* tplink-safeloader: add support for TP-Link CPE510 v3.20Gioacchino Mazzurco2020-12-141-1/+4
| | | | | | | | | | | | | This adds new strings for the v3.20 to the support list of the already supported TP-Link CPE510 v3. The underlying hardware appears to be the same, similar to the situation with CPE210 v3.20 in 4a2380a1e778 ("tplink-safeloader: expand support list for TP-Link CPE210 v3") Signed-off-by: Gioacchino Mazzurco <gio@altermundi.net> [extended commit message] Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* firmware-utils: tplink-safeloader: refactor meta-partition paddingSander Vanheule2020-12-072-68/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because some padding values in the TP-Link safeloader image generation were hardcoded, different values were sometimes used throughout a factory image. TP-Link's upgrade images use the same value everywhere, so let's do the same here. Although a lot of TP-Link's safeloader images have padded partition payloads, images for the EAP-series of AC devices don't. This padding is therefore also made optional. By replacing the type of the padding value byte with a wider datatype, new values outside of the previously valid range become available. Use these new values to denote that padding should not be performed. Because char might be signed, also replace the char literals by a numeric literal. Otherwise '\xff' might be sign extended to 0xffff. This results in factory images differing by 1 byte for: * C2600 * ARCHER-C5-V2 * ARCHERC9 * TLWA850REV2 * TLWA855REV1 * TL-WPA8630P-V2-EU * TL-WPA8630P-V2-INT * TL-WPA8630P-V2.1-EU * TLWR1043NDV4 * TL-WR902AC-V1 * TLWR942NV1 * RE200-V2 * RE200-V3 * RE220-V2 * RE305-V1 * RE350-V1 * RE350K-V1 * RE355 * RE450 * RE450-V2 * RE450-V3 * RE500-V1 * RE650-V1 The following factory images no longer have padding, shrinking the factory images by a few bytes for: * EAP225-OUTDOOR-V1 * EAP225-V3 * EAP225-WALL-V2 * EAP245-V1 * EAP245-V3 Signed-off-by: Sander Vanheule <sander@svanheule.net>
* firmware-utils: tplink-safeloader: refactor meta-partition generationSander Vanheule2020-12-072-84/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | TP-Link safeloader firmware images contain a number of (small) partitions with information about the device. These consist of: * The data length as a 32-bit integer * A 32-bit zero padding * The partition data, with its length set in the first field The OpenWrt factory image partitions that follow this structure are soft-version, support-list, and extra-para. Refactor the code to put all common logic into one allocation call, and let the rest of the data be filled in by the original functions. Due to the extra-para changes, this patch results in factory images that change by 2 bytes (not counting the checksum) for three devices: * ARCHER-A7-V5 * ARCHER-C7-V4 * ARCHER-C7-V5 These were the devices where the extra-para blob didn't match the common format. The hardcoded data also didn't correspond to TP-Link's (recent) upgrade images, which actually matches the meta-partition format. A padding byte is also added to the extra-para partition for EAP245-V3. Signed-off-by: Sander Vanheule <sander@svanheule.net>

It's based on MediaTek MT7628AN+MT7610EN like the v2/v3. Specifications -------------- - MediaTek MT7628AN (580 Mhz) - 64 MB of RAM - 8 MB of FLASH - 2T2R 2.4 GHz and 1T1R 5 GHz - 1x 10/100 Mbps Ethernet - 8x LED (GPIO-controlled), 2x button - UART connection holes on PCB (57600 8n1) There are 2.4G and 5G LEDs in red and green which are controlled separately. MAC addresses ------------- The MAC address assignment matches stock firmware, i.e.: LAN : *:8E 2.4G: *:8D 5G : *:8C MAC address assignment has been done according to the RE200 v2. The label MAC address matches the OpenWrt ethernet address. Installation ------------ Web Interface ------------- It is possible to upgrade to OpenWrt via the web interface. Simply flash the -factory.bin from OEM. In contrast to a stock firmware, this will not overwrite U-Boot. Recovery -------- Unfortunately, this devices does not offer a recovery mode or a tftp installation method. If the web interface upgrade fails, you have to open your device and attach serial console. Instructions for serial console and recovery may be checked out in commit 6d6f36ae787c ("ramips: add support for TP-Link RE200 v2") or on the device's Wiki page.

* firmware-utils/tplink-safeloader: add compat levelSander Vanheule2020-09-091-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TP-Link has introduced a compatibility level to prevent certain downgrades. This information is stored in the soft-version partition, changing the data length from 0xc to 0x10. The compatibility level doesn't change frequently. For example, it has the following values for the EAP245v3 (released 2018-Q4): * FW v2.2.0 (2019-05-30): compat_level=0 * FW v2.3.0 (2019-07-31): compat_level=0 * FW v2.3.1 (2019-10-29): compat_level=1 * FW v2.20.0 (2020-04-23): compat_level=1 Empty flash values (0xffffffff) are interpreted as compat_level=0. If a firmware upgrade file has a soft-version block without compatibility level (data length < 0x10), this is also interpreted as compat_level=0. By including a high enough compatibility level in factory images, stock firmware can be convinced to accept the image. A compatibility level aware firmware will keep the original value.

Therefore, it seems to be the safest option to set the OpenWrt compatibility level to the highest known value instead of the highest possible value (0xfffffffe), to ensure users do not get unexpectedly refused firmware upgrades when using a device reverted back to stock. To remain compatible with existing devices and not produce different images, the image builder doesn't store a compatibility level if it is zero. Signed-off-by: Sander Vanheule <sander@svanheule.net>

Specifications -------------- - QCA9563 750MHz, 2.4GHz WiFi - QCA9888 5GHz WiFi - 8MiB SPI Flash - 128MiB RAM - 3 GBit Ports (QCA8337) - PLC (QCA7550) MAC address assignment ---------------------- WiFi 2.4GHz and LAN share the same MAC address as printed on the label. 5GHz WiFi uses LAN-1, based on assumptions from similar devices. LAN Port assignment ------------------- While there are 3 physical LAN ports on the device, there will be 4 visible ports in OpenWrt. The fourth port (internal port 5) is used by the PowerLine Communication SoC and thus treated like a regular LAN port. Versions -------- Note that both TL-WPA8630 and TL-WPA8630P, as well as the different country-versions, differ in partitioning, and therefore shouldn't be cross-flashed. This adds support for the two known partitioning variants of the TL-WPA8630P, where the variants can be safely distinguished via the tplink-safeloader SupportList. For the non-P variants (TL-WPA8630), at least two additional partitioning schemes exist, and the same SupportList entry can have different partitioning. Thus, we don't support those officially (yet). Also note that the P version for Germany (DE) requires the international image version, but is properly protected by SupportList. In any case, please check the OpenWrt Wiki pages for the device before flashing anything! Installation ------------ Installation is possible from the OEM web interface. Make sure to install the latest OEM firmware first, so that the PLC firmware is at the latest version. However, please also check the Wiki page for hints according to altered partitioning between OEM firmware revisions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TP-Link RE200 v3 is a wireless range extender with Ethernet and 2.4G and 5G WiFi with internal antennas. It's based on MediaTek MT7628AN+MT7610EN like the v2. Specifications -------------- - MediaTek MT7628AN (580 Mhz) - 64 MB of RAM - 8 MB of FLASH - 2T2R 2.4 GHz and 1T1R 5 GHz - 1x 10/100 Mbps Ethernet - 8x LED (GPIO-controlled), 2x button Unverified: - UART header on PCB (57600 8n1) There are 2.4G and 5G LEDs in red and green which are controlled separately. MAC addresses ------------- MAC address assignment has been done according to the RE200 v2. The label MAC address matches the OpenWrt ethernet address. Installation ------------ Web Interface ------------- It is possible to upgrade to OpenWrt via the web interface. Simply flash the -factory.bin from OEM. In contrast to a stock firmware, this will not overwrite U-Boot. Recovery -------- Unfortunately, this devices does not offer a recovery mode or a tftp installation method. If the web interface upgrade fails, you have to open your device and attach serial console. The device has not been opened for adding support. However, it is expected that the behavior is similar to the RE200 v2. Instructions for serial console and recovery may be checked out in commit 6d6f36ae787c ("ramips: add support for TP-Link RE200 v2") or on the device's Wiki page.

* ramips: fix/tidy up 4M tplink-v2-image flash layoutsAdrian Schmutzler2020-08-031-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | For the TP-Link 4M devices with tplink-v2-image recipe (mktplinkfw2.c), there are two different flash layouts based on the size of the (u)boot partition: device uboot OEM firmware OpenWrt (incl. config) tl-wr840n-v5 0x20000 0x3c0000 0x3d0000 tl-wr841n-v14 0x10000 0x3d0000 0x3e0000 In both cases, the 0x10000 config partition is used for the firmware partition as well due to the limited space available and since it's recreated by the OEM firmware anyway. However, the TFTP flashing process will only copy data up to the size of the initial (OEM) firmware size. Therefore, while we can use the bigger partition to have additional erase blocks on the device, we have to limit the image sizes to the TFTP limits. So far, only one layout definition has been set up in mktplinkfw2.c for 4M mediatek devices. This adds a second one and assigns them to the devices so the image sizes are correctly restrained.

It seems to be identical to the v2 revision, except that it lacks a WPS LED and has different GPIO for amber WAN LED. Specification: - 775/650/258 MHz (CPU/DDR/AHB) - 64 MB of RAM (DDR2) - 8 MB of FLASH (SPI NOR) - 3T3R 2.4 GHz - 2T2R 5 GHz - 5x 10/100 Mbps Ethernet - 6x LED, 2x button - UART header on PCB Flash instruction (WebUI): Download *-factory.bin image and upload it via the firmwary upgrade function of the stock firmware WebUI. Flash instruction (TFTP): 1. Set PC to fixed IP address 192.168.0.66 2. Download *-factory.bin image and rename it to tp_recovery.bin 3. Start a tftp server with the file tp_recovery.bin in its root directory 4. Turn off the router 5. Press and hold reset button 6. Turn on router with the reset button pressed and wait ~15 seconds 7. Release the reset button and after a short time the firmware should be transferred from the tftp server 8. Wait ~30 second to complete recovery While TFTP works for OpenWrt images, my device didn't accept the only available official firmware "Archer C60(EU)_V3.0_190115.bin". In contrast to earlier revisions (v2), the v3 contains the (same) MAC address twice, once in 0x1fa08 and again in 0x1fb08. While the partition-table on the device refers to the latter, the firmware image contains a different partition-table for that region: name device firmware factory-boot 0x00000-0x1fb00 0x00000-0x1fa00 default-mac 0x1fb00-0x1fd00 0x1fa00-0x1fc00 pin 0x1fd00-0x1fe00 0x1fc00-0x1fd00 product-info 0x1fe00-0x1ff00 0x1fd00-0x1ff00 device-id 0x1ff00-0x20000 0x1ff00-0x20000 While the MAC address is present twice, other data like the PIN isn't, so with the partitioning from the firmware image the PIN on the device would actually be outside of its partition.

The 5G LED is currently not supported, since the GPIOs couldn't be determined. Installation ------------ Web Interface ------------- It is possible to upgrade to OpenWrt via the web interface. However, the OEM firmware upgrade file is required and a tool to fix the MD5 sum of the header. This procedure overwrites U-Boot and there is not failsafe / recovery mode present! To prepare an image, you need to take the header and U-Boot (i.e. 0x200 + 0x20000 bytes) from an OEM firmware file and attach the factory image to it. Then fix the header MD5Sum1. Serial console -------------- Opening the case is quite hard, since it is welded together. Rename the OpenWrt factory image to "test.bin", then plug in the device and quickly press "2" to enter flash mode (no line feed). Follow the prompts until OpenWrt is installed. Unfortunately, this devices does not offer a recovery mode or a tftp installation method. If the web interface upgrade fails, you have to open your device and attach serial console. Since the web upgrade overwrites the boot loader, you might also brick your device. Additional notes ---------------- MAC address assignment is based on stock-firmware. For me, the device assigns the MAC on the label to Ethernet and the 2.4G WiFi, while the 5G WiFi has a separate MAC with +2. *:88 Ethernet/2.4G label, uboot 0x1fc00, userconfig 0x0158 *:89 unused userconfig 0x0160 *:8A 5G not present in flash This seems to be the first ramips device with a TP-Link v1 header. The original firmware has the string "EU" embedded, there might be some region- checking going on during the firmware upgrade process. The original firmware also contains U-Boot and thus overwrites the boot loader during upgrade. In order to flash back to stock, the first header and U-Boot need to be stripped from the original firmware. Signed-off-by: Andreas Böhler <dev@aboehler.at>

Note that the firmware can't be uploaded without prior special preparation. For the most recent instructions on how to do that, visit the OpenWRT wiki page of the Ubiquiti airCube ISP for details: https://openwrt.org/toh/ubiquiti/ubiquiti_aircube_isp Current procedure: With the original firmware 2.5.0 it is possible to upload and execute a script via the configuration. To do that download and unpack the original configuration, adapt uhttpd config to execute another lua handler (placed in the config directory) and pack and upload it again. The lua handler can call a script that mounts an overlayfs and modifies the "fwupdate.real" binary so that an unsigned image is accepted. The overlayfs is necessary because a security system (called tomoyo) doesn't allow binaries in other locations than /sbin/fwupdate.real (and maybe some more) to access the flash when executed via network. A big thanks to Torvald Menningen (Snap) from the OpenWRT forum for finding out how to patch the binary so that it accepts an unsigned image. The current step-by-step procedure is: - Use a version 2.5.0 of the original firmware. This is important because a binary file will be modified. - Download a configuration. - Unpack it (it's just a tar gz file without an ending). - Add the following to uhttpd: `````` config 'uhttpd' 'other' list listen_http 0.0.0.0:8080 list listen_http [::]:8080 option 'home' '/tmp/persistent/config/patch/www' option lua_prefix '/lua' option lua_handler '/tmp/persistent/config/patch/handler.lua' `````` - Create a `patch` subfolder. - Create a `patch/www` subfolder. - Create a `patch/handler.lua` with the following content: `````` function handle_request(env) uhttpd.send("Status: 200 OK\r\n") uhttpd.send("Content-Type: text/plain\r\n\r\n") local command = "/bin/sh /tmp/persistent/config/patch/patch.sh 2>&1" local proc = assert(io.popen(command)) for line in proc:lines() do uhttpd.send(line.."\r\n") end proc:close() end `````` - Create a `patch/patch.sh` with the following content: `````` #!/bin/sh -x set -e set -u set -x UBNTBOX_PATCHED="/tmp/fwupdate.real" MD5FILE="/tmp/patchmd5" cat <<EOF > ${MD5FILE} c33235322da5baca5a7b237c09bc8df1 /sbin/fwupdate.real EOF # check md5 of files that will be patched if ! md5sum -c ${MD5FILE} then echo "******** Error when checking files. Refuse to do anything. ********" exit 0 fi # prepare some overlay functionality LOWERDIR="/tmp/lower_root" mkdir -p ${LOWERDIR} mount -t squashfs -oro /dev/mtdblock3 ${LOWERDIR} overlay_some_path() { PATH_TO_OVERLAY=$1 ALIAS=$2 UPPERDIR="/tmp/over_${ALIAS}" WORKDIR="/tmp/over_${ALIAS}_work" mkdir -p ${UPPERDIR} mkdir -p ${WORKDIR} mount -t overlay -o lowerdir=${LOWERDIR}${PATH_TO_OVERLAY},upperdir=${UPPERDIR},workdir=${WORKDIR} overlay ${PATH_TO_OVERLAY} } # patch the ubntbox binary. overlay_some_path "/sbin" "sbin" echo -en '\x10' | dd of=/sbin/fwupdate.real conv=notrunc bs=1 count=1 seek=24598 echo "******** Done ********" `````` - Repack the configuration. - Upload it via the normal web interface. - Wait about a minute. The webserver should restart. - Now there is a second web server at port 8080 which can call the lua script. Visit the page with a web browser. Link is for example http://192.168.1.1:8080/lua - You should see the output of the script with a "*** Done ***" at the end. Note that the patches are not permanent. If you restart the router you have to re-visit the link (but not re-upload the config). - Now you can upload an unsigned binary via the normal web interface.
