This cuts out another total_num-length array and simplifies things.
Leading zeros at the front of the schedule don't do anything, so it's
easier to just produce a fixed-length one. (I'm also hoping to
ultimately reuse this function in //third_party/fiat/p256.c and get the
best of both worlds for ECDSA verification; tuned field arithmetic
operations, precomputed table, and variable-time multiply.)

The Chromium certificate verifier ends up encoding a SET OF when
canonicalizing X.509 names. Requiring the caller canonicalize a SET OF
is complicated enough that we should probably sort it for folks. (We
really need to get this name canonicalization insanity out of X.509...)
This would remove the extra level of indirection in Chromium
net/cert/internal/verify_name_match.cc CBB usage.
Note this is not quite the same order as SET, but SET is kind of
useless. Since it's encoding heterogeneous values, it is reasonable to
require the caller just encode them in the correct order. In fact, a DER
SET is just SEQUENCE with a post-processing step on the definition to
fix the ordering of the fields. (Unless the SET contains an untagged
CHOICE, in which case the ordering is weird, but SETs are not really
used in the real world, much less SETs with untagged CHOICEs.)

Instead, require that callers configure the group before setting either
half of the keypair. Additionally, reject EC_KEY_set_group calls that
change the group. This will simplify clearing one more BIGNUM timing

The first step of RSA with the CRT optimization is to reduce our input
modulo p and q. We can do this in constant-time[*] with Montgomery
reduction. When p and q are the same size, Montgomery reduction's bounds
hold. We need two rounds of it because the first round gives us an
unwanted R^-1.
This does not appear to have a measurable impact on performance. Also
add a long TODO describing how to make the rest of the function
constant-time[*] which hopefully we'll get to later. RSA blinding should
protect us from it all, but make this constant-time anyway.
Since this and the follow-up work will special-case weird keys, add a
test that we don't break those unintentionally. (Though I am not above
breaking them intentionally someday...)
Thanks to Andres Erbsen for discussions on how to do this bit properly.

These files are taken from upstream and are used on both ARMv7 and ARMv8

by way of the existing .arch lines.
This can be reproduced by building with the new NDK and passing
-DCMAKE_ASM_FLAGS=-march=armv8-a. Some of our downstream code ends up
passing that to the assembly.
Note this change does not attempt to arrange for ARMv8-A/T32 to get

The fiat-crypto-generated code uses the Montgomery form implementation
strategy, for both 32-bit and 64-bit code.
64-bit throughput seems slower, but the difference is smaller than noise between repetitions (-2%?)
32-bit throughput has decreased significantly for ECDH (-40%). I am
attributing this to the change from varibale-time scalar multiplication
to constant-time scalar multiplication. Due to the same bottleneck,
ECDSA verification still uses the old code (otherwise there would have
been a 60% throughput decrease). On the other hand, ECDSA signing
throughput has increased slightly (+10%), perhaps due to the use of a
precomputed table of multiples of the base point.

As for the former, Andres points out that particular EC implementations

None of the asymmetric crypto we inherented from OpenSSL is
constant-time because of BIGNUM. BIGNUM chops leading zeros off the
front of everything, so we end up leaking information about the first
word, in theory. BIGNUM functions additionally tend to take the full
range of inputs and then call into BN_nnmod at various points.
All our secret values should be acted on in constant-time, but k in
ECDSA is a particularly sensitive value. So, ecdsa_sign_setup, in an
attempt to mitigate the BIGNUM leaks, would add a couple copies of the
order.
This does not work at all. k is used to compute two values: k^-1 and kG.
The first operation when computing k^-1 is to call BN_nnmod if k is out
of range. The entry point to our tuned constant-time curve
implementations is to call BN_nnmod if the scalar has too many bits,
which this causes. The result is both corrections are immediately undone
but cause us to do more variable-time work in the meantime.
Replace all these computations around k with the word-based functions
added in the various preceding CLs. In doing so, replace the BN_mod_mul
calls (which internally call BN_nnmod) with Montgomery reduction. We can
avoid taking k^-1 out of Montgomery form, which combines nicely with
Brian Smith's trick in 3426d10119. Along
the way, we avoid some unnecessary mallocs.
BIGNUM still affects the private key itself, as well as the EC_POINTs.
But this should hopefully be much better now. Also it's 10% faster:

As part of excising BIGNUM from EC scalars, we will need a "words"
version of BN_mod_mul_montgomery. That, in turn, requires BN_sqr and
BN_mul for cases where we don't have bn_mul_mont.
BN_sqr and BN_mul have a lot of logic in there, with the most complex
cases being not even remotely constant time. Fortunately, those only
apply to RSA-sized numbers, not EC-sized numbers. (With the exception, I
believe, of 32-bit P-521 which just barely exceeds the cutoff.) Imposing
a limit also makes it easier to stack-allocate temporaries (BN_CTX
serves a similar purpose in BIGNUM).
Extract bn_mul_small and bn_sqr_small and test them as part of
bn_tests.txt. Later changes will build on these.
If we end up reusing these functions for RSA in the future (though that
would require tending to the egregiously non-constant-time code in the
no-asm build), we probably want to extract a version where there is an
explicit tmp parameter as in bn_sqr_normal rather than the stack bits.

Previously, the ed25519 and SPAKE implementations called field element
operations in ways that did not satisfy the preconditions about ranges
of limbs. Furthermore, replacing signed field arithmetic with unsigned field
arithmetic with similar specifications caused tests to fail. This commit
addresses this in three steps:
(1) Split fe into fe and fe_loose, tracking the bounds
(2) Insert carry operations before uses of fe_add/fe_sub/fe_neg whose
input is already within only the loose bounds
(3) Assert that each field element is within the appropriate bounds at
the beginning and end of every field operation.

Due to a copy-paste error, the call to |left_shift_3| is missing after
reducing the password scalar in SPAKE2. This means that three bits of
the password leak in Alice's message. (Two in Bob's message as the point
N happens to have order 4l, not 8l.)
The “correct” fix is to put in the missing call to |left_shift_3|, but
that would be a breaking change. In order to fix this in a unilateral
way, we add points of small order to the masking point to bring it into
prime-order subgroup.

I do not believe this is actually reachable in BoringSSL, even in the

X509_ATTRIBUTE. That field's value is X509_ATTRIBUTE_SET which cannot

setting the selector to -1 and calling the type's callback which is

Currently we only check that the underlying EC_METHODs match, which
avoids the points being in different forms, but not that the points are
on the same curves. (We fixed the APIs early on so off-curve EC_POINTs
cannot be created.)
In particular, this comes up with folks implementating Java's crypto
APIs with ECDH_compute_key. These APIs are both unfortunate and should
not be mimicked, as they allow folks to mismatch the groups on the two
multiple EC_POINTs. Instead, ECDH APIs should take the public value as a
byte string.
Thanks also to Java's poor crypto APIs, we must support custom curves,
which makes this particularly gnarly. This CL makes EC_GROUP_cmp work
with custom curves and adds an additional subtle requirement to
EC_GROUP_set_generator.
Annoyingly, this change is additionally subtle because we now have a
reference cycle to hack around.

I really need to resurrect the CL to make them entirely static
(https://crbug.com/boringssl/20), but, in the meantime, to make
replacing the EC_METHOD pointer in EC_POINT with EC_GROUP not
*completely* insane, make them refcounted.
OpenSSL did not do this because their EC_GROUPs are mutable
(EC_GROUP_set_asn1_flag and EC_GROUP_set_point_conversion_form). Ours
are immutable but for the two-function dance around custom curves (more
of OpenSSL's habit of making their objects too complex), which is good
enough to refcount.

Our assembly does not use the GOT to reference symbols, which means
references to visible symbols will often require a TEXTREL. This is
undesirable, so all assembly-referenced symbols should be hidden. CPU
capabilities are the only such symbols defined in C.
These symbols may be hidden by doing at least one of:
1. Build with -fvisibility=hidden
2. __attribute__((visibility("hidden"))) in C.
3. .extern + .hidden in some assembly file referencing the symbol.
We have lots of consumers and can't always rely on (1) happening. We
were doing (3) by way of d216b71f90 and
16e38b2b8f, but missed 32-bit x86 because
it doesn't cause a linker error.
Those two patches are not in upstream. Upstream instead does (3) by way
of x86cpuid.pl and friends, but we have none of these files.
Standardize on doing (2). This avoids accidentally getting TEXTRELs on
some 32-bit x86 build configurations. This also undoes
d216b71f90 and
16e38b2b8f. They are no now longer needed
and reduce the upstream diff.

a non-empty rrec an entrance. read_app_data calls into read_handshake.
That'll be fixed in a later patch in this series.)

of the functions used there appear to have feature macros documented.
crypto/bio/printf.c - -std=c99 provides (v)snprintf.
crypto/lhash/lhash_test.cc - we no longer call rand_r.
crypto/mem.c - we no longer call strdup and -std=c99 provides (v)snprintf.
Apple messed up their headers and, if _POSIX_C_SOURCE is defined but
_DARWIN_C_SOURCE isn't, pthread.h no longer defines mach_port_t. They
then shipped a version of libc++ headers that is missing this fix, so
the build breaks:

If one uses XCode, they've hacked their pthread.h to provide mach_port_t
if defined(__cplusplus), but the standalone tools appear to be old and
missing this.
We can work around this by also defining _DARWIN_C_SOURCE in C++ files
that need _POSIX_C_SOURCE, but it appears none of these files actually
need it.

Although we are derived from 1.0.2, we mimic 1.1.0 in some ways around
our FOO_up_ref functions and opaque libssl types. This causes some
difficulties when porting third-party code as any OPENSSL_VERSION_NUMBER
checks for 1.1.0 APIs we have will be wrong.
Moreover, adding accessors without changing OPENSSL_VERSION_NUMBER can
break external projects. It is common to implement a compatibility
version of an accessor under #ifdef as a static function. This then
conflicts with our headers if we, unlike OpenSSL 1.0.2, have this
function.
This change switches OPENSSL_VERSION_NUMBER to 1.1.0 and atomically adds
enough accessors for software with 1.1.0 support already. The hope is
this will unblock hiding SSL_CTX and SSL_SESSION, which will be
especially useful with C++-ficiation. The cost is we will hit some
growing pains as more 1.1.0 consumers enter the ecosystem and we
converge on the right set of APIs to import from upstream.
It does not remove any 1.0.2 APIs, so we will not require that all
projects support 1.1.0. The exception is APIs which changed in 1.1.0 but
did not change the function signature. Those are breaking changes.
Specifically:
- SSL_CTX_sess_set_get_cb is now const-correct.
- X509_get0_signature is now const-correct.
For C++ consumers only, this change temporarily includes an overload
hack for SSL_CTX_sess_set_get_cb that keeps the old callback working.
This is a workaround for Node not yet supporting OpenSSL 1.1.0.
The version number is set at (the as yet unreleased) 1.1.0g to denote
that this change includes https://github.com/openssl/openssl/pull/4384.

wrong. It's .test, not *.test for name constraints. (This doesn't matter
for some_names*.pem, but it does to avoid a false negative in

Second, the CN of certs should be a host, not "Leaf". OpenSSL 1.1.0
checks "host-like" CNs against name constraints too and "Leaf" is
host-like.
I've also made the generator deterministic and checked it in, as PEM

This guards against the name constraints check consuming large amounts
of CPU time when certificates in the presented chain contain an
excessive number of names (specifically subject email names or subject
alternative DNS names) and/or name constraints.
Name constraints checking compares the names presented in a certificate
against the name constraints included in a certificate higher up in the
chain using two nested for loops.
Move the name constraints check so that it happens after signature
verification so peers cannot exploit this using a chain with invalid
signatures. Also impose a hard limit on the number of name constraints
check loop iterations to further mitigate the issue.

This is a reland of https://boringssl-review.googlesource.com/18965
which was reverted due to Windows toolchain problems that have since
been fixed.
We have an SDE bot now and can more easily test things. We also enabled
ADX in rsaz-avx2.pl which does not work without x86_64-mont*.pl enabled.
rsa-avx2.pl's ADX code only turns itself off so that the faster ADX code
can be used... but we disable it.
Verified, after reverting the fix, the test vectors we imported combined
with Intel SDE catches CVE-2016-7055, so we do indeed have test
coverage. Also verified on the Windows version of Intel SDE.
Thanks to Alexey Ivanov for pointing out the discrepancy.

This isn't all of our pointer games by far, but for any code which
doesn't run on armv6, memcpy and pointer cast compile to the same code.
For code with does care about armv6 (do we care?), it'll need a bit more
work. armv6 makes memcpy into a function call.
Ironically, the one platform where C needs its alignment rules is the
one platform that makes it hard to honor C's alignment rules.

This tag doesn't actually do anything, except cause UBSan to point out
that malloc doesn't align that tightly. malloc does, however, appear to
align up to 16-bytes, which is the actual alignment requirement of that
code. So just replace 64 with 16.
When we're juggling less things, it'd be nice to see what toolchain
support for the various aligned allocators looks like. Or maybe someday
we can use C++ new which one hopes is smart enough to deal with all
this.

Public and private RSA keys have the same type in OpenSSL, so it's
probably prudent for us to catch this case with an error rather than

This reverts commit 2cd63877b5. We've
since imported a change to upstream which adds some #defines that should
do the same thing on clang. (Though if gas accepts unified assembly too,
that does seem a better approach. Ah well. Diverging on these files is
expensive.)
This is to reduce the diff and make applying some subsequent changes
easier.

This imports upstream's scrypt implementation, though it's been heavily
revised. I lost track of words vs. blocks vs. bigger blocks too many
times in the original code and introduced a typedef for the fixed-width
Salsa20 blocks. The downside is going from bytes to blocks is a bit
trickier, so I took advantage of our little-endian assumption.
This also adds an missing check for N < 2^32. Upstream's code is making
this assumption in Integerify. I'll send that change back upstream. I've
also removed the weird edge case where a NULL out_key parameter means to
validate N/r/p against max_mem and nothing else. That's just in there to
get a different error code out of their PKCS#12 code.
Performance-wise, the cleanup appears to be the same (up to what little
precision I was able to get here), but an optimization to use bitwise
AND rather than modulus makes us measurably faster. Though scrypt isn't
a fast operation to begin with, so hopefully it isn't anyone's
bottleneck.
This CL does not route scrypt up to the PKCS#12 code, though we could
write our own version of that if we need to later.

Rather than adding a new mode to EVP_PKEY_CTX, upstream chose to tie
single-shot signing to EVP_MD_CTX, adding functions which combine
EVP_Digest*Update and EVP_Digest*Final. This adds a weird vestigial
EVP_MD_CTX and makes the signing digest parameter non-uniform, slightly
complicating things. But it means APIs like X509_sign_ctx can work
without modification.
Align with upstream's APIs. This required a bit of fiddling around
evp_test.cc. For consistency and to avoid baking details of parameter
input order, I made it eagerly read all inputs before calling
SetupContext. Otherwise which attributes are present depend a lot on the
shape of the API we use---notably the NO_DEFAULT_DIGEST tests for RSA
switch to failing before consuming an input, which is odd.
(This only matters because we have some tests which expect the operation
to abort the operation early with parameter errors and match against
Error. Those probably should not use FileTest to begin with, but I'll
tease that apart a later time.)
Upstream also named NID_Ed25519 as NID_ED25519, even though the
algorithm is normally stylized as "Ed25519". Switch it to match.

Originally we had some confusion around whether the features could be
toggled individually or not. Per the ARM C Language Extensions doc[1],
__ARM_FEATURE_CRYPTO implies the "crypto extension" which encompasses
all of them. The runtime CPUID equivalent can report the features
individually, but it seems no one separates them in practice, for now.
(If they ever do, probably there'll be a new set of #defines.)

POWER8 has hardware transactional memory, which glibc uses to implement
locks. In some cases, taking a lock begins a transaction, wrapping
arbitrary user code (!) until the lock is released. If the transaction
is aborted, everything rewinds and glibc tries again with some other
implementation.
The kernel will abort the transaction in a variety of cases. Notably, on
a syscall, the transaction aborts and the syscall *does not happen*.
https://www.kernel.org/doc/Documentation/powerpc/transactional_memory.txt
Yet, for some reason, although the relevant change does appear to be in
the kernel, the transaction is being rewound with getrandom happening
anyway. This does not work very well.
Instead, only guard the DRBG access with the lock, not CRYPTO_sysrand.
This lock is only used to protect the DRBG from the destructor that
zeros everything.

Most importantly, this version of delocate works for ppc64le. It should

that it covers all the cases that the previous delocate.go covered.
It's less stringtastic than the old code, however the parser isn't as
nice as I would have liked. I thought that the reason we put up with
AT&T syntax with Intel is so that assembly syntax could be somewhat
consistent across platforms. At least for ppc64le, that does not appear
to be the case.
