Full root filesystem encryption on an Armbian system

(new, fully rewritten, replaces my earlier tutorial on this topic)

 

MMGen (https://github.com/mmgen)

 

This tutorial provides detailed, step-by-step instructions for setting up full root filesystem encryption on an Armbian system.  The disk can be unlocked remotely via SSH or the serial console, permitting unattended bootup.

 

An automated script that performs the same steps, saving you much time and effort, can be found at https://github.com/mmgen/mmgen-geek-tools

 

Note that unlike my earlier tutorial all steps are performed within a running Armbian system.

 

The tutorial is known to work with the following board/image combinations:

 Orange Pi PC2  Debian Buster mainline / Ubuntu Bionic and Focal legacy
 RockPi 4  Debian Buster mainline / Ubuntu Bionic and Focal legacy
 RockPro 64  Ubuntu Focal mainline
 Odroid HC4  Debian Buster mainline / Ubuntu Focal mainline

 

 

 

 

 

You may have success with other boards/images too. If so, please post the details below (or open an issue in the mmgen-geek-tools Github repository), and I’ll add your board to the list.

 

Requirements:

  • A SoC with a running, upgradeable and Internet-connected Armbian system
  • A blank Micro-SD card and USB card reader, or, alternatively, a blank eMMC installed on the board
  • The ability to edit text files and do simple administrative tasks on the Linux command line

 

Step 1 - Preliminaries

 

All steps in this tutorial are performed as root user on a running Armbian system (the “host”).

 

The encrypted system (the “target”) will be created on a blank micro-SD card.  If your board has an eMMC not currently in use, the system can be created on it instead.

 

Architecture of host and target (e.g. 64-bit or 32-bit ARM) must be the same.

 

For best results, the host and target hardware should also be identical or similar.  Building on a host with more memory than the target, for example, may lead to disk unlocking failure on the target.

 

If you’re building the target system for the currently running board and with the currently running image, which is the recommended approach, the two preceding points will be a non-issue.

 

Packages will be installed using APT, so the host machine must be Internet-connected and its clock correctly set.

 

 

Step 2 - Upgrade your system and install the cryptsetup-bin package

 

# apt update && apt upgrade
# apt install cryptsetup-bin

 

 

Step 3 - Get and unpack the latest Armbian image for your board

 

Create your build directory:

# mkdir armbenc-build && cd armbenc-build

 

Download the Armbian image of your choice for your board, place it in this directory and unpack:

# xz -dv *.img.xz

 

 

Step 4 - Create mount directories and set up the loop mount

 

Create the mount directories:

# mkdir -p mnt boot root

 

Determine your first free loop device:

# losetup -f

 

Associate the image file with the loop device name displayed by the previous command.  This will be '/dev/loop0' in most cases, but if your output was different, substitute that for '/dev/loop0' in the following steps.

# losetup -P /dev/loop0 *.img

 

Examine the disk image using fdisk on the loop device:

# fdisk -l /dev/loop0

 

The output should look something like this:

Device       Boot Start     End Sectors  Size Id Type
/dev/loop0p1      32768 3489791 3457024  1.7G 83 Linux

 

Make a note of the start sector (32768 in this case).  You’ll need this value in the steps below.

 

Now mount the loop device:

# mount /dev/loop0p1 mnt

 

 

Step 5 - Copy the boot loader to the SD card

 

Insert the blank micro-SD card and card reader into a USB port.

 

Determine the SD card’s device name using 'dmesg' or 'lsblk'.  We’ll assume it to be '/dev/sda', since that’s the most likely case.  If your device name is different, substitute it for '/dev/sda' in the the following steps.  For an eMMC, the device name will probably be '/dev/mmcblk1'.

 

WARNING: if '/dev/sda' refers to some other storage device, running the following commands unchanged will destroy data on that device, so always remember to substitute the correct device name!!!  The best way to eliminate this danger is to disconnect all unused storage devices on the board before proceeding further.

 

Copy the image’s boot loader to the SD card, using the Start sector value from Step 4 as the argument for 'count':

# dd if=$(echo *.img) of=/dev/sda bs=512 count=32768

 

 

Step 6 - Partition the SD card

 

# fdisk /dev/sda

 

At the fdisk prompt, create a new DOS disk label with the 'o' command.  Use the 'n' command to create a primary partition of size +200M beginning at the same Start sector as the disk image.  Type 'p' to view the partition table, which should now look something like this:

Device      Boot  Start      End  Sectors  Size Id Type
/dev/sda1         32768   442367   409600  200M 83 Linux

 

Use 'n' again to create another primary partition beginning one sector after the first partition’s end sector and filling the remainder of the card.  Type 'p' once more to view the partition table:

Device      Boot  Start      End  Sectors  Size Id Type
/dev/sda1         32768   442367   409600  200M 83 Linux
/dev/sda2        442368 30636031 30193664 14.4G 83 Linux

 

Ensure that the first partition’s Start sector matches that of the disk image (32768 in this example) and that the second partition’s Start sector is one greater than the End sector of the first (442368 and 442367, respectively, in this example).  If you’ve made a mistake, use 'd' to delete a partition and start again.


Once everything looks correct, type 'w' to write the partition table to disk.

 

 

Step 7 - Copy the system to the SD card

 

The following commands will create a filesystem on the SD card’s boot partition and copy the boot partition data from the image file to it.  Don’t forget to substitute the correct device name if necessary.  If you’re building the system on an eMMC, the boot partition device is likely to be '/dev/mmcblk1p1' instead of '/dev/sda1'.

 # mkfs.ext4 /dev/sda1            # or '/dev/mmcblk1p1', for an eMMC target
 # e2label /dev/sda1 CRYPTO_BOOT
 # mount /dev/sda1 boot
 # cp -av mnt/boot/* boot
 # (cd boot; ln -s . boot)

 

Create the encrypted root partition.  When prompted for a passphrase, it’s advisable to choose an easy one like 'abc' for now.  The passphrase can be changed later with the 'cryptsetup luksChangeKey' command (type 'man cryptsetup' for details) once your encrypted system is up and running.

# cryptsetup luksFormat /dev/sda2 # or '/dev/mmcblk1p2', for an eMMC target

 

Activate the encrypted root partition and create a filesystem on it:

# cryptsetup luksOpen /dev/sda2 rootfs  # enter your passphrase from above
# mkfs.ext4 /dev/mapper/rootfs

 

Mount the encrypted root partition and copy the system to it:

# mount /dev/mapper/rootfs root
# (cd mnt && rsync -a --info=progress2 --exclude=boot * ../root)
# sync # be patient, this could take a while
# mkdir root/boot
# touch root/root/.no_rootfs_resize

 

Unmount the boot partition and image and free the loop device:

# umount mnt boot
# losetup -d /dev/loop0

 

 

Step 8 - Prepare the target system chroot

 

# BOOT_PART=($(lsblk -l -o NAME,LABEL | grep CRYPTO_BOOT))
# ROOT_PART=${BOOT_PART%1}2
# ROOT_UUID="$(lsblk --nodeps --noheadings --output=UUID /dev/$ROOT_PART)"
# BOOT_UUID="$(lsblk --noheadings --output=UUID /dev/$BOOT_PART)"

# cd root
# mount /dev/$BOOT_PART boot
# mount -o rbind /dev dev
# mount -t proc proc proc
# mount -t sysfs sys sys

 

Copy '/etc/resolv.conf' and '/etc/hosts' so you’ll have a working Internet connection within the chroot:

# cat /etc/resolv.conf > etc/resolv.conf
# cat /etc/hosts > etc/hosts

 

If you’re using non-default APT repositories, you may need to copy their configuration files as well so that 'apt update' and 'apt install' will use them inside the chroot.  Note that you can only do this if the host and target systems have the same distro/version.  If that’s not the case, you’ll have to edit the target files by hand.

# cat /etc/apt/sources.list > etc/apt/sources.list
# cat /etc/apt/sources.list.d/armbian.list > etc/apt/sources.list.d/armbian.list

 

If you’re using an apt proxy, then copy its configuration file too:

# cp /etc/apt/apt.conf.d/*proxy etc/apt/apt.conf.d/

 

 

Step 9 - Edit or create required configuration files in the target system

 

Perform the editing steps below using a text editor of your choice:

  1. Edit 'boot/armbianEnv.txt' so that the 'rootdev', 'console' and 'bootlogo' lines read as follows.  If you’ll be unlocking the disk via the serial console, then use 'console=serial' instead of 'console=display'. Note that enabling the serial console will make it impossible to unlock the disk from the keyboard and monitor, though unlocking via SSH will still work:

    rootdev=/dev/mapper/rootfs
    console=display
    bootlogo=false
    
  2. Edit 'etc/initramfs-tools/initramfs.conf'.  If your board will have a statically configured IP, add the following line to the end of the file, substituting the correct IP in place of 192.168.0.88:

    IP=192.168.0.88:::255.255.255.0::eth0:off
    

    If the board will be configured via DHCP, then edit the DEVICE line as follows:

    DEVICE=eth0
    
  3. If host and target systems are both Debian buster, you may wish add some key modules to the initramfs to avoid a blank display at bootup time.  The easiest way to do this is to add all currently loaded modules as follows:
    # lsmod | cut -d ' ' -f1 | tail -n+2 > etc/initramfs-tools/modules
    
  4. Retrieve the SSH public key from the remote unlocking host and copy it to the target:

    # mkdir -p etc/dropbear-initramfs
    # rsync yourusername@remote_machine:.ssh/id_*.pub etc/dropbear-initramfs/authorized_keys
    

    If you want to unlock the disk from more than one host, then edit the authorized_keys file by hand, adding the required additional keys.

  5. Create 'etc/crypttab':

    # echo "rootfs UUID=$ROOT_UUID none initramfs,luks" > etc/crypttab
    
  6. Create 'etc/fstab':

    # echo '/dev/mapper/rootfs / ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro 0 1' > etc/fstab
    # echo "UUID=$BOOT_UUID /boot ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro 0 2" >> etc/fstab
    # echo 'tmpfs /tmp tmpfs defaults,nosuid 0 0' >> etc/fstab
    
  7. Create the dropbear configuration file:

    # echo 'DROPBEAR_OPTIONS="-p 2222"' > etc/dropbear-initramfs/config
    # echo 'DROPBEAR=y' >> etc/dropbear-initramfs/config
    
  8. If the target is Ubuntu bionic, then a deprecated environment variable must be set as follows:

    # echo 'export CRYPTSETUP=y' > etc/initramfs-tools/conf.d/cryptsetup

     

  9. Set up automatic disk unlock prompt. Performing this optional step will cause the disk password prompt to appear automatically when you log in remotely via SSH to unlock the disk. Using your text editor, create the file 'etc/initramfs-tools/hooks/cryptroot-unlock.sh' with the following contents:
    #!/bin/sh
    
    if [ "$1" = 'prereqs' ]; then echo 'dropbear-initramfs'; exit 0; fi
    
    . /usr/share/initramfs-tools/hook-functions
    
    source='/tmp/cryptroot-unlock-profile'
    
    root_home=$(echo $DESTDIR/root-*)
    root_home=${root_home#$DESTDIR}
    
    echo 'if [ "$SSH_CLIENT" ]; then /usr/bin/cryptroot-unlock; fi' > $source
    
    copy_file ssh_login_profile $source $root_home/.profile
    
    exit 0
    

    Save the file and execute the command:

    chmod 755 'etc/initramfs-tools/hooks/cryptroot-unlock.sh'

     

 

Step 10 - Chroot into the target system, install packages and configure

 

Now chroot into the encrypted system.  All remaining steps will be performed inside the chroot:

# chroot .

 

Install the cryptsetup package and the dropbear SSH server:

# apt update
# echo 'force-confdef' > /root/.dpkg.cfg
# apt --yes install cryptsetup-initramfs dropbear-initramfs # for a buster or focal image
# apt --yes install cryptsetup dropbear-initramfs           # for a bionic image
# rm /root/.dpkg.cfg

 

Make sure everything was included in the initramfs (all three commands should produce output):

# lsinitramfs /boot/initrd.img* | grep 'usr.*cryptsetup'
# lsinitramfs /boot/initrd.img* | grep dropbear
# lsinitramfs /boot/initrd.img* | grep authorized_keys

 

Your work is finished! Exit the chroot and shut down the board:

# exit
# halt -p

 

Insert your freshly written SD card into the board’s main SD slot (or, if the target is an eMMC, just remove the SD card from that slot) and reboot.


Unlock the disk by executing the following command on your remote unlocking machine, substituting the correct IP address if necessary:

$ ssh -p 2222 root@192.168.0.88

 

If you performed step 9.10 above, the disk password prompt should appear automatically after login.  If not, you must enter the command 'cryptroot-unlock'.

 

You may also unlock the disk from the target board’s console if you wish.  Note, however, that certain disk images (RockPi 4 buster mainline, for example) might give you a blank display at startup, so you’ll have to enter your disk password “blindly”.  This bug will hopefully be fixed in the future.


If all went well, your root-filesystem encrypted Armbian system is now up and running!

Donate and support the project!

Thanks for pointing that out!

 

As far as overlap goes, I think this tutorial (and the automated script) has a clear use case, as it creates encrypted Armbian systems without building or compiling anything, which is much easier for most users (the automated script can create a fully configured system on your SD card or eMMC in a matter of minutes).

 

Secondly, the tutorial can be a valuable learning experience for those interested in better understanding disk partitioning, loop devices, LUKS encryption, uBoot, the Linux bootup process, basic administrative commands, etc.

Thanks for the post.
I test the script with Orange Pi zero with the latest Ubuntu Focal image.

Armbian 20.08.1 Focal with Linux 5.8.5-sunxi

After writing to the SD, at booting phase, following error occurs.

I am wondering if this script would break nand-sata-install since the base Armbian images are single partition while the new encrypted image on SD card is having a separate Boot and Root partition. 

 

If this is the case then how can we move the image to eMMC from SD?

 

-R

 

You don't need nand-sata-install, because the tutorial (and script) create the encrypted system directly on the eMMC. This has been tested successfully on the RockPi 4. Would like to hear from users how it works on other boards.

@MMGen anything I need to do additionally to support Orange Pi Zero?

This is not the kind of error I would expect to see. Are you sure you performed all the steps correctly, didn't omit anything? Is the SD card itself in working order? I'll take a look at the Focal Orange Pi Zero image to see if there's anything there that might be causing this error, but I don't have that board to test on, unfortunately.

 

UPDATE: I looked at your image. Some things you might want to check:

 

1) Make sure you're editing armbianEnv.txt correctly. After performing the edits, the file should look like this:

verbosity=1
bootlogo=false
console=display
disp_mode=1920x1080p60
overlay_prefix=sun8i-h3
overlays=usbhost2 usbhost3
rootdev=/dev/mapper/rootfs
rootfstype=ext4

2) In boot.cmd there are two lines beginning with 'setenv rootdev'. Make sure you're deleting the first one.

 

If that doesn't work, there are other things you might try and see whether you get the same or similar error at bootup:

 

1) Use the automated script instead of the tutorial.

2) Try the Buster image instead of Focal.

Also tried with an Opi Zero Plus I had since it is 64bit, following the steps and also using the script.

Boot hangs after 




Starting kernel ...

 

Sorry to hear that. I'm afraid I've run out of options, since I don't have an Opi Zero for testing. If you really need root fs encryption, then you might try building Armbian with the CRYPTROOT_ENABLE option mentioned by @DevShankyin the post above.

I will look into that.
Thanks.

Edit: building Armbian with the CRYPTROOT_ENABLE option works :)

Great step-by-step guide as an alternative to the build option, and also as a training/education for people less familiar with this in general :)

 

I guess it should be safe to assume that if `CRYPTROOT_UNLOCK` works, so should this guide?

 

`CRYPTROOT_ENABLE` confirmed working on:

 

* OdroidC4 (current buster and bullseye tested)

* OdroidHC4 (current buster tested; interactive prompt does not show at boot and seems to stop at "Starting Kernel..." but remote unlock over SSH still works. Additionally, eth0 will only come up again after boot if you issue `ip link set eth0 down; rmmod realtek; sleep 1; modprobe realtek; ip link set eth0 up` after boot)

 

 

Thanks to people in IRC for figuring out the points for the hc4.

No, I wouldn't assume that. See the comments by @sunzone above regarding the Orange Pi Zero.

 

In their case, the problem may be connected with the fact that the OPi Zero requires 'flash-kernel' to set up the boot loader.

 

I think that boards/images that don't depend on flash-kernel should generally work with this tutorial, but I need more test data to confirm that hypothesis.

Thank you for the comprehensive tutorial!

Instead of installing the encrypted system on an SD/eMMC I'd like to move the rootfs to my SSD and keep the boot partition on the SD-card (I'm using the Odroid HC4, unfortunately can't boot directly from SSD). Is it sufficient to edit the armbianEnv.txt-file in the SD-card's boot-partition? Do you have any suggestions on this?

Yes, this should be doable. Create a LUKS partition and ext4 fs on the SSD, copy the root fs to it,  update /etc/crypttab with the new device UUID, mount, chroot and update the initramfs. I haven't tested this myself though, so other steps might be required. But first you should try the tutorial without modification to make sure it works for your board. If it does, please let me know and I'll add the HC4 to the "supported" list.

Whoop, it works, thanks! I've followed the (non-boot) parts in your tutorial. thus I created a single partition on the SSD, formatted it with LUKS/ext4 and copied the rootfs over to my SSD. I've performed some steps on the original (source) OS as well, such as installing dropbear, copying the authorized keys and editing the crypttab and fstab (basically step 9) + update initramfs.

After rebooting and configuring the new rootfs such as providing new root password etc. I've added two lines to the fstab on the new or target-rootfs:

UUID=old-rootfs-uuid-here /oldfs ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro 0 2
/oldfs/boot /boot none bind 0 0

Now the new system is aware of the boot folder. When I run update-initramfs on the new rootfs, the boot folder is updated accordingly. Not sure if this is the best way to do it, suggestions and improvements are welcome.

 

When starting the newly copied system for the first time, I noticed that I couldn't use ssh to login for the first time (with root + password "1234"). Is this expected behaviour?

Glad everything worked! However, the bind mount wasn't necessary. Since you're still booting from the SD/eMMC, the old fstab would have worked unmodified. Can't say why you couldn't log in via SSH initially, but in any case this is a minor issue.

Hello and first things first MANY THANKS for this great tutorial!!!

 

And I think I have discovered a small typo which will cause the tutorial to fail at that particular step. See here


Step 8 - Prepare the target system chroot

 

# BOOT_PART=($(lsblk -l -o NAME,LABEL | grep CRYPTO_BOOT))

# ROOT_PART=${BOOT_PART%1}2

# ROOT_UUID="$(lsblk --nodeps --noheadings --output=UUID /dev/$ROOT_PART)"

# BOOT_UUID="$(lsblk --noheadings --output=UUID /dev/$BOOT_PART)"

 

this line here:


# BOOT_PART=($(lsblk -l -o NAME,LABEL | grep CRYPTO_BOOT))

should be correctly

# BOOT_PART=($(lsblk -l -o NAME,LABEL | grep CRYPTO_ROOT))

,,,BOOT should be ,,,ROOT (see commands above for clarification)

 

Unfortunately, I was not successful with the full encryption. I got an ODROID-HC2 as a gift and wanted to try a full encryption with the latest Armbian. I got stuck already at the beginning. In the requirements it says that you have to do it on an already running Armbian host and on the other hand you have to have a free card/reader on the respective host with which you can write to a free SD card.

Zitat

 

...all steps are performed within a running Armbian system.

 

The tutorial is known to work with the following board/image combinations:

 Orange Pi PC2 Debian Buster mainline / Ubuntu Bionic and Focal legacy

 RockPi 4 Debian Buster mainline / Ubuntu Bionic and Focal legacy

 RockPro 64 Ubuntu Focal mainline

 Odroid HC4 Debian Buster mainline / Ubuntu Focal mainline

A blank Micro-SD card and USB card reader, or, alternatively, a blank eMMC installed on the board

 

 

 

 

 

 

The ODROID-HC2 unfortunately has only one micro-SD slot, but it already has my micro-SD card 1 running on the Armbian Bullseye. I can badly pull out during operation this micro-SD card 1 and instead simply insert the empty micro-SD card 2 :-) I have no external SD-card reader which I could attach to the USB port of my ODROID-HC2. So I tried the following. I just used a USB stick (8GB) instead of the empty SD card 2 (32GB) and wrote all the procedure explained in the tutorial to the USB stick, so the target was the USB stick. After everything was successfully completed I removed the USB stick and the micro-SD2 from the ODROID-HC2 and plugged it into my Linux desktop PC. The USB stick was "sdb" and the microSD card was "sdc". I then cloned the contents of the USB stick I just created to the blank micro-SD card 2.

dd if=/dev/sdb of=/dev/sdc bs=1M && sync

 

but unfortunately it did not work. When I put the microSD card into the ODROID-HC2 and boot then I can neither ping nor connect via dropbear/ssh under the configured port. So it seems that the system is not reachable. I noticed that according to the tutorial you should enter DEVICE=eth0 in boot.ini. However, on my ODROID-HC2 with the Armbian bullseye image, the network interface is enx001e06xxxxxx where the numbers/letters after the prefix enx corresponds to the MAC address of the ODROID-HC2. I wonder if this is the error? Would I then have to enter the hardware MAC address in the boot.ini accordingly so device=enx001e06xxxxxx before I had generated the initram?

 

maybe there are ODROID-HC2 users among you who have already done it and can give help? am curious and looking forward to helpful contributions. Thanks in advance.

Hi again. The error I complained about in the last post related to CRYPTO_BOOT CRYPTO_ROOT in Step8) s not an error, but had been seen/written incorrectly by me. Was my mistake, sorry.

 

However, I just can't get this to work with full encryption on the ODROID-HC2. Whenever I try to start the ODROID-HC2 with the new created full-encrypted microSD card I never see my ODROID-HC online, no IP in the network, no ping, not possible to ssh into the configured 2222 dropbear port.I have now made the following attempts in the meantime:

 

1) booted with the microSD card, quite normal into the Armbian operating system. Then inserted an empty USB stick and transferred with nand-sata-install the root filesystem to the USB stick. The microSD is now only used for booting the /boot partition, the filesystem was swapped to the USB stick. This allows me to easily "umount /boot" and then remove the microSD card while the Armbian OS is running. Then I inserted the second empty microSD into the slot of the ODROID-HC2 and went through the entire tutorial point by point exactly as indicated. For me, the startup sector is 8192, so I configured it accordingly.

 

2) In Step9.1) I have manually created the boot/armbianEnv.txt and fed it with the three lines. In step 9.2 I tried three things. First with device=eth0 to get the lease via DHCP, but it didn't work. Then I tried the manual IP assignment, also with eth0 specification. Did not work either. And last but not least I switched back to DEVICE=eth0 but replaced eth0 with enx001e06123456 because my running Armbian OS uses this interface name where 123456 is the real MAC address of the NIC. But this did not help either.

 

3) In step 9.8) I was unsure if I need the line. What is meant by "If the target system is an Ubuntu bionic?" that confuses me. Surely the target system is Armbian ??? Anyway, I have tried both possibilities. Once without this line and once with this line. However, neither of them worked.

 

In step 10.2) I installed "cryptsetup-initramfs" and "dropbear-initramfs". Did not work. Then I tried the variant by installing also the package "cryptsetup". But again without success.

 

EDIT: I see on the /boot partition unter /boot/boot.ini those lines:


# this is for mainline only
if test "${board_name}" = "xu4"; then setenv fdtfile "exynos5422-odroidxu4.dtb"; fi
if test "${board_name}" = "xu3"; then setenv fdtfile "exynos5422-odroidxu3.dtb"; fi
if test "${board_name}" = "xu3l"; then setenv fdtfile "exynos5422-odroidxu3-lite.dtb"; fi
if test "${board_name}" = "hc1"; then setenv fdtfile "exynos5422-odroidhc1.dtb"; fi

 

ODROID-HC2 seems missing here. Can that cause the trouble ?

 

I have now prepared dozens of times my microSD as described in the instructions but the ODROIC-HC board just does not come online. The LEDs all light up as usual, nothing inconspicuous here. But no ping, no IP in the subnet (I checked by nmap scans and insight in my network router) and so I can't ping the rebooted system at all first.

The ODROID-HC2 also has no video output, which means I have no way to see where the error is, or where it hangs. What else should I try, where could the worm be buried? Hope someone can help me.

Hello all,

 

meanwhile I purchased the USB UART serial kit to watch the u-boot process. I sticked to the tutorial here, I tried many times and as explained before the odroid-hc2 is not reachable when rebooting.

as you see, the ODROID-HC2 asks for the rootfs password. The network is NOT up, but I'd expect it to. Without network one cannot connect and unlock the rootfs as explained in the tutorial. Can anyone dig into it and tell us more? How can this be solved? How do we instruct the network to get enabled BEFORE ? thank you

 

EDIT:

while I wrote this post the serial console throwed additional lines, see here

why does the system fail to init the ethernet network ? I tried both variants in initramfs.conf, DEVICE=eth0 but also with static IP. The serial log above shows the output when I used DEVICE=eth0

Hi,

Good to see you've got the monitor.  Can you check that the correct .dts is being loaded ?  See if the one you should use is 88701 bytes ?

If not you could override the choice in boot.scr (setenv fdtfile .....).

 

Cheers,

Steven

in u-boot process with encrypted rootfs I cannot find anything with the string "dts" but I've found the byte size of 88701 in there:

That was the serial log after I configured the full-disk-encryption as shown here in the tutorial.

As reference in the following you see the serial u-boot log after 1st boot after I flashed the Armbian bullseye:

And for better insight, this is the u-boot log with the failing encrypted rootfs at u-boot verbosity=7 configured, so the log level is 7 (maximum):

Hi,

In one of your previous posts you listed some U-Boot code that changed the fdtfile variable depending on the board name and you noted that your board wasn't mentioned.  The U-Boot log shows it is loading a flattened device tree file that is 88701 bytes long.  Can you check in your /boot/dts directory and check if the .dts file for your board is 88701 bytes ?  Somefile.dts files provide hardware details for the drivers and using the wrong one might cause all sorts of problems.  What I.m checking here is that U-Boot is loading the correct .dts file for your board.

Hi Steven,

 

my /boot partition contains following files:

the original boot.ini of the Armbian Bullseye image at the end looks like that:

[...]

# this is for mainline only
if test "${board_name}" = "xu4"; then setenv fdtfile "exynos5422-odroidxu4.dtb"; fi
if test "${board_name}" = "xu3"; then setenv fdtfile "exynos5422-odroidxu3.dtb"; fi
if test "${board_name}" = "xu3l"; then setenv fdtfile "exynos5422-odroidxu3-lite.dtb"; fi
if test "${board_name}" = "hc1"; then setenv fdtfile "exynos5422-odroidhc1.dtb"; fi

# legacy shares a single DT for all boards
if ext4load mmc 0:1 0x00000000 "/boot/.next" || fatload mmc 0:1 0x00000000 ".next"  || ext4load mmc 0:1 0x00000000 ".next"; then echo "Found mainline kernel configuration"; else setenv fdtfile "exynos5422-odroidxu3.dtb"; fi
ext4load mmc 0:1 0x44000000 /boot/dtb/${fdtfile} || fatload mmc 0:1 0x44000000 dtb/${fdtfile} || ext4load mmc 0:1 0x44000000 dtb/${fdtfile}

# set FDT address
fdt addr 0x44000000

 

As I understand the above code it should detect the correct board and assign the corresponding dtb to the boot process. Nevertheless, to ensure the correct .dtb file is used during the boot process I did following. First I backed up the original ./dtb folder that contained following files and folder:

then I wiped the /boot/dtb content except the correct .dtb which is the odroidxu4.dtb for my board ODROID-HC2, I also kept the overlay folder in that directory. That being said, my /boot/dtb looks like that:

Now it's clear, that it is trying to find the wrong odroidxu3 although my board ODROID-HC2 should be discovered as an odroidxu4. Well, I compared the u-boot serial log of the unencrypted initial Armbian Bullseye image which outputs the string "Found mainline kernel configuration". This string is generated by the boot.ini script, means that the board was discovered correctly and the correct image file was set as result. However, after the encryption it looks to me that this test fails somehow and the legacy image odroidxu3 is assigned, which is wrong of course.

 

I modified the boot.ini and manually assigned the odroidxu4.dtb file to see what happens:

# this is for mainline only
#if test "${board_name}" = "xu4"; then setenv fdtfile "exynos5422-odroidxu4.dtb"; fi
#if test "${board_name}" = "xu3"; then setenv fdtfile "exynos5422-odroidxu3.dtb"; fi
#if test "${board_name}" = "xu3l"; then setenv fdtfile "exynos5422-odroidxu3-lite.dtb"; fi
#if test "${board_name}" = "hc1"; then setenv fdtfile "exynos5422-odroidhc1.dtb"; fi
setenv fdtfile "exynos5422-odroidxu4.dtb"

 

# legacy shares a single DT for all boards
#if ext4load mmc 0:1 0x00000000 "/boot/.next" || fatload mmc 0:1 0x00000000 ".next"  || ext4load mmc 0:1 0x00000000 ".next"; then echo "Found mainline kernel configuration"; else setenv fdtfile "exynos5422-odroidxu3.dtb"; fi
if ext4load mmc 0:1 0x00000000 "/boot/.next" || fatload mmc 0:1 0x00000000 ".next"  || ext4load mmc 0:1 0x00000000 ".next"; then echo "Found mainline kernel configuration"; else echo "manually set fdtfile to exynos5422-odroidxu4.dtb"; fi
ext4load mmc 0:1 0x44000000 /boot/dtb/${fdtfile} || fatload mmc 0:1 0x44000000 dtb/${fdtfile} || ext4load mmc 0:1 0x44000000 dtb/${fdtfile}

 

Now see here, seems we have the correct .dtb file loaded. Looks good...

[   14.871564] r8152 6-1:1.0 enx001e06380848: renamed from eth0

 

but the pre-init scripts are looking for a device called eth0. The armbian image however changed the NIC name from eth0 to enx001e06380848. I guess that is the next issue because the network is not initialized correctly and timed-out?

 

how to solve this? Well, to overcome this in the configuration file /etc/initramfs-tools/initramfs.conf I changed DEVICE=eth0 to DEVICE=enx001e06380848 and then executed in the chroot'ed environment "update-initramfs -u". After this it works like a charm, YES!!!!!!

Armbian 21.08.3 Bullseye ttySAC2

odroidxu4 login:

 

But ... as you see in the log, the OpenSSH server is not up. I cannot login "ssh root@192.168.0.1" although the device is reachable through network via ICMP ping. I have no idea why the OpenSSH server is failing now. Well, made some steps to mitigate the issue.

 

Here's the conclusion so far:

Issue 1)

After introducing the encryption setup as shown here on that tutorial the boot.ini discovering mechanism for the correct board and corresponding image seems to fail. As I suspect the ODROID-HC2 board is not discovered correctly during the test/board_name commands in boot.ini. The default Armbian<foo>.img containt the hidden flag file .next in the boot partition, that's why the boot.ini assigns the correct exynos5422-odroidxu4.dtb for the boot process. However, after introducing the encryption as shown here on the tutorial, this flag file .next was not in the boot partition any more that's why the recognition and aassignment of the needed dtb file fails.

Workaround: either by manually forcing boot.ini to load the odroidxu4.dtb image which will work for the ODROID-HC2 board or better and simple --> don't touch the boot.ini at all and leave it as it is, but simply touch a new zero-byte hidden file called .next into the boot partition. If filename /boot/.next exists it will trigger as mainline configuration and the legacy odroidxu3 won't start and conflict with the HC-2 board thus as result the correct odroidxu4.dtb is loaded which is the correct one for the ODROID-HC2 board.

 

Issue 2)

The configuration line DEVICE=eth0 initially configured as instructed by the tutorial in "/etc/initramfs-tools/initramfs.conf" will fail, because Armbian OS changes the device name in boot process from "eth0" to "enx<mac-address>"

Workaround:  changing the configuration line "DEVICE=eth0" to "DEVICE=enx<mac-address-being-used-in-boot-process>"

 

Issue 3)

As first instance the Dropbear SSH server is executed through initramfs. You can login to it through port 2222 and you're prompted to enter the LUKS password for decrypting /dev/mapper/rootfs. Right after you enter the correct keyphrase, the network interface enx... gets dropped and the dropbear ssh connection is resetted as result. The boot process continues, but OpenSSH won't start.

Workaround: the journal of ssh.service said that no hostkeys were available. I had to use the USB serial UART console for the first initial root login on the ODROID-HC2. After that I was prompted to change the root password and the Armbian setup was finished. I guess this was important, so the hostkeys were generated. After that, the OpenSSH were accessible as expected. Here's the output of the ssh.service journal:

Are issues 1+2 a bug in the current release or is this a bug somewhere happen during this FDE tutorial? If so, do you think they are addressable? Maybe there are some devs in here watching this thread and hopefully can give some insight? Hope the provided u-boot serial console log can assist if needed. Thanks to Steven, who showed me the right direction to nail down the issue(s)

Hi,

Great news that you've got somewhere.

 

With the "eth0" name being changed to "eth............", this occurs because the kernel (or udev or something) wants to include the MAC address in the name.  This can be stopped by adding "net.ifnames=0" in the kernel bootargs command line.

 

I was chasing a bad idea because I figured your board was an "HC2" and U-Boot was intended for an "xu4".  But apparently they're the same or compatible at least.   But note the single line "if" test under the 4 lines that set fdtfile for various boards.  It's a long line that checks for a file called ".next" and if it's not found the code sets fdtfile to ".....xu3".  The check for whatever file was 88701 bytes was a clue.  As you say, adding a dummy file called ".next" to your /boot directory probably would solve the problem here.

 

From a software distribution viewpoint I would add the "net.ifnames=0" to the bootargs so the DEVICE= clause doesn't have to be changed for every board and the standard "DEVICE=eth0" should work for all boards.  Also I don't see why the ".next" file is missing.  Most Armbian distributions contain such a file (size 0) and this is detected by the U-Boot script and tells it to use the mainline kernel (and ....dtb in your case).

 

But it's great that it's working now so I'd leave things as they are and all the work you've done will help anybody else that hits the same problems.

 

Cheers,

Steven
