2017-02-22Refactor flash code.Paul Selkirk
2017-02-21Use libcli return codes where appropriate; show whether PINs are set.Paul Selkirk
2017-02-21Use bulk erase in the one place it makes sense.Paul Selkirk
2017-02-02Add locking around keystore operations.Rob Austein
2016-12-23Don't wrap key number in "keystore show keys".Rob Austein
2016-12-21Rewrite core upload loop to simplify and fix race conditions.Rob Austein
The main loop in cryptech_upload:send_file() was much more complicated than necessary, and also contained some hidden assumptions about serial I/O timing which happened to fail on the first two machines I tested. We already had a perfectly good buffered-input function, so rewrote to use that, and simplified control structure in the process. In theory, the new code should work in any environment where the old one did, but this has not yet been confirmed.

2016-11-01Tweak CLI keystore commands for latest libhal RPC keystore API.Rob Austein
Using {-1} as a client handle in the CLI is a kludge, but the new stricter libhal keystore code really wants us to be consistent about this, so as long as any part of the CLI is using client {-1}, it all needs to do so. This still isn't really right, the CLI probably needs a different set of access rules than those which apply to the RPC calls, but I'm deferring that until we know what the "final" (for this branch) version of the RPC API looks like, and have done whatever refactoring might be required in the libhal keystore drivers.

2016-09-27"keystore erase" now clears entire keystore flash.Rob Austein
Now that we're using more than just the first few sectors of the keystore flash, we need a command to clear the whole thing. This is not quite right yet, because it doesn't yet notify libhal's ks_flash driver that the entire content of the flash has been yanked out from under it. In theory, we should be able to erase the entire flash in a single operation using the bulk erase command command (0xC7), but I couldn't get that to do anything (no error reported, no visible effect), so, for now, we erase by sectors.
2016-09-23Use subsectors instead of sectors in keystore.Rob Austein
2016-09-20Still some problem with uart receive under heavy load, so change to a 2-byte ↵Paul Selkirk
receive buffer with half-complete callbacks, and raise the dma priority.
2016-09-16Revised ks_flash. Compiles, not yet tested.Rob Austein
2016-09-13Track libhal cleanup (function names, const-ification).Rob Austein
2016-09-09Track removal of `type` argument from hal_rpc_pkey_find().Rob Austein
2016-09-02Whack with club until working with new keystore API.Rob Austein
Basic stuff like "keystore show keys", "keystore delete key", and the PIN commands all work with the new keystore code. Some of the management commands are still broken. Some of the old management commands were using libhal-internal APIs for which no real equivalent exists anymore. Some of the old management commands were doing things that, um, never could have worked as written.

2016-08-23Reset table of cores after resetting FPGA from CLI.Paul Selkirk
2016-08-23Multi-client testing revealed race conditions in uart receive codePaul Selkirk
(dropped characters, improper handoff of message buffers). Fixed by a) changing the uart receiver from interrupt to DMA mode, and b) replacing the dispatch mutex and rpc semaphore with a mail queue (memory pool + message queue).
2016-08-11Multiple threads and multiple cores, to deal with multiple clients.Paul Selkirk

2016-07-09Clean up the CLI.Fredrik Thulin
A lot of the commands were just useful when testing/implementing features for the Alpha. Remove them now that they have been merged to projects/cli-test.
2016-07-08Add upload from firmware tarball, gussie up command parser, add dire warnings.Rob Austein
Command parser now enforces little things like mutually-exclusive required options so we warn users who attempt something silly. Preferred source for uploads is now the firmware tarball installed along with the client software; we still support uploading from an explictly-specified source file, but one must now say "-i file". Updating the bootloader is dangerous, we now say so and also require an additional option before we'll even attempt it. For the record, while testing this I did manage to brick my Alpha and had to use an ST-LINK to recover, exactly as predicted by the new dire warning.

like ssh-agent.
2016-07-07Drop bad request packets.Paul Selkirk
Also, if the UART receive callback fails to re-enable receive (because dispatch_thread is in the middle of transmitting a response), signal dispatch_thread to re-enable receive after it's done.
