96acc1b61c Explicitly ignore ibss merge requests when the node is ic_bss. This can
happen on the first management frame received from a neighbor; we assume
any merge candidate will send more frames and those should be processed
with a suitable table entry.

3fcfbbfa76 Simplify the logic for checking the scan candidates at the end of a scan.
Hold a lock on the table instead of futzing with reference counts which
was potentially dangerous except drivers were quiescent while we did this
so the table contents never changed.  Disable the hack logic for removing
scan candidates with multiple association failures; it's never done the
right thing and will be fixed correctly with background scanning goes in.

44c72e4299 move beacon/probe response counting down to after we've decided whether or
not we're going to process the frame; this makes the counters reflect frames

2045f69945 fixup inactivity timers:
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

5e923d2ebd Relearn how WPA keying is supposed to work and fix WPA+WME while
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

af5e59bf28 Add a new network interface flag, IFF_NEEDSGIANT, which will allow
device drivers to declare that the ifp->if_start() method implemented
by the driver requires Giant in order to operate correctly.

Add a 'struct task' to 'struct ifnet' that can be used to execute a
deferred ifp->if_start() in the event that if_start needs to be called
in a Giant-free environment.  To do this, introduce if_start(), a
wrapper function for ifp->if_start().  If the interface can run MPSAFE,
it directly dispatches into the interface start routine.  If it can't
run MPSAFE, we're running with debug.mpsafenet != 0, and Giant isn't
currently held, the task is queued to execute in a swi holding Giant
via if_start_deferred().

Modify if_handoff() to use if_start() instead of direct dispatch.
Modify 802.11 to use if_start() instead of direct dispatch.

This is intended to provide increased compatibility for non-MPSAFE
network device drivers in the presence of Giant-free operation via
asynchronous dispatch.  However, this commit does not mark any network
interfaces as IFF_NEEDSGIANT.

36c6538b7f Change handling of probe response frames. Previously we always dropped the
refcnt on the node but left it in the node table.  This allows the node table
to hold the results of scanned ap's but for ibss scans left nodes w/o any
driver-private state setup and/or a bad refcnt (when the nodes were timed
out they were prematurely discarded).  Now we treat nodes identified for ap
scanning as before but force nodes discovered when scanning for ibss neighbors
to have complete/proper state and hold the refcnt on the node.  Any other
nodes created because of these frames are discarded directly (need to optimize
this case to eliminate various work that's immediately discarded).

o add ieee80211_find_txnode routine to lookup a node by mac address and
  if not present create one when operating in ibss/ahdemo mode; new nodes
  are dup'd from bss and the driver is told to treat the node as if a new
  association has been created so driver-private state (e.g. rate control
  handling) is setup

may pass up into the 802.11 layer

4f2e09c4b2 Honor the short preamble capability/state flag when calculating the
capabilities for outbound management frames.  But beware of sending
this when operating on 5GHz channels; some 11a AP's reject association
requests if this bit is set in the capabilities listed.

0a915fad5d MFp4 changes to fix locking issues and correct reference
count handling of station entries in hostap mode:

Input path:

o driver is now expected to find the node associated with the
  sender of a received frame; use ic_bss if none is located
o driver passes the (referenced) node into ieee80211_input for
  use within the wlan module and is responsible for cleaning up
  on return
o the antenna state is no longer passed up with each frame; this
  is now considered driver-private state and drivers are responsible
  for keeping it in the driver-private part of a node

Output path:

Revamp output path for management frames to eliminate redundant
locking that causes problems and to correct reference counting
bogosity that occurs when stations are timed out due to inactivity
(in AP mode).  On output the refcnt'd node is stashed in the pkthdr's
recvif field (yech) and retrieved by the driver.  This eliminates
an unref/ref scenario and related node table unlock/lock due to the
driver looking up the node.  This is particularly important when
stations are timed out as this causes a lock order reversal that
can result in a deadlock.  As a byproduct we also reduce the overhead
for sending management frames (minimal).  Additional fallout from
this is a change to ieee80211_encap to return a refcn't node for
tieing to the outbound frame.  Node refcnts are not reclaimed until
after a frame is completely processed (e.g. in the tx interrupt
handler).  This is especially important for timed out stations as
this deref will be the final one causing the node entry to be
reclaimed.

Additional semi-related changes:
o replace m_copym use with m_copypacket (optimization)
o add assert to verify ic_bss is never free'd during normal operation
o add comments explaining calling conventions by drivers for frames
  going in each direction
o remove extraneous code that "cannot be executed" (e.g. because
  pointers may never be null)

2692bb26d4 Delay creating ic_bss until after the super-class has a chance
to override the method pointers for manipulating nodes; this fixes
a problem where the ic_bss node was not being created properly
for the ath driver causing the driver to scribble on random memory.

dd0e6ea6b0 Use IEEE80211_RATE_MAXSIZE instead of IEEE80211_RATE_SIZE to validate the
rate set element id from an AP.  This allows stations to associate with
AP's that violate the 802.11 spec by sending >8 rates.  This corrects a
recent regression; older code did likewise.

a11c9a5cc2 o change ieee80211_new_state handling to use a proper method that drivers
override in their sub-class; this eliminates the hack of interpreting the
  EINPROGRESS return value to mean "don't do any of the normal work"
o correct active scanning so the first channel is only scanned once and so
  per-channel passive mode is properly honored
o expose 802.11 FSM state names so every driver doesn't keep a private copy
o eliminate node parameter to ieee80211_begin_scan; it was not being used

o code reorg (relative to old netbsd-derived code) for future growth
o drivers now specify available channels and rates and 802.11 layer handles
  almost all ifmedia actions
o multi-mode support for 11a/b/g devices
o 11g protocol additions (incomplete)
o new element id additions (for other than 11g)
o node/station table redone for proper locking and to eliminate driver
  incestuousness
o split device flags and capabilities to reduce confusion and provide room
  for expansion
o incomplete power management infrastructure (need to revisit)
o incomplete hooks for software retry
o more...
