From 27594eeae6f40a402bc3110f06d57975168e74e3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Parm=C3=A9nides=20GV?= Date: Thu, 4 Jun 2015 19:20:15 +0200 Subject: ics-openvpn as a submodule! beautiful ics-openvpn is now officially on GitHub, and they track openssl and openvpn as submodules, so it's easier to update everything. Just a git submodule update --recursive. I've also set up soft links to native modules from ics-openvpn in app, so that we don't copy files in Gradle (which was causing problems with the submodules .git* files, not being copied). That makes the repo cleaner. --- app/openssl/crypto/aes/asm/aesni-x86_64.pl | 3071 ---------------------------- 1 file changed, 3071 deletions(-) delete mode 100644 app/openssl/crypto/aes/asm/aesni-x86_64.pl (limited to 'app/openssl/crypto/aes/asm/aesni-x86_64.pl') diff --git a/app/openssl/crypto/aes/asm/aesni-x86_64.pl b/app/openssl/crypto/aes/asm/aesni-x86_64.pl deleted file mode 100644 index c9270dfd..00000000 --- a/app/openssl/crypto/aes/asm/aesni-x86_64.pl +++ /dev/null @@ -1,3071 +0,0 @@ -#!/usr/bin/env perl -# -# ==================================================================== -# Written by Andy Polyakov for the OpenSSL -# project.

All above results are consistently better. This -# module also provides better performance for block sizes smaller than -# 128 bytes in points *not* represented in the above table. -# -# Looking at the results for 8-KB buffer. -# -# CFB and OFB results are far from the limit, because implementation -# uses "generic" CRYPTO_[c|o]fb128_encrypt interfaces relying on -# single-block aesni_encrypt, which is not the most optimal way to go. -# CBC encrypt result is unexpectedly high and there is no documented -# explanation for it. Seemingly there is a small penalty for feeding -# the result back to AES unit the way it's done in CBC mode. There is -# nothing one can do and the result appears optimal. CCM result is -# identical to CBC, because CBC-MAC is essentially CBC encrypt without -# saving output. CCM CTR "stays invisible," because it's neatly -# interleaved wih CBC-MAC. This provides ~30% improvement over -# "straghtforward" CCM implementation with CTR and CBC-MAC performed -# disjointly. Parallelizable modes practically achieve the theoretical -# limit. -# -# Looking at how results vary with buffer size. -# -# Curves are practically saturated at 1-KB buffer size. In most cases -# "256-byte" performance is >95%, and "64-byte" is ~90% of "8-KB" one. -# CTR curve doesn't follow this pattern and is "slowest" changing one -# with "256-byte" result being 87% of "8-KB." This is because overhead -# in CTR mode is most computationally intensive. Small-block CCM -# decrypt is slower than encrypt, because first CTR and last CBC-MAC -# iterations can't be interleaved. -# -# Results for 192- and 256-bit keys. -# -# EVP-free results were observed to scale perfectly with number of -# rounds for larger block sizes, i.e. 192-bit result being 10/12 times -# lower and 256-bit one - 10/14. Well, in CBC encrypt case differences -# are a tad smaller, because the above mentioned penalty biases all -# results by same constant value. In similar way function call -# overhead affects small-block performance, as well as OFB and CFB -# results. Differences are not large, most common coefficients are -# 10/11.7 and 10/13.4 (as opposite to 10/12.0 and 10/14.0), but one -# observe even 10/11.2 and 10/12.4 (CTR, OFB, CFB)... - -# January 2011 -# -# While Westmere processor features 6 cycles latency for aes[enc|dec] -# instructions, which can be scheduled every second cycle, Sandy -# Bridge spends 8 cycles per instruction, but it can schedule them -# every cycle. This means that code targeting Westmere would perform -# suboptimally on Sandy Bridge. Therefore this update. -# -# In addition, non-parallelizable CBC encrypt (as well as CCM) is -# optimized. Relative improvement might appear modest, 8% on Westmere, -# but in absolute terms it's 3.77 cycles per byte encrypted with -# 128-bit key on Westmere, and 5.07 - on Sandy Bridge. These numbers -# should be compared to asymptotic limits of 3.75 for Westmere and -# 5.00 for Sandy Bridge. Actually, the fact that they get this close -# to asymptotic limits is quite amazing. Indeed, the limit is -# calculated as latency times number of rounds, 10 for 128-bit key, -# and divided by 16, the number of bytes in block, or in other words -# it accounts *solely* for aesenc instructions. But there are extra -# instructions, and numbers so close to the asymptotic limits mean -# that it's as if it takes as little as *one* additional cycle to -# execute all of them. How is it possible? It is possible thanks to -# out-of-order execution logic, which manages to overlap post- -# processing of previous block, things like saving the output, with -# actual encryption of current block, as well as pre-processing of -# current block, things like fetching input and xor-ing it with -# 0-round element of the key schedule, with actual encryption of -# previous block. Keep this in mind... -# -# For parallelizable modes, such as ECB, CBC decrypt, CTR, higher -# performance is achieved by interleaving instructions working on -# independent blocks. In which case asymptotic limit for such modes -# can be obtained by dividing above mentioned numbers by AES -# instructions' interleave factor. Westmere can execute at most 3 -# instructions at a time, meaning that optimal interleave factor is 3, -# and that's where the "magic" number of 1.25 come from. "Optimal -# interleave factor" means that increase of interleave factor does -# not improve performance. The formula has proven to reflect reality -# pretty well on Westmere... Sandy Bridge on the other hand can -# execute up to 8 AES instructions at a time, so how does varying -# interleave factor affect the performance? Here is table for ECB -# (numbers are cycles per byte processed with 128-bit key): -# -# instruction interleave factor 3x 6x 8x -# theoretical asymptotic limit 1.67 0.83 0.625 -# measured performance for 8KB block 1.05 0.86 0.84 -# -# "as if" interleave factor 4.7x 5.8x 6.0x -# -# Further data for other parallelizable modes: -# -# CBC decrypt 1.16 0.93 0.93 -# CTR 1.14 0.91 n/a -# -# Well, given 3x column it's probably inappropriate to call the limit -# asymptotic, if it can be surpassed, isn't it? What happens there? -# Rewind to CBC paragraph for the answer. Yes, out-of-order execution -# magic is responsible for this. Processor overlaps not only the -# additional instructions with AES ones, but even AES instuctions -# processing adjacent triplets of independent blocks. In the 6x case -# additional instructions still claim disproportionally small amount -# of additional cycles, but in 8x case number of instructions must be -# a tad too high for out-of-order logic to cope with, and AES unit -# remains underutilized... As you can see 8x interleave is hardly -# justifiable, so there no need to feel bad that 32-bit aesni-x86.pl -# utilizies 6x interleave because of limited register bank capacity. -# -# Higher interleave factors do have negative impact on Westmere -# performance. While for ECB mode it's negligible ~1.5%, other -# parallelizables perform ~5% worse, which is outweighed by ~25% -# improvement on Sandy Bridge. To balance regression on Westmere -# CTR mode was implemented with 6x aesenc interleave factor. - -# April 2011 -# -# Add aesni_xts_[en|de]crypt.
