Hi,

i have compiled a first test kernel 6.18 for x86_64.

https://people.ipfire.org/~arne_f/highly-experimental/kernel/

please help testing and report your findings...

Re: Kernel 6.18 fist tests...

[Adolf Belka]

Hi Arne,

I have tried it out on a vm clone running CU199 Testing.

In the readme.txt file I think you meant to have

tar xvaf KERNEL-ARCHIV.tar.xz -C /

instead of

tar xvaf KERNEL-ARCHIV.tar.xz -C \

At least it only extracted for me with the / and not the \.

I then ran the dracut command and got the following messages.

sudo dracut --regenerate-all --force
dracut[I]: Executing: /usr/bin/dracut --kver=6.12.58-ipfire --force
dracut[E]: Module 'btrfs' depends on module 'initqueue', which can't be installed

Not sure about the "module 'initqueue', which can't be installed" bits.

After the above last line I then got

cp: error writing '/boot/initramfs-6.12.58-ipfire.img.tmp': No space left on device

So I suspect I need to make the IPFire vm disk larger.

Will give that a try later but would like to know if there is anything I need to do with regard to the initqueue module that is mentioned in the dracut output.

Regards,

Adolf.

The problem was that I made a clone of a system that I had tested out upgrading from CU150 to CU198 and the boot size was obviously smaller back in CU150 as I only have 110MB but the more current systems have 488MB so I will create a clone of one of my newer systems and repeat the test.

Repeated with a newer IPFire vm which had a 488MB boot partition and the dracut section went fine with no problems beside the initqueue module not being able to be installed. However that did not seem to cause a problem with the grub-mkconfig command or the subsequent reboot.

I will evaluate the install tomorrow to check if anything has a problem.

Re: Kernel 6.18 fist tests...

Hello Adolf,

The initqueue module is probably quite important. As far as I know it kind of replaces some systemd functionality which we don’t have.

But looking at our root file, it is adding some systemd unit files:

  https://git.ipfire.org/?p=ipfire-2.x.git;a=blob;f=config/rootfiles/common/dracut-ng;hb=d656b7af6411d0306513b853a552f56d6713c174#l484

We might have found a breaking change in dracut-ng if we don’t properly support mdraid any more.

Lacking support for btrfs in the initramdisk could be less severe, but that also needs to be tested. @Stefan, will you do this for c199?

but that should then be presumably raised as an issue with dracut-ng as if it worked with the old dracut it should work with dracut-ng as version 100 was said to be a drop-in replacement for the old version.

We are currently on version 108 and I just found in the changelog for that version the following change.

--------------------------
feat(initqueue): factor out initqueue into its own module
This PR allows excluding dracut initqueue module, while
including the base or the dracut-systemd module.

Factoring out functionality into its own module
allows to better control to include or exclude the
functionality.
--------------------------

https://github.com/dracut-ng/dracut-ng/commit/3daf67830d8db3b12bc45eef9f8f29f606192db9

So it looks like it is a module that has to be explicitly specified now whereas in the past it was part of dracut base.

Adolf.

Three of those files are related to systemd but one is the same as used to be in the base collection but was moved to this separate set in version 108.

When I did the package update, I commented out all new entries in the rootfile that weren't previously in the rootfile. Therefore the initqueue set are all commented out but as it had been moved out from the base it needed to be included.

I am running a build with all of the initqueue entries uncommented (although probably, the ones related to systemd could be left commented) and I will then do an install with that build and then try the kernel update followed by the dracut command again and see if it then works for the initqueue module.

Well report back when I have the results.

Regards,

Adolf.

I can report that all required modules are now able to be included, including initqueue and all modules are now correctly installed including btrfs, lvm and mdraid that had a problem before.

I will submit a patch to correct the dracut-ng rootfile.

Re: Kernel 6.18 fist tests...

[Adolf Belka]

Hi Arne,

With the patch fix for the initqueue issue in place I have been running IPFire with that new kernel and testing out various things.

I am not sure what aspects of IPfire would be most likely to be affected by the change to the kernel, so I have just been testing various elements of IPFire. Everything I have tried has worked without any issues.

OpenVPN, WireGuard and IPSec connections have all worked, both RW and N2N with the latter being between a system with 6.18.0 and all other IPFire VM's with 6.12.58

Regards,

Adolf.

Re: Kernel 6.18 fist tests...

[Adam Gibbons]

[-- Attachment #1: Type: text/plain, Size: 9540 bytes --]

Hi Arne, Adolf, all,
Just chiming in with my own testing experience.

I updated to the latest nightly (which has the dracut-ng initqueue fix) and then applied the 6.18 kernel. Small things I hit: the readme had "-C " instead of "-C /" for the tar command, and there was a typo in the dracut command ("regenrate" instead of "regenerate"). Easy fixes, though. :)

Since then it's been running solidly for over 24 hours now. No odd behaviour at all – everything feels normal, and Observium (which monitors the box) isn't showing anything unusual either.

I've noticed that Linux 6.18.1 was released recently too, so I'll grab Arne's build of that next and give it a go soon.

For reference, my current test box is an older i5-4200U with four Intel I211 NICs. I also have a newer Intel N305 (with I226-V NICs) ready, so I'll move the test over to that soon – mainly curious to see how p-states and power management are behaving in 6.18.

Thanks Arne for building these, really helpful to get it tested early.

Cheers,
Adam

Hi Arne, hi all,

I have been running kernel-6.18.1-ipfire.x86_64 for over a day now on
real (quite old) hardware and everything is working perfectly so far.

Hardware:
- SECO 0949 motherboard
- Intel Atom N2600 @ 1.6 GHz (4 threads), 2 GB RAM
- 2× Realtek RTL8111/8168 (r8169 driver) – green0 and red0 at 100 Mbps
- USB Wi-Fi: Ralink RT5572 (rt2800usb) – blue0
- Crucial BX500 240 GB SSD

Installation as described in the README (with fixed typo) went
smoothly. dracut correctly included the initqueue module, and grub-
mkconfig placed the new kernel at the top.

Tested (all working flawlessly):
- Normal boot (multiple reboots)
- Web interface
- Internet access via RED
- Clients browsing normally behind GREEN and BLUE (Wi-Fi stable)
- OpenVPN tunnel (tun0) starts, routes are set
- WireGuard interface (wg0) present
- No kernel errors/warnings in dmesg
- System stable for 18+ hours, normal RAM usage, no swap

Additional stress tests:
- CPU stress (stress --cpu 4 for ~15 minutes):
  - Load average ~4.0–4.3 (100% on all threads)
  - CPU frequency stable at 1596 MHz (no throttling)
  - Temperatures max. 56°C (Core 1) / 55°C (zone) – safe and cooled
down quickly
  - No kernel errors

- Network tests:
  - LAN TCP (client to IPFire green0): stable 94 Mbits/sec (full link
speed)
  - LAN UDP overload: ~60 Mbits/sec with only 4.4% loss (expected on
100 Mbps link)
  - Local loopback TCP (4 parallel streams): ~2.71 Gbits/sec aggregate
  - Local loopback UDP: 25.3 Mbits/sec with 0% loss
  - No packet errors on r8169 interfaces (ethtool -S shows all error
counters at 0)
  - No drops in /proc/net/softnet_stat

Conclusion: On this older low-power hardware, kernel 6.18.1 runs
absolutely stable with no noticeable regressions – network performance
is excellent and the system handles both CPU and network load very
well.

I will keep it running as my daily driver and report if anything
changes.

Many thanks for the test builds, Arne – great work!

Best,

Erik

As a side note, the new kernel delivers also the OpenVPN data channel
offload modul

https://blog.openvpn.net/openvpn-dco-added-to-linux-kernel-2025 . The
new openvpn-2.7_rc3 version supports now also the new ovpn DCO Linux
kernel module
https://community.openvpn.net/Downloads#openvpn-27_rc3-released-28-november-2025
which is native in  which works good after a first look over.
There was the need to delete the `--enable-iproute2` and add the `--
enable-dco` compiletime options. There is also the need to Remove or
change the `--data-ciphers-fallback` flag to an AEAD cipher in
server.conf , after that:
- Server starts with DCO
  - Logs show explicit DCO activation:
    "net_iface_new: add tun0 type ovpn"
    "DCO device tun0 opened"
    "ovpn-dco device [tun0] opened"
    "dco_new_peer", "dco_install_key", "dco_set_peer"
  - Data channel uses AES-256-GCM in kernel mode
  - Server-side DCO active even with 2.6 client

Some more infos.

Erik

P.S.: OpenVPN-2.7 uses now

`Control Channel: TLSv1.3, cipher TLSv1.3 TLS_AES_256_GCM_SHA384, peer
certificate: 4096 bits RSA, signature: RSA-SHA256, peer temporary key:
768 bits X25519MLKEM768, peer signing digest/type: rsa_pss_rsae_sha256
RSASSA-PSS, key agreement: X25519MLKEM768`

so with default config, hybrid post-quantum key exchange
(X25519MLKEM768 = X25519 + Kyber-768/ML-KEM-768) is available :-) .
