restore_regulatory_settings() should restore alpha2
as computed in restore_alpha2(), not raw user_alpha2 to
behave as described in the comment just above that code.
This fixes endless loop of calling CRDA for "00" and "97"
countries after resume from suspend on my laptop.
Looks like others had the same problem, too:

Commit eeca9fce1d71 ('cfg80211: Schedule timeout for all CRDA calls')
left behind a superfluous check after it removed some earlier code.
In reg_process_hint, the test of "treatment == REG_REQ_IGNORE ||
treatment == REG_REQ_ALREADY_SET" is superfluous because the code in the
if-then branch is identical to the code after the if statement.
Coverity CID #1295939
I also removed the unnecessary assignment of treatment in this case,
and added a comment reminding any future patch authors to ensure that
treatment is properly assigned before it is used after the switch.

This callback is currently not allowed to sleep, which makes it more
difficult to implement proper driver methods in mac80211 than it has
to be. Instead of doing asynchronous work here in mac80211, make it
possible for the callback to sleep by doing some asynchronous work
in cfg80211. This also enables improvements to other drivers, like
ath6kl, that would like to sleep in this callback.
While at it, also fix the code to call the driver on the implicit
unregistration when an interface is removed, and do that also when
a P2P-Device wdev is destroyed (otherwise we leak the structs.)

Until recently, mac80211 overwrote all the statistics it could
provide when getting called, but it now relies on the struct
having been zeroed by the caller. This was always the case in
nl80211, but wext used a static struct which could even cause
values from one device leak to another.
Using a static struct is OK (as even documented in a comment)
since the whole usage of this function and its return value is
always locked under RTNL. Not clearing the struct for calling
the driver has always been wrong though, since drivers were
free to only fill values they could report, so calling this
for one device and then for another would always have leaked
values from one to the other.
Fix this by initializing the structure in question before the
driver method call.

It was possible for mac80211 to be coerced into an
unexpected flow causing sdata union to become
corrupted. Station pointer was put into
sdata->u.vlan.sta memory location while it was
really master AP's sdata->u.ap.next_beacon. This
led to station entry being later freed as
next_beacon before __sta_info_flush() in
ieee80211_stop_ap() and a subsequent invalid
pointer dereference crash.
The problem was that ieee80211_ptr->use_4addr
wasn't cleared on interface type changes.
This could be reproduced with the following steps:
# host A and host B have just booted; no
# wpa_s/hostapd running; all vifs are down
host A> iw wlan0 set type station
host A> iw wlan0 set 4addr on
host A> printf 'interface=wlan0\nssid=4addrcrash\nchannel=1\nwds_sta=1' > /tmp/hconf
host A> hostapd -B /tmp/conf
host B> iw wlan0 set 4addr on
host B> ifconfig wlan0 up
host B> iw wlan0 connect -w hostAssid
host A> pkill hostapd

When we disconnect from the AP, drivers call cfg80211_disconnect().
This doesn't know whether the disconnection was initiated locally
or by the AP though, which can cause problems with the supplicant,
for example with WPS. This issue obviously doesn't show up with any
mac80211 based driver since mac80211 doesn't call this function.
Fix this by requiring drivers to indicate whether the disconnect is
locally generated or not. I've tried to update the drivers, but may
not have gotten the values correct, and some drivers may currently
not be able to report correct values. In case of doubt I left it at
false, which is the current behaviour.
For libertas, make adjustments as indicated by Dan Williams.

If a P2P GO was allowed on a channel because of the GO concurrent
relaxation, i.e., another station interface was associated to an AP on
the same channel or the same UNII band, and the station interface
disconnected from the AP, allow the following use cases unless the
channel is marked as indoor only and the device is not operating in an
indoor environment:
1. Allow the P2P GO to stay on its current channel. The rationale behind
this is that if the channel or UNII band were allowed by the AP they
could still be used to continue the P2P GO operation, and avoid connection
breakage.
2. Allow another P2P GO to start on the same channel or another channel
that is in the same UNII band as the previous instantiated P2P GO.

wpa_supplicant or authsae handles the mesh peering in user
space, but the plink state is still managed in kernel space.
Currently, there is no implementation by wpa_supplicant or
authsae to block the plink state after it is set to ESTAB.
By applying this patch, we can use the "iw mesh0 station set
<MAC address> plink_action block" to block the peer mesh STA.

This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.
Similar functionality was introduced for the rtnetlink core in
commit 5517750f058e ("net: rtnetlink - make create_link take name_assign_type")

Conflicts:

net/core/sysctl_net_core.c
net/ipv4/inet_diag.c
The be_main.c conflict resolution was really tricky. The conflict
hunks generated by GIT were very unhelpful, to say the least. It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().
So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged. And this worked beautifully.
The inet_diag.c and sysctl_net_core.c conflicts were simple

Previously, the indoor setting configuration assumed that as
long as a station interface is connected, the indoor environment
setting does not change. However, this assumption is problematic
as:
- It is possible that a station interface is connected to a mobile
AP, e.g., softAP or a P2P GO, where it is possible that both the
station and the mobile AP move out of the indoor environment making
the indoor setting invalid. In such a case, user space has no way to
invalidate the setting.
- A station interface disconnection does not necessarily imply that
the device is no longer operating in an indoor environment, e.g.,
it is possible that the station interface is roaming but is still
stays indoor.
To handle the above, extend the indoor configuration API to allow
user space to indicate a change of indoor settings, and allow it to
indicate weather it controls the indoor setting, such that:
1. If the user space process explicitly indicates that it is going
to control the indoor setting, do not clear the indoor setting
internally, unless the socket is released. The user space process
should use the NL80211_ATTR_SOCKET_OWNER attribute in the command
to state that it is going to control the indoor setting.
2. Reset the indoor setting when restoring the regulatory settings in
case it is not owned by a user space process.
Based on the above, a user space tool that continuously monitors the
indoor settings, i.e., tracking power setting, location etc., can
indicate environment changes to the regulatory core.
It should be noted that currently user space is the only provided mechanism
used to hint to the regulatory core over the indoor/outdoor environment --
while the country IEs do have an environment setting this has been completely
ignored by the regulatory core by design for a while now since country IEs
typically can contain bogus data.

If the device supports waking up on 'any' signal - i.e. it continues
operating as usual and wakes up the host on pretty much anything that
happens, then it makes no sense to also configure the more restricted
WoWLAN mode where the device operates more autonomously but also in a
more restricted fashion.
Currently only cw2100 supports both 'any' and other triggers, but it
seems to be broken as it doesn't configure anything to the device, so
we can't currently get into a situation where both even can correctly
be configured. This is about to change (Intel devices are going to
support both and have different behaviour depending on configuration)
so make sure the conflicting modes cannot be configured.
(It seems that cw2100 advertises 'any' and 'disconnect' as a means of
saying that's what it will always do, but that isn't really the way
this API was meant to be used nor does it actually mean anything as
'any' always implies 'disconnect' already, and the driver doesn't
change device configuration in any way depending on the settings.)

802.11ad adds new a network type (PBSS) and changes the capability
field interpretation for the DMG (60G) band.
The same 2 bits that were interpreted as "ESS" and "IBSS" before are
re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid
values are: "IBSS", "PBSS" (new) and "AP".
In order to get the BSS struct for the new PBSS networks, change the
cfg80211_get_bss() function to take a new enum ieee80211_bss_type
argument with the valid network types, as "capa_mask" and "capa_val"
no longer work correctly (the search must be band-aware now.)

When using the wext compatibility code in cfg80211, part of the IEs

Both wpa_supplicant and mac80211 have and inactivity timer. By default
wpa_supplicant will be timed out in 5 minutes and mac80211's it is 30
minutes. If wpa_supplicant uses a longer timer than mac80211, it will
get unexpected disconnection by mac80211.
Using 0xffffffff instead as the configured value could solve this w/o
changing the code, but due to integer overflow in the expression used
this doesn't work. The expression is:
(current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250)
On 32bit system, the right side would overflow and be a very small
value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large,
causing unexpectedly early disconnections.
Instead allow disabling the inactivity timer to avoid this situation,
by passing the (previously invalid and useless) value 0.

When a fully converted cfg80211 driver needs cfg80211-wext for
userspace API purposes, the symbols need not be exported. When
other drivers (orinoco/hermes or ipw2200) are enabled, they do

Make those drivers select a new CFG80211_WEXT_EXPORT Kconfig

only if requested - this saves about 1/2k due to the size of

If monitor flags parsing results in active monitor but that
isn't supported, the already allocated message is leaked.
Fix this by moving the allocation after this check.

We currently add nested members of the NL80211_ATTR_SCAN_FREQUENCIES
as NLA_U32 attributes of type NL80211_ATTR_WIPHY_FREQ in
cfg80211_net_detect_results. However, since there can be an arbitrary number of
frequency results, we should use the loop index of the loop used to add the
frequency results to NL80211_ATTR_SCAN_FREQUENCIES as the type (i.e. nla_type)
for each result attribute, rather than a fixed type.
This change is in line with how nested members are added to
NL80211_ATTR_SCAN_FREQUENCIES in the functions nl80211_send_wowlan_nd and
nl80211_add_scan_req.
