All Projects

Develop HyperBK (Hyper Berkeley Kernel), a BSD descendant kernel with GPL-compatible licenses preserved, non-compatible ones removed, and new code written under GPL-3 for HyperbolaBSD.

TODO:

• Download OpenBSD kernel source code from OpenBSD site → DONE

• Download LibertyBSD scripts to deblob and rebrand kernel from their scripts. → DONE

• Create a new project in Hyperbola Git called hyperbk. → DONE

• Push source to HyperBK’s project. → DONE

• Rebrand OpenBSD kernel to HyperbolaBSD with LibertyBSD scripts. → DONE

• Rebrand entire code (functions, variable, pointers, etc) under HyperbolaBSD → DONE

• Remove files under non GPL-compatible licenses → DONE

• Import code from another BSD systems under GPL-compatible licenses → IN PROGRESS

• Remove remaining nonfree files don't found from LibertyBSD scripts → IN PROGRESS

• Write new code under GPL-3 → IN PROGRESS

• Package HyperBK for HyperbolaBSD.

PATCHING NOTE

When the check concerns kernel, we obviously want to match with HyperbolaBSD.

Example of triplet check:	hyperbolabsd)
Example of uname -s check:	HyperbolaBSD)
Example of uname -r check:	0.1)
Example of C macro check:	defined(__HyperbolaBSD__)

The unfortunate reality is that x86 computers come encumbered with built-in low-level backdoors like the Intel Management Engine , as well as nonfree boot firmware. This means that users can’t gain full control over their computers, even if they install a free operating system such as Hyperbola GNU/Linux-libre .

Hyperbola is working hard to fix these issues and getting closer every day, but for the time being, this is why many current Respects Your Freedom (RYF) offerings are refurbished older devices.

For the future of free computing, we need support architectures that do not come with such malware pre-installed, and the Power9-based Talos II promises to be a great architecture example for workstations and servers environments where Hyperbola is focused since is a fully free long-term support distribution.

Devices like this are the future of computing that Respects Your Freedom and for that reason it’s a high priority for Hyperbola port all packages for the POWER architecture (power64le).

NOTE: POWER porting is focused only for Hyperbola GNU/Linux-libre .

/sbin/openrc-run: bad interpreter: No such file or directory

I get this error whenever I try to start dhcpcd with sv /etc/runit/

And for sndiod I get this doing the same guide,

warning: sndiod: unable to open supervise/ok: file does not exist

Although rather ironically, If I type sndiod or dhcpcd into root, it works just fine.

Maybe its an FHS issue or possibly, I am screwing up? I am not sure. Feedback is welcome.

This is what I did:

=⇒ Add a service:

ln -s /etc/sv/<service> /var/service
==> Start/stop/restart a service:
sv <start/stop/restart> <service>

more or less, I used this guide.

Some forum display errors:

Cannot mix incompatible Qt library (version 0×50800) with this library (version 0×50904)

These two packages are directly affected by an older qt5...

Could you update all the qt packages to the LTS version available?

There are issues with the current sndio-package as it seems not possible to get this to work with ALSA.

The actual behavior is to create mount points if mountpoint exits with exit status 1, however it may also exit with code 32 and thus creating a real mess:

$ sudo chroot-nspawn

mount: /sys/fs/cgroup: mount point does not exist.

mount: /sys/fs/cgroup/freezer: mount point does not exist.
mount: /sys/fs/cgroup/memory: mount point does not exist.
mount: /sys/fs/cgroup/pids: mount point does not exist.

So I created a patch to fix this.

P.S.: although I can git clone the repo with ssh access, whenever I do a push I get:

error: remote unpack failed: unable to create temporary object directory
To ssh://git.hyperbola.info:51100/~git/software/chroot-nspawn.git

error: failed to push some refs to 'ssh://git.hyperbola.info:51100/~git/software/chroot-nspawn.git'

As proposed in a separate thread (https://forums.hyperbola.info/viewtopic.php?id=573): The navigation-bar needs a rework when accessing the website about the onion-protocol.

I don’t know if this is the best place for this, but I get stuck on the hardening the grub guide from libreboot,

https://libreboot.org/docs/gnulinux/grub_hardening.html

I wondered if there is anything different that needs to be done to get this part done:

gpg –homedir keys –detach-sign my.initramfs
gpg –homedir keys –detach-sign my.kernel
gpg –homedir keys –detach-sign libreboot_grub.cfg
gpg –homedir keys –detach-sign my.grubtest.cfg

it gives me a bunch of weird errors

Remove “cinepaint” package since it’s unmaintained and unsupportable. Also, it doesn’t contains any file format support in the latest version (previous version supported multiple file formats).

I suggest use Krita (or Gimp 2.10) to edit 16bit and 32bit file formats or convert with imagemagick/graphicsmagick.

Hi André, you could make an init for the searx search engine, it happens that
I want to launch it from local to avoid being in searx.me or

The Knock patches for linux-libre maintained by you at https://git.hyperbola.info:50100/kernels/knock.git/ have support up to linux-libre 4.13 only (and I think it didn’t work for it when I tried it, compilation failed) but from all of those supported versions, the newest maintained generation by the upstream is 4.9.x

However, since newer kernel generations might require reprogramming the patch, I want to request it only for the latest LTS generation which is 4.14. As you know, LTS software are supported for a long time, so it’s worth to make it for linux-libre 4.14.x

This might not be really important for Hyperbola in the short term, but you are the maintainers of the TCP Stealth implementation for Linux-libre and I and maybe other people would like to use it in their projects for newer versions.

Plus, it would be great since while 4.9 kernels can use the GRSec+Knock combination like linux-libre-lts-unofficial-grsec-knock, with support for 4.14 anyone would be able to use a combination of newer patches such as Linux-hardened+Knock (Linux-hardened supports 4.14 and 4.15 as of now) which is what I’d like to do.

Hi guys, I have ever run into a Brother brand printer model DCPT500W[0], and I have seen that the source code for the drivers under GPLv3 license is available.

I also see that there is a file brother_dcpt500w_printer_en.ppd, which is important for cups, which is why it may be necessary to integrate it into the cups, as long as the drivers are Libre.

Hello,

I recently acquired a T400 Thinkpad with 1440×900 panel.
On this T400, I installed Hyperbola, just like on my x200 Thinkpad with 1280×800 panel.

Both Thinkpad are running the same Hyperbola installation :

Full disk encryption (with Libreboot) so both Thinkpad are using early KMS (MODULES=”i915” in /etc/mkinitcpio.conf)
Same kernel : linux-libre-lts (4.9.99 at the moment I’m writing this message)
video driver : modesetting
DE : xfce4 with xfwm4

On the Thinkpad x200, everything works great, no issue to report.

On the T400 though, the linux-libre-lts kernel, I’m getting random display freezes, when it happens, this message appears in dmesg :

hpd interrupt storm detected on connector hdmi-a-1

And the display (and sound) freezes for 10 seconds (sometimes more !)

As Hyperbola proposes linux-libre-lts kernel only, I installed latest linux-libre-lts (4.14.40) and linux-libre (4.16.8) from Parabola GNU/Linux repo.

Results :

With 4.14.40 : Same issue as with 4.9.99 kernel from Hyperbola repo.
With 4.16.8 : Issue is not present ! No more freeze !

I’m not sure how to proceed though. Would you be kind enough helping me to find which commit in i915 driver improved the situation ? If we find it, maybe it could be added as a patch to 4.9.x kernel series.
Or maybe it is something else.. I don’t have much experience, I can provide logs if needed.

Thanks for your help

I have installed Hyperbola on two laptops. And I have noticed that after running sway and exiting out of sway, GNU emacs crushers on console. It is easy to repeat it:

1. Run sway
2. Exit sway or killall sway
3. Try running emacs on console, there will be crush
4. log out, log in, and emacs will work on console again

Yet it should not crush.
