*-flash.init: Use busybox ash Busybox no longer has CONFIG_BASH since we are deploying bash on most boards. We also should clearly indicate which scripts cannot use bashisms. Change shebang in x230-flash.init, t430-flash.init, flash.sh to /bin/ash. Execute /bin/sh for interactive shells. Move key functions needed by those scripts to initrd/etc/ash_functions. Source ash_functions instead of functions in those scripts, so any bashisms in other functions won't break parsing of the script in ash. Signed-off-by: Jonathon Hall <jonathon.hall@puri.sm>

Use global /tmp/config that combines multiple config files As part of the config gui we want to be able to have the system define new config options without them being lost if the user makes their own changes in CBFS. To allow that this change creates a function initiated in init that combines all /etc/config* files into /tmp/config. All existing scripts have been changed to source /tmp/config instead of /etc/config. The config-gui.sh script now uses /etc/config.user to hold user configuration options but the combine_configs function will allow that to expand as others want to split configuration out further. As it stands here are the current config files: /etc/config -- Compiled-in configuration options /etc/config.user -- User preferences that override /etc/config /tmp/config -- Running config referenced by the BIOS, combination of existing configs

Add TRACE function tracing function to output on console when enabled - Add TRACE function tracing output under etc/functions, depending on CONFIG_ENABLE_FUNCTION_TRACING_OUTPUT enabled in board configs - Replace current DEBUG to TRACE calls in code, reserving DEBUG calls for more verbose debugging later on (output of variables etc) - add 'export CONFIG_ENABLE_FUNCTION_TRACING_OUTPUT=y' in qemu-coreboot(fb)whiptail-tpm1(-hotp) boards to see it in action

Addition of qemu-(fb)whiptail-tpm2(-hotp) boards -coreboot support of TPM v2.0 (shared config for TPM2 support across all 4 previous variations) -swtpm set to be launched under TPM v2.0 mode under board config -Documentation file under each board.md softlinks to qemu-coreboot-fbwhiptail-tpm1.md (which has been generalized) This is skeleton for TPM v2 integration under Heads ------------- WiP TODO: - libcurl cannot be built as a tpm2-tools dependency as of now not sure why. curl currently needs to be added in board config to be built - Note: tpm-reset (master and here) needs some review, no handle of no tpm use case. Caller is responsible to not call it otherwise does nothing - init tries to bind fd and fails currently - Note: Check if whiptail is different of fbwhiptail in clearing screen. As of now every clear seems to be removed, still whiptail clears previous console output - When no OS' /boot can be mounted, do not try to TPM reset (will fail) - seal-hotpkey is not working properly - setting disk unlock key asks for TPM ownership passphrase (sealing in NV requires ownership, but text is misleading user as if reowning TPM) - We should cache input, feed tpm behind the scene and wipe passphrase and state clearly that this is TPM disk unlock kye passphrase. - primary key from TPM2 is invalid most of the time from kexec-select-boot and verifying global hashes but is setuped correctly at disk unlock key setup - would be nice to take advantage of bash function tracing to understand where we are for debugging purposes, code takes ash in consideration only - tpmr says it implements nv calls but actually doesn't. Removing those falsely wrapped functions would help. - Implementing them would be better - REVIEW TODOS IN CODE - READD CIRCLECI CONFIG Current state: - TPM unseal works without disk unlock key and generates TOTP properly (was missing die condition at unseal to not produce always good TOTP even if invalid) - TPM disk encryption key fails. Hypothesis is that sealing with USB drivers loaded and measures in inconsistent with sealed with/without. - TPM disk unsealing happens without USB modules being loaded in non-HOTP setup. This fails. - Current tests are with fbwhiptail (no clear called so having traces on command line of what happens) - Testing with HOTP implementation for sealing/unsealing since that forces USB module loads on each boot to remove this from failing possibilities
