lib: ecdsa: Implement UCLASS_ECDSA verification on target

2021-08-16T08:49:35Z

Implement the crypto_algo .verify() function for ecdsa256. Because it backends on UCLASS_ECDSA, this change is focused on parsing the keys from devicetree and passing this information to the specific UCLASS driver.

lib: Create a new Kconfig option for charset conversion

2021-07-28T18:27:54Z

Rather than looking at two KConfig options in the Makefile, create a new Kconfig option for compiling lib/charset.c Enable it for UFS also, which needs this support. Signed-off-by: Simon Glass Reviewed-by: Heinrich Schuchardt

lib: add crypt subsystem

2021-07-23T17:36:14Z

Add the basic functionality required to support the standard crypt format. The files crypt-sha256.c and crypt-sha512.c originate from libxcrypt and their formatting is therefor retained. The integration is done via a crypt_compare() function in crypt.c. ``` libxcrypt $ git describe --long --always --all tags/v4.4.17-0-g6b110bc ``` Signed-off-by: Steffen Jaeckel Reviewed-by: Simon Glass Reviewed-by: Heiko Schocher

lib: move rtc-lib.c to lib

2021-07-14T20:57:35Z

Function rtc_to_tm() is needed for FAT file system support even if we don't have a real time clock. So move it from drivers/ to lib/. Signed-off-by: Heinrich Schuchardt Reviewed-by: Bin Meng

lib: rational: copy the rational fraction lib routines from Linux

2021-06-11T11:04:52Z

Copy the best rational approximation calculation routines from Linux. Typical usecase for these routines is to calculate the M/N divider values for PLLs to reach a specific clock rate. This is based on linux kernel commit: "lib/math/rational.c: fix possible incorrect result from rational fractions helper" (sha1: 323dd2c3ed0641f49e89b4e420f9eef5d3d5a881) Signed-off-by: Tero Kristo Reviewed-by: Tom Rini Signed-off-by: Tero Kristo

efi_loader: Work-around build issue due to missing hash_calculate()

2021-05-28T14:17:01Z

The hash_calculate() symbol is provided by hash-checksum.c. It depends on hash_progressive_lookup_algo(), provided when CONFIG_HASH=y. The issue is that hash_calculate() is used by the efi_loader, irregardless of CONFIG_FIT_SIGNATURE. As pointed out in commit 87316da05f2f ("lib: introduce HASH_CALCULATE option"), enabling hash_calculate() based on CONFIG_FIT_SIGNATURE is incorrect. To resolve this, use CONFIG_HASH as the compile switch for hash-checksum.c. This ensures that all dependencies are compiled, and is the most natural Kconfig to use. There is the issue of having to 'select HASH' in a couple of places that already 'select SHA256'. This is a deeper problem with how hashes are organized, and fixing it is beyonf the scope of this change. Signed-off-by: Alexandru Gagniuc Acked-by: Masahisa Kojima

Revert "lib: introduce HASH_CALCULATE option"

2021-05-28T14:17:01Z

When we think of Kconfig, we usually think of features that we like to enable or not. Ideally, we wouldn't use Kconfig to fix a build issue, although sometimes it might make sense. With Kconfig it's hard to guarantee that the fix is universal. We can only say that it works for the set of tested configurations. In the majority of cases, it's preferable to let the linker figure things out for us. The reverted commit attempted to fix a build issue by adding an invisible Kconfig option. This is wrong in several ways: It invents a new Kconfig variable when CONFIG_HASH already exists for the same purpose. Second, hash-checksum.c makes use of the hash_progressive_lookup_algo() symbol, which is only provided with CONFIG_HASH, but this dependency was not expressed in the reverted patch. It feels like Kconfig is turning into a listing of all available source files, and a buffet to 'select' which ones to compile. The purpose of this revert is to enable the next change to make use of CONFIG_HASH instead of adding to Kconfig. This reverts commit 87316da05f2fd49d3709275e64ef0c5980366ade.

lib: introduce HASH_CALCULATE option

2021-05-18T10:36:13Z

Build error occurs when CONFIG_EFI_SECURE_BOOT or CONFIG_EFI_CAPSULE_AUTHENTICATE is enabled, because hash-checksum.c is not compiled. Since hash_calculate() implemented in hash-checksum.c can be commonly used aside from FIT image signature verification, this commit itroduces HASH_CALCULATE option to decide if hash-checksum.c shall be compiled.

lib: Rename rsa-checksum.c to hash-checksum.c

2021-04-14T19:06:08Z

rsa-checksum.c sontains the hash_calculate() implementations. Despite the "rsa-" file prefix, this function is useful for other algorithms. To prevent confusion, move this file to lib/, and rename it to hash-checksum.c, to give it a more "generic" feel. Signed-off-by: Alexandru Gagniuc Reviewed-by: Simon Glass

tpm: Switch TPMv1 over to use the new API

Take over the plain 'tpm_...' functions for use by the new TPM API. Rename all the TPMv1 functions so they are called from the API. Update the TPMv1 functions so that they are called from the API. Change existing users to use the tpm1_ prefix so they don't need to go through the API, which might introduce uncertainty. Signed-off-by: Simon Glass Acked-by: Ilias Apalodimas
