19c48da06b Clear wpa_supplicant configuration keys explicitly
Use an explicit memset call to clear any wpa_supplicant configuration
parameter that contains private information like keys or identity. This
brings in an additional layer of protection by reducing the length of
time this type of private data is kept in memory.

a1e46f320d Check for no key_mgmt/proto/auth_alg entries in config writer
This is not really necessary check, but it keeps a static analyzer
happier by avoiding dead increment. Doing it this way rather than
removing the increment is less likely to cause problems when new entries
are added here in the future (the "dead" increment would be very much
needed in those cases).

1b928f96b6 P2P: Allow passphrase length to be configured
Previously, eight character random passphrase was generated
automatically for P2P GO. The new p2p_passphrase_len parameter can be
used to increase this length to generate a stronger passphrase for cases
where practicality of manual configuration of legacy devices is not a

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.

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.

25ef8529c1 P2P: Add support for IP address assignment in 4-way handshake
This new mechanism allows P2P Client to request an IPv4 address from the
GO as part of the 4-way handshake to avoid use of DHCP exchange after
4-way handshake. If the new mechanism is used, the assigned IP address
is shown in the P2P-GROUP-STARTED event on the client side with
following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP
address is included in the AP-STA-CONNECTED event on the GO side as a
new ip_addr parameter. The IP address is valid for the duration of the
association.

The IP address pool for this new mechanism is configured as global
wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask,
ip_addr_star, ip_addr_end. For example:

ip_addr_go=192.168.42.1
ip_addr_mask=255.255.255.0
ip_addr_start=192.168.42.2
ip_addr_end=192.168.42.100

DHCP mechanism is expected to be enabled at the same time to support P2P
Devices that do not use the new mechanism. The easiest way of managing
the IP addresses is by splitting the IP address range into two parts and
assign a separate range for wpa_supplicant and DHCP server.

5079392954 Increase buffer size and prevent write beyond buffer end
wpa_config_write_key_mgmt has a buffer size of 50. This is not enough
to fit the longest case. I used a network with "WPA-PSK WPA-EAP
WPA-NONE" and CONFIG_IEEE80211R=y + CONFIG_IEEE80211W=y to produce
a string longer than 50 chars. Increase the buffer size to 100 to
prevent truncated output.

Truncated output is not the only problem. If the buffer end is
reached when adding certain key mgmt types the function does not
return immediately. This leaves pos > end. When a second os_sprintf
is called the calculation of end - pos yields a large positive
number for buffer size. End result is a write beyond the buffer end.
Fix this by bailing out if buffer end is reached.

The format of the new parameter is not exactly cleanest due to

080585c01a Add support for OCSP stapling to validate server certificate
When using OpenSSL with TLS-based EAP methods, wpa_supplicant can now be
configured to use OCSP stapling (TLS certificate status request) with
ocsp=1 network block parameter. ocsp=2 can be used to require valid OCSP
response before connection is allowed to continue.

hostapd as EAP server can be configured to return cached OCSP response
using the new ocsp_stapling_response parameter and an external mechanism
for updating the response data (e.g., "openssl ocsp ..." command).

This allows wpa_supplicant to verify that the server certificate has not
been revoked as part of the EAP-TLS/PEAP/TTLS/FAST handshake before
actual data connection has been established (i.e., when a CRL could not
be fetched even if a distribution point were specified).

b277a2bebc P2P: Allow shared interface channel preference to be ignored
p2p_ignore_shared_freq=1 in the configuration file (or "SET
p2p_ignore_shared_freq 1" on control interface) can now be used to
configure wpa_supplicant to ignore the preference on shared operating
channel when the driver support multi-channel concurrency. The default
behavior is to try to start any new P2P group on an operating channel
that is already in use on another virtual interface to avoid extra cost
from hopping between multiple channels. If this new parameter is set to
1, such preference is not used and instead, the channel for the new P2P
group is selected based on other preferences while ignoring operating
channels of any concurrent connection.

By default, P2P is enabled globally for all virtual interfaces and this

all scans even if this is for a non-P2P station connection to speed up
device discovery. If an interface is dedicated for non-P2P station mode
operations, it is now possible to disable addition of WSC and P2P IEs
into Probe Request frames with a per-interface p2p_disabled parameter.
This can be set either in the configuration file (p2p_disabled=1) or at
run time ("wpa_cli -i wlan0 set p2p_disabled 1"). Unlike the previous
mechanism ("wpa_cli p2p_set disabled 1"), the new parameter changes the
behavior only for the specified interface while other interfaces
continue to follow the global P2P enabled/disabled state.

462a7439e1 Add p2p_go_max_inactivity config option
This enables setting a different max inactivity timeout for P2P GO.
This timeout is used to detect inactive clients. In some scenarios
it may be useful to have control over this and set a shorter timeout
than the default 300s. For example when running STA and P2P GO interfaces
concurrently, the STA interface may perform scans which may cause the
GO to miss a disassoc / deauth frames from a client and keep assuming
that the client is connected until the inactivity detection kicks in.
300 secs is a bit too long for such scenarios and creates a bad user
