3302b7c29f Rate limit SA Query procedure initiation on unprotected disconnect
There is no need to trigger new SA Query procedure to check the state of
the connection immediately after having performed such a check. Limit
the impact of burst of unprotected Deauth/Disassoc frames by starting a
new SA Query procedure only once at least 10 seconds has passed from the
previous SA Query that was triggered by reception of an unprotected
disconnection. The first SA Query procedure for each association does
not follow this rule to avoid issues with test cases that expect to see
an SA Query every time.

947f900fb8 TDLS: Handle unreachable link teardown for external setup
If a link is unreachable, the specification mandates we should send a
teardown packet via the AP with a specific teardown reason. Force this
by first disabling the link and only then sending the teardown packet
for the LOW_ACK event.

Rename the TDLS LOW_ACK event handler to better reflect its purpose.

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.

Commit b125c48fce ('P2P: Add wfd_dev_info=
field for device found event') added Wi-Fi Display device info to the
P2P-DEVICE-FOUND events. However, it did not include proper bounds
checking in wifi_display_subelem_hex() and could accept subelements with
invalid length field values. This could result in buffer read overflow
of up to 64 kB and inclusion of heap memory in the local control
interface event and/or process crash due to invalid memory access. Fix
this by checking the validity of the length field before writing a
hexdump of the data.

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.

b77aeae732 Interworking: Re-trigger scan if no connect attempt is done
For one specific case when running with Interworking enabled the

The case is:
- Interworking credentials available, but do not match
- Auto interworking is enabled (auto_interworking=1)
- Interworking auto select is disabled (i.e., this is from
  auto_interworking=1, not from INTERWORKING_SELECT auto)
- No configured (enabled and non blacklisted) networks are present
  in scan results list with full match
- Interworking finds matching networks (it does not do full security
  policy match)

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.

See Table1.

|        | 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.

This could have left P2P module in invalid state if the interface got
disabled during a p2p_find or p2p_listen operation. Clear the state in
such a case to avoid blocking following operations due to P2P module
assuming it is still in progress of doing something.

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.

96ecea5eb1 Pass TDLS peer capability information in tdls_mgmt
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.

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.

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

7c373ac267 Interworking: Fix last-network preference to not override priority
Commit 3d910ef497 tried to make
last-network selection behave more consistently with Interworking
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.

case.

Some times it is seen that before advancing to next device in the list,
the scan results come and update SD_SCHEDULE flag. This will result in

to other devices. This issue again is seen with peer devices advertising
SD capability without any services registered.

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.

Fix memory allocation in wpa_scan_clone_params(), where the
allocation request used the size of a pointer rather than the
size of the structure.

c209dd1108 WPS NFC: nfcpy script to use new connection handover design
Fetch a carrier record from wpa_supplicant instead of full handover
request. This makes it easier for external programs to build handover
request messages with multiple alternative carriers.
