2018-05-20Better hal_core_alloc() semantics, assert() and printf() cleanup.Rob Austein
Various fixes extracted from the abandoned(-for-now?) reuse-cores branch, principally: * Change hal_core_alloc*() to support core reuse and to pick the least-recently-used core of a particular type otherwise; * Replace assert() and printf() calls with hal_assert() and hal_log(), respectively. assert() is particularly useless on the HSM, since it sends its error message into hyperspace then hangs the HSM.
2018-01-04Add hal_core_alloc2() to fix a dining philosophers problem in hal_modexp2().Paul Selkirk
Uncoordinated attempts to allocate two modexpa7 cores leads to deadlock if multiple clients try to do concurrent RSA signing operations. The simplest solution (back off and retry) could theoretically lead to resource starvation, but we haven't seen it in actual testing.
2017-12-13Merge branch systolic_crt into master.Rob Austein
This branch was sitting for long enough that master had been through a cleanup pass, so beware of accidental reversions.
2017-10-23Cleanup signed/unsigned mismatches, mostly in loop countersPaul Selkirk
2017-10-11Cleanup: Remove "const" qualifiers from function return types.Paul Selkirk
2017-09-13Preliminary support for parallel core RSA CRT.Rob Austein
2017-05-25Checkpoint while refactoring. Almost certainly will not compile.Rob Austein
2017-04-25adapt to the new experimental tasking systemPaul Selkirk
2017-02-02Add locking around keystore operations.Rob Austein
2016-10-07Stop whining about POSIX strnlen() function.Rob Austein
2016-09-02Code to convert between text and internal forms of UUIDs.Rob Austein
Includes a few cosmetic fixes to address gcc format string warnings and git trailing whitespace warnings.
2016-08-10Reset table of cores, e.g. after resetting FPGA from CLI.Paul Selkirk
2016-08-10Merge branch 'resource_management'Paul Selkirk
2016-07-12Make probe_cores deal with an unconfigured FPGA (and come back later).Paul Selkirk
See, reading from an unconfigured FPGA returns all-1, while reading from empty cores on a configured FPGA returns all-0. The consequence of this is that the HSM was probing the FPGA once on startup, filling its core table with 0xff, rendering the FPGA useless. Along the way, I put the FPGA core table in static memory, rather than malloc'ing it, because that's not so good in an embedded environment. But I kept the linked list, because that at least tells us what to do if HAL_STATIC_CORE_STATE_BLOCKS is 0.
2016-07-06Belatedly adjust hal_io_read/write to the new flat addressing architecture.Paul Selkirk
2016-07-05Attempt to add resource management, for multiple cores of the same type.Paul Selkirk
Find a suitable core, and mark it busy. Don't forget to release it as soon as you're done. This has a knock-on effect of un-const'ing core arguments and struct fields in a lot of places, and it moves some core checks around.
2016-06-14Add support for ModExpA7Paul Selkirk
2015-12-23RPC interface to TRNG and (incomplete) PIN code.Rob Austein
2015-11-14Catch up with other branch merges.Paul Selkirk
- TRNG cores are contiguous (but they still have their own mux, so occupy a block of 16 cores). - Use Rob's updated libhal in my new apps.
2015-10-04Whack libhal API to use current configure_core_selector mechanism.Rob Austein
Compiles, not yet tested.
