Make the changes that are needed to detach TPM space code from tpm_transmit() flow so that we do no longer need nested tpm_transmit() calls. v2: * Print tpm2_commit_space() error inside tpm2_commit_space() * Error code was not printed when recv() callback failed. It is fixed in this version. * Added a patch that removes @space from tpm_transmit(). * Fixed a regression in earlier series. Forgot to amend the change from the staging area that renames NESTED to UNLOCKED in tpm2-space.c. Jarkko Sakkinen (8): tpm: use tpm_buf in tpm_transmit_cmd() as the IO parameter tpm: print tpm2_commit_space() error inside tpm2_commit_space() tpm: clean up tpm_try_transmit() error handling flow tpm: access command header through struct in tpm_try_transmit() tpm: move tpm_validate_commmand() to tpm2-space.c tpm: encapsulate tpm_dev_transmit() tpm: move TPM space code out of tpm_transmit() tpm: remove @space from tpm_transmit() drivers/char/tpm/tpm-dev-common.c | 50 ++++++- drivers/char/tpm/tpm-interface.c | 240 +++++++++++------------------- drivers/char/tpm/tpm-sysfs.c | 5 +- drivers/char/tpm/tpm.h | 16 +- drivers/char/tpm/tpm1-cmd.c | 28 +--- drivers/char/tpm/tpm2-cmd.c | 39 ++--- drivers/char/tpm/tpm2-space.c | 77 +++++++--- drivers/char/tpm/tpm_vtpm_proxy.c | 3 +- 8 files changed, 220 insertions(+), 238 deletions(-) -- 2.19.1
