Hi,

Hi - sorry, seen too late.

Are we expecting that this will fix the crash?

Good question. I would says: yes, but you'll never know. Software is evil...

Besides, not everyone ran into this error. But it seems that both fixed and dhcp addresses on red0 are affected in some way.

For now, Arne reverted 'next' back to 'dhcpcd 7.2.3' (https://git.ipfire.org/?p=ipfire-2.x.git;a=shortlog;h=refs/heads/next).

In the meantime, Roy Marples is working on SEGVs, (udp-)checksum failures and core dumps with 8.x.x (https://roy.marples.name/archives/dhcpcd-discuss/). Doesn't sound good, but never happened here. I never saw that much noise on that list.

Do we even have a ticket for that?

Not yet. Right now, discussion is taking place in the forum (https://forum.ipfire.org/viewtopic.php?f=27&t=23455).

At the moment I'm running '8.1.1' on Core136/32bit and as with the other 8.x.x-versions do have no problems.

Best, Matthias

Best, -Michael

Hi,

'dhcpcd 8.1.1' is out.

=> https://roy.marples.name/archives/dhcpcd-discuss/0002641.html

"dhcpcd-8.1.1 has been released with the following changes:

• IPv6: Fix a potential crash when udevs marks an interface ready.
• Linux: compat shim added for setproctitle(3).
• arc4random: fixed UB in compat shim.
• DHCP: Fix fallout from dhcpcd-8.1.0 for checksum calculation.

The last fix involved a lot a people, quite a few different fixes and played havoc with gcc-9.2 but should now be resolved."

I'm working on it.

Best, Matthias
