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

2021-03-02T20:53:37Z

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

crc32: Exclude crc32 from TPL

2021-01-27T22:03:16Z

Unfortunately the toolchain often brings in the crc32 table even if the function is not actually used. For now, exclude it from the TPL build, which is very sensitive to size. Signed-off-by: Simon Glass

lib: Add getopt

2020-10-30T14:56:11Z

Some commands can get very unweildy if they have too many positional arguments. Adding options makes them easier to read, remember, and understand. This implementation of getopt has been taken from barebox, which has had option support for quite a while. I have made a few modifications to their version, such as the removal of opterr in favor of a separate getopt_silent function. In addition, I have moved all global variables into struct getopt_context. The getopt from barebox also re-orders the arguments passed to it so that non-options are placed last. This allows users to specify options anywhere. For example, `ls -l foo/ -R` would be re-ordered to `ls -l -R foo/` as getopt parsed the options. However, this feature conflicts with the const argv in cmd_tbl->cmd. This was originally added in 54841ab50c ("Make sure that argv[] argument pointers are not modified."). The reason stated in that commit is that hush requires argv to stay unmodified. Has this situation changed? Barebox also uses hush, and does not have this problem. Perhaps we could use their fix? I have assigned maintenance of getopt to Simon Glass, as it is currently only used by the log command. I would also be fine maintaining it. Signed-off-by: Sean Anderson

Add support for SHA384 and SHA512

2020-06-12T17:14:07Z

The current recommendation for best security practice from the US government is to use SHA384 for TOP SECRET [1]. This patch adds support for SHA384 and SHA512 in the hash command, and also allows FIT images to be hashed with these algorithms, and signed with sha384,rsaXXXX and sha512,rsaXXXX The SHA implementation is adapted from the linux kernel implementation.

lib: Allow MD5 to be enabled in SPL

2020-05-15T18:47:35Z

At present the MD5 option cannot be enabled by board configs since it has no Kconfig name. It is generally enabled, so long as FIT support is present. But not all boards use FIT, particularly in SPL Fix this and add an option for SPL as well. This allows board code to call md5() even if FIT support is not enabled. Signed-off-by: Simon Glass
