o Add field to dev_desc for the size of the io port range. This isn't
used yet in the committed sources, but will make the transition easier
in the future.
If you build this into your kernel, you will need to rebuild pccardd.
_or_ you may specify "log logamount number" to set logging specifically
the rule.
In addition, "ipfw resetlog" has been added, which will reset the
logging counters on any/all rule(s). ipfw resetlog does not affect
the packet/byte counters (as ipfw reset does), and is the only "set"
command that can be run at securelevel >= 3.
This should address complaints about not being able to set logging
amounts, not being able to restart logging at a high securelevel,
and not being able to just reset logging without resetting all of the
counters in a rule.
Specifically intended for removing -fschg ("INSTALLFLAGS_EDIT=:S/schg/uchg/")
this makes the NOFSCHG flag redundant. NOFSCHG will still be honoured by
bsd.lib.mk but is valid for buildworld only. NOFSCHG is still implemented in
the old way (ie. _not_ ".if NOFSCHG then { INSTALLFLAGS_EDIT+=:S/schg/,/ }"
to emphasize the fact that NOFSCHG is only supported in a limited
fashion and for buildworld.
The interface and implementation are such that future use of flags such
as sappnd can also be easily removed or altered (perhaps to uappnd).

Remove the initialization of PQ_NONE's cnt and lcnt. They aren't
used.
vm_page_insert:
Remove an unnecessary dereference.
vm_page_wire:
Remove the one and only (and thus pointless) reference
to PQ_NONE's lcnt.
I did some tcpdumping the other day and noticed that GETATTR calls
were frequently followed by an ACCESS call to the same file. The
attached patch changes nfs_getattr to fill the access cache as a side
effect. This is accomplished by calling ACCESS rather than
GETATTR. This implies a modest overhead of 4 bytes in the request and
8 bytes in the response compared to doing a vanilla GETATTR.
...
[The patch comprises two parts] The first
is the "real" patch, the second counts misses and hits rather than
fills and hits. The difference is subtle but important because both
nfs_getattr and nfs_access now fill the cache. It also changes the
default value of nfsaccess_cache_timeout to better match the attribute
cache. IMHO, file timestamps change much more frequently than
protection bits.

Panic was caused when major() and minor() were called with args which
weren't pointers. The panic was probably introduced in rev 1.51 of
kern_conf.c
vnodes are locked and never unlocked, which leads to processes starting
to wedge up after doing a mount -o nfsv3,tcp,rdirplus foo:/fs /fs; ls /fs.
The second is that sometimes cnp is accessed without having been
properly initialized: cnp->cn_nameptr points to an earlier name while
"len" contains the length of a current name of different size. This
leads to an attempt to dereference *(cn->cn_nameptr + len) which will
sometimes cause a page fault and a panic.
With these two fixes, client side readdirplus works correctly with
FreeBSD, IRIX 6.5.4 and Solaris 2.5.1 and 2.6 servers.

being incremented by 4 bytes too few each time through the loop, which
allows more data into the mbuf chain that we really want. In the worst
case, when we're using 32K read/write sizes with a TCP client, this causes
readdirplus replies to sometimes exceed NFS_MAXPACKET which leads to a
panic. This problem cropped up for me using an IRIX 6.5.4 NFSv3 TCP client
with 32K read/write sizes, however supposedly it can be triggered by
WinNT NFS servers too. In theory, it can probably be triggered by any
NFS v3 implementation using TCP as long as it's using the maxiumum block
size.

- device_print_child() either lets the BUS_PRINT_CHILD
method produce the entire device announcement message or
it prints "foo0: not found\n"
Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on
the previous behavior of device_print_child() (printing the
"foo0: <FooDevice 1.1>" bit of the announce message.)
Provide bus_print_child_header() and bus_print_child_footer()
to actually print the output for bus_generic_print_child().
These functions should be used whenever possible (unless you can
just use bus_generic_print_child())
The BUS_PRINT_CHILD method now returns int instead of void.
Modify everything else that defines or uses a BUS_PRINT_CHILD
method to comply with the above changes.
- Devices are 'on' a bus, not 'at' it.
- If a custom BUS_PRINT_CHILD method does the same thing
as bus_generic_print_child(), use bus_generic_print_child()
- Use device_get_nameunit() instead of both
device_get_name() and device_get_unit()
- All BUS_PRINT_CHILD methods return the number of
characters output.
