ld: drivers/crypto/sa2ul.o: in function `sa_sha_digest': sa2ul.c:(.text+0x1faf): undefined reference to `sha512_zero_message_hash'
sa2ul.c uses sha512_zero_message_hash, sha1_zero_message_hash, and sha256_zero_message_hash, but it does not 'select' any of the Kconfig symbols that cause those hashes to be present.
Should it select the needed Kconfig symbols or should it use #ifdef blocks as needed?
like so:
static int zero_message_process(struct ahash_request *req) { struct crypto_ahash *tfm = crypto_ahash_reqtfm(req); int sa_digest_size = crypto_ahash_digestsize(tfm);
switch (sa_digest_size) { #ifdef CONFIG_CRYPTO_SHA1 case SHA1_DIGEST_SIZE: memcpy(req->result, sha1_zero_message_hash, sa_digest_size); break; #endif #ifdef CONFIG_CRYPTO_SHA256 case SHA256_DIGEST_SIZE: memcpy(req->result, sha256_zero_message_hash, sa_digest_size); break; #endif #ifdef CONFIG_CRYPTO_SHA512 case SHA512_DIGEST_SIZE: memcpy(req->result, sha512_zero_message_hash, sa_digest_size); break; #endif default: return -EINVAL; }
return 0; }
