Hi, has anybody successfully used the TPM Emulator[1] module with L4Linux?
I have been trying using it with TrouSerS[2] but fail on starting tcsd with the following two errors (always one of them but never both at the same time):
gentoo-l4 TDDL[4480]: tddl.c:105 Calling write to driver gentoo-l4 tpm_emulator tpm_emulator-0.4/./linux_module.c:113: Debug: tpm_ioctl(21505, 0808e500) gentoo-l4 tpm_emulator tpm_emulator-0.4/tpm/tpm_cmd_handler.c:4156: Debug: tpm_handle_command() gentoo-l4 tpm_emulator tpm_emulator-0.4/tpm/tpm_cmd_handler.c:3473: Info: The tag value sent to for a command (0x6564) is invalid gentoo-l4 TCS[4480]: tcs_utils.c:260 ERROR: TCS GetCapability failed with result = 0x1e
and
gentoo-l4 TDDL[4483]: tddl.c:105 Calling write to driver gentoo-l4 tpm_emulator tpm_emulator-0.4/./linux_module.c:113: Debug: tpm_ioctl(21505, 0808e500) gentoo-l4 tpm_emulator tpm_emulator-0.4/tpm/tpm_cmd_handler.c:4156: Debug: tpm_handle_command() gentoo-l4 tpm_emulator tpm_emulator-0.4/tpm/tpm_cmd_handler.c:4160: Error: tpm_unmarshal_TPM_REQUEST() failed gentoo-l4 TDDL[4483]: tddl.c:148 ERROR: Zero bytes read from device /dev/tpm gentoo-l4 TCS[4483]: tcs_utils.c:260 ERROR: TCS GetCapability failed with result = 0x1087
I guess that something is going wrong with the call to ioctl from tddl but wasn't able to figure it out yet.
Are there modifications necessary for using modules with L4Linux?
