Build aditional modules for vyos, linux-source package

silencer · August 5, 2020, 11:04am

Hi,
regarding to this article: Build VyOS — VyOS 1.4.x (sagitta) documentation - I’m looking for linux-source package.
In the following location, there is no linux-source deb package:
http://dev.packages.vyos.net/repositories/current/pool/main/l/linux-4.19.134-amd64-vyos/

Is there any other location?
Is the vyos kernel modules building procedure still valid?
I’m using ver 1.3

Another question: Is is possible to install packages from Debian repository?

Thanks in advance for any hints.

Hi @silencer,
We no longer keep a fork of the kernel source, since we no longer need to patch it as heavily as we once had to.
You can find the kernel package build scripts at vyos-build/packages/linux-kernel at current · vyos/vyos-build · GitHub

Hi @dmbaturin
Thanks for the explanation!
I’ve successfully build linux-image package. Now I got following issue when I tried to install it:

dpkg -i linux-image-4.19.134-amd64-vyos_4.19.134-1_amd64.deb
(Reading database … 77268 files and directories currently installed.)

Errors were encountered while processing:

It looks like there is a problem with /usr/sbin/grub-probe which not recognized overlay filesystem.
What is the “feng shui” with kernel deb package installation?
Is there any wiki describing this procedure?

I appreciate your help!

Any ideas, how to install linux-image package?

Dmitry · August 19, 2020, 8:12am

Hello @silencer, you can check is kernel added to /boot

 sudo ls -la /boot/

and try to update initramfs manually

sudo /usr/sbin/update-initramfs -u

Tell me if this works for you, in another case I will try to reproduce it locally

silencer · August 26, 2020, 9:00am

Hi Dmitry,
thanks a lot for the suggestion.
Looks like that start update-initramfs manually works well:
update-initramfs -u -k all
update-initramfs: Generating /boot/initrd.img-4.19.134-amd64-vyos
live-boot: core filesystems devices utils udev wget blockdev.
update-initramfs: Generating /boot/initrd.img-4.19.134-amd64-vyos-mlnx
live-boot: core filesystems devices utils udev wget blockdev.

-rw------- 1 root root 26675415 Aug 26 08:55 initrd.img-4.19.134-amd64-vyos-mlnx

Unfortunately, dpkg left unconfigured packages, so there is a little mess in OS:

apt-get -f install

What I did wrong?

Hello @silencer, I think you need to try to build kernel like this does vyos-build

github.com

vyos/vyos-build/blob/current/packages/linux-kernel/build-kernel.sh

#!/bin/bash
CWD=$(pwd)
KERNEL_SRC=linux

if [ ! -d ${KERNEL_SRC} ]; then
    echo "Linux Kernel source directory does not exists, please 'git clone'"
    exit 1
fi

echo "I: Copy Kernel config (x86_64_vyos_defconfig) to Kernel Source"
cp -rv arch/ ${KERNEL_SRC}/

cd ${KERNEL_SRC}

echo "I: clean modified files"
git reset --hard HEAD

KERNEL_VERSION=$(make kernelversion)
KERNEL_SUFFIX=-$(dpkg --print-architecture)-vyos

Hi Dmitry,
that’s exactly what I did, and the kernel was built without any issues.
The problem is with installation of linux image deb package, because of read only filesystem.

I appreciate your help.

Dmitry · September 4, 2020, 5:36pm

Hi @silencer, can you confirm that you have and trying to install on the installed image.

Hello @silencer, try this hack

sudo mv /etc/kernel/postrm.d/zz-update-grub /etc/kernel/postrm.d/zz-update-grub.back

And try to install again

sudo dpkg -i linux-image-4.19.134-amd64-vyos_4.19.134-1_amd64.deb

silencer · October 20, 2020, 10:01am

Hi Dmitry,
I apologize for long time without respond. I was out of office due to illness.
I moved zz-update-grub, but there is still the same issue:

update-initramfs: Generating /boot/initrd.img-4.19.134-amd64-vyos
live-boot: core filesystems devices utils udev wget blockdev.
/usr/sbin/grub-probe: error: failed to get canonical path of `overlay’.

Hello @silencer, do you have a chance to provide access to this device, I hope this device not in production.

silencer · October 22, 2020, 10:23am

Sure, no problem.
How can I send you more details about access?

Dmitry · October 22, 2020, 10:34am

You can send credentials via forum direct messages.
