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).

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

connection, but reallocated BSS entry is now followed properly and used

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.

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.

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.

now be used to specify a list of network ids that have scan_ssid=1 to
indicate active scanning of the SSID. This adds the listed SSIDs to the
scan command to allow manual scan requests to perform active scans for
hidden SSIDs. For example, "SCAN scan_id=1,7,11" would run a scan with
the SSID fetched from the configured network blocks 1, 7, and 11
(assuming those are set with scan_ssid=1). The SSIDs will be included
even from network blocks that are currently disabled.
The maximum number of SSIDs added to the request is limited by the
driver support. If more than supported values are specified, the command
will fail (returns "FAIL").

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.

When the number of frequencies supported by the kernel is bigger than

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.

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.

"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.

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

Using binutils >= 2.24.x and setting
CONFIG_WPA_TRACE/CONFIG_WPA_TRACE_BDF causes both builds to fail with
"#error config.h must be included before this header" message.
Since version 2.24.x, the bfd header checks for PACKAGE and
PACKAGE_VERSION macros.
As suggested in http://sourceware.org/bugzilla/show_bug.cgi?id=14243
projects that use bfd and don't use autotools should define a PACKAGE
macro.

Since P2P specification mandates P2P GO to support WMM-PS with legacy
STAs, enable this automatically if the driver indicates support for
U-APSD in AP mode. The "P2P_SET go_apsd 0" command can still be used to
disable this if needed.

While testing rfkill blocking of a scanning interface, it
was seen that the ongoing scan never completes. This happens
since EVENT_SCAN_RESULTS is discarded on a disabled interface.
Fix this and also other possible radio work completion issues
by removing all the radio works (including started) of the
disabled interface.
To be able to remove already started radio works, make their
callbacks be reentrant with deinit flag (when the work
is started), so each radio work should be able to handle
its own termination.

The current nfcpy version does not support new WSC connection handover
message format and the handover server fails to process the request due
to a debug print. As a temporary workaround, override
HandoverServer::_process_request() with a version that avoids pretty()
print of the handover messages. This can be removed once nfcpy has been
updated to support the new format.

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

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.
