nl80211: allow BSS data to include CLOCK_BOOTTIME timestamp

2015-10-13T08:32:17+00:00

For location and connectivity services, userspace would often like
to know the time when the BSS was last seen. The current "last seen"
value is calculated in a way that makes it less useful, especially
if the system suspended in the meantime.

Add the ability for the driver to report a real CLOCK_BOOTTIME stamp
that can then be reported to userspace (if present).

Drivers wishing to use this must be converted to the new API to call
cfg80211_inform_bss_data() or cfg80211_inform_bss_frame_data(). They
need to ensure the reported value is accurate enough even when the
frame might have been buffered in the device (e.g. firmware.)

cfg80211: use RTNL locked reg_can_beacon for IR-relaxation

2015-07-17T13:02:02+00:00

The RTNL is required to check for IR-relaxation conditions that allow
more channels to beacon. Export an RTNL locked version of reg_can_beacon
and use it where possible in AP/STA interface type flows, where
IR-relaxation may be applicable.

====================
Lots of updates for net-next; along with the usual flurry
of small fixes, cleanups and internal features we have:
 * VHT support for TDLS and IBSS (conditional on drivers though)
 * first TX performance improvements (the biggest will come later)
 * many suspend/resume (race) fixes
 * name_assign_type support from Tom Gundersen

cfg80211: add vlan to station add/change tracing

2015-03-20T18:56:41+00:00

This helps debug issues with VLAN modifications that are otherwise
not really visible in any tracing/debugging.

cfg80211: add bss_type and privacy arguments in cfg80211_get_bss()

2015-03-03T14:56:01+00:00

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.)

The remaining bits in "capa_mask" and "capa_val" are used only for
privacy matching so replace those two with a privacy enum as well.

cfg80211: add scan time to survey data

2015-01-08T14:27:58+00:00

Add the time spent scanning to the survey data so it can be
reported by drivers that collect such information.

cfg80211: remove "channel" from survey names

2015-01-08T14:27:52+00:00

All of the survey data is (currently) per channel anyway,
so having the word "channel" in the name does nothing. In
the next patch I'll introduce global data to the survey,
where the word "channel" is actually confusing.

cfg80211: introduce TDLS channel switch commands

2014-11-19T17:45:12+00:00

Introduce commands to initiate and cancel TDLS channel-switching. Once
TDLS channel-switching is started, the lower level driver is responsible
for continually initiating channel-switch operations and returning to
the base (AP) channel to listen for beacons from time to time.

Upon cancellation of the channel-switch all communication between the
relevant TDLS peers will continue on the base channel.

cfg80211: add channel switch started notification

2014-11-10T09:20:14+00:00

Add a new NL80211_CH_SWITCH_STARTED_NOTIFY message that can be sent to
the userspace when a channel switch process has started.  This allows
userspace to take action, for instance, by requesting other interfaces
to switch channel as necessary.

This patch introduces a function that allows the drivers to send this
notification.  It should be used when the driver starts processing a
channel switch initiated by a remote device (eg. when a STA receives a
CSA from the AP) and when it successfully starts a userspace-triggered
channel switch (eg. when hostapd triggers a channel swith in the AP).
