2374549916 ar8216: flush ARL table during reset after init_globals
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).

fd62fa752b ar71xx: Add support for Netgear WNR2000v1
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.

CHROMIUM: drivers: ar8216: hold ar8xxx_dev_list_lock during use_count--

It is possible for the remove() callback to run twice in parallel, which
could result into --use_count returning only 1 in both cases and the
rest of the unregistration path to never be reached.

This case has never been observed in practice, but we will fix
preventively to make the code more robust.

e9455c561d generic: ar8216: improve ar8xxx_is_possible check
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.

e9401a2335 kernel: owl-loader for delayed Atheros ath9k fixup
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!

cf6d9d97fb kernel: rename B53 symbols to avoid upstream kernel conflict
In kernel 4.7 there is upstreamed b53 driver using (mostly?) the same
symbols as our b53 does. Change our symbols so both drivers can coexist
in kernel tree.

1aca291214 kernel: mtdsplit: calculate kernel partition precisely for Seama
So far "kernel" partition didn't contain just a kernel. It also included
Seama header and meta data. This was making kernel update complex and it
wasn't trivial to read kernel size.
Fix it by making "kernel" parition contain just a kernel image.

442db0d6d8 kernel: deny swconfig set requests for unprivileged users
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.
