* Further simplify the rc4 implementation.jsing2025-08-171-117/+45
| | | | | | | | | | | | | | | | The RC4_CHUNK related code is intended to process native word sized chunks if the input and output are naturally aligned. However, RC4_CHUNK is currently a mess of machine dependent defines. Replace this with uint64_t on all architectures - 64 bit architectures will be happy with this and on 32 bit architectures the compiler can decompose this into multiple 32 bit operations. Provide separate rc4_chunk() implementations for big and little endian, since not all architectures have a byte swap instruction that would make this a cheap conversion. Thanks to gkoehler@ and tb@ for testing on big endian. ok tb@

* Add a reasonable ML-KEM API for public use.beck2025-08-1414-897/+1783
| | | | | | | | | | | | | | | Adapt the tests to use this API. This does not yet make the symbols public in Symbols.list which will happen shortly with a bump. This includes some partial rototilling of the non-public interfaces which will be shortly continued when the internal code is deduplicated to not have multiple copies for ML-KEM 768 and ML-KEM 1024 (which is just an artifact of unravelling the boring C++ code). ok jsing@, tb@
* Use faster versions of bignum_{mul,sqr}_{4_8,6_12,8_16}() if possible.jsing2025-08-141-10/+41
| | | | | | | | If ADX instructions are available, use the non-_alt version of s2n-bignum's bignum_{mul,sqr}_{4_8,6_12,8_16}(), which are faster than the _alt non-ADX versions. ok tb@
* Provide amd64 specific versions of bn_mul_comba6() and bn_sqr_comba6().jsing2025-08-142-2/+22
| | | | | | | These use s2n-bignum's bignum_mul_6_12_alt() and bignum_sqr_6_12_alt() functions. ok tb@
* Provide bn_mod_add_words() and bn_mod_sub_words() on amd64.jsing2025-08-142-2/+25
| | | | | | These use s2n-bignum's bignum_modadd() and bignum_modsub() routines. ok tb@
* Add special handling for multiplication and squaring of BNs with six words.jsing2025-08-142-2/+6
| | | | | | | In these cases make use of bn_mul_comba6() or bn_sqr_comba6(), which are faster than the normal path. ok tb@
* Hook additional s2n-bignum routines to the amd64 build.jsing2025-08-141-1/+11
|
* Add CPU feature detection for ADX on amd64.jsing2025-08-142-5/+10
| | | | | | | | Add detection of Multi-Precision Add-Carry Instruction Extensions on amd64. s2n-bignum provides a number of fast multiplication routines that can leverage these instructions. ok tb@
* Clean up parts of rc4.jsing2025-08-141-79/+40
| | | | | | | | | | | | Provide a static inline rc4_step() function that replaces the near identical RC4_STEP and RC4_LOOP macros. Simplify the processing loop and use for loops with small constants, which the compiler can unroll if it wants to do so. Inline the SK_LOOP macro in rc4_set_key_internal(), also using a small loop that the compiler will most likely unroll. ok tb@
* Add benchmarks for 384 bit x 384 bit multiplication and 384 bit squaring.jsing2025-08-121-1/+14

* Bring in bignum_mod{add,sub}() from s2n-bignum.jsing2025-08-122-0/+185
| | | | These provide modular addition and subtraction.
* Bring in bignum_{mul,sqr}_{4_8,8_16}() from s2n-bignum.jsing2025-08-124-0/+877
| | | | | | | These provide fast multiplication and squaring of inputs with 4 words or 8 words, producing an 8 or 16 word result. These versions require the CPU to support ADX instructions, while the _alt versions that have previously been imported do not.
* Bring in bignum_{mul,sqr}_6_12{,_alt}() from s2n-bignum.jsing2025-08-124-0/+807
| | | | | | These provide fast multiplication and squaring of inputs with 6x words, producing a 12 word result. The non-_alt versions require the CPU to support ADX instructions, while the _alt versions do not.
* Add RCS tags.jsing2025-08-122-0/+4
|
* Add const to bignum_*() function calls.jsing2025-08-121-16/+16
| | | | | Now that s2n-bignum has marked various inputs as const, we can do the same. In most cases we were casting away const, which we no longer need to do.
* Sync headers from s2n-bignum.jsing2025-08-122-236/+588
| | | | | This effectively brings in new function prototypes, a chunk of const additions and some new defines.
* Add RCS tags.jsing2025-08-1111-0/+22
|
* Resync s2n-bignum primitives for amd64 with upstream.jsing2025-08-1111-115/+113

* Speed up bn_{mod,sqr}_mul_words() for specific inputs.jsing2025-08-051-3/+25
| | | | | | | | Use bn_{mul,sqr}_comba{4,6,8}() and bn_montgomery_reduce_words() for specific input sizes. This is significantly faster than using bn_montgomery_multiply_words(). ok tb@
* Provide bn_sqr_comba6().jsing2025-08-052-2/+48

* Provide bn_mul_comba6().jsing2025-08-052-2/+63

* Mark the inputs to bn_mul_comba{4,8}() as const.jsing2025-08-053-9/+9
| | | | | | | This makes it consistent with bn_sqr_comba{4,8}() and simplifies an upcoming change. ok tb@

| | | | | | | | | | | | reset on exec as preserving it across exec is not necessary for its original purpose and has security and usability concerns. Many thanks to Ricardo Branco (rbranco (at) suse.de) who did an independent implementation, caught that /dev/fd/* needed to be handled, and provided a port of the illumos test suite. Thanks to tb@ for assistance with that. ok deraadt@
* replace the flockfile backend with a per FILE recursive mutex.dlg2025-08-041-1/+7
| | | | | | | | | | | | | | | the flockfile implementation in thread/rthread_file.c used an external lock, and associated it with the relevant FILE * as needed. this isn't great for a lot of reasons, complexity being the big one, but the straw that broke the camels back is that it uses a single spinlock to coordinate all of this, which in turn generates a lot of sched_yield syscalls. this avoids all the code complexity and the spinlock by just embedding a small __rctmx in every FILE. tested by and ok tb@ jca@ ok claudio@
* Implement constant time EC scalar multiplication.jsing2025-08-031-16/+103
| | | | | | | | | | | | Replace simplistic non-constant time scalar multiplication with a constant time version. This is actually faster since we compute multiples of the point, then double four times and add once. The multiple to add is selected conditionally, ensuring that the access patterns remain the same regardless of value. Inspired by Go's scalar multiplication code. ok tb@
