David Tolnay c49ef3e03b tpm: Add tpm2-sys crate ... This CL adds a tpm2-sys crate that builds libtpm2 from source (from a git submodule) using the existing Makefile and then links the generated static library as -ltpm2. For production builds there is a flag `RUSTFLAGS='--cfg hermetic'` to disallow building our own libtpm2. Instead it will expect to find libtpm2 installed in the standard system location. Building from the libtpm2 submodule is a convenience only intended for developer environments. The functions exposed by tpm2-sys are the ones that will be necessary to initialize a TPM simulator in crosvm and execute TPM commands. Trunks uses the same functions for its simulator mode here: e4cf13c057/trunks/tpm_simulator_handle.cc Tested by running: fn main() { unsafe { tpm2_sys::TPM_Manufacture(1); } } inside cros_sdk. Libtpm2 cannot be built outside of cros_sdk because it requires openssl 1.0.2p, whereas dev machines come with openssl 1.1.0j. I have not yet added any dependency on tpm2-sys from crosvm, but when it does get added it will be behind a tpm feature flag so that crosvm can continue to build outside of cros_sdk just without tpm support. I published num_cpus version 1.9.0 to chromeos-localmirror.
