HISTORY
The
fwohci device driver first appeared in
FreeBSD 5.0. It was added to
NetBSD
4.0.
AUTHORS
The
fwohci device driver was written by
Katsushi Kobayashi and
Hidetoshi
Shimokawa. It was added to
NetBSD 4.0 by
KIYOHARA Takashi.
BUGS
The driver allows physical access from any node on the bus by default. This
means that any devices on the bus can read and modify any memory space which
can be accessed by an IEEE 1394 OHCI chip. It is allowed mostly for
sbp(4) devices. This should be
changed to allow it only for specific devices. Anyway, IEEE1394 is a bus and
not expected to be connected with un-trustable devices because a node can
monitor all the traffic.
