====================
pull request: wireless-next 2014-07-25
Please pull this batch of updates intended for the 3.17 stream!
For the mac80211 bits, Johannes says:
"We have a lot of TDLS patches, among them a fix that should make hwsim
tests happy again. The rest, this time, is mostly small fixes."
For the Bluetooth bits, Gustavo says:
"Some more patches for 3.17. The most important change here is the move of
the 6lowpan code to net/6lowpan. It has been agreed with Davem that this
change will go through the bluetooth tree. The rest are mostly clean up and
fixes."
and,
"Here follows some more patches for 3.17. These are mostly fixes to what
we've sent to you before for next merge window."
For the iwlwifi bits, Emmanuel says:
"I have the usual amount of BT Coex stuff. Arik continues to work
on TDLS and Ariej contributes a few things for HS2.0. I added a few
more things to the firmware debugging infrastructure. Eran fixes a
small bug - pretty normal content."
And for the Atheros bits, Kalle says:
"For ath6kl me and Jessica added support for ar6004 hw3.0, our latest
version of ar6004.
For ath10k Janusz added a printout so that it's easier to check what
ath10k kconfig options are enabled. He also added a debugfs file to
configure maximum amsdu and ampdu values. Also we had few fixes as
usual."
On top of that is the usual large batch of various driver updates --
brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action.
Rafał has also been very busy with b43 and related updates.
Also, I pulled the wireless tree into this in order to resolve a
merge conflict...
P.S. The change to fs/compat_ioctl.c reflects a name change in a
Bluetooth header file...

The functionality defined through these flags were actually firmware features
which can change between firmware versions. To make it possible to support
different firmware versions with the same driver, convert the flags to firmware
feature flags.
For backwards compatibility support for old ar6004 firmware FW
API 3 or smaller images we forcefully set the feature bits in the driver.
Starting from FW API 5 the firmware image needs to set them.

When receiving an IBSS_JOINED event select the BSS object
based on the {bssid, channel} couple rather than the bssid
only.
With the current approach if another cell having the same
BSSID (but using a different channel) exists then cfg80211
picks up the wrong BSS object.
The result is a mismatching channel configuration between
cfg80211 and the driver, that can lead to any sort of
problem.
The issue can be triggered by having an IBSS sitting on
given channel and then asking the driver to create a new
cell using the same BSSID but with a different frequency.
By passing the channel to cfg80211_get_bss() we can solve
this ambiguity and retrieve/create the correct BSS object.
All the users of cfg80211_ibss_joined() have been changed
accordingly.
Moreover WARN when cfg80211_ibss_joined() gets a NULL
channel as argument and remove a bogus call of the same
function in ath6kl (it does not make sense to call
cfg80211_ibss_joined() with a zero BSSID on ibss-leave).

The scheduled scan matchsets were intended to be a list of filters,
with the found BSS having to pass at least one of them to be passed
to the host. When the RSSI attribute was added, however, this was
broken and currently wpa_supplicant adds that attribute in its own
matchset; however, it doesn't intend that to mean that anything
that passes the RSSI filter should be passed to the host, instead
it wants it to mean that everything needs to also have higher RSSI.
This is semantically problematic because we have a list of filters
like [ SSID1, SSID2, SSID3, RSSI ] with no real indication which
one should be OR'ed and which one AND'ed.
To fix this, move the RSSI filter attribute into each matchset. As
we need to stay backward compatible, treat a matchset with only the
RSSI attribute as a "default RSSI filter" for all other matchsets,
but only if there are other matchsets (an RSSI-only matchset by
itself is still desirable.)
To make driver implementation easier, keep a global min_rssi_thold
for the entire request as well. The only affected driver is ath6kl.
I found this when I looked into the code after Raja Mani submitted
a patch fixing the n_match_sets calculation to disregard the RSSI,
but that patch didn't address the semantic issue.

The station change API isn't being checked properly before
drivers are called, and as a result it is difficult to see
what should be allowed and what not.
In order to comprehensively check the API parameters parse
everything first, and then have the driver call a function
(cfg80211_check_station_change()) with the additionally
information about the kind of station that is being changed;
this allows the function to make better decisions than the
old code could.
While at it, also add a few checks, particularly in mesh
and clarify the TDLS station lifetime in documentation.
To be able to reduce a few checks, ignore any flag set bits
when the mask isn't set, they shouldn't be applied then.

Change nl80211 to support specifying a VHT (or HT)
using the control channel frequency (as before) and
new attributes for the channel width and first and
second center frequency. The old channel type is of
course still supported for HT.
Also change the cfg80211 channel definition struct
to support these by adding the relevant fields to
it (and removing the _type field.)
This also adds new helper functions:
- cfg80211_chandef_create to create a channel def
struct given the control channel and channel type,
- cfg80211_chandef_identical to check if two channel
definitions are identical
- cfg80211_chandef_compatible to check if the given
channel definitions are compatible, and return the
wider of the two
This isn't entirely complete, but that doesn't matter
until we have a driver using it. In particular, it's
missing
- regulatory checks on the usable bandwidth (if that
even makes sense)
- regulatory TX power (database can't deal with it)
- a proper channel compatibility calculation for the
new channel types

Instead of passing a channel pointer and channel type
to all functions and driver methods, pass a new channel
definition struct. Right now, this struct contains just
the control channel and channel type, but for VHT this
will change.
Also, add a small inline cfg80211_get_chandef_type() so
that drivers don't need to use the _type field of the
new structure all the time, which will change.

As mwifiex (and mac80211 in the software case) are the
only drivers actually implementing remain-on-channel
with channel type, userspace can't be relying on it.
This is the case, as it's used only for P2P operations
right now.
Rather than adding a flag to tell userspace whether or
not it can actually rely on it, simplify all the code
by removing the ability to use different channel types.
Leave only the validation of the attribute, so that if
we extend it again later (with the needed capability
flag), it can't break userspace sending invalid data.

The TX power setting is currently per wiphy (hardware
device) but with multi-channel capabilities that doesn't
make much sense any more.
Allow drivers (and mac80211) to advertise support for
per-interface TX power configuration. When the TX power
is configured for the wiphy, the wdev will be NULL and
the driver can still handle that, but when a wdev is
given the TX power can be set only for that wdev now.

Currently AR6004 handles the inactivity timeout resolution
in minutes rather than seconds. So parse the inactivity timeout
to the firmware in minutes. For now we will cleanup the
inactive station entries to the nearest converted minutes
(ex: an inactive time of 70 seconds would take atleast 2 - 3 minutes)

This patch adds support to detect fw error condition by sending
periodic message (heart beat challenge) to firmware. Upon reception
of the message, fw would send a response event to driver. When
there are no reponses from fw for about 5 cmd driver would
trigger the recovery logic assuming that fw has gone into an
error state.
Capable fw will advertise this capability through

is disabled by default, can be enabled through a modparam
(heart_beat_poll). This modparam also confiures the polling

This patch reflects changes in the firmware scheduled scan
implementation to behave better in cases with multiple concurrent vifs.
Major changes:
- scheduled scan filters and state are now programmed per-vif.
- decouple scheduled scan from host sleep.
To maintain graceful failure with old firmwares, a new firmware
capability bit is introduced: ATH6KL_FW_CAPABILITY_SCHED_SCAN_V2.
ath6kl simply won't advertise scheduled scan to cfg80211 if the
SCHED_SCAN_V2 is not supported.
Since firmwares from here on out won't support the previous implicit API
for scheduled scan (set WoW filters and host sleep), bump the firmware
API to protect old drivers.
Unfortunately, due to firmware RAM constraints ath6kl still cannot
expect a scan complete event at the end of a scheduled scan results
cycle, so the sched_scan_timer is retained.

Only WoW filters for the first vif were being set, causing failures to
wake up on any concurrent connected vifs. Handle all per-vif suspend
and resume tasks.
Since cfg80211 issues user wow filters on a per-wiphy basis, set any
custom filters on all connected vifs.
Starting WoW in firmware and setting host sleep mode is still handled on
a global per-phy level. The first vif is always used for bookkeeping
regardless of whether it is connected or not.
WoW is cancelled if no connected vifs are found.
No firmware capability bits or API bump is needed for this patch, as
setting filters for vifs with index > 0 will simply overwrite the index
0 filters in the current implementation. While not correct, this is
identical to the existing behavior.
