A unipolar no_std TPM 2.0 implementation that does not require heap allocator and has zero dependencies.
tpm-protocol@lists.linux.dev.Signed-off-by trailer.The list can be subscribed by sending an empty message to tpm-protocol+subscribe@lists.linux.dev, Unsubscribing follows the same exact pattern except that the subaddress is +unsubscribe. With that all out of the way it is good to remark that the process is relaxed in the sense that opening a thread in the list, or submitting a patch does not require a subscription.
As already denoted in the previous section, patches and other messages can be posted to tpm-protocol@lists.linux.dev. The mailing list archive is available at https://lore.kernel.org/tpm-protocol/.
NOTE: emails must be in text/plain. format. Emails in any other format, e.g. text/html, will be automatically discarded by the list server, and they won't appear in the mailing list.
The project provides a Makefile with make test target. The unit test is by design compiling with GNU make and rustc, and it outputs kselftest compatible exit codes. This ensures that is code that can be imported to Linux kernel.
tpm2_protocol is a low-level and policy-free library for TPM 2.0 command and response building and parsing.
The primary design goal is to be correct against TCG specifications, and to be usable in constrained environments.
The correctness is validated to the point that no rules will be introduced that could be considered as policy. In particular the number of sessions is limited against MAX_SESSIONS but not against number of allowed sessions specified for a particular command.
The tpm2-protocol library is licensed under the permissive MIT OR Apache-2.0 license to allow for wide adoption.
