2020-02-18timing tests for RSA signingmodexpngPaul Selkirk
2019-04-06Remove fmc_[read|write]_32, since we now memcpy in hal_io_[read|write].Paul Selkirk
2019-04-03Merge branch 'fmc_clk_60mhz' to 'master'Paul Selkirk
2019-03-31Remove inclusion of now-deleted hashsig.hPaul Selkirk
2019-02-28Report SDRAM usage in `task show`Paul Selkirk
2018-12-05Tell 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.
2018-12-03Re-delete SysTick_hook (commit 9ffead1), which somehow crept back in.Paul Selkirk
2018-12-02Clean up the profiling code to the point where I stand a chance ofPaul 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.
2018-11-26Add loop unrolling to bring the profilable mem* functions closer toPaul 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.
2018-11-14Increase cli task, and move it to SDRAM, because main RAM is getting full.Paul Selkirk
2018-09-07Tweak for 60MHz FMC clock.Rob Austein
2018-09-05When erasing the whole keystore, optionally preserve the login PINs.Paul Selkirk
2018-09-04Make 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.
2018-08-27Add startup delay to let fmc bus settlePaul Selkirk
2018-07-25Merge branch 'hashsig'Paul Selkirk
2018-07-24Add dummy hal_free_static_memory to cli-test, to avoid a link error.Paul Selkirk
We really ought to rototill cli-test, but not today.
2018-07-16Whack various bits of sw/stm32 test code to compile on fmc_clk branch.Rob Austein
2018-07-07Changed FMC initialization code to match the new sync FMC arbiter. RemovedPavel V. Shatov (Meister)
unnecessary code (no more double read, yay!)
2018-05-27Script to run a test with HSM profiling.Rob Austein
2018-05-27FMC cleanup: constification, gratuitous pointer.Rob Austein
2018-05-27Convert FMC I/O functions to static inline.Rob Austein
fmc_read_32() and fmc_write_32() get called often enough that it's worth eliminating unnecessary function call overhead.
2018-05-23Simplify FMC I/O code.Rob Austein
We're no longer using a preemptive multitasker, and we're on the Alpha, not the old bridge board, so all we really need to do is read or write one word at a time via a pointer then wait for the GPIO idle pin to light. Well, other than needing to read twice because of a known hardware problem with the STM32. So we dont need to fiddle with IRQ, or use the CMSIS SRAM lock, or....

2018-04-19Rebase hashsig from masterPaul Selkirk
2018-04-19Reconstruct the hashsig hash tree(s) on device restart.Paul Selkirk
This can take long enough (several minutes for h=10) that we do it in a background task, which is then converted to an RPC dispatch task. Also add a very limited form of free(), to free the topmost allocation in the sdram "heap". I don't want to deal with real heap management, but I do want to be able to recover memory upon deleting a hashsig key, if it's easy to do so.
2018-04-19Implement hash-based signatures, per draft-mcgrew-hash-sigs-08.txtPaul Selkirk
2018-04-19Cleanup: 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.

2017-12-14Revert a clean up 'fix' which actually broke FPGA upload.Paul Selkirk
2017-10-17Overhaul UART APIPaul Selkirk
MGMT is the default UART, and no one should have to explicitly refer to the UART unless they need USER (hsm.c:hal_serial_send_char). The default UART is now exposed in the header file, so that the default-using functions can be macros, which saves a few bytes in code space, and a few microseconds in function call overhead.
2017-10-15Cleanup: All drivers return HAL_StatusTypeDef rather than magic values.Paul Selkirk
Note: This affects libhal/ks_token.c, which uses the keystore driver directly.
2017-10-11Cleanup 'unused parameter' warnings, a couple of which are actual coding errors.Paul Selkirk
2017-10-11Cleanup: signed/unsigned mismatches, mostly in loop countersPaul Selkirk

2017-09-07Duh, actually build task_metricsPaul Selkirk
2017-09-07Sigh, right offset for the wrong register. Get the PC (the address wePaul 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.
2017-09-07Correct 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.
