The main task for this patch series is to add the new feature to abort autobooting via a SHA256 encrypted password. For this, some of the old autobooting related config macros have been moved to Kconfig. This was a bit more complicated, since Kconfig currently apparently doesn't support using escape characters '' as used in printf format strings like "foo %s bar\n". And this is needed for some of these new Kconfig options. So I needed to make some changes to the Kconfig sources as well. If nobody complains about these Kconfig stuff, I'll try to push this into the Linux Kconfig source as well.
There should be no functional change introduced. Please let me know if you find any problems.
Thanks, Stefan
Changes in v3: - Added some Acked-by's / Reviewed-by's - Added additional backslash to the default CONFIG_AUTOBOOT_PROMPT string as this seems to be needed for the parser - Added some Acked-by's / Reviewed-by's - Removed CONFIG_AUTOBOOT_STOP_STR2 and CONFIG_AUTOBOOT_DELAY_STR2 again - Introduced hash_parse_string() to share some code as suggested by Simon - Used hash_block() instead of sha256_csum_wd() as suggested by Simon - Added some Acked-by's / Reviewed-by's
Changes in v2: - AUTOBOOT_STOP_STR_SHA256 is a string and not bool - Add input key length check as suggested by Magnus - Add "constant-length" time compare function as suggested by Magnus
