the peer address by using M_WAITOK in ipx_setpeeraddr() to prevent
allocation failure. The socket reference used to reach these calls
will prevent the ipxpcb from being released prematurely.
properly handle the case where a connection is disconnected. The
queue(9)-enabled version of this code broke from the inner but not
outer loop, and so potentially frobbed an ipxpcb flag after the ipxpcb
was free'd, which might be picked up later by the malloc debugging
code. Properly break from the loop context and avoid touching the
cb/ipxpcb after free.
This seems to be able to extract a TOC and extract files from
the couple of ISO images I've tested it with.
Treat this as experimental proof-of-concept code for the
moment. There are still a bunch of debug messages (there
are a few oddities in ISO9660 that I haven't yet figured
out how to handle), a lot of bugs to be addressed (this
code leaks memory very badly), and a lot of missing features (no
Rockridge support, in particular). I'd appreciate
feedback from anyone who understands ISO9660 format
better than I do. ;-)

connection rates, which is causing problems for some users.
To retain the security advantage of random ports and ensure
correct operation for high connection rate users, disable
port randomization during periods of high connection rates.
Whenever the connection rate exceeds randomcps (10 by default),
randomization will be disabled for randomtime (45 by default)
seconds. These thresholds may be tuned via sysctl.
Many thanks to Igor Sysoev, who proved the necessity of this
change and tested many preliminary versions of the patch.

expects a locked route reference. This removes a panic that occurs
when connected ipxpcb is closed and its route free'd, and may have been
present since the route locking took place.

o implement double-extended and single precision loads and stores,
o implement double precision stores,
o replace the machdep.unaligned_print sysctl with debug.unaligned_print
and change the default value to 0,
o replace the machdep.unaligned_sigbus sysctl with debug.unaligned_test,
o Remmove the fillfd() function. The function is trvial enough for
inline assembly.
The debug.unaligned_test sysctl is used to test the emulation of
misaligned loads and stores. When PSR.ac is 0, the CPU will handle
misaligned memory accesses itselfi and we don't get an exception
for it. When PSR.ac is 1, the process needs to be signalled and we
should not emulate. The sysctl takes effect when PSR.ac is 1 and
tells us that we should emulate and not send a signal.

function provided by the driver limits allocations to the page size,
i.e. 4KB on i385 and 8KB on typical 64 bit processors. Since amd64
has 64 bit pointers, but only 4KB pages, an array of pointers that
just fits into one page on all the other processors, does require
2 pages on amd64.
In order to make this driver useful on amd64, the allocation unit
has been increased to 2 pages on amd64 and contigmalloc() is used
instead of malloc(). All other processor types are unaffected by
this change. This modification has only been compile-tested on
amd64, yet, but should just work (FLW).
machine; instead use the intended entry points. There's still
too much incestuous knowledge about the internals of the
802.11 layer but this at least fixes adhoc mode.
o ic_inact_auth is a bad name, it's the inactivity threshold
for being associated but not authorized; use it that way
o reset ni_inact when switching inactivity thresholds to
minimize the race against the timer (don't want to lock
for this stuff)
o change the inactivity probe threshold from a one-shot to
cover a range: when below this threshold but not expired
send a probe each inactivity interval; should probably
guard against the interval being turned way down as this
could cause us to spam the net with probes
we're at it:
o WPA/802.11i has a unicast key and a group key; in station mode
everything is sent with the unicast key--we were consulting the
destination mac address and incorrectly using the group key
o (perpetuate fallback use of the default tx key to maintain
compatibility with the way wpa_supplicant works)
o correct EAPOL encryption logic to check unicast key instead
of assuming other state implies this
o move QoS encapsulation up to before enmic work so TKIP has the
information required to calculate the pseudo-header
o do not do QoS-encapsulation of EAPOL frames as some ap's do the
wrong thing with such frames (may need to revisit this if ap's
start dropping non-QoS frames from stations assoc'd with QoS)
o move ieee80211_mbuf_adjust closer to its caller
