From 5a417f32f1afe0ffca7f5cbff67145a157b1589b Mon Sep 17 00:00:00 2001 From: Gary Lin <glin@suse.com> Date: Tue, 7 Feb 2023 18:31:12 +0800 Subject: [PATCH 1/4] tpm2: Add TPM2 types, structures, and command constants Add new TPM2 types and structures as the preparation to support authorized policy. * New types: TPM_ALG_ECDAA, TPM_ALG_ECDSA, TPM_ALG_ECSCHNORR, TPM_ALG_RSASSA, TPM_ALG_RSAPSS, TPM_ALG_SM2, and TPMI_ALG_SIG_SCHEME * New structures: TPMS_EMPTY, TPMS_SIGNATURE_RSA, TPMS_SIGNATURE_ECC, TPMS_SIGNATURE_ECDSA, TPMS_SIGNATURE_ECDAA, TPMS_SIGNATURE_SM2, TPMS_SIGNATURE_ECSCHNORR, TPMU_SIGNATURE, and TPMT_TK_VERIFIED * New command constants: TPM_CC_LoadExternal, TPM_CC_HashSequenceStart, TPM_CC_SequenceUpdate, TPM_CC_SequenceComplete, TPM_CC_Hash, TPM_CC_VerifySignature, TPM_CC_PolicyAuthorize Signed-off-by: Gary Lin <glin@suse.com> --- include/grub/tpm2/internal/structs.h | 86 ++++++++++++++++++++++++++++ include/grub/tpm2/internal/types.h | 42 +++++++++----- 2 files changed, 114 insertions(+), 14 deletions(-) diff --git a/include/grub/tpm2/internal/structs.h b/include/grub/tpm2/internal/structs.h index 72d71eb70..db9eb6cf6 100644 --- a/include/grub/tpm2/internal/structs.h +++ b/include/grub/tpm2/internal/structs.h @@ -672,4 +672,90 @@ struct TPMT_TK_CREATION }; typedef struct TPMT_TK_CREATION TPMT_TK_CREATION; +/* TPMS_EMPTY Structure */ +struct TPMS_EMPTY { + grub_uint8_t empty[1]; /* a structure with no member */ +}; +typedef struct TPMS_EMPTY TPMS_EMPTY; + +/* TPMS_SIGNATURE_RSA Structure */ +struct TPMS_SIGNATURE_RSA { + TPMI_ALG_HASH hash; + TPM2B_PUBLIC_KEY_RSA sig; +}; +typedef struct TPMS_SIGNATURE_RSA TPMS_SIGNATURE_RSA; + +/* Definition of Types for RSA Signature */ +typedef TPMS_SIGNATURE_RSA TPMS_SIGNATURE_RSASSA; +typedef TPMS_SIGNATURE_RSA TPMS_SIGNATURE_RSAPSS; + +/* TPMS_SIGNATURE_ECC Structure */ +struct TPMS_SIGNATURE_ECC { + TPMI_ALG_HASH hash; + TPM2B_ECC_PARAMETER signatureR; + TPM2B_ECC_PARAMETER signatureS; +}; +typedef struct TPMS_SIGNATURE_ECC TPMS_SIGNATURE_ECC; + +/* Definition of Types for ECC TPMS_SIGNATURE_ECC */ +typedef TPMS_SIGNATURE_ECC TPMS_SIGNATURE_ECDSA; +typedef TPMS_SIGNATURE_ECC TPMS_SIGNATURE_ECDAA; +typedef TPMS_SIGNATURE_ECC TPMS_SIGNATURE_SM2; +typedef TPMS_SIGNATURE_ECC TPMS_SIGNATURE_ECSCHNORR; + +/* TPMU_SIGNATURE Structure */ +union TPMU_SIGNATURE { + TPMS_SIGNATURE_RSASSA rsassa; + TPMS_SIGNATURE_RSAPSS rsapss; + TPMS_SIGNATURE_ECDSA ecdsa; + TPMS_SIGNATURE_ECDAA ecdaa; + TPMS_SIGNATURE_SM2 sm2; + TPMS_SIGNATURE_ECSCHNORR ecschnorr; + TPMT_HA hmac; + TPMS_SCHEME_HASH any; + TPMS_EMPTY null; +}; +typedef union TPMU_SIGNATURE TPMU_SIGNATURE; + +/* TPMT_SIGNATURE Structure */ +struct TPMT_SIGNATURE { + TPMI_ALG_SIG_SCHEME sigAlg; + TPMU_SIGNATURE signature; +}; +typedef struct TPMT_SIGNATURE TPMT_SIGNATURE; + +static inline TPMI_ALG_HASH +TPMT_SIGNATURE_get_hash_alg (TPMT_SIGNATURE *sig) +{ + switch (sig->sigAlg) + { + case TPM_ALG_RSASSA: + return sig->signature.rsassa.hash; + case TPM_ALG_RSAPSS: + return sig->signature.rsapss.hash; + case TPM_ALG_ECDSA: + return sig->signature.ecdsa.hash; + case TPM_ALG_ECDAA: + return sig->signature.ecdaa.hash; + case TPM_ALG_SM2: + return sig->signature.sm2.hash; + case TPM_ALG_ECSCHNORR: + return sig->signature.ecschnorr.hash; + case TPM_ALG_HMAC: + return sig->signature.hmac.hashAlg; + default: + break; + } + + return TPM_ALG_NULL; +} + +/* TPMT_TK_VERIFIED Structure */ +struct TPMT_TK_VERIFIED { + TPM_ST tag; + TPMI_RH_HIERARCHY hierarchy; + TPM2B_DIGEST digest; +}; +typedef struct TPMT_TK_VERIFIED TPMT_TK_VERIFIED; + #endif /* !
