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.

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.

03ed332407 Interworking: Allow cred blocks not to be saved to a file
The new cred block parameter 'temporary' can be used to indicate that a
cred block is not to be saved to wpa_supplicant configuration file
(e.g., "SET_CRED 0 temporary 1"). This is similar to the concept of
temporary network blocks and allows cred blocks to be managed outside
the wpa_supplicant config file when other parameters are still saved to
the file written by wpa_supplicant.

800d58721c TDLS: Provide external control to specify the peers for setup
There are use cases requesting the host driver to initiate the TDLS
setup with the peer only when configured by the external applications.
Thus, enable this control by tdls_external_control=1 and pass the
requisite information for the specific TDLS operation to the driver
on the request from such use cases.

This operation mode expects the driver to initiate TDLS link
automatically based on signal strength and traffic to a peer and tear
down links whenever they are not used or suitable due to signal strength
etc. The list of peers with which such operations are to be performed
are provided with the TDLS driver operations.

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.

ea61aa1de1 Add no_ctrl_interface config param to clear ctrl_interface
This can be used to override previously set ctrl_interface value in a
way that clears the variable to NULL instead of empty string. The only
real use case for this is to disable per-interface ctrl_interface from
the additional control file (-I<file>) in case ctrl_interface was set in
the main configuration file. It should be noted that zero-length
ctrl_interface parameter can be used to initiate some control interface
backends, so simpler designs were not available for this.

The format of the new parameter is not exactly cleanest due to
configuration file parsing assumptions. For example:

ctrl_interface=....
no_ctrl_interface=

would end up with ctrl_interface=NULL.

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).

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.

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.

part of the normal (non-Interworking) network selection if the scan
results do not match with enabled networks. This makes scanning work
similarly to the "interworking_select auto" command.

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
experience.

b766a9a293 Add freq_list network configuration parameter
This can be used to limit which frequencies are considered when
selecting a BSS. This is somewhat similar to scan_freq, but will
also affect any scan results regardless of which program triggered
the scan.

aa53509ffe Update priority list after priority change
Despite comments in the wpa_config_update_prio_list(struct wpa_config
*config) telling that it is called "if priority for a network is
changed", it is apparently not.

c9c38b0996 Make maximum BSS table size configurable
New global configuration parameter bss_max_count can now be used to
change the maximum BSS table size. The old fixed size limit (200) is
used as the default value for this parameter.

c0e4dd9eeb WPS: Make Config Methods configurable for wpa_supplicant
This adds config_methods configuration option for wpa_supplicant
following the design used in hostapd. In addition, the string is
now parsed in common code from src/wps/wps_common.c and the list
of configurable methods include all the defined methods from
WPS 1.0h spec.

60b94c9819 Add preliminary background scan and roaming module design
This allows background scanning and roaming decisions to be contained in
a single place based on a defined set of notification events which will
hopefully make it easier to experiment with roaming improvements. In
addition, this allows multiple intra-ESS roaming policies to be used
(each network configuration block can configure its own bgscan module).

The beacon loss and signal strength notifications are implemented for
the bgscan API, but the actual events are not yet available from the
driver.

The included sample bgscan module ("simple") is an example of what can
be done with the new bgscan mechanism. It requests periodic background
scans when the device remains associated with an ESS and has couple of
notes on what a more advanced bgscan module could do to optimize
background scanning and roaming. The periodic scans will cause the scan
result handler to pick a better AP if one becomes available. This bgscan
module can be taken into use by adding bgscan="simple" (or
bgscan="simple:<bgscan interval in seconds>") into the network
configuration block.

d3a9822542 Add support for specifying subset of enabled frequencies to scan
A new network block parameter, scan_freq, can be used to specify subset
of frequencies to scan. This can speed up scanning process considerably
if it is known that only a small subset of channels is actually used in
the network. A union of configured frequencies for all enabled network
blocks is used in scan requests.

Currently, only driver_nl80211.c has support for this functionality.

For example, following parameter marks 2.4 GHz channels 1, 6, 11 to be
scanned: scan_freq=2412 2437 2462

1581b38b67 Initial step in adding simple AP mode support into wpa_supplicant
This version is adding the configuration option (mode=2) for this and
driver capability reporting to figure out whether AP mode can be used.
However, this does not actually implement any real functionality yet.

ad08c3633c Added preliminary Wi-Fi Protected Setup (WPS) implementation
This adds WPS support for both hostapd and wpa_supplicant. Both programs
can be configured to act as WPS Enrollee and Registrar. Both PBC and PIN
methods are supported.

Currently, hostapd has more complete configuration option for WPS
parameters and wpa_supplicant configuration style will likely change in
the future. External Registrars are not yet supported in hostapd or
wpa_supplicant. While wpa_supplicant has initial support for acting as
an Registrar to configure an AP, this is still using number of hardcoded
parameters which will need to be made configurable for proper operation.

98842d51ec Separate OpenSSL engine configuration for Phase 2
I fixed the engine issue in phase2 of EAP-TTLS. The problem was that you
only defined one engine variable, which was read already in phase1. I
defined some new variables:

engine2
engine2_id
pin2

and added support to read those in phase2 wheres all the engine
variables without number are only read in phase1. That solved it and I
am now able to use an engine also in EAP-TTLS phase2.

581a8cde77 Added support for enforcing frequent PTK rekeying
Added a new configuration option, wpa_ptk_rekey, that can be used to
enforce frequent PTK rekeying, e.g., to mitigate some attacks against TKIP
deficiencies. This can be set either by the Authenticator (to initiate
periodic 4-way handshake to rekey PTK) or by the Supplicant (to request
Authenticator to rekey PTK).

With both wpa_ptk_rekey and wpa_group_rekey (in hostapd) set to 600, TKIP
keys will not be used for more than 10 minutes which may make some attacks
against TKIP more difficult to implement.
