f08df373a3 By default, when a process in jail calls getfsstat(), only return the
data for the file system on which the jail's root vnode is located.
Previous behavior (show data for all mountpoints) can be restored
by setting security.jail.getfsstatroot_only to 0.  Note: this also
has the effect of hiding other mounts inside a jail, such as /dev,
/tmp, and /proc, but errs on the side of leaking less information.

d08c5d0b9b Remove the check which used to protect us against make_dev() being
called until DEVFS had a chance to initialize.  Since DEVFS is mandatory
and things over in that department coincidentally works from without
any initialization now, this is safe.

84d98bf699 - Correct a long-standing race condition in vm_page_try_to_cache() that
could result in a panic "vm_page_cache: caching a dirty page, ...":
   Access to the page must be restricted or removed before calling
   vm_page_cache().  This race condition is identical in nature to that
   which was addressed by vm_pageout.c's revision 1.251.
 - Simplify the code surrounding the fix to this same race condition
   in vm_pageout.c's revision 1.251.  There should be no behavioral
   change.  Reviewed by: tegge

d3e1c2411e Fix hw.acpi.os_name by renaming it to hw.acpi.osname. The "_name" suffix
is reserved by the loader, and thus any tunable name with that suffix will
be silently discarded.

Document this in the header and man page so that other developers do not
develop so many bumps on the head after banging it against the wall.

1203f5be25 Fixed a misplaced ifdef that prevented npx.c building without "device isa"
ISA.  npx has few isa dependencies, but it does unconditional outb()'s to
the isa bus in the !SMP case, and it attaches to isa if "device isa" is
configured in order to support PNP-ISA.  The ifdef for the latter was
misplaced.

e7a4845084 Fixed longstanding brokenness of inode updates. The waitfor flag was
dishonored in rev.1.1 by commenting out the code that honored it.  This
gave the worst disadvantages of async mounts in an uncontrollable way.

Honoring the flag costs about 50% in real time in worst cases on a new
but not very fast ATA drive with write caching (probably more on drives
without write caching).  The old misbehavior can be recovered using
async mounts after implementing them in mount_ext2fs(8) (just put the
MNT_ASYNC flag in mount_ext2fs's table of supported options like it
is in mount's table).

1cfd4b5326 Initial import of RFC 2385 (TCP-MD5) digest support.
This is the first of two commits; bringing in the kernel support first.
This can be enabled by compiling a kernel with options TCP_SIGNATURE
and FAST_IPSEC.

For the uninitiated, this is a TCP option which provides for a means of
authenticating TCP sessions which came into being before IPSEC. It is
still relevant today, however, as it is used by many commercial router
vendors, particularly with BGP, and as such has become a requirement for
interconnect at many major Internet points of presence.

Several parts of the TCP and IP headers, including the segment payload,
are digested with MD5, including a shared secret. The PF_KEY interface
is used to manage the secrets using security associations in the SADB.

There is a limitation here in that as there is no way to map a TCP flow
per-port back to an SPI without polluting tcpcb or using the SPD; the
code to do the latter is unstable at this time. Therefore this code only
supports per-host keying granularity.

Whilst FAST_IPSEC is mutually exclusive with KAME IPSEC (and thus IPv6),
TCP_SIGNATURE applies only to IPv4. For the vast majority of prospective
users of this feature, this will not pose any problem.

This implementation is output-only; that is, the option is honoured when
responding to a host initiating a TCP session, but no effort is made
[yet] to authenticate inbound traffic. This is, however, sufficient to
interwork with Cisco equipment.

Tested with a Cisco 2501 running IOS 12.0(27), and Quagga 0.96.4 with
local patches. Patches for tcpdump to validate TCP-MD5 sessions are also
available from me upon request.

b4484bf031 Fixes problems that occurred when a file was removed and a directory
created with the same name, and vice versa:
- Immediately recycle vnodes of files & directories that have been deleted
or renamed.
- When looking an entry in the VFS name cache or smbfs's private
cache, make sure the vnode type is consistent with the type of file
the server thinks it is, and re-create the vnode if it isn't.

The alternative to this is to recycle vnodes unconditionally when their
use count drops to 0, but this would make all the caching we do
mostly useless.

b49d824e8b Add the SF_NODISKIO flag to sendfile. This flag causes sendfile to be
mindful of blocking on disk I/O and instead return EBUSY when such
blocking would occur.

Results from the DeBox project indicate that blocking on disk I/O
can slow the performance of a kqueue/poll based webserver.  Using
a flag such as SF_NODISKIO and throwing connections that would block
to helper processes/threads helped increase performance.

Currently, only the Flash webserver uses this flag, although it could
probably be applied to thttpd with relative ease.

4102d44b77 If a command has to be deferred because there are no more resources for it
on the card, unmap it first.  This allows it to be picked up properly when
the queue gets kicked again.  This was the root problem for the lost command
(i.e. stuck in getblk/vinvalb) problem.  While here, panic if commands don't
map correctly instead of just silently ignoring the problem and dropping
command.  Also slow down the dynamic allocation of new commands.

It should be safe to go back into the aac waters.  Thanks to everyone who
suffered through this and provided good feedback.

9ec5585585 Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772
802.11b chipset work. This chip is present on the SMC2602W version 3
NIC, which is what was used for testing. This driver creates kernel
threads (12 of them!) for various purposes, and required the following
routines:

PsCreateSystemThread()
PsTerminateSystemThread()
KeInitializeEvent()
KeSetEvent()
KeResetEvent()
KeInitializeMutex()
KeReleaseMutex()
KeWaitForSingleObject()
KeWaitForMultipleObjects()
IoGetDeviceProperty()

and several more. Also, this driver abuses the fact that NDIS events
and timers are actually Windows events and timers, and uses NDIS events
with KeWaitForSingleObject(). The NDIS event routines have been rewritten
to interface with the ntoskrnl module. Many routines with incorrect
prototypes have been cleaned up.

Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem())
which block on events, and this interferes with the operation of
NdisMAllocateSharedMemoryAsync(), which was also being put on the
NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync()
is now performed in the NDIS SWI thread instead.

There's still room for some cleanups here, and I really should implement
KeInitializeTimer() and friends.

8f6a5435e7 Reduce AAC_MAX_FIBS to work around some yet-unidentified bugs in the
handling of resources shortages.  The driver is now so fast that it can
completely fill all 512 slots on the card, but for some reason only 511
slots are being allocated.  Anything that tries to go into the 512th
slot gets silently lost.   Both bugs need to be fixed at a later date,
but this should fix the reports of hangs in getblk and vinvalb.

91d5354a2c Locking for the per-process resource limits structure.
- struct plimit includes a mutex to protect a reference count.  The plimit
  structure is treated similarly to struct ucred in that is is always copy
  on write, so having a reference to a structure is sufficient to read from
  it without needing a further lock.
- The proc lock protects the p_limit pointer and must be held while reading
  limits from a process to keep the limit structure from changing out from
  under you while reading from it.
- Various global limits that are ints are not protected by a lock since
  int writes are atomic on all the archs we support and thus a lock
  wouldn't buy us anything.
- All accesses to individual resource limits from a process are abstracted
  behind a simple lim_rlimit(), lim_max(), and lim_cur() API that return
  either an rlimit, or the current or max individual limit of the specified
  resource from a process.
- dosetrlimit() was renamed to kern_setrlimit() to match existing style of
  other similar syscall helper functions.
- The alpha OSF/1 compat layer no longer calls getrlimit() and setrlimit()
  (it didn't used the stackgap when it should have) but uses lim_rlimit()
  and kern_setrlimit() instead.
- The svr4 compat no longer uses the stackgap for resource limits calls,
  but uses lim_rlimit() and kern_setrlimit() instead.
- The ibcs2 compat no longer uses the stackgap for resource limits.  It
  also no longer uses the stackgap for accessing sysctl's for the
  ibcs2_sysconf() syscall but uses kernel_sysctl() instead.  As a result,
  ibcs2_sysconf() no longer needs Giant.
- The p_rlimit macro no longer exists.

4164174aff aic79xx.c:
aic79xx.seq:
	Convert the COMPLETE_DMA_SCB list to an "stailq".  This allows us to
	safely keep the SCB that is currently being DMA'ed back the host on
	the head of the list while processing completions off of the bus.  The
	newly completed SCBs are appended to the tail of the queue.   In the
	past, we just dequeued the SCB that was in flight from the list, but
	this could result in a lost completion should the host perform certain
	types of error recovery that must cancel all in-flight SCB DMA operations.

	Switch from using a 16bit completion entry, holding just the tag and the
	completion valid bit, to a 64bit completion entry that also contains a
	"status packet valid" indicator.  This solves two problems:
	  o The SCB DMA engine on at least Rev B. silicon does not properly deal
	    with a PCI disconnect that occurs at a non-64bit aligned offset in the
	    chips "source buffer".  When the transfer is resumed, the DMA engine
	    continues at the correct offset, but may wrap to the head of the buffer
	    causing duplicate completions to be reported to the host.  By using a
	    completion buffer in host memory that is 64bit aligned and using 64bit
	    completion entries, such disconnects should only occur at aligned addresses.
	    This assumes that the host bridge will only disconnect on cache-line
	    boundaries and that cache-lines are multpiles of 64bits.

	  o By embedding the status information in the completion entry we can avoid
	    an extra memory reference to the HSCB for commands that complete without
	    error.

	Use the comparison of a "host freeze count" and a "sequencer freeze count"
	to allow the host to process most SCBs that complete with non-zero status
	without having to clear critical sections.  Instead the host can just pause the
	sequencer, performs any necessary cleanup in the waiting for selection list,
	increments its freeze count on the controller, and unpauses.  This is only
	possible because the sequencer defers completions of SCBs with bad status
	until after all pending selections have completed.  The sequencer then avoids
	referencing any data structures the host may touch during completion of the
	SCB until the freeze counts match.

aic79xx.c:
	Change the strategy for allocating our sentinal HSCB for the QINFIFO.  In
	the past, this allocation was tacked onto the QOUTFIFO allocation.  Now that
	the qoutfifo has grown to accomodate larger completion entries, the old
	approach will result in a 64byte allocation that costs an extra page of
	coherent memory.  We now do this extra allocation via ahd_alloc_scbs()
	where the "unused space" can be used to allocate "normal" HSCBs.

	In our packetized busfree handler, use the ENSELO bit to differentiate
	between packetized and non-packetized unexpected busfree events that
	occur just after selection, but before the sequencer has had the oportunity
	to service the selection.

	When cleaning out the waiting for selection list, use the SCSI mode
	instead of the command channel mode.  The SCB pointer in the command
	channel mode may be referenced by the SCB dma engine even while the
	sequencer is paused, whereas the SCSI mode SCB pointer is only accessed
	by the sequencer.

	Print the "complete on qfreeze" sequencer SCB completion list in
	ahd_dump_card_state().  This list holds all SCB completions that are deferred
	until a pending select-out qfreeze event has taken effect.

aic79xx.h:
	Add definitions and structures to handle the new SCB completion scheme.

	Add a controller flag that indicates if the controller is in HostRAID
	mode.

aic79xx.reg:
	Remove macros used for toggling from one data fifo mode to the other.
	They have not been in use for some time.

	Add scratch ram fields for our new qfreeze count scheme, converting
	the complete dma list into an "stailq", and providing for the "complete
	on qfreeze" SCB completion list.  Some other fields were moved to retain
	proper field alignment (alignment >= field size in bytes).

aic79xx.seq:
	Add code to our idle loop to:
	  o Process deferred completions once a qfreeze event has taken full
	    effect.
	  o Thaw the queue once the sequencer and host qfreeze counts match.

	Generate 64bit completion entries passing the SCB_SGPTR field as the
	"good status" indicator.  The first bit in this field is only set if
	we have a valid status packet to send to the host.

	Convert the COMPLETE_DMA_SCB list to an "stailq".

	When using "setjmp" to register an idle loop handler, do not combine
	the "ret" with the block move to pop the stack address in the same
	instruction.  At least on the A, this results in a return to the setjmp
	caller, not to the new address at the top of the stack.  Since we want
	the latter (we want the newly registered handler to only be invoked from
	the idle loop), we must use a separate ret instruction.

	Add a few missing critical sections.

	Close a race condition that can occur on Rev A. silicon.  If both FIFOs
	happen to be allocated before the sequencer has a chance to service the
	FIFO that was allocated first, we must take special care to service the
	FIFO that is not active on the SCSI bus first.  This guarantees that a
	FIFO will be freed to handle any snapshot requests for the FIFO that is
	still on the bus.  Chosing the incorrect FIFO will result in deadlock.

	Update comments.

aic79xx_inline.h
	Correct the offset calculation for the syncing of our qoutfifo.

	Update ahd_check_cmdcmpltqueues() for the larger completion entries.

aic79xx_pci.c:
	Attach to HostRAID controllers by default.  In the future I may add a
	sysctl to modify the behavior, but since FreeBSD does not have any
	HostRAID drivers, failing to attach just results in more email and
	bug reports for the author.

0ee6dbd789 Remove pmap_pvo_allocf zone alloc function. It was a way of
using the direct-mapping of physmem to force PTE data structures
to be physically addressable so the interrupt-time real-mode
DSI trap handler could perform PTE spills. However, the memory
may have been > 256Mb, which would have caused a BAT spill and
double-interrupt.

The new trap code no longer handles PTE spills, so the requirement
that these pages be direct-mapped no longer applies. The irony is
UMA_MD_SMALL_ALLOC will return direct mappings for these structs :-)

- Comment on the thread/process selection and locking.

- Correct handling of "running"/"runnable" states, avoid "unknown"

  a misunderstanding of the more complex state machine / inhibitors
  behavior of KSE.

- Do perform ttyinfo() printing on KSE (P_SA) processes, it seems

b783c5e972 Correct/improve the implementation of NdisMAllocateSharedMemoryAsync().
Since we have a worker thread now, we can actually do the allocation
asynchronously in that thread's context. Also, we need to return a
status value: if we're unable to queue up the async allocation, we
return NDIS_STATUS_FAILURE, otherwise we return NDIS_STATUS_PENDING
to indicate the allocation has been queued and will occur later.

This replaces the kludge where we just invoked the callback routine
right away in the current context.

36c19a572a Add the kernel side of network interface renaming support.
The basic process is to send a routing socket announcement that the
interface has departed, change if_xname, update the sockaddr_dl
associated with the interface, and announce the arrival of the interface
on the routing socket.

As part of this change, ifunit() is greatly simplified by testing
if_xname directly.  if_clone_destroy() now uses if_dname to look up the
cloner for the interface and if_dunit to identify the unit number.

cea179a3fe Implement support for single packet sends. The Intel Centrino driver
that Asus provides on its CDs has both a MiniportSend() routine
and a MiniportSendPackets() function. The Microsoft NDIS docs say
that if a driver has both, only the MiniportSendPackets() routine
will be used. Although I think I implemented the support correctly,
calling the MiniportSend() routine seems to result in no packets going
out on the air, even though no error status is returned. The
MiniportSendPackets() function does work though, so at least in
this case it doesn't matter.

In if_ndis.c:ndis_getstate_80211(), if ndis_get_assoc() returns
an error, don't bother trying to obtain any other state since the
calls may fail, or worse cause the underlying driver to crash.

(The above two changes make the Asus-supplied Centrino work.)

Also, when calling the OID_802_11_CONFIGURATION OID, remember
to initialize the structure lengths correctly.

ab2bf9ff6a Removed bogus checks that (PCPU_GET(curpcb) != NULL). Rev.1.586 of
machdep.c fixed the missing early initialization of curpcb, so curpcb
is now always set together with curthread and it cannot be NULL except
before the IDT has been set up (so trap() is unreachable) or after a
memory error.  In any case, it was often used without checking.

curcpb shouldn't exist anyway.  It doesn't exist for most non-i386 arches.
It just caches curthread->td_pcb in a global.  This was a better idea
before it was per-cpu.  trap() and some other places can get at it more
efficiently using td->td_pcb instead of PCPU_GET(curpcb).  The main
exception is support.s which mostly wants only curpcb->pcb_onfault.

2. Unprivileged root was able to unmount file systems mounted by
   privileged root (execpt /).
3. User from inside a jail was able to mount file system when
   sysctl vfs.usermount was set to 1.
4. User was able to mount file system when vfs.usermount was set to 1
   (that's ok) and unmount it even if vfs.usermount was equal to 0
   (that's not correct).

Possibility from point 1 was reported by: Dariusz Kowalski <darek@76.pl>

Only a part of this fix will be MFC'ed (if approved).

322141f1e2 If the temperature is at _HOT or _CRT for 3 sequential readings, shutdown
the system.  Also, decrease the poll interval to 10 seconds from 30
seconds.  This is needed because some systems will report an invalid high
temperature for one poll cycle.  It is suspected this is due to the
embedded controller timing out.  A typical value is 138C for one cycle on a
system that is otherwise 65C.  This prevents the system from prematurely
shutting down after one invalid reading.  It will still shut down after 30
seconds of high temperature, which is the same as previous default
behavior.

This apparently was what broke the boot with some devices (liteon).

Somehow the bridge on there shows up with another PCI id than
it does on x86, no idea why...

fe5efaede8 - Make sure the apic is idle before sending an IPI. This is required on
non-X-APIC machines.  Previously this was only done in the
   DETECT_DEADLOCK case when really it is needed in all cases.
