Editing / Adding Point-to-Point Devices crashes system

[tokade]

Hi all,

while trying to identify the reason for my frozen system (https://forum.opnsense.org/index.php?topic=15354.0), I found another problem on my system running:

OPNsense 19.7.8-amd64
FreeBSD 11.2-RELEASE-p16-HBSD
OpenSSL 1.0.2t 10 Sep 2019

For my WAN connection I use the configuration type PPPoE which works fine. But when I try to edit (Interfaces -> Point-to-Point -> Devices) the existing device pppoe0 my system crashes. Same when I try to add a new device. After the reboot, I found a crash report in the GUI, which I sent via the  GUI.

In the case of editing the existing device, I found this information in a open ssh session:

Code Select Expand

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address   = 0x0
fault code              = supervisor read data, page not present

processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 89259 (sysctl)

Couldn't find anything similar in the forum.

Kind regards and merry XMas

Your problem is still in discussion, see here: CRASH in 19.1.8 when PPPOE refreshes. It seems to be a kernel bug in the netgraph subsystem.

Hi,

thx for your hint to the other thread. So I'm not the only one...

I can't reproduce the crash with the "disconnect/connect" buttons, only with edit or add point-to-point device. The nightly freezes might have the same reason. This morning I could connect to the VNC console where I found lots of messages: xn_txeof: WARNING: response is -1!

No chance to login and only destroying the domU helped again.

Will post on the other tread...

Kind regards
Torsten
