2021-03-07crypto: qce - Remove totallen and offset in qce_startThara Gopinath
totallen is used to get the size of the data to be transformed. This is also available via nbytes or cryptlen in the qce_sha_reqctx and qce_cipher_ctx. Similarly offset convey nothing for the supported encryption and authentication transformations and is always 0. Remove these two redundant parameters in qce_start.

2021-03-07crypto: qce - Hold back a block of data to be transferred as part of finalThara Gopinath
If the available data to transfer is exactly a multiple of block size, save the last block to be transferred in qce_ahash_final (with the last block bit set) if this is indeed the end of data stream. If not this saved block will be transferred as part of next update. If this block is not held back and if this is indeed the end of data stream, the digest obtained will be wrong since qce_ahash_final will see that rctx->buflen is 0 and return doing nothing which in turn means that a digest will not be copied to the destination result buffer. qce_ahash_final cannot be made to alter this behavior and allowed to proceed if rctx->buflen is 0 because the crypto engine BAM does not allow for zero length transfers.

2021-03-07crypto: qce - Restore/save ahash state with custom struct in export/importThara Gopinath
Export and import interfaces save and restore partial transformation states. The partial states were being stored and restored in struct sha1_state for sha1/hmac(sha1) transformations and sha256_state for sha256/hmac(sha256) transformations.This led to a bunch of corner cases where improper state was being stored and restored. A few of the corner cases that turned up during testing are: - wrong byte_count restored if export/import is called twice without h/w transaction in between - wrong buflen restored back if the pending buffer length is exactly the block size. - wrong state restored if buffer length is 0. To fix these issues, save and restore the partial transformation state using the newly introduced qce_sha_saved_state struct. This ensures that all the pieces required to properly restart the transformation is captured and restored back Signed-off-by: Thara Gopinath <thara.gopinath@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2021-03-02vio: make remove callback return voidUwe Kleine-König
The driver core ignores the return value of struct bus_type::remove() because there is only little that can be done. To simplify the quest to make this function return void, let struct vio_driver::remove() return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea. Note there are two nominally different implementations for a vio bus: one in arch/sparc/kernel/vio.c and the other in arch/powerpc/platforms/pseries/vio.c. This patch only adapts the powerpc one. Before this patch for a device that was bound to a driver without a remove callback vio_cmo_bus_remove(viodev) wasn't called. As the device core still considers the device unbound after vio_bus_remove() returns calling this unconditionally is the consistent behaviour which is implemented here.

It tries to select the MBOX Kconfig option but that option itself depends on many other options which are not selected, e.g., CONFIG_NET_VENDOR_MARVELL. It would be inappropriate to select them all as randomly prompting the user for network options which would oterhwise be disabled just because a crypto driver has been enabled makes no sense. This patch fixes this by adding a dependency on NET_VENDOR_MARVELL. This makes the crypto driver invisible if the network option is off. If the crypto driver must be visible even without the network stack then the shared mbox code should be moved out of drivers/net.

2021-02-04KVM/SVM: add support for SEV attestation commandBrijesh Singh
The SEV FW version >= 0.23 added a new command that can be used to query the attestation report containing the SHA-256 digest of the guest memory encrypted through the KVM_SEV_LAUNCH_UPDATE_{DATA, VMSA} commands and sign the report with the Platform Endorsement Key (PEK). See the SEV FW API spec section 6.8 for more details. Note there already exist a command (KVM_SEV_LAUNCH_MEASURE) that can be used to get the SHA-256 digest. The main difference between the KVM_SEV_LAUNCH_MEASURE and KVM_SEV_ATTESTATION_REPORT is that the latter can be called while the guest is running and the measurement value is signed with PEK.

2021-01-29crypto: talitos - Work around SEC6 ERRATA (AES-CTR mode data size error)Christophe Leroy
Talitos Security Engine AESU considers any input data size that is not a multiple of 16 bytes to be an error. This is not a problem in general, except for Counter mode that is a stream cipher and can have an input of any size. Test Manager for ctr(aes) fails on 4th test vector which has a length of 499 while all previous vectors which have a 16 bytes multiple length succeed. As suggested by Freescale, round up the input data length to the nearest 16 bytes.

2021-01-22crypto: keembay - use 64-bit arithmetic for computing bit_lenOvidiu Panait
src_size and aad_size are defined as u32, so the following expressions are currently being evaluated using 32-bit arithmetic: bit_len = src_size * 8; ... bit_len = aad_size * 8; However, bit_len is used afterwards in a context that expects a valid 64-bit value (the lower and upper 32-bit words of bit_len are extracted and written to hw). In order to make sure the correct bit length is generated and the 32-bit multiplication does not wrap around, cast src_size and aad_size to u64.

CPT offload module utilises the linux crypto framework to offload crypto processing. This patch registers supported algorithms by calling registration functions provided by the kernel crypto API. The module currently supports: - AES block cipher in CBC,ECB and XTS mode. - 3DES block cipher in CBC and ECB mode. - AEAD algorithms. authenc(hmac(sha1),cbc(aes)), authenc(hmac(sha256),cbc(aes)), authenc(hmac(sha384),cbc(aes)), authenc(hmac(sha512),cbc(aes)), authenc(hmac(sha1),ecb(cipher_null)), authenc(hmac(sha256),ecb(cipher_null)), authenc(hmac(sha384),ecb(cipher_null)), authenc(hmac(sha512),ecb(cipher_null)), rfc4106(gcm(aes)).
