NL80211_CMD_GET_KEY response may return the actual key in addition to

Explicitly clear the message payload with the possibly included key
material from heap memory before returning from the handler function
(and having libnl free the nlmsg) when key information is obtained from
the driver using the NL80211_CMD_GET_KEY command.

wpa_s->p2p_go_do_acs was not cleared during P2P group deletion and that
resulted in the case of no separate group interface continuing to assume
ACS was to be used for consecutive GO starts even if they tried to
specify a frequency. Fix this by explicitly clearing
wpa_s->p2p_go_do_acs during P2P group deletion and also clear this when

The configurated fragmentation/RTS threshold value survives AP mode
interface restarts, so these values need to be explicitly cleared back

example, this combination used to fail:

hostapd configuration parameters fragm_threshold and rts_threshold were
documented to disable the threshold with value -1 and not change driver
configuration if the parameter is not included. However, -1 was mapped
into not changing the driver value, so the explicit disabling part did
not work.
Replace the default values for these to be -2 so that explicitly set
configuration value -1 can be distinguished from the case of not
including the parameter. Map the -1 value to a driver request to disable
the threshold. Ignore any error from this operation just in case to
avoid breaking functionality should some drivers not accept the (u32) -1
value as a threshold value request to disable the mechanism.

The first scan for the unknown BSSID could have been timed in a manner
that allows passive scanning to find the real AP even if that AP's
beacon interval was 1000 (e.g., heavy CPU load changed timing so that
the AP beaconing started at suitable time). The check for BSS result
entry not including Probe Response frame was comparing incorrect BSS
entries (bss2 vs. bss1) which resulted in the test case claiming failure
even when there was no unexpected Probe Response frame.
Fix this by comparing the beacon_ie and ie parameters from the same BSS
entry (bss1).

Number of these test cases start connection attempt in wpa_supplicant
and then expected a specific failure to happen relatively quickly. This
could result in timeouts if the first scanning round missed to find the
AP (e.g., due to CPU load pushing out the Probe Response frame long
enough for the station having left the channel) and wpa_supplicant then
waiting five seconds before starting a new scan.
Make this more robust by scanning explicitly for the specific BSSID
before starting the connection attempt.

This patch added 'check_cert_subject' support to match the value of
every field against the DN of the subject in the client certificate. If
the values do not match, the certificate verification will fail and will
reject the user.
This option allows hostapd to match every individual field in the right
order, also allow '*' character as a wildcard (e.g OU=Development*).
Note: hostapd will match string up to 'wildcard' against the DN of the
subject in the client certificate for every individual field.

Include only one of hostapd_mgmt_rx() and hostapd_action_rx() functions
in the build. Previously, NEED_AP_MLME builds (i.e., cases where hostapd
AP MLME implementation is included) included both of these functions and
both were tried in sequence. In addition to being difficult to
understand, that could result in unexpected behavior if
hostapd_mgmt_rx() rejected a frame and return 0 to allow
hostapd_action_rx() to attempt to process the frame.
All the operations included in hostapd_action_rx() are supposed to be
available through the hostapd_mgmt_rx() call in handle_action() and
those should result in the exact same Category/Action-based handler
function to be called in the end. As such, this should not result in
different behavior. And if there is a difference, that would be pointing
at a hidden bug that would need to be fixed anyway. Furthermore, builds
without NEED_AP_MLME would not have any difference in behavior or
contents of the binary either.

Signed-off-by: Jouni Malinen <j@w1.fi>
hostapd_action_rx() was pointing at incorrect field (Action vs.
Category) for the wpa_ft_action_rx() call and the length check for SA
Query Action frames. This resulted in those frames getting dropped as
invalid (FT) or ignored as truncated (SA Query). Fix this by pointing to
the correct place at the beginning of the frame body.
This issue had a long history. These were broken during cleanup in
commit dbfb8e82ff ("Remove unnecessary EVENT_RX_ACTION") which
actually fixed the initial reason for the error accidentally. It was
just that that error was needed to cancel out another earlier error..
One of the errors came from misuse of the EVENT_RX_ACTION API in commit
deca6eff74 ("atheros: Add new IEEE 802.11r driver_ops"). That pointed
struct rx_action data/len to cover the Action frame from the Category
field to the end of the frame body while the API was documented to cover
Action field to the end of the frame body. This error was cancelled by
another error in commit 88b32a99d3 ("FT: Add FT AP support for drivers
that manage MLME internally") that called wpa_ft_action_rx() with the
struct rx_action::data field as the second argument. That argument needs
to point to the Category field, but that struct rx_action field was
supposed to point to the Action field.
Number of the Action frame handlers added into hostapd_action_rx() had
been fixed more or less accidentally after this in various other
commits, but the FT and SA Query handlers had ended up maintaining the
incorrect operations. This is now fixing those.
This seems to fix at least some cases of FT-over-DS with drivers that
use driver-based AP MLME. Such drivers might use internal SA Query
processing, so it is not clear whether that part actually fixes any real
issues.

Copy the Finite Cyclic Group field value from the request to the
response Authentication frame if we end up rejecting the request due to
unsupported group.
IEEE Std 802.11-2016 has conflicting statements about this behavior.
Table 9-36 (Presence of fields and elements in Authentication frames)
indicates that the Finite Cyclic Group field is only included with
status code values 0 (success) and 76 (anti-clogging token request)
while SAE protocol description implying that the Finite Cyclic Group
field is set to the rejected group (12.4.8.6.3 and 12.4.8.6.4).
The standard language needs to cleaned up to describe this
unambiguously, but since it looks safe to add the field into the
rejection case and since there is desire to have the field present to be
able to implement what exactly is stated in 12.4.8.6.4, it looks
reasonable to move ahead with the AP mode implementation change. There
is no change in wpa_supplicant for now to modify its behavior based on
whether this field is present, i.e., wpa_supplicant will continue to
work with both the old and new hostapd behavior for SAE group
negotiation.

Do not start SAE authentication from scratch if a STA starts a new
attempt for the same group while we still have previously generated PWE
available. Instead, use the previously generated PWE as-is and skip
anti-clogging token exchange since the heavy processing is already
completed. This saves unnecessary processing on the AP side in case the
STA failed to complete authentication on the first attempt (e.g., due to
heavy SAE load on the AP causing a timeout) and makes it more likely for
a valid STA to be able to complete SAE authentication during a DoS
attack.
