For glue code that's used by Zinc, the actual Crypto API functions might not necessarily exist, and don't need to exist either. Before this patch, there are valid build configurations that lead to a unbuildable kernel. This fixes it to conditionalize those symbols on the existence of the proper config entry. Signed-off-by:

In the vmx crypto Makefile we assign to a variable called TARGET and pass that to the aesp8-ppc.pl and ghashp8-ppc.pl scripts. The variable is meant to describe what flavour of powerpc we're building for, eg. either 32 or 64-bit, and big or little endian. Unfortunately TARGET is a fairly common name for a make variable, and if it happens that TARGET is specified as a command line parameter to make, the value specified on the command line will override our value. In particular this can happen if the kernel Makefile is driven by an external Makefile that uses TARGET for something. This leads to weird build failures, eg: nonsense at /build/linux/drivers/crypto/vmx/ghashp8-ppc.pl line 45. /linux/drivers/crypto/vmx/Makefile:20: recipe for target 'drivers/crypto/vmx/ghashp8-ppc.S' failed Which shows that we passed an empty value for $(TARGET) to the perl script, confirmed with make V=1: perl /linux/drivers/crypto/vmx/ghashp8-ppc.pl > drivers/crypto/vmx/ghashp8-ppc.S We can avoid this confusion by using override, to tell make that we don't want anything to override our variable, even a value specified on the command line. We can also use a less common name, given the script calls it "flavour", let's use that. Signed-off-by:

In case of in-place decryption, the "lastc" buffer is used to copy the last ciphertext block before the decryption of the message. It is later used to update the req->iv of the skcipher_request. "lastc" variable is not used to interact with the hardware, there is no restriction to be of type "u32". Change the type of "lastc" to "u8". Signed-off-by:

The req->iv of the skcipher_request is expected to contain the last ciphertext block when the {en,de}crypt operation is done. In case of in-place decryption, copy the ciphertext in an intermediate buffer before decryption. This fixes the following tcrypt tests: alg: skcipher: atmel-cbc-des encryption test failed (wrong output IV) on test vector 0, cfg="in-place" 00000000: fe dc ba 98 76 54 32 10 alg: skcipher: atmel-cbc-tdes encryption test failed (wrong output IV) on test vector 0, cfg="in-place" 00000000: 7d 33 88 93 0f 93 b2 42 Signed-off-by: -

Currently, there is no privilege separation of the SEV command; you can run them all or none of them. This is less than ideal because it means that a compromise of the code which launches VMs could make permanent change to the SEV certifcate chain which will affect others. These commands are required to attest the VM environment: - SEV_PDH_CERT_EXPORT - SEV_PLATFORM_STATUS - SEV_GET_{ID,ID2} These commands manage the SEV certificate chain: - SEV_PEK_CERR_IMPORT - SEV_FACTORY_RESET - SEV_PEK_GEN - SEV_PEK_CSR - SEV_PDH_GEN Lets add the CAP_SYS_ADMIN check for the group of the commands which alters the SEV certificate chain to provide some level of privilege separation.

The keyed init writes the key bytes to the input buffer and does an update. We can do that in two ways: fill the buffer and update immediatelly. This is what current blake2b_init_key does. Any other following _update or _final will continue from the updated state. The other way is to write the key and set the number of bytes to process at the next _update or _final, lazy evaluation. Which leads to the the simplified code in this patch. Signed-off-by:

David Sterba authored
The call chain from blake2b_init can be simplified because the param block is effectively zeros, besides the key. - blake2b_init0 zeroes state and sets IV - blake2b_init sets up param block with defaults (key and some 1s) - init with key, write it to the input buffer and recalculate state So the compact way is to zero out the state and initialize index 0 of the state directly with the non-zero values and the key.

Commit 7a7ffe65 ("crypto: skcipher - Add top-level skcipher interface") dated 20 august 2015 introduced the new skcipher API which is supposed to replace both blkcipher and ablkcipher. While all consumers of the API have been converted long ago, some producers of the ablkcipher remain, forcing us to keep the ablkcipher support routines alive, along with the matching code to expose [a]blkciphers via the skcipher API. So switch this driver to the skcipher API, allowing us to finally drop the ablkcipher code in the near future. Co-developed-by:
