crypto: skcipher - rename the crypto_blkcipher module and kconfig option

2019-11-01T05:42:47+00:00

Now that the blkcipher algorithm type has been removed in favor of skcipher, rename the crypto_blkcipher kernel module to crypto_skcipher, and rename the config options accordingly: CONFIG_CRYPTO_BLKCIPHER => CONFIG_CRYPTO_SKCIPHER CONFIG_CRYPTO_BLKCIPHER2 => CONFIG_CRYPTO_SKCIPHER2 Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: ccp - Make CCP debugfs support optional

2019-07-26T12:08:03+00:00

Add a config option to exclude DebugFS support in the CCP driver. Signed-off-by: Gary R Hook Signed-off-by: Herbert Xu

crypto: ccp - move to AES library for CMAC key derivation

2019-07-26T04:58:13+00:00

Use the AES library instead of the cipher interface to perform the single block of AES processing involved in updating the key of the cmac(aes) hash. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

treewide: Add SPDX license identifier - Makefile/Kconfig

crypto: ccp: Add Platform Security Processor (PSP) device support

2017-12-04T16:57:28+00:00

The Platform Security Processor (PSP) is part of the AMD Secure Processor (AMD-SP) functionality. The PSP is a dedicated processor that provides support for key management commands in Secure Encrypted Virtualization (SEV) mode, along with software-based Trusted Execution Environment (TEE) to enable third-party trusted applications. Note that the key management functionality provided by the SEV firmware can be used outside of the kvm-amd driver hence it doesn't need to depend on CONFIG_KVM_AMD.

crypto: ccp: Build the AMD secure processor driver only with AMD CPU support

2017-12-04T16:57:26+00:00

This is AMD-specific hardware so present it in Kconfig only when AMD CPU support is enabled or on ARM64 where it is also used.

crypto: ccp - select CONFIG_CRYPTO_RSA

2017-08-09T12:17:59+00:00

Without the base RSA code, we run into a link error: ERROR: "rsa_parse_pub_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined! ERROR: "rsa_parse_priv_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined! Like the other drivers implementing RSA in hardware, this can be avoided by always enabling the base support when we build CCP.

crypto: ccp - Introduce the AMD Secure Processor device

2017-07-18T09:51:19+00:00

The CCP device is part of the AMD Secure Processor. In order to expand the usage of the AMD Secure Processor, create a framework that allows functional components of the AMD Secure Processor to be initialized and handled appropriately.

crypto: ccp - Register the CCP as a DMA resource

2016-04-20T09:50:06+00:00

The CCP has the ability to provide DMA services to the kernel using pass-through mode of the device. Register these services as general purpose DMA channels.
