ab647ffea7 Add wpa_supplicant Makefile target libwpa_ctrl.a
"make -C wpa_supplicant libwpa_ctrl.a" can now be used to build a static
library that can be linked with external programs using wpa_ctrl.h. This
makes it easier to create a separate library package that does not
depend in any other hostap.git file other than src/common/wpa_ctrl.h and
the libwpa_ctrl.a built with this new make target.

71d77adb6d Update current BSS level when signal change event occurs
When an EVENT_SIGNAL_CHANGE occurs the bgscan is informed about this
change but the new RSSI value is not stored. In consequence, when
roaming candidates are evaluated, the RSSI value of the current BSS used
to compare is an old one obtained during the last scan rather than the
new one given by the signal change event. This leads sometimes to bad
decision when selecting a new BSS for roaming.

This patch solves the issue by updating the current BSS level when
receiving a signal change event in order to have a very up-to-date
current signal value when choosing an new BSS.

f1609f119a wpa_supplicant: Cancel sched_scan when stopping countermeasures
When stopping the TKIP countermeasures, it would be preferable to

f91a512f1f Add INTERWORKING_ADD_NETWORK command
This can be used to provide more control to upper layers on network
blocks generated as part of Interworking network selection.
INTERWORKING_ADD_NETWORK behaves otherwise identically to
INTERWORKING_CONNECT, but it does not request a new connection after
having added the network block and it returns the network id of the
added network.

INTERWORKING_ADD_NETWORK followed by REASSOCIATE would behave more or
less identically to INTERWORKING_CONNECT, but this allows the created
network profile to be modified, if desired, and/or stored externally.
SELECT_NETWORK can also be used with the network id returned from
INTERWORKING_ADD_NETWORK to enforce that specific network profile to be
used for the next connection (though, it should be noted that this
behavior may not meet all Hotspot 2.0 requirements if there were other
enabled networks that could have higher priority).

b0e669beeb P2P: Fix P2P_CONNECT-auto fallback to GO Neg with group interface
If a separate P2P group interface was used, P2P_CONNECT-auto fallback to
GO Negotiation could result in use of freed memory and segmentation
fault. This happened in cases where the peer GO was found in some old
scans, but not in the first scan triggered by the P2P_CONNECT-auto
command ("P2P: Peer was found running GO in older scan -> try to join
the group" shows up in the debug log). In addition, the GO would still
need to reply to PD Request to allow this code path to be triggered.

When five scans for the GO were completed in this sequence, the P2P
group interface was removed as part of falling back to GO Negotiation.
However, that ended up dereferencing the freed wpa_s instance at the end
of scan event processing. Fix this by reordering code a bit and breaking
out from EVENT_SCAN_RESULTS processing if the interface could have been
removed.

bf51f4f82b mesh: Fix remaining BLOCKED state after SAE auth failure
When SAE authentication fails, wpa_supplicant retries four times. If all
the retries result in failure, SAE state machine enters BLOCKED state.
Once it enters this state, wpa_supplicant doesn't retry connection. This
commit allow connection retries even if the state machine entered
BLOCKED state.

There could be an opinion "Is this patch needed? User could know the SAE
state machine is in the BLOCKED mode by MESH-SAE-AUTH-BLOCKED event.
Then user can retry connection. By user action, SAE state machine can
change the state from BLOCKED to another.". Yes, this is a true at the
joining mesh STA. However, a STA that is already a member of existing
mesh BSS should not retry connection because if the joining mesh STA
used wrong password, all the existing STA should do something from UI to
retry connection.

f0d0a5d23b Improve BSS selection with default noise floor values
When noise floor measurements are not available, compute SNR
using default values for the noise floor. This helps steer us
towards 5 GHz BSSes in high signal strength environments.

In more detail...

Existing code prefers a 5 GHz BSS when the 5 GHz BSS's signal
strength is "close" to that of the 2.4 GHz BSS, or when both SNRs
are large. However, the mwifiex driver does not provide noise
floor measurements, so we can't compute SNRs.

Because mwifiex doesn't provide NF measurements, the "large SNR"
code wasn't effective. By using default values for the noise floor,
we can again compute SNRs, and decide that the SNR is high enough
that we shouldn't worry about the exact difference in SNR.

The default noise floor values (one for 2.4 GHz, and one for 5 GHz)
were chosen by measurement in a noisy environment, so they should be
conservative.

Note that while this patch is motivated by mwifiex, it affects
ath9k as well. Although ath9k provides noise floor measurements
in general, it will sometimes fail to provide a measurement for
one or more specific channels.

As a result of this patch, we'll always compare BSSes based on SNR
(either measured or estimated), rather than sometimes comparing
based on signal strength. ("Always" assumes that the
WPA_SCAN_LEVEL_DBM flag is set. It is for mwifiex and ath9k.)

While there:
- fix a whitespace issue (spaces -> tab)
- clean up existing comments
- update dump_scan_res to indicate whether the noise floor is
  measured, or default

7f7bfba919 Add an option allow canned EAP-Success for wired IEEE 802.1X
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).

49fcc32e91 EAP-MSCHAPv2 peer: Add option to disable password retry query
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.

e6dd8196e5 Work around Linux packet socket regression
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

745d93695b mesh: Create new station entry on popen frames
Currently, there is a race in open mesh networks where mesh STA A
receives a beacon from B and sends a peering open frame to initiate
peering. STA B, having not yet received a beacon from A and thus
created the corresponding station entry, will ignore all such open
frames. If the beacon interval is sufficiently long then peering
will not succeed as a result.

In fact B can simply create the station entry when the popen is
received, as is done in Linux's in-kernel MPM, avoiding the issue.

41bff862d9 mesh: Always free the station if peering failed
Previously, we would only free the station entry if a peering close
frame was received (freeing the station entry causes the kernel to
start sending peer candidate events again when suitable beacons are
received, triggering peering or authentication to restart).

The end result is the same in any case regardless of close reason:
if we leave holding state then peering has started again, so go
ahead and remove the station in all cases.

It was possible for interworking_find_network_match() to find a possible

general, but when combined with wpa_supplicant_fast_associate()

to five seconds and a possible stack overflow due to recursion in that
loop.

operations can be completed before going through the scan results again.

For Interworking connection to work, the SSID of the selected BSS needs

scan results to include two BSS entries matching the BSSID when an
earlier scan with that AP has shown a hidden SSID configuration (e.g.,
when running hwsim test cases, but at least in theory, this could happen
with real use cases as well). When that happened, the incorrect BSS
entry may not have included RSN configuration and as such, it would get
rejected for Interworking connection.

Fix this by confirming that the selected BSS entry has a real SSID. If
not, try to find another BSS entry matching the same BSSID and use that,
if found with an SSID.

a156ffda61 Add support for testing memory allocation failures
The new control interface command TEST_ALLOC_FAIL and GET_ALLOC_FAIL can
now be used to trigger memory allocation failures for testing purposes.
TEST_ALLOC_FAIL sets a failure conditions with
<count>:func[;func][;func]... string and GET_ALLOC_FAIL returns the
current state using the same format. Whenever an allocation is made with
a matching backtrace of calling functions, the count is decremented by
one and once zero is reached, the allocation is forced to fail.

Function names can be prefixed with either '=' or '?' to get different
matching behavior. '=' requires this specific function to be the next
one in the backtrace (i.e., do not skip any other functions in the list
which is the default behavior). '?' allows the function to be optionally
present in the backtrace.

os_realloc_array() failed. This resulted in the following

In addition, the separately allocated strings in the array would have

In addition, there is no need to allocate the returned item separately,
so use a single allocation and a pointer to that allocated memory. This
will make it easier for callers to have to free only a single
allocation. This is also fixing a memory leak in P2P invitation

f11e797d4c D-Bus: Avoid valgrind warning due to compiler optimization
It looks like both gcc and clang optimize the (entry.type != foo ||
entry.array_type != bar) in a way that ends up evaluating the second
condition even when the first one results in 0. While this is not really
what the C language requirements on short-circuit evaluation require,
the compiler likely assumes this can have no side effects and with both
type and array_type being comparable in a single 64-bit operation, this
can clearly be a bit more efficient. While the code behaves same in both
cases, valgrind does warn about use of uninitialized memory when the
second condition is evaluated (entry.array_type is not initialized if
entry.type != DBUS_TYPE_ARRAY).

To keep valgrind logs cleaner, initialize entry.array_type to
DBUS_TYPE_INVALID so that these compiler optimizations do not result in
reading uninitialized memory.

b07f1ebe0f D-Bus: Fix .Group Set(WPSVendorExtensions) format
The earlier implementation seemed to require a strange extra
encapsulation with a dictionary for setting the WPSVendorExtensions
property while this was defined to have aay signature and the get
operation did indeed return and array of array of bytes without that
dictionary. Fix this to accept aay format for the setter as well. Keep
support for the old dictionary encapsulation format for backwards

ee82e33d6a Do not trigger the scan during initialization on Android platforms
Android framework maintains a state to process the scan results after
the scan is issued. If wpa_supplicant issues the scan during the
initialization, the one issued by the framework may fail (with EBUSY) if
the host driver is already processing the scan. Thus, the scan results
returned for the first scan triggered by wpa_supplicant are not
processed for getting displayed resulting in delay for the display of
the first scan results after the Wi-Fi subsystem initialization. Thus,
trigger the scan only based on the framework request on Android.

44177b69e8 Allow a BSS entry with all-zeros BSSID to expire
wpa_bss_in_use() used to determine that a BSS with BSSID of
00:00:00:00:00:00 is in use in almost every case since either
wpa_s->bssid or wpa_s->pending_bssid was likely to be cleared. This
could result in a corner case of a BSS entry remaining in the BSS table
indefinitely if one was added there with a (likely bogus) address of
00:00:00:00:00:00. Fix this by ignore wpa_s->bssid and
wpa_s->pending_bssid if the BSSID in the BSS table entry is
00:00:00:00:00:00.

In theory, that address is a valid BSSID, but it is unlikely to be used
in any production AP, so the potential expiration of a BSS entry with
that address during a connection attempt would not be a concern
(especially when a new scan would be enough to recover from that).

a7f5271d52 Update pending connect radio work BSS pointer on scan update
It is possible for scan result processing or BSS entry removal to occur
while there is a pending connect or sme-connect radio work with a
previously selected BSS entry. The BSS pointer was previously verified
to be valid, i.e., still point to a BSS entry, at the time the actual
connection operation is started. However, that BSS entry could have
changed to point to another BSS if the old BSS entry was either removed
or reallocated and a new BSS entry was added at the same location in
memory. This could result in the connection attempt failing to configure
parameters properly due to different BSS information (e.g., different
BSSID).

Fix this by updated the pending connect radio work data on BSS entry
updates similarly to how the last_scan_res array was updated. If the
selected BSS entry is removed, this will still result in a failed
connection, but reallocated BSS entry is now followed properly and used
when the connection work starts.

7475d299ab P2P: Search all 2.4 GHz social channels regardless of disallow_freq
Commit 1595eb93ae ('P2P: Add support for
60 GHz social channel') had an unintended change to how P2P search scans
2.4 GHz social channels. Use of p2p_supported_freq() to filter the list
of social channels ended up using the disallow_freq setting to remove
social channels from the P2P search scans. This is not desired since
peers need to be found on any of the social channels even if those
channels have been disabled from P2P operating channel use. Restore the
previous behavior by included all the 2.4 GHz social channels in P2P
search scans if the driver indicated support for the 2.4 GHz band.

61fc90483f P2P: Handle improper WPS termination on GO during group formation
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
send WSC_Done). Such group formation attempt missed the event
notification about started group on the GO and also did not set the
internal state corresponding to the successful group formation.

This commit addresses the missing part by completing GO side group
formation on a successful first data connection if WPS does not complete
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.

pulling in both the main interface (e.g., wlan0) and P2P Device

the main interface ended up included both configuration files. This is
not really helpful for various use cases, e.g., when permanent P2P group
information is stored in the P2P Devince interface, but it gets
duplicated in the main station interface configuration.

Clean this up by changing the -m<file> argument to replace, not
concatenate, configuration information. In other words, the main station
interface will not read this configuration and the P2P Device interface
(non-netdev) does not read parameters from the station interface
configuration file.

6e252b0db3 WPS: Fix WPS-in-search check when STA_AUTOCONNECT is disabled
If "STA_AUTOCONNECT 0" has been used to disable automatic connection on
disconnection event and the driver indicates multiple disconnection
events for the disconnection from the current AP when WPS is started, it
could have been possible to hit a case where wpa_s->disconnected was set
to 1 during WPS processing and the following scan result processing
would stop the operation.

wpa_s->key_mgmt == WPA_KEY_MGMT_WPS check was trying to avoid to skip

c267753ba2 Add support for using random local MAC address
This adds experimental support for wpa_supplicant to assign random local
MAC addresses for both pre-association cases (scan, GAS/ANQP) and for
connections. MAC address policy for each part can be controlled
separately and the connection part can be set per network block.

This requires support from the driver to allow local MAC address to be
changed if random address policy is enabled. It should also be noted
that number of drivers would not support concurrent operations (e.g.,
P2P and station association) with random addresses in use for one or
both.

This functionality can be controlled with the global configuration
parameters mac_addr and preassoc_mac_addr which set the default MAC
address policies for connections and pre-association operations (scan
and GAS/ANQP while not connected). The global rand_addr_lifetime
parameter can be used to set the lifetime of a random MAC address in
seconds (default: 60 seconds). This is used to avoid unnecessarily
frequent MAC address changes since those are likely to result in driver
clearing most of its state. It should be noted that the random MAC
address does not expire during an ESS connection, i.e., this lifetime is
only for the case where the device is disconnected.

The mac_addr parameter can also be set in the network blocks to define
different behavior per network. For example, the global mac_addr=1 and
preassoc_mac_addr=1 settings and mac_addr=0 in a home network profile
would result in behavior where all scanning is performed using a random
MAC address while connections to new networks (e.g.,
Interworking/Hotspot 2.0) would use random address and connections to
the home network would use the permanent MAC address.

allow EAPOL-Start packet to be transmitted on startWhen reaching 0 even

b08d5fa793 WPS: Set EAPOL workarounds dynamically based on association

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
since WPS builds have likely received most testing for the past years
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
require the EAPOL-Start to initiate operation after a connection.

4e5367516b P2P: Overwrite pending interface only after verifying BSS entry
Previously, the P2P Interface Address of the peer gets updated in the
peer table every time based on the scan results.

For example, in a two port concurrency scenario, where the peer device
has two interfaces with unique P2P Interface Addresses and with same P2P
Device Address, based on the Probe Response/Beacon frames from these two
interfaces, their peer table gets updated, but each of these updates
happens in the peer table only based on the P2P Device Address. So, the
same peer's P2P Interface address is updated every time and hence, at
any instant, only one P2P Device Address to P2P Interface Address
mapping entry exist in the peer table for the peer which has two
interfaces.

When we try to join a group operated by the peer, lookup happens in the
peer table and when an interface entry is not available, the pending
interface address gets overwritten with the P2P Device Address and hence
the P2P connection can fail. Since the BSS table is the one that is
up-to-date, this fix will ensure that the interface overwriting will
happen only when there is no BSS entry for the pending P2P Interface
Address as well.

e3bd6e9dc0 P2P: Use another interface operating channel as listen channel
Performing a P2P Device flow such as p2p_listen or
p2p_find, can degrade the performance of an active interface
connection, if the listen frequency is different than the
frequency used by that interface.

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
externally, and will be delayed to a point where the P2P Device
state machine is idle.

The optimization can be configured in the configuration file and
is disabled by default.

a0c90bb073 P2P: Collect and use extended data on used frequencies
When the number of frequencies supported by the kernel is bigger than
one, and there is a need to pick a frequency for a new flow such as P2P
GO Negotiation or P2P Invitation, the flow should be able to pick the
best frequency among all the frequencies currently used by the device.

In order to prioritize between the currently used frequencies, add
the ability to collect additional data about each used frequency
(if the frequency is used by a station interface or P2P Client)
and when needed select the best frequency, where:

1. Infrastructure interfaces have highest priority
2. P2P Client interfaces have higher priority over AP/GO
   interfaces.

The rational is that the frequency of an AP/GO can change while
that of a station interface cannot.

d3b204694a P2P: Make the default p2p_find delay value configurable
This makes the p2p_find default delay value configurable as
p2p_search_delay parameter through the configuration file (and through
control interface "SET p2p_search_delay <value>" on the P2P management
interface.

This parameter controls the number milliseconds of extra delay that is
added between search iterations when there is a concurrent operation in
progress. This can be used, e.g., p2p_search_delay=100 to make p2p_find
friendlier to concurrent operations by avoiding it from taking 100% of
the radio resources. The default value is the previous default, i.e.,
500 ms. Smaller values can be used to find peers more quickly at the
cost of larger effect to concurrent operations while a larger value
leaves more time for the concurrent operations at the cost of making
device discovery take longer time.

The optional p2p_find delay argument can still be used to override the
search delay for each search operation.

Since the P2P_CONCURRENT_SEARCH_DELAY macro is not used anymore, the
driver specific build parameter for bcmdhd from Android.mk is also
removed. Similar configuration can now be achieved with
p2p_search_delay=0 in the p2p0 interface configuration file.

f0356ec85c eloop: Add epoll option for better performance
This patch adds epoll option for the eloop implementation. This can be
selected with the CONFIG_ELOOP_EPOLL=y build option.

[merit]
See Table1.

Table1. comparison table
+--------+--------+-----------+------------+-------------+
|        | add fd | remove fd | prepare fd | dispatch fd |
+--------+--------+-----------+------------+-------------+
| select | O(1)   | O(1)      | O(N)       | O(N)        |

+--------+--------+-----------+------------+-------------+
| epoll  | O(1)   | O(1)      | 0          | O(M)        |
+--------+--------+-----------+------------+-------------+
"add fd" is addition of fd by eloop_sock_table_add_sock().
"remove fd" is removal of fd by eloop_sock_table_remove_sock().
"prepare fd" is preparation of fds before wait in eloop_run().
"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
dispatchable fds. But epoll option doesn't require checking all registered fds.
Because epoll_wait() returns dispatchable fd set.

So epoll option is effective for GO/AP functionality.

[demerit]
The epoll option requires additional heap memory. In case of P2P GO, it is
about 8K bytes.

3e66f78914 P2P: Make sure GO start does not miss connect_without_scan
It looks like there was a possible sequence for wpa_s->scan_req to be
MANUAL_SCAN_REQ at the moment a GO is to be started. This could result
in the "Request scan (that will be skipped) to start GO" to actually not
skip the scan and end up stuck waiting for something external to trigger
a scan before the GO could be started. Fix this by clearing
wpa_s->scan_req when deciding to start the GO.

This issue could be hit at least by first enabling autoscan and then
issuing P2P_GROUP_ADD. Other sequences that set wpa_s->scan_req to
MANUAL_SCAN_REQ without going through wpa_supplicant_scan() to clear it
immediately could also have similar effect (and there is even a small
window for the wpa_supplicant_scan() call to happen only after the
P2P_GROUP_ADD command is processed, so this could potentially have
happened even with SCAN + P2P_GROUP_ADD).

d0df643735 wpa_supplicant: Call frequency conflict handling during auth
Previously, the frequency conflict was handled only during the
association flow. However, some drivers, e.g., mac80211 based
drivers, will fail an authentication request in case that there
are no available channels for use (as they might be used by
other interfaces), and thus the frequency conflict resolution
is never called.

Fix this by calling frequency conflict resolution during
authentication (SME-in-wpa_supplicant) as well.

In addition, get the shared radio frequency from the wpa_s context in
both the SME-in-driver and SME-in-wpa_supplicant cases and not from the
driver.

0cf24fdaed scan: Reset normal scan counter when a connection succeeds
The normal scan counter is used to trigger a few normal scans before a
scheduled scan is issued. The reason for doing this is that we get
results faster and some drivers support more SSIDs per normal scan
than during sched scan. After 2 normal scans, we start using
sched_scan. But the problem is that when a connection succeeds, we do
not reset this counter, so we will keep using sched scans.

To fix this, now we reset the counter when we switch to WPA_COMPLETED
state.

While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct the
VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the presence
of the respective IEs in the received TDLS Setup Response frame.

The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.

the P2P_DEVICE configuration parameters. If this option is not used, the

Note that it is advised to use this option in some cases such as:

If a P2P_DEVICE is supported by the driver, the wpa_supplicant creates a
dedicated P2P Device interface, where the configuration file used for
the main interface is used. As a consequence, if the configuration file
includes network definition etc., the wpa_supplicant will try to perform
station specific flows on the P2P Device interface which will fail.

If a P2P_DEVICE is supported by the driver and update_config is used,
the P2P Device configuration data will override the main interface
configuration data.

This optimization option should be used if the driver supports stations

For example, the optimization option will always be used for cfg80211

The special case of non-zero status code used in a GAS Comeback Response
frame to indicate that additional delay is needed before the response is
available was not working properly. This case needs to allow the status
code check to be bypassed for the comeback case prior to having received
any response data.

Commits 7ef6947993 and
533536d82a added this temporarily
disabling case, but those commits were merged in without having been
converted to the new os_reltime design used for ssid->disabled_until.
Consequently, they ended up disabling the network for 44 years or so too
long time (depending on what values the relative timestamp had
accummulated so far). Fix this by using relative timestamps
consistently.

b7fb98f072 Interworking: Fix already-connected check to verify network priority
Commit d28f4e44f1 optimized Interworking
network selection in a case where the operation is run while already
connected to the selected network by skipping the reconnection. However,
this did not take into account that a higher priority network may have
shown up in the new scan results.

Fix this by checking whether network selection based on the latest scan
results (the ones from the interworking_select operation) would result
in a network with higher priority being selected. If so, skip the
optimization and force normal network connection (which will select this
newly found higher priority network). This fixes cases where a
non-Hotspot 2.0 network with higher priority (e.g., home network) shows
up while connected to a Hotspot 2.0 network with lower priority.

network selection preferences. However, it did not take into account
that other network block may have higher priority. In such cases, the
last added network from Interworking network selection should actually
not be selected for the next connection. Fix this by limiting the
last-network preference to work only within a priority class.

Some times it is seen that before advancing to next device in the list,

bab6677a31 Handle Wi-Fi Display commands more carefully if P2P is disabled
If P2P was disabled (e.g., due to driver not supporting it or through
p2p_disabled=1 configuration), setting Wi-Fi Display parameters could
result in segmentation fault when the WFD IE is updated without the P2P
module being initialized. Fix this by skipping the update if P2P module
is not in use. In addition, show Wi-Fi Display as disabled in "GET
wifi_display" and refuse to enable it with "SET wifi_display 1" if P2P
is not enabled.

94ff22ea08 Remove dead code from AP setup
wpa_supplicant_create_ap() is only called for AP mode, so there is no
point in trying to address station (infra/IBSS) modes.

0b5ff2ae12 WPS: Remove unused Credential AP Channel processing
Commit bd3a373767 added a mechanism to use
AP Channel attribute from within a Credential attribute to optimize
scans. However, this design is not actually used with the WPS NFC use
cases. With configuration token, the AP Channel attribute is in the same
container with the Credential attribute (and that was also handled in
the previous implementation). With connection handover, AP Channel
information is outside the Credential attribute as well.

Simplify implementation by removing the AP Channel within Credential
case. This allows wpas_wps_use_cred() to get the AP Channel from the
container instead of having to find this during credential iteration.

d950477913 Fix authentication algorithm negotiation in SME code
Commit 6ac4b15ef8 (wpa_radio work for
connection) caused a regression for cases where multiple auth_alg values
are set in a network block and wpa_supplicant-based SME is supposed to
iterate through them. The connection radio work was not terminated when
receiving authentication failure and this resulted in the following
authentication attempt failing.

04c366cb1d Fix memory leaks and wrong memory access
1. In wpa_config_process_bgscan() fix memory leak after
   calling wpa_config_parse_string()
2. In hostapd_config_defaults(), on failure to allocate bss->radius,
   conf->bss was not freed.
3. In p2p_deauth_nofif(), memory allocated in p2p_parse_ies() was not
   freed in case of NULL minor_reason_code.
4. In p2p_disassoc_nofif(), memory allocated in p2p_parse_ies() was
   not freed in case of NULL minor_reason_code.
5. In p2p_process_go_neg_conf(), memory allocated was not freed in
   case that the P2P Device interface was not waiting for a
   GO Negotiation Confirm.
6. In wpa_set_pkcs11_engine_and_module_path(), the wrong pointer was
   checked.
