openssl-1.0.0 upgrade
external/openssl Updated version to 1.0.0 openssl.version Updated small records patch for 1.0.0. This is probably the most significant change. patches/small_records.patch Removed bad_version.patch since fix is included in 0.9.8n and beyond patches/README patches/bad_version.patch openssl.config Changed import_openssl.sh to generate armv4 asm with the 1.0.0 scripts, not our backported 0.9.9-dev backported version in patches/arm-asm.patch. import_openssl.sh openssl.config patches/README patches/arm-asm.patch Added -DOPENSSL_NO_STORE to match ./Configure output Added -DOPENSSL_NO_WHIRLPOOL (no-whrlpool) to skip new optional cipher android-config.mk openssl.config Fixed import to remove include directory during import like other imported directories (apps, ssl, crypto) import_openssl.sh Updated UNNEEDED_SOURCES. Pruned Makefiles which we don't use. openssl.config Updated to build newly required files patches/apps_Android.mk patches/crypto_Android.mk Disable some new openssl tools patches/progs.patch Updated upgrade testing notes to include running BigInteger tests README.android Automatically imported android.testssl/ apps/ crypto/ e_os.h e_os2.h include/ ssl/ dalvik Change makeCipherList to skip SSLv2 ciphers that 1.0.0 now returns so there are not duplicate ciphersuite names in getEnabledCipherSuites. libcore/x-net/src/main/native/org_apache_harmony_xnet_provider_jsse_NativeCrypto.cpp Updated OpenSSLSocketImpl_cipherauthenticationmethod for new SSL_CIPHER algorithms -> algorithm_auth (and const-ness) libcore/x-net/src/main/native/org_apache_harmony_xnet_provider_jsse_NativeCrypto.cpp Update to const SSL_CIPHER in OpenSSLSessionImpl_getCipherSuite (and cipherauthenticationmethod) libcore/x-net/src/main/native/org_apache_harmony_xnet_provider_jsse_NativeCrypto.cpp test_EnabledCipherSuites on both SSLSocketTest and SSLServerSocketTest caught the makeCipherList problem. However the asserts where a bit out of sync and didn't give good messages because they didn't actually show what was going on. As part of debugging the issue they found, I tried to make align the asserts and improve their output for the future. libcore/x-net/src/test/java/tests/api/javax/net/ssl/SSLServerSocketTest.java libcore/x-net/src/test/java/tests/api/javax/net/ssl/SSLSocketTest.java vendor/google Add const to X509V3_EXT_METHOD* for 1.0.0 compatibility libraries/libjingle/talk/base/openssladapter.cc Change-Id: I90fb1566dede6034eebc96d2b0dcf4533d9643bf

+# which use exclusively 256 byte S-box. These functions are to be

+######################################################################
+# 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 [diminishigly 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 magnitute,
+# 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 correspondigly more time to collect enough
+# statistical data to mount the attack. It's probably appropriate to
+# say that if adeversary 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!

+# Why not xmm registers? Short answer. It was actually tested and
+# was not any faster, but *contrary*, most notably on Intel CPUs.
+# Longer answer. Main advantage of using mm registers is that movd
+# latency is lower, especially on Intel P4. While arithmetic
+# 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
+# finally the code can be executed even on elder SSE-only CPUs:-)

+# 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.
+
+# May 2007.
+#
+# AES_set_[en|de]crypt_key is added.

+# AES for s390x.
+
+# April 2007.
+#
+# Software performance improvement over gcc-generated code is ~70% and
+# in absolute terms is ~73 cycles per byte processed with 128-bit key.
+# You're likely to exclaim "why so slow?" Keep in mind that z-CPUs are
+# *strictly* in-order execution and issued instruction [in this case
+# load value from memory is critical] has to complete before execution
+# flow proceeds. S-boxes are compressed to 2KB[+256B].
+#
+# As for hardware acceleration support. It's basically a "teaser," as
+# it can and should be improved in several ways. Most notably support
+# for CBC is not utilized, nor multiple blocks are ever processed.
+# Then software key schedule can be postponed till hardware support
+# detection... Performance improvement over assembler is reportedly
+# ~2.5x, but can reach >8x [naturally on larger chunks] if proper
+# support is implemented.
+
+# May 2007.
+#
+# Implement AES_set_[en|de]crypt_key. Key schedule setup is avoided
+# for 128-bit keys, if hardware support is detected.
+
+# Januray 2009.
+#
+# Add support for hardware AES192/256 and reschedule instructions to
+# minimize/avoid Address Generation Interlock hazard and to favour
+# dual-issue z10 pipeline. This gave ~25% improvement on z10 and
+# almost 50% on z9. The gain is smaller on z10, because being dual-
+# issue z10 makes it improssible to eliminate the interlock condition:
+# critial path is not long enough. Yet it spends ~24 cycles per byte
+# processed with 128-bit key.
+#
+# Unlike previous version hardware support detection takes place only
+# at the moment of key schedule setup, which is denoted in key->rounds.
+# This is done, because deferred key setup can't be made MT-safe, not
+# for key lengthes longer than 128 bits.
+#
+# Add AES_cbc_encrypt, which gives incredible performance improvement,
+# it was measured to be ~6.6x. It's less than previously mentioned 8x,
+# because software implementation was optimized.

+# Version 1.1
+#
+# The major reason for undertaken effort was to mitigate the hazard of
+# cache-timing attack. This is [currently and initially!] addressed in
+# two ways. 1. S-boxes are compressed from 5KB to 2KB+256B size each.
+# 2. References to them are scheduled for L2 cache latency, meaning
+# that the tables don't have to reside in L1 cache. Once again, this
+# is an initial draft and one should expect more countermeasures to
+# be implemented...
+#
+# Version 1.1 prefetches T[ed]4 in order to mitigate attack on last
+# round.
+#
+# Even though performance was not the primary goal [on the contrary,
+# extra shifts "induced" by compressed S-box and longer loop epilogue
+# "induced" by scheduling for L2 have negative effect on performance],
+# the code turned out to run in ~23 cycles per processed byte en-/
+# decrypted with 128-bit key. This is pretty good result for code
+# with mentioned qualities and UltraSPARC core. Compared to Sun C
+# generated code my encrypt procedure runs just few percents faster,
+# while decrypt one - whole 50% faster [yes, Sun C failed to generate
+# optimal decrypt procedure]. Compared to GNU C generated code both
+# procedures are more than 60% faster:-)
