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.

Now that parallel-vm.py is actually stopping VMs as soon as they are not
needed for retries, it is not really an unexpected exit to see a VM exit
while test cases remain in the queue as long as at least that many VMs
remain running. Get rid of confusing 'unexpected exit' status from the

Now that wpa_supplicant was modified to use NAI realm query even if
roaming_consortium is set, this test case is actually able to find a
match. Update it to avoid cause incorrect test failures.
Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
Previously ANQP fetch considered NAI realm query only when cred block
did not specify roaming_consortium to optimize ANQP operations (NAI
realm list can have a very long value). In certain cases, both NAI realm
and roaming_consortium are configured in credential block and this
resulted in ANQP fetch for NAI realm not being initiated. That could
result in not being able to select the highest priority available
credential/network.
Remove roaming_consortium check for NAI realm query inclusion in ANQP
request so that we will request NAI realm information whenever it can
result in matching additional networks. This makes the ANQP queries more
costly in some cases, but the additional information is needed for
correct behavior in network selection.

Commit 947b5a1532 ("P2P: Stop listen state if Action frame TX is
needed on another channel") added an optimization for P2P response
transmission in certain concurrent operation cases. However, it did not
take into account possibility of the driver not being in listen
state (p2p->drv_in_listen == 0) and could end up getting stuck with the
P2P state machine in a manner that made the device not listen for
following messages. This showed up in following manner in the debug log:
P2P: Starting short listen state (state=SEARCH)
P2P: Driver ended Listen state (freq=2437)
process received frame and send a response
P2P: Stop listen on 0 MHz to allow a frame to be sent immediately on 2437 MHz
P2P: Clear timeout (state=SEARCH)
--> state machine stuck
Fix this by adding drv_in_listen > 0 condition for the optimization to
stop the listen operation in send_action() resulting in scheduled TX.

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
(STATUS_INVALID_PMKID) and ended up using the default
(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.

When the P2P management interface is deleted, P2P is then disabled and
global->p2p_init_wpa_s is set to NULL. After that, other interfaces can
still trigger P2P functions (like wpas_p2p_find()) using D-Bus. This
makes wpa_supplicant terminate with SIGSEGV, because it dereferences a
NULL pointer. Fix this by adding proper checks, like it's done with
wpa_cli.

SUITE_B_192 AKM capability was indicated for all devices using the
nl80211 driver (without the QCA vendor specific AKM capability
indication). However, some devices can't handle Suite B 192 due to
insufficient ciphers supported. Add a check for CCMP-256 or GCMP-256
cipher support and only indicate SUITE_B_192 capability when such cipher
is supported. This allows compiling with CONFIG_SUITEB192 and still get
proper response to the 'GET_CAPABILITY key_mgmt' command. Under Android
it can also serve as a dynamic way for HAL to query platform for
WPA3-Enterprise 192-bit support.

Previously, an unexpected SAE commit message resulted in forcing
disconnection. While that allowed recovery by starting from scratch,
this is not really necessary. Ignore such unexpected SAE commit message
instead and allow SAE confirm message to be processed after this. This
is somewhat more robust way of handling the cases where SAE commit
message might be retransmitted either in STA->AP or AP->STA direction.

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.
