mincore(2) should check that the page is valid, not just allocated.
Otherwise, it can return a false positive for a page that is not yet
resident because it is being read from disk.

- Add a bunch of net80211 support so that 802.11 cards can be twiddled
with ifconfig. This still needs more work and is not guaranteed to
work for everyone. It works on my 802.11b/g card anyway.
The problem here is Microsoft doesn't provide a good way to a) learn
all the rates that a card supports (if it has more than 8, you're
kinda hosed) and b) doesn't provide a good way to distinguish between
802.11b, 802.11b/g an 802.11a/b/g cards, so you sort of have to guess.
Setting the SSID and switching between infrastructure/adhoc modes
should work. WEP still needs to be implemented. I can't find any API
for getting/setting the channel other than the registry/sysctl keys.
cpu could have been bogged down with non-transferable load and still not
migrated a new thread to an idle cpu. This required some benchmarking and
tuning to get right as the comment above it suggests.
otherwise they are initialized twice when the code is statically
configured in the kernel because the module load method gets
invoked before the user application calls ip_mrouter_init
o add a mutex to synchronize the module init/done operations; this
sort of was done using the value of ip_mroute but X_ip_mrouter_done
sets it to NULL very early on which can lead to a race against
ip_mrouter_init--using the additional mutex means this is safe now
o don't call ip_mrouter_reset from ip_mrouter_init; this now happens
once at module load and X_ip_mrouter_done does the appropriate
cleanup work to insure the data structures are in a consistent
state so that a subsequent init operation inherits good state

Correct the recovery thread's loop so that it

clear the recovery_thread proc pointer so that
any additional calls to aic_terminate_recovery_thread()
will not attempt to kill a thread that doesn't
exist. Lastly, code the loop so that termination
will still be successfull even if the termination
request occurs just prior to us entering the loop
or while the recovery thread is off recovering

As the referenced PR stated clearly, the old default setting of 0

spurious frame not only to put down a single PPPoE node running
FreeBSD, but to plague *every* FreeBSD node in a PPPoE network in
such a way that those nodes would keep poisoning each other until
rebooted simultaneously.

the PPPoE frame. Previously, ng_pppoe would start in standard
mode, yet switch to nonstandard one upon reception of a single
nonstandard frame. After having done so, ng_pppoe would be unable
to interact with standard PPPoE peers. Thus, a DoS condition
existed that could be triggered by a buggy peer or malicious party.
Since few people have expressed their displeasure WRT this problem,
the default operation of ng_pppoe is left untouched for now. However,
a new value for the sysctl net.graph.nonstandard_pppoe is introduced,
-1, which will force ng_pppoe stay in standard mode regardless of any
bogus frames floating around.

definitions for more than one device (usually differentiated by
the PCI subvendor/subdevice ID). Each device also has its own tree
of registry keys. In some cases, each device has the same keys, but
sometimes each device has a unique tree but with overlap. Originally,
I just had ndiscvt(8) dump out all the keys it could find, and we
would try to apply them to every device we could find. Now, each key
has an index number that matches it to a device in the device ID list.
This lets us create just the keys that apply to a particular device.
I also added an extra field to the device list to hold the subvendor
and subdevice ID.
Some devices are generic, i.e. there is no subsystem definition. If
we have a device that doesn't match a specific subsystem value and
we have a generic entry, we use the generic entry.
Implement this in acpi_MatchHid() and acpi_isa_get_compatid(). This
should fix mouse support for some users.
Move all users of AcpiGetObjectInfo() to use dynamic storage instead of
a devinfo on the stack. This is necessary since ACPI-CA needs to
allocate different sized arrays for the CompatList.

the socket layer during connection close, which requires locking
changes. To do this, introduce MAC Framework entry point
mac_create_mbuf_from_inpcb(), which is called from tcp_twrespond()
instead of calling mac_create_mbuf_from_socket() or
mac_create_mbuf_netlayer(). Introduce MAC Policy entry point
mpo_create_mbuf_from_inpcb(), and implementations for various
policies, which generally just copy label data from the inpcb to
the mbuf. Assert the inpcb lock in the entry point since we
require consistency for the inpcb label reference.
