| | | | | | | | | | | | | | | | | | | | | | | | To test implementations that use TEE keymaster with EARLY_BOOT_ONLY keys, it is required that the "earlyBootEnded" call in vold should be removed before they will pass. Mark those tests as DISABLED_... and include a comment and README indicating what needs to be done.

| * Update the current API dumpJiyong Park2020-03-301-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All aidl_interface modules should by default considered as stable, in case it is used across system and vendor partitions, or across modules. Like other API surfaces, we need to have a dump for the current (yet-to-be-released) version and update it when there is an API change. This is done via . Then the owner of the interface can freeze the current version as a numbered version via . This change shal be rejected only when the owner is certain that the interface is not used across the updatable boundaries. Bug: 152655547 Test: m Change-Id: If899eb8ea77a20b0c097c61abe5bdab64cd6f487
* | use vector<uint8_t> for byte[] in AIDLJooyung Han2020-03-232-7/+5
|/ | | | | | | | | | | | | | | | In native world, byte stream is typically represented in uint8_t[] or vector<uint8_t>. C++ backend already generates that way. This change involves NDK backend. Now NDK backend also uses vector<uint8_t> just like C++ backend.

| | | | | | | | | | | | | We now allow this device to change names to accomodate other board types that use pmem. Setting this in the HAL .rc file now causes SELinux errors on those platforms.

| * Transpose the encoding matrixPaul Crowley2019-12-203-204/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stripe together the encodings from each of the 16 codewords, so that if a 512-byte DRAM line is knocked out, it affects 256 bits from each codeword rather than 4096 bits from a single encoded codeword. Rather than using std::bitset, we directly set and read bits in the std::vector<uint8_t>, because the striping means that copying it will now cost not4k in allocation but 64k. Decode directly to a word, without using list decoding. It seems we don't need list decoding for the error rates that matter here, and we never completed the implementation of it anyway. Declare and test only the full interface, now that it doesn't decompose quite so neatly. Bug: 63928581 Test: atest HadamardTest Change-Id: If022d3f4a8d6fccdf68119d4666f83ce5005bccb
* | Resume on Reboot default implementationKenny Root2019-12-196-0/+202
|/ | | | | | | | | | | | | | | | | A default implementation of the RebootEscrow HAL which relies on RAM retention to keep a key around during a reboot to apply an OTA. This should work on devices that use a "warm reboot" and most likely will work on devices that use a "cold reboot" as well. DRAM will retain information for several seconds depending on the temperature and other factors. This is enough to survive a reboot. With the Hadamard code used in this change for error recovery, many errors can be recovered.

* Add hadamard utilities to encode keysTianjie Xu2019-12-184-0/+392
| | | | | | | | | | | Add the utility functions to encode & decode 32 bytes keys. The hadamard encoding will expand a 2 bytes word to 2^15 bits. And thus the 32 byte key will expand to 64KiB in space. The encoded value is more robust and we will be able to recover the key even if there is some corruption.
