2012-05-10 - v1.0
* Add channel selection support in hostapd. See hostapd.conf.
* Add support for IEEE 802.11v Time Advertisement mechanism with UTC
TSF offset. See hostapd.conf for config info.

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

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.

interfaces.
- Add relog command for reopening log file.
- Send AP-STA-DISCONNECTED event when an AP disconnects a station
due to inactivity.

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.

- 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.

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)

* 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)

(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)
require the authenticator announce EAPOL version 1 don't have to hack
the code to get a working setup.
Discussed with Jouni; he's committed a similar set of changes to
his devel branch and I sent him these changes so I'm committing
this on the vendor branch in the expectation it will appear in
the next import.
MFC after: 1 week
version has a bug where it fails to properly cancel the polling loop
that periodically queries the BSSID (this is done to detect the
association/disassociation state). The timeout is supposed to fire
once a second, but the eloop_cancel_timeout() call uses a different
'user data' value than what was passed to eloop_register_timeout(),
so cancelling the timeouts fails. This results in an additional timeout
being created each time an EAPOL packet is received, which can lead
to dozens of unwanted timeouts firing every second instead of just one.
