 |
|
Hello,
Information about my system configuration (kernel in use, profile, emerge --info, etc) here.
What I try to do:
From this topic (Guidance needed to setup SELinux) I try to recompile my kernel, after creating a .config into /usr/src/linux with xconfig, I compile it successfully (at least, no error), then try to run make install.
What is my problem:
The command make install return this error:

Not being in ease with these operation I done only a few times in my life, I'm requiring assistance please :) !
As a note, please see this with some comments from another user.
He's supposing by installing the package sys-kernel/gentoo-sources it made a conflict on my system, because I installed it with dist-kernel as explained here in the handbook.
This is all the packages installed on my machine in the sys-kernel/ category:
| Code: | [IP-] [ ] sys-kernel/dracut-060_pre20240104-r4:0
[IP-] [ ] sys-kernel/gentoo-kernel-6.6.30:6.6.30
[IP-] [ ] sys-kernel/gentoo-sources-6.6.30:6.6.30
[IP-] [ ] sys-kernel/installkernel-28:0
[IP-] [ ] sys-kernel/linux-firmware-20240410:0
[IP-] [ ] sys-kernel/linux-headers-6.6-r1:0 |
So, from the user comment above, I can try to guess that having sys-kernel/gentoo-kernel-6.6.30 & sys-kernel/gentoo-sources-6.6.30 at the same time is not something you want, but I was not aware of that.
Still if I understand, I should have used this method while installing my Gentoo. Is that correct ?
If it's correct, I guess I have to remove sys-kernel/gentoo-kernel for keeping only sys-kernel/gentoo-sources, compile it as I tried before, and then make install will actually install it, instead of managing the kernel version with portage ? Only what portage will do is updating the package sys-kernel/gentoo-sources, to have the usual Gentoo Linux kernel with my modification (in this case for now, having all needed to use SELinux and enable it from the kernel at boot).
Am I right or taking the wrong path ?

your modules folder
| Code: | | 6.6.30-gentoo-dist-hardened |
the install is looking for >>> Cannot find module directory /lib/modules/6.6.30-gentoo/
you mixed up your kernel folders somehow !?

Hello, I did noticed that but I think I wasn't stating it in my topic, of course it miss something here  ! Sorry.
But, what do you mean by I mixed up my kernel folders ?
---
While installing, I used the dist-kernel way, compiling it myself.
Later, to enable SELinux, I installed gentoo-sources and then tried to compile it.
From what I understood, the problem is located here: Having disk-kernel & gentoo-sources.
---
Should I remove dist-kernel and install a kernel from gentoo-sources I compiled myself ?
Oldfashionnedcow was speaking about chrooting. I guess I'll have to:
1/ Chroot
2/ Remove the dist-kernel
3/ Reboot into a chroot
4/ make & make install my new kermel from gentoo-sources, hardened, 6.6.30.
5/ eselect profile set it
6/ Restart
^ this is just my guess for now.

kgdrenefort,
You have correctly identify the issue, have both gentoo-source and gentoo-kernel at same time is not advised.
sys-kernel/gentoo-kernel design is use Portage(emerge) to manage the kernel life cycle, whereas the sys-kernel/gentoo-source is design to let user manage the compile/install cycle.
Have sys-kernel/gentoo-kernel does not prevent you from change kernel options to customise to your need so I suggest you remove sys-kernel/gentoo-source. However you should make copy of your gentoo-sources .config file. so your hard worked changes will not lost.
Having said above, you can opt to keep sys-kernel/gentoo-sources and remove sys-kernel/gentoo-kernel. Using sys-kernel/gentoo-source you have full control of how to build kernel in your way and how to install into location of your choose. but you should understood the booting sequence of your machine before your try that.
I am not entirely sure the sys-kernel/gentoo-kernel life cycle management. but I think /etc/portage/sys-kernel/ should have a copy of your gentoo-kernel's .config file. you can apply your sys-kerne;/gentoo-sources configuration changes and run emerge to rebuild it.
P.S. Are you sure the sys-kernel/gentoo-kernel(hardened) does not have everything your need for testing selinux? my test show lots of selinux already enabled | Code: | 58eace052d6a /etc/portage/savedconfig/sys-kernel # grep -i selinux gentoo-kernel-6.6.30
CONFIG_SECURITY_SELINUX=y
CONFIG_SECURITY_SELINUX_BOOTPARAM=y
CONFIG_SECURITY_SELINUX_DEVELOP=y
CONFIG_SECURITY_SELINUX_AVC_STATS=y
CONFIG_SECURITY_SELINUX_SIDTAB_HASH_BITS=9
CONFIG_SECURITY_SELINUX_SID2STR_CACHE_SIZE=256
# CONFIG_SECURITY_SELINUX_DEBUG is not set
# CONFIG_DEFAULT_SECURITY_SELINUX is not set |

This configuration is fine, you can install as many different versions of the same kernel version as you want. Note though that one may overwrite the other.
Something else is going wrong, but I am a bit confused about what you are doing, Which kernel are you running 'make install' for? the dist-kernel or your custom kernel? Both make install and make modules_install should take the same kernel version string so the later should always be able to find the modules.
I suspect that you are not installing the kernel you think you are installing, or maybe forgot to run 'make modules_install'

Hello and thanks for the reply.
I was on other problem so I kind of forget a bit how I proceed.
I'll try to restart the process for scratch and try to remove gentoo-sources.
Will get back to this topic with problems or telling why it was bad and how I fixed it.

Hello,
So I think I really misunderstood stuff, explaining a lot.
From the command pingtoo showed, this is what I have in my dist-kernel:
| Code: | # grep -i selinux gentoo-kernel-6.6.30
CONFIG_SECURITY_SELINUX=y
CONFIG_SECURITY_SELINUX_BOOTPARAM=y
CONFIG_SECURITY_SELINUX_DEVELOP=y
CONFIG_SECURITY_SELINUX_AVC_STATS=y
CONFIG_SECURITY_SELINUX_SIDTAB_HASH_BITS=9
CONFIG_SECURITY_SELINUX_SID2STR_CACHE_SIZE=256
# CONFIG_SECURITY_SELINUX_DEBUG is not set
# CONFIG_DEFAULT_SECURITY_SELINUX is not set |
Meanings I already have these options enabled.
Could someone confirm that everything is ok ?
I'll try to keep going anyway, worst case I have backups.
PS: I removed gentoo-source.
Regards,
GASPARD DE RENEFORT Kévin

Can you define what do you mean "everything is ok"? are you asking is those setting is enough for enable selinux? I believe it is "yes" but I am no selinux expert so I don't know what is you trying to archive. So if you can put down more detail explain than someone who better understand selinux can give better guidance.
BTW, from your wiki I know you are already running on a sys-kernel/gentoo-kernel. so may be you can use this running kernel as base to explain what difficulty you encounter. |

Hello,
This topic was sadly pretty useless, my problem wasn't a kernel issue, it (dist-kernel) allows from start SELinux, just need to boot it with lsm=linux and it's enabled.
I close this. Thanks nonetheless for your time.
