2021-12-26tools: avoid OpenSSL deprecation warningsHeinrich Schuchardt3-0/+7
Our Gitlab CI buildsystem is set up to treat warnings as errors. With OpenSSL 3.0 a lot of deprecation warnings occur. With the patch compatibility with OpenSSL 1.1.1 is declared. In the long run we should upgrade our code to use the current API. A -Wdiscarded-qualifiers warning is muted by casting. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>
2021-12-26efi_loader: Don't limit the StMM buffer size explicitlyIlias Apalodimas1-11/+5
Currently we allow and explicitly check a single shared page with StandAloneMM. This is dictated by OP-TEE which runs the application. However there's no way for us dynamically discover the number of pages we are allowed to use. Since writing big EFI signature list variable requires more than a page, OP-TEE has bumped the number of shared pages to four. Let's remove our explicit check and allow the request to reach OP-TEE even if it's bigger than what it supports. There's no need to sanitize the number of pages internally. OP-TEE will fail if we try to write more than it's allowed. The error will just trigger later on, during the StMM access. While at it add an error message to help users figure out what failed.

2021-12-09efi_loader: correctly handle no tpm device errorMasahisa Kojima3-8/+18
When the TCG2 protocol is installed in efi_tcg2_register(), TPM2 device must be present. tcg2_measure_pe_image() expects that TCP2 protocol is installed and TPM device is available. If TCG2 Protocol is installed but TPM device is not found, tcg2_measure_pe_image() returns EFI_SECURITY_VIOLATION and efi_load_image() ends with failure. The same error handling is applied to efi_tcg2_measure_efi_app_invocation(). Signed-off-by: Masahisa Kojima <masahisa.kojima@linaro.org> Reviewed-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>

2021-11-30efi_loader: Extend PCR's for firmware measurementsRuchika Gupta1-0/+76
Firmwares before U-Boot may be capable of doing tpm measurements and passing them to U-Boot in the form of eventlog. However there may be scenarios where the firmwares don't have TPM driver and are not capable of extending the measurements in the PCRs. Based on TCG spec, if previous firnware has extended PCR's, PCR0 would not be 0. So, read the PCR0 to determine if the PCR's need to be extended as eventlog is parsed or not.

Platforms may have support to measure their initial firmware components and pass the event log to u-boot. The event log address can be passed in property tpm_event_log_addr and tpm_event_log_size of the tpm node. Platforms may choose their own specific mechanism to do so. A weak function is added to check if even log has been passed to u-boot from earlier firmware components.

2021-11-26efi: Call bootm_disable_interrupts earlier in efi_exit_boot_servicesTom Rini1-3/+1
If we look at the path that bootm/booti take when preparing to boot the OS, we see that as part of (or prior to calling do_bootm_states, explicitly) the process, bootm_disable_interrupts() is called prior to announce_and_cleanup() which is where udc_disconnect() / board_quiesce_devices() / dm_remove_devices_flags() are called from. In the EFI path, these are called afterwards. In efi_exit_boot_services() however we have been calling bootm_disable_interrupts() after the above functions, as part of ensuring that we disable interrupts as required by the spec. However, bootm_disable_interrupts() is also where we go and call usb_stop(). While this has been fine before, on the TI J721E platform this leads us to an exception. This exception seems likely to be the case that we're trying to stop devices that we have already disabled clocks for. The most direct way to handle this particular problem is to make EFI behave like the do_bootm_states() process and ensure we call bootm_disable_interrupts() prior to ending up in usb_stop().

As described in the TCG spec [1] in sections 7.1.1 and 7.1.2 the FinalEvent table should include events after GetEventLog has been called. This currently works for us as long as the kernel is the only EFI application calling that. Specifically we only implement what's described in 7.1.1. So refactor the code a bit and support EFI application(s) calling GetEventLog. Events will now be logged in both the EventLog and FinalEvent table as long as ExitBootServices haven't been invoked.

Most EFI implementations use 64-bit but U-Boot only supports running as a 32-bit app at present. While efi-x86_payload64 does boot from 64-bit UEFI it immediately changes back to 32-bit before starting U-Boot. In order to support a 64-bit U-Boot app, update the Kconfig to add an option for 32/64 bit. Update the prompt for the existing option so it is clear it relates to the stub. Move both up to just under the choice that controls them, since this looks better and the menu. Use CONFIG_EFI_APP in the Makefile instead of CONFIG_TARGET_EFI_APP, since the latter is specific to a single target and we will have two.
