Decrypt LUKS volumes with a TPM on Fedora Linux

Decrypt LUKS volumes with a TPM on Fedora Linux

This guide allows you to use the TPM on your computer to decrypt your LUKS encrypted volumes. If you are worried about a cold boot attack on your hardware please DO NOT use this guide with your root volume!

Preflight Checks

Verify that you have a TPM in your computer:

# systemd-cryptenroll --tpm2-device=list
PATH DEVICE DRIVER

set -e, -u, -o, -x pipefail explanation

set -e, -u, -o, -x pipefail

The set lines

  • These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
  • With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.
  • set -euxo pipefail is short for:
set -e
set -u

Keychron keyboards on Linux + Bluetooth fixes

Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work (NOT FOR QMK-BASED BOARDS)

Older Keychron keyboards (those not based on QMK) use the hid_apple driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.

GSOC 2020: Writing a FLIF Decoder and Encoder for FFmpeg

GSOC 2020: Writing a FLIF Decoder and Encoder for FFmpeg

[Free Lossless Image Format][1], or FLIF is the precursor to [JPEG XL][2] and [FUIF][3]. It claims to have a higher level of compression or lower file size than conventional lossless image formats like PNG, Lossless JPEG 2000, etc. FLIF and FUIF development has been stopped in favour of JPEG XL.

[The task was to write an encoder and decoder for this format for FFmpeg.][4]

Problems & Solutions for Interaction Between C and Go

At Vimeo, on the transcoding team, we work a lot with Go, and a lot with C, for various tasks such as media ingest. This means we use CGO quite extensively, and consequently, have run into bits that are perhaps not very well documented, if at all. Below is my effort to document some of the problems we've run into, and how we fixed or worked around them.

Many of these are obviously wrong in retrospect, but hindsight is 20/20, and these problems do exist in many codebases currently.

Some are definitely ugly, and I much welcome better solutions! Tweet me at @daemon404 if you have any, or have your own CGO story/tips, please! I'd love to learn of them.
