The previous elements need to be moved only if we are inserting the new
network in the middle of the list. While the memmove of zero bytes at
the end of the array does not cause real problems, some static analyzers
complain about this, so in addition to slightly optimized
implementation, this removes some analyzer warnings, too.

This allows credentials to be set with a specific priority to allow
the automatic network selection behavior to be controlled with user
preferences. The priority values are configured to the network block
and BSS selection will select the network based on priorities from
both pre-configured network blocks and credentials.

New wpa_cli commands list_creds, add_cred, remove_cred, and set_cred

This replaces the global home_* parameters with a list of credentials
that can be configured similarly to network blocks. For example:

This allows HT capabilities overrides on kernels that
support these features.
MCS Rates can be disabled to force to slower speeds when using HT.
Rates cannot be forced higher.
HT can be disabled, forcing an 802.11a/b/g/n station to act like
an 802.11a/b/g station.
HT40 can be disabled.
MAX A-MSDU can be disabled.
A-MPDU Factor and A-MPDU Density can be modified.
Please note that these are suggestions to the kernel. Only mac80211
drivers will work at all. The A-MPDU Factor can only be decreased and
the A-MPDU Density can only be increased currently.

Add a new persistent group network block field, p2p_client_list, to
maintain a list of P2P Clients that have connected to a persistent
group. This allows GO of a persistent group to figure out more easily
whether re-invocation of a persistent group can be used with a specific
peer device.

New configuration parameters home_imsi and home_milenage can be used
to configure SIM/USIM simulator parameters for network selection based
on SIM/USIM credentials.
home_imsi=(MCC | MNC | '-' | rest of IMSI)
home_milenage=(Ki):(OPc):(SQN)
For example:
home_imsi=310026-000000000
home_milenage=90dca4eda45b53cf0f12d7c9c3bc6a89:cb9cccc4b9258e6dca4760379fb82581:000000000123
Add support for network selection for username/password credentials with
EAP-TTLS and EAP-PEAP. The new global configuration parameters
home_username, home_password, and home_ca_cert can be used to specify
credentials for network selection.
The new wpa_supplicant.conf file global parameters interworking and
hessid can be used to configure wpa_supplicant to include
Interworking element in Probe Request frames.
Replace compile-time BSS cache expiration age and scan count by config
parameters that can be set via wpa_cli and the new D-Bus API. The latter
is done with interface properties BSSExpireAge and BSSExpireCount.
This adds a new command to the interface to remove all configured
netblocks. Without this it's necessary to query properties on the
interface and explicitly remove each netblock.
Instead of converting back and forth from the string representation,
always use the binary representation internally.

When the network was provisioned, we need to get the keys to be able to
reconnect without new provisioning. To be able to publish those keys but
not normally configured ones, add a new attribute to struct wpa_ssid
indicating whether or not keys may be exported.

The nl80211 driver can report low ACK condition (in fact it reports
complete loss right now only). Use that, along with a config option, to
disconnect stations when the data connection is not working properly,
e.g., due to the STA having went outside the range of the AP. This is
disabled by default and can be enabled with disassoc_low_ack=1 in
hostapd or wpa_supplicant configuration file.

A new configuration parameter, p2p_group_idle, can now be used to set
idle timeout value for P2P groups in seconds (0 = no timeout). If set,
this values is used to remove P2P group (both GO and P2P client)
interfaces after the group has been idle (no clients/GO seen) for the
configuration duration.
The P2P-GROUP-REMOVED event is now indicating the reason for group
removal when known. For example:
P2P-GROUP-REMOVED wlan0 GO reason=REQUESTED
P2P-GROUP-REMOVED wlan1 client reason=IDLE
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.
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.

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.
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.
The following defines are not really needed in most places, so
remove them to clean up source code and build scripts:
EAP_TLS_FUNCS
EAP_TLS_OPENSSL
EAP_TLS_GNUTLS
CONFIG_TLS_INTERNAL
In addition, start ordering header file includes to be in more
consistent order: system header files, src/utils, src/*, same
directory as the *.c file.
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.
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
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.

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.
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.
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.
Setting the value of the SET_NETWORK command to NULL (without quotation)
unsets the variable, i.e., removes it from configuration file. This is
needed to allow GUI programs to clear variables, e.g., identity for
EAP-AKA/SIM.
IEEE 802.11w/D6.0 defines new AKMPs to indicate SHA256-based algorithms for
key derivation (and AES-CMAC for EAPOL-Key MIC). Add support for using new
AKMPs and clean up AKMP processing with helper functions in defs.h.
