* fmap: ignore areas with zero sizePeter Marheine2023-03-141-0/+10
| | | | | | | | | | | | | | | | | | | | | | | It's impossible for flashrom_layout to represent zero-sized flash regions but it is possible for a fmap to contain a zero-sized region which causes the resulting layout to fail layout_sanity_checks(), preventing use of that fmap. Because it would very rarely make sense to be able to operate on zero-sized regions anyway and changing layouts to be able to support zero-size regions would entail large changes, instead ignore zero-size regions when present in fmap. TEST=Warning is now printed when using fmap that contains a zero-sized area, and operations on other regions are allowed to proceed.

* libflashrom: Add flags to skip unreadable and unwritable regionsNikolai Artemiev2022-12-181-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | Add flags to allow libflashrom users to configure how operations that include unreadable or unwritable regions should be behave. If the flags are set to true, a read/write operation will just skip the inaccessible region and will still be executed in other regions. If the flags are set to false, the inaccessible region will cause the entire operation to fail.

| | | | | | | | | | | | | | | | | | | | | The doxygen documentation was in the libflashrom.c file. Move the documentation to the libflashrom.h file. This allows foreign function interface binding generators (eg rust bindgen) that operate on the .h file to generate documentation for the target language. Some doxygen errors were also corrected, mostly undocumented or wrongly labeled parameters. To test, I have diffed and inspected the doxygen documentation before and after the change. All functions are documented the same, and the structs and enums are now also included in the docs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a generic framework to allow opaque programmers to implement writeprotect operations and uses the framework to support writeprotect operations on linux MTD device files. The generic framework comprises three new functions in `struct opaque_master` that are called from libflashrom: - wp_write_cfg() - wp_read_cfg() - wp_get_ranges() For linux_mtd, only the read/write functions are implemented. Linux's MTD interface doesn't provide a way to get available ranges, so calling get_wp_ranges() on the linux_mtd master will return FLASHROM_WP_ERR_RANGE_LIST_UNAVAILABLE.

* libflashrom/fmap: Don't use off_t for flash offsetsJulius Werner2022-02-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | off_t is a special POSIX type that is used to represent file offsets in certain APIs (e.g. lseek(), mmap()), and should not be reused to represent anything else (such as flash offsets). In particular, the width of the type may change based on the definition of the _FILE_OFFSET_BITS macro. Using such a type at the libflashrom interface is particularly dangerous, because if a program is built with a different _FILE_OFFSET_BITS value than libflashrom, the resulting ABI corruption will cause very very nasty and confusing bugs. This patch replaces all instances of off_t that are not related to file offsets with (s)size_t. BUG=b:219811851 TEST=`elogtool list` on cherry.

* libflashrom.c: Use correct type for sizeofAngel Pons2020-05-031-1/+1
| | | | | | | | | | | | | | | As we want to allocate an array of `flashrom_board_info` structs, use that type in sizeof. This did not cause problems as `board_info` was at least as big as `flashrom_board_info`, but nothing guarantees it.

* Add support to get layout from fmap (e.g. coreboot rom)Arthur Heymans2018-10-231-0/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Flashmap, or simply fmap, is a binary data format for describing region offsets, sizes, and certain attributes and is widely used by coreboot. This patch adds support for the fmap data format version 1.1 and adds --fmap and --fmap-file arguments. Using --fmap will make flashrom to search the ROM content for fmap data. Using --fmap-file will make flashrom search a supplied file for fmap data. An example of how to update the COREBOOT region of a ROM: flashrom -p programmer --fmap -w coreboot.rom -i COREBOOT flashrom -p programmer --fmap-file coreboot.rom -w coreboot.rom -i COREBOOT The fmap functions are mostly copied from cbfstool. Currently it is made mutually exclusive with other layout options until we are more clever about this input.

* Add a convenient libflashrom interfaceNico Huber2017-06-031-0/+334
This adds a minimal libflashrom interface based on the draft in the wiki. While the glue code in libflashrom.c is build on top of the existing code instead on overhauling it, the interface in libflashrom.h is supposed to be stable. So we can keep the interface and adapt internals later if favoured, without breaking clients. A new make target, libinstall, is also added. It installs libflashrom.a and libflashrom.h in lib/ and include/ dirs respectively. Hooking this into the build would break linking of the CLI and is post- poned until that got fixed. v2: Rebase and fixes by Anton Kochkov. v3: o fl_image_*() rewritten with layout support (touch only included regions). o Moved read/erase/write/verify operations to flashrom.c. o Added layout pointer and flags to the flash context. v4: Removed libflashrom.o from LIB_OBJS until CLI is adapted. v5: o Incorporated David's comments. o Added `fl_flashprog_t` as dummy parameter to hide the fact that we have global state all around, and for future-proofness ofc. v6: o Change namespace prefix to flashrom_. o Remove typedefs.
