90f14962ec wpa_supplicant: "don't care" value for pbss in ssid structure
Add a new value 2 to the pbss parameter of wpa_ssid structure, which
means "don't care". This value is used in infrastructure mode to request
connection to either AP or PCP, whichever is available in the scan
results. The value is also used in regular WPS (not P2P group formation)
to make WPS work with devices running as either AP or PCP.

3560b32ca3 Fix race condition with PNO stop followed immediately by PNO start
Commit dd271857a5 ('Skip normal scan when
PNO is already in progress') fixed issues with normal scans getting
rejected by the driver when PNO scan is already running. The part about
skipping such a scan request is fine, but the part about clearing
wpa_s->pno back to 0 in EVENT_SCHED_SCAN_STOPPED handler is problematic.

If PNO is stopped ("SET pno 0") and then restarted ("SET pno 1")
immediately, it is possible for the EVENT_SCHED_SCAN_STOPPED event from
the stopping part to be received only after the new PNO instance has
been started. This would have resulted in clearing wpa_s->pno and the
driver and wpa_supplicant getting out of sync. This would then prevent
PNO from being stopped with "SET pno 0" (that fails if wpa_s->pno == 0).

Fix this race condition by reverting the wpa_s->pno = 0 addition from
the EVENT_SCHED_SCAN_STOPPED handler.

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.

This struct in the union is empty, but the design of using a zero-length

undesired compiler warnings. Since there are no non-IE fields in the

5cd317d381 Do not clear PMKSA entry or EAP session cache if config does not change
This avoids unnecessary flushing of the PMKSA cache entry and EAP
session data when processing SET_NETWORK commands that set a network
profile parameter to the same value that the parameter already has.

Introduce a new wpa_config_set() and wpa_config_set_quoted() return
value (==1) signifying that the new value being set for the
corresponding field equals to the already configured one so that the
caller can determine that nothing changed in the profile.

For now, this does not cover all the network profile parameters, but
number of the most commonly used parameters are included to cover the
Android use cases where the framework may have issued SET_NETWORK
commands that would have unnecessarily prevented use of PMKSA caching or
EAP fast reauthentication.

954e10e483 Make it a bit easier to roam from 2.4 GHz to 5 GHz within ESS
The initial connection to an ESS was already explicitly increasing the
likelihood of picking a 5 GHz BSS. While the throughput estimation is
likely to do same for the roaming decision, it might be possible that
that does not cover all cases. Add couple of dB extra preference for 5
GHz in case the roaming decision falls back to comparing signal levels.

90377029c6 wpa_supplicant: Fix CONFIG_IBSS_RSN=y build without CONFIG_AP=y
Commit 1889af2e0f ('VLAN: Separate station
grouping and uplink configuration') added an ap_sta_set_vlan() function
that gets called from pmksa_cache_auth.c. This broke CONFIG_IBSS_RSN=y
build if src/ap/sta_info.c did not get included in the build, i.e., if
CONFIG_AP=y was not set.

Fix this by making the ap_sta_set_vlan() call conditional on
CONFIG_NO_VLAN being undefined and define this for CONFIG_IBSS_RSN=y
builds. This is fine for wpa_supplicant since CONFIG_AP=y case was
already defining this. For hostapd, this function call is not needed for
CONFIG_NO_VLAN case either.

d774c46aae mesh: Use appropriate BLOCKED state duration
Previously, BLOCKED state duration slightly increased up to 3600. Though
the BLOCKED state could be canceled by ap_handle_timer(). Because the
timer timeouts in ap_max_inactivity(default=300sec) and remove STA
objects (the object retains BLOCKED state).

This patch re-designs my commit bf51f4f82b

mesh_auth_block_duration by ap_max_inactivity and remove incremental

9f2cf23e2e mesh: Add support for PMKSA caching
This patch add functionality of mesh SAE PMKSA caching. If the local STA
already has peer's PMKSA entry in the cache, skip SAE authentication and
start AMPE with the cached value.

If the peer does not support PMKSA caching or does not have the local
STA's PMKSA entry in the cache, AMPE will fail and the PMKSA cache entry
of the peer will be removed. Then STA retries with ordinary SAE
authentication.

If the peer does not support PMKSA caching and the local STA uses
no_auto_peer=1, the local STA can not retry SAE authentication because
NEW_PEER_CANDIDATE event cannot start SAE authentication when
no_auto_peer=1. So this patch extends MESH_PEER_ADD command to use
duration(sec). Throughout the duration, the local STA can start SAE
authentication triggered by NEW_PEER_CANDIDATE even though
no_auto_peer=1.

This commit requires commit 70c93963ed
('SAE: Fix PMKID calculation for PMKSA cache'). Without that commit,
chosen PMK comparison will fail.
