If a sniffer capture does not include FCS for each frame, but may
included frames with invalid FCS, it would be possible for wlantest to
try to decrypt the first received frame and fail (e.g., due to CCMP MIC
mismatch) because that particular frame was corrupted and then ignore
the following retry of that frame as a duplicate even if that retry has
different payload (e.g., if its reception did not show corruption).
Work around this by skipping duplicate frame detection immediately
following a decryption failure.

sscanf() can apparently read beyond the end of the buffer even if the
maximum length of the integer is specified in the format string. Replace
this parsing mechanism with helper functions that use sscanf() with NUL
terminated string to avoid this.

src/*/Makefile needs to allow additional CFLAGS values to be provided
from the calling Makefiles so that the clang command line arguments to
enable sanitizers consistently. In addition, it can be useful to be able
to provide CC, CFLAGS, and LDFLAGS from external setup while still
requesing LIBFUZZER=y build. Allow that by not overriding these
variables if they are already set.

This struct needs to remain valid through the lifetime of the
authenticator state machine, so move it to the context struct instead of
being a local stack variable inside the setup function that returns
before the actual test functionality is executed.

The driver automatically starts beacon reporting if it pauses the beacon
reporting for any reason other than disconnection. In specific cases,
userspace may not want the beacon reporting to be automatically resumed
after a pause. Add interface support for userspace to specify driver not
to start beacon reporting automatically after a pause.

It is safer to maintain the old EAPOL version (2) in EAPOL frames that
are not related to MACsec and only update the version to 3 for the
MACsec specific cases.

Looks like the previous fix for a newer OpenSSL versions broke
functionality with older versions that did not seem to like @SECLEVEL=0
in the cipher list. Make that addition conditional on OpenSSL version to
work with both versions.

SIM-based EAP authentication with IMSI encryption requires a special EAP
Identity response: anonymous@realm. Then the server sends AKA-Identity
request which is answered with the encrypted IMSI. Add logic that
indicates if the special anonymous identity is used. Otherwise, this
field is used for storing the pseudonym.
Test: Connect to Carrier Wi-Fi, verify correct behavior from captures
Test: Connect to non IMSI encrypted EAP-AKA AP, verify pseudonym usage

External auth status to the driver includes the PMKID derived as part of

A driver that uses internal AP SME may need to be able to use the
external_auth status operation in station mode, so do not skip this
solely based on drv->device_ap_sme; instead, use that condition only
when operating in AP mode.

With radio work design, send Action frame request will be queued and
wait for p2p-scan to finish, so there is no need to delay send_action.
This change revisits the logic (added before the radio work framework)
in below commits:
3f9285f P2P: Delay send_action call if p2p_scan is in progress
f44ae20 P2P: Drop pending TX frame on new p2p_connect
9d562b7 P2P: Add p2p_unauthorize command
63a965c P2P: Fix after_scan_tx processing during ongoing operations
9a58e52 P2PS: Callback to create pending group after sending PD Response

This increases the priority of the p2p-send-action radio work, i.e., the
radio work used for transmitting potentially offchannel P2P Action
frames by marking it as the next radio work to execute. This is to avoid
the delay in transmissions due to already queued offchannel radio work
items in the queue. In particular, this means not having to wait for a
pending p2p-scan radio work to be executed before the new P2P Action
frame can be transmitted. This helps in avoiding timeouts on the peer
device when a P2P Action frames is received during other activity on the
device.

The previous implementation rejects the p2p-send-action work while there
is already one in progress (wpas_send_action_cb() has already been
called for it to start operation). Enhance the same to also consider any
p2p-send-action works pending in the radio work (i.e., waiting for that
wpas_send_action_cb() call).
This is considering the current behaviour of P2P to handle the state
corresponding to respective Action frame transmission:
pending_action_state. If a new P2P Action frame transmission is queued
while there is another one already in the queue, the transmit status of
the first frame is wrongly intepreted by the P2P state machine which has
already scheduled/queued another frame for transmission.

If an AP rejects association due to low RSSI, then RSSI of the BSS from
which association reject is received shall be used for calculating RSSI
threshold at which STA can try connecting back to that BSS later. In
case of SME offload, the current_bss might not have been set before
receiving association completion, so fetch the BSS entry based on the
BSSID provided in the driver event.

It looks like the previously used sleep time was not sufficient to allow
capturing the frames from wlan0/wlan1/wlan2 to start and complete so
that all the necessary frames can be checked. This was the case
especially with UML time-travel=inf-cpu.
