When testing SAE reflection, the incoming commit may have the H2E status
code (126) or SAE-PK (127), but the test code in the AP was always
sending back status code 0. The STA would then reject the commit
response due to expecting H2E/SAE-PK status code.
Just reflect the incoming status code so the commit can be rejected
based on the SAE contents regardless of which variant of SAE was used.

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.

Signed-off-by: Andrew Beltrano <anbeltra@microsoft.com>
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.
Fix by using the newly init'ed DPP auth structure for setting global
DPP configurator params.

If reassoc_same_bss_optim=1 is used to optimize reassociation back to

wpa_mic_len() with incorrect PMK length when PMKSA caching was being

Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
While it is appropriate to try to retransmit the event to another
callback URL on a failure to initiate the HTTP client connection, there
is no point in trying the exact same operation multiple times in a row.
Replve the event_retry() calls with event_addr_failure() for these cases
to avoid busy loops trying to repeat the same failing operation.
These potential busy loops would go through eloop callbacks, so the
process is not completely stuck on handling them, but unnecessary CPU
would be used to process the continues retries that will keep failing
for the same reason.

More than about 700 character URL ended up overflowing the wpabuf used
for building the event notification and this resulted in the wpabuf
buffer overflow checks terminating the hostapd process. Fix this by
allocating the buffer to be large enough to contain the full URL path.
However, since that around 700 character limit has been the practical
limit for more than ten years, start explicitly enforcing that as the
limit or the callback URLs since any longer ones had not worked before
and there is no need to enable them now either.

wpa_supplicant disables PMKSA caching with FT-EAP by default due to
known interoperability issues with APs. This is allowed only if the
network profile is explicitly enabling caching with
ft_eap_pmksa_caching=1. However, the PMKID for such PMKSA cache entries
was still being configured to the driver and it was possible for the
driver to build an RSNE with the PMKID for SME-in-driver cases. This
could result in hitting the interop issue with some APs.
Fix this by skipping PMKID configuration to the driver fot FT-EAP AKM if
ft_eap_pmksa_caching=1 is not used in the network profile so that the
driver and wpa_supplicant behavior are in sync for this.

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.
Signed-off-by: Jouni Malinen <j@w1.fi>
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.
