Jouni Malinen	31bc66e4d1	More forceful clearing of stack memory with keys ... gcc 8.3.0 was apparently clever enough to optimize away the previously used os_memset() to explicitly clear a stack buffer that contains keys when that clearing happened just before returning from the function. Since memset_s() is not exactly portable (or commonly available yet..), use a less robust mechanism that is still pretty likely to prevent current compilers from optimizing the explicit clearing of the memory away.

Jouni Malinen	ef23838590	Return success/failure result from sha384_prf() ... This makes the function more consistent with sha256_prf(). Signed-off-by: Jouni Malinen <j@w1.fi>	2017-03-12 20:43:06 +02:00
Jouni Malinen	d9c807cab1	Fix key derivation for Suite B 192-bit AKM to use SHA384 ... While the EAPOL-Key MIC derivation was already changed from SHA256 to SHA384 for the Suite B 192-bit AKM, KDF had not been updated similarly. Fix this by using HMAC-SHA384 instead of HMAC-SHA256 when deriving PTK from PMK when using the Suite B 192-bit AKM. Signed-off-by: Jouni Malinen <j@w1.fi>	2015-08-27 20:42:14 +03:00
