Remove the seperation between getting the local interface frequency and

Signed-off-by: Avraham Stern <avraham.stern@intel.com>
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=

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.

"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.

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

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

If a new connection is attempted while there is a pending sme-connection
radio work, cancel the pending radio work and continue with the new
connection attempt. This is preferable over rejecting the new work and
continuing with the pending one, as it is possible that the previous
work is no longer valid.

According to the standard, if the max A-MPDU VHT cap is <= 3, we
have to adjust the max A-MPDU HT cap to the same value. Otherwise
it should be set to 3.
Take care of it when the max VHT A-MPDU value is overridden.

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 40 MHz intolerant bit needs to be checked before skipping the BSS
based on the channel already being in the lost (which could have
happened due to another BSS that does not indicate 40 MHz intolerant).
This fixed the 20/40 MHz co-ex report to indicate 20 MHz request
properly if there are both 40 MHz tolerant and intolerant BSSes on the
same channel.

The radio_work type was stored within the dynamically allocated
wpa_radio_work buffer and that buffer ended up getting freed before the

Add "reattach" command to perform single-channel single-ssid scan
instead of full scan when trying to reconnect to the currently
"connected" network (assuming old scan results are not current enough to
skip the scan completely). This allows the scan result to come back in
much faster time. In ath9k, the scan took around 12 seconds with full
background scan, and only 0.1 second with the single-channel single-ssid
scan. Thus, take much less time for the client to re-establish
connection with the currently "connected" network.

Previously, EAP-SIM/AKA/AKA' did not work with number of crypto
libraries (GnuTLS, CryptoAPI, NSS) since the required FIPS 186-2 PRF
function was not implemented. This resulted in somewhat confusing error
messages since the placeholder functions were silently returning an
error. Fix this by using the internal implementation of FIP 186-2 PRF
(including internal SHA-1 implementation) with crypto libraries that do
not implement this in case EAP-SIM/AKA/AKA' is included in the build.

This enables more convenient protocol testing of AP and P2P
functionality in various error cases and unexpected sequences without
having to implement each test scenario within wpa_supplicant.
ext_mgmt_frame_handle parameter can be set to 1 to move all management
frame processing into an external program through control interface
events (MGMT-RX and MGMT-TX-STATUS) and command (MGMT_TX). This is
similar to the test interface that was added to hostapd previously, but
allows more control on offchannel operations and more direct integration
with the internal P2P module.

Add an option to specify a configuration file that can be used to hold
the P2P_DEVICE configuration parameters. If this option is not used, the
P2P_DEVICE configuration parameters will be read from interface
configuration file.
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.
