sw/libhal - Cryptech libhal: crypto software, HSM management, RPC

Age	Commit message (Collapse)	Author
2021-06-28	weakref.WeakValueDictionary (at least in Python 3, at least at this moment	Paul Selkirk
	in time, at least on this platform) is sometimes overly aggressive about garbage collecting, including some things that are not garbage. Replace it with a regular dict, and have RPCIOStream.rpc_input manage both adding and removing queues.

2020-05-26	Wow, python-version-independent hexadecimal is painful	Rob Austein

2020-05-25	Untested conversion to support Python 3	Rob Austein

2018-11-01	Tornado 5.0 made an incompatible API change in iostream.BaseIOStream.	Paul Selkirk
	Found when upgrading Ubuntu to 18.10.
2018-07-15	Support PF_UNIX socket inode modes other than 0600.	Rob Austein

2017-05-31	Automatic logout when client disconnects or muxd restarts.	Rob Austein
	The HSM itself should be detecting carrier drop on its RPC port, but I haven't figured out where the DCD bit is hiding in the STM32 UART API, and the muxd has to be involved in this in any case, since only the muxd knows when an individual client connection has dropped. So, for the moment, we handle all of this in the muxd.
2017-05-03	Tweak PySerial write_timeout setting.	Rob Austein

2017-04-26	Don't intefere with sys.exit().	Rob Austein

2017-04-23	Log exit conditions	Rob Austein

2017-04-15	Write to console socket and console log in parallel.	Rob Austein
	We're using non-blocking I/O in any case, might as well take advantage of it to keep console output a little smoother.
2017-04-15	Add console log support to muxd.	Rob Austein

2017-04-11	Log packet drops.	Rob Austein

2017-04-11	Reject malformed messages from RPC UART, not just too-short ones.	Rob Austein

2017-03-06	Debugging code to track message flow.	Rob Austein

2017-01-12	Probing wants a brief delay after probe string on some machines.	Rob Austein
	Probably reached the point of diminishing returns for trying to get probing to work better. Best option, where practical, is to avoid probing completely; when necessary, best run it once then avoid repeating it. cryptech_muxd will probe if requested, but probing is never going to be reliable. Dedicated VID:PID would be much better.
2017-01-12	Finish logging code, skip initialization for missing devices.	Rob Austein

2017-01-11	Cleanup.	Rob Austein

2017-01-11	Add internal port probing code (like running cryptech_probe first).	Rob Austein
	Internal probe code mostly works, probably about as well as cryptech_probe ever did, but almost certainly needs timeouts around its I/O calls, and perhaps additional error handling. At the moment, it works except when it doesn't, just like cryptech_probe. Some day we'll get away from this kludge, but not today.
2017-01-10	Handle connection close events properly, use logging library.	Rob Austein

2017-01-05	Whack multiplexer to handle console too.	Rob Austein
	Renamed multiplexer to cryptech_muxd, since it now handles both RPC and CTY. Added new program cryptech_console to act as client for CTY multiplexer. Might want to add console logging capability eventually, not today. Probably want to incorporate UART probing (what cryptech_probe does now) eventually, also not today.
