2016-11-15Allow keystore reinitialization without re-allocating static memory.Rob Austein
Wiping the keystore flash requires reinitializing the keystore, but we don't want to allocate new static memory when we do this.
2016-11-14More API cleanup: remove hal_rpc_pkey_list().Rob Austein
hal_rpc_pkey_list() was a simplistic solution that worked when the keystore only supported a handful of keys and we needed a quick temporary solution in time for a workshop. It doesn't handle large numbers of keys well, and while we could fix that, all of its functionality is now available via more robust API functions, so simplifying the API by deleting it seems best. Since this change required mucking with dispatch vectors yet again, it converts them to use C99 "designated initializer" syntax.
2016-11-14hal_rpc_pkey_find() -> hal_rpc_pkey_open().Rob Austein
2016-11-10Clean out huge swacks of RPC API we don't need anymore.Rob Austein
pkey attribute API is now just set_attributes() and get_attributes().
2016-11-08First cut at multi-attribute get/set/delete API.Rob Austein
This is not yet complete, only the ks_volatile driver supports it, ks_flash will be a bit more complicated and isn't written yet. At the moment, this adds a complete duplicate set of {set,get,delete}_attributes() functions in parallel to the earlier {set,get,delete}_attribute() functions. We will almost certainly want to get rid of the duplicates, probably (but not necessarily) the entire single-attribute suite. At the moment, though, we want both sets so we can compare execution speeds of the two sets of functions.
2016-11-01Add hal_rpc_pkey_get_key_curve().Rob Austein
Incidental minor refactoring of hal_rpc_server_dispatch().
2016-10-30Use public RPC API when dispatching from RPC server.Rob Austein
The rpc_server code used to bypass the public API calls by using the RPC dispatch vectors directly, but doing so bypasses various checks for trivial argument errors. It's not safe for the HSM to trust the client to check these, and duplicating the checks in the client and server code is error prone, so the best solution is for the server code to dispatch via the public API, as it was originally designed to do, and not try to micro-optimize the dispatch calls.
2016-10-24Make previous_uuid an input-only argument to hal_rpc_pkey_match().Rob Austein
In retrospect it's obvious that this never needed to be an input/output argument, as its value will always be the same as the last value in the returned array. Doh. So simplify the RPC and call sequence slightly by removing the unnecessary output value.
2016-10-19Shake first round of bugs out of hal_rpc_pkey_match().Rob Austein
The filtering code for this function has not been tested yet.
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.
2016-10-07Fix session handle arguments in RPC calls.Rob Austein
RPC calls which pass a pkey handle don't need to pass a session handle, because the session handle is already in the HSM's pkey slot object; pkey RPC calls which don't pass a pkey argument do need to pass a session handle. This change percolates down to the keystore driver, because only the keystore driver knows whether that particular keystore cares about session handles.
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.
2016-09-11Explicit initialization of keystore drivers instead of guessing.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.
2016-09-01Revised 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.

2016-06-30Merge branch 'master' into macosx.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.
2016-06-30Start work to support client code on Mac OS X.Rob Austein
Includes preliminary support for the magic Mac-specific ioctl() to see line speed, but has not yet been tested, that's waiting for some supporting tweaks to the RPC code from Paul. Includes some general cleanup which isn't really specific to Mac OS X per se but which needed doing and which simplifies adding the Mac code.
2016-06-09Fix duplicate dispatch vectors when building for RPC_CLIENT_LOCAL.Rob Austein
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.

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.
