kernel: double fault trap, code=0 (4)

Status: fixed on 2021/01/09 22:01
Reported-by: syzbot+a43ace363f1b663238f8@syzkaller.appspotmail.com
Fix commit: c11d76984715 Syzkaller has found a stack overflow in socket splicing. Broadcast packets were resent through simplex broadcast delivery and socket splicing. Although there is an M_LOOP check in somove(9), it did not take effect. if_input_local() cleared the M_BCAST and M_MCAST flags with m_resethdr(). As if_input_local() is used for broadcast and multicast delivery, it was a mistake to delete them. Keep the M_BCAST and M_MCAST mbuf flags when packets are reinjected into the network stack.
