From b11ad48764404d6eefc01b5acf9e54c9f6f00973 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Fri, 17 Jul 2020 12:06:03 +0200 Subject: [PATCH] ath79: support for TP-Link EAP245 v1 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit TP-Link EAP245 v1 is an AC1750 (802.11ac Wave-1) ceiling mount access point. Device specifications: * SoC: QCA9563 @ 775MHz * RAM: 128MiB DDR2 * Flash: 16MiB SPI-NOR * Wireless 2.4GHz (SoC): b/g/n, 3x3 * Wireless 5Ghz (QCA9880): a/n/ac, 3x3 * Ethernet (AR8033): 1× 1GbE, 802.3at PoE Flashing instructions: * Upgrade the device to firmware v1.4.0 if necessary * Exploit the user management page in the web interface to start telnetd by changing the username to `;/usr/sbin/telnetd -l/bin/sh&`. * Immediately change the malformed username back to something valid (e.g. 'admin') to make ssh work again. * Use the root shell via telnet to make /tmp world writeable (chmod 777) * Extract /usr/bin/uclited from the device via ssh and apply the binary patch listed below. The patch is required to prevent `uclited -u` in the last step from crashing. * Copy the patched uclited programme back to the device at /tmp/uclited (via ssh) * Upload the factory image to /tmp/upgrade.bin (via ssh) * Run `chmod +x /tmp/uclited && /tmp/uclited -u` to install OpenWrt. --- xxd uclited +++ xxd uclited-patched @@ -53796,7 +53796,7 @@ 000d2240: 8c44 0000 0320 f809 0000 0000 8fbc 0010 .D... .......... 000d2250: 8fa6 0a4c 02c0 2821 8f82 87b8 0000 0000 ...L..(!........ -000d2260: 8c44 0000 0c13 45e0 27a7 0018 8fbc 0010 .D....E.'....... +000d2260: 8c44 0000 2402 0000 0000 0000 8fbc 0010 .D..$........... 000d2270: 1040 001d 0000 1821 8f99 8374 3c04 0058 .@.....!...t<..X 000d2280: 3c05 0056 2484 a898 24a5 9a30 0320 f809 <..V$...$..0. ..

The binary patch might not apply to uclited from other firmware versions. EAP245 v1 device support was originally developed and maintained by Julien Dusser out-of-tree. This patch and "ath79: prepare for 1-port TP-Link EAP2x5 devices" are based on that work.
