Lech Perczak 0eebc6f0dd ath79: support Ruckus ZoneFlex 7341/7343/7363
Ruckus ZoneFlex 7363 is a dual-band, dual-radio 802.11n 2x2 MIMO enterprise
access point. ZoneFlex 7343 is the single band variant of 7363
restricted to 2.4GHz, and ZoneFlex 7341 is 7343 minus two Fast Ethernet
ports.

Hardware highligts:
- CPU: Atheros AR7161 SoC at 680 MHz
- RAM: 64MB DDR
- Flash: 16MB SPI-NOR
- Wi-Fi 2.4GHz: AR9280 PCI 2x2 MIMO radio with external beamforming
- Wi-Fi 5GHz: AR9280 PCI 2x2 MIMO radio with external beamforming
- Ethernet 1: single Gigabit Ethernet port through Marvell 88E1116R gigabit PHY
- Ethernet 2: two Fast Ethernet ports through Realtek RTL8363S switch,
  connected with Fast Ethernet link to CPU.
- PoE: input through Gigabit port
- Standalone 12V/1A power input
- USB: optional single USB 2.0 host port on the -U variants.

Serial console: 115200-8-N-1 on internal H1 header.
Pinout:

H1 ----------
   |1|x3|4|5|
   ----------

Pin 1 is near the "H1" marking.
1 - RX
x - no pin
3 - VCC (3.3V)
4 - GND
5 - TX

Installation:
- Using serial console - requires some disassembly, 3.3V USB-Serial
  adapter, TFTP server, and removing a single PH1 screw.

0. Connect serial console to H1 header. Ensure the serial converter
   does not back-power the board, otherwise it will fail to boot.

1. Power-on the board. Then quickly connect serial converter to PC and
   hit Ctrl+C in the terminal to break boot sequence. If you're lucky,
   you'll enter U-boot shell. Then skip to point 3.
   Connection parameters are 115200-8-N-1.

2. Allow the board to boot.  Press the reset button, so the board
   reboots into U-boot again and go back to point 1.

3. Set the "bootcmd" variable to disable the dual-boot feature of the
   system and ensure that uImage is loaded. This is critical step, and
   needs to be done only on initial installation.

   > setenv bootcmd "bootm 0xbf040000"
   > saveenv

4. Boot the OpenWrt initramfs using TFTP. Replace IP addresses as needed.
   Use the Gigabit interface, Fast Ethernet ports are not supported
   under U-boot:

   > setenv serverip 192.168.1.2
   > setenv ipaddr 192.168.1.1
   > tftpboot 0x81000000 openwrt-ath79-generic-ruckus_zf7363-initramfs-kernel.bin
   > bootm 0x81000000

5. Optional, but highly recommended: back up contents of "firmware" partition:

   $ ssh root@192.168.1.1 cat /dev/mtd1 > ruckus_zf7363_fw_backup.bin

6. Copy over sysupgrade image, and perform actual installation. OpenWrt
   shall boot from flash afterwards:

   $ ssh root@192.168.1.1
   # sysupgrade -n openwrt-ath79-generic-ruckus_zf7363-squashfs-sysupgrade.bin

   After unit boots, it should be available at the usual 192.168.1.1/24.

Return to factory firmware:

1. Copy over the backup to /tmp, for example using scp
2. Unset the "bootcmd" variable:
   fw_setenv bootcmd ""
3. Use sysupgrade with force to restore the backup:
   sysupgrade -F ruckus_zf7363_backup.bin
4. System will reboot.

Quirks and known issues:
- Fast Ethernet ports on ZF7363 and ZF7343 are supported, but management
  features of the RTL8363S switch aren't implemented yet, though the
  switch is visible over MDIO0 bus. This is a gigabit-capable switch, so
  link establishment with a gigabit link partner may take a longer time
  because RTL8363S advertises gigabit, and the port magnetics don't
  support it, so a downshift needs to occur. Both ports are accessible
  at eth1 interface, which - strangely - runs only at 100Mbps itself.
- Flash layout is changed from the factory, to use both firmware image
  partitions for storage using mtd-concat, and uImage format is used to
  actually boot the system, which rules out the dual-boot capability.
- Both radio has its own EEPROM on board, not connected to CPU.
- The stock firmware has dual-boot capability, which is not supported in
  OpenWrt by choice.
  It is controlled by data in the top 64kB of RAM which is unmapped,
  to avoid the interference in the boot process and accidental
  switch to the inactive image, although boot script presence in
  form of "bootcmd" variable should prevent this entirely.
- On some versions of stock firmware, it is possible to obtain root shell,
  however not much is available in terms of debugging facitilies.
  1. Login to the rkscli
  2. Execute hidden command "Ruckus"
  3. Copy and paste ";/bin/sh;" including quotes. This is required only
     once, the payload will be stored in writable filesystem.
  4. Execute hidden command "!v54!". Press Enter leaving empty reply for
     "What's your chow?" prompt.
  5. Busybox shell shall open.

- There is second method to achieve root shell, using command injection
  in the web interface:
  1. Login to web administration interface
  2. Go to Administration > Diagnostics
  3. Enter |telnetd${IFS}-p${IFS}204${IFS}-l${IFS}/bin/sh into "ping"
     field
  4. Press "Run test"
  5. Telnet to the device IP at port 204
  6. Busybox shell shall open.
