iwlwifi: fix scan abort
Fix possible double priv->mutex lock introduced by commit
a69b03e941abae00380fc6bc1877fb797a1b31e6
"iwlwifi: cancel scan watchdog in iwl_bg_abort_scan" .
We can not call cancel_delayed_work_sync(&priv->scan_check) with
priv->mutex locked because workqueue function iwl_bg_scan_check()
take that lock internally.
We do not need to synchronize when canceling priv->scan_check work.
We can avoid races (sending double abort command or send no
command at all) using STATUS_SCAN_ABORT bit. Moreover
current iwl_bg_scan_check() code seems to be broken, as
we should not send abort commands when currently aborting.

mac80211: inform drivers about the off-channel status on channel changes
For some drivers it can be useful to know whether the channel they're
supposed to switch to is going to be used for short off-channel work or
scanning, or whether the hardware is expected to stay on it for a while
longer. This is important for various kinds of calibration work, which
takes longer to complete and should keep some persistent state, even if
the channel temporarily changes.

Revert "mac80211: fix sw scan bracketing"
This reverts this commit. While in theory the change is
correct the patch does not address current assumptions made
by some drivers, one which is definitley affected is ath9k.
Prior to this change the scan complete callback would be
called after we returned to the home channel and configured
the hardware RX filters. After this change we call the scan
complete callback prior to both the hw config and the config
filter. At least for ath9k this breaks quite a few assumptions
on the callback, leading to disconnects to the AP after every scan
making the driver pretty useless on STA mode. The goal behind
this commit was to address the now understood spurious warnings
from ath9k and mac80211_hwsim on scanning on two wiphys at the
same time but we have now supressed these and will address this
issue in the next kernel release.
When fixing this for good next we must first review the other
driver's dependence on this logic and perhaps consider removal
of the scan complete callback all together.

When issuing two consecutive scans you could often end up
getting in the logs:
"ath9k: Two wiphys trying to scan at the same time"
This message is due to a race in mac80211 but addressing
that race requires some more major changes on the driver

rt2x00: Fix regression for rt2500pci

rt2x00: Write the BSSID to register when interface is added
mananged mode in rt2500pci was broken, due to intf->bssid containing
random data rather then the expected 00:00:00:00:00:00
This is corrected by sending the BSSID to rt2x00lib_config_intf
only in AP mode where the bssid is set to a valid value.

ath9k_hw: simplify noisefloor calibration chainmask calculation
The noisefloor array index always corresponds to the rx chain number it
belongs to (with an offset of 3 for the extension chain).
It's much simpler (and actually more correct) to directly use the
chainmask to calculate the bitmask for the noisefloor array, instead of
using these weird chip revision checks and hardcoded mask values.

iwl-agn.c:1861: warning: ‘tlv_type’ may be used uninitialized in this function
iwl-agn.c:1862: warning: ‘tlv_data’ may be used uninitialized in this function
This is almost correct but we do do break out of the TLV
parsing loop when setting ret. However, the code is hard
to follow, and clearly even the compiler is having issues
with it too.
Additionally, however, the current code is wrong. If there
is a TLV length check error, the code will report
invalid TLV after parsing: ...
because "len" will still be non-zero as we broke out of
the loop.
So to remove the warning and fix that issue, make the code
easier to read by doing length checking with an error label.
As a result, we can completely remove the "ret" variable.
Also, while at it, remove the "fixed_tlv_size" variable
since each TLV type has its own specified length, it just
happens that we have only variable length, flags (0 length)
and u32 TLVs right now. It should still be checked with more

mac80211: fix IBSS lockdep complaint
Bob reported a lockdep complaint originating in
the mac80211 IBSS code due to the common work
struct patch. The reason is that the IBSS and
station mode code have different locking orders
for the cfg80211 wdev lock and the work struct
(where "locking" implies running/canceling).
Fix this by simply not canceling the work in
the IBSS code, it is not necessary since when
the REQ_RUN bit is cleared, the work will run
without effect if it runs. When the interface
is set down, it is flushed anyway, so there's
no concern about it running after memory has
been invalidated either.

Additionally, looking into this I noticed that
there's a small window while the IBSS is torn
down in which the work may be rescheduled and
the REQ_RUN bit be set again after leave() has
cleared it when a scan finishes at exactly the
same time. Avoid that by setting the ssid_len
to zero before clearing REQ_RUN which signals
to the scan finish code that this interface is
not active.

mac80211: refuse shared key auth when WEP is unavailable
When WEP is not available, we should reject shared
key authentication because it could never succeed.

cfg80211: fix race between sysfs and cfg80211
device_add() is called before adding the phy to the cfg80211 device
list.
So if a userspace program uses sysfs uevents to detect new phy
devices, and queries nl80211 to get phy info, it can get ENODEV even
though the phy exists in sysfs.
An easy workaround is to hold the cfg80211 mutex until the phy is
present in sysfs/cfg80211/debugfs.

AFAICT, none of these amount to real bugs. But this reduces warning
spam from sparse w/o significantly affecting readability of the code (IMHO).
