c50ece58c4 kernel: backport switchdev fix for bridge in bridge configurations
This patch fixes the forwarding behavior of bridge in bridge
configurations with DSA.

Without it, the configuration of the upper bridge might overwrite
settings of the lower bridge. For example, a vlan-aware bridge
with DSA interfaces in it might be offloaded to the DSA hardware. If the
bridge interface itself gets slave of a different bridge without vlan
filtering, the vlan filtering setting of the lower bridge is overwritten
by the upper bridge, which results in an incorrect hardware
configuration.

This was backported from kernel 5.7.

In the current state, nvmem cells are only detected on platform device.
To quickly fix the problem, we register the affected problematic driver
with the of_platform but that is more an hack than a real solution.
Backport from net-next the required patch so that nvmem can work also
with non-platform devices and rework our current patch.
Drop the mediatek and dsa workaround and rework the ath10k patches.
Rework every driver that use the of_get_mac_address api.

9ffa2f8193 kernel: Activate FORTIFY_SOURCE for MIPS kernel 5.4
CONFIG_FORTIFY_SOURCE=y is already set in the generic kernel
configuration, but it is not working for MIPS on kernel 5.4, support for
MIPS was only added with kernel 5.5, other architectures like aarch64
support FORTIFY_SOURCE already since some time.

This patch adds support for FORTIFY_SOURCE to MIPS with kernel 5.4,
kernel 5.10 already supports this and needs no changes.

This backports one patch from kernel 5.5 and one fix from 5.8 to make
fortify source also work on our kernel 5.4.

The changes are not compatible with the
306-mips_mem_functions_performance.patch patch which was also removed
with kernel 5.10, probably because of the same problems. I think it is
not needed anyway as the compiler should automatically optimize the
calls to memset(), memcpy() and memmove() even when not explicitly
telling the compiler to use the build in variant.

This increases the size of an uncompressed kernel by less than 1 KB.

3888fa7880 kernel: 5.4: import wireguard backport
Rather than using the clunky, old, slower wireguard-linux-compat out of
tree module, this commit does a patch-by-patch backport of upstream's
wireguard to 5.4. This specific backport is in widespread use, being
part of SUSE's enterprise kernel, Oracle's enterprise kernel, Google's
Android kernel, Gentoo's distro kernel, and probably more I've forgotten
about. It's definately the "more proper" way of adding wireguard to a
kernel than the ugly compat.h hell of the wireguard-linux-compat repo.
And most importantly for OpenWRT, it allows using the same module
configuration code for 5.10 as for 5.4, with no need for bifurcation.

These patches are from the backport tree which is maintained in the
open here: https://git.zx2c4.com/wireguard-linux/log/?h=backport-5.4.y
I'll be sending PRs to update this as needed.

59d065c9f8 ramips: add support for ZTE MF283+
ZTE MF283+ is a dual-antenna LTE category 4 router, based on Ralink
RT3352 SoC, and built-in ZTE P685M PCIe MiniCard LTE modem.

Hardware highlighs:
- CPU: MIPS24KEc at 400MHz,
- RAM: 64MB DDR2,
- Flash: 16MB SPI,
- Ethernet: 4 10/100M port switch with VLAN support,
- Wireless: Dual-stream 802.11n (RT2860), with two internal antennas,
- WWAN: Built-in ZTE P685M modem, with two internal antennas and two
  switching SMA connectors for external antennas,
- FXS: Single ATA, with two connectors marked PHONE1 and PHONE2,
  internally wired in parallel by 0-Ohm resistors, handled entirely by
  internal WWAN modem.
- USB: internal miniPCIe slot for modem,
  unpopulated USB A connector on PCB.
- SIM slot for the WWAN modem.
- UART connector for the console (unpopulated) at 3.3V,
  pinout: 1: VCC, 2: TXD, 3: RXD, 4: GND,
  settings: 57600-8-N-1.
- LEDs: Power (fixed), WLAN, WWAN (RGB),
  phone (bicolor, controlled by modem), Signal,
  4 link/act LEDs for LAN1-4.
- Buttons: WPS, reset.

Installation:
As the modem is, for most of the time, provided by carriers, there is no
possibility to flash through web interface, only built-in FOTA update
and TFTP recovery are supported.

There are two installation methods:
(1) Using serial console and initramfs-kernel - recommended, as it
allows you to back up original firmware, or
(2) Using TFTP recovery - does not require disassembly.

(1) Using serial console:
To install OpenWrt, one needs to disassemble the
router and flash it via TFTP by using serial console:
- Locate unpopulated 4-pin header on the top of the board, near buttons.
- Connect UART adapter to the connector. Use 3.3V voltage level only,
  omit VCC connection. Pin 1 (VCC) is marked by square pad.
- Put your initramfs-kernel image in TFTP server directory.
- Power-up the device.
- Press "1" to load initramfs image to RAM.
- Enter IP address chosen for the device (defaults to 192.168.0.1).
- Enter TFTP server IP address (defaults to 192.168.0.22).
- Enter image filename as put inside TFTP server - something short,
  like firmware.bin is recommended.
- Hit enter to load the image. U-boot will store above values in
  persistent environment for next installation.
- If you ever might want to return to vendor firmware,
  BACK UP CONTENTS OF YOUR FLASH NOW.
  For this router, commonly used by mobile networks,
  plain vendor images are not officially available.
  To do so, copy contents of each /dev/mtd[0-3], "firmware" - mtd3 being the
  most important, and copy them over network to your PC. But in case
  anything goes wrong, PLEASE do back up ALL OF THEM.
- From under OpenWrt just booted, load the sysupgrade image to tmpfs,
  and execute sysupgrade.

(2) Using TFTP recovery
- Set your host IP to 192.168.0.22 - for example using:
sudo ip addr add 192.168.0.22/24 dev <interface>
- Set up a TFTP server on your machine
- Put the sysupgrade image in TFTP server root named as 'root_uImage'
  (no quotes), for example using tftpd:
  cp openwrt-ramips-rt305x-zte_mf283plus-squashfs-sysupgrade.bin /srv/tftp/root_uImage
- Power on the router holding BOTH Reset and WPS buttons held for around
  5 seconds, until after WWAN and Signal LEDs blink.
- Wait for OpenWrt to start booting up, this should take around a
  minute.

Return to original firmware:
Here, again there are two possibilities are possible, just like for
installation:
(1) Using initramfs-kernel image and serial console
(2) Using TFTP recovery

(1) Using initramfs-kernel image and serial console
- Boot OpenWrt initramfs-kernel image via TFTP the same as for
  installation.
- Copy over the backed up "firmware.bin" image of "mtd3" to /tmp/
- Use "mtd write /tmp/firmware.bin /dev/mtd3", where firmware.bin is
  your backup taken before OpenWrt installation, and /dev/mtd3 is the
  "firmware" partition.

(2) Using TFTP recovery
- Follow the same steps as for installation, but replacing 'root_uImage'
  with firmware backup you took during installation, or by vendor
  firmware obtained elsewhere.

A few quirks of the device, noted from my instance:
- Wired and wireless MAC addresses written in flash are the same,
  despite being in separate locations.
- Power LED is hardwired to 3.3V, so there is no status LED per se, and
  WLAN LED is controlled by WLAN driver, so I had to hijack 3G/4G LED
  for status - original firmware also does this in bootup.
- FXS subsystem and its LED is controlled by the
  modem, so it work independently of OpenWrt.
  Tested to work even before OpenWrt booted.
  I managed to open up modem's shell via ADB,
  and found from its kernel logs, that FXS and its LED is indeed controlled
  by modem.
- While finding LEDs, I had no GPL source drop from ZTE, so I had to probe for
  each and every one of them manually, so this might not be complete -
  it looks like bicolor LED is used for FXS, possibly to support
  dual-ported variant in other device sharing the PCB.
- Flash performance is very low, despite enabling 50MHz clock and fast
  read command, due to using 4k sectors throughout the target. I decided
  to keep it at the moment, to avoid breaking existing devices - I
  identified one potentially affected, should this be limited to under
  4MB of Flash. The difference between sysupgrade durations is whopping
  3min vs 8min, so this is worth pursuing.

In vendor firmware, WWAN LED behaviour is as follows, citing the manual:
- red - no registration,
- green - 3G,
- blue - 4G.
Blinking indicates activity, so netdev trigger mapped from wwan0 to blue:wwan
looks reasonable at the moment, for full replacement, a script similar to
"rssileds" would need to be developed.

Behaviour of "Signal LED" in vendor firmware is as follows:
- Off - no signal,
- Blinking - poor coverage
- Solid - good coverage.

A few more details on the built-in LTE modem:
Modem is not fully supported upstream in Linux - only two CDC ports
(DIAG and one for QMI) probe. I sent patches upstream to add required device
IDs for full support.
The mapping of USB functions is as follows:
- CDC (QCDM) - dedicated to comunicating with proprietary Qualcomm tools.
- CDC (PCUI) - not supported by upstream 'option' driver yet. Patch
  submitted upstream.
- CDC (Modem) - Exactly the same as above
- QMI - A patch is sent upstream to add device ID, with that in place,
  uqmi did connect successfully, once I selected correct PDP context
  type for my SIM (IPv4-only, not default IPv4v6).
- ADB - self-explanatory, one can access the ADB shell with a device ID
  added to 51-android.rules like so:

SUBSYSTEM!="usb", GOTO="android_usb_rules_end"
LABEL="android_usb_rules_begin"
SUBSYSTEM=="usb", ATTR{idVendor}=="19d2", ATTR{idProduct}=="1275", ENV{adb_user}="yes"
ENV{adb_user}=="yes", MODE="0660", GROUP="plugdev", TAG+="uaccess"
LABEL="android_usb_rules_end"

While not really needed in OpenWrt, it might come useful if one decides to
move the modem to their PC to hack it further, insides seem to be pretty
interesting. ADB also works well from within OpenWrt without that. O
course it isn't needed for normal operation, so I left it out of
DEVICE_PACKAGES.

920eaab1d8 kernel: DSA roaming fix for Marvell mv88e6xxx
Marvell mv88e6xxx switch series cannot perform MAC learning from
CPU-injected (FROM_CPU) DSA frames, which results in 2 issues.
- excessive flooding, due to the fact that DSA treats those addresses
as unknown
- the risk of stale routes, which can lead to temporary packet loss

Backport those patch series from netdev mailing list, which solve these
issues by adding and clearing static entries to the switch's FDB.

Add a hack patch to set default VID to 1 in port_fdb_{add,del}. Otherwise
the static entries will be added to the switch's private FDB if VLAN
filtering disabled, which will not work.

The switch may generate an "ATU violation" warning when a client moves
from the CPU port to a switch port because the static ATU entry added by
DSA core still points to the CPU port. DSA core will then clear the static
entry so it is not fatal. Disable the warning so it will not confuse users.
