cd6c65981e nl80211: refactor valid channel type check
There are four instances in nl80211 of getting the
channel type from the attribute and validating it,
refactor those.

ac422d3cc2 wireless: Convert compare_ether_addr to ether_addr_equal
Use the new bool function ether_addr_equal to add

This patch introduces a new mesh configuration parameter "ht_opmode" and will
allow user to check the current HT protection mode selected. Users could
configure the protection mode by the command "iw mesh_iface set mesh_param
mesh_ht_protection_mode=2". The default protection mode of mesh is set to
non-HT mixed mode.

ef9456a85d cfg80211: fix BSS comparison
Since the BSS table is organized in a RB tree, the BSSs need to be
comparable. This means that we must define a < and > operator to
the BSS object.
compare_ethr_addr isn't enough since it returns only a binary value.

Since Felix's

cfg80211: use compare_ether_addr on MAC addresses instead of memcmp

    Because of the constant size and guaranteed 16 bit alignment, the inline
    compare_ether_addr function is much cheaper than calling memcmp.

The BSS table is corrupted: rb_find_bss can't find the bss.
As a result BSSes are duplicated in the BSS table, and we get stuck
while probing an AP before associating (in STA mode).

Begin enforcing combinations in cfg80211 so that users
can rely on the information reported about a device.

6d52563f2b cfg80211/mac80211: enable proper device_set_wakeup_enable handling
In WoWLAN, we only get the triggers when we actually get
to suspend. As a consequence, drivers currently don't
know that the device should enable wakeup. However, the
device_set_wakeup_enable() API is intended to be called
when the wakeup is enabled, not later when needed.

80007efeff cfg80211: warn if db.txt is empty with CONFIG_CFG80211_INTERNAL_REGDB
It has happened twice now where elaborate troubleshooting has
undergone on systems where CONFIG_CFG80211_INTERNAL_REGDB [0]
has been set but yet net/wireless/db.txt was not updated.

Despite the documentation on this it seems system integrators could
use some more help with this, so throw out a kernel warning at boot time
when their database is empty.

This does mean that the error-prone system integrator won't likely
realize the issue until they boot the machine but -- it does not seem
to make sense to enable a build bug breaking random build testing.

234e340582 simple_open: automatically convert to simple_open()
Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op.  This leads to a
proliferation of the default_open() implementation across the entire

Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().

This replacement was done with the following semantic patch:

1b658f118b cfg80211: Add an attribute to set inactivity timeout in AP mode
This patch adds an attribute, NL80211_ATTR_INACTIVITY_TIMEOUT,
to set the inactivity timeout which can be used to remove the
station in AP mode. This can be passed in NL80211_CMD_START_AP
and used by the drivers which have AP MLME in firmware but
don't support get_station() properly. To disable inactivity
timer in userspace, wpa_s for example, there is a new flag,
NL80211_FEATURE_INACTIVITY_TIMER, in nl80211_feature_flags
through which drivers can register their capability to use
the inactivity timeout to free the stations.

5533513784 {nl,cfg,mac}80211: Implement RSSI threshold for mesh peering
Mesh peer links are established only if average rssi of the peer
candidate satisfies the threshold. This is not in 802.11s specification
but was requested by David Fulgham, an open80211s user. This is a way to avoid
marginal peer links with stations that are barely within range.

This patch adds a new mesh configuration parameter, mesh_rssi_threshold. This
feature is supported only for hardwares that report signal in dBm.

63c9c5e77c cfg80211: remove cookies from callbacks
In "cfg80211: no cookies in cfg80211_send_XXX()"
Holger Schurig removed the cookies in the calls
from mac80211 to cfg80211, but the ones in the
other direction were left in. Remove them now.

8860020e0b cfg80211: restructure AP/GO mode API
The AP/GO mode API isn't very clearly defined, it
has "set beacon" and "new beacon" etc.

Modify the API to the following:
 * start AP -- all settings
 * change beacon -- new beacon data
 * stop AP -- stop AP mode operation

This also reflects in the nl80211 API, rename
the commands there correspondingly (but keep
the old names for compatibility.)

Overall, this makes it much clearer what's going
on in the API.

Kalle developed the ath6kl changes, I created
the rest of the patch.

If the IBSS network is RSN-protected, let userspace authorize the stations
instead of adding them as AUTHORIZED by default.

old version of cfg80211_ref_bss() since it's

95de817b90 cfg80211: stop tracking authenticated state
To track authenticated state seems to have been
a design mistake in cfg80211. It is possible to
have out of band authentication (FT), tracking
multiple authentications caused more problems
than it ever helped, and the implementation in
mac80211 is too complex.

Remove all this complexity, and let userspace
do whatever it wants to, mac80211 can deal with
that just fine. Association is still tracked of
course, but authentication no longer is. Local
auth state changes are thus no longer of value,
so ignore them completely.

This will also help implement SAE -- asking the
driver to do an authentication is now almost
equivalent to sending an authentication frame,
with the exception of shared key authentication
which is still handled completely.
