2017-03-02Try 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).
2017-02-23Add --pin and --quiet options.Paul Selkirk
2017-02-23Speed 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.

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.

2016-11-02Wait for WIP to clear before returning from erase operations too.Rob Austein
Wrong-block-type race condition errors went away after adding the WIP check after flash write operations, then came back once (isolated incident) while running a series of tests which had written enough flash blocks that ks_flash may have finally had to erase something rather than just zeroing. Code inspection confirmed that the erase code was not waiting for WIP to clear before exiting. Difficult to prove that this was the cause of an unreproducible failure, but seems like a likely candidate given previous behavior and change should be harmless, so adding it. Timeout for this flag check is 2000 ms, which is what other erase-related WIP flag checks were already using.
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.
2016-11-01Don't return from flash write calls until WIP flag clears.Rob Austein
Absence of this check created a nasty race condition in sw/libhal/ks_flash.c, which didn't show up until we had test code which attempted to delete a long series of keys in quick succession. I'm not aware of any sane reason why we would ever want to skip this check, so it's unconditional and applies to all of the SPI flash code, not just the keystore flash code.

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.

2016-09-02Whack 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.

(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).
