Before r228267 the option was honored but the original content of
boot.config was not preserved.  I tried to fix that but missed the idea.
Now the proper way of doing things is taken from i386/boo2.
Also, a comment is added to explain this a little bit unobvious

When we receive an ICMP unreach need fragmentation datagram, we take
proposed MTU value from it and update the TCP host cache. Then
tcp_mss_update() is called on the corresponding tcpcb. It finds the
just allocated entry in the TCP host cache and updates MSS on the
tcpcb. And then we do a fast retransmit of what we have in the tcp
send buffer.

This sequence gets broken if the TCP host cache is exausted. In this
case allocation fails, and later called tcp_mss_update() finds nothing
in cache. The fast retransmit is done with not reduced MSS and is
immidiately replied by remote host with new ICMP datagrams and the
cycle repeats. This ping-pong can go up to wirespeed.

To fix this:
- tcp_mss_update() gets new parameter - mtuoffer, that is like
  offer, but needs to have min_protoh subtracted.
- tcp_mtudisc() as notification method renamed to tcp_mtudisc_notify().
- tcp_mtudisc() now accepts not a useless error argument, but proposed
  MTU value, that is passed to tcp_mss_update() as mtuoffer.

Turn on PREEMPTION by default. After fixing several bugs over time, the
last show-stopper keeping PREEMPTION from being usable on sparc64 should
have been dealt with in r230662.
At least on 2-way systems, PREEMPTION causes a little bit of a degradation
in worldstone performance. However, FreeBSD seems to have started building
up regressions in !PREEMPTION cases so sparc64 better should not be an
oddball in this regard.

- When interrupt is not requested for VM86 call, make a fake exit point and
push the address onto stack as we do for INTn emulation.  This avoids stack
underflow when we encounter RETF instruction in VM86 mode.  Lack of this
exit point actually caused page fault in VM86 mode with VESA module when we
resume from suspend state[1].
- Remove unnecessary CLI and STI instructions from BIOS interrupt emulation.
INTn and IRET must be able to emulate the flag correctly.

- Move pipe(2) implementation for Linuxulator from MD files to MI file,
sys/compat/linux/linux_file.c.  There is no MD code for this syscall at all.
- Correct an argument type for pipe() from l_ulong * to l_int *.  Probably

memory to clear contention bit, there is a race that other threads
can lock it and unlock it, then destroy it, so it should not write
data to the mutex memory if there isn't any waiter.
The new operation UMTX_OP_MUTEX_WAKE2 try to fix the problem. It
requires thread library to clear the lock word entirely, then
call the WAKE2 operation to check if there is any waiter in kernel,
and try to wake up a thread, if necessary, the contention bit is set again
by the operation. This also mitgates the chance that other threads find
the contention bit and try to enter kernel to compete with each other
to wake up sleeping thread, this is unnecessary. With this change, the
mutex owner is no longer holding the mutex until it reaches a point
where kernel umtx queue is locked, it releases the mutex as soon as
possible.
Performance is improved when the mutex is contensted heavily.  On Intel
i3-2310M, the runtime of a benchmark program is reduced from 26.87 seconds
to 2.39 seconds, it even is better than UMTX_OP_MUTEX_WAKE which is

Fixes to pf_route(), pf_route6().

These functions are very special, they may call into send side of IP
stack, for example they call ifp->if_output(), icmp_error(), icmp6_error(),
ip6_output(), and they also can perform route lookup. Even more, they
can call pf_test() or pf_test6() recursively! Hence, they need dropping
any pf(4) locks before.

Fortunately, pf_route() and pf_route6() are called only at the
very end of packet processing, so we can drop the pf(4) locks
with no need re-acquire them, thus:

o Drop locks in pf_route(), pf_route6() in all error cases.
o Drop locks in pf_route(), pf_route6() as soon as we get
  information from the state, or if there is no state, or
  if we don't need state.

More cleanups and fixes to pf_route():
- We don't need to check for m_len, pf_test() already did this.
- To do route lookup we don't need to allocate 'struct route'
  on stack, we can just have a sockaddr and rtentry pointer.
- We need rtentry for a quite short time, so it is better to
  avoid its unlocking and refcounting.
- In case if new interface (after routing rule applied) is
  a loopback one, then put M_SKIP_FIREWALL on mbuf, otherwise
  we may end up with infinite processing. [1]
- Update the copy-paste from ip_output() bringing in TSO and
  SCTP support.
- Reduce number of byte order swaps.

More cleanups and fixes to pf_route6():
- We don't need to check for m_len, pf_test() already did this.
- We don't need struct route_in6 on stack, a sockaddr_in6
  would be enough.
- In case if new interface (after routing rule applied) is
  a loopback one, then put M_SKIP_FIREWALL on mbuf, otherwise
  we may end up with infinite processing. [1]

# kldunload geom_vinum

or this:

GEOM_JOURNAL: Shutting down geom gjournal 3464572051.
panic: destroying non-empty racct: 1 allocated for resource 6

which were tracked by jh@ to be caused by checking p->p_flag,
while it wasn't initialised yet.  Basically, during fork, the code
checked p_flag, concluded the process isn't marked as P_SYSTEM,
incremented the counter, and later on, when exiting, checked that
the process was marked as P_SYSTEM, and thus didn't decrement it.

Also, I believe there wasn't any good reason for checking P_SYSTEM
in the first place.

Add MTAG_PERSISTENT to pf(4) tags. In OpenBSD they
store the pf(4) information right in the mbuf header,
and a persistent tag gives us similar behavior.

This flag is crucial for infinite recursion protection

Replace the MNT_VNODE_FOREACH interface with MNT_VNODE_FOREACH_ALL.
The primary changes are that the user of the interface no longer
needs to manage the mount-mutex locking and that the vnode that
is returned has its mutex locked (thus avoiding the need to check
to see if its is DOOMED or other possible end of life senarios).

To minimize compatibility issues for third-party developers, the
old MNT_VNODE_FOREACH interface will remain available so that this
change can be MFC'ed to 9. Following the MFC to 9, MNT_VNODE_FOREACH
will be removed in head.

The reason for this update is to prepare for the addition of the
MNT_VNODE_FOREACH_ACTIVE interface that will loop over just the
active vnodes associated with a mount point (typically less than
1% of the vnodes associated with the mount point).

Changes to the TCP offload code in the kernel.

input:
- Deliver stray packets for an offloaded connection to the TOE driver
  handling the connection.
- Inform the TOE driver when received data is consumed from the socket
  buffer.  This allows for forward progress in the rx path.

output:
- Have one central catch-all in tcp_output instead of various
  tcp_output_foo routines.  This ensures that the kernel never outputs
  anything for an offloaded connection and always kicks the TOE driver's
  tx routine instead.

timers:
- Do not arm any TCP timer for an offloaded connection.

syncache:
- Update the TOE driver when the entry it sought to add to the syncache
  is added or removed.  The kernel can call on a TOE driver to respond
  to a SYN anytime for an entry in the syncache so the TOE driver is
  expected to maintain state for entries that were added but have not
  been deleted yet.
- Do not skip any syncache checks simply because the entry is being
  added by a hardware TOE.

ctloutput
- Inform the TOE driver when setsockopt(2) changes any tcp(4) option of
  an offloaded socket.

Drop export of vdestroy() function from kern/vfs_subr.c as it is
used only as a helper function in that file. Replace sole call to
vbusy() with inline code in vholdl(). Replace sole calls to vfree()
and vdestroy() with inline code in vdropl().

The Clang compiler already inlines these functions, so they do not
show up in a kernel backtrace which is confusing. Also you cannot
set their frame in kgdb which means that it is impossible to view
their local variables. So, while the produced code is unchanged,
the debugging should be easier.

 - Implement "configure" command to allow switching operation mode of
running device on-fly without destroying and recreation.
 - Implement Active/Read mode as hybrid of Active/Active and Active/Passive.
In this mode all paths not marked FAIL may handle reads same time,
but unlike Active/Active only one path handles write requests at any
point in time. It allows to closer follow original write request order
if above layers need it for data consistency (not waiting for requisite
write completion before sending dependent write).
 - Hide duplicate messages about device status change.
 - Remove periodic thread wake up with 10Hz rate.

Extract embed scope id and set it to sin6_scope_id in struct sockaddr_in6 for
userland from the kernel via routing socket or sysctl.  The
net.inet6.ip6.deembed_scopeid sysctl variable controls this behavior.  The
default value is 1, and 0 means no de-embed.

De-embed of scope id in userland utilities have been removed except for
netstat(1) because it directly uses kvm to read the FIB entries, not sysctl or
routing socket.

Remove the magic mfi_array is 288 bytes and just use the
sizeof the array since it is not 288 bytes.

Change reporting of a "SYSTEM" disk to "JBOD" to match
LSI MegaCli and firmware reporting.

This means that mfiutil command to "create jbod" is now a
little confusing since a RAID per drive is not really what
LSI defines JBOD to be.  This should be fixed in the future
and support added to really create LSI JBOD and enable that
feature on cards that support it.

Make usbusN interface clonable and usbdump(8) create the interface dynamically
when necessary.  This mitigates the problem that the extra pseudo-interfaces
enlarge the interface list and confuse the user.  The hw.usb.no_pf knob has
been removed.

Instead of using IFF_CANTCONFIG, the usbusN interfaces reject any ioctls for
interface configuration intentionally.  Also, set ifp->if_afdata[AF_INET6]

The only platform I've seen this on is the AR9220 when attached to
the AR71xx CPUs.  I get immediate PCIe bus errors and all subsequent
accesses cause further MIPS bus exceptions.  I don't have any other
big-endian platforms to test this on.

If I get a chance (or two), I'll try to whack this on a bus analyser
and see exactly what happens.

I'd rather leave this on, especially for slower, embedded platforms.

Restore per mount-point counts of synchronous and asynchronous
reads and writes associated with UFS and MSDOS filesystems.

MFS 233627:
Keep track of the mount point associated with a special device
to enable the collection of counts of synchronous and asynchronous
reads and writes for its associated filesystem. The counts are
displayed using `mount -v'.

Ensure that buffers used for paging indicate the vnode from
which they are operating so that counts of paging I/O operations
from the filesystem are collected.

This checkin only adds the setting of the mount point for the
UFS/FFS filesystem, but it would be trivial to add the setting
and clearing of the mount point at filesystem mount/unmount
time for other filesystems too.

MFC of 233817:

A file cannot be deallocated until its last name has been removed
and it is no longer referenced by a user process. The inode for a
file whose name has been removed, but is still referenced at the
time of a crash will still be allocated in the filesystem, but will
have no references (e.g., they will have no names referencing them
from any directory).

With traditional soft updates these unreferenced inodes will be
found and reclaimed when the background fsck is run. When using
journaled soft updates, the kernel must keep track of these inodes
so that it can find and reclaim them during the cleanup process.
Their existence cannot be stored in the journal as the journal only
handles short-term events, and they may persist for days. So, they
are tracked by keeping them in a linked list whose head pointer is
stored in the superblock. The journal tracks them only until their
linked list pointers have been commited to disk. Part of the cleanup
process involves traversing the list of unreferenced inodes and
reclaiming them.

This bug was triggered when confusion arose in the commit steps
of keeping the unreferenced-inode linked list coherent on disk.
Notably, a race between the link() system call adding a link-count
to a file and the unlink() system call removing a link-count to
the file. Here if the unlink() ran after link() had looked up
the file but before link() had incremented the link-count of the
file, the file's link-count would drop to zero before the link()
incremented it back up to one. If the file was referenced by a
user process, the first transition through zero made it appear
that it should be added to the unreferenced-inode list when in
fact it should not have been added. If the new name created by
link() was deleted within a few seconds (with the file still
referenced by a user process) it would legitimately be a candidate
for addition to the unreferenced-inode list. The result was that
there were two attempts to add the same inode to the unreferenced-inode
list which scrambled the unreferenced-inode list's pointers leading
to a panic. The fix is to detect and avoid the false attempt at
adding it to the unreferenced-inode list by having the link()
system call check to see if the link count is zero before it
increments it. If it is, the link() fails with ENOENT (showing that
it has failed the link()/unlink() race).

While tracking down this bug, we have added additional assertions
to detect the problem sooner and also simplified some of the code.

- place some asserts
- add veryfing FS revision at mount time
- rmdir without this operation left invalid data in inode
- file created right after deleted directory appeared as directory
- reduce inode size of removed directory to 0 (similar to ext2fs, msdosfs)
- check if inode has any links during lookup (similar to ufs)
- protect write entry points by very same lock used to protect segment
  construction - this servers as our own version of vfs_write_suspend
- ignore MNT_LAZY syncs - this is a hack used to ignore periodic syncs

This change creates a new list of active vnodes associated with
a mount point. Active vnodes are those with a non-zero use or hold
count, e.g., those vnodes that are not on the free list. Note that
this list is in addition to the list of all the vnodes associated
with a mount point.

To avoid adding another set of linkage pointers to the vnode
structure, the active list uses the existing linkage pointers
used by the free list (previously named v_freelist, now renamed
v_actfreelist).

This update adds the MNT_VNODE_FOREACH_ACTIVE interface that loops
over just the active vnodes associated with a mount point (typically
less than 1% of the vnodes associated with the mount point).

This update uses the MNT_VNODE_FOREACH_ACTIVE interface that loops
over just the active vnodes associated with a mount point to replace
MNT_VNODE_FOREACH_ALL in the vfs_msync, ffs_sync_lazy, and qsync
routines.

The vfs_msync routine is run every 30 seconds for every writably
mounted filesystem. It ensures that any files mmap'ed from the
filesystem with modified pages have those pages queued to be
written back to the file from which they are mapped.

The ffs_lazy_sync and qsync routines are run every 30 seconds for
every writably mounted UFS/FFS filesystem. The ffs_lazy_sync routine
ensures that any files that have been accessed in the previous
30 seconds have had their access times queued for updating in the
filesystem. The qsync routine ensures that any files with modified
quotas have those quotas queued to be written back to their
associated quota file.

In a system configured with 250,000 vnodes, less than 1000 are
typically active at any point in time. Prior to this change all
250,000 vnodes would be locked and inspected twice every minute
by the syncer. For UFS/FFS filesystems they would be locked and
inspected six times every minute (twice by each of these three
routines since each of these routines does its own pass over the
vnodes associated with a mount point). With this change the syncer
now locks and inspects only the tiny set of vnodes that are active.

Introduce the matching PCI ath(4) fixup code from ar71xx_pci into
ar724x_pci.c.

* Move out the code which populates the firmware into ar71xx_fixup.c
* Shuffle around the ar724x fixup code to match what the ar71xx fixup
  code does.

I've validated this on an AR7240 with AR9285 on-board NIC. It doesn't
yet load, as the AR9285 EEPROM code needs to be made "flash aware."

TODO:

* Validate that I haven't broken AR71xx
* Test AR9285/AR9287 onboard NICs, complete with EEPROM code changes
* Port over the needed BAR hacks for AR7240, AR7241 and AR7242 from
  Linux OpenWRT.  The current WAR has only been tested on the AR7240
  and I'm not sure the way the BAR register is treated is "right".
  The "fixup" method here is right when setting the BAR for local access -
  ie, the BAR address is either 0xffff (AR7240) or 0x1000ffff (AR7241/AR7242),
  but the ath9k-fixup.c code (Linux OpenWRT) does this when setting the
  initial "fixup" BAR.  It then restores the original BAR.
  I'll have to read the ar724x PCI bus glue to see what other special cases
  await.
