      cfg80211: Add global RRM capability · 0c9ca11b
      由 Beni Lev 提交于 
      Today, the supplicant will add the RRM capabilities
Information Element in the association request only if
Quiet period is supported (NL80211_FEATURE_QUIET).

Quiet is one of many RRM features, and there are other RRM
features that are not related to Quiet (e.g. neighbor
report). Therefore, requiring Quiet to enable RRM is too
restrictive.
Some of the features, like neighbor report, can be
supported by user space without any help from the kernel.
Hence adding the RRM capabilities IE to association request
should be the sole user space's decision.
Removing the RRM dependency on Quiet in the driver solves
this problem, but using an old driver with a user space
tool that would not require Quiet feature would be
problematic: the user space would add NL80211_ATTR_USE_RRM
in the association request even if the kernel doesn't
advertize NL80211_FEATURE_QUIET and the association would
be denied by the kernel.

This solution adds a global RRM capability, that tells user
space that it can request RRM capabilities IE publishment
without any specific feature support in the kernel.

      cfg80211: basic support for PBSS network type · 34d50519
      由 Lior David 提交于 
      PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for 11ad devices.

Add support for PBSS by introducing a new PBSS flag attribute.
The PBSS flag is used in the START_AP command to request starting
a PCP instead of an AP, and in the CONNECT command to request
connecting to a PCP instead of an AP.

      cfg80211: Add multiple scan plans for scheduled scan · 3b06d277
      由 Avraham Stern 提交于 
      Add the option to configure multiple 'scan plans' for scheduled scan.
Each 'scan plan' defines the number of scan cycles and the interval
between scans. The scan plans are executed in the order they were
configured. The last scan plan will always run infinitely and thus
defines only the interval between scans.
The maximum number of scan plans supported by the device and the
maximum number of iterations in a single scan plan are advertised
to userspace so it can configure the scan plans appropriately.

When scheduled scan results are received there is no way to know which
scan plan is being currently executed, so there is no way to know when
the next scan iteration will start. This is not a problem, however.
The scan start timestamp is only used for flushing old scan results,
and there is no difference between flushing all results received until
the end of the previous iteration or the start of the current one,
since no results will be received in between.

      nl80211: allow BSS data to include CLOCK_BOOTTIME timestamp · 6e19bc4b
      由 Dmitry Shmidt 提交于 
      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.)

      nl80211: ignore HT/VHT capabilities without QoS/WMM · 496fcc29
      由 Johannes Berg 提交于 
      As HT/VHT depend heavily on QoS/WMM, it's not a good idea to
let userspace add clients that have HT/VHT but not QoS/WMM.
Since it does so in certain cases we've observed (client is
using HT IEs but not QoS/WMM) just ignore the HT/VHT info at
this point and don't pass it down to the drivers which might
unconditionally use it.

      cfg80211: Add API to change the indoor regulatory setting · 05050753
      由 Ilan peer 提交于 
      Previously, the indoor setting configuration assumed that as
long as a station interface is connected, the indoor environment
setting does not change. However, this assumption is problematic
as:

- It is possible that a station interface is connected to a mobile
  AP, e.g., softAP or a P2P GO, where it is possible that both the
  station and the mobile AP move out of the indoor environment making
  the indoor setting invalid. In such a case, user space has no way to
  invalidate the setting.
- A station interface disconnection does not necessarily imply that
  the device is no longer operating in an indoor environment, e.g.,
  it is possible that the station interface is roaming but is still
  stays indoor.

To handle the above, extend the indoor configuration API to allow
user space to indicate a change of indoor settings, and allow it to
indicate weather it controls the indoor setting, such that:

1. If the user space process explicitly indicates that it is going
   to control the indoor setting, do not clear the indoor setting
   internally, unless the socket is released. The user space process
   should use the NL80211_ATTR_SOCKET_OWNER attribute in the command
   to state that it is going to control the indoor setting.
2. Reset the indoor setting when restoring the regulatory settings in
   case it is not owned by a user space process.

Based on the above, a user space tool that continuously monitors the
indoor settings, i.e., tracking power setting, location etc., can
indicate environment changes to the regulatory core.

It should be noted that currently user space is the only provided mechanism
used to hint to the regulatory core over the indoor/outdoor environment --
while the country IEs do have an environment setting this has been completely
ignored by the regulatory core by design for a while now since country IEs
typically can contain bogus data.

      nl80211: prohibit mixing 'any' and regular wowlan triggers · 98fc4386
      由 Johannes Berg 提交于 
      If the device supports waking up on 'any' signal - i.e. it continues
operating as usual and wakes up the host on pretty much anything that
happens, then it makes no sense to also configure the more restricted
WoWLAN mode where the device operates more autonomously but also in a
more restricted fashion.

Currently only cw2100 supports both 'any' and other triggers, but it
seems to be broken as it doesn't configure anything to the device, so
we can't currently get into a situation where both even can correctly
be configured. This is about to change (Intel devices are going to
support both and have different behaviour depending on configuration)
so make sure the conflicting modes cannot be configured.

(It seems that cw2100 advertises 'any' and 'disconnect' as a means of
saying that's what it will always do, but that isn't really the way
this API was meant to be used nor does it actually mean anything as
'any' always implies 'disconnect' already, and the driver doesn't
change device configuration in any way depending on the settings.)

      nl/mac80211: allow zero plink timeout to disable STA expiration · 31f909a2
      由 Masashi Honma 提交于 
      Both wpa_supplicant and mac80211 have and inactivity timer. By default
wpa_supplicant will be timed out in 5 minutes and mac80211's it is 30
minutes. If wpa_supplicant uses a longer timer than mac80211, it will
get unexpected disconnection by mac80211.

Using 0xffffffff instead as the configured value could solve this w/o
changing the code, but due to integer overflow in the expression used
this doesn't work. The expression is:

(current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250)

On 32bit system, the right side would overflow and be a very small
value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large,
causing unexpectedly early disconnections.

Instead allow disabling the inactivity timer to avoid this situation,
by passing the (previously invalid and useless) value 0.
