* imxtools/sbtools: switch SHA1 implementation to Crypto++Amaury Pouly2017-01-16
| | | | | | | 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
* imxtools/sbtools: switch AES implementation to Crypto++Amaury Pouly2017-01-16
| | | | | | | | 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
* imxtools/sbtools: various fixesAmaury Pouly2017-01-16
| | | | | | | Change bug() macro, fix memory leaks, always use -h for help, fix usage(), fix comment, remove useless macro Change-Id: I30554b5e07e6f2845560a570808603cf8c4da5ad
* imxtools/sbtools: rework cryptographyAmaury Pouly2017-01-16
| | | | | | | | | | 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).

* imxtools: correctly read unencrypted images in raw modeAmaury Pouly2017-01-16

* imxtools: rework key/IV overriding logicAmaury Pouly2017-01-16
| | | | | | | 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
* imxtools: rework sb file productionAmaury Pouly2017-01-16
| | | | | | | | | | | | | | | | | | | | 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.

* imxtools: fix bug aes128 (did not update cbc-macp)Amaury Pouly2017-01-01
| | | | | | | 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
* sb1: fix buggy comparisonAmaury Pouly2014-12-20
| | | | | | | | | 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

* sbtools: use default transfer size if it cannot be probedAmaury Pouly2014-09-07
| | | | | | | | 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

* imxtools/sbloader: rewrite hid codeAmaury Pouly2013-10-09
| | | | | | | Rewrite code with proper documentation: it uses a UMS like CBW/CSW to wrap commands and status. Change-Id: I10476c87aaea96d4b9e54f8c1c266835c8e89721
* imxtools/sbtools: always probe report size for HID recovery modeAmaury Pouly2013-10-09
| | | | | | | 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

* sbtools: now generate a db file along with with elf/rsrc filesAmaury Pouly2013-08-22
| | | | | | | | | | 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

* sbtools: fix output printingAmaury Pouly2013-08-06
| | | | | | | The code used printf instead of the provided printf functions, resulting in strange output. Change-Id: I2c7c2531d8d54ecdea97e8c189d18d351320ca7d

* elf: fix handling of virtual/physical addressesAmaury Pouly2013-08-06
| | | | | | | | | | 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.

* imxtools: rewrite sbloader to handle both versions + user friendlyAmaury Pouly2013-06-13
| | | | | | | | | 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

* sbtools: add brute force option for sb1 in sbtoelfAmaury Pouly2013-02-16
| | | | | | | | | | 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.
