The "chandef->center_freq1" variable is a u32 but "freq" is a u16 so we
are truncating away the high bits. I noticed this bug because in commit
9cf0a0b4b6 ("cfg80211: Add support for 60GHz band channels 5 and 6")
we made "freq <= 56160 + 2160 * 6" a valid requency when before it was
only "freq <= 56160 + 2160 * 4" that was valid. It introduces a static
checker warning:
net/wireless/util.c:1571 ieee80211_chandef_to_operating_class()
warn: always true condition '(freq <= 56160 + 2160 * 6) => (0-u16max <= 69120)'

When REGULATORY_COUNTRY_IE_IGNORE is set, __reg_process_hint_country_ie()
ignores the country code change request from __cfg80211_connect_result()
via regulatory_hint_country_ie().
After Disconnect, similar to above, country code should not be reset to
world when country IE ignore is set. But this is violated and restore of
regulatory settings is invoked by cfg80211_disconnect_work via
regulatory_hint_disconnect().
To address this, avoid regulatory restore from regulatory_hint_disconnect()
when COUNTRY_IE_IGNORE is set.
Note: Currently, restore_regulatory_settings() takes care of clearing
beacon hints. But in the proposed change, regulatory restore is avoided.
Therefore, explicitly clear beacon hints when DISABLE_BEACON_HINTS

each channel anyway.

The current implementation of cfg80211_rx_control_port assumed that the
caller could provide a contiguous region of memory for the control port
frame to be sent up to userspace. Unfortunately, many drivers produce
non-linear skbs, especially for data frames. This resulted in userspace
getting notified of control port frames with correct metadata (from
address, port, etc) yet garbage / nonsense contents, resulting in bad
handshakes, disconnections, etc.
mac80211 linearizes skbs containing management frames. But it didn't
seem worthwhile to do this for control port frames. Thus the signature
of cfg80211_rx_control_port was changed to take the skb directly.
nl80211 then takes care of obtaining control port frame data directly
from the (linear | non-linear) skb.
The caller is still responsible for freeing the skb,
cfg80211_rx_control_port does not take ownership of it.

The BIT macro uses unsigned long which some architectures handle as 32 bit
and therefore might cause macro's shift to overflow when used on a value
equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards).
Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with all NL80211_STA_INFO_* attribute types instead of BIT
to prevent future possible bugs when one will use BIT macro for higher
attributes by mistake.
This commit cleans up all usages of BIT macro with the above field
in cfg80211 by changing it to BIT_ULL instead. In addition, there are
some places which don't use BIT nor BIT_ULL macros so align those as well.

The cfg80211 layer uses get_seconds() to read the current time
in its supend handling. This function is deprecated because of the 32-bit
time_t overflow, and it can cause unexpected behavior when the time
changes due to settimeofday() calls or leap second updates.
In many cases, we want to use monotonic time instead, however cfg80211
explicitly tracks the time spent in suspend, so this changes the
driver over to use ktime_get_boottime_seconds(), which is slightly
slower, but not used in a fastpath here.

Commit 9757235f45, "nl80211: correct checks for
NL80211_MESHCONF_HT_OPMODE value") relaxed the range for the HT
operation field in meshconf, while also adding checks requiring
the non-greenfield and non-ht-sta bits to be set in certain
circumstances. The latter bit is actually reserved for mesh BSSes
according to Table 9-168 in 802.11-2016, so in fact it should not
be set.
wpa_supplicant sets these bits because the mesh and AP code share
the same implementation, but authsae does not. As a result, some
meshconf updates from authsae which set only the NONHT_MIXED
protection bits were being rejected.
In order to avoid breaking userspace by changing the rules again,
simply accept the values with or without the bits set, and mask
off the reserved bit to match the spec.
While in here, update the 802.11-2012 reference to 802.11-2016.

Most of the implementations behind cfg80211_get_station will not initialize
sinfo to zero before manipulating it. For example, the member "filled",
which indicates the filled in parts of this struct, is often only modified
by enabling certain bits in the bitfield while keeping the remaining bits
in their original state. A caller without a preinitialized sinfo.filled can
then no longer decide which parts of sinfo were filled in by
cfg80211_get_station (or actually the underlying implementations).
cfg80211_get_station must therefore take care that sinfo is initialized to
zero. Otherwise, the caller may tries to read information which was not
filled in and which must therefore also be considered uninitialized. In
batadv_v_elp_get_throughput's case, an invalid "random" expected throughput
may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may
switch to non-optimal neighbors for certain destinations.

Reject NL80211_CMD_DISCONNECT, NL80211_CMD_DISASSOCIATE,
NL80211_CMD_DEAUTHENTICATE and NL80211_CMD_ASSOCIATE commands
from clients other than the connection owner set in the connect,
authenticate or associate commands, if it was set.
The main point of this check is to prevent chaos when two processes
try to use nl80211 at the same time, it's not a security measure.
The same thing should possibly be done for JOIN_IBSS/LEAVE_IBSS and
START_AP/STOP_AP.

Use NL80211_CMD_UPDATE_CONNECT_PARAMS to update new ERP information,
Association IEs and the Authentication type to driver / firmware which
will be used in subsequent roamings.

Some drivers may call this function when regdb is not initialized yet,
so we need to make sure regdb is valid before trying to access it.
Make sure regdb is initialized before trying to access it in
reg_query_regdb_wmm() and query_regdb().

Arend's previous patch made the sinfo structure smaller
again by to dynamically allocating the per-tid stats
only when needed. Thus, revert to stack allocation for
the struct to simplify the code.
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
With the addition of TXQ stats in the per-tid statistics the struct
station_info grew significantly. This resulted in stack size warnings
due to the structure itself being above the limit for the warnings.
Add an allocation function that those who want to provide per-tid
stats should use to allocate the tid array, i.e.
struct station_info::pertid.
