>Synopsis: a pflow interface panics the -current kernel
>Category: kernel
>Environment:
System : OpenBSD 6.0
Details : OpenBSD 6.0-current (GENERIC.MP) #159: Tue Jan 31
21:48:51 MST 2017
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
When I add a /etc/hostname.pflow0 to any system with the following
contents:
flowsrc [2001:db8:0:10::202] flowdst [2001:db8:0:10::352]:12345 pflowproto 5
The kernel panics on boot/ifconfig. Here is the backtrace information:
