cfg80211: clarify LCI/civic location documentation

2018-12-18T12:15:04+00:00

The older code and current userspace assumed that this data
is the content of the Measurement Report element, starting
with the Measurement Token. Clarify this in the documentation.

wireless: FTM: fix kernel-doc "cannot understand" warnings

2018-12-18T12:14:23+00:00

Fix kernel-doc warnings in FTM due to missing "struct" keyword.

Fixes 109 warnings from :
../include/net/cfg80211.h:2838: warning: cannot understand function prototype: 'struct cfg80211_ftm_responder_stats '

and fixes 88 warnings from :
../include/net/mac80211.h:477: warning: cannot understand function prototype: 'struct ieee80211_ftm_responder_params '

Fixes: 81e54d08d9d8 ("cfg80211: support FTM responder configuration/statistics")
Fixes: bc847970f432 ("mac80211: support FTM responder configuration/statistics")

{nl,mac}80211: add rssi to mesh candidates

2018-11-09T10:41:20+00:00

When peering is in userspace, some implementations may want to control
which peers are accepted based on RSSI in addition to the information
elements being sent today.  Add signal level so that info is available
to clients.

{nl,mac}80211: add dot11MeshConnectedToMeshGate to meshconf

2018-11-09T10:39:44+00:00

When userspace is controlling mesh routing, it may have better
knowledge about whether a mesh STA is connected to a mesh
gate than the kernel mpath table.  Add dot11MeshConnectedToMeshGate
to the mesh config so that such applications can explicitly
signal that a mesh STA is connected to a gate, which will then
be advertised in the beacon.

{nl,mac}80211: report gate connectivity in station info

2018-11-09T10:38:29+00:00

Capture the current state of gate connectivity from the mesh
formation field in mesh config whenever we receive a beacon,
and report that via GET_STATION.  This allows applications
doing mesh peering in userspace to make peering decisions
based on peers' current upstream connectivity.

cfg80211: add peer measurement with FTM initiator API

2018-11-09T10:20:13+00:00

Add a new "peer measurement" API, that can be used to measure
certain things related to a peer. Right now, only implement
FTM (flight time measurement) over it, but the idea is that
it'll be extensible to also support measuring the necessary
things to calculate e.g. angle-of-arrival for WiGig.

The API is structured to have a generic list of peers and
channels to measure with/on, and then for each of those a
set of measurements (again, only FTM right now) to perform.

Results are sent to the requesting socket, including a final
complete message.

Closing the controlling netlink socket will abort a running
measurement.

v3:
 - add a bit to report "final" for partial results
 - remove list keeping etc. and just unicast out the results
   to the requester (big code reduction ...)
 - also send complete message unicast, and as a result
   remove the multicast group
 - separate out struct cfg80211_pmsr_ftm_request_peer
   from struct cfg80211_pmsr_request_peer
 - document timeout == 0 if no timeout
 - disallow setting timeout nl80211 attribute to 0,
   must not include attribute for no timeout
 - make MAC address randomization optional
 - change num bursts exponent default to 0 (1 burst, rather
   rather than the old default of 15==don't care)

v4:
 - clarify NL80211_ATTR_TIMEOUT documentation

v5:
 - remove unnecessary nl80211 multicast/family changes
 - remove partial results bit/flag, final is sufficient
 - add max_bursts_exponent, max_ftms_per_burst to capability
 - rename "frames per burst" -> "FTMs per burst"

v6:
 - rename cfg80211_pmsr_free_wdev() to cfg80211_pmsr_wdev_down()
   and call it in leave, so the device can't go down with any
   pending measurements

v7:
 - wording fixes (Lior)
 - fix ftm.max_bursts_exponent to allow having the limit of 0 (Lior)

v8:
 - copyright statements
 - minor coding style fixes
 - fix error path leak

nl80211: Add per peer statistics to compute FCS error rate

2018-10-12T10:56:34+00:00

Add support for drivers to report the total number of MPDUs received
and the number of MPDUs received with an FCS error from a specific
peer. These counters will be incremented only when the TA of the
frame matches the MAC address of the peer irrespective of FCS
error.

It should be noted that the TA field in the frame might be corrupted
when there is an FCS error and TA matching logic would fail in such
cases. Hence, FCS error counter might not be fully accurate, but it can
provide help in detecting bad RX links in significant number of cases.
This FCS error counter without full accuracy can be used, e.g., to
trigger a kick-out of a connected client with a bad link in AP mode to
force such a client to roam to another AP.

cfg80211: move cookie_counter out of wiphy

2018-10-02T07:58:36+00:00

There's no reason for drivers to be able to access the
cfg80211 internal cookie counter; move it out of the
wiphy into the rdev structure.

While at it, also make it never assign 0 as a cookie
(we consider that invalid in some places), and warn if
we manage to do that for some reason (wrapping is not
likely to happen with a u64.)
