How I use Hassio as a Bluetooth: Keyboard\MediaControl\Mouse Combo

OVERVIEW:

Hello, 😀

PART 1:

I've been using Hassio for over a year now and am generally happy with it. I use it to control fireplaces, shades, lights, etc., but mainly use it to control my entertainment systems.

I'm a cord cutter and watch all my video with an Amazon FireTV 3rd gen stick and my audio with a Sonos surround sound bar.

Description

For some reason IDA executes FreeLibrary() to the plugin immediately after getting its PLUGIN structure's address, so later invocations of the plugin lead to calls to nowhere (that was supposed to be python3.dll). Simply patching the location of the FreeLibrary() call fixes the issue. The location is easy to find: go by cross-references to a place where the call to FreeLibrary is followed by a reference to the string "%s: incompatible plugin version..." and NOP it away.

This is just a dump of some interesting undocumented features of webOS (3.8 specifically, on early 2018 4k LG TV) and other development-related tips.

Mappings for DMI/SMBIOS to Linux and dmidecode

Information can be put into dmi tables via some qemu-system hosts (x86_64 and aarch64). That information is exposed in Linux under /sys/class/dmi/id and can be read with dmidecode. The names are very annoyingly inconsistent. The point of this doc is to map them.

Mappings

Example qemu cmdline:

qemu-system-x86_64 -smbios type=<type>,field=value[,...]

qemu-system-x86_64 -smbios type=0,vendor=superco,version=1.2.3
