Development scripts and notes for Btrfs fscrypt

This repository contains some simple scripts that I've used for developing fscrypt for Btrfs.

Setup

• Build the fscryptctl Btrfs fork.
• Create a config.sh file which defines:
  • PATH to include the fscryptctl build.
  • DEV as the block device to test on (which will be reformatted).
  • MNT as the mountpoint for the filesystem to test on.

For example:

export PATH="/home/vmuser/repos/fscryptctl:$PATH"
DEV=/dev/vdb
MNT=/mnt

Scripts

• recreate.sh: Create a Btrfs filesystem with fscrypt enabled.
• mount.sh: Mount the previously created filesystem and unlock the encrypted directory.
• lock.sh: Lock the encrypted directory.
• unlock.sh: Unlock the encrypted directory.
• smoke_test.sh: Run basic tests on Btrfs with fscrypt.
• key.py: Output the key used by the encrypted directory.
