Merge remote-tracking branch 'net-next/master' into mac80211-next

2019-02-22T12:48:13+00:00

Merge net-next to resolve a conflict and to get the mac80211
rhashtable fixes so further patches can be applied on top.

cfg80211: Move Multiple BSS info to struct cfg80211_bss to be visible

2019-02-08T12:51:50+00:00

Previously the transmitted BSS and the non-trasmitted BSS list were
defined in struct cfg80211_internal_bss. Move them to struct cfg80211_bss
since mac80211 needs this info.

cfg80211: Properly track transmitting and non-transmitting BSS

2019-02-08T12:51:50+00:00

When holding data of the non-transmitting BSS, we need to keep the
transmitting BSS data on. Otherwise it will be released, and release
the non-transmitting BSS with it.

cfg80211: Parsing of Multiple BSSID information in scanning

2019-02-08T12:51:50+00:00

This extends cfg80211 BSS table processing to be able to parse Multiple
BSSID element from Beacon and Probe Response frames and to update the
BSS profiles in internal database for non-transmitted BSSs.

cfg80211: call disconnect_wk when AP stops

2019-02-01T10:12:50+00:00

Since we now prevent regulatory restore during STA disconnect
if concurrent AP interfaces are active, we need to reschedule
this check when the AP state changes. This fixes never doing
a restore when an AP is the last interface to stop. Or to put
it another way: we need to re-check after anything we check
here changes.

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

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.)

cfg80211: combine duplicate wdev init code

There's a bit of duplicated code to initialize a wdev, pull it out

cfg80211: track time using boottime

2018-06-29T07:49:28+00:00

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.
