Hello,
The Texas Instruments keystone2 out-of-tree kernel uses the private_AES_set_encrypt_key() and
the AES_encrypt() at the crypto HW acceleration driver.
The "crypto: arm/aes - replace bit-sliced OpenSSL NEON code" commit removed those functions.
Here is a code, which calls the removed functions.
static inline int sa_aes_xcbc_subkey(u8 *sub_key1, u8 *sub_key2,
u8 *sub_key3, const u8 *key,
u16 key_sz)
{
struct AES_KEY enc_key;
if (private_AES_set_encrypt_key(key, (key_sz * 8), &enc_key)) {
pr_err("%s: failed to set enc key\n", __func__);
return -EINVAL;
}
if (sub_key1) {
memset(sub_key1, 0x01, AES_BLOCK_SIZE);
AES_encrypt(sub_key1, sub_key1, &enc_key);
}
if (sub_key2) {
memset(sub_key2, 0x02, AES_BLOCK_SIZE);
AES_encrypt(sub_key2, sub_key2, &enc_key);
}
if (sub_key3) {
memset(sub_key3, 0x03, AES_BLOCK_SIZE);
AES_encrypt(sub_key3, sub_key3, &enc_key);
}
return 0;
}
Which functions can I use to replace the removed ones in the above code?
I'm very appreciate any advice.
Sincerely,
-Vitaly Andrianov
