The GAS client processing of the response callback for DPP did not
properly check for GAS query success. This could result in trying to
check the Advertisement Protocol information in failure cases where that
information is not available and that would have resulted in
dereferencing a NULL pointer. Fix this by checking the GAS query result
before processing with processing of the response.
This is similar to the earlier wpa_supplicant fix in commit 931f7ff656
("DPP: Fix GAS client error case handling").

When ERP initialization was moved from the METHOD state to the SUCCESS

Reordering of code in handle_auth_cb() when adding support for full

state changes was after having read six octets of the payload which did
not help at all since there was no addition accesses to the payload
after that check.
Move the payload length check to appropriate place to get this extra

The main OpenSSL wrapper change in tls_connection_decrypt() takes care
of the new possible case with SSL_MODE_AUTO_RETRY for
SSL_ERROR_WANT_READ to indicate that a non-application_data was

It was not easily possible to separate configuration of an interface and
credentials when using the configuration file instead of the control
interface or D-Bus interface for setting up the network profiles. This
makes it hard to distribute configuration across a set of nodes which
use wpa_supplicant without also having to store credentials in the same
file. While this can be solved via scripting, having a native way to
achieve this would be preferable.
Turns out there already is a framework to have external password
storages. It only had a single "test" backend though, which is kind of
an in-memory store which gets initialized with all passwords up front
and is mainly for testing purposes. This isn't really suitable for the
above use case: the backend cannot be initialized as part of the central
configuration given that it needs the credentials, and we want to avoid
scripting.
This commit thus extends the infrastructure to implement a new backend,
which instead uses a simple configuration file containing key-value
pairs. The file follows the format which wpa_supplicant.conf(5) uses:
empty lines and comments are ignored, while passwords can be specified
with simple `password-name=password-value` assignments.
With this new backend, splitting up credentials and configuration
becomes trivial:
# /etc/wpa_supplicant/wpa_supplicant.conf
ext_password_backend=file:/etc/wpa_supplicant/psk.conf
network={
ssid="foobar"
psk=ext:foobar
}
# /etc/wpa_supplicant/psk.conf
foobar=ecdabff9c80632ec6fcffc4a8875e95d45cf93376d3b99da6881298853dc686b
Alternative approaches would be to support including other configuration
files in the main configuration, such that common configuration and
network declarations including credentials are split up into separate
files. But the implementation would probably have been more complex
compared to reusing the already-existing framework for external password
backends.

This was broken because allowed_ht40_channel_pair() returns true in this

failure to bring interface up.

When wpa_supplicant sends NL80211_CMD_AUTHENTICATE to kernel, it is
possible that the cfg80211 in kernel has expired the BSS entry that
we are trying to auth with. Then cfg80211 will reject the auth cmd.
In this case, wpa_supplicant will trigger a single channel scan to
refresh cfg80211 BSS entry, and retry the auth when scan is finished.
When this case happens, wpa_supplicant makes a copy of auth params,
such as frequency, bssid, ssid, ie and so on. So when we retry auth,
the copy of these params will be used. The problem is, a param named
auth_data is missed when making the copy. The auth_data is used by

NL80211_CMD_ROAM indication is scheduled via a kernel work queue, while

After a disconnect command is issued, wpa_supplicant generates a
disconnection event to self and ignores the next disconnection event
coming from the driver. In a race condition in which the driver
generates a connected event due to roaming just before receiving the
disconnect command from userspace, wpa_supplicant processes the
connected event after processing the self-generated disconnection event
and enters WPA_COMPLETED state. The driver sends a disconnection event
after processing the disconnect command sent by wpa_supplicant but the
disconnection event is ignored by wpa_supplicant as the disconnection
event is considered to be a result of locally generated disconnect
command. Thus, wpa_supplicant continues to be in the connected
(WPA_COMPLETED) state though the driver is in disconnected state.
Fix this out-of-sync behavior between the driver and wpa_supplicant by
not ignoring the disconnection event from the driver because of the
locally generated disconnect command sent to the driver if there is a
connection event received after issuing the disconnect command to the
driver.

The earlier workaround for UBSAN issues in commit 3b6b3ae581 ("Modify

using a construction in which the type cast to the containing structure
was compared instead of the struct dl_list pointers. While that worked
around the UBSAN issue, it resulted in a comparison that gcc-10
interprets as being out of bounds for struct dl_list (which it obviously
is since this is to find the start of the containing structure).
Revert that workaround and instead, mark the struct dl_list used within
struct os_alloc_trace to have matching 16 octet alignment as the

Some legacy stations copy previously reserved RSN capability bits,
including OCVC, in (Re)Association Request frames from the AP's RSNE but
do not indicate MFP capability and/or do not send OCI in RSN handshakes.
This is causing connection failures with such erroneous STAs.
To improve interoperability with such legacy STAs allow a workaround OCV
mode to be enabled to ignore OCVC=1 from the STA if it does not follow
OCV requirements in the first protected exchange. This covers cases
where a STA claims to have OCV capability, but it does not negotiate use
of management frame protection or does not include OCI in EAPOL Key msg
2/4, FT Reassociation Request frame, or FILS (Re)Association Reqest.
The previous behavior with ocv=1 is maintained, i.e., misbehaving STAs
are not allowed to connect. When the new workaround mode is enabled with
ocv=2, the AP considers STA as OCV capable on below criteria
- STA indicates both OCV and MFP capability
- STA sends OCI during connection attempt in a protected frame
Enabling this workaround mode reduced OCV protection to some extend
since it allows misbehavior to go through. As such, this should be
enabled only if interoperability with misbehaving STAs is needed.

When a Presence Announcement frame is received, a check is done to
ensure an ongoing auth is not in progress (!hapd->dpp_auth). A new DPP
auth is then initialized, however, when setting global configurator
params for it, the hapd->dpp_auth pointer is used which was earlier
confirmed as NULL, causing a crash in dpp_set_configurator params when
the pointer is dereferenced.
This only occurs when there are global DPP configurator params to be set
and the peer has no overriding configurator params. If no global DPP
configurator params exist, the call to dpp_set_configurator exits early
and the problem is not observed.

If reassoc_same_bss_optim=1 is used to optimize reassociation back to
the same BSS, it was possible for sm->pmk_len to be 0 due to a
disconnection event getting processed after sending out the
reassociation request. This resulted in wpa_sm_rx_eapol() calling
wpa_mic_len() with incorrect PMK length when PMKSA caching was being
attempted. That resulted in incorrect mic_len getting determined and not
finding the correct Key Data Length field value. This could result in
failing to complete 4-way handshake successfully.
Fix this by updating the current PMK length based on the selected PMKSA
cache entry if sm->pmk_len is not set when processing EAPOL-Key msg 1/4.

As per RFC 8110 (Opportunistic Wireless Encryption), if the AP has the
PMK identified by the PMKID and wishes to perform PMK caching, it will
include the PMKID in the Association Response frame RSNE but does not
include the Diffie-Hellman Parameter element.
This was already addressed for most cases with owe_process_assoc_req()
not setting sta->owe_ecdh in case PMKSA caching is used. However, it was
possible to an old STA entry to maintain the initial sta->owe_ecdh value
if reassociation back to the same AP was used to initiate the PMKSA
caching attempt. Cover that case by adding an explicit check for the
time when the Association Response frame is being generated.

Corrects the documentation for QCA_WLAN_TWT_SUSPEND and

parameters obtained through QCA_WLAN_VENDOR_ATTR_CONFIG_TWT_PARAMS. This
interface is very recently introduced and missed to document the same.
There are no user space or driver components using this interface yet.
Hence, enhancing/modifying the interface.
Corrects the documentation for
QCA_WLAN_VENDOR_ATTR_TWT_SETUP_WAKE_DURATION. Mentions that the units it
represent is a multiple of 256 microseconds rather than a TU. The host
driver always interpreted this as an unit in 256 microseconds and there
are no user space implementations that are impacted with this change in
the unit. Hence, modifying the documentation.
Introduces QCA_WLAN_VENDOR_ATTR_TWT_RESUME_NEXT2_TWT_SIZE, which is
similar to that of QCA_WLAN_VENDOR_ATTR_TWT_RESUME_NEXT_TWT, but carries
an offset/data of u32 size.

When a single hostapd process manages both the OWE and open BSS for
transition mode, owe_transition_ifname can be used to clone the
transition mode information (i.e., BSSID/SSID) automatically. When both
BSSs use ACS, the completion of ACS on the 1st BSS sets state to
HAPD_IFACE_ENABLED and the OWE transition mode information is updated
for all the other BSSs. However, the 2nd BSS is still in the ACS phase
and the beacon update messes up the state for AP startup and prevents
proper ACS competion.
If 2nd BSS is not yet enabled (e.g., in ACS), skip beacon update and
defer OWE transition information cloning until the BSS is enabled.

It is possible for drivers to report received Management frames while AP
is going through initial setup (e.g., during ACS or DFS CAC). hostapd
and the driver is not yet ready for actually sending out responses to
such frames at this point and as such, it is better to explicitly ignore
such received frames rather than try to process them and have the
response (e.g., a Probe Response frame) getting dropped by the driver as
an invalid or getting out with some incorrect information.

This allows nl80211-based drivers to get the frame out. The old earlier
location resulted in the driver operation getting rejected before the
kernel was not ready to transmit the frame in the BSS context of the AP
interface that has not yet been started.
While getting this broadcast Deauthentication frame transmitted at the
BSS start is not critical, it is one more chance of getting any
previously associated station notified of their previous association not
being valid anymore had they missed previous notifications in cases
where the AP is stopped and restarted.

Documentation of the return values for wpa_parse_vendor_specific() and
wpa_parse_generic() were not accurate and the parsing results from these
were not really handled appropriately. There is no point in calling
wpa_parse_vendor_specific() if wpa_parse_generic() recognizes a KDE. Not
that this would break anything in practice, but still, it looks
confusing.
The part about handling wpa_parse_vendor_specific() return value can, at
least in theory, break some cases where an unexpectedly short KDE/vendor
specific element were present and something would need to be recognized
after it. That does not really happen with any standard compliant
implementation and this is unlikely to cause any real harm, but it is
clearer to handle this more appropriately even for any theoretical case,
including misbehavior of a peer device.
Instead of stopping parsing on too short vendor specific element,
continue parsing the following KDEs/IEs. Skip the
wpa_parse_vendor_specific() call when a KDE has been recognized. Also
fix the return value documentation for wpa_parse_generic() and remove
the useless return value from wpa_parse_vendor_specific().
