It also simplifies the use of policy with keys because the ASN.1 format is designed to carry a description of how to construct the policy, with the result that simple policies (like authorization and PCR locking) can now be constructed and used in the kernel, bringing the TPM 2.0 policy use into line with how TPM 1.2 works. The key format is designed to be compatible with our two openssl engine implementations as well as with the format used by openconnect. I've added seal/unseal to my engine so I can use it for interoperability testing and I'll later use this for sealed symmetric keys via engine: https://git.kernel.org/pub/scm/linux/kernel/git/jejb/openssl_tpm2_engine.git/ James --- James Bottomley (6): lib: add ASN.1 encoder oid_registry: Add TCG defined OIDS for TPM keys security: keys: trusted: fix TPM2 authorizations security: keys: trusted: use ASN.1 TPM2 key format for the blobs security: keys: trusted: add ability to specify arbitrary policy security: keys: trusted: implement counter/timer policy Documentation/security/keys/trusted-encrypted.rst | 64 ++- include/keys/trusted-type.h | 7 +- include/linux/asn1_encoder.h | 32 ++ include/linux/oid_registry.h | 5 + include/linux/tpm.h | 8 + lib/Makefile | 2 +- lib/asn1_encoder.c | 431 ++++++++++++++++++++ security/keys/Kconfig | 2 + security/keys/trusted-keys/Makefile | 2 +- security/keys/trusted-keys/tpm2-policy.c | 463 ++++++++++++++++++++++ security/keys/trusted-keys/tpm2-policy.h | 31 ++ security/keys/trusted-keys/tpm2key.asn1 | 23 ++ security/keys/trusted-keys/trusted_tpm1.c | 56 ++- security/keys/trusted-keys/trusted_tpm2.c | 370 +++++++++++++++-- 14 files changed, 1459 insertions(+), 37 deletions(-) create mode 100644 include/linux/asn1_encoder.h create mode 100644 lib/asn1_encoder.c create mode 100644 security/keys/trusted-keys/tpm2-policy.c create mode 100644 security/keys/trusted-keys/tpm2-policy.h create mode 100644 security/keys/trusted-keys/tpm2key.asn1 -- 2.16.4
