[4.0.0] - 2023-01-02

Fixed

• tcti-ldr: Use heap instead of stack when tcti initialize
• Fix usage of NULL pointer if Esys_TR_SetAuth is calles with ESYS_TR_NONE.
• Conditionally check user/group manipulation commands.
• Store VERSION into the release tarball.
• When using DESTDIR for make einstall, do not invoke systemd-sysusers and systemd-tmpfiles.
• esys_iutil: fix possible NPD.
• Tss2_Sys_Flushcontext: flushHandle was encoded as a handleArea handle and not as parameter one, this affected the contents of cpHash.
• esys: fix allow usage of HMAC sessions for Esys_TR_FromTPMPublic.
• fapi: fix usage of policy_nv with a TPM nv index.
• linking tcti for libtpms against tss2-tctildr. It should be linked against tss2-mu.
• build: Remove erroneous trailing comma in linker option. Bug #2391.
• fapi: fix encoding of complex tpm2bs in authorize nv, duplication select and policy template policies. Now the complex and TPMT or TPMS representations can be used. Bug #2383
• The error message for unsupported FAPI curves was in hex without a leading 0x, make it integer output to clarify.
• Documentation that had various scalar out pointers as "callee allocated".
• test: build with opaque FILE structure like in musl libc.
• Transient endorsement keys were not recreated according to the EK credential profile.
• Evict control for a persistent EK failed during provisioning if an auth value for the storage hierarchy was set.
• The authorization of the storage hierarchy is now added. Fixes FAPI: Provisioning error if an auth value is needed for the
  storage hierarchy #2438.
• Usage of a second profile in a path was not possible because the default profile was always used.
• The setting of an empty auth value for Fapi_Provision was fixed.
• JSON encoding of a structure TPMS_POLICYAUTHORIZATION used the field keyPEMhashAlg instead of hashAlg as
  defined in "TCG TSS 2.0 JSON Data Types and Policy Language Specification". Rename to hashAlg but preserve support
  for reading keyPEMhashAlg for backwards compatibility.
• fapi: PolicySecret did not work with keys as secret object.
• Esys_PCR_SetAuthValue: remembers the auth like other SetAutg ESAPI functions.
• tests: esys-pcr-auth-value.int moved to destructive tests.
• FAPI: Fix double free if keystore is corrupted.
• Marshaling of TPMU_CAPABILITIES data, only field intelPttProperty was broken before.a
• Spec deviation in Fapi_GetDescription caused description to be NULL when it should be empty string.
  This is API breaking but considered a bug since it deviated from the FAPI spec.
• FAPI: undefined reference to curl_url_strerror when using curl less than 7.80.0.
• FAPI: Fixed support for EK templates in NV inidices per the spec, see #2518 for details.
• FAPI: fix NPD in ifapi_curl logging.
• FAPI: Improve documentation fapi-profile
• FAPI: Fix CURL HTTP handling.
• FAPI: Return FAPI_RC_IO_ERROR if a policy does not exist in keystore.

Added

• TPM version 1.59 support.
• ci: ubuntu-22.04 added.
• mbedTLS 3.0 is supported by ESAPI.
• Add CreationHash to JSON output for usage between applications not using the FAPI keystore, like command line tools.
• Reduced code size for SAPI.
• Support for Runtime Switchable ESAPI Crypto Backend via Esys_SetCryptoCallbacks.
• Testing for TCG EK Credential Profile TPM 2.0, Version 2.4 Rev. 3, 2021 for the low and high address range of EK templates.
• tss2-rc: Tss2_RC_DecodeInfo function for parsing TSS2_RC into the various bit fields.
• FAPI support for P_ECC384 profile.
• tss2-rc: Tss2_RC_DecodeInfoError: Function to get a human readable error from a TSS2_RC_INFO returned by
  Tss2_RC_DecodeInfo
• tcti: Generic SPI driver, implementors only need to connect to acquire/release, transmit/receive, and sleep/timeout functions.
• FAPI: Add event logging for Firmware and IMA Events. See #2170 for details.
• FAPI: Fix Fapi_ChangeAuth updates on hierarchy objects not being reflected across profiles.
• FAPI: Allow keyedhash keys in PolicySigned.
• ESAPI: Support sha512 for mbedtls crypto backend.
• TPM2B_MAX_CAP_BUFFER and mu routines
• vendor field to TPMU_CAPABILTIIES
• FAPI: support for PolicyTemplate

Changed

• libmu soname from 0:0:0 to 0:1:0.
• tss2-sys soname from 1:0:0 to 1:1:0
• tss2-esys: from 0:0:0 to 0:1:0
• FAPI ignores vendor properties on Fapi_GetInfo
• FAPI Event Logging JSON format, See #2170 for details.

Removed

• Dead struct TPMS_ALGORITHM_DESCRIPTION
• Dead field intelPttProperty from TPMU_CAPABILITIES
• Dead code Tss2_MU_TPMS_ALGORITHM_DESCRIPTION_Marshal
• Dead code Tss2_MU_TPMS_ALGORITHM_DESCRIPTION_Unmarshal
