Reland bitsliced aes_nohw implementation.
This relands
https://boringssl-review.googlesource.com/c/boringssl/+/39206. See that
CL description for details on the change.
The CL was originally reverted due to a number of ARM-only test
failures. First, there was a test-only issue, resolved in
https://boringssl-review.googlesource.com/c/boringssl/+/39306.
Second, the implementation did not work in unoptimized Android Thumb2
builds. This was caused by a clang bug introduced in
https://reviews.llvm.org/rL340261 and fixed in
https://reviews.llvm.org/rL351310. aes_nohw_(un)compact_block have
been rewritten in an attempt to dodge the bug. Performance of optimized
builds with clang and gcc do not appear to be affected by the rewrite.
See the delta from patch set 1.
(I had hoped to improve precommit CQ coverage before landing this, but
both failures turned out to be ARM-only. Either way, there are now
32-bit and 64-bit SSE2-less configurations so the 32-bit and 64-bit
implementations have CQ coverage.)

+// This file contains a constant-time implementation of AES, bitsliced with
+// 32-bit, 64-bit, or 128-bit words, operating on two-, four-, and eight-block
+// batches, respectively. The 128-bit implementation requires SSE2 intrinsics.
+//
+// This implementation is based on the algorithms described in the following
+// references:
+// - https://bearssl.org/constanttime.html#aes
+// - https://eprint.iacr.org/2009/129.pdf
+// - https://eprint.iacr.org/2009/191.pdf

+
+// Word operations.
+//
+// An aes_word_t is the word used for this AES implementation. Throughout this
+// file, bits and bytes are ordered little-endian, though "left" and "right"
+// shifts match the operations themselves, which makes them reversed in a
+// little-endian, left-to-right reading.
+//
+// Eight |aes_word_t|s contain |AES_NOHW_BATCH_SIZE| blocks. The bits in an
+// |aes_word_t| are divided into 16 consecutive groups of |AES_NOHW_BATCH_SIZE|
+// bits each, each corresponding to a byte in an AES block in column-major
+// order (AES's byte order). We refer to these as "logical bytes". Note, in the
+// 32-bit and 64-bit implementations, they are smaller than a byte. (The
+// contents of a logical byte will be described later.)
+//
+// MSVC does not support C bit operators on |__m128i|, so the wrapper functions
+// |aes_nohw_and|, etc., should be used instead. Note |aes_nohw_shift_left| and
+// |aes_nohw_shift_right| measure the shift in logical bytes. That is, the shift
+// value ranges from 0 to 15 independent of |aes_word_t| and
+// |AES_NOHW_BATCH_SIZE|.
+//
+// This ordering is different from https://eprint.iacr.org/2009/129.pdf, which
+// uses row-major order. Matching the AES order was easier to reason about, and
+// we do not have PSHUFB available to arbitrarily permute bytes.

+// This implementation uses three representations for AES blocks. First, the

+// AES steps are evaluated in bitsliced form, stored in an |AES_NOHW_BATCH|.
+// This stores |AES_NOHW_BATCH_SIZE| blocks in bitsliced order. For 64-bit words
+// containing bitsliced blocks a, b, c, d, this would be as follows (vertical
+// bars divide logical bytes):
+//
+// batch.w[0] = a0 b0 c0 d0 | a8 b8 c8 d8 | a16 b16 c16 d16 ...
+// batch.w[1] = a1 b1 c1 d1 | a9 b9 c9 d9 | a17 b17 c17 d17 ...
+// batch.w[2] = a2 b2 c2 d2 | a10 b10 c10 d10 | a18 b18 c18 d18 ...
+// batch.w[3] = a3 b3 c3 d3 | a11 b11 c11 d11 | a19 b19 c19 d19 ...
+// ...
+//
+// Finally, an individual block may be stored as an intermediate form in an
+// aes_word_t[AES_NOHW_BLOCK_WORDS]. In this form, we permute the bits in each
+// block, so that block[0]'s ith logical byte contains least-significant
+// |AES_NOHW_BATCH_SIZE| bits of byte i, block[1] contains the next group of
+// |AES_NOHW_BATCH_SIZE| bits, and so on. We refer to this transformation as
+// "compacting" the block. Note this is no-op with 128-bit words because then
+// |AES_NOHW_BLOCK_WORDS| is one and |AES_NOHW_BATCH_SIZE| is eight. For 64-bit
+// words, one block would be stored in two words:
+//
+// block[0] = a0 a1 a2 a3 | a8 a9 a10 a11 | a16 a17 a18 a19 ...
+// block[1] = a4 a5 a6 a7 | a12 a13 a14 a15 | a20 a21 a22 a23 ...
+//
+// Observe that the distances between corresponding bits in bitsliced and
+// compact bit orders match. If we line up corresponding words of each block,
+// the bitsliced and compact representations may be converted by tranposing bits
+// in corresponding logical bytes. Continuing the 64-bit example:
+//
+// block_a[0] = a0 a1 a2 a3 | a8 a9 a10 a11 | a16 a17 a18 a19 ...
+// block_b[0] = b0 b1 b2 b3 | b8 b9 b10 b11 | b16 b17 b18 b19 ...
+// block_c[0] = c0 c1 c2 c3 | c8 c9 c10 c11 | c16 c17 c18 c19 ...
+// block_d[0] = d0 d1 d2 d3 | d8 d9 d10 d11 | d16 d17 d18 d19 ...
+//
+// batch.w[0] = a0 b0 c0 d0 | a8 b8 c8 d8 | a16 b16 c16 d16 ...
+// batch.w[1] = a1 b1 c1 d1 | a9 b9 c9 d9 | a17 b17 c17 d17 ...
+// batch.w[2] = a2 b2 c2 d2 | a10 b10 c10 d10 | a18 b18 c18 d18 ...
+// batch.w[3] = a3 b3 c3 d3 | a11 b11 c11 d11 | a19 b19 c19 d19 ...
+//

-# ====================================================================
-#
-# Version 4.3.
-#
-# You might fail to appreciate this module performance from the first
-# try. If compared to "vanilla" linux-ia32-icc target, i.e. considered
-# to be *the* best Intel C compiler without -KPIC, performance appears
-# to be virtually identical... But try to re-configure with shared
-# library support... Aha! Intel compiler "suddenly" lags behind by 30%
-# [on P4, more on others]:-) And if compared to position-independent
-# code generated by GNU C, this code performs *more* than *twice* as
-# fast! Yes, all this buzz about PIC means that unlike other hand-
-# coded implementations, this one was explicitly designed to be safe
-# to use even in shared library context... This also means that this
-# code isn't necessarily absolutely fastest "ever," because in order
-# to achieve position independence an extra register has to be
-# off-loaded to stack, which affects the benchmark result.
-#
-# Special note about instruction choice. Do you recall RC4_INT code
-# performing poorly on P4? It might be the time to figure out why.
-# RC4_INT code implies effective address calculations in base+offset*4
-# form. Trouble is that it seems that offset scaling turned to be
-# critical path... At least eliminating scaling resulted in 2.8x RC4
-# performance improvement [as you might recall]. As AES code is hungry
-# for scaling too, I [try to] avoid the latter by favoring off-by-2
-# shifts and masking the result with 0xFF<<2 instead of "boring" 0xFF.
-#
-# As was shown by Dean Gaudet, the above note turned out to be
-# void. Performance improvement with off-by-2 shifts was observed on
-# intermediate implementation, which was spilling yet another register
-# to stack... Final offset*4 code below runs just a tad faster on P4,
-# but exhibits up to 10% improvement on other cores.
-#
-# Second version is "monolithic" replacement for aes_core.c, which in
-# addition to AES_[de|en]crypt implements AES_set_[de|en]cryption_key.
-# This made it possible to implement little-endian variant of the
-# algorithm without modifying the base C code. Motivating factor for
-# the undertaken effort was that it appeared that in tight IA-32
-# register window little-endian flavor could achieve slightly higher
-# Instruction Level Parallelism, and it indeed resulted in up to 15%
-# better performance on most recent µ-archs...
-#
-# Third version adds AES_cbc_encrypt implementation, which resulted in
-# up to 40% performance improvement of CBC benchmark results. 40% was
-# observed on P4 core, where "overall" improvement coefficient, i.e. if
-# compared to PIC generated by GCC and in CBC mode, was observed to be
-# as large as 4x:-) CBC performance is virtually identical to ECB now
-# and on some platforms even better, e.g. 17.6 "small" cycles/byte on
-# Opteron, because certain function prologues and epilogues are
-# effectively taken out of the loop...
-#
-# Version 3.2 implements compressed tables and prefetch of these tables
-# in CBC[!] mode. Former means that 3/4 of table references are now
-# misaligned, which unfortunately has negative impact on elder IA-32
-# implementations, Pentium suffered 30% penalty, PIII - 10%.
-#
-# Version 3.3 avoids L1 cache aliasing between stack frame and
-# S-boxes, and 3.4 - L1 cache aliasing even between key schedule. The
-# latter is achieved by copying the key schedule to controlled place in
-# stack. This unfortunately has rather strong impact on small block CBC
-# performance, ~2x deterioration on 16-byte block if compared to 3.3.
-#
-# Version 3.5 checks if there is L1 cache aliasing between user-supplied
-# key schedule and S-boxes and abstains from copying the former if
-# there is no. This allows end-user to consciously retain small block
-# performance by aligning key schedule in specific manner.
-#
-# Version 3.6 compresses Td4 to 256 bytes and prefetches it in ECB.
-#
-# Current ECB performance numbers for 128-bit key in CPU cycles per
-# processed byte [measure commonly used by AES benchmarkers] are:
-#
-# small footprint fully unrolled
-# P4 24 22
-# AMD K8 20 19
-# PIII 25 23
-# Pentium 81 78
-#
-# Version 3.7 reimplements outer rounds as "compact." Meaning that
-# first and last rounds reference compact 256 bytes S-box. This means
-# that first round consumes a lot more CPU cycles and that encrypt
-# and decrypt performance becomes asymmetric. Encrypt performance
-# drops by 10-12%, while decrypt - by 20-25%:-( 256 bytes S-box is
-# aggressively pre-fetched.
-#
-# Version 4.0 effectively rolls back to 3.6 and instead implements
-# additional set of functions, _[x86|sse]_AES_[en|de]crypt_compact,
-# which use exclusively 256 byte S-box. These functions are to be
-# called in modes not concealing plain text, such as ECB, or when
-# we're asked to process smaller amount of data [or unconditionally
-# on hyper-threading CPU]. Currently it's called unconditionally from
-# AES_[en|de]crypt, which affects all modes, but CBC. CBC routine
-# still needs to be modified to switch between slower and faster
-# mode when appropriate... But in either case benchmark landscape
-# changes dramatically and below numbers are CPU cycles per processed
-# byte for 128-bit key.
-#
-# ECB encrypt ECB decrypt CBC large chunk
-# P4 52[54] 83[95] 23
-# AMD K8 46[41] 66[70] 18
-# PIII 41[50] 60[77] 24
-# Core 2 31[36] 45[64] 18.5
-# Atom 76[100] 96[138] 60
-# Pentium 115 150 77
-#
-# Version 4.1 switches to compact S-box even in key schedule setup.
-#
-# Version 4.2 prefetches compact S-box in every SSE round or in other
-# words every cache-line is *guaranteed* to be accessed within ~50
-# cycles window. Why just SSE? Because it's needed on hyper-threading
-# CPU! Which is also why it's prefetched with 64 byte stride. Best
-# part is that it has no negative effect on performance:-)
-#
-# Version 4.3 implements switch between compact and non-compact block
-# functions in AES_cbc_encrypt depending on how much data was asked
-# to be processed in one stroke.

-######################################################################
-# Timing attacks are classified in two classes: synchronous when
-# attacker consciously initiates cryptographic operation and collects
-# timing data of various character afterwards, and asynchronous when
-# malicious code is executed on same CPU simultaneously with AES,
-# instruments itself and performs statistical analysis of this data.
-#
-# As far as synchronous attacks go the root to the AES timing
-# vulnerability is twofold. Firstly, of 256 S-box elements at most 160
-# are referred to in single 128-bit block operation. Well, in C
-# implementation with 4 distinct tables it's actually as little as 40
-# references per 256 elements table, but anyway... Secondly, even
-# though S-box elements are clustered into smaller amount of cache-
-# lines, smaller than 160 and even 40, it turned out that for certain
-# plain-text pattern[s] or simply put chosen plain-text and given key
-# few cache-lines remain unaccessed during block operation. Now, if
-# attacker can figure out this access pattern, he can deduct the key
-# [or at least part of it]. The natural way to mitigate this kind of
-# attacks is to minimize the amount of cache-lines in S-box and/or
-# prefetch them to ensure that every one is accessed for more uniform
-# timing. But note that *if* plain-text was concealed in such way that
-# input to block function is distributed *uniformly*, then attack
-# wouldn't apply. Now note that some encryption modes, most notably
-# CBC, do mask the plain-text in this exact way [secure cipher output
-# is distributed uniformly]. Yes, one still might find input that
-# would reveal the information about given key, but if amount of
-# candidate inputs to be tried is larger than amount of possible key
-# combinations then attack becomes infeasible. This is why revised
-# AES_cbc_encrypt "dares" to switch to larger S-box when larger chunk
-# of data is to be processed in one stroke. The current size limit of
-# 512 bytes is chosen to provide same [diminishingly low] probability
-# for cache-line to remain untouched in large chunk operation with
-# large S-box as for single block operation with compact S-box and
-# surely needs more careful consideration...
-#
-# As for asynchronous attacks. There are two flavours: attacker code
-# being interleaved with AES on hyper-threading CPU at *instruction*
-# level, and two processes time sharing single core. As for latter.
-# Two vectors. 1. Given that attacker process has higher priority,
-# yield execution to process performing AES just before timer fires
-# off the scheduler, immediately regain control of CPU and analyze the
-# cache state. For this attack to be efficient attacker would have to
-# effectively slow down the operation by several *orders* of magnitude,
-# by ratio of time slice to duration of handful of AES rounds, which
-# unlikely to remain unnoticed. Not to mention that this also means
-# that he would spend correspondingly more time to collect enough
-# statistical data to mount the attack. It's probably appropriate to
-# say that if adversary reckons that this attack is beneficial and
-# risks to be noticed, you probably have larger problems having him
-# mere opportunity. In other words suggested code design expects you
-# to preclude/mitigate this attack by overall system security design.
-# 2. Attacker manages to make his code interrupt driven. In order for
-# this kind of attack to be feasible, interrupt rate has to be high
-# enough, again comparable to duration of handful of AES rounds. But
-# is there interrupt source of such rate? Hardly, not even 1Gbps NIC
-# generates interrupts at such raging rate...
-#
-# And now back to the former, hyper-threading CPU or more specifically
-# Intel P4. Recall that asynchronous attack implies that malicious
-# code instruments itself. And naturally instrumentation granularity
-# has be noticeably lower than duration of codepath accessing S-box.
-# Given that all cache-lines are accessed during that time that is.
-# Current implementation accesses *all* cache-lines within ~50 cycles
-# window, which is actually *less* than RDTSC latency on Intel P4!

-# instructions are twice as many, they can be scheduled every cycle
-# and not every second one when they are operating on xmm register,
-# so that "arithmetic throughput" remains virtually the same. And

-# AES for ARMv4
-
-# January 2007.
-#
-# Code uses single 1K S-box and is >2 times faster than code generated
-# by gcc-3.4.1. This is thanks to unique feature of ARMv4 ISA, which
-# allows to merge logical or arithmetic operation with shift or rotate
-# in one instruction and emit combined result every cycle. The module
-# is endian-neutral. The performance is ~42 cycles/byte for 128-bit
-# key [on single-issue Xscale PXA250 core].
-
-# May 2007.
-#
-# AES_set_[en|de]crypt_key is added.
-
-# July 2010.
-#
-# Rescheduling for dual-issue pipeline resulted in 12% improvement on
-# Cortex A8 core and ~25 cycles per byte processed with 128-bit key.
-
-# February 2011.
-#
-# Profiler-assisted and platform-specific optimization resulted in 16%
-# improvement on Cortex A8 core and ~21.5 cycles per byte.
