commit 33b72b8e0f
"ar8216: adjust ATU flushing in case of link changes"
introduced portwise flushing on link down events. Now the ARL table could
be in a chaotic state after boot where ar8xxx_sw_get_arl_table looped
forever (depending on the entries collected while booting).

This patch adds supports for the WNR2000v1 board with 4MB flash, and
produces device-specific factory, rootfs, and sysupgrade files for the
WNR2000v1. This board is errorneously claimed as supported on the OpenWRT
wiki as AP81, but AP81 image would not work because of APT81 image
requiring having 8MB of flash, while WNR2000v1 has only 4MB.
The image requires the u-boot bootloader to be modified to fuhry's
bootloader first.
Short specification:
- CPU: Atheros AR9132
- 4x 10/100 Mbps Ethernet, 1x WAN 10/100 Mbps
- 4 MB of Flash
- 32 MB of RAM
- UART header (J1) on board
- 1x button
Factory/Initial flash instructions:
- Set up a TFTP server on your local machine.
- Download the uImage for ar71xx-generic and the rootfs image for
ar71xx-generic-wnr2000 and save in the tftp server root.
- Gain serial access to the router via the UART port (telnetenable over
the network only won't work!).
- Upgrade the u-boot bootloader to fuhry's version by running the
script: http://fuhry.com/b/wnr2000/install-repart.sh
- When the router restarts, interrupt u-boot and gain access to u-boot command line.
- Repartititon the board and flash initial uImage and rootfs as follow.
Commands to type in u-boot:
# tells u-boot that we have a tftp server on 192.168.1.10
setenv serverip 192.168.1.10
# tells u-boot that the router should take the address 192.168.1.1
setenv ipaddr 192.168.1.1
# erase the region from 0x050000-0x3f0000
erase 0xbf050000 +0x3A0000
# loads sqfs.bin on TFTP server, and put it to memory address 0x81000000
tftpboot 0x81000000 sqfs.bin
# it will tell you the length of sqfs.bin in hex, let's say ZZZZZZ
# copy bit by bit 0xZZZZZZ bytes from offset 0x050000
cp.b 0x81000000 0xbf050000 0xZZZZZZ
# same to the uImage.bin, write it right next to sqfs.bin
# again, 0xYYYYYY is the length that tftpboot reports
tftpboot 0x81000000 uImage.bin
cp.b 0x81000000 0xbf2a0000 0xYYYYYY
# We need to tell the kernel what board it is booting into, and where to find the partitions
setenv bootargs "board=WNR2000 console=ttyS0,115200 mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,3712k(firmware),64k(art)ro rootfstype=squashfs,jffs2 noinitrd"
# Tell u-boot where to find the uImage
setenv bootcmd "bootm 0xbf2a0000"
# Tell u-boot to save parameters to the u-boot-env partitions
saveenv
# Reset the board
reset
Tested on:
- WNR2000v1 board.
- Initial flash works.
Known bugs:
- I don't know why factory image doesn't work on initial flash on stock
firmware in u-boot recovery mode while it should.
- Sysupgrade does not yet work, if you do -f it will mess up your
installation (requiring a reinstall of sqfs and uImage).

CHROMIUM: drivers: ar8216: prevent device duplication in ar8xxx_dev_list
If probe is called twice, once for PHY0 and a second time for PHY4,
the same switch device will be added twice to ar8xxx_dev_list, while
supposedly this list should have one element per hardware switch present
in the system.
While no negative impact have been observed, it does happen if a
platform instanciates these two PHYs from device-tree, as an example.

The commit "generic: ar8216: add sanity check to ar8216_probe"
(774da6c7a4) stated that PHY IDs
should be checked at address 0-4. However, the PHY 4 was
never check by the loop. This patch extends the check to be
similar to the Atheors SDK. It tries all 4 ports and skips
unconnected PHYs if necessary. If it cannot find any familiar
PHYs, it will prevent the phy driver from initializing.
This patch is necessary for the C-60. It doesn't have a
PHY at port 3, so this caused the check in ar8xxx_is_possible
to fail. As a result, the ethernet ports on the C-60 didn't
work.

Some devices (like the Cisco Meraki Z1 Cloud Managed Teleworker Gateway)
need to be able to initialize the PCIe wifi device. Normally, this is done
during the early stages of booting linux, because the necessary init code
is read from the memory mapped SPI and passed to pci_enable_ath9k_fixup.
However,this isn't possible for devices which have the init code for the
Atheros chip stored on NAND in an UBI volume. Hence, this module can be
used to initialze the chip when the user-space is ready to extract the
init code.
Martin Blumenstingl made a few fixes and added support for lantiq:
kernel: owl-loader: add support for OWL emulation PCI devices
kernel: owl-loader: don't re-scan the bus when ath9k_pci_fixup failed
kernel: owl-loader: use dev_* instead of pr_* logging functions
kernel: owl-loader: auto-generate the eeprom filename as fallback
kernel: owl-loader: add a debug message when swapping the eeprom data
kernel: owl-loader: add missing newlines in log messages
kernel: owl-loader: add support for the lantiq platform
These patches have been integrated. Thanks!

Some devices (e.g. Tenda AC9 based on BCM47189B0) have BCM53125 with

The swconfig kernel infrastructure fails to do any permissions checks when
changing settings. As such an ordinary user account on a device with a
switch can change switch settings without any special permissions.
Routers generally have few non-admin users so this isn't a big hole, but it
is a security hole. Likely the greatest danger is for multifunction devices
which have a lot of extra daemons, compromising a low-security daemon would
allow one to modify switch settings and cause the router/switch to appear to
lock-up (or cause other sorts of troublesome nyetwork behavior).
Implement a check for CAP_NET_ADMIN in swconfig_set_attr() and deny any
requests originating from user contexts lacking this capability.

The default TTL for address resolution table entries is 5 minutes
for all members of the AR8216 family. This can cause issues if
e.g. Wifi clients roam to another AP and their MAC appears on
another switch port suddenly. Then the client may not be reachable
until the old ARL entry expires.
I would have expected the switch to invalidate old entries if it
detects the same MAC on another port. But that's not the case.
Therefore make the TTL for ARL entries configurable.
The effective TTL will always be a multiple of 7 seconds.
