Eric Biggers	40b9969796	crypto: testmgr - replace CRYPTO_MANAGER_DISABLE_TESTS with CRYPTO_SELFTESTS ... The negative-sense of CRYPTO_MANAGER_DISABLE_TESTS is a longstanding mistake that regularly causes confusion. Especially bad is that you can have CRYPTO=n && CRYPTO_MANAGER_DISABLE_TESTS=n, which is ambiguous. Replace CRYPTO_MANAGER_DISABLE_TESTS with CRYPTO_SELFTESTS which has the expected behavior. The tests continue to be disabled by default. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>	2025-05-12 13:33:14 +08:00
Ard Biesheuvel	f135440447	crypto: lib - implement library version of AES in CFB mode ... Implement AES in CFB mode using the existing, mostly constant-time generic AES library implementation. This will be used by the TPM code to encrypt communications with TPM hardware, which is often a discrete component connected using sniffable wires or traces. While a CFB template does exist, using a skcipher is a major pain for non-performance critical synchronous crypto where the algorithm is known at compile time and the data is in contiguous buffers with valid kernel virtual addresses.
