FUSE filesystem must be patched to #include <perfuse.h> in the source
files that open /dev/fuse and perform the mount(2) system call. The
FUSE filesystem must be linked with -lperfuse.
libperfuse(3) implements the FUSE kernel interface, on which libfuse or
any FUSE filesystem that opens /dev/fuse directly can be used.
For now, an external daemon called perfused(8) is used. This may change
in the future.

Thus, use ACPI_DEBUG_PRINT() instead of ACPI_INFO() when a table is loaded
dynamically.

as we now have a global notify handler that can catch the debug information.)
our SCSIPI driver stack. Currently we pretend to be a single CD
controller with an optional host file as the image, but I guess
the sky's the limit.

check (today it was christos@' laptop), follow Linux and disable this rather
expensive sanity-check for the time being. A hypothesis about the cause of
the failures relates to the absence of cross-CPU coordination in the current
implementation.
will go backwards; K7 will not be supported already due doubts about
availability and reliability of ACPI during that era. Some unfortunate code
duplication is present (but not overly much). Thanks to cegger@ and jakllsch@
for patiently testing this.
- since the size is unsigned, don't check just that it is > 0, but limit
it to the MAXSSIZ
- if the stack size is reduced because of aslr, make sure we reduce the
actual allocation by the same size so that the size does not wrap around.
NB: Must be pulled up to 5.x!
from a callout, so delay was the only option (in those days). Then
the caller was converted to a thread, but left as a delay. It
still may block the scsipi completion thread processing (so I
seriously doubt this code path is executed very often on a live
system).
XXX: there's apparently some race condition which appears to trigger
if a broadcast arp arrives around the same time as the arpwhohas
is sent. This causes original packet to never be sent by the
arpwhohas requestor. If this rings a bell to someone, please let
me know.
- Designed to be fully MP-safe and highly efficient.
- Tables/IP sets (hash or red-black tree) for high performance lookups.
- Stateful filtering and Network Address Port Translation (NAPT).
Framework for application level gateways (ALGs).
- Packet inspection engine called n-code processor - inspired by BPF -
supporting generic RISC-like and specific CISC-like instructions for
common patterns (e.g. IPv4 address matching). See npf_ncode(9) manual.
- Convenient userland utility npfctl(8) with npf.conf(8).
NOTE: This is not yet a fully capable alternative to PF or IPFilter.
Further work (support for binat/rdr, return-rst/return-icmp, common ALGs,
state saving/restoring, logging, etc) is in progress.
Thanks a lot to Matt Thomas for various useful comments and code review.
