2020-12-03	cbfs: Add verification for RO CBFS metadata hash	Julius Werner
	This patch adds the first stage of the new CONFIG_CBFS_VERIFICATION feature. It's not useful to end-users in this stage so it cannot be selected in menuconfig (and should not be used other than for development) yet. With this patch coreboot can verify the metadata hash of the RO CBFS when it starts booting, but it does not verify individual files yet. Likewise, verifying RW CBFSes with vboot is not yet supported. Verification is bootstrapped from a "metadata hash anchor" structure that is embedded in the bootblock code and marked by a unique magic number. This anchor contains both the CBFS metadata hash and a separate hash for the FMAP which is required to find the primary CBFS. Both are verified on first use in the bootblock (and halt the system on failure). The CONFIG_TOCTOU_SAFETY option is also added for illustrative purposes to show some paths that need to be different when full protection against TOCTOU (time-of-check vs. time-of-use) attacks is desired. For normal verification it is sufficient to check the FMAP and the CBFS metadata hash only once in the bootblock -- for TOCTOU verification we do the same, but we need to be extra careful that we do not re-read the FMAP or any CBFS metadata in later stages. This is mostly achieved by depending on the CBFS metadata cache and FMAP cache features, but we allow for one edge case in case the RW CBFS metadata cache overflows (which may happen during an RW update and could otherwise no longer be fixed because mcache size is defined by RO code). This code is added to demonstrate design intent but won't really matter until RW CBFS verification can be supported.

2020-12-03	cbfstool: Use cbfs_serialized.h and standard vboot helpers	Julius Werner
	This patch reduces some code duplication in cbfstool by switching it to use the CBFS data structure definitions in commonlib rather than its own private copy. In addition, replace a few custom helpers related to hash algorithms with the official vboot APIs of the same purpose.

2018-06-15	util/cbfstool: Support FIT payloads	Patrick Rudolph
	In order to support booting a GNU/Linux payload on non x86, the FIT format should be used, as it is the defacto standard on ARM. Due to greater complexity of FIT it is not converted to simple ELF format. Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'. The payload is included as is, with no special header. The code can determine the type at runtime using the CBFS_TYPE field. Support for parsing FIT payloads in coreboot is added in a follow on commit. Compression of FIT payloads is not supported, as the FIT sections might be compressed itself. Starting at this point a CBFS payload/ can be either of type FIT or SELF. Tested on Cavium SoC.

2016-08-27	cbfs: Add "struct" file type and associated helpers	Julius Werner
	This patch adds functionality to compile a C data structure into a raw binary file, add it to CBFS and allow coreboot to load it at runtime. This is useful in all cases where we need to be able to have several larger data sets available in an image, but will only require a small subset of them at boot (a classic example would be DRAM parameters) or only require it in certain boot modes. This allows us to load less data from flash and increase boot speed compared to solutions that compile all data sets into a stage. Each structure has to be defined in a separate .c file which contains no functions and only a single global variable. The data type must be serialization safe (composed of only fixed-width types, paying attention to padding). It must be added to CBFS in a Makefile with the 'struct' file processor.

2015-09-01	cbfstool: allow compression at file header level	Daisuke Nojiri
	Currently, compression is only allowed at subheader level (e.g. cbfs_stage, cbfs_payload_segment). This change adds compression field to each file's header so that any cbfs file can be compressed. With the necessary additions in coreboot and libpayload, the following sample code can load a compressed file: const char name = "foo.bmp"; struct cbfs_file file = cbfs_get_file(media, name); void *dst = malloc(ntohl(file->uncompressed_size)); dst = cbfs_get_file_content(media, name, type, file, dst); cbfs_stage and cbfs_payload_segment continue to support compression at subheader level because stages and payloads have to be decompressed to the load address, which is stored in the subheader. For these, file level compression should be turned off.

2015-05-13	cbfstool: New image format w/ required FMAP and w/o CBFS master header	Sol Boucher
	These new-style firmware images use the FMAP of the root of knowledge about their layout, which allows them to have sections containing raw data whose offset and size can easily be determined at runtime or when modifying or flashing the image. Furthermore, they can even have multiple CBFSes, each of which occupies a different FMAP region. It is assumed that the first entry of each CBFS, including the primary one, will be located right at the start of its region. This means that the bootblock needs to be moved into its own FMAP region, but makes the CBFS master header obsolete because, with the exception of the version and alignment, all its fields are redundant once its CBFS has an entry in the FMAP. The version code will be addressed in a future commit before the new format comes into use, while the alignment will just be defined to 64 bytes in both cbfstool and coreboot itself, since there's almost no reason to ever change it in practice. The version code field and all necessary coreboot changes will come separately.

	This completes the improvements to the ELF file parsing code. We can now parse section headers too, across all 4 combinations of word size and endianness. I had hoped to completely remove the use of htonl until I found it in cbfs_image.c. That's a battle for another day. There's now a handy macro to create magic numbers in host byte order. I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe we can use it for the others too, but this is sensitive code and I'd rather change one thing at a time. To maximize the ease of use for users, elf parsing is accomplished with just one function: int elf_headers(const struct buffer pinput, Elf64_Ehdr ehdr, Elf64_Phdr pphdr, Elf64_Shdr pshdr) which requires the ehdr and pphdr pointers to be non-NULL, but allows the pshdr to be NULL. If pshdr is NULL, the code will not try to read in section headers. To satisfy our powerful scripts, I had to remove the ^M from an unrelated microcode file.

Hence we also increase the version number in the master header.

2012-11-12	cbfstool: Rework to use getopt style parameters	Stefan Reinauer
	- Adding more and more optional and non-optional parameters bloated cbfstool and made the code hard to read with a lot of parsing in the actual cbfs handling functions. This change switches over to use getopt style options for everything but command and cbfs file name. - This allows us to simplify the coreboot Makefiles a bit - Also, add guards to include files - Fix some 80+ character lines - Add more detailed error reporting - Free memory we're allocating Signed-off-by: Stefan Reinauer <reinauer@google.com> Change-Id: Ia9137942deb8d26bbb30068e6de72466afe9b0a7 Reviewed-on: http://review.coreboot.org/1800 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2011-01-14	Allow coreboot to initialize CMOS if checksum is invalid.	Patrick Georgi
	If a file "cmos.default", type "cmos default"(0xaa) is in CBFS, a wrong checksum leads to coreboot rewriting the first 128 bytes (except for clock data) with the data in cmos.default, then reboots the system so every component of coreboot works with the same set of values.

2009-05-08	I have made a very simple mod to cbfstool that is compatible with the	Ronald G. Minnich
	src/lib/ code in coreboot. I.e. the tool changes but the coreboot code does not. Currently, as cbfstool manages the ROM, there are files and empty space. To allocate files, the code does, first, a walk of the headers and, if that fails, does a brute-force search of the rest of the space. We all agree that the brute-force search has lots of problems from a performance and correctness standpoint. I've made a slight change. Instead of an "empty space" area with no valid headers, I've made a header for the empty space. So cbfs creation looks like this: - set up the boot block - create a file, of type CBFS_COMPONENT_NULL, that contains the empty space. CBFS_COMPONENT_NULL was already defined in cbfs.h Here's an example: [rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs create 1048576 2048 (cbfstool) E: Unable to open (null): Bad address [rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs print testcbfs: 1024 kB, bootblocksize 2048, romsize 1048576, offset 0x0 Alignment: 16 bytes Name Offset Type Size 0x0 0xffffffff 1046456 So how do we create a new file? It's easy: walk the files and find a file of type CBFS_COMPONENT_NULL, which is as large or larger than the file you are trying to create. Then you use that file. - if the file is the same size as the NULL file, then it's easy: take it - if the file is smaller than the NULL file, you split the NULL file into two parts. note that this works in the base case: the base case is that the whole storage is CBFS_COMPONENT_NULL. Here's an example of adding a file. [rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs add-stage testfixed t [rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs print testcbfs: 1024 kB, bootblocksize 2048, romsize 1048576, offset 0x0 Alignment: 16 bytes Name Offset Type Size t 0x0 stage 23176 0x5ab0 0xffffffff 1023240 Note that the NULL split and got smaller. But the entire ROM is still contained by the two files. To walk this entire rom will require two FLASH accesses. Add another file: [rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs add-stage testfixed tt [rminnich@xcpu2 cbfstool]$ ./cbfstool testcbfs print testcbfs: 1024 kB, bootblocksize 2048, romsize 1048576, offset 0x0 Alignment: 16 bytes Name Offset Type Size t 0x0 stage 23176 tt 0x5ab0 stage 23176 0xb560 0xffffffff 1000024 [rminnich@xcpu2 cbfstool]$ So, taking current ROMs as an example, I can reduce FLASH accesses for cbfs from (potentially) thousands to (typically) less than 10. Index: fs.c Changes for readability and cleanliness. Move common blobs of code to functions. New function: rom_alloc,which allocates files by finding NULL files and using/splitting. Other changes as needed to support this usage. Index: util.c Creating a cbfs archive now requires creation of a NULL file covering the file system space. Index: cbfs.h Add a DELETED file type with value 0. Any file can be marked deleted by zero its type; this is a FLASH-friendly definition for all known FLASH types. Signed-off-by: Ronald G. Minnich <rminnich@gmail.com> I think it is a step in the right direction. Could you add the function prototype to cbfstool.h?
