* Update BLAKE3 for using the new impl handlingTino Reichardt2023-03-021-22/+4
| | | | | | | | | | | This commit changes the BLAKE3 implementation handling and also the calls to it from the ztest command. Tested-by: Rich Ercolani <[email protected]> Tested-by: Sebastian Gottschall <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Tino Reichardt <[email protected]> Closes #13741
* Fix BLAKE3 tuneable and module loading on Linux and FreeBSDTino Reichardt2022-09-161-13/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apply similar options to BLAKE3 as it is done for zfs_fletcher_4_impl. The zfs module parameter on Linux changes from icp_blake3_impl to zfs_blake3_impl. You can check and set it on Linux via sysfs like this: ``` [bash]# cat /sys/module/zfs/parameters/zfs_blake3_impl cycle [fastest] generic sse2 sse41 avx2 [bash]# echo sse2 > /sys/module/zfs/parameters/zfs_blake3_impl [bash]# cat /sys/module/zfs/parameters/zfs_blake3_impl cycle fastest generic [sse2] sse41 avx2 ``` The modprobe module parameters may also be used now: ``` [bash]# modprobe zfs zfs_blake3_impl=sse41 [bash]# cat /sys/module/zfs/parameters/zfs_blake3_impl cycle fastest generic sse2 [sse41] avx2 ``` On FreeBSD the BLAKE3 implementation can be set via sysctl like this: ``` [bsd]# sysctl vfs.zfs.blake3_impl vfs.zfs.blake3_impl: cycle [fastest] generic sse2 sse41 avx2 [bsd]# sysctl vfs.zfs.blake3_impl=sse2 vfs.zfs.blake3_impl: cycle [fastest] generic sse2 sse41 avx2 \ -> cycle fastest generic [sse2] sse41 avx2 ``` This commit changes also some Blake3 internals like these: - blake3_impl_ops_t was renamed to blake3_ops_t - all functions are named blake3_impl_NAME() now Reviewed-by: Brian Behlendorf <[email protected]> Reviewed-by: Ryan Moeller <[email protected]> Co-authored-by: Ryan Moeller <[email protected]> Signed-off-by: Tino Reichardt <[email protected]> Closes #13725

* Fix memory allocation issue for BLAKE3 contextTino Reichardt2022-06-211-0/+5
| | | | | | | | | | The kmem_alloc(sizeof (*ctx), KM_NOSLEEP) call on FreeBSD can't be used in this code segment. Work around this by pre-allocating a percpu context array for later use.

* Introduce BLAKE3 checksums as an OpenZFS featureTino Reichardt2022-06-081-0/+120
This commit adds BLAKE3 checksums to OpenZFS, it has similar performance to Edon-R, but without the caveats around the latter. Homepage of BLAKE3: https://github.com/BLAKE3-team/BLAKE3 Wikipedia: https://en.wikipedia.org/wiki/BLAKE_(hash_function)#BLAKE3 Short description of Wikipedia: BLAKE3 is a cryptographic hash function based on Bao and BLAKE2, created by Jack O'Connor, Jean-Philippe Aumasson, Samuel Neves, and Zooko Wilcox-O'Hearn. It was announced on January 9, 2020, at Real World Crypto. BLAKE3 is a single algorithm with many desirable features (parallelism, XOF, KDF, PRF and MAC), in contrast to BLAKE and BLAKE2, which are algorithm families with multiple variants. BLAKE3 has a binary tree structure, so it supports a practically unlimited degree of parallelism (both SIMD and multithreading) given enough input. The official Rust and C implementations are dual-licensed as public domain (CC0) and the Apache License. Along with adding the BLAKE3 hash into the OpenZFS infrastructure a new benchmarking file called chksum_bench was introduced. When read it reports the speed of the available checksum functions. On Linux: cat /proc/spl/kstat/zfs/chksum_bench On FreeBSD: sysctl kstat.zfs.misc.chksum_bench This is an example output of an i3-1005G1 test system with Debian 11: implementation 1k 4k 16k 64k 256k 1m 4m edonr-generic 1196 1602 1761 1749 1762 1759 1751 skein-generic 546 591 608 615 619 612 616 sha256-generic 240 300 316 314 304 285 276 sha512-generic 353 441 467 476 472 467 426 blake3-generic 308 313 313 313 312 313 312 blake3-sse2 402 1289 1423 1446 1432 1458 1413 blake3-sse41 427 1470 1625 1704 1679 1607 1629 blake3-avx2 428 1920 3095 3343 3356 3318 3204 blake3-avx512 473 2687 4905 5836 5844 5643 5374 Output on Debian 5.10.0-10-amd64 system: (Ryzen 7 5800X) implementation 1k 4k 16k 64k 256k 1m 4m edonr-generic 1840 2458 2665 2719 2711 2723 2693 skein-generic 870 966 996 992 1003 1005 1009 sha256-generic 415 442 453 455 457 457 457 sha512-generic 608 690 711 718 719 720 721 blake3-generic 301 313 311 309 309 310 310 blake3-sse2 343 1865 2124 2188 2180 2181 2186 blake3-sse41 364 2091 2396 2509 2463 2482 2488 blake3-avx2 365 2590 4399 4971 4915 4802 4764 Output on Debian 5.10.0-9-powerpc64le system: (POWER 9) implementation 1k 4k 16k 64k 256k 1m 4m edonr-generic 1213 1703 1889 1918 1957 1902 1907 skein-generic 434 492 520 522 511 525 525 sha256-generic 167 183 187 188 188 187 188 sha512-generic 186 216 222 221 225 224 224 blake3-generic 153 152 154 153 151 153 153 blake3-sse2 391 1170 1366 1406 1428 1426 1414 blake3-sse41 352 1049 1212 1174 1262 1258 1259 Output on Debian 5.10.0-11-arm64 system: (Pi400) implementation 1k 4k 16k 64k 256k 1m 4m edonr-generic 487 603 629 639 643 641 641 skein-generic 271 299 303 308 309 309 307 sha256-generic 117 127 128 130 130 129 130 sha512-generic 145 165 170 172 173 174 175 blake3-generic 81 29 71 89 89 89 89 blake3-sse2 112 323 368 379 380 371 374 blake3-sse41 101 315 357 368 369 364 360 Structurally, the new code is mainly split into these parts: - 1x cross platform generic c variant: blake3_generic.c - 4x assembly for X86-64 (SSE2, SSE4.1, AVX2, AVX512) - 2x assembly for ARMv8 (NEON converted from SSE2) - 2x assembly for PPC64-LE (POWER8 converted from SSE2) - one file for switching between the implementations Note the PPC64 assembly requires the VSX instruction set and the kfpu_begin() / kfpu_end() calls on PowerPC were updated accordingly.
