Hi all, I am just wondering if there are patched kernel images for the Dirty COW exploit?

v4.8.3 has this fix. At the moment it's present only in our developing repository (beta.armbian.com). We will try to push an update out on default repo ASAP.

Looks like not all kernels were fixed, 3.4 and 3.10 may need adding this patch manually

3.4 and 3.14 need to be fixed, the rest is.

I see the patches are in the new release. Thanks, updated my Cubietruck.
 

I've seen the updates in the repo, but after an apt-get update and reboot my OpiPC doesn't boot.

I've built an image from the latest sources (Armbian_5.23_Orangepipc_Debian_jessie_4.8.3.img) but still no dice.

Reflashed the previous image (Armbian_5.21_Orangepipc_Debian_jessie_4.7.6.img), the one from which I tried to update at first and it booted successfully.

 

Does anybody else experiences this?

Armbian_5.23_Orangepipc_Debian_jessie_4.8.3.img

 

4.8.x seems to cause problems with H3 boards, see known problems section of 5.22 release: http://docs.armbian.com/Release_Changelog/

 

Kernel 4.x with H3 is still considered experimental. Since you use the build system why not trying out https://github.com/megous/linux/tree/orange-pi-4.9-hdmi  instead? It's just a single change here.

Thanks for the heads-up, I've checked the changelog, but failed to notice it. : /

This was my plan for tomorrow, guess I go ahead with it then.

4.9 works (somehow): http://sprunge.us/UVDS

Thanks for testing it out.

Now I definitely give it a spin tomorrow. Maybe the bug that causes the panic with containerized torrent client is fixed. But obviously it is a pretty niche use-case, so I won't hold my breath.

Does the opipc image with 4.9-hdmi  still builds for you?

 

Sure. The 'Device or resource busy' errors tell you to reboot your build host (at least that's what I do when that occurs, I also have a script running at login that starts to delete old OS images below 'output/images/' until 20 GB disk space are free again).

 

Your temper build fails also so please try to add ' EXTERNAL=no' to the compile.sh call.

@Drakoh

 

Looks like corrupted rootfs cache, so please delete everything in output/cache/rootfs too.

Could you please upload your image (or at least the 4.9 kernel) somewhere?

The build issue has been solved by a cleanup as you suggested with zador.blood.stained, but the 4.9 kernel just doesn't want to work for me.

I've build both the 4.9 and the 4.9-hdmi branch, tried with Armbian 5.21 and 5.23 but the boot always stops at this line:

<... everything is fine until here, no error, etc ...>

[  OK  ] Started LSB: Tune IDE hard disks.
<... after this point, it just hangs ...>

4.9 kernel currently crashes here for me too on some boards

@zador.blood.stained thanks for the fast feedback.
