Optional: Use Keyfile in Initramfs to unlock encrypted root

+

Using a key file to unlock /boot/

- Using the above installation method, you will have to unlock the encrypted file system twice - (once in GRUB, and again when booting Parabola). - To circumvent this, you can insert a keyfile into the initramfs. This is generally safe, because the /boot/ directory is encrypted.
- First create a keyfile:
+ By default, you will have to enter your LUKS passphrase twice; once in GRUB, and once when booting the kernel. + GRUB unlocks the encrypted partition and then loads the kernel, but the kernel is not aware of the fact + that it is being loaded from an encrypted volume. Therefore, you will be asked to enter your passphrase a second time. + A workaround is to put a keyfile inside initramfs, with instructions for the kernel to use it when + booting. This is safe, because /boot/ is encrypted (otherwise, putting a keyfile inside initramfs would be a bad idea).
+ + Generate the file:
# dd bs=512 count=4 if=/dev/urandom of=/etc/mykeyfile iflag=fullblock
- Add the keyfile to the Luks Device:
+ Insert it into the luks volume:
# cryptsetup luksAddKey /dev/sdX /etc/mykeyfile
Add the keyfile to the initramfs by adding it to FILES in /etc/mkinitcpio.conf. For example:
+ Integrate it inside initramfs:
# FILES="/etc/mykeyfile"
- Re-create the initramfs image:
+ Create the initramfs image from scratch:
# mkinitcpio -p linux-libre
- Reboot and add the following to the kernel command line in GRUB:
+ Add the following to your grub.cfg, or add it in the kernel command line for GRUB:
# cryptkey=rootfs:/etc/mykeyfile

- If everything works as expected, permanently add the kernel parameter to the GRUB config using - the instructions at grub_cbfs.html. + You can also place this inside the grub.cfg that exists in CBFS: grub_cbfs.html.

Which ROM image should I use?

+

Acquiring the correct ROM image

You can either work directly with one of the ROM images already included in the libreboot ROM archives, or re-use the ROM that you have currently flashed. For the purpose of this tutorial it is assumed that your ROM image file is named libreboot.rom, so please make sure to adapt.

- -
-

Use one of the provided ROM images

-

- Libreboot ROM images are distributed in separate tar archives, named {computer_model}.tar.xz. - If you build from source without generated any release archives, - the ROM images will be in ./bin/{computer_model}/. Make a working copy of the ROM you want to use: -
- $ cp ./bin/{computer_model}/{computer_model}_{keyboard_layout}_{mode}.rom libreboot.rom -
- {keyboard_layout} defines the keyboard layout that will be available on the GRUB console. This might be important - if you protect GRUB with a password later on and want to insert non-ASCII characters. - {mode} can be vesafb or txtmode and starts GRUB with a background image or in text mode. -

-
- -
-

Re-use the currently flashed ROM image

-

- If you want to re-use the ROM that you currently have flashed (and running) and then run:
- $ sudo ./flashrom -p internal -r libreboot.rom
- Notice that this is using "-r" (read) instead of "-w" (write). - This will create a dump (copy) of your current firmware and name it libreboot.rom. - You need to take ownership of the file. For example:
- $ sudo chown yourusername:yourusername libreboot.rom
- # chown yourusername:yourusername libreboot.rom -

-
- -

- If you currently have flashed a ROM image from an older version, it is recommended to update first: - basically, modify one of the latest ROM images and then flash it. +

+ ROM images are included pre-compiled in libreboot. You can also dump your current firmware, using flashrom:
+ $ sudo flashrom -p internal -r libreboot.rom

Troubleshooting

- A user reported that segmentation faults occur with cbfstool - when using this procedure depending on the size of the grub.cfg being re-insterted. - In his case, a minimum size of 857 bytes was required. This could (at the time of - this release) be a bug in cbfstool that should be investigated with the coreboot - community. If cbfstool segfaults, then keep this in mind. 'strace' (or gdb? clang?) - could be used for debugging. This was in libreboot 5th release (based on coreboot - from late 2013), and I'm not sure if the issue persists in the current releases. - I have not been able to reproduce it. strace (from that user) is here: - cbfstool_libreboot5_strace. - The issue has been reported by a few users, so it does not happen all the time: - this bug (if it still exists) could (should) be reproduced. -
