Overview ======== Decouple TPM driver features relevant for Trenchboot and make tpm-buf robust and decoupled entity from the rest of driver. By doing this, code can be easily linked to the early boot code.
Goals and scope =============== This patch set contains only changes, which are acceptable to mainline driver without existence Trenchboot feature. At the same the primary goal of the included is to make driver code robust enough to meet Trenchboot's requirements. These constraints should define a meaningful DoD for this patch set. v4: - PCR patch has been removed because it does not fly without Trenchboot context. v3: - I think 6.19 is a better goal for this and thus expanded the series to be a generic Trenchboot enablers series. This version also consolidates my two separate ongoing series. v2: - While including fixes from v1, this patch set has a refocus in order to do minimal changes to make code base more compatible Trenchboot. Jarkko Sakkinen (9): tpm: Cap the number of PCR banks tpm: Use -EPERM as fallback error code in tpm_ret_to_err KEYS: trusted: Use tpm_ret_to_err() in trusted_tpm2 tpm2-sessions: Remove 'attributes' from tpm_buf_append_auth tpm2-sessions: Unmask tpm_buf_append_hmac_session() KEYS: trusted: Open code tpm2_buf_append() tpm-buf: check for corruption in tpm_buf_append_handle() tpm-buf: Remove chip parameter from tpm_buf_append_handle tpm-buf: Enable managed and stack allocations. drivers/char/tpm/tpm-buf.c | 141 ++++++---- drivers/char/tpm/tpm-chip.c | 13 +- drivers/char/tpm/tpm-sysfs.c | 21 +- drivers/char/tpm/tpm.h | 2 - drivers/char/tpm/tpm1-cmd.c | 185 +++++-------- drivers/char/tpm/tpm2-cmd.c | 313 ++++++++++------------ drivers/char/tpm/tpm2-sessions.c | 129 +++++---- drivers/char/tpm/tpm2-space.c | 44 ++- drivers/char/tpm/tpm_vtpm_proxy.c | 30 +-- include/linux/tpm.h | 65 ++--- security/keys/trusted-keys/trusted_tpm1.c | 34 ++- security/keys/trusted-keys/trusted_tpm2.c | 237 +++++++--------- 12 files changed, 542 insertions(+), 672 deletions(-) -- 2.39.5
