2017-01-16imxtools/sbtools: switch SHA1 implementation to Crypto++Amaury Pouly
The current implementation was custom and super slow. Since we use Crypto++ anyway, we might as well get use a good implementation. Change-Id: I761ad7401653471e54000e1c2bc3d9882378112f
2017-01-16imxtools/sbtools: switch AES implementation to Crypto++Amaury Pouly
Instead of having our own copy of the AES code, use a good library to do that. Crypto++ is well-maintained, supports a lot of ciphers, works on many OSes, and is optimized for many architectures. Change-Id: I7d7d24b47993206d7338c5f9bac8bbdd3915a667

Change bug() macro, fix memory leaks, always use -h for help, fix usage(), fix comment, remove useless macro Change-Id: I30554b5e07e6f2845560a570808603cf8c4da5ad
2017-01-16imxtools/sbtools: rework cryptographyAmaury Pouly
It was a mess, a mix of crypto_* and cbc_mac calls. I made everything call crypto functions, and also separate key setup from cryptographic operations, this will be useful to speed up the code in the upcoming commits. Drop support for "usbotp" key, since the crypto code for that was never mainlined and we can always get the keys from a device as long as we have code execution (using the DCP debug registers).

2017-01-16imxtools: correctly read unencrypted images in raw modeAmaury Pouly

2017-01-16imxtools: rework key/IV overriding logicAmaury Pouly
The overriding of the IV and real key should be the exception, there is no need to manually set them to false. Change-Id: Id66754f20a79aa5c1a991839345d1242e0aa587d
2017-01-16imxtools: rework sb file productionAmaury Pouly
The old code had some annoying way of dealing with padding by adding explicit instructions to the stream, which is 1) ugly 2) not in par with freescale tools. The trick, which this new version implements, is to put the useful length of the section in the section header, and the actual (with padding) length in the boot tag. This way the tools can just ignore padding instruction by reading the section header, and the bootloader can still load the image because it uses the boot tags. Also correctly handle the case where the first section does not start right after the header (there is a bug in freescale tools for this case by the way). There is an ambiguity in the way the padding instructions should be encrypted: the bootloader should logically treat them as regular instruction of the section stream, but it appears the freescale tools do not generate them as part of the stream and instead encrypt them like boot tags, which is stupid because there is no way the bootloader could decrypt them, and anyway we don't care because the bootloader doesn't decrypt them at all.

2017-01-01imxtools: fix bug aes128 (did not update cbc-macp)Amaury Pouly
Although this does bug is never triggered because we never decrypt and use the resulting CBC-MAC, it's a major overlook. Change-Id: I3c5d318e6428d528483bf888ea284e9ded3889f0
2014-12-20sb1: fix buggy comparisonAmaury Pouly
cppcheck reported: [rockbox/utils/imxtools/sbtools/sb1.c:440]: (warning) Comparison of a boolean expression with an integer other than 0 or 1. Thanks to Thomas Jarosch Change-Id: I0078232706d4014a1f2acea310a7a0d0edf7788b

2014-09-07sbtools: use default transfer size if it cannot be probedAmaury Pouly
A older commit removed this ability but it tends to be a problem since the HID driver can prevent probing of transfer size which then needs to be entered by hand on the command line. Change-Id: Ie5a556ffdcc2adec0e1c984810983e19136b6473

2013-10-09imxtools/sbloader: rewrite hid codeAmaury Pouly
Rewrite code with proper documentation: it uses a UMS like CBW/CSW to wrap commands and status. Change-Id: I10476c87aaea96d4b9e54f8c1c266835c8e89721
2013-10-09imxtools/sbtools: always probe report size for HID recovery modeAmaury Pouly
Some older versions of the ROM (TA3 for example), use a 64 byte report size instead of 1024, so hardcoding 1024 is just a bad idea. Change-Id: I720c4465cfe2f519bffa307175614bba58766dce

2013-08-22sbtools: now generate a db file along with with elf/rsrc filesAmaury Pouly
Now always generate a "make.db" file which aims at being the exact representation of the file, ie running sbtoelf and elftosb using the generated command file should produce the exact same file (except for the random paddings). We still miss the support for some option parsing to achieve that though. Change-Id: Ib7d6b241f7855fd35225df8ab8e0711f69d9ee5a

2013-08-06elf: fix handling of virtual/physical addressesAmaury Pouly
Remove the hackish elf_translate_addresses which should not have existed in the first place, on write always compute the physical address of a section using elf_translate_virtual_address which makes it possible to specify any virtual to physical mapping and fail nicely if there is none.

2013-06-13imxtools: rewrite sbloader to handle both versions + user friendlyAmaury Pouly
The tool can now load sb1 and sb files to devices. Detection has been improved and the tool can infer the packet size for the HID description as well. The command line interface has been vastly improved too, this breaks the old one. Change-Id: I01a0ff8f8a007514aa81c56f114c0f0a86e3303c

2013-02-16sbtools: add brute force option for sb1 in sbtoelfAmaury Pouly
After some reverse engineering, it appears that the keys of the sb1 format are very weak: the 128 bytes are generated from the laserfuse words 4,5 and 6 but in a weird manner: 4 and 5 are simply ORed and 6 is only half used (somehow), making it "only" a 48 bit word to find.
