37bccfcab8 DPP3: Push button bootstrap mechanism
Add support to use a push button -based bootstrap mechanism with DPP.
The new DPP_PUSH_BUTTON control interface command enables this mode on
the AP/hostapd and station/wpa_supplicant. This goes through the
following sequence of events: a suitable peer in active push button mode
is discovered with session overlap detection, PKEX is executed with
bootstrap key hash validation, DPP authentication and configuration
exchanges are performed.

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.

4383528e01 P2P: Use weighted preferred channel list for channel selection
Previously, the driver could optionally (using QCA vendor command)
provide a preferred channel list to wpa_supplicant for channel selection
during the GO negotiation. Channel selection process can be more
efficient with the information of weights and flags of the preferred
channel list that can be provided by the driver. Use a weighted
preferred channel list provided by the driver for channel selection
during GO negotiation if such a list is available.

79dc7f6190 scan: Add option to disable 6 GHz collocated scanning
Add a parameter (non_coloc_6ghz=1) to the manual scan command to disable
6 GHz collocated scanning.

This option can be used to disable 6 GHz collocated scan logic. Note
that due to limitations on Probe Request frame transmissions on the 6
GHz band mandated in IEEE Std 802.11ax-2021 it is very likely that
non-PSC channels would be scanned passively and this can take a
significant amount of time.

033ad6ffaa DPP: Allow Configurator parameters to be provided during config exchange
This provides an alternative mechanism for upper layer components to
control configuration parameters to be used by the local Configurator.
Instead of the previously used design where the Configurator parameters
had to be provided before initiating the DPP Authentication exchange,
the new alternative approach allows the DPP Authentication exchange to
be started before any Configurator parameters have been determined and
wpa_supplicant will then request the parameters once the DPP
Configuration Request has been received from the Enrollee. This allows
the Config Request information to be used at upper layers to determine
how the Enrollee should be configured.

For example for an Initiator:

CTRL: DPP_QR_CODE <URI from Responder/Enrollee>
CTRL: DPP_AUTH_INIT peer=1 conf=query
<3>DPP-CONF-NEEDED peer=1 src=02:00:00:00:00:00 net_role=sta name="Test" opclass=81,82,83,84,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130 mud_url=N/A
(upper layer processing; potentially including user interaction)
CTRL: DPP_CONF_SET peer=1 conf=sta-sae ssid=736165 pass=70617373776f7264
<3>DPP-CONF-SENT

For example for a Responder:

CTRL: SET dpp_configurator_params conf=query
CTRL: DPP_LISTEN 2412 role=configurator
<3>DPP-CONF-NEEDED peer=2 src=02:00:00:00:01:00 net_role=sta name="Test" opclass=81,82,83,84,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130 mud_url=N/A
(upper layer processing; potentially including user interaction)
CTRL: DPP_CONF_SET peer=2 conf=sta-sae ssid=736165 pass=70617373776f7264
<3>DPP-CONF-SENT

For example for an Initiator that can act both as a Configurator and an
Enrollee in a case where the Initiator becomes the Enrollee:

CTRL: DPP_AUTH_INIT peer=1 role=either conf=query
<3>DPP-CONF-RECEIVED

While creating a cloned PMKSA entry for OKC both expiration and

greater than expiration time in some cloned entries. To avoid this copy
reauth_time also to the cloned entry.

Also, add check to reject control interface commands with reauth time

ce267f4da9 P2P: DFS offload for the autonomous GO
Enhance the P2P_GROUP_ADD command to support DFS channel with 80 and 160
MHz bandwidth to be used for autonomous GO when using offloaded DFS.

For example, 'P2P_GROUP_ADD freq=5500 max_oper_chwidth=80 ht40 vht'

- Previous behavior: AP fallback to channel 100 using 20 MHz with
  "No VHT higher bandwidth support for the selected channel 100"
- Enhanced behavior: AP starts on channel 100 using 80 MHz with
  "VHT center channel 106 for 80 or 80+80 MHz bandwidth"

This functionality is on top of the driver's capability to offload DFS,
which is advertized through WPA_DRIVER_FLAGS_DFS_OFFLOAD.

5ac977758d Reject authentication start during explicit roam requests
The roam D-Bus and ROAM control itnerface commands flip the reassociate
bit before calling wpa_supplicant_connect(). wpa_supplicant connect
eventually aborts ongoing scans (if any), which causes scan results to
be reported. Since the reassociate bit is set, this will trigger a
connection attempt based on the aborted scan's scan results and cancel
the initial connetion request. This often causes wpa_supplicant to
reassociate to the same AP it is currently associated to instead of the
explicitly requested roaming target.

Add a roam_in_progress flag to indicate that we're currently attempting
to roam via an explicitly request to a specific BSS so that we don't
initiate another connection attempt based on the possibly received scan
results from a scan that was in progress at the time the roam command
was received.

c2c4686228 Set NLA_F_NESTED flag with NL80211_ATTR_VENDOR_DATA conditionally
The newer kernel versions enforce strict netlink attribute policy
validation and will cause cfg80211 to reject vendor commands with
NL80211_ATTR_VENDOR_DATA if NLA_F_NESTED attribute is not set but
if the vendor command is expecting nested data within
NL80211_ATTR_VENDOR_DATA attribute.

Most of the earlier instances were addressed by adding NLA_F_NESTED
flag in nla_nest_start(). This commit addresses the remaining
instance in which NL80211_ATTR_VENDOR_DATA is populated using data
set by user through the control interface.

Enhance the control interface VENDOR command to indicate whether the
vendor subcommand uses nested attributes within NL80211_ATTR_VENDOR_DATA
attribute or not.

Set NLA_F_NESTED flag for existing QCA vendor commands which use nested
attributes within the NL80211_ATTR_VENDOR_DATA attributes so that the
old frameworks implementations for already existing commands work
without any issues.

2fd35d9857 wpa_supplicant: Track consecutive connection failures
Within wpas_connection_failed(), the 'count' value of wpa_blacklist is
erroneously used as a tally of the number times the device has failed
to associate to a given BSSID without making a successful connection.
This is not accurate because there are a variety of ways a BSS can be
added to the blacklist beyond failed association such as interference
or deauthentication. This 'count' is lost whenever the blacklist is
cleared, so the wpa_supplicant stores an additional value
'extra_blacklist_count' which helps persist the 'count' through clears.
These count values are used to determine how long to wait to rescan
after a failed connection attempt.

While this logic was already slightly wrong, it would have been
completely broken by the upcoming change which adds time-based
blacklisting functionality. With the upcoming change, 'count' values
are not cleared on association, and thus do not necessarily even
approximate the "consecutive connection failures" which they were being
used for.

This change seeks to remove this unnecessary overloading of the
blacklist 'count' by directly tracking consecutive connection failures
within the wpa_supplicant struct, independent of the blacklist. This new
'consecutive_conn_failures' is iterated with every connection failure
and cleared when any successful connection is made. This change also
removes the now unused 'extra_blacklist_count' value.

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.

a919a26035 Introduce and add key_flag
Add the new set_key() parameter "key_flag" to provide more specific
description of what type of a key is being configured. This is needed to
be able to add support for "Extended Key ID for Individually Addressed
Frames" from IEEE Std 802.11-2016. In addition, this may be used to
replace the set_tx boolean eventually once all the driver wrappers have
moved to using the new key_flag.

The following flag are defined:

  KEY_FLAG_MODIFY
    Set when an already installed key must be updated.
    So far the only use-case is changing RX/TX status of installed
    keys. Must not be set when deleting a key.

  KEY_FLAG_DEFAULT
    Set when the key is also a default key. Must not be set when
    deleting a key. (This is the replacement for set_tx.)

  KEY_FLAG_RX
    The key is valid for RX. Must not be set when deleting a key.

  KEY_FLAG_TX
    The key is valid for TX. Must not be set when deleting a key.

  KEY_FLAG_GROUP
    The key is a broadcast or group key.

  KEY_FLAG_PAIRWISE
    The key is a pairwise key.

  KEY_FLAG_PMK
    The key is a Pairwise Master Key (PMK).

Predefined and needed flag combinations so far are:

  KEY_FLAG_GROUP_RX_TX
    WEP key not used as default key (yet).

  KEY_FLAG_GROUP_RX_TX_DEFAULT
    Default WEP or WPA-NONE key.

  KEY_FLAG_GROUP_RX
    GTK key valid for RX only.

  KEY_FLAG_GROUP_TX_DEFAULT
    GTK key valid for TX only, immediately taking over TX.

  KEY_FLAG_PAIRWISE_RX_TX
    Pairwise key immediately becoming the active pairwise key.

  KEY_FLAG_PAIRWISE_RX
    Pairwise key not yet valid for TX. (Only usable with Extended Key ID
    support.)

  KEY_FLAG_PAIRWISE_RX_TX_MODIFY
    Enable TX for a pairwise key installed with KEY_FLAG_PAIRWISE_RX.

  KEY_FLAG_RX_TX
    Not a valid standalone key type and can only used in combination
    with other flags to mark a key for RX/TX.

This commit is not changing any functionality. It just adds the new
key_flag to all hostapd/wpa_supplicant set_key() functions without using
it, yet.
