4.17-stable review patch. If anyone has any objections, please let me know. ------------------ From: Tudor-Dan Ambarus <tudor.ambarus@xxxxxxxxxxxxx> [ Upstream commit ad2fdcdf75d169e7a5aec6c7cb421c0bec8ec711 ] In crypto_authenc_setkey we save pointers to the authenc keys in a local variable of type struct crypto_authenc_keys and we don't zeroize it after use. Fix this and don't leak pointers to the authenc keys.
