after core update 136, dhcpcd stops running on red0

Post by cfusco » October 12th, 2019, 8:35 pm

Since I updated to core 136 in apparently a random way, the dhcpd stops running on the red interface. It has happened so far about one hour after the update, then again about one hour after I restarted the machine and again during the night. Now it is the second night.
This is my normal ifconfig output:

And this is after the red0 interface stops being properly configured (notice the absence of the ip address):

Re: after core update 136, dhcpd stops running on red0

Post by BeBiMa » October 12th, 2019, 9:04 pm

I've noticed a similiar behaviour.
After some random time dhcpcd stops with an "segfault error". The problem seems to be coupled to a change of the IP address on red0.

The mailing list of dhcpcd contains postings about an SEGV error. Version 8.1.0 should fix this issue ( according to the mail list ).

Thanks, I thought I was crazy! Would be possible to downgrade to the previous version of dhcpd, so that I do not have to reinstall core 135?

Hi,

Update to dhcpcd 8.1.0 is on GIT and on Patchwork.

Best,

No offence intended, but how does the presence of updates on patchwork or git resolve the problems encountered by current users of Core 136?

The problem is that core136 doesnt touch dhcpcd, in core135 is the same version. So I'm not understand whats going on here.

I will add the update to core137 and rebuild...

Hi,

@RedneckMother:
No problem, I don't feel offended. ;)
I haven't had this problem yet, but I can provide at least an update. If the SEGV is actually due to 'dhcpcd' perhaps only a downgrade may help.

@Arne:
After a quick look in the cited 'dhcpcd'-mailing list I found Re: [Security][Patch] SEGV in dhcpcd-8.0.4.

@BeBiMa:
Was that the mailing you meant?

So, if Roys patch for 8.0.4 didn't work as intended (Murphys Law!) it could be, that both 8.0.5 and 8.0.6 are still affected in some way. How knows?

That's why I pushed the 8.1.0-version as fast as possible - and to get the other developers informed.

Besides, 8.1.0 is running here with no seen problems and: it was ~1:10am here and time for bed... ;)

Best,
Matthias

Are you sure? According to the blog announcements 135 has 7.2.3 and 136 8.0.3

sorry. You are correct. Core136 updates from 7 to 8.03...

I have added 8.10 to core137 and built for testing... If this not work we will downgrade...

We even could get problems with 8.1.0. *sigh*

It's happening 2/3 times per day. Waiting for the fix and not really wanting to reinstall from scratch 135 and then do a restore of the backup settings, I though to write a simple script that restarts the server:

Code: Select all

#!/bin/sh
echo -e "-------------------------\n$(date)"  >> /root/log_script_workaround_dhcpd_bug.txt
dhcpcd -T red0 -t 2 &>> /root/log_script_workaround_dhcpd_bug.txt
I did put the script with execution privilege in /etc/fcron.hourly. The intent is that when I am away from my network, if it goes down it stays down at the most 1 hour. Since I do not know what I am doing, does anyone have any advice or criticism? Thanks.

Edit: it seems it's working as intended. For now I will use this work around until 137 is released with the fix.

The error "failed to renew DHCP, rebinding" accompanies each refresh.

Re: after core update 136, dhcpd stops running on red0

What's the story with this, is it a universal issue or only limited cases? I've held off upgrading one of my systems after I saw this thread. Should I wait for 137?
