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.
2016-08-10Mixed-mode pkey sign and verify must construct DigestInfo for PKCS #1.5.Rob Austein
PKCS #11 expects a DigestInfo rather than a raw digest when passing a pre-computed digest for PKCS #1.5 signature or verification, so the rpc_pkey signature and verification calls do too. This requires special case handling of RSA when the user passes a digest handle in mixed mode. Annoying, but PKCS #1.5 is weird enoug that there's no way to avoid some kind of special case handling, this approach has the advantage of not requiring us to parse and reconstruct the ASN.1, and is probably what PKCS #11 has trained software to expect in any case.
2016-07-07Drop RPC response message if the opcode doesn't match what we sent.Rob Austein
2016-06-30RPC wire format now includes client handle in all requests, and opcode andPaul Selkirk
client handle in all responses. This simplies the daemon a little, and means that the directly-connected serial client uses the same wire format as the daemon. The expense is some redundant code in rpc_client and rpc_server to process (and throw away) this extra stuff.
2016-06-09Fix duplicate dispatch vectors when building for RPC_CLIENT_LOCAL.Rob Austein
2016-05-31Conditionalize "mixed" operations so we can build a clean remote client.Paul Selkirk
Note that mixed mode doesn't actually work, because aes_keywrap tries to hal_io_write to the AES core.

opcode right.
2016-05-15Add hal_rpc_pkey_rename(); allow null string as (temporary) key name.Rob Austein
Temporary nature of null string as key name is not enforced by the keystore code, it's just a convention to allow callers to generate a keypair, obtain the public key, hash that to a Subject Key Identifier (SKI), and rename the key using the SKI as the new name. This is a compromise to let us use SKI-based key names in PKCS #11 while keeping the keystore code simple.

2016-05-14Clean up pkey mixed mode.Rob Austein
2016-05-14Entirely too much fun with C const-ification.Rob Austein
2016-05-14Add mixed-mode key support, for PKCS #11 "session" (ie, not "token") keys.Rob Austein
2016-05-12Fix buffer allocations in RPC client code.Rob Austein
The client wrappers for several RPC calls were not allocating enough space for all of their arguments. Fixed, and added a bit of syntactic sugar to make inspection a bit easier to combat the eyes-glazing-over effect of an entire file full of nearly-identical RPC client stubs.
2016-03-29Enable 'mixed' mode, with client-side hashing.Paul Selkirk
2016-03-16Added serial RPC transport and lots more...Paul Selkirk
Added RPC function to get server version number. Substantially reworked GNUMakefile with conditionals. Renamed rpc_*() and xdr_*() to hal_*() for consistency. Moved hal_io_fmc.c from stm32 repo.

2015-12-24More work on PIN/login/logout code. Access control still missing,Rob Austein
committing now so Paul has a chance to look at the current RPC API.
