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.
2016-10-14Keystore attribute code. Not really tested.Rob Austein
Passes PKCS #11 "make test" but nothing uses the new attribute code yet. Refactored some of the flash block update code. Attribute code is annoyingly verbose, might be possible to refactor some of that.
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.
2016-09-30Multi-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).
2016-09-27Add hal_ks_index_replace().Rob Austein
2016-09-23Use subsectors instead of sectors in keystore.Rob Austein
2016-09-16Debug new ks_flash code.Rob Austein
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.
2016-09-12CRC-32 code for use in ks_flash, stm32 DFU, possibly elsewhere.Rob Austein
This is an open source C99 CRC-32 implementation generated by pycrc, see notes in source on copyright status and pycrc options used. crc32.c contains two different implementations of the CRC-32 algorithm with the same API, one optimized for speed, the other optimized for much smaller code space at the expense of speed. We use the fast implementation by default, but maybe the small implementation will be useful, eg, in the bootloader. Remove the extra later if this turns out to have been a waste of time.
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
2016-09-09Simplify 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.
2016-09-08New keystore index internal API. Compiles, not yet integrated or tested.Rob Austein
2016-09-02Code to convert between text and internal forms of UUIDs.Rob Austein
Includes a few cosmetic fixes to address gcc format string warnings and git trailing whitespace warnings.
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.
2016-08-10Mixed-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.

2016-07-01Use environment variables to specify serial device rather than hard-wiring it.Rob Austein
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.

2016-05-24Move htonl to hal_internal.hPaul Selkirk
2016-05-15Tweak keystore API to allow update-in-place, so hal_ks_rename() will work.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.
2016-05-14Add mixed-mode key support, for PKCS #11 "session" (ie, not "token") keys.Rob Austein
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.
