2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini6-14/+8
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-10-03include: Add a variadic macro to call a callback for all argumentsMarek Behún1-0/+59
Add a header variadic-macro.h which defines the CALL_MACRO_FOR_EACH marco. This macro can be used as follows: #define TEST(x) CALL_MACRO_FOR_EACH(TEST, a, b, c, d) This will expand to TEST(a) TEST(b) TEST(c) TEST(d) The nice thing is that CALL_MACRO_FOR_EACH is a variadic macro, thus the number of arguments can vary (although it has an upper limit - in this implementation 32 arguments).

2016-11-21rsa: Verify RSA padding programaticallyAndrew Duda3-4/+6
Padding verification was done against static SHA/RSA pair arrays which take up a lot of static memory, are mostly 0xff, and cannot be reused for additional SHA/RSA pairings. The padding can be easily computed according to PKCS#1v2.1 as: EM = 0x00 || 0x01 || PS || 0x00 || T where PS is (emLen - tLen - 3) octets of 0xff and T is DER encoding of the hash. Store DER prefix in checksum_algo and create rsa_verify_padding function to handle verification of a message for any SHA/RSA pairing.

2016-03-15Kconfig: Move CONFIG_FIT and related options to KconfigSimon Glass1-0/+2
There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

Currently the hash functions used in RSA are called directly from the sha1 and sha256 libraries. Change the RSA checksum library to use the progressive hash API's registered with struct hash_algo. This will allow the checksum library to use the hardware accelerated progressive hash API's once available.

2015-01-30rsa: Split the rsa-verify to separate the modular exponentiationRuchika Gupta1-0/+43
Public exponentiation which is required in rsa verify functionality is tightly integrated with verification code in rsa_verify.c. The patch splits the file into twp separating the modular exponentiation. 1. rsa-verify.c - The file parses device tree keys node to fill a keyprop structure. The keyprop structure can then be converted to implementation specific format. (struct rsa_pub_key for sw implementation) - The parsed device tree node is then passed to a generic rsa_mod_exp function. 2. rsa-mod-exp.c Move the software specific functions related to modular exponentiation from rsa-verify.c to this file.

2014-08-09Implement generalised RSA public exponents for verified bootMichael van der Westhuizen1-0/+1
Remove the verified boot limitation that only allows a single RSA public exponent of 65537 (F4). This change allows use with existing PKI infrastructure and has been tested with HSM-based PKI. Change the configuration OF tree format to store the RSA public exponent as a 64 bit integer and implement backward compatibility for verified boot configuration trees without this extra field. Parameterise vboot_test.sh to test different public exponents. Mathematics and other hard work by Andrew Bott.

2014-06-19includes: move openssl headers to include/u-bootJeroen Hofstee4-0/+281
commit 18b06652cd "tools: include u-boot version of sha256.h" unconditionally forced the sha256.h from u-boot to be used for tools instead of the host version. This is fragile though as it will also include the host version. Therefore move it to include/u-boot to join u-boot/md5.h etc which were renamed for the same reason. cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

2013-03-01Roll crc32 into hash infrastructureSimon Glass1-0/+11
Add the CRC32 algorithm to the list of available hashes, and make the crc32 command use hash_command(). Add a new crc32_wd_buf() to make this possible, which puts its result in a buffer rather than returning it as a 32-bit value. Note: For some boards the hash command is not enabled, neither are sha1, sha256 or the verify option. In this case the full hash implementation adds about 500 bytes of overhead. So as a special case, we use #ifdef to select very simple bahaviour in that case. The justification for this is that it is currently a very common case (virtually all boards enable crc32 but only some enable more advanced features). Signed-off-by: Simon Glass <sjg@chromium.org>

2009-08-24start a linker script helper fileMike Frysinger1-0/+25
Start a common header file for common linker script code (such as workarounds for older linkers) rather than doing this in the build system. As fallout, we no longer execute the linker every time config.mk is included by a build file (which can easily be 70+ times), but rather only execute it once. This also fixes a bug in the major version checking by creating a macro to easily compare versions and keep people from making the same common mistake (forgetting to check major and minor together).
