      mac80211: Turn AQL into an NL80211_EXT_FEATURE · 911bde0f
      由 Toke Høiland-Jørgensen 提交于 
      Instead of just having an airtime flag in debugfs, turn AQL into a proper
NL80211_EXT_FEATURE, so drivers can turn it on when they are ready, and so
we also expose the presence of the feature to userspace.

This also has the effect of flipping the default, so drivers have to opt in
to using AQL instead of getting it by default with TXQs. To keep
functionality the same as pre-patch, we set this feature for ath10k (which
is where it is needed the most).

While we're at it, split out the debugfs interface so AQL gets its own
per-station debugfs file instead of using the 'airtime' file.

[Johannes:]
This effectively disables AQL for iwlwifi, where it fixes a number of
issues:
 * TSO in iwlwifi is causing underflows and associated warnings in AQL
 * HE (802.11ax) rates aren't reported properly so at HE rates, AQL could
   never have a valid estimate (it'd use 6 Mbps instead of up to 2400!)

      cfg80211/nl80211: Offload OWE processing to user space in AP mode · cb74e977
      由 Sunil Dutt 提交于 
      This interface allows the host driver to offload OWE processing
to user space. This intends to support OWE (Opportunistic Wireless
Encryption) AKM by the drivers that implement SME but rely on the
user space for the cryptographic/OWE processing in AP mode. Such
drivers are not capable of processing/deriving the DH IE.

A new NL80211 command - NL80211_CMD_UPDATE_OWE_INFO is introduced
to send the request/event between the host driver and user space.

Driver shall provide the OWE info (MAC address and DH IE) of
the peer to user space for cryptographic processing of the DH IE
through the event. Accordingly, the user space shall update the
OWE info/DH IE to the driver.

Following is the sequence in AP mode for OWE authentication.

Driver passes the OWE info obtained from the peer in the
Association Request to the user space through the event
cfg80211_update_owe_info_event. User space shall process the
OWE info received and generate new OWE info. This OWE info is
passed to the driver through NL80211_CMD_UPDATE_OWE_INFO
request. Driver eventually uses this OWE info to send the
Association Response to the peer.

This OWE info in the command interface carries the IEs that include
PMKID of the peer if the PMKSA is still valid or an updated DH IE
for generating a new PMKSA with the peer.

      nl80211/cfg80211: Specify band specific min RSSI thresholds with sched scan · 1e1b11b6
      由 vamsi krishna 提交于 
      This commit adds the support to specify the RSSI thresholds per
band for each match set. This enhances the current behavior which
specifies a single rssi_threshold across all the bands by
introducing the rssi_threshold_per_band. These per band rssi
thresholds are referred through NL80211_BAND_* (enum nl80211_band)
variables  as attribute types. Such attributes/values per each
band are nested through NL80211_ATTR_SCHED_SCAN_MIN_RSSI.
These band specific rssi thresholds shall take precedence over
the current rssi_thold per match set.
Drivers indicate this support through
%NL80211_EXT_FEATURE_SCHED_SCAN_BAND_SPECIFIC_RSSI_THOLD.
These per band rssi attributes/values does not specify
"default RSSI filter" as done by
NL80211_SCHED_SCAN_MATCH_ATTR_RSSI to stay backward compatible.
That said, these per band rssi values have to be specified for
the corresponding matchset.

      nl80211: Allow set/del pmksa operations for AP · 6c900360
      由 Liangwei Dong 提交于 
      Host drivers may offload authentication to the user space
through the commit ("cfg80211: Authentication offload to
user space in AP mode").

This interface can be used to implement SAE by having the
userspace do authentication/PMKID key derivation and driver
handle the association.

A step ahead, this interface can get further optimized if the
PMKID is passed to the host driver and also have it respond to
the association request by the STA on a valid PMKID.

This commit enables the userspace to pass the PMKID to the host
drivers through the set/del pmksa operations in AP mode.

Set/Del pmksa is now restricted to STA/P2P client mode only and
thus the drivers might not expect them in any other(AP) mode.

This commit also introduces a feature flag
NL80211_EXT_FEATURE_AP_PMKSA_CACHING (johannes: renamed) to
maintain the backward compatibility of such an expectation by
the host drivers. These operations are allowed in AP mode only
when the drivers advertize the capability through this flag.

      cfg80211: Authentication offload to user space in AP mode · fe494370
      由 Srinivas Dasari 提交于 
      commit 40cbfa90 ("cfg80211/nl80211: Optional authentication
offload to userspace")' introduced authentication offload to user
space by the host drivers in station mode. This commit extends
the same for the AP mode too.

Extend NL80211_ATTR_EXTERNAL_AUTH_SUPPORT to also claim the
support of external authentication from the user space in AP mode.
A new flag parameter is introduced in cfg80211_ap_settings to
intend the same while "start ap".

Host driver to use NL80211_CMD_FRAME interface to transmit and
receive the authentication frames to / from the user space.

Host driver to indicate the flag NL80211_RXMGMT_FLAG_EXTERNAL_AUTH
while sending the authentication frame to the user space. This
intends to the user space that the driver wishes it to process
the authentication frame for certain protocols, though it had
initially advertised the support for SME functionality.

User space shall accordingly do the authentication and indicate
its final status through the command NL80211_CMD_EXTERNAL_AUTH.
Allow the command even if userspace doesn't include the attribute
NL80211_ATTR_SSID for AP interface.

Host driver shall continue with the association sequence and
indicate the STA connection status through cfg80211_new_sta.

To facilitate the host drivers in AP mode for matching the pmkid
by the stations during the association, NL80211_CMD_EXTERNAL_AUTH
is also enhanced to include the pmkid to drivers after
the authentication.
This pmkid can also be used in the STA mode to include in the
association request.

Also modify nl80211_external_auth to not mandate SSID in AP mode.

      cfg80211: Allow drivers to advertise supported AKM suites · ab4dfa20
      由 Veerendranath Jakkam 提交于 
      There was no such capability advertisement from the driver and thus the
current user space has to assume the driver to support all the AKMs. While
that may be the case with some drivers (e.g., mac80211-based ones), there
are cfg80211-based drivers that implement SME and have constraints on
which AKMs can be supported (e.g., such drivers may need an update to
support SAE AKM using NL80211_CMD_EXTERNAL_AUTH). Allow such drivers to
advertise the exact set of supported AKMs so that user space tools can
determine what network profile options should be allowed to be configured.
