<torvalds@linux-foundation.org> # Date: Thu Nov 1 15:23:59 2018 -0700 # # Merge branch 'next-keys2' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security # # Pull keys updates from James Morris: # "Provide five new operations in the key_type struct that can be used to # provide access to asymmetric key operations. These will be implemented # for the asymmetric key type in a later patch and may refer to a key # retained in RAM by the kernel or a key retained in crypto hardware. # # int (asym_query)(const struct kernel_pkey_params params, # struct kernel_pkey_query info); # int (asym_eds_op)(struct kernel_pkey_params params, # const void in, void out); # int (asym_verify_signature)(struct kernel_pkey_params params, # const void in, const void in2); # # Since encrypt, decrypt and sign are identical in their interfaces, # they're rolled together in the asym_eds_op() operation and there's an # operation ID in the params argument to distinguish them. # # Verify is different in that we supply the data and the signature # instead and get an error value (or 0) as the only result on the # expectation that this may well be how a hardware crypto device may # work" # # 'next-keys2' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (22 commits) # KEYS: asym_tpm: Add support for the
