Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.
On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.
Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.
As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.
For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".
For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".
This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).

can now be provided to hostapd to allow multiple per-peer and

Fast Session Transfer (FST) is the transfer of a session from a channel
to another channel in a different frequency band. The term "session"
refers to non-physical layer state information kept by a pair of
stations (STAs) that communicate directly (i.e., excludes forwarding).
The FST is implemented in accordance with IEEE Std 802.11ad-2012.
Definitions
* FST interface - an interface for which FST functionality is enabled
* FST group - a bunch of FST interfaces representing single
multi-band STA
* FST peer - a multi-band capable STA connected
* FST module - multi-band operation functionality implemented in
accordance with IEEE Std 802.11ad-2012 (see 10.32
Multi-band operation) as a part of hostapd/wpa_supplicant
* FST manager - an external application that implements custom FST
related logic, using the FST module's interfaces
accessible via CLI or D-Bus
This commit introduces only the FST module. Integration of the FST
module into the hostapd/wpa_supplicant and corresponding CLI/D-Bus
interfaces and FST related tests are covered in separate commits.
FST manager application is out of scope of these commits.
As FST aggregates a few interfaces into FST group, the FST module uses
global CLI for both commands and notifications. It also exposes
alternative non-interface based D-Bus subtree for this purposes.
Configuration and Initialization
* FST functionality can enabled by compilation flag (CONFIG_FST)
* hostapd/wpa_supplicant controlling multiple interfaces are used for
FST
* once enabled by compilation, the FST can be enabled for specific
interfaces in the configuration files
* FST interfaces are aggregated in FST groups (fst_group_id config file
entry), where each FST group:
- represents one multi-band device
- should have two or more FST interfaces in it
* priority (fst_priority config file entry) must be configured for each
FST interface. FST interface with higher priority is the interface FST
will always try to switch to. Thus, for example, for the maximal
throughput, it should be the fastest FST interface in the FST setup.
* default Link Loss Timeout (LLT) value can be configured for each FST
interface (fst_llt config file entry). It represents LLT to be used
by FST when this interface is active.
* FST interfaces advertise the Multi-band capability by including the
Multi-band element in the corresponding frames
FST CLI commands:
* fst list_groups - list FST groups configured.
* fst list_ifaces - list FST interfaces which belong to specific group
* fst iface_peers - list Multi-Band STAs connected to specific interface
* fst list_sessions - list existing FST sessions
* fst session_get - get FST session info
* fst session_add - create FST session object
* fst session_set - set FST session parameters (old_iface, new_iface,
peer_addr, llt)
* fst session_initiate - initiate FST setup
* fst session_respond - respond to FST setup establishemnt attempt by
counterpart
* fst session_transfer - initiate FST switch
* fst session_teardown - tear down FST Setup but leave the session object
for reuse
* fst session_remove - remove FST session object
FST CLI notifications:
* FST-EVENT-PEER - peer state changed (CONNECT/DISCONNECT)
* FST-EVENT-SESSION - FST session level notification with following
sub-events:
- EVENT_FST_SESSION_STATE - FST session state changed
- EVENT_FST_ESTABLISHED - previously initiated FST session became
established
- EVENT_FST_SETUP - new FST session object created due to FST session
negotiation attempt by counterpart
All the FST CLI commands and notifications are also implemented on D-Bus
for wpa_supplicant.
IEEE 802.11 standard compliance
FST module implements FST setup statemachine in compliance with IEEE
802.11ad (P802.11-REVmc/D3.3), as it described in 10.32 Multi-band
operation (see also Figure 10-34 - States of the FST setup protocol).
Thus, for example, the FST module initiates FST switch automatically
when FST setup becomes established with LLT=0 in accordance with
10.32.2.2 Transitioning between states.
At the moment, FST module only supports non-transparent STA-based FST
(see 10.32.1 General).
