A new file is added tpm1-cmd.c that contains tpm 1.x specific commands. In addition, tpm 1.x commands are now implemented using tpm_buf structure and instead of tpm_cmd_t construct. The latter is now removed. Note: my tpm 1.x HW availability is limited hence some more testing is needed. This series also contains two trivial cleanups and addition of new commands by TCG spec 1.36, now supported on new Intet's platforms. Tomas Winkler (21): tpm2: add new tpm2 commands according to TCG 1.36 tpm: sort objects in the Makefile tpm: factor out tpm 1.x duration calculation to tpm1-cmd.c tpm: add tpm_calc_ordinal_duration() wrapper tpm: factor out tpm_get_timeouts() tpm: move tpm1_pcr_extend to tpm1-cmd.c tpm: move tpm_getcap to tpm1-cmd.c tpm: factor out tpm1_get_random into tpm1-cmd.c tpm: move tpm 1.x selftest code from tpm-interface.c tpm1-cmd.c tpm: factor out tpm 1.x pm suspend flow into tpm1-cmd.c tpm: factor out tpm_startup function tpm: move pcr extend code to tpm2-cmd.c tpm: add tpm_auto_startup() into tpm-interface.c tpm: tpm-interface.c drop unused macros tpm: tpm-space.c remove unneeded semicolon tpm: tpm1: rewrite tpm1_get_random() using tpm_buf structure tpm1: implement tpm1_pcr_read_dev() using tpm_buf structure tmp1: rename tpm1_pcr_read_dev to tpm1_pcr_read(). tpm1: reimplement SAVESTATE using tpm_buf tpm1: reimplement tpm1_continue_selftest() using tpm_buf tpm: use u32 instead of int for PCR index drivers/char/tpm/Makefile | 16 +- drivers/char/tpm/st33zp24/st33zp24.c | 2 +- drivers/char/tpm/tpm-chip.c | 11 +- drivers/char/tpm/tpm-interface.c | 841 +++-------------------------------- drivers/char/tpm/tpm-sysfs.c | 52 +-- drivers/char/tpm/tpm.h | 98 ++-- drivers/char/tpm/tpm1-cmd.c | 781 ++++++++++++++++++++++++++++++++ drivers/char/tpm/tpm2-cmd.c | 339 +++++++------- drivers/char/tpm/tpm2-space.c | 2 +- drivers/char/tpm/tpm_i2c_nuvoton.c | 10 +- drivers/char/tpm/tpm_tis_core.c | 10 +- include/linux/tpm.h | 11 +- security/integrity/ima/ima_crypto.c | 5 +- 13 files changed, 1117 insertions(+), 1061 deletions(-) create mode 100644 drivers/char/tpm/tpm1-cmd.c
