30841f5cde mac80211: drop frames too short for FCS earlier
Instead of dropping such frames only when removing the
monitor info, drop them earlier (keeping the warning)
and simplify removing monitor info. While at it, make
that function return void.

93f56de259 mac80211: Fix clang warning about constant operand in logical operation
When clang detects a non-boolean constant in a logical operation it
generates a 'constant-logical-operand' warning. In
ieee80211_try_rate_control_ops_get() the result of strlen(<const str>)
is used in a logical operation, clang resolves the expression to an
(integer) constant at compile time when clang's builtin strlen function
is used.

Change the condition to check for strlen() > 0 to make the constant
operand boolean and thus avoid the warning.

ed92a9b5d4 mac80211: mesh: drop new node with weak power
On some practical cases, it is useful to drop new node in the distance.
Because mesh metric is calculated with hop count and without RSSI
information, a node far from local peer and near to destination node
could be used as best path.

For example, the nodes are located in linear. Distance of 0 - 1 and
1 - 2 and 2 - 3 is 20meters. 0 to 3 signal is very weak.

    0 --- 1 --- 2 --- 3

Though most robust path from 0 to 3 is 0 -> 1 -> 2 -> 3,
unfortunately, node 0 could recognize node 3 as neighbor. Then node 3
could be next of node 0. This patch aims to avoid such a case.

[Johannes:]
Dropping the node entirely isn't ideal, but at least with encryption
there will be a limit on # of keys the hardware can deal with, and
there might also be a limit on the number of stations it supports.

e8e4f5280d mac80211: reject/clear user rate mask if not usable
If the user rate mask results in no (basic) rates being usable,
clear it. Also, if we're already operating when it's set, reject
it instead.

Technically, selecting basic rates as the criterion is a bit too
restrictive, but calculating the usable rates over all stations
(e.g. in AP mode) is harder, and all stations must support the
basic rates. Similarly, in client mode, the basic rates will be
used anyway for control frames.

This fixes the "no supported rates (...) in rate_mask ..." warning
that occurs on TX when you've selected a rate mask that's not
compatible with the connection (e.g. an AP that enables only the
rates 36, 48, 54 and you've selected only 6, 9, 12.)

8976672736 cfg80211: Share Channel DFS state across wiphys of same DFS domain
Sharing DFS channel state across multiple wiphys (radios) could
be useful with multiple radios on the system. When one radio
completes CAC and markes the channel available another radio
can use this information and start beaconing without really doing
CAC.

Whenever there is a state change in dfs channel associated to
a particular wiphy the the same state change is propagated to
other wiphys having the same DFS reg domain configuration.
Also when a new wiphy is created the dfs channel state of
other existing wiphys of same DFS domain is copied.

For non-ETSI regulatory domain, CAC result on DFS channel
may not be valid once moving out of that channel (as done
during remain-on-channel, scannning and off-channel tx).
Running CAC on an operating DFS channel after every off-channel
operation will only add complexity and disturb the current
link. Better do not allow any off-channel switch from a DFS
operating channel in non-ETSI domain.

b35a51c7dd cfg80211: Make pre-CAC results valid only for ETSI domain
DFS requirement for ETSI domain (section 4.7.1.4 in
ETSI EN 301 893 V1.8.1) is the only one which explicitly
states that once DFS channel is marked as available afer
the CAC, this channel will remain in available state even
moving to a different operating channel. But the same is
not explicitly stated in FCC DFS requirement. Also, Pre-CAC
requriements are not explicitly mentioned in FCC requirement.
Current implementation in keeping DFS channel in available
state is same as described in ETSI domain.

For non-ETSI DFS domain, this patch gives a grace period of 2 seconds
since the completion of successful CAC before moving the channel's
DFS state to 'usable' from 'available' state. The same grace period
is checked against the channel's dfs_state_entered timestamp while
deciding if a DFS channel is available for operation. There is a new
radar event, NL80211_RADAR_PRE_CAC_EXPIRED, reported when DFS channel
is moved from available to usable state after the grace period. Also
make sure the DFS channel state is reset to usable once the beaconing
operation on that channel is brought down (like stop_ap, leave_ibss
and leave_mesh) in non-ETSI domain.

4a4b816950 cfg80211: Accept multiple RSSI thresholds for CQM
Change the SET CQM command's RSSI threshold attribute to accept any
number of thresholds as a sorted array.  The API should be backwards
compatible so that if one s32 threshold value is passed, the old
mechanism is enabled.  The netlink event generated is the same in both
cases.

cfg80211 handles an arbitrary number of RSSI thresholds but drivers have
to provide a method (set_cqm_rssi_range_config) that configures a range
set by a high and a low value.  Drivers have to call back when the RSSI
goes out of that range and there's no additional event for each time the
range is reconfigured as there was with the current one-threshold API.

This method doesn't have a hysteresis parameter because there's no
benefit to the cfg80211 code from having the hysteresis be handled by
hardware/driver in terms of the number of wakeups.  At the same time
it would likely be less consistent between drivers if offloaded or
done in the drivers.

91aff98b79 Staging/IIO driver fixes for 4.11-rc1
Here are a few small staging and IIO driver fixes for issues that showed
 up after the big set if changes you merged last week.
 
 Nothing major, just small bugs resolved in some IIO drivers, a lustre
 allocation fix, and some RaspberryPi driver fixes for reported problems,
 as well as a MAINTAINERS entry update.
 
 All of these have been in linux-next for a week with no reported issues.

This is the set of stuff that didn't quite make the initial pull and a
 set of fixes for stuff which did.  The new stuff is basically lpfc
 (nvme), qedi and aacraid.  The fixes cover a lot of previously
 submitted stuff, the most important of which probably covers some of
 the failing irq vectors allocation and other fallout from having the
 SCSI command allocated as part of the block allocation functions.

Netfilter fixes for net

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Missing check for full sock in ip_route_me_harder(), from
   Florian Westphal.

2) Incorrect sip helper structure initilization that breaks it when
   several ports are used, from Christophe Leroy.

3) Fix incorrect assumption when looking up for matching with adjacent
   intervals in the nft_set_rbtree.

4) Fix broken netlink event error reporting in nf_tables that results
   in misleading ESRCH errors propagated to userspace listeners.

Pull libnvdimm fixes from Dan Williams:
 "A fix and regression test case for nvdimm namespace label
  compatibility.

  Details:

   - An "nvdimm namespace label" is metadata on an nvdimm that
     provisions dimm capacity into a "namespace" that can host a block
     device / dax-filesytem, or a device-dax character device.

     A namespace is an object that other operating environment and
     platform firmware needs to comprehend for capabilities like booting
     from an nvdimm.

     The label metadata contains a checksum that Linux was not
     calculating correctly leading to other environments rejecting the
     Linux label.

   These have received a build success notification from the kbuild
   robot, and a positive test result from Nick who reported the problem"
