hostapd control interface can now be used to request transmission of a
BSS Transition Management Request frame to a specified station.
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

The timeout check while waiting for the peer to accept the GO
Negotiation depended on the WAIT_PEER_IDLE or WAIT_PEER_CONNECT states

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

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.

A P2P Client may be able to connect to the GO even if the WPS
provisioning step has not terminated cleanly (e.g., P2P Client does not

This commit addresses the missing part by completing GO side group

cleanly. Also, this commit reorders the STA authorization indications to
ensure that the group formation success notification is given prior to
the first STA connection to handle such scenarios.

Commit 97279d8d (after hostap-2.0) dropped frame events from foreign
addresses. Unfortunately this commit did not handle the case where the
interface's MAC address might be changed externally, which other
wpa_supplicant code already handled. This causes the driver to reject
any MLME event because the address from the event doesn't match the
stale address in the driver data.
Changing an interface's MAC address requires that the interface be
down, the change made, and then the interface brought back up. This
triggers an RTM_NEWLINK event which driver_nl80211.c can use to
re-read the MAC address of the interface.
