8b4684afcde3930eb49490f0b8431c4cb2ad9a46 - lib/libmd: add optimised SHA1 implementations for amd64

Tue, 28 May 2024 17:20:41 +0200

lib/libmd: add optimised SHA1 implementations for amd64Three implementations are provided: one using just scalarinstructions, one using AVX2, and one using the SHA instructions(SHANI). The AVX2 version uses a complicated multi-block carryscheme described in an Intel whitepaper; the code wascarefully transcribed from the implementatio shipped with theGo runtime. The performance is quite good.

libmd, kern, stand: consolidate md5 implementations (NFC)Reduce the number of md5c.c between the three of these from two to oneby just reaching into the kernel build for both userland builds. Theprecedent for this already exists for sha2 in both cases._libmd_ symbol privatization bits have been moved to sys/md5.h andmd5.h remains to #include for compatibility.This stops exporting MD5Pad() in the process because the kernel stoppedexporting it in 502a35d60f4c. soversion is bumped accordingly.This also renames the libc version of stack_protector.c; it previouslyonly worked by coincidence because .PATH ordering worked out such thatwe got the right one, but this is not the case anymore.

libmd: add dependency workaround for r366344r366344 fixed and reenabled the assembly optimized skein implementation,but skein_block objects were not being rebuilt in no-clean builds. Thisresulted in failing no-clean builds. SKEIN_USE_ASM controls whichroutines come from C vs assembly, and with no explicit dependencyr366344's change to SKEIN_USE_ASM did not cause skein_block.{o,pico}to be rebuilt.Add a dependency on this Makefile for the skein_block objects. Thisdependency is broader in scope than absolutely required (that is, theskein_block objects will now be rebuilt on any change to this Makefile).There are ways this could be addressed, but it is probably not worth theadditional effort or testing time to pursue them.PR: 248221Reported by: kevans, Jeremy FaulknerDiscussed with: kevansSponsored by: The FreeBSD Foundation List of files: /freebsd/lib/libmd/Makefile
