lldpad crashes due to piling up of transient veth interfaces in lldpad.conf #3
Description
Hi All,
On my system, lldp keeps crashing with the following error :
kernel: [1590523.105977] lldpad[17922]: segfault at c68 ip 000055f3a7de9c6a sp 00007ffc816b37c0 error 6 in lldpad[55f3a7dad000+60000]
lldpad.service: main process exited, code=killed, status=11/SEGV
Unit lldpad.service entered failed state.
Version : lldpad-1.0.1-5.1.git036e314.el7.centos.x86_64
We create lots of veth pairs and delete them at certain intervals. I see all these transient interfaces in lldpad.conf, but they are not removed.
lldpad adds all interfaces to lldpad.conf, but they are not cleaned when the interfaces are deleted. If the interfaces are virtual ethernets that are transient, the interfaces are not removed. This causes the lldpad.conf to keep growing.
lldp scan this list for changes to all the listed interfaces. This is causing the lldp to crash. Has there been a fix for this in latest releases ?
Thanks,
Srijit
