-boot shell during bootup.
It can then be used to first boot up the initramfs image from a TFTP server
(here with the IP 192.168.1.21):

    setenv serverip 192.168.1.21
    setenv ipaddr 192.168.1.1
    tftpboot 0c00000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr

The actual sysupgrade image can then be transferred (on the LAN port) to the
device via

    scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/

On the device, the sysupgrade must then be started using

    sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

With Babel, wired meshing cannot run on the same logical interface as
non-mesh traffic, so using VXLAN is mandatory.

fastd: add L2TP offload support

treewide: Replace xhtml content type with html, remove xhtml workaround, replace self closing tags

A section can be marked as preseved by setting the gluon_preserve option
to 1. In addition the following conditions must hold:

- The preserved section must not already exist after OpenWrt's and
  Gluons setup scripts run. Modifying existing sections is currently
  unsupported.
- Preserved sections must be named, so it can be detected whether a
  section conflicts with a preexisting one.

Allow interface names to change on updates to handle hwconfig -> DSA and
similar migrations.

On devices with only a single interface, a sysconfig single_ifname is
created instead of wan_ifname or lan_ifname to allow separate
configuration in site.conf.

With the new role-based interface configuration, it would be better to
rename the wan/wan6 interfaces to uplink/uplink6, but that would cause
unnecessary churn for the firewall configuration, so it is left for a
later update.

As all interfaces with the 'uplink' role are in the br-wan bridge, it is
not possible to assign these to the 'mesh' role independently - instead,
br-wan is added as a mesh interface as soon as a single interface has
both the 'uplink' and 'mesh' roles. The UCI section for this
configuration is now called 'mesh_uplink' instead of 'mesh_wan'.

For all interfaces that have the 'mesh', but not the 'uplink' role a
second configuration 'mesh_other' is created. If there is more than one
such interface, all these interfaces are bridged as well (creating a
bridge 'br-mesh_other'). This replaces the 'mesh_lan' section with its
optional 'br-mesh_lan' bridge, but can also include interfaces that were
not considered "LAN" when interfaces roles are modified (via site.conf
or manually).

The new configuration generates sections iface_single/lan/wan in
/etc/config/gluon. These sections usually refer to a sysconfig-controlled
interface list, but adding custom sections with verbatim interfaces names
is also possible.

Each interface section contains a list of roles. The supported roles are
'client', 'uplink' and 'mesh'. Multiple roles can be configured on the
same interface (for example the old 'mesh_on_wan' setting would become
'uplink'+'mesh').

'client' is subsumed by any other role configured on the same interface
('client'+'mesh' is equivalent to 'mesh'). This property is important, as
it allows the Wired Mesh settings in gluon-web-network to simply add and
remove the mesh role without having to care what other roles are set -
so in the default setup, this would switch between 'client' and
'client'+'mesh' for the LAN interface.

By default, the WAN interface has role 'uplink' and the LAN interface
'client'; if only a single interface exists, the roles from the WAN
interface are used by default. The default for each of the three
interfaces (WAN/LAN/single) can be changed separated in site.conf,
superseding the old mesh_on_wan, mesh_on_lan and single_as_lan settings.

Do not write files when the content is unchanged.

Avoids a few unnecessary filesystem writes when resetting ifname
sysconfigs on each upgrade.

The stdout output of gluon-web scripts is directly sent to uhttpd,
becoming a part of the HTML output or even replacing HTTP status or
headers. The output of gluon-reconfigure is not supposed to end up
there.

While we're at it, also add an exec to avoid an unnecessary shell
process.

The OpenLayers JS/CSS download URL is dead. Update it to make the map
work again:

- Update from OpenLayers 5.2.0 to 5.3.0
- Switch from the obsolete rawgit.com URL to jsdelivr.net (rawgit.com
  was only redirecting to jsdelivr.net for the last few years anyways)
- Set a fixed commit in the URL, so the URL doesn't become outdated again

Prevents spurious build failures.
