lib/digsig: Use SHA-1 library instead of crypto_shash

2025-10-03T11:50:56+00:00

Now that a SHA-1 library API is available, use it instead of crypto_shash. This is simpler and faster. Signed-off-by: Eric Biggers Reviewed-by: Paul Menzel Signed-off-by: Mimi Zohar

2025-06-30T16:31:57+00:00

Move all CRC files in lib/ into a subdirectory lib/crc/ to keep them from cluttering up the main lib/ directory. Reviewed-by: "Martin K. Petersen" Acked-by: Ingo Molnar Acked-by: "Jason A.

pldmfw: Select CRC32 when PLDMFW is selected

2025-06-16T21:12:08+00:00

pldmfw calls crc32 code and depends on it being enabled, else there is a link error as follows. So PLDMFW should select CRC32. lib/pldmfw/pldmfw.o: In function `pldmfw_flash_image': pldmfw.c:(.text+0x70f): undefined reference to `crc32_le_base' This problem was introduced by commit b8265621f488 ("Add pldmfw library for PLDM firmware update"). It manifests as of commit d69ea414c9b4 ("ice: implement device flash update via devlink"). And is more likely to occur as of commit 9ad19171b6d6 ("lib/crc: remove unnecessary prompt for CONFIG_CRC32 and drop 'default y'"). Found by chance while exercising builds based on tinyconfig.

lib/crc: remove CONFIG_LIBCRC32C

2025-04-04T18:31:42+00:00

Now that LIBCRC32C does nothing besides select CRC32, make every option that selects LIBCRC32C instead select CRC32 directly. Then remove LIBCRC32C.

lib/crc: document all the CRC library kconfig options

2025-04-04T18:31:42+00:00

Previous commits removed all the original CRC kconfig help text, since it was oriented towards people configuring the kernel, and the options are no longer user-selectable. However, it's still useful for there to be help text for kernel developers. Add this. Reviewed-by: Christoph Hellwig Reviewed-by: "Martin K.
