The new AES en/decryption functions are also much faster\nand use AES instructions when supported by the CPU.\n\nNote that in addition to the change in the key preparation function and\nthe key struct type itself, the change in the type of the key struct\nresults in aes_encrypt() (which is temporarily a type-generic macro)\ncalling the new encryption function rather than the old one.\n\nAcked-by: Ard Biesheuvel <ardb@kernel.org>\nSigned-off-by: Eric Biggers <ebiggers@kernel.org>\n---\n drivers/net/phy/mscc/mscc_macsec.c | 8 ++++----\n 1 file changed, 4 insertions(+), 4 deletions(-)", "diff": "diff --git a/drivers/net/phy/mscc/mscc_macsec.c b/drivers/net/phy/mscc/mscc_macsec.c\nindex 4f39ba63a9a9..9a38a29cf397 100644\n--- a/drivers/net/phy/mscc/mscc_macsec.c\n+++ b/drivers/net/phy/mscc/mscc_macsec.c\n@@ -502,19 +502,19 @@ static u32 vsc8584_macsec_flow_context_id(struct macsec_flow *flow)\n \n /* Derive the AES key to get a key for the hash autentication */\n static int vsc8584_macsec_derive_key(const u8 *key, u16 key_len, u8 hkey[16])\n {\n \tconst u8 input[AES_BLOCK_SIZE] = {0};\n-\tstruct crypto_aes_ctx ctx;\n+\tstruct aes_enckey aes;\n \tint ret;\n \n-\tret = aes_expandkey(&ctx, key, key_len);\n+\tret = aes_prepareenckey(&aes, key, key_len);\n \tif (ret)\n \t\treturn ret;\n \n-\taes_encrypt(&ctx, hkey, input);\n-\tmemzero_explicit(&ctx, sizeof(ctx));\n+\taes_encrypt(&aes, hkey, input);\n+\tmemzero_explicit(&aes, sizeof(aes));\n \treturn 0;\n }\n \n static int vsc8584_macsec_transformation(struct phy_device *phydev,\n \t\t\t\t\t struct macsec_flow *flow,\n", "prefixes": [ "v2", "21/35" ] }
