See hostapd.conf. * Add support for IEEE 802.11v Time Advertisement mechanism with UTC TSF offset. See hostapd.conf for config info. * Delay STA entry removal until Deauth/Disassoc TX status in AP mode. This allows the driver to use PS buffering of Deauthentication and Disassociation frames when the STA is in power save sleep. Only available with drivers that provide TX status events for Deauth/ Disassoc frames (nl80211). * Allow PMKSA caching to be disabled on the Authenticator. See hostap.conf config parameter disable_pmksa_caching. * atheros: Add support for IEEE 802.11w configuration. * bsd: Add support for setting HT values in IFM_MMASK. * Allow client isolation to be configured with ap_isolate. Client isolation can be used to prevent low-level bridging of frames between associated stations in the BSS. By default, this bridging is allowed. * Allow coexistance of HT BSSes with WEP/TKIP BSSes. * Add require_ht config parameter, which can be used to configure hostapd to reject association with any station that does not support HT PHY. * Add support for writing debug log to a file using "-f" option. Also add relog CLI command to re-open the log file. * Add bridge handling for WDS STA interfaces. By default they are added to the configured bridge of the AP interface (if present), but the user can also specify a separate bridge using cli command wds_bridge. * hostapd_cli: - Add wds_bridge command for specifying bridge for WDS STA interfaces. - Add relog command for reopening log file. - Send AP-STA-DISCONNECTED event when an AP disconnects a station due to inactivity. - Add wps_config ctrl_interface command for configuring AP. This command can be used to configure the AP using the internal WPS registrar. It works in the same way as new AP settings received from an ER. - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. - Add command get version, that returns hostapd version string. * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. Use hostapd_cli ess_disassoc (STA addr) (URL) to send the notification to the STA. * Allow AP mode to disconnect STAs based on low ACK condition (when the data connection is not working properly, e.g., due to the STA going outside the range of the AP). Disabled by default, enable by config option disassoc_low_ack. * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad config file. * WPS: - Send AP Settings as a wrapped Credential attribute to ctrl_iface in WPS-NEW-AP-SETTINGS. - Dispatch more WPS events through hostapd ctrl_iface. - Add mechanism for indicating non-standard WPS errors. - Change concurrent radio AP to use only one WPS UPnP instance. - Add wps_check_pin command for processing PIN from user input. UIs can use this command to process a PIN entered by a user and to validate the checksum digit (if present). - Add hostap_cli get_config command to display current AP config. - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at runtime and support dynamic AP PIN management. - Disable AP PIN after 10 consecutive failures. Slow down attacks on failures up to 10. - Allow AP to start in Enrollee mode without AP PIN for probing, to be compatible with Windows 7. - Add Config Error into WPS-FAIL events to provide more info to the user on how to resolve the issue. - When controlling multiple interfaces: - apply WPS commands to all interfaces configured to use WPS - apply WPS config changes to all interfaces that use WPS - when an attack is detected on any interface, disable AP PIN on all interfaces * WPS ER: - Show SetSelectedRegistrar events as ctrl_iface events. - Add special AP Setup Locked mode to allow read only ER. ap_setup_locked=2 can now be used to enable a special mode where WPS ER can learn the current AP settings, but cannot change them. * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool for testing protocol extensibility. - Add build option CONFIG_WPS_STRICT to allow disabling of WPS workarounds. - Add support for AuthorizedMACs attribute. * TDLS: - Allow TDLS use or TDLS channel switching in the BSS to be prohibited in the BSS, using config params tdls_prohibit and tdls_prohibit_chan_switch. * EAP server: Add support for configuring fragment size (see fragment_size in hostapd.conf). * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. wlantest can be used to capture frames from a monitor interface for realtime capturing or from pcap files for offline analysis. * Interworking: Support added for 802.11u. Enable in .config with CONFIG_INTERWORKING. See hostapd.conf for config parameters for interworking. * Android: Add build and runtime support for Android hostapd. * Add a new debug message level for excessive information. Use -ddd to enable. * TLS: Add support for tls_disable_time_checks=1 in client mode. * Internal TLS: - Add support for TLS v1.1 (RFC 4346). Enable with build parameter CONFIG_TLSV11. - Add domainComponent parser for X.509 names * Reorder some IEs to get closer to IEEE 802.11 standard. Move WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. Move HT IEs to be later in (Re)Assoc Resp. * Many bugfixes.

Import wpa_supplicant / hostapd 0.7.3. Changes: 2010-09-07 - v0.7.3 * fixed fallback from failed PMKSA caching into full EAP authentication [Bug 355] * fixed issue with early D-Bus signals during initialization * fixed X.509 name handling in internal TLS * fixed WPS ER to use corrent Enrollee MAC Address in Credential * fixed scanning routines ot improve AP selection for WPS * added WPS workaround for open networks * fixed WPS Diffie-Hellman derivation to use correct public key length * fixed wpa_supplicant AP mode operations to ignore Supplicant and scan result events * improved SME operations with nl80211 * fixed WPS ER event_id handling in some cases * fixed some issues with bgscan simple to avoid unnecessary scans * fixed issue with l2_packet_ndis overlapped writes corrupting stack [Bug 328] * updated WinPcap to the latest stable version 4.1.2 in Windows installer 2010-04-18 - v0.7.2 * nl80211: fixed number of issues with roaming * avoid unnecessary roaming if multiple APs with similar signal strength are present in scan results * add TLS client events and server probing to ease design of automatic detection of EAP parameters * add option for server certificate matching (SHA256 hash of the certificate) instead of trusted CA certificate configuration * bsd: Cleaned up driver wrapper and added various low-level configuration options * wpa_gui-qt4: do not show too frequent WPS AP available events as tray messages * 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) * wpa_cli: added option for using a separate process to receive event messages to reduce latency in showing these (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) * maximum BSS table size can now be configured (bss_max_count) * BSSes to be included in the BSS table can be filtered based on configured SSIDs to save memory (filter_ssids) * fix number of issues with IEEE 802.11r/FT;

the first one that is able to initialize the interface will be used * added support for multiple SSIDs per scan request to optimize scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden SSIDs); this requires driver support and can currently be used only with nl80211 * added support for WPS USBA out-of-band mechanism with USB Flash Drives (UFD) (CONFIG_WPS_UFD=y) * driver_ndis: add PAE group address to the multicast address list to fix wired IEEE 802.1X authentication * fixed IEEE 802.11r key derivation function to match with the standard (note: this breaks interoperability with previous version) [Bug 303] * added better support for drivers that allow separate authentication and association commands (e.g., mac80211-based Linux drivers with nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol to be used (IEEE 802.11r) * 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] * use shared driver wrapper files with hostapd * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network block; this can be used for open and WPA2-Personal networks (optionally, with WPS); this links in parts of hostapd functionality into wpa_supplicant * wpa_gui-qt4: added new Peers dialog to show information about peers (other devices, including APs and stations, etc. in the neighborhood) * added support for WPS External Registrar functionality (configure APs and enroll new devices); can be used with wpa_gui-qt4 Peers dialog and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, wps_er_pbc, wps_er_learn (this can also be used with a new 'none' driver wrapper if no wireless device or IEEE 802.1X on wired is needed) * 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 support for NFC out-of-band mechanism with WPS * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group address frames * added preliminary support for IEEE 802.11r RIC processing * added support for specifying subset of enabled frequencies to scan (scan_freq option in the network configuration block);

this version is not backwards compatible with old versions * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air and over-the-DS) * add freq_list network configuration parameter to allow the AP selection to filter out entries based on the operating channel * add signal strength change events for bgscan; this allows more dynamic changes to background scanning interval based on changes in the signal strength with the current AP; this improves roaming within ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network configuration block to request background scans less frequently when signal strength remains good and to automatically trigger background scans whenever signal strength drops noticeably (this is currently only available with nl80211) * add BSSID and reason code (if available) to disconnect event messages * wpa_gui-qt4: more complete support for translating the GUI with linguist and add German translation * fix DH padding with internal crypto code (mainly, for WPS) * do not trigger initial scan automatically anymore if there are no enabled networks 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 * nl80211: use explicit deauthentication to clear cfg80211 state to avoid issues when roaming between APs * dbus: major design changes in the new D-Bus API (fi.w1.wpa_supplicant1) * nl80211: added support for IBSS networks * added internal debugging mechanism with backtrace support and memory allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) * added WPS ER unsubscription command to more cleanly unregister from receiving UPnP events when ER is terminated * cleaned up AP mode operations to avoid need for virtual driver_ops wrapper * added BSS table to maintain more complete scan result information over multiple scans (that may include only partial results) * wpa_gui-qt4: update Peers dialog information more dynamically while the dialog is kept open * fixed PKCS#12 use with OpenSSL 1.0.0 * driver_wext: Added cfg80211-specific optimization to avoid some unnecessary scans and to speed up association 2009-11-21 - v0.7.0 * increased wpa_cli ping interval to 5 seconds and made this configurable with a new command line options (-G<seconds>) * fixed scan buffer processing with WEXT to handle up to 65535 byte result buffer (previously, limited to 32768 bytes) * allow multiple driver wrappers to be specified on command line (e.g., -Dnl80211,wext); the first one that is able to initialize the interface will be used * added support for multiple SSIDs per scan request to optimize scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden SSIDs); this requires driver support and can currently be used only with nl80211 * added support for WPS USBA out-of-band mechanism with USB Flash Drives (UFD) (CONFIG_WPS_UFD=y) * driver_ndis: add PAE group address to the multicast address list to fix wired IEEE 802.1X authentication * fixed IEEE 802.11r key derivation function to match with the standard (note: this breaks interoperability with previous version) [Bug 303] * added better support for drivers that allow separate authentication and association commands (e.g., mac80211-based Linux drivers with nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol to be used (IEEE 802.11r) * 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] * use shared driver wrapper files with hostapd * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network block; this can be used for open and WPA2-Personal networks (optionally, with WPS); this links in parts of hostapd functionality into wpa_supplicant * wpa_gui-qt4: added new Peers dialog to show information about peers (other devices, including APs and stations, etc. in the neighborhood) * added support for WPS External Registrar functionality (configure APs and enroll new devices); can be used with wpa_gui-qt4 Peers dialog and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, wps_er_pbc, wps_er_learn (this can also be used with a new 'none' driver wrapper if no wireless device or IEEE 802.1X on wired is needed) * 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 support for NFC out-of-band mechanism with WPS * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group address frames * added preliminary support for IEEE 802.11r RIC processing * added support for specifying subset of enabled frequencies to scan (scan_freq option in the network configuration block); this can speed up scanning process considerably if it is known that only a small subset of channels is actually used in the network (this is currently supported only with -Dnl80211) * added a workaround for race condition between receiving the association event and the following EAPOL-Key * added background scan and roaming infrastructure to allow network-specific optimizations to be used to improve roaming within an ESS (same SSID) * added new DBus interface (fi.w1.wpa_supplicant1)

See hostapd.conf. * Add support for IEEE 802.11v Time Advertisement mechanism with UTC TSF offset. See hostapd.conf for config info. * Delay STA entry removal until Deauth/Disassoc TX status in AP mode. This allows the driver to use PS buffering of Deauthentication and Disassociation frames when the STA is in power save sleep. Only available with drivers that provide TX status events for Deauth/ Disassoc frames (nl80211). * Allow PMKSA caching to be disabled on the Authenticator. See hostap.conf config parameter disable_pmksa_caching. * atheros: Add support for IEEE 802.11w configuration. * bsd: Add support for setting HT values in IFM_MMASK. * Allow client isolation to be configured with ap_isolate. Client isolation can be used to prevent low-level bridging of frames between associated stations in the BSS. By default, this bridging is allowed. * Allow coexistance of HT BSSes with WEP/TKIP BSSes. * Add require_ht config parameter, which can be used to configure hostapd to reject association with any station that does not support HT PHY. * Add support for writing debug log to a file using "-f" option. Also add relog CLI command to re-open the log file. * Add bridge handling for WDS STA interfaces. By default they are added to the configured bridge of the AP interface (if present), but the user can also specify a separate bridge using cli command wds_bridge. * hostapd_cli: - Add wds_bridge command for specifying bridge for WDS STA interfaces. - Add relog command for reopening log file. - Send AP-STA-DISCONNECTED event when an AP disconnects a station due to inactivity. - Add wps_config ctrl_interface command for configuring AP.

It works in the same way as new AP settings received from an ER. - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. - Add command get version, that returns hostapd version string. * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. Use hostapd_cli ess_disassoc (STA addr) (URL) to send the notification to the STA. * Allow AP mode to disconnect STAs based on low ACK condition (when the data connection is not working properly, e.g., due to the STA going outside the range of the AP). Disabled by default, enable by config option disassoc_low_ack. * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad config file. * WPS: - Send AP Settings as a wrapped Credential attribute to ctrl_iface in WPS-NEW-AP-SETTINGS. - Dispatch more WPS events through hostapd ctrl_iface. - Add mechanism for indicating non-standard WPS errors. - Change concurrent radio AP to use only one WPS UPnP instance. - Add wps_check_pin command for processing PIN from user input. UIs can use this command to process a PIN entered by a user and to validate the checksum digit (if present). - Add hostap_cli get_config command to display current AP config. - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at runtime and support dynamic AP PIN management. - Disable AP PIN after 10 consecutive failures. Slow down attacks on failures up to 10. - Allow AP to start in Enrollee mode without AP PIN for probing, to be compatible with Windows 7. - Add Config Error into WPS-FAIL events to provide more info to the user on how to resolve the issue. - When controlling multiple interfaces: - apply WPS commands to all interfaces configured to use WPS - apply WPS config changes to all interfaces that use WPS - when an attack is detected on any interface, disable AP PIN on all interfaces * WPS ER: - Show SetSelectedRegistrar events as ctrl_iface events. - Add special AP Setup Locked mode to allow read only ER. ap_setup_locked=2 can now be used to enable a special mode where WPS ER can learn the current AP settings, but cannot change them. * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool for testing protocol extensibility. - Add build option CONFIG_WPS_STRICT to allow disabling of WPS workarounds. - Add support for AuthorizedMACs attribute. * TDLS: - Allow TDLS use or TDLS channel switching in the BSS to be prohibited in the BSS, using config params tdls_prohibit and tdls_prohibit_chan_switch. * EAP server: Add support for configuring fragment size (see fragment_size in hostapd.conf). * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. wlantest can be used to capture frames from a monitor interface for realtime capturing or from pcap files for offline analysis. * Interworking: Support added for 802.11u. Enable in .config with CONFIG_INTERWORKING. See hostapd.conf for config parameters for interworking. * Android: Add build and runtime support for Android hostapd. * Add a new debug message level for excessive information. Use -ddd to enable. * TLS: Add support for tls_disable_time_checks=1 in client mode. * Internal TLS: - Add support for TLS v1.1 (RFC 4346). Enable with build parameter CONFIG_TLSV11. - Add domainComponent parser for X.509 names * Reorder some IEs to get closer to IEEE 802.11 standard. Move WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. Move HT IEs to be later in (Re)Assoc Resp. * Many bugfixes.

this requires driver support and can currently be used only with nl80211 * added support for WPS USBA out-of-band mechanism with USB Flash Drives (UFD) (CONFIG_WPS_UFD=y) * driver_ndis: add PAE group address to the multicast address list to fix wired IEEE 802.1X authentication * fixed IEEE 802.11r key derivation function to match with the standard (note: this breaks interoperability with previous version) [Bug 303] * added better support for drivers that allow separate authentication and association commands (e.g., mac80211-based Linux drivers with nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol to be used (IEEE 802.11r) * 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] * use shared driver wrapper files with hostapd * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network block; this can be used for open and WPA2-Personal networks (optionally, with WPS); this links in parts of hostapd functionality into wpa_supplicant * wpa_gui-qt4: added new Peers dialog to show information about peers (other devices, including APs and stations, etc. in the neighborhood) * added support for WPS External Registrar functionality (configure APs and enroll new devices); can be used with wpa_gui-qt4 Peers dialog and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, wps_er_pbc, wps_er_learn (this can also be used with a new 'none' driver wrapper if no wireless device or IEEE 802.1X on wired is needed) * 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 support for NFC out-of-band mechanism with WPS * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group address frames * added preliminary support for IEEE 802.11r RIC processing * added support for specifying subset of enabled frequencies to scan (scan_freq option in the network configuration block);

See hostapd.conf. * Add support for IEEE 802.11v Time Advertisement mechanism with UTC TSF offset. See hostapd.conf for config info. * Delay STA entry removal until Deauth/Disassoc TX status in AP mode. This allows the driver to use PS buffering of Deauthentication and Disassociation frames when the STA is in power save sleep. Only available with drivers that provide TX status events for Deauth/ Disassoc frames (nl80211). * Allow PMKSA caching to be disabled on the Authenticator. See hostap.conf config parameter disable_pmksa_caching. * atheros: Add support for IEEE 802.11w configuration. * bsd: Add support for setting HT values in IFM_MMASK. * Allow client isolation to be configured with ap_isolate. Client isolation can be used to prevent low-level bridging of frames between associated stations in the BSS. By default, this bridging is allowed. * Allow coexistance of HT BSSes with WEP/TKIP BSSes. * Add require_ht config parameter, which can be used to configure hostapd to reject association with any station that does not support HT PHY. * Add support for writing debug log to a file using "-f" option. Also add relog CLI command to re-open the log file. * Add bridge handling for WDS STA interfaces. By default they are added to the configured bridge of the AP interface (if present), but the user can also specify a separate bridge using cli command wds_bridge. * hostapd_cli: - Add wds_bridge command for specifying bridge for WDS STA interfaces. - Add relog command for reopening log file. - Send AP-STA-DISCONNECTED event when an AP disconnects a station due to inactivity. - Add wps_config ctrl_interface command for configuring AP. This command can be used to configure the AP using the internal WPS registrar. It works in the same way as new AP settings received from an ER. - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. - Add command get version, that returns hostapd version string. * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. Use hostapd_cli ess_disassoc (STA addr) (URL) to send the notification to the STA. * Allow AP mode to disconnect STAs based on low ACK condition (when the data connection is not working properly, e.g., due to the STA going outside the range of the AP). Disabled by default, enable by config option disassoc_low_ack. * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad config file. * WPS: - Send AP Settings as a wrapped Credential attribute to ctrl_iface in WPS-NEW-AP-SETTINGS. - Dispatch more WPS events through hostapd ctrl_iface. - Add mechanism for indicating non-standard WPS errors. - Change concurrent radio AP to use only one WPS UPnP instance. - Add wps_check_pin command for processing PIN from user input. UIs can use this command to process a PIN entered by a user and to validate the checksum digit (if present). - Add hostap_cli get_config command to display current AP config. - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at runtime and support dynamic AP PIN management. - Disable AP PIN after 10 consecutive failures. Slow down attacks on failures up to 10. - Allow AP to start in Enrollee mode without AP PIN for probing, to be compatible with Windows 7. - Add Config Error into WPS-FAIL events to provide more info to the user on how to resolve the issue. - When controlling multiple interfaces: - apply WPS commands to all interfaces configured to use WPS - apply WPS config changes to all interfaces that use WPS - when an attack is detected on any interface, disable AP PIN on all interfaces * WPS ER: - Show SetSelectedRegistrar events as ctrl_iface events. - Add special AP Setup Locked mode to allow read only ER. ap_setup_locked=2 can now be used to enable a special mode where WPS ER can learn the current AP settings, but cannot change them. * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool for testing protocol extensibility. - Add build option CONFIG_WPS_STRICT to allow disabling of WPS workarounds. - Add support for AuthorizedMACs attribute. * TDLS: - Allow TDLS use or TDLS channel switching in the BSS to be prohibited in the BSS, using config params tdls_prohibit and tdls_prohibit_chan_switch. * EAP server: Add support for configuring fragment size (see fragment_size in hostapd.conf). * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. wlantest can be used to capture frames from a monitor interface for realtime capturing or from pcap files for offline analysis. * Interworking: Support added for 802.11u. Enable in .config with CONFIG_INTERWORKING. See hostapd.conf for config parameters for interworking. * Android: Add build and runtime support for Android hostapd. * Add a new debug message level for excessive information. Use -ddd to enable. * TLS: Add support for tls_disable_time_checks=1 in client mode. * Internal TLS: - Add support for TLS v1.1 (RFC 4346). Enable with build parameter CONFIG_TLSV11. - Add domainComponent parser for X.509 names * Reorder some IEs to get closer to IEEE 802.11 standard. Move WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. Move HT IEs to be later in (Re)Assoc Resp. * Many bugfixes.

Import wpa_supplicant / hostapd 0.7.3. Changes: 2010-09-07 - v0.7.3 * fixed fallback from failed PMKSA caching into full EAP authentication [Bug 355] * fixed issue with early D-Bus signals during initialization * fixed X.509 name handling in internal TLS * fixed WPS ER to use corrent Enrollee MAC Address in Credential * fixed scanning routines ot improve AP selection for WPS * added WPS workaround for open networks * fixed WPS Diffie-Hellman derivation to use correct public key length * fixed wpa_supplicant AP mode operations to ignore Supplicant and scan result events * improved SME operations with nl80211 * fixed WPS ER event_id handling in some cases * fixed some issues with bgscan simple to avoid unnecessary scans * fixed issue with l2_packet_ndis overlapped writes corrupting stack [Bug 328] * updated WinPcap to the latest stable version 4.1.2 in Windows installer 2010-04-18 - v0.7.2 * nl80211: fixed number of issues with roaming * avoid unnecessary roaming if multiple APs with similar signal strength are present in scan results * add TLS client events and server probing to ease design of automatic detection of EAP parameters * add option for server certificate matching (SHA256 hash of the certificate) instead of trusted CA certificate configuration * bsd: Cleaned up driver wrapper and added various low-level configuration options * wpa_gui-qt4: do not show too frequent WPS AP available events as tray messages * 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) * wpa_cli: added option for using a separate process to receive event messages to reduce latency in showing these (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) * maximum BSS table size can now be configured (bss_max_count) * BSSes to be included in the BSS table can be filtered based on configured SSIDs to save memory (filter_ssids) * fix number of issues with IEEE 802.11r/FT;
