ChangeLog for hostapd
2010-01-12 - v0.6.10
* 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]
* fixed WPS selected registrar expiration for internal PIN registrar
* disable PMTU discovery for RADIUS packets
* fixed WPS UPnP SSDP on 32-bit targets
* fixed WPS AP reconfiguration with drivers that do not use hostapd
MLME
* fixed RSN parameter setting for multi-BSS case
* added WPS workarounds for known interoperability issues with broken,
deployed implementation
* update IEEE 802.11w implementation to match with the published
standard
* fixed OpCode when proxying WSC_ACK or WSC_NACK from WPS ER
* fixed proxying of WSC_NACK to WPS ER
* fixed compilation with newer GnuTLS versions
* added support for defining timeout for WPS PINs
* fixed WPS Probe Request processing to handle missing required
attribute
* fixed PKCS#12 use with OpenSSL 1.0.0
2009-03-23 - v0.6.9
* driver_nl80211: fixed STA accounting data collection (TX/RX bytes
reported correctly; TX/RX packets not yet available from kernel)
* fixed EAPOL/EAP reauthentication when using an external RADIUS
authentication server
* driver_prism54: fixed segmentation fault on initialization
* 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]
2009-02-15 - v0.6.8
* increased hostapd_cli ping interval to 5 seconds and made this
configurable with a new command line options (-G<seconds>)

To reduce likelihood of PIN being used with other devices or of

After this, the Enrollee can connect to the AP again and complete WPS

* ieee80211_radiotap_iterator_init - radiotap parser iterator initialization
* @iterator: radiotap_iterator to initialize
* @radiotap_header: radiotap header to parse
* @max_length: total length we can parse into (eg, whole packet length)
*
* Returns: 0 or a negative error code if there is a problem.
*
* This function initializes an opaque iterator struct which can then
* be passed to ieee80211_radiotap_iterator_next() to visit every radiotap
* argument which is present in the header. It knows about extended
* present headers and handles them.
*
* How to use:
* call __ieee80211_radiotap_iterator_init() to init a semi-opaque iterator
* struct ieee80211_radiotap_iterator (no need to init the struct beforehand)
* checking for a good 0 return code. Then loop calling
* __ieee80211_radiotap_iterator_next()... it returns either 0,
* -ENOENT if there are no more args to parse, or -EINVAL if there is a problem.
* The iterator's @this_arg member points to the start of the argument
* associated with the current argument index that is present, which can be
* found in the iterator's @this_arg_index member. This arg index corresponds
* to the IEEE80211_RADIOTAP_... defines.
*
* Radiotap header length:
* You can find the CPU-endian total radiotap header length in
* iterator->max_length after executing ieee80211_radiotap_iterator_init()
* successfully.
*
* Alignment Gotcha:
* You must take care when dereferencing iterator.this_arg
* for multibyte types... the pointer is not aligned. Use
* get_unaligned((type *)iterator.this_arg) to dereference
* iterator.this_arg for type "type" safely on all arches.
*
* Example code:
* See Documentation/networking/radiotap-headers.txt

* @max_length: total length we can parse into (eg, whole packet length)
*
* Returns: 0 or a negative error code if there is a problem.
*
* This function initializes an opaque iterator struct which can then
* be passed to ieee80211_radiotap_iterator_next() to visit every radiotap
* argument which is present in the header. It knows about extended
* present headers and handles them.
*
* How to use:
* call __ieee80211_radiotap_iterator_init() to init a semi-opaque iterator
* struct ieee80211_radiotap_iterator (no need to init the struct beforehand)
* checking for a good 0 return code. Then loop calling
* __ieee80211_radiotap_iterator_next()... it returns either 0,
* -ENOENT if there are no more args to parse, or -EINVAL if there is a problem.
* The iterator's @this_arg member points to the start of the argument
* associated with the current argument index that is present, which can be
* found in the iterator's @this_arg_index member. This arg index corresponds
* to the IEEE80211_RADIOTAP_... defines.
*
* Radiotap header length:
* You can find the CPU-endian total radiotap header length in
* iterator->max_length after executing ieee80211_radiotap_iterator_init()
* successfully.
*
* Alignment Gotcha:
* You must take care when dereferencing iterator.this_arg
* for multibyte types... the pointer is not aligned. Use
* get_unaligned((type *)iterator.this_arg) to dereference
* iterator.this_arg for type "type" safely on all arches.
*
* Example code:
* See Documentation/networking/radiotap-headers.txt
