Re-compilation Linux kernel > make deb-pkg

Tags: #<Tag:0x00007ff8ef76e568>

Bonjour,

Je viens « de tester » de compiler un noyau Linux en partant des sources de kernel.org :wink: et cela en créant de packages debian.

Style çà doit bien faire 15 ans je n’ai pas compilé :ok_hand: :rofl:

Je crois que ce n’est pas conseillé pour « un newbe de la compile » comme moi, mais c’est pour apprendre et, que surtout j’étais sur un kernel 5.x et que j’ai compilé un kernel 6.x - Tout va buguer.

J’ai suivis cette documentation debian - 8.10. Compiling a Kernel en compilant un kernel v6.x que j’ai appelé « ninja » pour Linux kernel version history - Releases 6.x.y - « Hurr durr I’ma ninja sloth » :smiley:

J’ajoute ce lien « Kernel Compilation in Debian Linux » et celle-ci « Debian Linux Kernel Handbook »

Comme c’est écrit ici :

Si vous choisissez de compiler votre propre noyau, vous devez en accepter les conséquences : Debian ne peut pas garantir les mises à jour de sécurité pour votre noyau personnalisé. En conservant le noyau fourni par Debian, vous bénéficiez des mises à jour préparées par l’équipe de sécurité du projet Debian.

Préparation :

root@vps:~ # apt install build-essential fakeroot bc python bison flex libelf-dev libssl-dev libncurses-dev dwarves lz4

root@vps:~ # mkdir kernel; cd kernel
root@vps:~/kernel # wget https://mirrors.edge.kernel.org/pub/linux/kernel/v6.x/linux-6.0.9.tar.xz
root@vps:~/kernel # wget https://mirrors.edge.kernel.org/pub/linux/kernel/v6.x/linux-6.0.9.tar.sign
root@vps:~/kernel # unxz -c linux-6.0.9.tar.xz | gpg --verify linux-6.0.9.tar.sign -
root@vps:~/kernel # tar -xaf linux-6.0.9.tar.xz
root@vps:~/kernel # cp -rp linux-6.0.9 /usr/src/

root@vps:~/kernel # cd /usr/src/
root@vps:/usr/src # ln -snf linux-6.0.9/ linux
root@vps:/usr/src # cp /boot/config-$(uname -r) /usr/src/linux/.config
root@vps:/usr/src # cd linux

root@vps:/usr/src/linux # mkdir debian/certs/

Pour installer le noyau Linux :

root@vps:~ # dpkg -i linux-libc-dev_6.0.9-1_amd64.deb
root@vps:~ # dpkg -i linux-image-6.0.9-ninja_6.0.9-1_amd64.deb
root@vps:~ # dpkg - i linux-headers-6.0.9-ninja_6.0.9-1_amd64.deb

Puis redémarrer :

root@vps:~ # reboot

Pour se retrouver sur un kernel 6.0.9.

root@vps:~ # uname -a
Linux vps 6.0.9-ninja #1 SMP PREEMPT_DYNAMIC Sun Dec 11 18:34:18 UTC 2022 x86_64 GNU/Linux

Je souhaiterais savoir à quoi servent ces fichiers après avoir lu « Upstream (développement logiciel) (en) , se dit d’un projet logiciel donné qui sert de base à un ou plusieurs autres, qualifiés pour leur part de downstream (comme par exemple le noyau Linux joue le rôle d’ upstream pour les distributions GNU/Linux). »

  4. linux-upstream_6.0.9-1_amd64.changes
  5. linux-upstream_6.0.9.orig.tar.gz

Donc, j’essaie de re-compiler avec d’autres valeurs dans la « .config » mais quand je relance la compilation du noyeau çà plante.

Note de Moi-même 19h25 :

À la place de « $(make kernelversion)-1 » → → « $(make kernelversion)-2 »
il aurait été préférable que je mette « $(make kernelversion)-0.1 » → → « $(make kernelversion)-0.2 » etc, n’est-ce pas ?

Si vous avez des informations ? Qui peut m’aider ?

Merci.
Romain

J’ajoute une question :

Une fois que je suis en noyau v6.x il doit falloir que je full-upgrade ou un truc du genre ? Que je change mes dépôts et tout çà ?

N’est-ce pas ?

C’est pour m’amuser à « essayer » d’avoir une super distribution new génération, perso :yum: À « m’essayer » de faire un module, de le signer, de l’implanter au système et de m’en servir.

DKMS : Dynamic Kernel Module Support (ou System)
MOK : Machine Owner Key (SecureBoot)


Debian WiKi FR : Modules du Kernel Linux :

Sous Debian, le module peut être installé à partir de trois différents types de sources :

  • Des modules du noyau amont (upstream) Linux : ils sont installés à partir du paquet linux-image-*.

  • Modules supplémentaires, qui ne sont pas dans le noyau amont de Linux. Il sont généralement construits en utilisant dkms. Les modules disponibles peuvent être listés en exécutant apt rdepends dkms.

  • Un mécanisme plus ancien et moins flexible pour construire des modules supplémentaires est → module-assistant.


The Linux Kernel Module Programming Guide : Chapter 2. Hello World → 2.1. Hello, World (part 1): The Simplest Module


Debian Kernel-Team handbook (Manuel)

Chapitre 4. Tâches courantes liées au noyau

4.5. Construire un noyau personnalisé à partir de la source du noyau Debian

4.6. Construire un noyau personnalisé à partir de la source du noyau « vierge »
Construire un noyau à partir de la source du noyau « vierge » (aussi parfois appelée « vanille »), distribué depuis www.kernel.org et ses miroirs, peut être parfois utile pour le débogage ou dans les situations où une version plus récente du noyau est souhaitée.

4.7. Modules de noyau hors arbre
Certains modules du noyau ne sont pas inclus dans la source du noyau en amont ou Debian, mais sont fournis en tant que packages source tiers. Il y a de fortes chances que l’archive Debian contienne la source des modules du noyau, empaquetés pour être utilisés avec le Dynamic Kernel Module System (DKMS), avec un nom de paquet se terminant par -dkms. Alternativement, il peut être empaqueté pour être utilisé avec module-assistant (m-a) de Debian, avec un nom de paquet se terminant par -source.

Bonsoir,

J’ai réussis à recompiler le noyau. J’ai utilisé « make bindeb-pkg » au lieu de « make deb-pkg ».

J’ai trouvé l’info ici. À priori, si j’ai bien compris, c’est parce que l’on part de la version par default « uname -r » (6.0.9-ninja) et on créait la révision #2 - çà doit être cela.

Le noyau est toujours de version :

root@vps:~ # uname -r
6.0.9-ninja

Mais il y a une « révision » je crois que l’on appelle çà comme çà, les #num.

root@vps:~ # uname -a
Linux vps 6.0.9-ninja #2 SMP PREEMPT_DYNAMIC Thu Dec 15 19:58:40 UTC 2022 x86_64 GNU/Linux

C’était un autre post mais j’ai réussis à activer mon « ppp » en activant les modules dans le kernel.

Salutations,
Romain

Bonne soirée à vous.

En passant, bonsoir.

Je cherchais comment patcher le #kernel Linux (entre temps j’ai installé le kernel v6.1.0).

Voici la procédure avec le patch 6.1.2 :

root@vps:/usr/src # wget https://cdn.kernel.org/pub/linux/kernel/v6.x/patch-6.1.2.xz
root@vps:/usr/src # xz -k -d patch-6.1.2.xz
root@vps:/usr/src # cd linux
root@vps:/usr/src/linux # patch -p1 < ../patch-6.1.2
patching file Documentation/ABI/stable/sysfs-driver-dma-idxd
patching file Documentation/ABI/testing/sysfs-bus-spi-devices-spi-nor
[....]
patching file Makefile
patching file arch/Kconfig
patching file arch/alpha/include/asm/thread_info.h
patching file arch/alpha/kernel/entry.S
[....]

Et voilà c’est bon.

root@vps:/usr/src/linux # make kernelversion
6.1.2

root@vps:/usr/src/linux # uname -a
Linux vps 6.1.0-ninja #1 SMP PREEMPT_DYNAMIC Wed Jan  4 01:36:54 CET 2023 x86_64 GNU/Linux

Il faut maintenant recompiler le noyau, par exemple…

root@vps:/usr/src/linux # make bindeb-pkg LOCALVERSION=-ninja KDEB_PKGVERSION=$(make kernelversion)-1

Et installer les nouveaux package deb et reboot.

root@vps:/usr/src/ # dpkg -i linux-libc-dev_6.1.2-1_amd64.deb
root@vps:/usr/src/ # dpkg -i linux-image-6.1.0-ninja_6.1.2-1_amd64.deb

root@vps:/usr/src/ # reboot

root@vps:~ # uname -a
Linux vps 6.1.2-ninja #1 SMP PREEMPT_DYNAMIC Wed Jan  4 02:49:54 CET 2023 x86_64 GNU/Linux

J’ai trouvé l’information sur Debian-facile.orgNoyau linux / Wiki / Debian-facile.

Histoire de suivre le fil :slight_smile:

Pour re-patcher, il me semble qu’il faut revenir / dé-patcher (reverse) le répertoire courant de /usr/src/linux et le patcher avec le dernier patch.

Exemple :

root@vps:/usr/src/linux # patch -p1 -R < ../patch-6.1.2
root@vps:/usr/src/linux # patch -p1 < ../patch-6.1.4

Et recompiler puis rebooter.

root@vps:~ # uname -a
Linux vps 6.1.4-ninja #1 SMP PREEMPT_DYNAMIC Sun Jan  8 06:11:10 CET 2023 x86_64 GNU/Linux
