a16cd9c05e jwd@ reported via email that the "CacheSize" field reported by "nfsstat -e -s"
would go negative after using the "-z" option to zero out the stats.
This patch fixes that by not zeroing out the srvcache_size field
for "-z", since it is the size of the cache and not a counter.

9a7e6bac47 Consumers of bpfdetach() expect it to remove all bpf_if structs from the
bpf_iflist list which reference the specified ifnet. The existing implementation
only removes the first matching bpf_if found in the list, effectively leaking
list entries if an ifnet has been bpfattach()ed multiple times with different
DLTs.

Fix the leak by performing the detach logic in a loop, stopping when all bpf_if
structs referencing the specified ifnet have been detached and removed from the
bpf_iflist list.

Whilst here, also:

- Remove the unnecessary "bp->bif_ifp == NULL" check, as a bpf_if should never
  exist in the list with a NULL ifnet pointer.

- Except when INVARIANTS is in the kernel config, silently ignore the case where
  no bpf_if referencing the specified ifnet is found, as it is harmless and does
  not require user attention.

6791e4f442 Get rid of a spurious warning on the console when booting the kernel
from the interactive loader(8) prompt and beastie_disable="YES" is set
in loader.conf(5). In this case menu.rc is not evaluated and consequently
menu-unset does not have a body yet. This results in the ficl warning
"menu-unset not found" when try-menu-unset invokes menu-unset.

Check for beastie_disable="YES" explicitly, so that the try-menu-unset
word will not attempt to invoke menu-unset because the menu will have
never been configured. [1]
Use the sfind primitive as a last resort as an additional safer approach
conjuring a foreign word safely. [2]

5c39f7bdeb Bunch of fixes to pfsync(4) module load/unload:
o Make the pfsync.ko actually usable. Before this change loading it
  didn't register protosw, so was a nop. However, a module /boot/kernel
  did confused users.
o Rewrite the way we are joining multicast group:
  - Move multicast initialization/destruction to separate functions.
  - Don't allocate memory if we aren't going to join a multicast group.
  - Use modern API for joining/leaving multicast group.
  - Now the utterly wrong pfsync_ifdetach() isn't needed.
o Move module initialization from SYSINIT(9) to moduledata_t method.
o Refuse to unload module, unless asked forcibly.
o Improve a bit some FreeBSD porting code:
  - Use separate malloc type.
  - Simplify swi sheduling.

This change is probably wrong from VIMAGE viewpoint, however pfsync
wasn't VIMAGE-correct before this change, too.

3ab0160340 Avoid LOR between vfs_busy() lock and covered vnode lock on quotaon().
The vfs_busy() is after covered vnode lock in the global lock order, but
since quotaon() does recursive VFS call to open quota file, we usually
end up locking covered vnode after mp is busied in sys_quotactl().

Change the interface of VFS_QUOTACTL(), requiring that mp was unbusied
by fs code, and do not try to pick up vfs_busy() reference in ufs quotaon,
esp. if vfs_busy cannot succeed due to unmount being performed.

2971897d51 Correct an error of omission in the implementation of the truncation
operation on POSIX shared memory objects and tmpfs.  Previously, neither of
these modules correctly handled the case in which the new size of the object
or file was not a multiple of the page size.  Specifically, they did not
handle partial page truncation of data stored on swap.  As a result, stale
data might later be returned to an application.

Interestingly, a data inconsistency was less likely to occur under tmpfs
than POSIX shared memory objects.  The reason being that a different mistake
by the tmpfs truncation operation helped avoid a data inconsistency.  If the
data was still resident in memory in a PG_CACHED page, then the tmpfs
truncation operation would reactivate that page, zero the truncated portion,
and leave the page pinned in memory.  More precisely, the benevolent error
was that the truncation operation didn't add the reactivated page to any of
the paging queues, effectively pinning the page.  This page would remain
pinned until the file was destroyed or the page was read or written.  With
this change, the page is now added to the inactive queue.

f725864490 opt_inet6.h was missing from some files in the new NFS subsystem.
The effect of this was, for clients mounted via inet6 addresses,
that the DRC cache would never have a hit in the server. It also
broke NFSv4 callbacks when an inet6 address was the only one available
in the client. This patch fixes the above, plus deletes opt_inet6.h

This is just a build workaround. If you're actively using wireless,

The real solution is to make the module build depend if AH_SUPPORT_AR5416

93e26ff438 Fix the ar724x shift calculation when writing to the PCI config space.
This was preventing the ath driver from being loaded at runtime.
It worked fine when compiled statically into the kernel but not when
kldload'ed after the system booted.

The root cause was that PCIR_INTLINE (register 60) was being
overwritten by zeros when register 62 was being written to.
A subsequent read of this register would return 0, and thus
the rest of the PCI glue assumed an IRQ resource had already
been allocated.  This caused the device to fail to attach at
runtime as the device itself didn't contain any IRQ resources.

TODO: go back over the ar71xx and ar724x PCI config read/write
code and ensure it's correct.

d467c9472a r222004 changed sbuf_finish() to not clear the buffer error status. As a
consequence sbuf_len() will return -1 for buffers which had the error
status set prior to sbuf_finish() call. This causes a problem in
pfs_read() which purposely uses a fixed size sbuf to discard bytes which
are not needed to fulfill the read request.

Work around the problem by using the full buffer length when
sbuf_finish() indicates an overflow. An overflowed sbuf with fixed size
is always full.

1e96ae8193 Remove the assertion from tcp_input() that rcv_nxt is always greater
than or equal to rcv_adv and fix tcp_twstart() to handle this case by
assuming the last window was zero rather than a negative value.

The code in tcp_input() already safely handled this case.  It can happen
due to delayed ACKs along with a remote sender that sends data beyond
the window we previously advertised.  If we have room in our socket buffer
for the extra data beyond the advertised window, we will accept it.
However, if the ACK for that segment is delayed, then we will not
effectively fixup rcv_adv to account for that extra data until the
next segment arrives and forces out an ACK.  When that next segment
arrives, rcv_nxt will be beyond rcv_adv.

8f5aa976d7 This isn't required any longer - it turns out the flash
has ~ 1.7MB of space for a kernel.  There's thus plenty of
space for a full, non-module kernel.

188da34c00 Re-enable this bit of logic from before, which only sets a default
opt_ah.h file if KERNBUILDDIR isn't defined.

For now, AH_SUPPORT_AR5416 is required, so I'll just fix any
configuration file in /usr/src which is missing this option.

b018dade46 Use geom_uncompress now, rather than geom_uzip.
This results in a much smaller rootfs image and it easily
fits in the 8MB flash.

e65919f9fc Do not restart the scan in vm_object_page_clean() on the object
generation change if requested mode is async. The object generation is
only changed when the object is marked as OBJ_MIGHTBEDIRTY. For async
mode it is enough to write each dirty page, not to make a guarantee that
all pages are cleared after the vm_object_page_clean() returned.

19b0c9b246 Use the mli_relinmhead list normally used to defer calls to
in6m_release_locked() to defer calls to mld_v1_transmit_report() until
after the IF_ADDR_LOCK is dropped.  This removes a race where the lock
is dropped and reacquired while attempting to walk an interface's
address list.

5a1e37174f Add special loader environment variables 'comconsole_port' and
'comconsole_pcidev'. The former allows to set the base address of the
serial console i/o port. The later takes the string of the format
'bus:device:function:[bar]' as a value and uses the serial port attached
as PCI device at the specified location for console.

Both variants pass 'hw.uart.console' variable to the uart driver to
properly hand-over the kernel console.

Change allows to use ISA serial ports other than COM1 for the
loader/kernel console without loader recompilation. Also, you can use
PCI-attached port as the console, e.g. Intel AMT serial pseudo-port on
some motherboards based on Q67 chipset.

dd0f9532f3 Do the vput() for the lowervp in the null_nodeget() for error case too.
Several callers of null_nodeget() did the cleanup itself, but several
missed it, most prominent being null_bypass(). Remove the cleanup from
the callers, now null_nodeget() handles lowervp free itself.
