Build / portability:
- Drop #pragma message in fwtpm_crypto.c (MSVC-incompatible)
- Replace non-ASCII section sign with Sec. across all sources/docs
Configure:
- Add --enable-pqc alias for --enable-v185 (same WOLFTPM_V185 macro)
- Auto-detect: when --enable-fwtpm + wolfCrypt has dilithium.h+mlkem.h
and neither flag is set, configure auto-enables PQC; --disable-pqc
opts out
- Both flags probe the wolfSSL PQC headers and fail at configure time
with a clear hint when missing
Spec / security hardening:
- VerifySequenceComplete now emits TPM_ST_DIGEST_VERIFIED (with hashAlg
metadata) for Hash-ML-DSA tickets, MESSAGE_VERIFIED for Pure ML-DSA
(was mis-tagging digests as messages, breaking PolicyTicket consumers)
- Sign/VerifySequenceComplete: free the slot on TPM_RC_SIGN_CONTEXT_KEY
too, so wrong-key Complete cannot exhaust FWTPM_MAX_SIGN_SEQ slots
(CWE-772 DoS)
- TestParms PQC arms return TPM_RC_PARMS (spec-correct) instead of
TPM_RC_VALUE; reject MLDSA/MLKEM parameter sets not actually compiled
in; parse TPMS_MLKEM_PARMS.symmetric via TPM2_Packet_ParseSymmetric
- GetCapability TPMA_ML_PARAMETER_SETS gates each MLDSA/MLKEM bit on the
per-set wolfCrypt availability macro (subset builds advertise truth)
- TPM2_VerifySignature client parser now defensive: only consume the
v1.85 metaAlg when tag==DIGEST_VERIFIED && hierarchy!=RH_NULL
- VerifyDigestSignature: hard-fail on keyName overflow instead of
silently emitting a ticket missing the name binding
- TPM_GENERATED_VALUE prefix check guarded with rc==0
- Drop dead (void)cmdSize casts in Sign/VerifySequenceStart
- wolfTPM2_EncryptSecret_MLKEM: track wc_InitRng_ex/wc_MlKemKey_Init
success flags so Free is only called on initialized state
- UBSan-v185 sanitizer cflags: explicitly disable signed-integer-overflow
and shift checks (matches the comment about wolfSSL Hash_df 440<<24)
Embedded RAM:
- FWTPM_NV_PUBAREA_EST derives from FWTPM_MAX_MLDSA_PUB_SIZE /
FWTPM_MAX_MLKEM_PUB_SIZE auto-shrink macros (subset builds save NV)
- tpm2_types.h MAX_MLDSA_*/MAX_MLKEM_* stay at worst-case (ABI floor
for TPM2B wire buffers) with comment
Tests:
- Negative test for Hash-MLDSA VerifySeqComplete ticket tag
- Negative test exposing sign-seq slot leak on TPM_RC_SIGN_CONTEXT_KEY
- Roundtrip test for wolfTPM2_SignDigest + VerifyDigestSignature
Documentation:
- README, FWTPM.md, fwtpm/README.md, examples/pqc/README.md mention
both --enable-pqc and --enable-v185 + auto-detect
- README wolfSSL line: --enable-pkcallbacks + WC_RSA_NO_PADDING
- fwtpm/README.md: drop FWTPM_SPEC_* labels (macros never existed),
remove v1.85 Additions table (all 8 commands implemented), update
coverage table to 137/113/24 (82%); note remaining gaps are
inherited v1.59/v1.84 commands, not PQC
- fwtpm_nv.h:52: clarify 2592 vs 2720 math (PQC pub key + header slack)
