sw/stm32 - Cryptech HSM on STM-32 ARM processor

Age	Commit message (Collapse)	Author
2020-05-05	Add more RPC tasks for better signing performance.	Paul Selkirk

2020-03-09	Replace the brutally inefficient fp_to_unsigned_bin with one based on	Paul Selkirk
	fp_read_unsigned_bin. I thought about patching it directly in sw/thirdparty/libtfm, but ultimately decided to keep that pristine (especially since we verify file checksums there).
2020-02-18	timing tests for RSA signingmodexpng	Paul Selkirk

2018-12-05	Tell libtfm that the ARM is little-endian, so it can optimize ↵	Paul Selkirk
	fp_read_unsigned_bin(). This enables some overflow-detection code, which fixes CT-01-009. It also saves 484us/call, which adds up to 6.3ms/RSA signature.
2018-12-03	Re-delete SysTick_hook (commit 9ffead1), which somehow crept back in.	Paul Selkirk

2018-12-02	Clean up the profiling code to the point where I stand a chance of	Paul Selkirk
	understanding it 6 months from now. While I'm at it, try to make it a little more efficient (because 50-60% of time in a typical profiling run is spent in the function-entry counting), and collapse profil.c into gmon.c.
2018-11-26	Add loop unrolling to bring the profilable mem* functions closer to	Paul Selkirk
	newlib, because memset is called a LOT in the course of RSA signing, and we need to understand how much time we're actually spending there.
2018-09-04	Make parsing and display of masterkey values consistent with one another,	Paul Selkirk
	so the user might be able to copy and paste a generated key into the CLI for recovery. Display had been a 32-byte hexdump. Parsing (manual re-entry of the KEK) had been 8 32-bit little-endian values. This has been a pain point for literally two years, albeit at a low enough pain level that I've managed to cringe and ignore it.
2018-05-27	Script to run a test with HSM profiling.	Rob Austein

2018-05-01	Fix mbed vpath not to use explicit (and wrong) paths	Paul Selkirk

2018-04-19	Cleanup: warn of signed/unsigned mismatches in libhal.	Paul Selkirk
	This is from October's cleanup binge, but I forgot to commit it at the time.
2018-04-06	Merge branch 'profiling'	Paul Selkirk

2017-10-11	Cleanup 'unused parameter' warnings, a couple of which are actual coding errors.	Paul Selkirk

2017-10-11	Cleanup: signed/unsigned mismatches, mostly in loop counters	Paul Selkirk

2017-09-21	cleanup	Paul Selkirk

2017-09-07	Rebase branch 'profiling' from master	Paul Selkirk

2017-09-07	Sigh, right offset for the wrong register. Get the PC (the address we	Paul Selkirk
	interrupted) rather than LR (the return address from the function we interrupted). Also, change u_short and u_int to unsigned short and unsigned int, since gcc recently decided that those aren't part of the C99 standard. Finally, add profilable versions of memcpy, memset, and friends, because they get called a lot in the course of unit testing, and it would be nice to know who's calling them.
2017-09-07	Correct offset to get the PC.	Paul Selkirk
	A previous version of this code ran over the RTOS, where threads used the Process Stack, while the SysTick interrupt used the Main Stack. Now everything's on the main stack, so we need to account for 2 extra words that SysTick_Handler pushes on the stack at entry.
2017-09-07	Port profiling code, using a new SysTick hook and new CLI commands.	Paul Selkirk

2017-09-07	Copy profiling code from MCUOnEclipse.	Paul Selkirk

2017-08-31	Withdraw SysTick_hook (commit 9ffead1), because it turns out there was ↵	Paul Selkirk
	already a user-callback mechanism with HAL_SYSTICK_IRQHandler() and HAL_SYSTICK_Callback().
2017-07-31	Add a generic SysTick hook, to call a function on every 1ms tick, because ↵	Paul Selkirk
	it's easier than setting up a dedicated timer.
2017-06-17	Fix optimization settings in HSM's build of libtfm.	Rob Austein

2017-05-04	Copy profiling code from MCUOnEclipse.	Paul Selkirk

2017-04-29	Remove exception handlders that I probably shouldn't have defined in the ↵	Paul Selkirk
	first place.
2017-04-29	Remove rtos source files.	Paul Selkirk

2017-04-17	Use default SysTick interrupt priority.	Paul Selkirk
	We really don't want SysTick_Handler, which runs the task scheduler, to run at a higher priority than SVC_Handler, which runs supposedly-atomic operations like mutex locking and unlocking. I've seen a mutex lock/unlock mismatch which I think is due to interrupting rt_mut_release at a particularly inopportune moment.
2017-04-01	Change RPC UART to have a high-priority thread monitoring a large(ish) DMA	Paul Selkirk
	buffer, because we've observed out-of-order receives under load.
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.
2016-09-01	"make clean" needs to use "rm -f" to avoid gratuitous failures.	Rob Austein

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

2016-07-06	Fix the way code is commented out, to avoid compiler warnings.	Paul Selkirk

2016-07-06	Simplify library Makefiles by using symbols defined in top-level Makefile, ↵	Paul Selkirk
	rather than re-deriving them.
2016-06-25	Split LIB*_DIR into _SRC and _BLD.	Paul Selkirk
	Also rename all instances of GNUmakefile to Makefile.
2016-06-25	Finish unwinding subrepository hairball: VPATH setup.	Rob Austein

2016-06-24	Start unwinding subrepository hairball: remove submodules.	Rob Austein

2016-06-23	Drag in libhal update.	Rob Austein

2016-06-23	Drag submodule updates into sw/stm32.	Rob Austein

2016-06-21	Update sw/stm32 to track recent subrepository commits, since without them it ↵	Rob Austein
	no longer compiles (sigh).
2016-06-14	Pull in sw/libhal CLIENT_TRANSPORT makefile fix.	Rob Austein

2016-06-14	Pull libhal changes into stm32 subrepo.	Rob Austein

2016-06-14	Bring sw/stm32 super-repository up to date with the ten zillion	Rob Austein
	commits which have been made in other repositories since the last time anybody bothered to synchronize this. Poster child for why this kind of recursive hairball belongs in release engineering rather than in source code repositories which are under active development, but that yak can wait a little while longer for its shave.
2016-06-13	Only the HSM project needs the RTOS; most of the test projects can use the ↵	Paul Selkirk
	STM32 HAL code directly.
2016-06-13	Add __end symbols for CCMRAM and SDRAM sections.	Paul Selkirk
	This lets us, say, use these sections for stack or heap.
2016-06-13	SDRAM is for uninitialized data only.	Paul Selkirk
	We don't plan to put initialized data in SDRAM, and we don't have startup code to copy initialized data, so don't even bother. Further, the linker will reserve space in FLASH, even for uninitialized data, so just don't.
2016-06-09	Put thread stack buffers in SDRAM, because pkey uses a lot of stack.	Paul Selkirk
	Also rearchitect the way we handle RPC requests - have a bunch of waiting dispatch threads rather than continually creating and deleting threads.
2016-06-07	fix some comments	Fredrik Thulin
