0629eeb490 RRM: Add AP mode minimal advertisement support for testing
The new hostapd.conf radio_measurements parameter can now be used to
configure a test build to advertise support for radio measurements with
neighbor report enabled. There is no real functionality that would
actually process the request, i.e., this only for the purpose of minimal
STA side testing for now.

d3bddd8b84 ERP: Add support for ERP on EAP server and authenticator
Derive rRK and rIK on EAP server if ERP is enabled and use these keys to

The new hostapd configuration parameter eap_server_erp=1 can now be used

the successful completion of an EAP authentication method. This
functionality is not included in the default build and can be enabled

7d597d4617 AP: Add support for Proxy ARP, DHCP snooping mechanism
Proxy ARP allows the AP devices to keep track of the hardware address to
IP address mapping of the STA devices within the BSS. When a request for
such information is made (i.e., ARP request, Neighbor Solicitation), the
AP will respond on behalf of the STA device within the BSS. Such
requests could originate from a device within the BSS or also from the
bridge. In the process of the AP replying to the request (i.e., ARP
reply, Neighbor Advertisement), the AP will drop the original request
frame. The relevant STA will not even know that such information was
ever requested.

This feature is a requirement for Hotspot 2.0, and is defined in IEEE
Std 802.11-2012, 10.23.13. While the Proxy ARP support code mainly
resides in the kernel bridge code, in order to optimize the performance
and simplify kernel implementation, the DHCP snooping code was added to
the hostapd.

ec8f36afca AP: Add support for BSS load element (STA Count, Channel Utilization)
The new "bss_load_update_period" parameter can be used to configure
hostapd to advertise its BSS Load element in Beacon and Probe Response
frames. This parameter is in the units of BUs (Beacon Units).

When enabled, the STA Count and the Channel Utilization value will be
updated periodically in the BSS Load element. The AAC is set to 0 sinze
explicit admission control is not supported. Channel Utilization is
calculated based on the channel survey information from the driver and
as such, requires a driver that supports providing that information for
the current operating channel.

599f40db7d Remove extra indentation level from hostapd_config_fill()
The configuration file parsing routines were moved to a separate
function a while back, but left at the old indentation level to avoid
showing large diffs in the commit and to avoid conflicts with parallel
development in other branches. There is never a perfect time for this
type of changes, but we might as well finally get rid of that extra
indentation now with Hotspot 2.0 Rel 2 changes pulled in.

70ee1be248 hostapd: Add config option chanlist for DFS channels
Different channels allow different transmission power, at least in ETSI

channels should be randomly choosen from these channels.

Add a channel list configuration option for users to add channels

09eef142ea Use internal FIPS 186-2 PRF if needed
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.

354c903f8e AP/GO interface teardown optimization
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).
