2016-10-09Per-session objects in ks_volatile; more untested ks_attribute code.Rob Austein
Mostly this is another checkpoint (still passes PKCS #11 "make test"). ks_volatile.c now contains support for per-session object visibility; this may need more work to support things like a CLI view of all objects regardless of session. Adding this required minor changes to the keystore and pkey APIs, mostly because sessions are per-client. ks_volatile.c also contains an untested first cut at attribute support. Attribute support in ks_flash.c still under construction.
2016-10-07Checkpoint along the way to adding keystore attribute support.Rob Austein
This is mostly to archive a commit where PKCS #11 "make test" still works after converting the ks_volatile code to use SDRAM allocated at startup instead of (large) static variables. The attribute code itself is incomplete at this point.
2016-09-30Multi-block object support in keystore.Rob Austein
The main reason for supporting multi-block objects is to allow the PKCS #11 code to attach more attributes than will fit comfortably in a single flash block. This may turn out to be unnecessary once we've fleshed out the attribute storage and retrieval code; if so, we can simplify the code, but this way the keystore won't impose arbitrary (and somewhat inscrutable) size limits on PKCS #11 attributes for large keys. This snapshot passes light testing (PKCS #11 "make test" runs), but the tombstone recovery code in ks_init() is a bit involved, and needs more testing with simulated failures (probably induced under GDB).
2016-09-16Revised ks_flash. Compiles, not yet tested.Rob Austein
2016-09-13Cleanup prior to rewriting ks_flash.c.Rob Austein
Whack masterkey code to meet libhal coding standards, such as they are. Started layout of new ks_flash data structures but no changes to functions or flash usage yet. MKM initialization from flash placed under compile-time conditional with warning because it's a dangerous kludge that should go away. Started getting rid of obsolete keystore code; ks_mmap.c kept for now, until I get around to merging the useful bits into ks_volatile.
2016-09-12Doh, allow keystore reinitialization after unclean reboot.Rob Austein
2016-09-11Explicit initialization of keystore drivers instead of guessing.Rob Austein
2016-09-09Rewrite ks_volatile driver to use new ks_index infrastructure.Rob Austein
2016-09-09Missed a few instances of type-based key naming in keystore drivers.Rob Austein
2016-09-09Simplify hal_rpc_pkey_find() by removing `type` argument.Rob Austein
Now that key names are UUIDs generated by the HSM, there's no real need to specify type key type when looking up a key, and removing the `type` argument allows a few simplifications of both the internal keystore API and of client code calling the public RPC API.
2016-09-01Move in-memory keystore from client to server. Whack with club until compiles.Rob Austein
Fixes for various minor issues found while integrating with sw/stm32. Moving the in-memory keystore (PKCS #11 session objects, etc) from the client library to the HSM was on the near term to-do list in any case, doing it now turned out to be the easiest way to solve one of the build problems.
2016-09-01Revised keystore API, part one. Not usable yet.Rob Austein
Changes to implement a revised keystore API. This code probably won't even compile properly yet, and almost certainly will not run, but most of the expected changes are complete at this point. Main points: * Key names are now UUIDs, and are generated by the HSM, not the client. * Keystore API no longer assumes that key database is resident in memory (original API was written on the assumption that the keystore flash would be mapped into the HSM CPU's address space, but apparently the board and flash drivers don't really support that). A few other changes have probably crept in, but the bulk of this changeset is just following through implications of the above, some of which percolate all the way back to the public RPC API.
2016-05-15Tweak keystore API to allow update-in-place, so hal_ks_rename() will work.Rob Austein
2016-03-11First round of debugging based on RPC pkey tests: mostly ASN.1Rob Austein
silliness, with a bit of PKCS #1.5 padding silliness for desert.
2016-03-03Initial implementations of ks_get_kek(). Untested, and none of theseRob Austein
are secure (the one in ks_flash.c is a stub, and the others are for cases where we have no secure hardware in which to store the KEK). These are primarily for testing, since in the long run the entire software implementation of AES-keywrap will be replaced by Verilog which never lets software see the unwrapped key. Or so says current theory. For the moment, we just need something that will let us test the rest of the RPC and keystore mechanisms.
