af8bc24da3 MBO: Add support for transition reject reason code
Add support for rejecting a BSS transition request using MBO reject
reason codes. A candidate is selected or rejected based on whether it is
found acceptable by both wpa_supplicant and the driver. Also accept any
candidate meeting a certain threshold if disassoc imminent is set in BTM
Request frame.

88a447556e Fix SELECT_NETWORK freq parameter
This functionality was originally added in commit
204c9ac4ee ('Extend select_network command
with freq= to reduce scan time') re-using wpa_s->manual_scan_freqs and
MANUAL_SCAN_REQ. That got broken when commit
35d403096e ('Set NORMAL_SCAN_REQ on
SELECT_NETWORK/ENABLE_NETWORK') started overriding wpa_s->scan_req for
SELECT_NETWORK.

Fix this by adding a new scan frequency list specifically for
SELECT_NETWORK so that this does not need to depend on any specific
wpa_s->scan_req value.

The below commands can be used to configure relative RSSI parameters
SET relative_rssi <disable|rssi_value>
	disable - to disable the feature
	rssi_value - amount of relative RSSI in dB
SET relative_band_adjust <band:adjust_value>
	band - "2G" or "5G" for 2.4 GHz or 5 GHz respectively

4d77d80edd mesh: Add MESH_PMKSA_GET/ADD commands
These commnds are mesh version of PMKSA_GET/ADD commands. So the usage
and security risk is similar to them. Refer to
commit 3459381dd2 ('External persistent
storage for PMKSA cache entries') also.

The MESH_PMKSA_GET command requires peer MAC address or "any" as an
argument and outputs appropriate stored PMKSA cache. And the
MESH_PMKSA_ADD command receives an output of MESH_PMKSA_GET and re-store
the PMKSA cache into wpa_supplicant. By using re-stored PMKSA cache,
wpa_supplicant can skip commit message creation which can use
significant CPU resources.

The output of the MESH_PMKSA_GET command uses the following format:
<BSSID> <PMKID> <PMK> <expiration in seconds>

The example of MESH_PMKSA_ADD command is this.
MESH_PMKSA_ADD 02:00:00:00:03:00 231dc1c9fa2eed0354ea49e8ff2cc2dc cb0f6c9cab358a8146488566ca155421ab4f3ea4a6de2120050c149b797018fe 42930

This functionality is disabled by default and can be enabled with
CONFIG_PMKSA_CACHE_EXTERNAL=y build configuration option.

6e374bd44d Ignore scan results from ongoing scan when FLUSH command is issued
This makes wpa_supplicant behavior more consistent with FLUSH command to
clear all state. Previously, it was possible for an ongoing scan to be
aborted when the FLUSH command is issued and the scan results from that
aborted scan would still be processed and that would update the BSS
table which was supposed to cleared by the FLUSH command.

This could result in hwsim test case failures due to unexpected BSS
table entries being present after the FLUSH command.

bf88401d23 Add support to abort vendor scan
This commit enhances the existing implementation of abort scan to also
abort concurrent active vendor scans. This is achieved by passing the
the scan_cookie to the driver interface with the intention to abort
the specific scan request. This scan_cookie is returned from the driver
interface when the scan request is scheduled.

This scan_cookie is 0 if the scan is triggered through the upstream
cfg80211 interface. Thus, the scan_cookie is used to determine whether
to abort the cfg80211 or vendor scan request.

Also, the previous implementation of relying on scan_work/p2p_scan_work
for the active work to trigger the abort scan is enhanced to check for
the started state of either of these work operations. This should also
help to abort the concurrent active scan/p2p-scan operations.

7b4bbb9f94 binder: Add binder skeletal code for Android
Create the skeletal binder interface for wpa_supplicant. The interface
hierarchy is based off the existing dbus
interface(https://w1.fi/wpa_supplicant/devel/dbus.html).

Since we use libbinder, the binder interface codebase needs to be
written in C++ and can only be compiled on Android platform for now.

The aidl files define binder RPC interfaces. The Android build system
generates the corresponding C++ interface classes which needs to be
implemented by the server process.

The clients can obtain a reference to the binder service (root object)
using:
android::String16 service_name("fi.w1.wpa_supplicant");
android::sp<android::IBinder> binder =
  android::defaultServiceManager()->getService(service_name);

Once a reference to the root object is retrieved, the clients can
obtain references to other RPC objects using that root object methods.

ba307f8528 P2P: Add a separate pointer to the P2P Device instance
In many places in the code there was a reference to wpa_s->parent to get
from group interface to p2p_dev interface. These places can break if
P2P_DEVICE interface would need to be used with the primary interface as
the group interface, since the parent of the primary interface points to
itself and not the p2p_dev interface.

Fix this by adding a separate "p2pdev" pointer to wpa_supplicant,
it will be the same as parent pointer in most cases but whenever
the primary interface is used as a group interface, change it to
point to the correct p2p_dev interface.

8dd5c1b4e9 HS 2.0: Add a command to retrieve icon with in-memory storage
This adds a new command based Hotspot 2.0 icon retrieval option.

In short, here is the new command sequence:
1. REQ_HS20_ICON <bssid> <file-name>
2. event: RX-HS20-ICON <bssid> <file-name> <size>
3. GET_HS20_ICON <bssid> <file-name> <offset> <size>
   (if needed, repeat with larger offset values until full icon is
   fetched)
5. DEL_HS20_ICON <bssid> <file-name>

REQ_HS20_ICON is a new command that is analogous to HS20_ICON_REQUEST
with the slight difference that an entry to store the icon in memory is
prepared. The RX-HS20-ICON event has been augmented with BSSID,
file-name and size, and GET_HS20_ICON is used to retrieve a chunk of up
to <size> bytes of icon data at offset <offset>. Each chunk is returned
as a base64 encoded fragment, preceded by "HS20-ICON-DATA", BSSID, and
file-name as well as the starting offset of the data.

If there is no entry prepared for the icon when the ANQP result comes
back, hs20_process_icon_binary_file falls back to legacy behavior.

dfaf11d648 P2P: Require fresh scan results for persistent group re-invocation
The P2P group is not yet operating when going through invitation
exchange for re-invocation. Previously, an old cached scan result could
be used to skip the scan immediately after the invitation exchange.
While this may result in the fastest possible connection, it does have
some issues with cases where the GO takes some time to start up. It
would also be at least theoretically possible for some of the BSS
parameters to be different, so having a fresh scan result from the new
GO instance may be desired in any case.

Add a mechanism to skip scan results that have been last updated before
a specific point in time and as the first user for this mechanism,
require chan results to be more recent than the invitation message
exchange for the P2P Client role in persistent group re-invocation case.

b9da88d6c1 P2PS: Authorize any peer for P2PS method if interface address not known
When P2PS PD with default P2PS method is done, the peer that becomes GO
should authorize the client. However, P2PS specification doesn't require
the client to include its intended interface address in PD
Request/Response. As a result, the P2P Client's interface address may not
be known and any address may need to be authorized.

Previously, client's P2P Device Address was used for authorization,
which is not correct when a dedicated interface is used for P2P Client.
This is not resulting in a connection failure, however it causes a
significant delay (until WPS_PIN_TIME_IGNORE_SEL_REG elapses). Fix this
by authorizing the intended interface address, if known; or any address,
if not known.

without P2P IE are not saved in the BSS table, so non-P2P BSS's with

Fix this by iterating only the WPS AP array instead of the BSS table.
This is also more efficient since only WPS APs may have active PBC. This
also fixes hwsim test "grpform_pbc_overlap" when a dedicated P2P Device

initial three scan results so quickly that the total amount of time is
only couple of seconds in case none of the APs are initially advertising
Selected Registrar TRUE. To give some more time for APs (WPS Registrars)

a1b790eb9d Select AP based on estimated maximum throughput
This modifies the BSS selection routines to calculate SNR and estimated
throughput for each scan result and then use the estimated throughput as
a criteria for sorting the results. This extends the earlier design by
taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is
restricted based on SNR.

In practice, this gives significantly higher probability of selecting
HT/VHT APs when there are multiple BSSes in the same ESS and SNR is not
low enough to prevent higher MCS use.

bf51f4f82b mesh: Fix remaining BLOCKED state after SAE auth failure
When SAE authentication fails, wpa_supplicant retries four times. If all
the retries result in failure, SAE state machine enters BLOCKED state.
Once it enters this state, wpa_supplicant doesn't retry connection. This
commit allow connection retries even if the state machine entered
BLOCKED state.

There could be an opinion "Is this patch needed? User could know the SAE
state machine is in the BLOCKED mode by MESH-SAE-AUTH-BLOCKED event.
Then user can retry connection. By user action, SAE state machine can
change the state from BLOCKED to another.". Yes, this is a true at the
joining mesh STA. However, a STA that is already a member of existing
mesh BSS should not retry connection because if the joining mesh STA
used wrong password, all the existing STA should do something from UI to
retry connection.

In case the AP we are associating with advertises support for RRM,
advertise our own RRM support in the (Re)Association Request frame. This
is done by adding an RRM Capabilities IE. The underlying driver is
expected to further add a Power Capabilities IE to the request, and set
the Radio Measurement flag in the Capability Info field. At this point
the RRM Capabilities IE advertises no measurement support.
