From a6b0d0806055a53a2538df83f8322c38ee9f3441 Mon Sep 17 00:00:00 2001 From: Mikhail Zhilkin Date: Sat, 9 Jul 2022 17:09:57 +0000 Subject: [PATCH] =?utf8?q?ramips:=20get=20MAC=20addr=20from=20the=20encryp?= =?utf8?q?ted=20partition=20(WG4=D1=85=D1=85223)?= MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This commit resolves #10062. Adds decryption of the Arcadyan WG4xx223 configuration partition (board_data)to get base MAC address from it. As a result, after this change the hack with saving MAC addressees to u-boot-env before installation of OpenWrt is no longer necessary. This is necessary for the following devices: - Beeline Smartbox Flash (Arcadyan WG443223) - MTS WG430223 (Arcadyan WG430223) Example: +----------------+-------------------+------------------------+ | | MTS WG430223 | Beeline Smartbox Flash | +----------------+-------------------+------------------------+ | base mac (mtd) | A4:xx:xx:51:xx:F4 | 30:xx:xx:51:xx:06 | | label | A4:xx:xx:51:xx:F4 | 30:xx:xx:51:xx:09 | | LAN | A4:xx:xx:51:xx:F6 | 30:xx:xx:51:xx:09 | | WAN | A4:xx:xx:51:xx:F4 | 30:xx:xx:51:xx:06 | | WLAN_2g | A4:xx:xx:51:xx:F5 | 30:xx:xx:51:xx:07 | | WLAN_5g | A6:xx:xx:21:xx:F5 | 32:xx:xx:41:xx:07 | +----------------+-------------------+------------------------+ Collected statistic shows that the 2-4th bits of the 7th byte of the WLAN_5g MAC are the constant (see #10062 for more details): - Beeline Smartbox Flash - 100 - MTS WG430223 - 010 Signed-off-by: Mikhail Zhilkin --- target/linux/ramips/image/mt7621.mk | 4 ++-- .../mt7621/base-files/etc/board.d/02_network | 14 ++++++++----- .../etc/hotplug.d/ieee80211/10_fix_wifi_mac | 21 +++++++++++++------ 3 files changed, 26 insertions(+), 13 deletions(-) diff --git a/target/linux/ramips/image/mt7621.mk b/target/linux/ramips/image/mt7621.mk index 96ae2765b9..c3a63fa934 100644 --- a/target/linux/ramips/image/mt7621.mk +++ b/target/linux/ramips/image/mt7621.mk @@ -311,7 +311,7 @@ define Device/beeline_smartbox-flash IMAGE/factory.trx := append-kernel | append-ubi | check-size IMAGE/sysupgrade.bin := sysupgrade-tar | append-metadata DEVICE_PACKAGES := kmod-usb3 kmod-mt7615e kmod-mt7615-firmware \ - uboot-envtools + uboot-envtools uencrypt endef TARGET_DEVICES += beeline_smartbox-flash @@ -1327,7 +1327,7 @@ define Device/mts_wg430223 IMAGES += factory.trx IMAGE/factory.trx := append-kernel | append-ubi | check-size IMAGE/sysupgrade.bin := sysupgrade-tar | append-metadata - DEVICE_PACKAGES := kmod-mt7615e kmod-mt7615-firmware uboot-envtools + DEVICE_PACKAGES := kmod-mt7615e kmod-mt7615-firmware uboot-envtools uencrypt endef TARGET_DEVICES += mts_wg430223 diff --git a/target/linux/ramips/mt7621/base-files/etc/board.d/02_network b/target/linux/ramips/mt7621/base-files/etc/board.d/02_network index 7211422364..af493789ba 100644 --- a/target/linux/ramips/mt7621/base-files/etc/board.d/02_network +++ b/target/linux/ramips/mt7621/base-files/etc/board.d/02_network @@ -138,11 +138,10 @@ ramips_setup_macs() wan_mac=$(mtd_get_mac_ascii u-boot-env et1macaddr) label_mac=$(mtd_get_mac_binary factory 0x4) ;;
