Commit 86bd36f0d5 ("Add generic

where it miscalculates the length of memory to move using

lead to out of bounds memory accesses.
This patch fixes this by calculating the correct length of remaining

Previously, the case of non-netdev P2P management device ended up
pulling in both the main interface (e.g., wlan0) and P2P Device
interface (from command line -m argument) as configuration. Similarly,
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.

If "STA_AUTOCONNECT 0" has been used to disable automatic connection on

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.

An interoperability issue with a deployed AP has been identified where
the connection fails due to that AP failing to operate correctly if
PMKID is included in the Association Request frame. To work around this,
allow EAPOL-Start packet to be transmitted on startWhen reaching 0 even
when trying to use PMKSA caching. In practice, this allows fallback to
full EAP authentication if the AP/Authenticator takes more than 1-2
seconds to initiate 4-way handshake for PMKSA caching or full EAP

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
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

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.

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.

- Auto interworking is enabled (auto_interworking=1)
- Interworking auto select is disabled (i.e., this is from

- No configured (enabled and non blacklisted) networks are present

"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.

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

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

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

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.

This commit adds an option to optimize AP teardown by leaving the
deletion of keys (including group keys) and stations to the driver.
This optimization option should be used if the driver supports stations
and keys removal when stopping an AP.
For example, the optimization option will always be used for cfg80211
drivers since cfg80211 shall always remove stations and keys when
stopping an AP (in order to support cases where the AP is disabled
without the knowledge of wpa_supplicant/hostapd).

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.

Suppose we have multiple peers and we have peers advertising SD
capability, but no services registered for advertising. In this case,

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