Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.
On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.
Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.
As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

If the RADIUS authentication server dropped the cached ERP keys for any
reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for

Address this by trying to use full (non-FILS) authentication when trying

new ERP keys to be established and FILS authentication to be used again

It is possible for scan result processing or BSS entry removal to occur

to be valid, i.e., still point to a BSS entry, at the time the actual

or reallocated and a new BSS entry was added at the same location in
memory. This could result in the connection attempt failing to configure
parameters properly due to different BSS information (e.g., different
BSSID).
Fix this by updated the pending connect radio work data on BSS entry

Previously, the frequency conflict was handled only during the
association flow. However, some drivers, e.g., mac80211 based
drivers, will fail an authentication request in case that there
are no available channels for use (as they might be used by
other interfaces), and thus the frequency conflict resolution
is never called.
Fix this by calling frequency conflict resolution during
authentication (SME-in-wpa_supplicant) as well.
In addition, get the shared radio frequency from the wpa_s context in
both the SME-in-driver and SME-in-wpa_supplicant cases and not from the
driver.

If a new connection is attempted while there is a pending sme-connection
radio work, cancel the pending radio work and continue with the new
connection attempt. This is preferable over rejecting the new work and
continuing with the pending one, as it is possible that the previous
work is no longer valid.

This makes it easier to debug wpa_supplicant behavior when reporting
20/40 MHz co-ex information based on OBSS scans.
Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
The 40 MHz intolerant bit needs to be checked before skipping the BSS
based on the channel already being in the lost (which could have
happened due to another BSS that does not indicate 40 MHz intolerant).
This fixed the 20/40 MHz co-ex report to indicate 20 MHz request
properly if there are both 40 MHz tolerant and intolerant BSSes on the
same channel.

The HS 2.0 Indication element from wpa_supplicant now includes the
release number field and wpa_supplicant shows the release number of the
AP in STATUS command (hs20=1 replaced with hs20=<release>).
The new update_identifier field in the cred block can now be used to
configure the PPS MO ID so that wpa_supplicant adds it to the Indication
element in Association Request frames.

It was possible for the connect or sme-connect radio work to get
re-scheduled while an earlier request was still pending, e.g.,
select_network is issued at the moment a scan radio work is in progress
and the old scan results are recent enough for starting the connection.
This could result in unexpected attempt to re-associate immediately
after completing the first connection.

While testing rfkill blocking of a scanning interface, it
was seen that the ongoing scan never completes. This happens
since EVENT_SCAN_RESULTS is discarded on a disabled interface.
Fix this and also other possible radio work completion issues
by removing all the radio works (including started) of the
disabled interface.
To be able to remove already started radio works, make their
callbacks be reentrant with deinit flag (when the work
is started), so each radio work should be able to handle
its own termination.

Commit 6ac4b15ef8 (wpa_radio work for
connection) caused a regression for cases where multiple auth_alg values
are set in a network block and wpa_supplicant-based SME is supposed to
iterate through them. The connection radio work was not terminated when
receiving authentication failure and this resulted in the following
authentication attempt failing.

WPA_CIPHER_* and CIPHER_* are used for the exact same set of cipher
suites with the main difference being that the WPA_CIPHER_* version is
suitable to be used as a bitfield. Similarly, WPA_KEY_MGMT_* and
KEY_MGMT_* have similar design for AKMs. There is no need to maintain
two separate copies of the definitions since the bitfield compatible
version can be used for both needs. Get rid of the CIPHER_* and
KEY_MGMT_* versions to clean up the implementation by getting rid of
unnecessary mapping functions.

Number of regressions had shown up in wpa_supplicant implementation of
SAE group selection due to different integer array termination (-1 in
hostapd, 0 in wpa_supplicant) being used for SAE groups. The

In addition, the sae_group_index was not cleared back to 0 properly

The Hotspot 2.0 specification seems to mandate this element to be
included in all (Re)Association Request frames if the station is Hotspot
2.0 capable. However, that results in conflicts with other requirements
like no TKIP use when this element is present. The design is really
supposed to include the indication element only for Hotspot 2.0
associations regardless of what the current specification implies.
Remove the HS 2.0 Indication element from (Re)Association Request frame
whenever the connection is not for Hotspot 2.0 purposes.

The unprotected disconnection events were previously processed only for

Some of the authentication/association failure paths left wpa_state to
its previous value. This can result in unexpected behavior when
wpa_supplicant tries to find an AP to connect to since the uncleared
state can result the in the selected BSS being ignored if it is same as
the previously used BSS. This could happen, e.g., when wpa_supplicant
SME was used and the AP rejected authentication. Fix this by explicitly
setting state to DISCONNECTED on auth/assoc failures that did not yet do
this.
