dee8a9732e cfg80211: don't request disconnect if not connected
Neil Brown reports that with libertas, my recent cfg80211
SME changes in commit ceca7b7121
("cfg80211: separate internal SME implementation") broke
libertas suspend because it we now asked it to disconnect
while already disconnected.

The problematic change is in cfg80211_disconnect() as it
previously checked the SME state and now calls the driver
disconnect operation unconditionally.

Fix this by checking if there's a current_bss indicating
a connection, and do nothing if not.

cb35fba360 nl80211: nl80211hdr_put() doesn't return an ERR_PTR
There are a few places which check nl80211hdr_put() for an ERR_PTR
but actually it returns NULL on error and never error values.  In
nl80211_testmode_dump() the return wasn't checked at all so I have
added one.

5a6e0cf707 cw1200: Fix spurious BUG_ON() trigger when starting AP mode.
There's an underlying race condition with the unjoin_work() call that is
sometimes triggered depending on scheduling order and the phase of the
moon.  This doesn't fix the race condition, but it does remove the
ill-advised BUG_ON() call in an easily-recoverable situation.

ddfe49b42d mac80211: continue using disabled channels while connected
In case the AP has different regulatory information than we do,
it can happen that we connect to an AP based on e.g. the world
roaming regulatory data, and then update our database with the
AP's country information disables the channel the AP is using.
If this happens on an HT AP, the bandwidth tracking code will
hit the WARN_ON() and disconnect. Since that's not very useful,
ignore the channel-disable flag in bandwidth tracking.

5cdaed1e87 mac80211: ignore HT primary channel while connected
While we're connected, the AP shouldn't change the primary channel
in the HT information. We checked this, and dropped the connection
if it did change it.

Unfortunately, this is causing problems on some APs, e.g. on the
Netgear WRT610NL: the beacons seem to always contain a bad channel
and if we made a connection using a probe response (correct data)
we drop the connection immediately and can basically not connect
properly at all.

Work around this by ignoring the HT primary channel information in
beacons if we're already connected.

Also print out more verbose messages in the other situations to
help diagnose similar bugs quicker in the future.

b56e4b857c mac80211: fix infinite loop in ieee80211_determine_chantype
Commit "3d9646d mac80211: fix channel selection bug" introduced a possible
infinite loop by moving the out target above the chandef_downgrade
while loop.  When we downgrade to NL80211_CHAN_WIDTH_20_NOHT, we jump
back up to re-run the while loop...indefinitely.  Replace goto with
break and carry on.  This may not be sufficient to connect to the AP,
but will at least keep the cpu from livelocking.  Thanks to Derek Atkins
as an extra pair of debugging eyes.

This patch fixes an issue wherein association would fail on P2P

infrastructure stations, it would fail P2P clients for which mode

Better check would be bss_role which has only 2 values: STA/AP.

wiphy index. Similar code in nl80211_testmode_dump() correctly

e2288b66fe rt2x00: fix stop queue
Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following
call to rt2x00queue_pause_queue() reduce to noop, i.e we do not
stop queue in mac80211.

To fix that introduce rt2x00queue_pause_queue_nocheck() function,
which will stop queue in mac80211 directly.

Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit.

Note also that reordering operations i.e. first call to
rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race
with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue()
directly is the only available solution to fix the problem without
major rework.

53e21fbc28 Bluetooth: Fix calling request callback more than once
In certain circumstances, such as an HCI driver using __hci_cmd_sync_ev
with HCI_EV_CMD_COMPLETE as the expected completion event there is the
chance that hci_event_packet will call hci_req_cmd_complete twice (once
for the explicitly looked after event and another time in the actual
handler of cmd_complete).

In the case of __hci_cmd_sync_ev this introduces a race where the first
call wakes up the blocking __hci_cmd_sync_ev and lets it complete.
However, by the time that a second __hci_cmd_sync_ev call is already in
progress the second hci_req_cmd_complete call (from the previous
operation) will wake up the blocking function prematurely and cause it
to fail, as witnessed by the following log:

When the device is physically connected the driver sends a disassoc
command to the device and response triggers the driver to inform cfg80211
about it. However, with the device removed the disassoc command fails.
This patch adds a call to cfg80211_disconnected() when that command fails.

The warning was added by commit below and also cleans up, but better
doing it in the driver if only to get rid of the warning.

d9c78e9738 Bluetooth: fix wrong use of PTR_ERR() in btusb
PTR_ERR() returns a signed long type value which is limited by IS_ERR(),
it must be a negative number whose range is [-MAX_ERRNO, 0).

The bug here returns negative numbers as error codes, then check it by
"if (ret < 0)", but -PTR_ERR() is actually positive. The wrong use here
leads to failure as below, even panic.

Unfortunately, the firmware only supports replay counters for

will walk through the keys in order of their addition, simply
use the same HW key index (1) for all GTKs, thus overwriting
previous ones with newer ones. The replay counters for it are
already used.
