July 29 amd64 snap. I had just tested something in a vm (not very
common for me) and did "halt -p" in the guest. Immediately afterwards
I hit this:
uvm_fault(0xfffffd84031d4ef0, 0x8, 0, 1) -> e
kernel: page fault trap, code=0
Stopped at filt_bpfrdetach+0x43: movq 0x8(%rax),%rax
>From ps /o it seems lldpd was involved - this would be using bpfs.
was running at startup. The bridge was created and vmd was started later after
boot (while lldpd was already running, if that matters).
If a step-by-step reproducer or more details are needed I'll try to figure
something out when I'm on a machine that is less annoying to fsck.
vm.conf like this,
: switch "uplink" {
: interface bridge0
: }
:
: vm "open" {
: disable
: owner sthen
: memory 1G
: interface { switch "uplink" }
: disk "/data/vmm/open.img"
: }
and lldpd just running with defaults (pkg_add lldpd, rcctl enable lldpd)
