Hi, New features: 1. ARM TEE backend for kernel trusted keys to complete the existing TPM backend. 2. ASN.1 format for TPM2 trusted keys to make them interact with the user space stack, such as OpenConnect VPN. Other than that, contains bunch of bug fixes. /Jarkko The following changes since commit 50987beca096a7ed4f453a6da245fd6a2fadedeb: Merge tag 'trace-v5.12-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace (2021-04-13 18:40:00 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd.git/ tags/tpmdd-next-v5.13 for you to fetch changes up to aec00aa04b1131e17e6744681b380779f89d77b3: KEYS: trusted: Fix missing null return from kzalloc call (2021-04-14 16:30:31 +0300) ---------------------------------------------------------------- tpmdd updates for Linux v5.13 ---------------------------------------------------------------- Colin Ian King (1): KEYS: trusted: Fix missing null return from kzalloc call James Bottomley (5): 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: Make sealed key properly interoperable Stefan Berger (3): tpm: efi: Use local variable for calculating final log size tpm: acpi: Check eventlog signature before using it tpm: vtpm_proxy: Avoid reading host log when using a virtual device Sumit Garg (4): KEYS: trusted: Add generic trusted keys framework KEYS: trusted: Introduce TEE based Trusted Keys doc: trusted-encrypted: updates with TEE as a new trust source MAINTAINERS: Add entry for TEE based Trusted Keys Zhihao Cheng (1): char: tpm: fix error return code in tpm_cr50_i2c_tis_recv() Documentation/admin-guide/kernel-parameters.txt | 12 + Documentation/security/keys/trusted-encrypted.rst | 229 +++++++++-- MAINTAINERS | 8 + drivers/char/tpm/eventlog/acpi.c | 33 +- drivers/char/tpm/eventlog/common.c | 3 + drivers/char/tpm/eventlog/efi.c | 29 +- drivers/char/tpm/tpm_tis_i2c_cr50.c | 1 + include/keys/trusted-type.h | 55 +++ include/keys/trusted_tee.h | 16 + include/keys/trusted_tpm.h | 29 +- include/linux/asn1_encoder.h | 32 ++ include/linux/oid_registry.h | 5 + include/linux/tpm.h | 2 + lib/Kconfig | 3 + lib/Makefile | 1 + lib/asn1_encoder.c | 454 ++++++++++++++++++++++ security/keys/Kconfig | 3 + security/keys/trusted-keys/Makefile | 6 + security/keys/trusted-keys/tpm2key.asn1 | 11 + security/keys/trusted-keys/trusted_core.c | 360 +++++++++++++++++ security/keys/trusted-keys/trusted_tee.c | 318 +++++++++++++++ security/keys/trusted-keys/trusted_tpm1.c | 398 +++++-------------- security/keys/trusted-keys/trusted_tpm2.c | 269 +++++++++++-- 23 files changed, 1887 insertions(+), 390 deletions(-) create mode 100644 include/keys/trusted_tee.h create mode 100644 include/linux/asn1_encoder.h create mode 100644 lib/asn1_encoder.c create mode 100644 security/keys/trusted-keys/tpm2key.asn1 create mode 100644 security/keys/trusted-keys/trusted_core.c create mode 100644 security/keys/trusted-keys/trusted_tee.c
