0cb39f4fd5 HE: Extend BSS color support
The HE Operation field for BSS color consists of a disabled, a partial,
and 6 color bits. The original commit adding support for BSS color
considered this to be a u8. This commit changes this to the actual
bits/values.

This adds an explicit config parameter for the partial bit. The disabled
is set to 0 implicitly if a bss_color is defined.

Interoperability testing showed that stations will require a BSS color
to be set even if the feature is disabled. Hence the default color is 1
when none is defined inside the config file.

2bab073dfe WPS: Add new PSK entries with wps=1 tag
Now that hostapd wpa_psk_file has a new tag for identifying PSKs that
can be used with WPS, add that tag to new entries for PSKs from WPS.
This makes it clearer where the PSK came from and in addition, this
allows the same PSK to be assigned if the same Enrollee goes through WPS
provisioning again.

fde8e79463 WPS: Make it possible to use PSKs loaded from the PSK file
By default, when configuration file set wpa_psk_file, hostapd generated
a random PSK for each Enrollee provisioned using WPS and appended that
PSK to wpa_psk_file.

Changes that behavior by adding a new step. WPS will first try to use a
PSK from wpa_psk_file. It will only try PSKs with wps=1 tag.
Additionally it'll try to match enrollee's MAC address (if provided). If
it fails to find an appropriate PSK, it falls back to generating a new
PSK.

8f8473cebb SAE: Fix peer-commit-scalar reuse check
Only one peer-commit-scalar value was stored for a specific STA (i.e.,
one per MAC address) and that value got replaced when the next SAE
Authentication exchange was started. This ended up breaking the check
against re-use of peer-commit-scalar from an Accepted instance when
anti-clogging token was requested. The first SAE commit message (the one
without anti-clogging token) ended up overwriting the cached
peer-commit-scalar value while leaving that instance in Accepted state.
The second SAE commit message (with anti-clogging token) added ended up
getting rejected if it used the same value again (and re-use is expected
in this particular case where the value was not used in Accepted
instance).

Fix this by using a separate pointer for storing the peer-commit-scalar
value that was used in an Accepted instance. There is no need to
allocate memory for two values, i.e., it is sufficient to maintain
separate pointers to the value and move the stored value to the special
Accepted state pointer when moving to the Accepted state.

This fixes issues where a peer STA ends up running back-to-back SAE
authentication within couple of seconds, i.e., without hostapd timing
out the STA entry for a case where anti-clogging token is required.

65a44e849a OWE: PTK derivation workaround in AP mode
Initial OWE implementation used SHA256 when deriving the PTK for all OWE
groups. This was supposed to change to SHA384 for group 20 and SHA512
for group 21. The new owe_ptk_workaround parameter can be used to enable
workaround for interoperability with stations that use SHA256 with
groups 20 and 21. By default, only the appropriate hash function is
accepted. When workaround is enabled (owe_ptk_workaround=1), the
appropriate hash function is tried first and if that fails, SHA256-based
PTK derivation is attempted. This workaround can result in reduced
security for groups 20 and 21, but is required for interoperability with
older implementations. There is no impact to group 19 behavior.

4bf78a79d0 ACS: Populate channel config from external ACS per documented behavior
Based on the now documented seg0/seg1 values from offloaded ACS, there
is a mismatch between the driver interface and internal hostapd use.

The value of segment0 field in ACS results is the index of the channel
center frequency for 20 MHz, 40 MHz, and 80M Hz channels. The value is
the center frequency index of the primary 80 MHz segment for 160 MHz and
80+80 MHz channels.

The value of segment1 field in ACS results is zero for 20 MHz, 40 MHz,
and 80 MHz channels. The value is the index of the channel center
frequency for 160 MHz channels and the center frequency index of the
secondary 80 MHz segment for 80+80 MHz channels.

However, in struct hostapd_config, for 160 MHz channels, the value of
the segment0 field is the index of the channel center frequency of 160
MHz channel and the value of the segment1 field is zero. Map the values
from ACS event into hostapd_config fields accordingly.

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.

4834c6869d FT: Fix hostapd_wpa_auth_oui_iter() iteration for multicast packets
When using FT wildcard feature, the inter-AP protocol will send
broadcast messages to discover related APs.

For example,
12/6 16:24:43 FT: Send PMK-R1 pull request to remote R0KH address
    ff:ff:ff:ff:ff:ff
12/6 16:24:43 FT: Send out sequence number request to
    ff:ff:ff:ff:ff:ff

If you have multiple interfaces/BSSs in a single hostapd process,
hostapd_wpa_auth_oui_iter() returned 1 after the first interface was
processed. Iteration in for_each_interface() will be stopped since it
gets a non-zero return value from hostapd_wpa_auth_oui_iter().

Even worse, the packet will not be sent to ethernet because
for_each_interface() returns non-zero value. hostapd_wpa_auth_send_oui()
will then return data_len immediately.

To prevent this, hostapd_wpa_auth_oui_iter() should not return 1 after
any successful transmission to other interfaces, if the dst_addr of
packet is a multicast address.

ef48f1bfb3 Ensure authenticator session timer is applied with wired driver
We use the wired driver for wired port authentication with a slight
extension to add the port into a bridge upon successful authentication
and to remove it from the bridge when the session terminates.

Our expectation was that the Session-Timeout configuration at the RADIUS
server is respected, i.e. the session is terminated and would need
re-authentication - like it is working for WLAN sessions over the
nl80211 driver. Alas, it turned out the session is not terminated with
the wired driver.

It turned out that when ap_handle_session_timer() is executed, the
sta->flags of the wired port has only the WLAN_STA_AUTHORIZED bit set.
The WLAN_STA_AUTH bit, which is used to check whether the STA needs to
be de-authenticated, is missing.

Extend the check for any of the WLAN_STA_(AUTH | ASSOC | AUTHORIZED)
bits to solve this issue with the wired driver. That should not have any
side-effect for the WLAN cases since WLAN_STA_AUTH is expected to always
be set for those when there is an ongoing session and separate checks
for ASSOC and AUTHORIZED don't change this.

EAPOL-Key message 1/4 without PMKID KDE was sent with 22 bytes of stray

e780b4bf20 DPP: Bootstrapping via NFC URI Record
This extends hostapd and wpa_supplicant DPP implementation to allow the
bootstrapping URI to be generated for and parsed from an NFC Tag with an
NFC URI Record. This is similar to the way the bootstrapping URI is used
with QR Code for unidirectional authentication.

The DPP_BOOTSTRAP_GEN command uses "type=nfc-uri" to request the URI to
be assigned for NFC URI Record. In practice, the URI is generated
identically to the QR Code case, but the internal entry maintains the
NFC-URI type.

A new command "DPP_NFC_URI <uri>" can now be used to parse the URI read
from an NFC Tag with the NFC URI Record. This is similar to the
DPP_QR_CODE command.

Other commands (mainly, DPP_LISTEN and DPP_AUTH_INIT) are used for NFC
URI in the same way as they are used for QR Code.

5b50265e13 WMM: Do not modify input TSPEC buffer during processing
The WMM TSPEC processor used the input buffer for processing the request
and building the response. This was fine for the FT case, but for the
WMM Action frame case, the input buffer is marked const, so it should
not really be modified. This modification could not really cause any
noticeable harm, but it can result in error reports from fuzzing and
potentially even from some static analyzers.

Fix this by marking the input arguments const more consistently (the
parsed IE was able to drop the const) and copy the const input data to a
temporary buffer for processing and modification instead of allowing the
input data to be modified.

wpa_validate_wpa_ie() was already extended to cover these cases with
WPA_INVALID_PMKID return value, but hostapd_notif_assoc() did not have
code for mapping this into the appropriate status code

(WLAN_STATUS_INVALID_IE) instead. This caused AP SME-in-driver cases
returning incorrect status code when the AP did not have a matching
PMKSA cache entry. This could result in unexpected station behavior
where the station could continue trying to use a PMKSA cache entry that
the AP does not have and not being able to recover this.

Fix this by adding the previously missed mapping of validation errors to
status/reason codes.

93a1e275a7 SAE: Determine H2E vs. looping when restarting SAE auth in AP mode
If hostapd had existing STA SAE state, e.g., from a previously completed
SAE authentication, a new start of a separate SAE authentication (i.e.,
receiving of a new SAE commit) ended up using some of the previous
state. This is problematic for determining whether to H2E vs. looping
since the STA is allowed (even if not really expected to) to change
between these two alternatives. This could result in trying to use H2E
when STA was using looping to derive PWE and that would result in SAE
confirm failing.

Fix this by determining whether to use H2E or looping for the restarted
authentication based on the Status Code in the new SAE commit message
instead of previously cached state information.
