9359cc8483 P2P: Support random device address
To enhance privacy, generate a random device address for P2P interface.
If there is no saved persistent group, it generate a new random MAC
address on bringing up p2p0. If there is saved persistent group, it will
use last MAC address to avoid breaking group reinvoke behavior.

There are two configurations are introduced:
* p2p_device_random_mac_addr
  enable device random MAC address feature, default disable.
* p2p_device_persistent_mac_addr
  store last used random MAC address.

During P2PS PD Request processing wpa_supplicant removes stale

This can result in leaving behind objects pointing to freed memory and

dc9b7d217c P2P: Set global->p2p_group_formation in wpas_p2p_join_start() for p2pdev
When a dedicated P2P device interface is used, the
global->p2p_group_formation was not set in wpas_p2p_join_start() if no
separate group interface is used. This would cause that in case of a
failure in group formation, the cleaning of p2p_in_provisioning is done
on the wrong interface. Furthermore, P2P_CANCEL command could not be
used to stop such a group-join operation. Fix this by setting the
global->p2p_group_formation correctly in case that the group interface
is reusing wpa_s->parent.

26eac0a998 P2P: Improve common group channel selection if GO needs to be moved
Prefer channels that support VHT80 (and secondarily, HT40 on the same
band) over other common group channels. If no such channel is found,
prefer any channel that uses the same band so that CSA can be used. This
improves the case where a P2P GO needs to move to another channel and
there is no other reason (e.g., preferred channel from the driver or an
already used channel from a virtual interface sharing the same radio) to
pick a specific channel.

Mark a channel as required DFS based on regulatory information received
from the driver/kernel rather than deciding based on hardcoded

37ed3254de P2P: ACS offload for the autonomous GO
This commit introduces the ACS functionality for the autonomous GO. The
optional parameter <freq> in p2p_group_add is enhanced to carry a value
"acs" with the intention to select the channels among any supported
band. freq = 2 / 5 carry the need to select the channels only in the
respective bands 2.4 / 5 GHz. This functionality is on top of the host
driver's capability to offload ACS, which is advertized through
WPA_DRIVER_FLAGS_ACS_OFFLOAD.

f516090228 P2P: Prefer 5/60 GHz band over 2.4 GHz during GO configuration
Previously, wpas_p2p_select_go_freq_no_pref() ended up selecting a 2.4
GHz band channel first before even considering 5 or 60 GHz channels.
This was likely done more or less by accident rather than by design when
the 5 GHz and 60 GHz band extensions were added. It seems reasonable to
enhance this by reordering the code to start with 5 and 60 GHz operating
classes and move to 2.4 GHz band only if no channel was available in 5
or 60 GHz bands for P2P GO use.

This does have some potential interop issues with 2.4 GHz only peer
devices when starting up an autonomous GO (i.e., without there being
prior knowledge of channels that the peers support). Upper layers are
expected to enforce 2.4 GHz selection if that is needed for some use
cases.

supports DFS offload, the frequency was rejected in
wpas_p2p_init_go_params(). However, it was accepted in
wpas_p2p_select_go_freq() and wpas_p2p_group_add(). To make the behavior

618aa22900 P2P: Fix p2p_in_provisioning clearing in failure case
wpa_s->p2p_in_provisioning needs to be cleared when group formation
fully completes. The change to postpone GO side handling to the first
data connection in commit 41f853235f
('P2P: Extend group formation timeout on GO to first data connection')
resulted in making this not happen in one P2P Client side case: EAP-WSC
timeout in PBC case. While that is quite special case since it requires
30 second timeout without receiving new EAPOL frames and not getting
disassociation, it can apparently happen in some cases in practice. This
would result in new P2P operations (e.g., P2P_FIND) getting rejected
until wpa_supplicant is restarted.

Fix this by clearing wpa_s->p2p_in_provisioning whenever processing a
group formation failure case. For group formation success,
wpa_s->p2p_in_provisioning is left set to non-zero value to avoid
breaking the earlier limits on the GO side.

3c2bd55f03 P2P: wpas_p2p_select_go_freq() to check for supported pref_freq
This commit is similar to the commit
783c2920cc ('P2P: Check if the pref_freq
reported by the driver supports P2P') but extends the check for
supported pref_freq to wpas_p2p_select_go_freq().

This avoids issues with P2P_GROUP_ADD ending up selecting an unexpected
channel when get_pref_freq_list() (i.e.,
QCA_NL80211_VENDOR_SUBCMD_GET_PREFERRED_FREQ_LIST) is used. Filter the
list by removing channels that do not allow P2P operation at all.
Previously, only the explicitly disallowed channels were removed and
that could have resulted in selecting an operating channel that is not
allowed for P2P and failing to complete the operation to start the
group.

f49c852b5e P2P: Fix a theoretical out of bounds read in wpas_p2p_select_go_freq()
Commit 8e84921efe ('P2P: Support driver
preferred freq list for Autonomous GO case') introduced this loop to go
through preferred channel list from the driver. The loop does bounds
checking of the index only after having read a value from the array.
That could in theory read one entry beyond the end of the stack buffer.

Fix this by moving the index variable check to be done before using it
to fetch a value from the array.

This code is used only if wpa_supplicant is build with
CONFIG_DRIVER_NL80211_QCA=y and if the driver supports the vendor
extension (get_pref_freq_list() driver op). In addition, the driver
would need to return more than P2P_MAX_PREF_CHANNELS (= 100) preferred
channels for this to actually be able to read beyond the buffer. No
driver is known to return that many preferred channels, so this does not
seem to be reachable in practice.

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.

When starting ASP provisioning with connection capability set to NEW,
don't create the pending P2P interface as a GO interface because
Go negotiation will determine which side will be the GO and it is
possible that eventually this interface will become the client.
In this case, when the P2P client is started it will start scanning
and do other station specific operations while the interface type
is AP.

Instead, use type WPA_IF_P2P_GROUP when creating the interface which
means the interface type will be determined later.

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.

7d46f586de MBO: Add global operating class definitions
Add definitions for global operating classes. These definitions will be
used to construct supported operating classes information element.

The operating classes definitions used locally for P2P module will be
removed and included in the general operating classes definitions.

98a516eae8 WPS: Use only os_get_random() for PIN generation
Remove the fallback dependency on os_random() when generating a WPS pin.
This is exceptionally unlikely to ever be called as the call to
os_get_random() is unlikely to fail. The intention is to facilitate
future removal of os_random() as it uses a low quality PRNG.

b907491281 wpa_supplicant: Basic support for PBSS/PCP
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 IEEE 802.11ad devices.

Add a new "pbss" argument to network block. The argument is used
in the following scenarios:
1. When network has mode=2 (AP), when pbss flag is set will start
as a PCP instead of an AP.
2. When network has mode=0 (station), when pbss flag is set will
connect to PCP instead of AP.

The function wpa_scan_res_match() was modified to match BSS according to
the pbss flag in the network block (wpa_ssid structure). When pbss flag
is set it will match only PCPs, and when it is clear it will match only
APs.

944f693591 P2P: Stop offchannel TX wait on P2P_STOP_FIND/P2P_LISTEN
Previously it was possible for the pending Action frame TX to be
cleared, but the offchannel TX operation being left in wait state in the
kernel. This would delay start of the next operation (e.g., that listen
operation requested by P2P_LISTEN) until the wait time for the
previously pending Action frame had expired.

Optimize this by explicitly stopping any pending offchannel Action frame
TX when clearing the internal offchannel TX state in
wpas_p2p_clear_pending_action_tx().
