# DF-3381 decisive run (guest DragonFly 6.5-DEVELOPMENT X86_64_GENERIC, INVARIANTS)
# command (via ssh as root): /root/poc/t3381
# The ssh session died when the kernel panicked mid-run (local 120s timeout,
# guest went down); stdout captured before the panic:
[+] BIOCSBLEN -> 32
(panic occurred in the setuid(nobody) child after BIOCSETIF(lo0) + 1st
 loopback UDP packet; child's further prints never reached the dead pipe)
# serial console (see panic.txt):
panic: bpf_mcopy
