# TPM2 tools program
modules-$(CONFIG_TPM2_TOOLS) += tpm2-tools
tpm2-tools: Change sense of CONFIG_TPM to mean any TPM, not just TPM1. Most logic throughout Heads doesn't need to know TPM1 versus TPM2 (and shouldn't, the differences should be localized). Some checks were incorrect and are fixed by this change. Most checks are now unchanged relative to master. There are not that many places outside of tpmr that need to differentiate TPM1 and TPM2. Some of those are duplicate code that should be consolidated (seal-hotpkey, unseal-totp, unseal-hotp), and some more are probably good candidates for abstracting in tpmr so the business logic doesn't have to know TPM1 vs. TPM2. Previously, CONFIG_TPM could be variously 'y', 'n', or empty. Now it is always 'y' or 'n', and 'y' means "any TPM". Board configs are unchanged, setting CONFIG_TPM2_TOOLS=y implies CONFIG_TPM=y so this doesn't have to be duplicated and can't be mistakenly mismatched. There were a few checks for CONFIG_TPM = n that only coincidentally worked for TPM2 because CONFIG_TPM was empty (not 'n'). This test is now OK, but the checks were also cleaned up to '!= "y"' for robustness. Signed-off-by: Jonathon Hall <jonathon.hall@puri.sm>

OpenSSL (libcrypto): patch so that crypto/buildinfo.h generated by perl script contains reproducible date and fake compiler_flags hardcode VERSION='reproducible_build' into generated configure script to get rid of generate random git abbrev 8/12 chars (could not find source) patches/openssl-3.0.8.patch: clean up tpm2-tools/tpm2-tss: hack configure scripts to not contain hardcoded libs and other rpath related strings, using sed instead of patching configure script like cryptsetup2 patch Will be clened up in other commits. Leaving here as trace for autotools sed patching for reproducible builds. CircleCI: change working dir from project->heads so that CircleCI and local builds are from heads directory, helping reproducible builds TODO: change other patches a well and generalize to gpg toolstack, removing patches that are a maintainership burden.
