a33d402610 cfg80211: fix compilation warning for cfg80211_leave_all()
The following compilation issue popped up moving from v3.10-rc1 to
v3.10-rc6 after merging wireless-testing.

net/wireless/sysfs.c:86:13: error: 'cfg80211_leave_all' defined
but not used [-Werror=unused-function]

The function is only called when CONFIG_PM is enabled. Moving the
function under CONFIG_PM as well.

f1940c5730 cfg80211: hold BSS over association process
This fixes the potential issue that the BSS struct that we use
and later assign to wdev->current_bss is removed from the scan
list while associating.

Also warn when we don't have a BSS struct in connect_result
unless it's from a driver that only has the connect() API.

959867fa55 cfg80211: require passing BSS struct back to cfg80211_assoc_timeout
Doing so will allow us to hold the BSS (not just ref it) over the
association process, thus ensuring that it doesn't time out and
gets invisible to the user (e.g. in 'iw wlan0 link'.)

This also fixes a leak in mac80211 where it doesn't always release
the BSS struct properly in all cases where calling this function.
This leak was reported by Ben Greear.

3a5a423bb9 nl80211: fix attrbuf access race by allocating a separate one
Since my commit 3713b4e364 ("nl80211: allow splitting wiphy
information in dumps"), nl80211_dump_wiphy() uses the global
nl80211_fam.attrbuf for parsing the incoming data. This wouldn't
be a problem if it only did so on the first dump iteration which
is locked against other commands in generic netlink, but due to
space constraints in cb->args (the needed state doesn't fit) I
decided to always parse the original message. That's racy though
since nl80211_fam.attrbuf could be used by some other parsing in
generic netlink concurrently.

For now, fix this by allocating a separate parse buffer (it's a
bit too big for the stack, currently 1448 bytes on 64-bit). For
-next, I'll change the code to parse into the global buffer in
the first round only and then allocate a smaller buffer to keep
the data in cb->args.

52874a5e39 Revert "mac80211: in IBSS use the Auth frame to trigger STA reinsertion"
This reverts commit 6d810f1032

In this way an IBSS station will not use the AUTH messages
to trigger a state reinitialisation anymore.

The behaviour was racy and was not working properly.
It has been introduced to help wpa_supplicant to support
IBSS/RSN, however all the logic is now getting moved into
wpa_s itself which will also be in charge of handling the
AUTH messages thanks to the mgmt frame registration.

If userspace does not register for receiving AUTH frames
then mac80211 will still reply by itself.

At the same time, the auth frame registration counter can be
removed since it is not needed anymore.

35d865afbb mac80211: work around broken APs not including HT info
There are some APs, notably 2G/3G/4G Wifi routers, specifically the
"Onda PN51T", "Vodafone PocketWiFi 2", "ZTE MF60" and a similar
T-Mobile branded device [1] that erroneously don't include all the
needed information in (re)association response frames. Work around
this by assuming the information is the same as it was in the
beacon or probe response and using the data from there instead.

This fixes https://bugzilla.kernel.org/show_bug.cgi?id=58881.

[1] https://bbs.archlinux.org/viewtopic.php?pid=1277305

Note that this requires marking the first ieee802_11_parse_elems()
argument const, otherwise we'd get a compiler warning.

ceca7b7121 cfg80211: separate internal SME implementation
The current internal SME implementation in cfg80211 is
very mixed up with the MLME handling, which has been
causing issues for a long time. There are three things
that the implementation has to provide:
 * a basic SME implementation for nl80211's connect()
   call (for drivers implementing auth/assoc, which is
   really just mac80211) and wireless extensions
 * MLME events for the userspace SME
 * SME events (connected, disconnected etc.) for all
   different SME implementation possibilities (driver,
   cfg80211 and userspace)

To achieve these goals it isn't necessary to track the
software SME's connection status outside of it's state
(which is the part that caused many issues.) Instead,
track it only in the SME data (wdev->conn) and in the
general case only track whether the wdev is connected
or not (via wdev->current_bss.)

Also separate the internal implementation to not have
callbacks from the SME events, but rather call it from
the API functions that the driver (or rather mac80211)
calls. This separates the code better.

Do some cleanups in the cfg80211 SME APIs, which are
only used by mac80211.

Most of these functions get a frame passed, and there
isn't really any reason to export multiple functions
as cfg80211 can check the frame type instead, do that.

Additionally, the API functions have confusing names
like cfg80211_send_...() which was meant to indicate
that it sends an event to userspace, but gets a bit
confusing when there's both TX and RX and they're not
all clearly labeled.

c24bd3620c ath9k: Do not maintain ANI state per-channel

This reduces memory usage and since default values are used
during a scan run, per-channel state is not required.
