Subject: Random XDP detachments
Date: Wed, 14 Jul 2021 21:45:07 +0000	[thread overview]
Message-ID: <VE1PR01MB563154CC7B9BBB5B750BF3A78A139@VE1PR01MB5631.eurprd01.prod.exchangelabs.com> (raw)

Hi, 


I'm encountering a scenario in which at random periods of time, XDP programs attached on all interfaces suddenly detach.
I have not found any relevant kernel logs during the 
times this happens, and I could not link this to any userspace process, 
especially since I only need to bpftool attach in order to reproduce this.
Is there something from the kernel side that can cause 
this to happen? The XDP programs have also been used successfully in the
 past with no problems.
The obvious solution of a reboot is unfortunately not a possibility at the moment.


Thanks, Marius-Cristian Baciu
