bf8b583320 Setting PG_REFERENCED on a page at the end of vm_fault() is redundant since
the page table entry's accessed bit is either preset by the immediately
preceding call to pmap_enter() or by hardware (or software) upon return
from vm_fault() when the faulting access is restarted.

e3ebeca68e Change vm_object_madvise() so that it checks whether the page is invalid
or unmanaged before acquiring the page queues lock.  Neither of these
tests require that lock.  Moreover, a better way of testing if the page
is unmanaged is to test the type of vm object.  This avoids a pointless
vm_page_lookup().

c7fd54ae5a Enhance the historic behaviour of raw sockets and jails in a way
that we allow all possible jail IPs as source address rather than
forcing the "primary". While IPv6 naturally has source address
selection, for legacy IP we do not go through the pain in case
IP_HDRINCL was not set. People should bind(2) for that.

This will, for example, allow ping(|6) -S to work correctly for
non-primary addresses.

bba9d9c06c It seems ale(4) controllers do not like to see TCP payload in the
first descriptor in TSO case. Otherwise controller can generate bad
frames during TSO. To address it, make sure to pull up ethernet +
IP + TCP header with options in first buffer. Also ensure the
buffer length of the first descriptor for TSO covers entire ethernet
+ IP + TCP with options and setup additional Tx descriptor if the
first buffer includes TCP payload.

bf49d6a9f9 - Rework the underlying ALQ storage to be a circular buffer, which amongst other
things allows variable length messages to be easily supported.

- Extend KPI with alq_writen() and alq_getn() to support variable length
  messages, which is enabled at ALQ creation time depending on the
  arguments passed to alq_open(). Also add variants of alq_open() and
  alq_post() that accept a flags argument. The KPI is still fully
  backwards compatible and shouldn't require any change in ALQ consumers
  unless they wish to utilise the new features.

- Introduce the ALQ_NOACTIVATE and ALQ_ORDERED flags to allow ALQ consumers
  to have more control over IO scheduling and resource acquisition
  respectively.

- Strengthen invariants checking.

- Document ALQ changes in ALQ(9) man page.

019a1d16ba Clearing a page table entry's accessed bit (PG_A) and setting the
page's PG_REFERENCED flag in pmap_protect() can't really be justified.
In contrast to pmap_remove() or pmap_remove_all(), the mapping is not
being destroyed, so the notion that the page was accessed is not lost.
Moreover, clearing the page table entry's accessed bit and setting the
page's PG_REFERENCED flag can throw off the page daemon's activity
count calculation.  Finally, in my tests, I found that 15% of the
atomic memory operations being performed by pmap_protect() were only
to clear PG_A, and not change protection.  This could, by itself, be
fixed, but I don't see the point given the above argument.

Remove a comment from pmap_protect_pde() that is no longer meaningful
after the above change.

2934027caa An NFSv4 server will reply NFSERR_GRACE for non-recovery RPCs
during the grace period after startup. This grace period must
be at least the lease duration, which is typically 1-2 minutes.
It seems prudent for the experimental NFS client to wait a few
seconds before retrying such an RPC, so that the server isn't
flooded with non-recovery RPCs during recovery. This patch adds
an argument to nfs_catnap() to implement a 5 second delay
for this case.

0a905b1db9 Resurrect pmap_is_referenced() and use it in mincore(). Essentially,
pmap_ts_referenced() is not always appropriate for checking whether or
not pages have been referenced because it clears any reference bits
that it encounters.  For example, in mincore(), clearing the reference
bits has two negative consequences.  First, it throws off the activity
count calculations performed by the page daemon.  Specifically, a page
on which mincore() has called pmap_ts_referenced() looks less active
to the page daemon than it should.  Consequently, the page could be
deactivated prematurely by the page daemon.  Arguably, this problem
could be fixed by having mincore() duplicate the activity count
calculation on the page.  However, there is a second problem for which
that is not a solution.  In order to clear a reference on a 4KB page,
it may be necessary to demote a 2/4MB page mapping.  Thus, a mincore()
by one process can have the side effect of demoting a superpage
mapping within another process!

31257c4567 Change usb devd events from fake attach to a notify. The ugen device is not a
proper device_t so it faked the devctl event to appear like one, this is now a
notify which allows more information to be passed.

We notify for both the device attach/detach and for each usb interface. A devd
rule can now match on the interface properties, including composite devices
which may have a uvideo interface and also usound and possibly uhid too.

An example to match a umass device with a scsi subclass and BBB protocol would be

notify 100 {
	match "system"          "USB";
	match "subsystem"       "INTERFACE";
	match "type"            "ATTACH";
	match "intclass"        "0x08";
	match "intsubclass"     "0x06";
	match "intprotocol"     "0x50";
	action ...
};

The old attach devctl event has been retained for the moment to make merging to
8.1 easier. This was never compatible with 7.x or earlier due to the ugen regex
change needed.

fca97c8d7a Fix a deadlock in the shutdown code:
When performing a smp_rendezvous() or more likely, on amd64 and i386,
a smp_tlb_shootdown() the caller will end up with the smp_ipi_mtx
spinlock held, busy-waiting for other CPUs to acknowledge the operation.
As long as CPUs are suspended (via cpu_reset()) between the active mask
read and IPI sending there can be a deadlock where the caller will wait
forever for a dead CPU to acknowledge the operation.
Please note that on CPU0 that is going to be someway heavier because of
the spinlocks being disabled earlier than quitting the machine.

Fix this bug by calling cpu_reset() with the smp_ipi_mtx held.
Note that it is very likely that a saner offline/online CPUs mechanism
will help heavilly in fixing similar cases as it is likely more bugs
of this type may arise in the future.

o) Reduce diffs between various bits of TLB refill code in exception.S and

o) Don't doubly disable interrupts by moving zero to the status register,

o) Use CLEAR_STATUS to disable interrupts the first time.

o) Use kmem_alloc_nofault_space() with VMFS_TLB_ALIGNED_SPACE to allocate the
   kernel stack address on MIPS. [1]
o) Make pmap_align_tlb() on MIPS align addresses so that they do not start on
   an odd boundary within the TLB, so that they are suitable for insertion as
   wired entries and do not have to share a TLB entry with another mapping,
   assuming they are appropriately-sized.
o) Eliminate md_realstack now that the kstack will be appropriately-aligned on
   MIPS.

   alignment of the kstack address.

1 - Make the function that acquires a stateid for I/O operations

    out of date stateids.
2 - Only allow a recovery once every 1/2 of a lease duration, since
    the NFSv4 server must provide a recovery grace period of at
    least a lease duration. This should avoid recoveries caused
    by an out of date stateid that was acquired for an I/O op.

7075c32b12 In vm_object_backing_scan(), setting PG_REFERENCED on a page before
sleeping on that page is nonsensical.  Doing so reduces the likelihood
that the page daemon will reclaim the page before the thread waiting in
vm_object_backing_scan() is reawakened.  However, it does not guarantee
that the page is not reclaimed, so vm_object_backing_scan() restarts
after reawakening.  More importantly, this muddles the meaning of
PG_REFERENCED.  There is no reason to believe that the caller of
vm_object_backing_scan() is going to use (i.e., access) the contents of
the page.  There is especially no reason to believe that an access is
more likely because vm_object_backing_scan() had to sleep on the page.

58be1647f8 When an underlying ioctl(2) handler returns an error, our ioctl(2)
interface considers that it hits a fatal error, and will not copyout
the request structure back for _IOW and _IOWR ioctls, keeping them
untouched.

The previous implementation of the SIOCGIFDESCR ioctl intends to
feed the buffer length back to userland.  However, if we return
an error, the feedback would be defeated and ifconfig(8) would
trap into an infinite loop.

This commit changes SIOCGIFDESCR to set buffer field to NULL to
indicate the previous ENAMETOOLONG case.

04d9731c75 Add driver for Silicon Integrated Systems SiS190/191 Fast/Gigabit Ethernet.
This driver was written by Alexander Pohoyda and greatly enhanced
by Nikolay Denev. I don't have these hardwares but this driver was
tested by Nikolay Denev and xclin.

Because SiS didn't release data sheet for this controller, programming
information came from Linux driver and OpenSolaris. Unlike other open
source driver for SiS190/191, sge(4) takes full advantage of TX/RX
checksum offloading and does not require additional copy operation in
RX handler.
The controller seems to have advanced offloading features like VLAN
hardware tag insertion/stripping, TCP segmentation offload(TSO) as
well as jumbo frame support but these features are not available
yet. Special thanks to xclin <xclin<> cs dot nctu dot edu dot tw>
who sent fix for receiving VLAN oversized frames.

Only acquire locks for O_EXLOCK/O_SHLOCK if file type is still vnode,
since we allow for fcntl(2) to process with advisory locks for
DTYPE_VNODE only. Another reason is that all fo_close() routines need to
check and release locks otherwise.

For O_TRUNC, call fo_truncate() instead of truncating the vnode.

d7a91dc6bf Plug reference leaks in the link-layer code ("new-arp") that previously
prevented the link-layer entry from being freed.

In both in.c and in6.c (though that code path seems to be basically dead)
plug a reference leak in case of a pending callout being drained.

In if_ether.c consistently add a reference before resetting the callout
and in case we canceled a pending one remove the reference for that.
In the final case in arptimer, before freeing the expired entry, remove
the reference again and explicitly call callout_stop() to clear the active
flag.

In nd6.c:nd6_free() we are only ever called from the callout function and
thus need to remove the reference there as well before calling into
llentry_free().

In if_llatbl.c when freeing entire tables make sure that in case we cancel
a pending callout to remove the reference as well.
