Import hostapd 0.7.3.

Changes:

2010-09-07 - v0.7.3

• fixed re-association after WPS not initializing WPA state machine in

	  some cases

• fixed WPS IE update on reconfiguration
• fixed WPS code not to proxy Probe Request frames for foreign SSIDs
• added WPS workaround for open networks and some known interop issues
• fixed WPS Diffie-Hellman derivation to use correct public key length
• fixed FT RRB messages on big endian CPUs
• changed WPS protection for brute force AP PIN attacks to disable AP

	  PIN only temporarily (but with increasing time) to avoid usability
	  issues on Label-only devices

• added wps_ap_pin command for more secure handling of AP PIN

	  operations (e.g., to generate a random AP PIN and only use it for
	  short amount of time)

• fixed HT STBC negotiation

2010-04-18 - v0.7.2

• fix WPS internal Registrar use when an external Registrar is also

	  active

• bsd: Cleaned up driver wrapper and added various low-level

	  configuration options

• TNC: fixed issues with fragmentation
• EAP-TNC: add Flags field into fragment acknowledgement (needed to

	  interoperate with other implementations; may potentially breaks
	  compatibility with older wpa_supplicant/hostapd versions)

• cleaned up driver wrapper API for multi-BSS operations
• nl80211: fix multi-BSS and VLAN operations
• fix number of issues with IEEE 802.11r/FT; this version is not

	  backwards compatible with old versions

• add SA Query Request processing in AP mode (IEEE 802.11w)
• fix IGTK PN in group rekeying (IEEE 802.11w)
• fix WPS PBC session overlap detection to use correct attribute
• hostapd_notif_Assoc() can now be called with all IEs to simplify

	  driver wrappers

• work around interoperability issue with some WPS External Registrar

	  implementations

• nl80211: fix WPS IE update
• hostapd_cli: add support for action script operations (run a script

	  on hostapd events)

• fix DH padding with internal crypto code (mainly, for WPS)
• fix WPS association with both WPS IE and WPA/RSN IE present with

	  driver wrappers that use hostapd MLME (e.g., nl80211)

2010-01-16 - v0.7.1

• cleaned up driver wrapper API (struct wpa_driver_ops); the new API

	  is not fully backwards compatible, so out-of-tree driver wrappers
	  will need modifications

• cleaned up various module interfaces
• merge hostapd and wpa_supplicant developers' documentation into a

	  single document

• fixed HT Capabilities IE with nl80211 drivers
• moved generic AP functionality code into src/ap
• WPS: handle Selected Registrar as union of info from all Registrars
• remove obsolte Prism54.org driver wrapper
• added internal debugging mechanism with backtrace support and memory

	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)

• EAP-FAST server: piggyback Phase 2 start with the end of Phase 1
• WPS: add support for dynamically selecting whether to provision the

	  PSK as an ASCII passphrase or PSK

• added support for WDS (4-address frame) mode with per-station virtual

	  interfaces (wds_sta=1 in config file; only supported with
	  driver=nl80211 for now)

• fixed WPS Probe Request processing to handle missing required

	  attribute

• fixed PKCS#12 use with OpenSSL 1.0.0
• detect bridge interface automatically so that bridge parameter in

	  hostapd.conf becomes optional (though, it may now be used to
	  automatically add then WLAN interface into a bridge with
	  driver=nl80211)

2009-11-21 - v0.7.0

• increased hostapd_cli ping interval to 5 seconds and made this

	  configurable with a new command line options (-G<seconds>)

• driver_nl80211: use Linux socket filter to improve performance
• added support for external Registrars with WPS (UPnP transport)
• 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
• driver_nl80211: fixed STA accounting data collection (TX/RX bytes

	  reported correctly; TX/RX packets not yet available from kernel)

• added support for WPS USBA out-of-band mechanism with USB Flash

	  Drives (UFD) (CONFIG_WPS_UFD=y)

• fixed EAPOL/EAP reauthentication when using an external RADIUS

	  authentication server

• fixed TNC with EAP-TTLS
• fixed IEEE 802.11r key derivation function to match with the standard

	  (note: this breaks interoperability with previous version) [Bug 303]

• fixed SHA-256 based key derivation function to match with the

	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
	  (note: this breaks interoperability with previous version) [Bug 307]

• added number of code size optimizations to remove unnecessary

	  functionality from the program binary based on build configuration
	  (part of this automatic; part configurable with CONFIG_NO_* build
	  options)

• use shared driver wrapper files with wpa_supplicant
• driver_nl80211: multiple updates to provide support for new Linux

	  nl80211/mac80211 functionality

• updated management frame protection to use IEEE Std 802.11w-2009
• fixed number of small WPS issues and added workarounds to

	  interoperate with common deployed broken implementations

• added some IEEE 802.11n co-existance rules to disable 40 MHz channels

	  or modify primary/secondary channels if needed based on neighboring
	  networks

• added support for NFC out-of-band mechanism with WPS
• added preliminary support for IEEE 802.11r RIC processing
