2022-01-26tools: mkimage: Show where signatures/keys are writtenSimon Glass
At present mkimage displays the node information but it is not clear what signing action was taken. Add a message that shows it. For now it only supports showing a single signing action, since that is the common case. Sample: Signature written to 'sha1-basic/test.fit', node '/configurations/conf-1/signature' Public key written to 'sha1-basic/sandbox-u-boot.dtb', node '/signature/key-dev' Signed-off-by: Simon Glass <sjg@chromium.org>
2022-01-26tools: Avoid leaving extra data at the end of copied filesSimon Glass
The copyfile() implementation has strange behaviour if the destination file already exists. Update it to ensure that any existing data in the destination file is dropped. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-01-26tools: Move copyfile() into a common fileSimon Glass
This function is useful in other places. Move it to a common file. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-01-24tools/fitimage: make sure dumpimage still works when "@" are detectedStefan Eichenberger
fit_verify_header fails if it detects unit addresses "@". However, this will break tools like dumpimage on fit images which worked with previous versions of the tool (e.g. 2020.04 vs 2021.07). As an example the output of: dumpimage -l <fit image> is: FIT description: U-Boot fitImage for Linux Distribution Created: Thu Jan 1 01:00:00 1970 Image 0 (kernel@1) Description: Linux kernel Created: Thu Jan 1 01:00:00 1970 Type: Kernel Image Compression: gzip compressed Data Size: 6442456 Bytes = 6291.46 KiB = 6.14 MiB Architecture: AArch64 OS: Linux Load Address: 0x80080000 Entry Point: 0x80080000 Hash algo: sha256 Hash value: ...

2021-02-15image: Adjust the workings of fit_check_format()Simon Glass
At present this function does not accept a size for the FIT. This means that it must be read from the FIT itself, introducing potential security risk. Update the function to include a size parameter, which can be invalid, in which case fit_check_format() calculates it. For now no callers pass the size, but this can be updated later. Also adjust the return value to an error code so that all the different types of problems can be distinguished by the user.

2019-05-18tools: use read-only mmap in fit_check_signLuca Boccassi
Add an option to open files in read-only mode in mmap_fdt so that fit_check_sign can be used to inspect files on read-only filesystems. For example, this is useful when a key is shipped in a read-only rootfs or squashfs. Signed-off-by: Luca Boccassi <luca.boccassi@microsoft.com>
2019-03-08fdt: Fix FIT header verification in mkimage and conduct same checks as bootmJordan Hand
FIT header verification in mkimage was treating a return code as a boolean, which meant that failures in validating the fit were seen as successes. Additionally, mkimage was checking all formats to find a header which passes validation, rather than using the image type specified to mkimage. checkpatch.pl checks for lines ending with '(' and alignment matching open parentheses are ignored to keep with existing coding style.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2014-06-11mkimage: Automatically make space in FDT when fullSimon Glass
When adding hashes or signatures, the target FDT may be full. Detect this and automatically try again after making 1KB of space. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-06-11Improve error handling in fit_commonSimon Glass
Make the error handling common, and make sure the file is always closed on error. Rename the parameter to be more description and add comments. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-03-21tools, fit: add fit_info host commandHeiko Schocher
add fit_info command to the host tools. This command prints the name, offset and the len from a property from a node in a fit file. This info can be used to extract a properties data with linux tools, for example "dd". Signed-off-by: Heiko Schocher <hs@denx.de> Acked-by: Simon Glass <sjg@chromium.org>
