IEEE 802.11r KDF uses key length in the derivation and as such, the PTK length must be specified correctly. The previous version was deriving using 512-bit PTK regardless of the negotiated cipher suite; this works for TKIP, but not for CCMP. Update the code to use proper PTK length based on the pairwise cipher. This fixed PTK derivation for both IEEE 802.11r and IEEE 802.11w (when using AKMP that specifies SHA-256-based key derivation). The fixed version does not interoperate with the previous versions. [Bug 307]
wpa_supplicant and hostapd v0.6.x --------------------------------- Copyright (c) 2002-2007, Jouni Malinen <j@w1.fi> and contributors All Rights Reserved. These program is dual-licensed under both the GPL version 2 and BSD license. Either license may be used at your option. This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files have been moved around in v0.6.x releases and compared to earlier releases, the programs are now build by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
