Age	Commit message (Collapse)	Author
2018-11-14	Add some yields to hal_hashsig_ks_init, so other tasks can run while we're ↵	Paul Selkirk
	rebuilding the hash tree.
2018-08-12	Clean up builds for *BSD/clang.	Paul Selkirk
	Move lm[ot]s_algorithm_t definitions to hal.h, prefix all public symbols with 'hal_'. Remove some unused functions. Wrap hal_pkey_slot_t initializers in an extra set of curly braces. Remove an unused-argument kludge (x=x;) because gcc doesn't care, and clang complains. Make timersub a proper macro. Add some casts to printf arguments, because !@#$ printf formats.
2018-07-24	Change the rest of the hashsig ASN.1 wrapper functions to static inline, for ↵	Paul Selkirk
	consistency.
2018-07-24	A recent(?) version of arm-none-eabi-gcc decided to make storage for enums	Paul Selkirk
	the minimum size necessary, so hal_asn1_decode_lms_algorithm and hal_asn1_decode_lmots_algorithm were writing 4 bytes of data into 1-byte variables. Hilarity ensued. Yes, I already knew that conflating enum with uint32_t was a bad idea, I was just being lazy. For that matter, sizeof(size_t) isn't guaranteed either, although arm-none-eabi-gcc treats it as 32 bits on this 32-bit target (for now), so exercise proper data hygiene in hal_asn1_decode_size_t as well.
2018-07-24	Add protection against trying to use hashsig while the restart mechanism is ↵	Paul Selkirk
	rebuilding the tree.
2018-05-01	Add some yields to try to improve responsiveness during hashsig key ↵	Paul Selkirk
	generation and deletion.
2018-04-19	Reconstruct the hashsig hash tree(s) on device restart.	Paul Selkirk

2018-04-19	Update to draft-10: clarifications and Test Case 2;	Paul Selkirk
	add ability to export public key to xdr for interop testing
2018-04-19	For 2^w and 2^h, replace hard-coded w2 and h2 values with 1<<w and 1<<h.	Paul Selkirk

2018-04-19	Fold the coef* functions into a single function, because that really was ↵	Paul Selkirk
	premature optimization.
2018-04-19	Fix coef4, which was swapping digits	Paul Selkirk

2018-04-19	Implement hash-based signatures, per draft-mcgrew-hash-sigs-08.txt	Paul Selkirk
