This commit adds a hash library containing support for sha1 and sha2. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>
This commit adds the Kconfig for selecting the security hardware (secdev) framework. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>
This commit bring in the TPM driver code from tboot, commit 4a904a6, apply Xen coding style, and integrates with Xen's build. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>
Tboot, from which the code came, is only concerned for x86 systems. Typically on x86 systems, the TPM is accessed using the MMIO hardware interface for which there are two ABIs, FIFO and CRB. This commit looks to refactor the hardware interface logic to enable the ability to support other hardware interfaces, such as the Mobile TPM interface typically used on Arm. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>
The tboot environment did not have an accurate way of tracking time outs on access to the TPM hardware. As such, it relied on counting loops and using a multiplier factor to estimate amount of time a loop would take. Now that the code is under Xen, it can use the time functions to determine an accurate(ly) time out. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>
Adds secdev headers. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>
This commit adds a secdev interface callable by the secdev framework to detect the tpm and extend a commandline selectable PCR with a domain's measurements. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>
This commits move the initialization of a global primary into an commented out function. This is to reserve the logic for later use to create per domain key hierarchy. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>
Introduces the secdev framework with TPM being the first supported device. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>
This commit leverages the TPM driver to measure Dom0's kernel and initrd before the domain is contstructed. Signed-off-by: Daniel P. Smith <dpsmith@apertussolutions.com>

The secdev-driver branch is part upstreamable and part RFC. Opening PR to facilitate review. Biggest todo is the commit that adds measuring dom0. This needs to be rewritten to comply with the SLRT measurement policy.
