Revert "Replace aes_nohw with a bitsliced implementation."
This reverts commit b3ac6bb39ad3f980dccae24dfacd97b6e3e57391.
Reason for revert: 32-bit version seems to be broken. I'll debug this
and improve pre-commit CQ coverage before relanding.
Original change's description:
> Replace aes_nohw with a bitsliced implementation.
>
> aes_nohw is currently one of several variable-time table-based
> implementations in C or assembly (armv4, x86, and x86_64). Replace all
> of these with a C bitsliced implementation, with 32-bit, 64-bit, and
> 128-bit (SSE2) variants. This is based on the algorithms described in:
>
> https://bearssl.org/constanttime.html#aes
> https://eprint.iacr.org/2009/129.pdf
> https://eprint.iacr.org/2009/191.pdf
>
> This makes our AES implementation constant-time in all build
> configurations!
>
> There were far too many benchmarks to put in the commit message.
> Instead, please refer to this fancy spreadsheet:
> https://docs.google.com/spreadsheets/d/1wDCzfkPl7brfjWJKq55awQjwCPhOYI8O7zSQZuEc2Xg/edit?usp=sharing
>
> Parallel modes on x86 and x86_64 do fine due to the SSE2 code. AES-GCM
> actually gets faster. The 64-bit (4x) bitsliced implementation is less
> effective at speeding parallel modes but still helps. The 32-bit (2x)
> bitsliced implementation even less.
>
> Non-parallel modes, sadly, take a *dramatic* performance hit. I tried a
> constant-time table lookup for comparison, but bitslicing was still
> better. This implementation performs comparably to the table in
> BearSSL's documentation, which suggests I didn't do anything obviously
> wrong. (Note BearSSL's table for 'ct' corresponds to a 32-bit bitsliced
> implementation compiled for 64-bit. Compiling this implementation for
> 64-bit matches, but compiling it for 32-bit seems to be considerably
> slower.)
>
> Assumptions that may make this palatable:
>
> - AES-GCM is by far the most important AES mode, and we perform okay
> with it. Modern things aren't built out of CBC.
>
> - A nontrivial chunk of Chrome users on Windows don't have SSSE3 and
> would be affected by this change. They would get the SSE2 version
> which performs well for AES-GCM *and* is constant-time.
>
> - ARM devices are primarily mobile which cycles hardware much faster.
> Chrome for Android has required NEON for several years now, so it
> would not run this code. (Aside from https://crbug.com/341598.)
>
> - aarch64 mandates NEON, so it would not run this code.
>
> - QUIC packet number encryption does use a one-off block operation, but
> only once per packet.
>
> - Arguably this is undoing a performance gain that we never earned. That
> said, it was a dramatic performance gain in places.
>
> As an alternative, we could just check in the SSE2 version and drop the
> x86 and x86_64 table-based assembly, but this still leaves the generic
> code with cache-timing side channels.

-// 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.

-// Block representations.
-//
-// This implementation uses three representations for AES blocks. First, the
-// public API represents blocks as uint8_t[16] in the usual way. Second, most
-// 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 ...
-//
-// Note also that bitwise operations and (logical) byte permutations on an
-// |aes_word_t| work equally for the bitsliced and compact words.
-//
-// We use the compact form in the |AES_KEY| representation to save work
-// inflating round keys into |AES_NOHW_BATCH|. The compact form also exists

+# ====================================================================
+#
+# 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!

+# 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.
