Adapt the mfsroot environment of sysinstall to the needs of the new dhclient.
This involves having passwd bits available so that seteuid("_dhcp") work,
and creating /var/empty so that chroot(_VAR_EMPTY) works. My gut feeling
is that the better solution is to make privsep and chroot optional in
dhclient, but this works well for now and is low-risk.
Adapt sysinstall to the new dhclient. This includes explicitely telling
it about the lease file location and not invoking it with the (non-existant)
'-r' option. Releasing leases works vastly different now, so this isn't
needed.

Validate if the value written into {FS,GS}.base is a canonical

Detailed Changes
================
mpt.c mpt_cam.c mpt_raid.c mpt_pci.c:
o Add support for personality modules. Each module exports
load, and unload module scope methods as well as probe, attach,
event, reset, shutdown, and detach per-device instance
methods
mpt.c mpt.h mpt_pci.c:
o The driver now associates a callback function (via an
index) with every transaction submitted to the controller.
This allows the main interrupt handler to absolve itself
of any knowledge of individual transaction/response types
by simply calling the callback function "registered" for
the transaction. We use a callback index instead of a
callback function pointer in each requests so we can
properly handle responses (e.g. event notifications)
that are not associated with a transaction. Personality
modules dynamically register their callbacks with the
driver core to receive the callback index to use for their
handlers.
o Move the interrupt handler into mpt.c. The ISR algorithm
is bus transport and OS independent and thus had no reason
to be in mpt_pci.c.
o Simplify configuration message reply handling by copying
reply frame data for the requester and storing completion
status in the original request structure.
o Add the mpt_complete_request_chain() helper method and use
it to implement reset handlers that must abort transactions.
o Keep track of all pending requests on the new
requests_pending_list in the softc.
o Add default handlers to mpt.c to handle generic event
notifications and controller reset activities. The event
handler code is largely the same as in the original driver.
The reset handler is new and terminates any pending transactions
with a status code indicating the controller needs to be
re-initialized.
o Add some endian support to the driver. A complete audit is
still required for this driver to have any hope of operating
in a big-endian environment.
o Use inttypes.h and __inline. Come closer to being style(9)
compliant.
o Remove extraneous use of typedefs.
o Convert request state from a strict enumeration to a series
of flags. This allows us to, for example, tag transactions
that have timed-out while retaining the state that the
transaction is still in-flight on the controller.
o Add mpt_wait_req() which allows a caller to poll or sleep
for the completion of a request. Use this to simplify
and factor code out from many initialization routines.
We also use this to sleep for task management request
completions in our CAM timeout handler.
mpt.c:
o Correct a bug in the event handler where request structures were
freed even if the request reply was marked as a continuation
reply. Continuation replies indicate that the controller still owns
the request and freeing these replies prematurely corrupted
controller state.
o Implement firmware upload and download. On controllers that do
not have dedicated NVRAM (as in the Sun v20/v40z), the firmware
image is downloaded to the controller by the system BIOS. This
image occupies precious controller RAM space until the host driver
fetches the image, reducing the number of concurrent I/Os the
controller can processes. The uploaded image is used to
re-program the controller during hard reset events since the
controller cannot fetch the firmware on its own. Implementing this
feature allows much higher queue depths when RAID volumes
are configured.
o Changed configuration page accessors to allow threads to sleep
rather than busy wait for completion.
o Removed hard coded data transfer sizes from configuration page
routines so that RAID configuration page processing is possible.
mpt_reg.h:
o Move controller register definitions into a separate file.
mpt.h:
o Re-arrange includes to allow inlined functions to be
defined in mpt.h.
o Add reply, event, and reset handler definitions.
o Add softc fields for handling timeout and controller
reset recovery.
mpt_cam.c:
o Move mpt_freebsd.c to mpt_cam.c. Move all core functionality,
such as event handling, into mpt.c leaving only CAM SCSI
support here.
o Revamp completion handler to provide correct CAM status for
all currently defined SCSI MPI message result codes.
o Register event and reset handlers with the MPT core. Modify
the event handler to notify CAM of bus reset events. The
controller reset handler will abort any transactions that
have timed out. All other pending CAM transactions are
correctly aborted by the core driver's reset handler.
o Allocate a single request up front to perform task management
operations. This guarantees that we can always perform a
TMF operation even when the controller is saturated with other
operations. The single request also serves as a perfect
mechanism of guaranteeing that only a single TMF is in flight
at a time - something that is required according to the MPT
Fusion documentation.
o Add a helper function for issuing task management requests
to the controller. This is used to abort individual requests
or perform a bus reset.
o Modify the CAM XPT_BUS_RESET ccb handler to wait for and
properly handle the status of the bus reset task management
frame used to reset the bus. The previous code assumed that
the reset request would always succeed.
o Add timeout recovery support. When a timeout occurs, the
timed-out request is added to a queue to be processed by
our recovery thread and the thread is woken up. The recovery
thread processes timed-out command serially, attempting first
to abort them and then falling back to a bus reset if an
abort fails.
o Add calls to mpt_reset() to reset the controller if any
handshake command, bus reset attempt or abort attempt
fails due to a timeout.
o Export a secondary "bus" to CAM that exposes all volume drive
members as pass-thru devices, allowing CAM to perform proper
speed negotiation to hidden devices.
o Add a CAM async event handler tracking the AC_FOUND_DEVICE event.
Use this to trigger calls to set the per-volume queue depth once
the volume is fully registered with CAM. This is required to avoid
hitting firmware limits on volume queue depth. Exceeding the
limit causes the firmware to hang.
mpt_cam.h:
o Add several helper functions for interfacing to CAM and
performing timeout recovery.
mpt_pci.c:
o Disable interrupts on the controller before registering and
enabling interrupt delivery to the OS. Otherwise we risk
receiving interrupts before the driver is ready to receive
them.
o Make use of compatibility macros that allow the driver to
be compiled under 4.x and 5.x.
mpt_raid.c:
o Add a per-controller instance RAID thread to perform settings
changes and query status (minimizes CPU busy wait loops).
o Use a shutdown handler to disable "Member Write Cache Enable"
(MWCE) setting for RAID arrays set to enable MWCE During Rebuild.
o Change reply handler function signature to allow handlers to defer
the deletion of reply frames. Use this to allow the event reply
handler to queue up events that need to be acked if no resources
are available to immediately ack an event. Queued events are
processed in mpt_free_request() where resources are freed. This
avoids a panic on resource shortage.
o Parse and print out RAID controller capabilities during driver probe.
o Define, allocate, and maintain RAID data structures for volumes,
hidden member physical disks and spare disks.
o Add dynamic sysctls for per-instance setting of the log level, array
resync rate, array member cache enable, and volume queue depth.
mpt_debug.c:
o Add mpt_lprt and mpt_lprtc for printing diagnostics conditioned on
a particular log level to aid in tracking down driver issues.
o Add mpt_decode_value() which parses the bits in an integer
value based on a parsing table (mask, value, name string, tuples).
mpilib/*:
o Update mpi library header files to latest distribution from LSI.

we ever want to implement breaking into OFW. Unfortunately there
doesn't seem to be a better way to achieve this as e.g. bypassing
the color map isn't supported by all Mach64 chips.
- Move invalidating the cache variables to machfb_set_mode() and
set the V_ADP_MODECHANGE flag. This causes machfb_set_mode() to

Change default key allocation method to do the right thing for
legacy parts (i.e. those that have 4 global key slots). We
blindly assign unicast keys to key slot 0. Devices that need
alternate allocation logic must override this method.
sys/sys/pmc.h, sys/dev/hwpmc/hwpmc_mod.c:
- Fix a bug affecting debug printfs.
- Move the 'stalled' flag from being in a bit in the
'pm_flags' field of a 'struct pmc' to a field of its own in the
same structure. This flag is updated from the NMI handler and
keeping it separate makes it easier to avoid races with other
parts of the code.
sys/dev/hwpmc/hwpmc_logging.c:
- Do arithmetic with 'uintptr_t' types rather that casting
to and from 'char *'.
Have the NMI handler call the C language trap() routine and directly
exit via 'doreti_exit'.
Since the NMI interrupt may be taken at any time, including when
the processor has masked external interrupts, it is not safe to
call ast() as is done for normal interrupts.
Some cleanups and tweaks to some of the atomic.h files in preparation for
further changes and fixes in the future:
- Use aliases via macros rather than duplicated inlines wherever possible.
- Move all the aliases to the bottom of these files and the inline
functions to the top.
- Add various comments.
- On alpha, drop atomic_{load_acq,store_rel}_{8,char,16,short}().
- On i386 and amd64, don't duplicate the extern declarations for functions
in the two non-inline cases (KLD_MODULE and compiler doesn't do inlines),
instead, consolidate those two cases.
- Some whitespace fixes.
Add missing locking to linux_connect() so that it can be marked MP safe:
- Conditionally grab Giant around the EISCONN hack at the end based on
debug.mpsafenet.
- Protect access to so_emuldata via SOCK_LOCK.
The nsegs parameter to bus_dmamap_load_mbuf_sg is not required to
be set to 0 on input. This caused a panic in an an MP test version
of the GEM driver from Marius, and from inspection of other PCI
drivers, the same problem would happen there.
Fix by explicitly setting to 0.
Add Farrallon EtherMac PC Card to the list of supported cards.
Fix XJack card description to reflect the actual model that we support
(I've never seen a CC-10BT and I've been looking).
List the specific chipsets supported.
Bump date.

Noticed that NetBSD's sm driver has the PSION GOLDCARD listed, so list
that since I can't test it directly. The driver also lists the EM1144
as being supported, but in reality it isn't. The EM1144-T,
{XJ,CC}{3288,3336} have the SMC chips in them, but aren't conformant MFC
cards, so they need their own driver.
Also, it does little harm to list the 8020BT, so remove #if 0.
Change communication protocol to be much more resistant on network
problems and to allow for much better performance.
Better performance is achieved by creating two connections between
ggatec and ggated one for sending the data and one for receiving it.
Every connection is handled by separeted thread, so there is no more
synchronous data flow (send and wait for response), now one threads
sends all requests and another receives the data.
Use two threads in ggatec(8):
- sendtd, which takes I/O requests from the kernel and sends them to the
ggated daemon on the other end;
- recvtd, which waits for ggated responses and forwards them to the kernel.
Use three threads in ggated(8):
- recvtd, which waits for I/O requests and puts them onto incoming queue;
- disktd, which takes requests from the incoming queue, does disk operations
and puts finished requests onto outgoing queue;
- sendtd, which takes finished requests from the outgoing queue and sends
responses back to ggatec.
Because there were major changes in communication protocol, there is no
backward compatibility, from now on, both client and server has to run
on 5.x or 6.x (or at least ggated should be from the same FreeBSD version
on which ggatec is running).
For Gbit networks some buffers need to be increased. I use those settings:
kern.ipc.maxsockbuf=16777216
net.inet.tcp.sendspace=8388608
net.inet.tcp.recvspace=8388608
and I use '-S 4194304 -R 4194304' options for both, ggatec and ggated.
ral_init() takes a struct ral_softc as parameter not a struct ifnet.
Fixes a panic that occured when setting the interface parameters while
the interface was associated.
Use implicit type cast for ->k_lock to fix compilation of ndis
as a part of the GENERIC kernel with INVARIANT* and WITNESS*
