4.17-stable review patch. If anyone has any objections, please let me know. ------------------ From: Tudor-Dan Ambarus <tudor.ambarus@xxxxxxxxxxxxx> [ Upstream commit 31545df391d58a3bb60e29b1192644a6f2b5a8dd ] In crypto_authenc_esn_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.
