This patch fixes several issues in security: 1) the uCode doesn't know about TKIP-MMIC failure, if uCode set RX_RES_STATUS_BAD_ICV_MIC, it means ICV failure: drop the packet silently. 2) do not allocate room in the key table of the uCode is the set_key call is a replacement of an old key 3) check the keyidx of the key in the uCode before removing it upon disable_key call Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: John W.
