2017-04-15	Logging implementation for Alpha hardware.	Rob Austein

2017-04-12	Handle race condition while fetching key metadata for display.	Rob Austein
	Fetching a list of keys and all of their metadata isn't an atomic process, nor, probably, should it be, so we need to cope with things like a key being deleted via the RPC interface while we're fetching its metadata for display on the console interface.
2017-04-11	Track API changes on sw/libhal pkcs8 branch.	Rob Austein

2017-03-02	Try to be a bit more robust in the face of normal errors.	Paul Selkirk
	If hal_rpc_server_dispatch() returns an XDR decode error because the request packet was too short, don't call Error_Handler() and kill the dispatch thread, just drop the request. Add more ibuf_queue entries, but don't panic and kill the dispatch thread if we can't get one, just drop the incoming character (which will lead to an XDR decode error if/when we finally get an ibuf).
2017-02-23	Add --pin and --quiet options.	Paul Selkirk

2017-02-23	Speed up file upload enormously.	Paul Selkirk
	We need to start with a long serial timeout, in order to catch the reboot messages for a firmware upload (this has to be done through the bootloader). But once we start sending the file, cut the serial timeout to 1ms. (I've tested it down to 1us, but that may not work for everyone, and it doesn't improve performance in a statistically significant way.) This brings the time to upload a 4.5MB bitstream from 38:23 to 1:25.
2017-02-22	Refactor flash code.	Paul Selkirk

2017-02-21	Use libcli return codes where appropriate; show whether PINs are set.	Paul Selkirk

2017-02-21	Use bulk erase in the one place it makes sense.	Paul Selkirk

2017-02-02	Add locking around keystore operations.	Rob Austein

2016-12-23	Don't wrap key number in "keystore show keys".	Rob Austein

2016-12-21	Rewrite 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.

2016-12-20	Fix bootloader upload callback routine to write the correct number of bytes ↵	Paul Selkirk
	to flash. While we're at it, propagate error returns.

2016-11-14	Track removal of hal_rpc_pkey_list().	Rob Austein

2016-11-14	hal_rpc_pkey_find() -> hal_rpc_pkey_open().	Rob Austein

2016-11-01	Tweak 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.

2016-10-07	Track changes to libhal RPC pkey API.	Rob Austein

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.
2016-09-23	Use subsectors instead of sectors in keystore.	Rob Austein

2016-09-20	Still 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.
2016-09-16	Revised ks_flash. Compiles, not yet tested.	Rob Austein

2016-09-13	Track libhal cleanup (function names, const-ification).	Rob Austein

2016-09-09	Track removal of `type` argument from hal_rpc_pkey_find().	Rob Austein

2016-09-02	Whack 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.
2016-08-23	Show running threads.	Paul Selkirk

2016-08-23	Reset table of cores after resetting FPGA from CLI.	Paul Selkirk

2016-08-23	Multi-client testing revealed race conditions in uart receive code	Paul 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).
2016-08-11	Multiple threads and multiple cores, to deal with multiple clients.	Paul Selkirk

2016-07-21	Use a fresh port of libcli, which retains more of the original API.	Paul Selkirk

2016-07-16	Don't run empty "export" command.	Rob Austein

2016-07-13	'masterkey set' without args sets master key to a random value	Paul Selkirk

2016-07-13	probe_cores() finally does the right thing, so we don't have to call it early.	Paul Selkirk

2016-07-12	Make username a command-line option, default "so" as it used to be.	Rob Austein

2016-07-12	Allow wheel to upload firmware/bitstreams	Paul Selkirk

2016-07-12	Re-disable 'keystore set key'; hexdump binary key names; remove unused ↵	Paul Selkirk
	'show' commands.
2016-07-12	Restore 'keystore set\|rename\|delete' commands; access key by index as well ↵	Paul Selkirk
	as name.
2016-07-09	Clean 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.
2016-07-08	Add 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.
2016-07-07	Merge branch 'master' of https://git.cryptech.is/sw/stm32.git.	Rob Austein

2016-07-07	Add cryptech_miniterm; tweak cryptech_probe to write environment variables ↵	Rob Austein
	like ssh-agent.
2016-07-07	Drop 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.
2016-07-07	Default to one RPC worker thread.	Paul Selkirk
