In CB:41119, I sort of made up a mechanism on the fly for how to make the machine-parseable cbfstool print output extensible without breaking backwards compatibility for older scripts. But I only explained it in the commit message which is not very visible. This patch adds a comment to the function that generates that output so that people who want to change it can understand the intent.

2022-09-02cbfs/vboot: Adapt to new vb2_digest APIJulius Werner
CL:3825558 changes all vb2_digest and vb2_hash functions to take a new hwcrypto_allowed argument, to potentially let them try to call the vb2ex_hwcrypto API for hash calculation. This change will open hardware crypto acceleration up to all hash calculations in coreboot (most notably CBFS verification). As part of this change, the vb2_digest_buffer() function has been removed, so replace existing instances in coreboot with the newer vb2_hash_calculate() API. Due to the circular dependency of these changes with vboot, this patch also needs to update the vboot submodule: Updating from commit id 18cb85b5: 2load_kernel.c: Expose load kernel as vb2_api to commit id b827ddb9: tests: Ensure auxfw sync runs after EC sync This brings in 15 new commits.

2021-03-17cbfs: Move stage header into a CBFS attributeJulius Werner
The CBFS stage header is part of the file data (not the header) from CBFS's point of view, which is problematic for verification: in pre-RAM environments, there's usually not enough scratch space in CBFS_CACHE to load the full stage into memory, so it must be directly loaded into its final destination. However, that destination is decided from reading the stage header. There's no way we can verify the stage header without loading the whole file and we can't load the file without trusting the information in the stage header. To solve this problem, this patch changes the CBFS stage format to move the stage header out of the file contents and into a separate CBFS attribute. Attributes are part of the metadata, so they have already been verified before the file is loaded. Since CBFS stages are generally only meant to be used by coreboot itself and the coreboot build system builds cbfstool and all stages together in one go, maintaining backwards-compatibility should not be necessary. An older version of coreboot will build the old version of cbfstool and a newer version of coreboot will build the new version of cbfstool before using it to add stages to the final image, thus cbfstool and coreboot's stage loader should stay in sync. This only causes problems when someone stashes away a copy of cbfstool somewhere and later uses it to try to extract stages from a coreboot image built from a different revision... a debugging use-case that is hopefully rare enough that affected users can manually deal with finding a matching version of cbfstool. The SELF (payload) format, on the other hand, is designed to be used for binaries outside of coreboot that may use independent build systems and are more likely to be added with a potentially stale copy of cbfstool, so it would be more problematic to make a similar change for SELFs. It is not necessary for verification either, since they're usually only used in post-RAM environments and selfload() already maps SELFs to CBFS_CACHE before loading them to their final destination anyway (so they can be hashed at that time).

2021-02-18cbfstool: Replace FILENAME_ALIGN 16 with ATTRIBUTE_ALIGN 4Julius Werner
cbfstool has always had a CBFS_FILENAME_ALIGN that forces the filename field to be aligned upwards to the next 16-byte boundary. This was presumably done to align the file contents (which used to come immediately after the filename field). However, this hasn't really worked right ever since we introduced CBFS attributes. Attributes come between the filename and the contents, so what this code currently does is fill up the filename field with extra NUL-bytes to the boundary, and then just put the attributes behind it with whatever size they may be. The file contents don't end up with any alignment guarantee and the filename field is just wasting space. This patch removes the old FILENAME_ALIGN, and instead adds a new alignment of 4 for the attributes. 4 seems like a reasonable alignment to enforce since all existing attributes (with the exception of weird edge cases with the padding attribute) already use sizes divisible by 4 anyway, and the common attribute header fields have a natural alignment of 4. This means file contents will also have a minimum alignment guarantee of 4 -- files requiring a larger guarantee can still be added with the --alignment flag as usual.

2021-02-18cbfstool: Ensure attributes always come last in the metadataJulius Werner
In a rare placement edge case when adding a file with alignment requirements, cbfstool may need to generate a CBFS header that's slightly larger than it needs to be. The way we do this is by just increasing the data offset field in the CBFS header until the data falls to the desired value. This approach works but it may confuse parsing code in the presence of CBFS attributes. Normally, the whole area between the attribute offset and the data offset is filled with valid attributes written back to back, but when this header expansion occurs the attributes are followed by some garbage data (usually 0xff). Parsers are resilient against this but may show unexpected error messages. This patch solves the problem by moving the attribute offset forwards together with the data offset, so that the total area used for attributes doesn't change. Instead, the filename field becomes the expanded area, which is a closer match to how this worked when it was originally implemented (before attributes existed) and is less confusing for parsers since filenames are zero-terminated anyway.

2020-12-08util/cbfstool: Treat region offsets differently than absolute addressesFurquan Shaikh
cbfstool overloads baseaddress to represent multiple things: 1. Address in SPI flash space 2. Address in host space (for x86 platforms) 3. Offset from end of region (accepted as negative number) This was done so that the different functions that use these addresses/offsets don't need to be aware of what the value represents and can use the helper functions convert_to_from* to get the required values. Thus, even if the user provides a negative value to represent offset from end of region, it was stored as an unsigned integer. There are special checks in convert_to_from_top_aligned which guesses if the value provided is really an offset from the end of region and converts it to an offset from start of region. This has worked okay until now for x86 platforms because there is a single fixed decode window mapping the SPI flash to host address space. However, going forward new platforms might need to support more decode windows that are not contiguous in the host space. Thus, it is important to distinguish between offsets from end of region and addresses in host/SPI flash space and treat them separately. As a first step towards supporting this requirement for multiple decode windows on new platforms, this change handles the negative offset provided as input in dispatch_command before the requested cbfs operation is performed. This change adds baseaddress_input, headeroffset_input and cbfsoffset_input to struct param and converts them to offsets from start of region before storing into baseaddress, headeroffset and cbfsoffset if the inputs are negative. In follow up changes, cbfstool will be extended to add support for multiple decode windows. BUG=b:171534504 TEST=Verified using abuild with timeless option for all coreboot boards that there is no change in the resultant coreboot.rom file.

2020-12-03cbfstool: Hide hash printing behind -v and add to parseable outputJulius Werner
With the upcoming introduction of CBFS verification, a lot more CBFS files will have hashes. The current cbfstool default of always printing hash attributes when they exist will make cbfstool print very messy. Therefore, hide hash attribute output unless the user passed -v. It would also be useful to be able to get file attributes like hashes in machine parseable output. Unfortunately, our machine parseable format (-k) doesn't really seem designed to be extensible. To avoid breaking older parsers, this patch adds new attribute output behind -v (which hopefully no current users pass since it doesn't change anything for -k at the moment). With this patch cbfstool print -k -v may print an arbitrary amount of extra tokens behind the predefined ones on a file line. Tokens always begin with an identifying string (e.g. 'hash'), followed by extra fields that should be separated by colons. Multiple tokens are separated by the normal separator character (tab). cbfstool print -k -v may also print additional information that applies to the whole CBFS on separate lines. These lines will always begin with a '[' (which hopefully nobody would use as a CBFS filename character although we technically have no restrictions at the moment).

This function name clashes with cbfs_walk() in the new commonlib CBFS stack, so rename it to cbfs_legacy_walk(). While we could replace it with the new commonlib implementation, it still has support for certain features in the deprecated pre-FMAP CBFSes (such as non-standard header alignment), which are needed to handle old files but probably not something we'd want to burden the commonlib implementation with. So until we decide to deprecate support for those files from cbfstool as well, it seems easier to just keep the existing implementation here.

2016-02-22cbfs: Add LZ4 in-place decompression support for pre-RAM stagesJulius Werner
This patch ports the LZ4 decompression code that debuted in libpayload last year to coreboot for use in CBFS stages (upgrading the base algorithm to LZ4's dev branch to access the new in-place decompression checks). This is especially useful for pre-RAM stages in constrained SRAM-based systems, which previously could not be compressed due to the size requirements of the LZMA scratchpad and bounce buffer. The LZ4 algorithm offers a very lean decompressor function and in-place decompression support to achieve roughly the same boot speed gains (trading compression ratio for decompression time) with nearly no memory overhead. For now we only activate it for the stages that had previously not been compressed at all on non-XIP (read: non-x86) boards. In the future we may also consider replacing LZMA completely for certain boards, since which algorithm wins out on boot speed depends on board-specific parameters (architecture, processor speed, SPI transfer rate, etc.). BRANCH=None BUG=None TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on Oak to be about ~20ms faster (cutting load times for affected stages almost in half).

While assembling CBFS images within the RW slots on Chrome OS machines the current approach is to 'cbfstool copy' from the RO CBFS to each RW CBFS. Additional fixups are required such as removing unneeded files from the RW CBFS (e.g. verstage) as well as removing and adding back files with the proper arguments (FSP relocation as well as romstage XIP relocation). This ends up leaving holes in the RW CBFS. To speed up RW CBFS slot hashing it's beneficial to pack all non-empty files together at the beginning of the CBFS. Therefore, provide the 'compact' command which bubbles all the empty entries to the end of the CBFS.

2015-07-18cbfstool: rename checksum to attributes_offsetPatrick Georgi
So far it's still unused, but its purpose will change: It will become an offset to another structure that contains additional file attributes. This change is compatible because the binary format doesn't change and so far the field was always set to 0, which can serve nicely as 'unused' field.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>
2015-05-13cbfstool: Support top-aligned addresses for new-format imagesSol Boucher
The cbfstool handling of new-style FMAP-driven "partitioned" images originally disallowed the use of x86-style top-aligned addresses with the add.* and layout actions because it wasn't obvious how they should work, especially since the normal addressing is done relative to each individual region for these types of images. Not surprisingly, however, the x86 portions of the build system make copious use of top-aligned addresses, so this allows their use with new images and specifies their behavior as being relative to the *image* end---not the region end---just as it is for legacy images.

2015-05-13cbfstool: New image format w/ required FMAP and w/o CBFS master headerSol 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. BUG=chromium:470407 TEST=Build panther and nyan_big coreboot.rom and image.bin images with and without this patch, diff their hexdumps, and note that no locations differ except for those that do between subsequent builds of the same codebase. Try working with new-style images: use fmaptool to produce an FMAP section from an fmd file having raw sections and multiple CBFSes, pass the resulting file to cbfstool create -M -F, then try printing its layout and CBFSes' contents, add and remove CBFS files, and read and write raw sections.
