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

.TH HOSTAPD 8 "April 7, 2005" hostapd hostapd
.SH NAME
hostapd \- IEEE 802.11 AP, IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator
.SH SYNOPSIS
.B hostapd
[\-hdBKtv] [\-P <PID file>] <configuration file(s)>
.SH DESCRIPTION
This manual page documents briefly the
.B hostapd
daemon.
.PP
.B hostapd
is a user space daemon for access point and authentication servers.
It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators and RADIUS authentication server.
The current version supports Linux (Host AP, madwifi, mac80211-based drivers) and FreeBSD (net80211).
.B hostapd
is designed to be a "daemon" program that runs in the background and acts as the backend component controlling authentication.
.B hostapd
supports separate frontend programs and an example text-based frontend,
.BR hostapd_cli ,
is included with
.BR hostapd .
.SH OPTIONS
A summary of options is included below.
For a complete description, run
.BR hostapd
