	  use of the Secure bit in EAPOL-Key msg 3/4
	* fixed number of small bugs (see git logs for more details)
	* changed OpenSSL to read full certificate chain from server_cert file
	* nl80211: number of updates to use new cfg80211/nl80211 functionality

	* increased initial group key handshake retransmit timeout to 500 ms
	* added a workaround for 4-way handshake to update SNonce even after
	  having sent EAPOL-Key 3/4 to avoid issues with some supplicant
	  implementations that can change SNonce for each EAP-Key 2/4
	* added a workaround for EAPOL-Key 4/4 using incorrect type value in
	  WPA2 mode (some deployed stations use WPA type in that message)
	* added a WPS workaround for mixed mode AP Settings with Windows 7
	* changed WPS AP PIN disabling mechanism to disable the PIN after 10
	  consecutive failures in addition to using the exponential lockout
	  period

	* added support for canceling WPS operations with hostapd_cli wps_cancel
	* fixed EAP/WPS to PSK transition on reassociation in cases where
	  deauthentication is missed
	* hlr_auc_gw enhancements:
	  - a new command line parameter -u can be used to enable updating of
	    SQN in Milenage file
	  - use 5 bit IND for SQN updates
	  - SQLite database can now be used to store Milenage information
	* EAP-SIM/AKA DB: added optional use of SQLite database for pseudonyms
	  and reauth data
	* added support for Chargeable-User-Identity (RFC 4372)
	* added radius_auth_req_attr and radius_acct_req_attr configuration
	  parameters to allow adding/overriding of RADIUS attributes in
	  Access-Request and Accounting-Request packets

	* added support for 256-bit AES with internal TLS implementation
	* changed EAPOL transmission to use AC_VO if WMM is active
	* fixed EAP-TLS/PEAP/TTLS/FAST server to validate TLS Message Length
	  correctly; invalid messages could have caused the hostapd process to
	  terminate before this fix [CVE-2012-4445]
	* limit number of active wildcard PINs for WPS Registrar to one to avoid
	  confusing behavior with multiple wildcard PINs
	* added a workaround for WPS PBC session overlap detection to avoid
	  interop issues with deployed station implementations that do not
	  remove active PBC indication from Probe Request frames properly
	* added support for using SQLite for the eap_user database
	* added Acct-Session-Id attribute into Access-Request messages
	* fixed EAPOL frame transmission to non-QoS STAs with nl80211
	  (do not send QoS frames if the STA did not negotiate use of QoS for
	  this association)

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.
	* 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.

Disable debugging.
The mbox driver is actually MP safe, so set the right flag in
bus_setup_intr().
Update to current configuration.
If you've compiled your base system with WITH_ICONV, then use it for svn
alongside the other consumers (bsdtar, csh etc).

The svnlite build gets upset when it hits non-ascii characters in
inconvenient places.
__weak_alias() doesn't exist on FreeBSD.  Use __weak_reference();

Expose iconv functions as weak symbols as well as their internal
remapped #define names.  This is necessary for autoconf compatability -
on Linux it appears that #include <iconv.h> isn't a link time
prerequisite for their version that's built into glibc.

Initialize the pthread rwlock.  Note that upstream has three
separate locks.  The file-local static lock appears intentional.

I'm using this as a ports-compatible compile-time substitute for
converters/libiconv on one of my personal machines.
If strdup failed, don't try and free the wrong thing.
Change i_gen in UFS to an unsigned type.

Further simplify the i_gen calculation for older disks.
Having a zero here is not really a problem and this is more
similar to what is done in newfs_random().
