2022-02-05efi_loader: use %zu not %zd to print efi_uintn_tHeinrich Schuchardt
efi_uintnt_t is an unsigned type. We should avoid showing negative numbers. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>
2022-02-05efi_loader: fix device path to text protocolHeinrich Schuchardt
The printing of a file path node must properly handle: * odd length of the device path node * UTF-16 character only partially contained in device path node * buffer overflow due to very long file path Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>

2022-02-05efi_selftest: merge FDT and RISC-V testsHeinrich Schuchardt
The test for the RISCV_EFI_BOOT_PROTOCOL retrieves the boot hart id via the protocol and compares it to the value of the boot hart id in the device tree. The boot hart id is already retrieved from the device tree in the FDT test. Merge the two tests to avoid code duplication. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>

2022-01-29efi_loader: hash the image once before checking against db/dbxIlias Apalodimas
We don't have to recalculate the image hash every time we check against a new db/dbx entry. So let's add a flag forcing it to run once since we only support sha256 hashes Suggested-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com> Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Reviewed-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com>
2022-01-29efi_loader: correctly handle mixed hashes and signatures in dbIlias Apalodimas
A mix of signatures and hashes in db doesn't always work as intended. Currently if the digest algorithm is not explicitly set to sha256 we stop walking the security database and reject the image. That's problematic in case we find and try to check a signature before inspecting the sha256 hash. If the image is unsigned we will reject it even if the digest matches. Since we no longer reject the image on unknown algorithms add an explicit check and reject the image if any other hash algorithm apart from sha256 is detected on dbx.

2022-01-25acpi: Collect tables in the acpi_item listSimon Glass
At present this list is used to collect items within the DSDT and SSDT tables. It is useful for it to collect the whole tables as well, so there is a list of what was created and which write created each one. Refactor the code accordingly. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-01-25x86: Move acpi_get_rsdp_addr() ACPI tables to the writerSimon Glass
Move this over to use a writer file, moving the code from the x86 implementation. There is no need to store a separate variable since we can simply access the ACPI context. With this, the original monolithic x86 function for writing ACPI tables is gone. Note that QEMU has its own implementation. Signed-off-by: Simon Glass <sjg@chromium.org>

2022-01-25x86: Use the ACPI table writerSimon Glass
Use the new ACPI writer to write the ACPI tables. At present this is all done in one monolithic function. Future work will split this out. Unfortunately the QFW write_acpi_tables() function conflicts with the 'writer' version, so disable that for sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-01-25x86: acpi: Split out context creation from base tablesSimon Glass
At present acpi_setup_base_tables() both sets up the ACPI context and writes out the base tables. We want to use an ACPI writer to write the base tables, so split this function into two, with acpi_setup_ctx() doing the context set, and acpi_setup_base_tables() just doing the base tables. Disable the writer's write_acpi_tables() function for now, to avoid build errors. It is enabled in a following patch. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-01-25acpi: Add a linker list for ACPI tablesSimon Glass
At present we call lots of functions to generate the required ACPI tables. It would be better to standardise these functions and allow them to be automatically collected and used when needed. Add a linker list to handle this. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-01-25acpi: Use finer-grained control of ACPI-table generationSimon Glass
Rather than keying everything off ACPIGEN, use the main GENERATE_ACPI_TABLE option to determine whether the core ACPI code is included. Make sure these option are not enabled in SPL/TPL since we never generate tables there. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-01-25efi: Correct address handling with ACPI tablesSimon Glass
The current EFI implementation confuses pointers and addresses. Normally we can get away with this but in the case of sandbox it causes failures. Despite the fact that efi_allocate_pages() returns a u64, it is actually a pointer, not an address. Add special handling to avoid a crash when running 'bootefi hello'.

2022-01-19lib/crypto: Enable more algorithms in cert verificationIlias Apalodimas
Right now the code explicitly limits us to sha1,256 hashes with RSA2048 encryption. But the limitation is artificial since U-Boot supports a wider range of algorithms. The internal image_get_[checksum|crypto]_algo() functions expect an argument in the format of <checksum>,<crypto>. So let's remove the size checking and create the needed string on the fly in order to support more hash/signing combinations. Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>
