It would be at least theoretically possible for the bridge netdev to
have disappeared at the time hostapd processes the RTM newlink/dellink

returned success before printing the bridge ifname in debug. In
addition, there is not much point trying to add the bridge ifindex into
the list of own ifindexes in case the interface has already been
removed, so skip that part as well.

There is a possible race condition between receiving the
NEW_PEER_CANDIDATE event and the Authentication frame from the peer.
Previously, if the Authentication frame RX event was indicated first,
that frame got dropped silently. Now, this frame is still dropped, but a
copy of it is stored and the frame gets processed on the following
NEW_PEER_CANDIDATE event if that is received for the same peer within

Commit 587d60d2b7 ('Add AP mode support
for HT 20/40 co-ex Action frame') added processing of co-ex report, but
did not include proper bounds checking or IE type checking for the
payload. Furthermore, this was not ready for the possible extensibility
of the 20/40 BSS Coexistence element.
Fix these by checking IE ids for both elements and doing more
apprioriate bounds checking for the element lengths to avoid potentially
reading beyond the frame buffer. Though, the event receive buffer in
both libnl and driver_nl80211_monitor.c is sufficiently large to make it
very unlikely that the maximum read of about 260 bytes beyond the end of
the Action frame would really have any chances of hitting the end of the
memory buffer, so the practical effect of missing bounds checking would
have been possibly accepting an invalid report frame and moving to 20
MHz channel unnecessarily.

Transaction number 2 (confirm) can also have non-zero Status Code to

unnecessarily complex since there is not really a need to use a separate
SSL_CTX to be able to do that. Instead, simply use SSL_set_ssl_method()
to update the ssl_method for the SSL instance. In practice, this commit

adds that single call into tls_connection_set_params() based on EAP-FAST

Commit 35efa2479f ('OpenSSL: Allow TLS

TLSv1_method() to SSLv23_method() to allow negotiation of TLS v1.0,
v1.1, and v1.2.
Unfortunately, it looks like EAP-FAST does not work with this due to
OpenSSL not allowing ClientHello extensions to be configured with
SSL_set_session_ticket_ext() when SSLv23_method() is used. Work around
this regression by initiating a separate SSL_CTX instance for EAP-FAST
phase 1 needs with TLSv1_method() while leaving all other EAP cases
using TLS to work with the new default that allows v1.1 and v1.2 to be
negotiated. This is not ideal and will hopefully get fixed in the future
with a new OpenSSL method, but until that time, this can be used allow
other methods use newer TLS versions while still allowing EAP-FAST to be

Commit ac330cfd87 ('P2P: Reinvite with
social operation channel if no common channels') introduced a mechamisn
to reinvite a peer during a persistent group reinvocation from a GO with
a different operating channel proposal. This mechanism can fail if the
inviting device (GO) ends up getting a retransmitted, duplicated
Invitation Response frame processed second time while waiting for the
response to the retried Invitation Request (using one of the social
channels as the operating channel). IEEE 802.11 duplicate frame
detection mechanisms are supposed to prevent this type of sequence, but
not all drivers support those rules properly for pre-association frames,
including P2P Public Action frames.
Work around this issue by checking that the dialog token in the
Invitation Response frame matches the one from the last Invitation
Request if the special invitation retry mechanism is used. This is safer
to do now than to enable dialog token matching for all invitation cases.

It is possible for unmasking of 11b rates to fail if a P2P group is
terminated while the netdev is down (e.g., due to rfkill block). This
could result in the 11b TX rates being left masked for non-P2P
operations. This would be particularly unfortunate for channel 14 use
since OFDM rates are not allowed on channel 14 and only OFDM rates were
configured P2P. This issue showed up, e.g., when running hwsim test case
rfkill_autogo followed by ap_wps_conf_chan14.
It may be possible to allow the failed operation in cfg80211/mac80211,

Previously, this was implicitly limited by the 16-bit length field to
65535. This resulted in unhelpful static analyzer warnings (CID 62868).
Add an explicit (but pretty arbitrary) limit of 50000 bytes to avoid
this. The actual WSC messages are significantly shorter in practice, but
there is no specific protocol limit, so 50000 is as good as any limit to
use here.

hostapd control interface can now be used to request transmission of a

Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
If the 4-way handshake ends up having to retransmit the EAPOL-Key
message 1/4 due to a timeout on waiting for the response, it is possible
for the Supplicant to change SNonce between the first and second
EAPOL-Key message 2/4. This is not really desirable due to extra
complexities it causes on the Authenticator side, but some deployed
stations are doing this.
This message sequence looks like this:
AP->STA: EAPOL-Key 1/4 (replay counter 1, ANonce)
AP->STA: EAPOL-Key 1/4 (replay counter 2, ANonce)
STA->AP: EAPOL-Key 2/4 (replay counter 1, SNonce 1)
AP->STA: EAPOL-Key 3/4 (replay counter 3, ANonce)
STA->AP: EAPOL-Key 2/4 (replay counter 2, SNonce 2)
followed by either:
STA->AP: EAPOL-Key 4/4 (replay counter 3 using PTK from SNonce 1)
or:
AP->STA: EAPOL-Key 3/4 (replay counter 4, ANonce)
STA->AP: EAPOL-Key 4/4 (replay counter 4, using PTK from SNonce 2)
Previously, Authenticator implementation was able to handle the cases
where SNonce 1 and SNonce 2 were identifical (i.e., Supplicant did not
update SNonce which is the wpa_supplicant behavior) and where PTK
derived using SNonce 2 was used in EAPOL-Key 4/4. However, the case of
using PTK from SNonce 1 was rejected ("WPA: received EAPOL-Key 4/4
Pairwise with unexpected replay counter" since EAPOL-Key 3/4 TX and
following second EAPOL-Key 2/4 invalidated the Replay Counter that was
used previously with the first SNonce).
This commit extends the AP/Authenticator workaround to keep both SNonce
values in memory if two EAPOL-Key 2/4 messages are received with
different SNonce values. The following EAPOL-Key 4/4 message is then
accepted whether the MIC has been calculated with the latest SNonce (the
previously existing behavior) or with the earlier SNonce (the new
extension). This makes 4-way handshake more robust with stations that
update SNonce for each transmitted EAPOL-Key 2/4 message in cases where
EAPOL-Key message 1/4 needs to be retransmitted.

It is possible that a station device might miss an ACK for an
authentication, association, or action frame, and thus retransmit the
same frame although the frame is already being processed in the stack.
While the duplicated frame should really be dropped in the kernel or
firmware code where duplicate detection is implemented for data frames,
it is possible that pre-association cases are not fully addressed (which
is the case at least with mac80211 today) and the frame may be delivered
to upper layer stack.
In such a case, the local AP will process the retransmitted frame although
it has already handled the request, which might cause the station to get
confused and as a result disconnect from the AP, blacklist it, etc.
To avoid such a case, save the sequence control of the last processed
management frame and in case of retransmissions drop them.

It looks like some APs are incorrectly selecting descriptor version 3
(AES-128-CMAC) for EAPOL-Key frames when version 2 (HMAC-SHA1) was
expected to be used. This is likely triggered by an attempt to negotiate
PMF with SHA1-based AKM.
Since AES-128-CMAC is considered stronger than HMAC-SHA1, allow the
incorrect, but stronger, option to be used in these cases to avoid
interoperability issues with deployed APs.
This issue shows up with "WPA: CCMP is used, but EAPOL-Key descriptor
version (3) is not 2" in debug log. With the new workaround, this issue
is ignored and "WPA: Interoperability workaround: allow incorrect
(should have been HMAC-SHA1), but stronger (is AES-128-CMAC), descriptor
version to be used" is written to the log.

Proxy ARP allows the AP devices to keep track of the hardware address to
IP address mapping of the STA devices within the BSS. When a request for
such information is made (i.e., ARP request, Neighbor Solicitation), the
AP will respond on behalf of the STA device within the BSS. Such
requests could originate from a device within the BSS or also from the
bridge. In the process of the AP replying to the request (i.e., ARP
reply, Neighbor Advertisement), the AP will drop the original request
frame. The relevant STA will not even know that such information was
ever requested.
This feature is a requirement for Hotspot 2.0, and is defined in IEEE
Std 802.11-2012, 10.23.13. While the Proxy ARP support code mainly

If both HT and VHT was enabled on AP and channel switch event from the
driver indicated that HT was disabled, VHT was left enabled. This
resulted in the following channel configuration failing. Fix this by
disabling VHT if HT gets disabled.

Advertise static/dynamic SMPS mode support (according to the wiphy
feature bits) and pass the configured smps_mode when starting the AP.

Add smps_modes field, and let the driver fill it with its supported SMPS
modes (static/dynamic). This will let us start an AP with specific SMPS
mode (e.g., dynamic) that will allow it to reduce its power usage.

The previous TX operation could be on another channel if there are
multiple peers with pending SD queries. To avoid failing to send the
following query, stop the last one to allow any Listen channel to be
used for the following query during p2p_find iteration.

Commit 7139cf4a4f ('P2P: Decrement
sd_pending_bcast_queries when sd returns success') added support for
retrying P2P SD queries. However, it did this without limiting how many
retries are allowed. This can result in excessive number of retries if a
peer device does not show up on its Listen channel and there is a
pending SD query to it. Limit the maximum number of SD retries to 100
per p2p_find operation for each peer to avoid unlimited retries.

Commit 7139cf4a4f ('P2P: Decrement
sd_pending_bcast_queries when sd returns success') changed P2P SD
behavior in a way that the P2P search loop ended up in continuing with
the first peer entry until it acknowledged receipt of a pending
broadcast SD request while the previous design went through all peers
once. While it is reasonable to retry SD, getting stuck with the first
peer is not really desirable. Change the p2p_continue_find() loop to
continue from the next peer in each iteration to allow progress through
all peers that have pending operations if any other peer is not
acknowledging frames (e.g., due to not being on Listen channel).

This commit introduces a QCA vendor command and event to provide an
option to use extended versions of the nl80211 connect/roam operations
in a way that allows drivers to offload key management operations to the
driver/firmware.

This avoids an issue where a wpa_supplicant build with CONFIG_P2P=y and
CONFIG_HS20=y ended up processing a P2P SD query twice when operating as
a GO and sending out two replies. Only the P2P SD implementation should
reply to P2P SD query in such a case.

This reverts commit 851b0c5581.
The kernel now has full support for this (and it is turned off
by default for hwsim) so wpa_supplicant should really go back
to autodetecting this so clients don't have to figure out what
to do.
Also add a debug message stating that P2P_DEVICE support is used.

This allows the URL to be passed as a single argument to the program
instead of getting split into multiple by os_exec(). This makes the
operation more robust for cases where the URL could have been received
from an external source and could potentially add extra arguments to the
command line.
In addition, fix the /system/bin/input execution by using system() for
it instead of execv() through os_exec(). /system/bin/input is a script
that execv() won't be able to run. Since the full command line is
specified, system() can be used for this. The keycode is also changed
from 3 to KEYCODE_HOME to make this work with current Android version.

The new "bss_load_update_period" parameter can be used to configure
hostapd to advertise its BSS Load element in Beacon and Probe Response
frames. This parameter is in the units of BUs (Beacon Units).
When enabled, the STA Count and the Channel Utilization value will be
updated periodically in the BSS Load element. The AAC is set to 0 sinze
explicit admission control is not supported. Channel Utilization is
calculated based on the channel survey information from the driver and
as such, requires a driver that supports providing that information for
the current operating channel.

It is now possible to run hwsim_test like data connectivity test through
wpa_supplicant/hostapd control interface if CONFIG_TESTING_OPTIONS=y is
used for the build. Test functionality is enabled/disabled at runtime
with "DATA_TEST_CONFIG <1/0>". The "DATA_TEST_TX <dst> <src> <tos>"
command can be used to request a test frame to be transmitted.
"DATA-TEST-RX <dst> <src>" event is generated when the test frame is
received.
