148de3e0dc DPP3: Private Peer Introduction protocol
Add a privacy protecting variant of the peer introduction protocol to
allow the station device to hide its Connector from 3rd parties. The new
wpa_supplicant network profile parameter dpp_connector_privacy=1 can be
used to select this alternative mechanism to the peer introduction
protocol added in the initial release of DPP.

It should be noted that the new variant does not work with older DPP APs
(i.e., requires support for release 3). As such, this new variant is
disabled by default.

bafe35df03 Move CHANWIDTH_* definitions from ieee80211_defs.h to defs.h
Move most of CHANWIDTH_* definitions from ieee80211_defs.h to defs.h as
the definitions are getting used mostly for internal purpose only. Also
change prefix of the definitions to CONF_OPER_CHWIDTH_* and update in
all the files accordingly.

Leave the couple of VHT-specific exceptions to use the old defines (the
reason why they were originally added as VHT values), to avoid use of
clearly marked configuration values in information elements. In
addition, use the defines instead of magic values where appropriate.

62657365f8 Add a configuration to disconnect on deinit if WoWLAN is enabled
Commit 02c21c02d0 ("wpa_supplicant: Do not disconnect on deinit if
WoWLAN is enabled") prevents the disconnection on deinit if the driver
indicates that WoWLAN is enabled. This is not the expected behavior in
some earlier use cases where the wpa_supplicant process is left running
when going to sleep and killing of the wpa_supplicant process is used
only when there is an expectation of Wi-Fi connection being disabled.

To support the use cases which require the WLAN to disconnect on deinit
even if WoWLAN is enabled, introduce a configuration parameter
wowlan_disconnect_on_deinit. This is set to 0 by default thereby not
impacting the functionality in the above mentioned commit. Setting it to
1 restores the old behavior before the commit identified above.

f2a0101401 wpa_supplicant: Initial connection speedup
Add initial_freq_list to wpa_supplicant configuration. This option
allows wpa_supplicant to scan a smaller list of frequencies when it
starts. This in turn allows for a faster connection to an already known
network. This limit applies only for the initial scan operation and does
not restrict other channels from being used in consecutive scans.

Tests have shown this to reduce the amount of time for connecting to a
network from roughly 3 seconds to roughly 0.1 second.

cff545720e wpa_supplicant: Clear blacklist when SSID configs change
If the stored configurations for an SSID have changed, we can no longer
trust the current blacklist state of that SSID, since the updated
configs could change the behavior of the network. E.g., the BSS could be
blacklisted due to a bad password, and the config could be updated to
store the correct password. In this case, keeping the BSS in the
blacklist will prevent the user from connecting to the BSS after the
correct password has been updated.

Add the value was_changed_recently to the wpa_ssid struct. Update this
value every time a config is changed through wpa_set_config(). Check
this value in wpa_blacklist_get() to clear the blacklist whenever the
configs of current_ssid have changed.

This solution was chosen over simply clearing the blacklist whenever
configs change because the user should be able to change configs on an
inactive SSID without affecting the blacklist for the currently active
SSID. This way, the blacklist won't be cleared until the user attempts
to connect to the inactive network again. Furthermore, the blacklist is
stored per-BSSID while configs are stored per-SSID, so we don't have the
option to just clear out certain blacklist entries that would be
affected by the configs.

Finally, the function wpa_supplicant_reload_configuration() causes the
configs to be reloaded from scratch, so after a call to this function
all bets are off as to the relevance of our current blacklist state.
Thus, we clear the entire blacklist within this function.

5058f771d9 DPP2: Allow station to require or not allow PFS
The new wpa_supplicant network profile parameter dpp_pfs can be used to
specify how PFS is applied to associations. The default behavior
(dpp_pfs=0) remains same as it was previously, i.e., try to use PFS if
the AP supports it. PFS use can now be required (dpp_pfs=1) or disabled
(dpp_pfs=2).

This is also working around an interoperability issue of DPP R2 STA with
certain hostapd builds that included both OWE and DPP functionality.
That issue was introduced by commit 09368515d1 ("OWE: Process
Diffie-Hellman Parameter element in AP mode") and removed by commit
16a4e931f0 ("OWE: Allow Diffie-Hellman Parameter element to be
included with DPP"). hostapd builds between those two commits would
reject DPP association attempt with PFS. The new wpa_supplicant default
(dpp_pfs=0) behavior is to automatically try to connect again with PFS
disabled if that happens.

This allows a P2P connection over P802.11ay EDMG channels to achieve the
highest link speed that the standard allows for channel bonding (CB) up
to CB4.

Let each P2P peer add its EDMG channels to the Supported Channels IE

negotiate for operating channel.

User may add 'edmg' parameter to p2p_connect, p2p_add_group, and
p2p_invite commands to prefer an EDMG channel for the P2P link. User may
also set p2p_go_edmg=1 in wpa_supplicant configuration file to prefer
EDMG.

When EDMG is used, P2P will try to find the highest channel bonding
supported channel that matches the frequency parameter, if the devices
do not support EDMG, the P2P connection will use a legacy (1-6) 60 GHz
channel.

a non-zero exit code.
