This is a dual-radio 802.11a/b/g/n/ac access point with
dual Gigabit Ethernet.
There are two closely related models: The AP-324, which has external
antenna connectors, and the AP-325, which has internal antennas.
The board appears to be identical, and the same image works on both.
Additionally, the Siemens Scalance W1750D is an OEM variant using
the same board, so the image also works on that.
Unfortunately the factory APBoot bootloader enforces cryptographic
signatures on the firmware before booting, so a modified version
must be flashed via the serial port. See [^1] for details.

How to install
==============
The stock bootloader APBoot appears to be vendor fork of U-Boot, which
disables much of the usual functionality and comes with its own booting
and firmware upgrade logic.
Unfortunately, this logic enforces RSA signatures on images,
even for the default boot from NAND.
Therefore, a patched bootloader is needed, which is built as a package.
In addition to the signature check removal, this also changes
the serial baudrate to 115200.
Luckily, the stock firmware does not disable the `sf` command
(it just hides it until you run `diag`), so the patched bootloader
can be fetched via TFTP and then flashed via console.
Flashing patched APBoot
-----------------------
* Build OpenWrt, or download `openwrt-ipq806x-generic-aruba_ap-32x-apboot.mbn`
* Connect serial cable and wired ethernet
* Access stock APBoot console at Baud 9600
* Flash patched bootloader:
```
setenv serverip <your TFTP server IP>
setenv autostart n
netget 44000000 openwrt-ipq806x-generic-aruba_ap-32x-apboot.mbn
sf probe 0
sf erase 220000 100000
sf write 44000000 220000 100000
reset
```
Booting OpenWrt
---------------
* Connect serial cable and wired ethernet
* Access patched APBoot console at Baud 115200
* Run `setenv serverip <your TFTP server IP>`
* Run `tftpboot openwrt-ipq806x-generic-aruba_ap-32x-initramfs.ari`
Installing OpenWrt
------------------
* Connect serial cable and wired ethernet
* Access patched APBoot console at Baud 115200
* Consider backing up stock firmware(s) (UBI volumes `aos0` and/or `aos1`)
by booting into OpenWrt via initramfs (see above) and dumping them
* Wipe and repartition NAND flash (see below for explanation):
```
nand device 0
nand erase.chip
reset
ubi part ubifs
ubi remove ubifs
ubi create ubifs 1
ubi create rootfs_data
```
* Follow steps above to boot OpenWrt via initramfs
* From OpenWrt, persist installation via sysupgrade
Reverting to stock FW
---------------------
The patched bootloader remains compatible with the original firmware,
so you can just wipe the NAND, let APBoot recreate the partitions,
and flash back the `aos0`/`aos1` backup from above.
Current status
==============
Tested and working
------------------
* Console
* Wired GbE (both ports)
* WiFi (both 2.4G and 5G)
* LEDs
* Restart Button
* USB port
* External watchdog
* TPM
* BLE SoC
Future work
-----------
* GPIOs for:
* power source (8 indicates DC jack, 59 indicates 802.3at)
* reset source (64 for warm reset, 65 for watchdog)
* USB overcurrent (63)
* BLE SoC reflashing
* CC2540 comes with Aruba-specific FW out of the box
* Debug header is exposed on PCB (pinout GND-VCC-Clock-Data-Reset),
but that requires disassembly
* Stock BLE FW appears to support reflashing via UART, but protocol
would need to be reverse-engineered
* ramoops/pstore
* It appears that APBoot clears the RAM on boot, might be something
we can patch out as well
* Porting a modern U-Boot

Factory NAND flash
------------------
* 32MiB MTD partition `aos0`, formatted as UBI
* 32MiB UBI volume `aos0`
* contains kernel+initrd of the primary firmware,
initrd contains the entire root FS
* 32MiB MTD partition `aos1`, formatted as UBI
* 32MiB UBI volume `aos1`
* contains kernel+initrd of the secondary firmware,
initrd contains the entire root FS
* 64MiB MTD partition `ubifs`, formatted as UBI
* 64MiB UBI volume `ubifs`
* Contains UBIFS, overlay-mounted on top of the initrd,
shared between firmware slots
APBoot understands UBI, and will read the kernel from the
`aos0` or `aos1` volume (depending on `os_partition`)
with fallback to the other one in case a check fails.
Kernels are expected to have a vendor-specific header, the included
script will add that header with the correct checksum but no signature.
OpenWrt NAND flash
------------------
OpenWrt assumes separate UBI volumes for kernel and rootfs,
as well as a volume that must be named `rootfs_data` for the UBIFS.
Unfortunately, APBoot actively checks the UBI volumes at boot, and will
repartition if it doesn't find the volumes that it expects (listed above).
Luckily, it doesn't check their size, only their existence. Therefore,
we can use the following layout:
* 32MiB MTD partition `aos0`, formatted as UBI
* 32MiB UBI volume `aos0`
* contains OpenWrt kernel+initrd
* 32MiB MTD partition `aos1`, formatted as UBI
* 32MiB UBI volume `aos1`
* contains OpenWrt root squashfs
* 64MiB MTD partition `ubifs`, formatted as UBI
* small (single-LEB) UBI volume `ubifs`
* Dummy volume, only there to satisfy APBoot
* almost 64MiB UBI volume `rootfs_data`
* contains UBIFS, overlay-mounted on top of the rootfs

Unfortunately, this does not work on the Aruba AP-325 (and variants), since

Add basic support for the TP-Link SG2008P V3 variant. The switch appears
to be identical to the V1 variant, except that it uses the MP3924
instead of the TPS23861 PoE chip.
Specifications:
---------------
* SoC: Realtek RTL8380M
* Flash: 32 MiB SPI flash (Vendor varies)
* RAM: 256 MiB (Vendor varies)
* Ethernet: 8x 10/100/1000 Mbps with PoE on 4 ports
* Buttons: 1x "Reset" button on front panel
* Power: 53.5V DC barrel jack
* UART: 1x serial header, unpopulated
* PoE: 1x MPS MP3924 I2C PoE controller
Works:
------
- (8) RJ-45 ethernet ports
- Switch functions
- System LED
- Basic PoE support (no driver, but a startup script puts the chip
into AUTO mode)
Not yet enabled:
----------------
- PoE, Link/Act, PoE max and System LEDs
Install via web interface:
-------------------------
Not supported at this time.
Install via serial console/tftp:
--------------------------------
The footprints R27 (0201) and R28 (0402) are not populated. To enable
serial console, 50 ohm resistors should be soldered -- any value from
0 ohm to 50 ohm will work. R27 can be replaced by a solder bridge.
The u-boot firmware drops to a TP-Link specific "BOOTUTIL" shell at
38400 baud. There is no known way to exit out of this shell, and no
way to do anything useful.
Ideally, one would trick the bootloader into flashing the sysupgrade
image first. However, if the image exceeds 6MiB in size, it will not
work. The sysupgrade image can also be flashed. To install OpenWRT:
Prepare a tftp server with:
1. server address: 192.168.0.146
2. the image as: "uImage.img"
Power on device, and stop boot by pressing any key.
Once the shell is active:
1. Ground out the CLK (pin 16) of the ROM (U7)
2. Select option "3. Start"
3. Bootloader notes that "The kernel has been damaged!"
4. Release CLK as sson as bootloader thinks image is corrupted.
5. Bootloader enters automatic recovery -- details printed on console
6. Watch as the bootloader flashes and boots OpenWRT.
Blind install via tftp:

This method works when it's not feasible to install a serial header.

1. server address: 192.168.0.146
2. the image as: "uImage.img"
3. Watch network traffic (tcpdump or wireshark works)
4. Power on the device.
5. Wait 1-2 seconds then ground out the CLK (pin 16) of the ROM (U7)
6. When 192.168.0.30 makes tftp requests, release pin 16
7. Wait 2-3 minutes for device to auto-flash and boot OpenWRT

handle_send_a() computed the SRP "A" parameter length as
len = ntohl(msg->len) - sizeof(struct ead_msg_number);
sizeof(struct ead_msg_number) is 1, and the subtraction is evaluated in
unsigned arithmetic. A packet with msg->len == 0 therefore wraps the
result to a huge value which, assigned to the signed int len, becomes -1.
The following bounds check is signed:
if (len > MAXPARAMLEN + 1)
return false;
so -1 passes, and memcpy(A.data, number->data, len) runs with len cast to
size_t (~SIZE_MAX) against the 257-byte abuf, crashing the daemon.
Neither parse_message() nor handle_packet() validate msg->len (only the
captured packet length), so an unauthenticated attacker on the local
segment can reach this path and crash ead with a single crafted packet.
Validate the claimed length in unsigned arithmetic before the subtraction
and bound it on both sides. Doing the upper-bound check unsigned as well
also closes a 32-bit-only variant where sizeof(ead_packet) + msg->len
overflows in handle_packet(), letting a large msg->len reach the same
negative-len path.

When growing the segment array in find_entry(), the memset() that zeroes
the newly allocated slots computed the destination with redundant sizeof
scaling:
memset(segments + (num_segments * sizeof(struct tffs_entry_segment)), ...)
segments is a typed pointer, so pointer arithmetic already scales by the
element size. Multiplying the offset by sizeof again advances the
destination by num_segments * sizeof^2 bytes, landing far outside the
realloc()'d buffer and zeroing unrelated heap memory whenever a TFFS
entry spans multiple segments that require array expansion.
Drop the redundant multiplication so the memset targets segments[num_segments].
This is a robustness fix for malformed/corrupt TFFS content; the parser
only reads the on-device nand-tffs MTD partition as root, so it is not
considered security relevant.

Backport two upstream commits that replace memset() on coherent DMA
descriptor rings with explicit WRITE_ONCE() status word stores.
On 32-bit PowerPC platforms like apm821xx, coherent DMA memory may be
mapped uncached. The optimized memset() path can use dcbz there, which
triggers alignment warnings and spams the kernel log.
