While RFC 6124 does not define how Session-Id is constructed for

the following email:
From: Yaron Sheffer <yaronf.ietf at gmail.com>
To: ietf at ietf.org
Date: Wed, 17 Nov 2010 13:13:42 +0200
Expanding on my previous response, I suggest to resolve Bernard's
concern by adding the following text:
5.6 EAP Key Generation
EAP-EKE can be used for EAP key generation, as defined by [RFC 5247].
When used in this manner, the values required to establish the key
hierarchy are defined as follows:
- Peer-Id is the EAP-EKE ID_P value.
- Server-Id is the EAP-EKE ID_S value.
- Session-Id is the concatenated Type | Nonce_P | Nonce_S, where Type is
the method type defined for EAP-EKE in [Sec. 4.1], a single octet.
Thanks,

The req_plen argument to eap_pax_process_std_1() and
eap_pax_process_std_3() could be smaller than sizeof(struct eap_pax_hdr)
since the main processing function was only verifying that there is
enough room for the ICV and then removed ICV length from the remaining
payload length.
In theory, this could have resulted in the size_t left parameter being
set to a negative value that would be interpreted as a huge positive
integer. That could then result in a small buffer read overflow and
process termination if MSGDUMP debug verbosity was in use.
In practice, it does not seem to be feasible to construct a short
message that would be able to pass the ICV validation (calculated using
HMAC-SHA1-128) even for the case where an empty password is used.
Anyway, the implementation should really check the length explicitly

Currently, vlan_remove_dynamic() is only called when the station VLAN ID
is changed (ap_sta_bind_vlan), but not when the station is freed. So
dynamic VLAN interfaces are not removed actually except within 1x
reauthentification VLAN ID change, although most of the code is already
there.
This patch fixes this by calling vlan_remove_dynamic() in ap_free_sta().
It cannot just use sta->vlan_id for this, as this might have been
changed without calling ap_sta_bind_vlan() (ap/ieee802_11.c:handle_auth
fetches from RADIUS cache for WPA-PSK), thus reference counting might
not have been updated. Additionally, reference counting might get wrong
due to old_vlanid = 0 being passed unconditionally, thus increasing the
reference counter multiple times.
So tracking the currently assigned (i.e., dynamic_vlan counter
increased) VLAN is done in a new variable sta->vlan_id_bound. Therefore,
the old_vlan_id argument of ap_sta_bind_vlan() is no longer needed and
setting the VLAN for the sta in driver happens unconditionally.
Additionally, vlan->dynamic_vlan is only incremented when it actually
is a dynamic VLAN.

hostapd deletes the AP_VLAN interface and then recreates it. Thus the
kernel assigns the same ifidx to the new interfaces and sends DELLINK

As the DELLINK messages are processed after the struct hostapd_vlan is
added, hostapd deletes the struct hostapd_vlan entry, deconfigures the
AP_VLAN interface and leaves vlan_newlink nothing to find afterwards.
So this patch makes DELLINK messages to be ignored when the interface

Both Android's libc and glibc support _FORTIFY_SOURCE, a compiler
and libc feature which inserts automatic bounds checking into
common C functions such as memcpy() and strcpy(). If a buffer
overflow occurs when calling a hardened libc function, the
automatic bounds checking will safely shutdown the program and
prevent memory corruption.
Android is experimenting with _FORTIFY_SOURCE=3, a new fortify
level which enhances memcpy() to prevent overflowing an element
of a struct. Under the enhancements, code such as
struct foo {
char empty[0];
char one[1];
char a[10];
char b[10];
};
int main() {
foo myfoo;
int n = atoi("11");
memcpy(myfoo.a, "01234567890123456789", n);
return 0;
}
will cleanly crash when the memcpy() call is made.
Fixup hostap code to support the new level. Specifically:
* Fixup sha1_transform so it works with the enhanced bounds checking.
The old memcpy() code was attempting to write to context.h0, but that
structure element is too small and the write was extending (by design)
into h1, h2, h3, and h4. Use explicit assignments instead of
overflowing the struct element.
* Modify most of the structures in ieee802_11_defs.h to use ISO C99
flexible array members (https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html)
instead of a zero length array. Zero length arrays have zero length,
and any attempt to call memcpy() on such elements will always overflow.
Flexible array members have no such limitation. The only element not
adjusted is probe_req, since doing so will generate a compile time error,
and it's not obvious to me how to fix it.

The new network profile parameter mem_only_psk=1 can be used to specify
that the PSK/passphrase for that network is requested over the control
interface (ctrl_iface or D-Bus) similarly to the EAP network parameter
requests. The PSK/passphrase can then be configured temporarily in a way
that prevents it from getting stored to the configuration file.
For example:
Event:
CTRL-REQ-PSK_PASSPHRASE-0:PSK or passphrase needed for SSID test-wpa2-psk
Response:
CTRL-RSP-PSK_PASSPHRASE-0:"qwertyuiop"
Note: The response value uses the same encoding as the psk network
profile parameter, i.e., passphrase is within double quotation marks.

Commit e6dd8196e5 ('Work around Linux
packet socket regression') closed the workaround socket on the first
received EAPOL frame from the main packet socket. This can result in
closing the socket in cases where the kernel does not really work in the
expected way during the following initial association since
reauthentication/rekeying using EAPOL frames happens while operstate is
not dormant and as such, the frames can get delivered through the main
packet socket.
Fix this by closing the workaround socket only in case the first EAPOL
frame is received through the main packet socket. This case happens
while the interface is in dormant state and as such, is more likely to
show the more restricted case of kernel functionality.
In order to avoid processing the received EAPOL frames twice, verify a
checksum of the frame contents when receiving frames alternatively from
the main packet socket and the workaround socket.

This modifies the BSS selection routines to calculate SNR and estimated

taking into account higher throughput rates if both the AP and local
device supports HT20, HT40, or VHT80. In addition, the maximum rate is

In practice, this gives significantly higher probability of selecting

It is possible for an Action frame TX operation to be stopped in a way

This could result in reception of a fragmented service discovery
response failing due to the GAS sequence getting stopped when receiving
TX callback for the first GAS comeback request. That sequence could be

STA expiration:
(current jiffies) > (frame Rx jiffies + NL80211_MESHCONF_PLINK_TIMEOUT * 250)
On a 32 bit system, the right side could overflow and be unexpected
small value if NL80211_MESHCONF_PLINK_TIMEOUT is sufficiently large. STA
expiration occurs by this reason.
This patch solves the problem by disabling the STA expiration
functionality in mac80211. However, old kernel does not support
disabling it. If so, this patch sets mac80211 inactivity timer 60

Previously, a channel with even a single scan/survey result missing
information was skipped in ACS. This may not be desirable in cases when
multiple scan iterations are used (which is the case by default in
hostapd). Instead, use all channels that provided at least one complete
set of results. Calculate the average interference factor as an average
of the iterations that did provide complete values.
This seems to help with some cases, e.g., when ath9k may not be able to
report the noise floor for all channels from the first scan iteration
immediately after the driver has been loaded, but then returns it for

The new acs_chan_bias configuration parameter is a space-separated list
of <channel>:<bias> pairs. It can be used to increase (or decrease) the
likelihood of a specific channel to be selected by the ACS algorithm.
The total interference factor for each channel gets multiplied by the
specified bias value before finding the channel with the lowest value.
In other words, values between 0.0 and 1.0 can be used to make a channel
more likely to be picked while values larger than 1.0 make the specified
channel less likely to be picked. This can be used, e.g., to prefer the
commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).

The interference factors for adjacent 2.4 GHz channels were summed
together without doing any kind of weighted average on them. This
resulted in the channels at the band edges getting undue preference due
to only including interference factors from three channels vs. five for
the channels in the middle of the band.
While it is somewhat unclear whether the design here was supposed to
count overlapping channels together in this way or whether that is
already covered in channel survey results, it is clear that this summing
of three to five values together and then comparing the sum rather than
average of some kind gives too much preference to the channels at the
edges of the band by assuming that there is no interference whatsoever
outside the band.
Use weighted average of the interference factors rather than a sum from
different number of values. For now, the adjacent 2.4 GHz channels get
weight of 0.85 (1.0 for the main channel itself) and the neighboring
channels to those adjacent ones get 0.55 weight. Band-edge channels are
handled in a way that takes average over the channels that were actually
considered instead of assuming zero interference from neighboring bands.

Since we do not currently support AP doing OBSS scans after the initial

For wired IEEE 802.1X authentication, phase1="allow_canned_success=1"
can now be used to configure a mode that allows EAP-Success (and
EAP-Failure) without going through authentication step. Some switches
use such sequence when forcing the port to be authorized/unauthorized or
as a fallback option if the authentication server is unreachable. By
default, wpa_supplicant discards such frames to protect against
potential attacks by rogue devices, but this option can be used to
disable that protection for cases where the server/authenticator does
not need to be authenticated.
When enabled, this mode allows EAP-Success/EAP-Failure as an immediate
response to EAPOL-Start (or even without EAPOL-Start) and EAP-Success is
also allowed immediately after EAP-Identity exchange (fallback case for
authenticator not being able to connect to authentication server).

wpa_supplicant used to request user to re-enter username/password if the
server indicated that EAP-MSCHAPv2 (e.g., in PEAP Phase 2)
authentication failed (E=691), but retry is allowed (R=1). This is a
reasonable default behavior, but there may be cases where it is more
convenient to close the authentication session immediately rather than
wait for user to do something.
Add a new "mschapv2_retry=0" option to the phase2 field to allow the
retry behavior to be disabled. This will make wpa_supplicant abort
authentication attempt on E=691 regardless of whether the server allows
retry.

Linux kernel commit 576eb62598f10c8c7fd75703fe89010cdcfff596 ('bridge:
respect RFC2863 operational state') from 2012 introduced a regression
for using wpa_supplicant with EAPOL frames and a station interface in a
bridge. Since it does not look like this regression is going to get
fixed any time soon (it is already two years from that commit and over
1.5 from a discussion pointing out the regression), add a workaround in
wpa_supplicant to avoid this issue.
The wpa_supplicant workaround uses a secondary packet socket to capture
all frames (ETH_P_ALL) from the netdev that is in a bridge. This is
needed to avoid the kernel regression. However, this comes at the price
of more CPU load. Some of this is avoided with use of Linux socket
filter, but still, this is less efficient than a packet socket bound to
the specific EAPOL ethertype. The workaround gets disabled
automatically, if the main packet socket interface on the bridge
interface turns out to be working for RX (e.g., due to an old kernel
version being used or a new kernel version having a fix for the
regression). In addition, this workaround is only taken into use for the
special case of running wpa_supplicant with an interface in a bridge.

Commit 587d60d2b7 ('Add AP mode support

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

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

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

Suppose there are two APs (AP1 & AP2) and user attempted to connect to
AP2 before the previous connection with AP1 could succeed. Now, if the
connection event comes for the older AP with failed status, we should
just ignore it as the wpa_supplicant state has moved to "ASSOCIATING"
with the new AP (AP2).
This is a similar to the case where a disconnection event is ignored for
a case where local disconnect request can cause the extra event to show
up during the next association process following that command.

Previously, it was possible for the loop through the data components to
increment addr/len index at the last position beyond the declared size.
This resulted in reading beyond those arrays. The read values were not
used and as such, this was unlikely to cause noticeable issues, but
anyway, memory checkers can detect this and the correct behavior is to
stop increments before going beyond the arrays since no more bytes will
be processed after this anyway.

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.

(AES-128-CMAC) for EAPOL-Key frames when version 2 (HMAC-SHA1) was

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

p2p->go_neg_peer, so there is no need for that argument to be there. In
addition, p2p->go_neg_peer is not NULL in cases where there is an
ongoing GO Negotiation, so the function can be simplified to just check
once whether the peer pointer is set and if not, skip all processing.
Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
The timeout check while waiting for the peer to accept the GO
Negotiation depended on the WAIT_PEER_IDLE or WAIT_PEER_CONNECT states
being in use. Any P2P command to alter such states would have resulted
in the failure to time out GO Negotiation and thus ended up in not
indicating GO Negotiation failure or left the selected peer available
for new GO negotiation after the expected two minute timeout.
Fix this by using a separate timer to time out GO Negotiation
irrespective of the P2P state.

Commit b41f26845a ('Add support for
offloading key management operations to the driver') used incorrect
variable for determining the KCK length. This does not get triggered in
normal use cases since KCK and KEK are always included and of the same
length (in currently supported key management cases). Anyway, this needs
to be fixed to check the correct attribute. (CID 74491)

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
resides in the kernel bridge code, in order to optimize the performance
and simplify kernel implementation, the DHCP snooping code was added to
the hostapd.

Commit 7139cf4a4f ('P2P: Decrement

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).

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.

Previously, extra connect/roam events were ignored when user space SME
was used to avoid confusing double events for association. However,
there was no matching code for ignoring auth/assoc events when using
driver SME. Such events would not normally show up since the driver SME
case would not generated them. However, when testing forced connect
command with force_connect_cmd=1 driver param, these events are
indicated.
Ignore the extra events in testing cases to make the hwsim test cases
match more closely the real code path for driver SME. In addition, this
resolves some test case failures where double association event could
end up causing a failure, e.g., when doing PMKSA caching in
pmksa_cache_oppurtunistic_connect.

If a TX status event and RX event for a GO Negotiation frame gets
delayed long enough to miss the initial wait, it was possible for
reception of a GO Negotiation Response frame with status 1 to try to
initiate a new p2p-listen work item to wait for the peer to become ready
while a previous p2p-listen was already in progress due to that earlier
timeout while waiting for peer. This would result in the new
start_listen request getting rejected ("P2P: Reject start_listen since
p2p_listen_work already exists") and the negotiation not proceeding.
Work around this by using P2P_WAIT_PEER_CONNECT state instead of
P2P_WAIT_PEER_IDLE if P2P_CONNECT_LISTEN state has already been entered
when processing this special GO Negotiation Response status=1 case. This
can avoid double-scheduling of p2p-listen and as such, completion of the
GO negotiation even if the driver event or peer response are not
received in time (the response is supposed to be there within 100 ms per
spec, but there are number of deployed devices that do not really meet
this requirement).

Previously, the shorter startWhen value was used based on build
parameters (i.e., if WPS was enabled). This is not really ideal and the
knowledge of WPS use can be provided to the EAPOL state machine to allow
this (and similar WPS workarounds) to be done only when the association
is for the purpose of WPS.
Reduce the default startWhen value from 3 to 2 seconds for non-WPS case

with the 1 second value and there is no strong justification for forcing
the longer 3 second wait should a frame be lost or something else

Performing a P2P Device flow such as p2p_listen or

connection, if the listen frequency is different than the

To reduce the effect of P2P Device flows on other interfaces,
try changing the listen channel of the P2P Device to match the
operating channel of one of the other active interfaces. This change
will be possible only in case that the listen channel is not forced

In addition, make the newer set_ap() driver_ops use the same bitwise OR
design instead of picking between rsn_pairwise and wpa_pairwise. This

dying either due to buffer overflow protection or by a read from
unallowed address.

interface use cases should not actually use this. This could result in

It is possible for a virtual interface to be added and removed by
different parent interfaces. This can happen, e.g., with P2P group
interfaces if the P2P parent interface does not happen to be the first
entry in the wpa_supplicant global interface list. That first entry is
used to remove the group interface while the addition would have
happened with the dedicated P2P management interface.
This can result in the interface that added a new virtual interface
getting stuck with an obsolete ifindex value in the drv->if_indeces list
and as such, deliver some extra events to incorrect destination wpa_s
instance. In particular, this can result in INTERFACE_DISABLED event
from deletion of a P2P group interface getting delivered incorrectly to
the parent wpa_s instance which would disable that interface even though
the interface remains in enabled state.
Fix this by clearing the removed interface from all if_indeces lists
instead of just the one that was used to delete the interface. This is
the simplest approach since the ifindex is unique and there is no need
to track which interface added the new virtual interface to always hit
the same one when removing the interface.

"dispatch fd" is dispatchment of fds by eloop_sock_table_dispatch().
"N" is all watching fds.
"M" is fds which could be dispatched after waiting.
As shown in Table1, epoll option has better performance on "prepare fd" column.
Because select/poll option requires setting fds before every select()/poll().
But epoll_wait() doesn't need it.
And epoll option has also better performance on "dispatch fd" column.
Because select/poll option needs to check all registered fds to find out

Because epoll_wait() returns dispatchable fd set.

examine the channels of the current operational regulatory domain to
determine whether the operation of a 20/40 MHz BSS might unfairly
interfere with the operation of existing 20 MHz BSSs. The AP (or some of
its associated HT STAs) is required to scan all of the channels of the
current regulatory domain in order to ascertain the operating channels
of any existing 20 MHz BSSs and 20/40 MHz BSSs. (IEEE 802.11-2012 S.5.2
Establishing a 20/40 MHz BSS).
Add the check for an overlapping 20 MHz BSS to the initial AP scan for
the P == OT_i case in 10.15.3.2.

scard_gsm_auth() used SIM_CMD_GET_RESPONSE for both SIM and USIM. Convert
the command into USIM_CMD_GET_RESPONSE for USIM.
Since commit eb32460029 ("Fix switching from EAP-SIM to EAP-AKA/AKA'")
EAP-SIM is using the USIM if available. This triggers a probably ancient
bug in scard_gsm_auth(), which results in sending the wrong get response
command to the USIM. Thus, EAP-SIM stopped to work after this change on
USIMs that expect the proper command.

Peer should handle a GO Negotiation exchange correctly when the
responding device does not have WSC credentials available at the
time of receiving the GO Negotiation Request. WSC Credentials
(e.g., Pushbutton) can be entered within the 120 second timeout.
Presently, if concurrent session is not active, the peer would wait for
GO Negotiation Request frame from the other device for approximately one
minute due to the earlier optimization change in commit
a2d6365760. To meet the two minute
requirement, replace this design based on number of iterations with a
more appropriate wait for the required number of seconds.

bss->freq was not updated for IBSS, so whatever old value was stored
from a previous AP mode operation could end up having been used as the
channel when trying to send Authentication frames in an RSN IBSS. This
resulted in the frame not sent (cfg80211 rejects it) and potentially not
being able to re-establish connection due to 4-way handshake failing
with replay counter mismatches. Fix this by learning the operating
channel of the IBSS both when join event is received and when a
management frame is being transmitted since the IBSS may have changed

It can be added back if support for remote ANQP server is added at some
point.

When wpa_psk_file is used instead of wpa_psk/wpa_passphrase, each WPS
Enrollee was given a unique PSK. This did not work for the
station-as-Registrar case where ER would learn the current AP settings
instead of enrolling itself (i.e., when using the AP PIN instead of
station PIN). That case can be covered with a similar design, so
generate a per-device PSK when building M7 as an AP in wpa_psk_file
configuration.

hostapd DEAUTHENTICATE and DISASSOCIATE control interface commands
accepted both a test=<0/1> and reason=<val> parameters, but these were
not supported in the same command as a combination. Move the code around
a bit to allow that as well since it can be helpful for automated test
scripts.

TDLS Setup Request/Response frames from the peers include the WMM IE,
hence parse the same and consider the QoS Info from the WMM IE. The
qos_info obtained in the WMM IE overwrites the one obtained through
WLAN_EID_QOS attribute.

p2p_find removes P2P_DEV_REPORTED flag from every existing P2P peer
entry. Thus, if a GO Negotiation Request frame is received before the
peer is re-discovered based on Probe Response frame, report
P2P-DEVICE-FOUND indication prior to the P2P-GO-NEG-REQUEST similarly to
how this is done the first time the peer is found.

Previously, some of the last initialization steps could fail without
clearly marking the interface disabled. For example, configuring the
channel to the driver could fail, but hostapd would not clearly identify
as the interface not being in functional state apart from not moving it
to the ENABLED state. Send an AP-DISABLED event and mark interface state
DISABLED if such a setup operation fails.
