+
+2014-10-09 - v2.3
+ * fixed number of minor issues identified in static analyzer warnings
+ * fixed DFS and channel switch operation for multi-BSS cases

+ values to reduce possibility of any externally measurable timing
+ differences
+ * extended explicit clearing of freed memory and expired keys to avoid
+ keeping private data in memory longer than necessary
+ * added support for number of new RADIUS attributes from RFC 7268
+ (Mobility-Domain-Id, WLAN-HESSID, WLAN-Pairwise-Cipher,
+ WLAN-Group-Cipher, WLAN-AKM-Suite, WLAN-Group-Mgmt-Pairwise-Cipher)
+ * fixed GET_CONFIG wpa_pairwise_cipher value
+ * added code to clear bridge FDB entry on station disconnection
+ * fixed PMKSA cache timeout from Session-Timeout for WPA/WPA2 cases

+ in case the first entry does not match
+ * fixed hostapd_cli action script execution to use more robust mechanism
+ (CVE-2014-3686)
+
+2014-06-04 - v2.2
+ * fixed SAE confirm-before-commit validation to avoid a potential
+ segmentation fault in an unexpected message sequence that could be
+ triggered remotely
+ * extended VHT support
+ - Operating Mode Notification
+ - Power Constraint element (local_pwr_constraint)
+ - Spectrum management capability (spectrum_mgmt_required=1)
+ - fix VHT80 segment picking in ACS
+ - fix vht_capab 'Maximum A-MPDU Length Exponent' handling
+ - fix VHT20
+ * fixed HT40 co-ex scan for some pri/sec channel switches
+ * extended HT40 co-ex support to allow dynamic channel width changes
+ during the lifetime of the BSS
+ * fixed HT40 co-ex support to check for overlapping 20 MHz BSS
+ * fixed MSCHAP UTF-8 to UCS-2 conversion for three-byte encoding;
+ this fixes password with include UTF-8 characters that use
+ three-byte encoding EAP methods that use NtPasswordHash
+ * reverted TLS certificate validation step change in v2.1 that rejected
+ any AAA server certificate with id-kp-clientAuth even if
+ id-kp-serverAuth EKU was included
+ * fixed STA validation step for WPS ER commands to prevent a potential
+ crash if an ER sends an unexpected PutWLANResponse to a station that
+ is disassociated, but not fully removed
+ * enforce full EAP authentication after RADIUS Disconnect-Request by
+ removing the PMKSA cache entry
+ * added support for NAS-IP-Address, NAS-identifier, and NAS-IPv6-Address
+ in RADIUS Disconnect-Request
+ * added mechanism for removing addresses for MAC ACLs by prefixing an
+ entry with "-"
+ * Interworking/Hotspot 2.0 enhancements
+ - support Hotspot 2.0 Release 2
+ * OSEN network for online signup connection
+ * subscription remediation (based on RADIUS server request or
+ control interface HS20_WNM_NOTIF for testing purposes)
+ * Hotspot 2.0 release number indication in WFA RADIUS VSA
+ * deauthentication request (based on RADIUS server request or
+ control interface WNM_DEAUTH_REQ for testing purposes)
+ * Session Info URL RADIUS AVP to trigger ESS Disassociation Imminent
+ * hs20_icon config parameter to configure icon files for OSU
+ * osu_* config parameters for OSU Providers list
+ - do not use Interworking filtering rules on Probe Request if
+ Interworking is disabled to avoid interop issues
+ * added/fixed nl80211 functionality
+ - AP interface teardown optimization
+ - support vendor specific driver command
+ (VENDOR <vendor id> <sub command id> [<hex formatted data>])
+ * fixed PMF protection of Deauthentication frame when this is triggered
+ by session timeout

+ - add SHA256-based cipher suites
+ - add DHE-RSA cipher suites
+ - fix X.509 validation of PKCS#1 signature to check for extra data
+ * RADIUS server functionality
+ - add minimal RADIUS accounting server support (hostapd-as-server);
+ this is mainly to enable testing coverage with hwsim scripts
+ - allow authentication log to be written into SQLite databse
+ - added option for TLS protocol testing of an EAP peer by simulating
+ various misbehaviors/known attacks
+ - MAC ACL support for testing purposes
+ * fixed PTK derivation for CCMP-256 and GCMP-256
+ * extended WPS per-station PSK to support ER case
+ * added option to configure the management group cipher
+ (group_mgmt_cipher=AES-128-CMAC (default), BIP-GMAC-128, BIP-GMAC-256,
+ BIP-CMAC-256)
+ * fixed AP mode default TXOP Limit values for AC_VI and AC_VO (these
+ were rounded incorrectly)
+ * added support for postponing FT response in case PMK-R1 needs to be
+ pulled from R0KH
+ * added option to advertise 40 MHz intolerant HT capability with
+ ht_capab=[40-INTOLERANT]
+ * remove WPS 1.0 only support, i.e., WSC 2.0 support is now enabled
+ whenever CONFIG_WPS=y is set
+ * EAP-pwd fixes
+ - fix possible segmentation fault on EAP method deinit if an invalid
+ group is negotiated
+ * fixed RADIUS client retransmit/failover behavior
+ - there was a potential ctash due to freed memory being accessed
+ - failover to a backup server mechanism did not work properly
+ * fixed a possible crash on double DISABLE command when multiple BSSes
+ are enabled
+ * fixed a memory leak in SAE random number generation
+ * fixed GTK rekeying when the station uses FT protocol
+ * fixed off-by-one bounds checking in printf_encode()
+ - this could result in deinial of service in some EAP server cases
+ * various bug fixes
+
2014-02-04 - v2.1
* added support for simultaneous authentication of equals (SAE) for
stronger password-based authentication with WPA2-Personal
