OpenSSL's bbio logic is kind of crazy. It would be good to eventually do the
buffering in a better way (notably, bbio is fragile, if not outright broken,
for DTLS). In the meantime, this fixes a number of bugs where the existence of
bbio was leaked in the public API and broke things.
- SSL_get_wbio returned the bbio during the handshake. It must always return
the BIO the consumer configured. In doing so, internal accesses of
SSL_get_wbio should be switched to ssl->wbio since those want to see bbio.
For consistency, do the same with rbio.
- The logic in SSL_set_rfd, etc. (which I doubt is quite right since
SSL_set_bio's lifetime is unclear) would get confused once wbio got wrapped.
Those want to compare to SSL_get_wbio.
- If SSL_set_bio was called mid-handshake, bbio would get disconnected and lose
state. It forgets to reattach the bbio afterwards. Unfortunately, Conscrypt
does this a lot. It just never ended up calling it at a point where the bbio
would cause problems.
- Make more explicit the invariant that any bbio's which exist are always
attached. Simplify a few things as part of that.

Previously, the verification was only done when using the CRT method,
as the CRT method has been shown to be extremely sensitive to fault
attacks. However, there's no reason to avoid doing the verification
when the non-CRT method is used (performance-sensitive applications
should always be using the CRT-capable keys).
Previously, when we detected a fault (attack) through this verification,
libcrypto would fall back to the non-CRT method and assume that the
non-CRT method would give a correct result, despite having just
detecting corruption that is likely from an attack. Instead, just give
up, like NSS does.
Previously, the code tried to handle the case where the input was not
reduced mod rsa->n. This is (was) not possible, so avoid trying to
handle that. This simplifies the equality check and lets us use

Require the public exponent to be available unless
|RSA_FLAG_NO_BLINDING| is set on the key. Also, document this.
If the public exponent |e| is not available, then we could compute it
from |p|, |q|, and |d|. However, there's no reasonable situation in
which we'd have |p| or |q| but not |e|; either we have all the CRT
parameters, or we have (e, d, n), or we have only (d, n). The
calculation to compute |e| exposes the private key to risk of side
channel attacks.
Also, it was particularly wasteful to compute |e| for each
|BN_BLINDING| created, instead of just once before the first
|BN_BLINDING| was created.
|BN_BLINDING| now no longer needs to contain a duplicate copy of |e|,
so it is now more space-efficient.
Note that the condition |b->e != NULL| in |bn_blinding_update| was
always true since commit cbf56a5683.

This removes the thread-unsafe SIGILL-based detection and the
multi-consumer-hostile CRYPTO_set_NEON_capable API. (Changing
OPENSSL_armcap_P after initialization is likely to cause problems.)
The right way to detect ARM features on Linux is getauxval. On aarch64,
we should be able to rely on this, so use it straight. Split this out
into its own file. The #ifdefs in the old cpu-arm.c meant it shared all
but no code with its arm counterpart anyway.
Unfortunately, various versions of Android have different missing APIs, so, on
arm, we need a series of workarounds. Previously, we used a SIGILL fallback
based on OpenSSL's logic, but this is inherently not thread-safe. (SIGILL also
does not tell us if the OS knows how to save and restore NEON state.) Instead,
base the behavior on Android NDK's cpu-features library, what Chromium
currently uses with CRYPTO_set_NEON_capable:
- Android before API level 20 does not provide getauxval. Where missing,
we can read from /proc/self/auxv.
- On some versions of Android, /proc/self/auxv is also not readable, so
use /proc/cpuinfo's Features line.
- Linux only advertises optional features in /proc/cpuinfo. ARMv8 makes NEON
mandatory, so /proc/cpuinfo can't be used without additional effort.
Finally, we must blacklist a particular chip because the NEON unit is broken
(https://crbug.com/341598).
Unfortunately, this means CRYPTO_library_init now depends on /proc being
available, which will require some care with Chromium's sandbox. The
simplest solution is to just call CRYPTO_library_init before entering
the sandbox.
It's worth noting that Chromium's current EnsureOpenSSLInit function already
depends on /proc/cpuinfo to detect the broken CPU, by way of base::CPU.
android_getCpuFeatures also interally depends on it. We were already relying on
both of those being stateful and primed prior to entering the sandbox.

I messed up a few of these.
ASN1_R_UNSUPPORTED_ALGORITHM doesn't exist. X509_R_UNSUPPORTED_ALGORITHM does
exist as part of X509_PUBKEY_set, but the SPKI parser doesn't emit this. (I
don't mind the legacy code having really weird errors, but since EVP is now
limited to things we like, let's try to keep that clean.) To avoid churn in
Conscrypt, we'll keep defining X509_R_UNSUPPORTED_ALGORITHM, but not actually
do anything with it anymore. Conscrypt was already aware of
EVP_R_UNSUPPORTED_ALGORITHM, so this should be fine. (I don't expect
EVP_R_UNSUPPORTED_ALGORITHM to go away. The SPKI parsers we like live in EVP
now.)
A few other ASN1_R_* values didn't quite match upstream, so make those match
again. Finally, I got some of the rsa_pss.c values wrong. Each of those
corresponds to an (overly specific) RSA_R_* value in upstream. However, those
were gone in BoringSSL since even the initial commit. We placed the RSA <-> EVP
glue in crypto/evp (so crypto/rsa wouldn't depend on crypto/evp) while upstream
placed them in crypto/rsa.
Since no one seemed to notice the loss of RSA_R_INVALID_SALT_LENGTH, let's undo
all the cross-module errors inserted in crypto/rsa. Instead, since that kind of
specificity is not useful, funnel it all into X509_R_INVALID_PSS_PARAMETERS
(formerly EVP_R_INVALID_PSS_PARAMETERS, formerly RSA_R_INVALID_PSS_PARAMETERS).
Reset the error codes for all affected modules.
(That our error code story means error codes are not stable across this kind of
refactoring is kind of a problem. Hopefully this will be the last of it.)

EVP_PKEY_asn1_find can already be private. EVP_PKEY_asn1_find_str is used
only so the PEM code can get at legacy encoders. Since this is all
legacy non-PKCS8 stuff, we can just explicitly list out the three cases
in the two places that need it. If this changes, we can later add a
table in crypto/pem mapping string to EVP_PKEY type.
With this, EVP_PKEY_ASN1_METHOD is no longer exposed in the public API
and nothing outside of EVP_PKEY reaches into it. Unexport all of that.

All the signature algorithm logic depends on X509_ALGOR. This also
removes the X509_ALGOR-based EVP functions which are no longer used
externally. I think those APIs were a mistake on my part. The use in
Chromium was unnecessary (and has since been removed anyway). The new
X.509 stack will want to process the signatureAlgorithm itself to be
able to enforce policies on it.
This also moves the RSA_PSS_PARAMS bits to crypto/x509 from crypto/rsa.
That struct is also tied to crypto/x509. Any new RSA-PSS code would
have to use something else anyway.

The C implementation is still our existing C implementation, but slightly
tweaked to fit with upstream's init/block/emits convention.
I've tested this by looking at code coverage in kcachegrind and
valgrind --tool=callgrind --dump-instr=yes --collect-jumps=yes
(NB: valgrind 3.11.0 is needed for AVX2. And even that only does 64-bit AVX2,
so we can't get coverage for the 32-bit code yet. But I had to disable that
anyway.)
This was paired with a hacked up version of poly1305_test that would repeat
tests with different ia32cap and armcap values. This isn't checked in, but we
badly need a story for testing all the different variants.
I'm not happy with upstream's code in either the C/asm boundary or how it
dispatches between different versions, but just debugging the code has been a
significant time investment. I'd hoped to extract the SIMD parts and do the
rest in C, but I think we need to focus on testing first (and use that to
guide what modifications would help). For now, this version seems to work at
least.
The x86 (not x86_64) AVX2 code needs to be disabled because it's broken. It
also seems pretty unnecessary.

The problem with doing a shutdown while in the middle of a handshake
is that once our close_notify is sent we shouldn't really do anything
else (including process handshake/CCS messages) until we've received a
close_notify back from the peer. However the peer might send a CCS
before acting on our close_notify - so we won't be able to read it

Many consumers need SPKI support (X.509, TLS, QUIC, WebCrypto), each
with different ways to set signature parameters. SPKIs themselves can
get complex with id-RSASSA-PSS keys which come with various constraints
in the key parameters. This suggests we want a common in-library
representation of an SPKI.
This adds two new functions EVP_parse_public_key and
EVP_marshal_public_key which converts EVP_PKEY to and from SPKI and
implements X509_PUBKEY functions with them. EVP_PKEY seems to have been
intended to be able to express the supported SPKI types with
full-fidelity, so these APIs will continue this.
This means future support for id-RSASSA-PSS would *not* repurpose
EVP_PKEY_RSA. I'm worried about code assuming EVP_PKEY_RSA implies
acting on the RSA* is legal. Instead, it'd add an EVP_PKEY_RSA_PSS and
the data pointer would be some (exposed, so the caller may still check
key size, etc.) RSA_PSS_KEY struct. Internally, the EVP_PKEY_CTX
implementation would enforce the key constraints. If RSA_PSS_KEY would
later need its own API, that code would move there, but that seems
unlikely.
Ideally we'd have a 1:1 correspondence with key OID, although we may
have to fudge things if mistakes happen in standardization. (Whether or
not X.509 reuses id-ecPublicKey for Ed25519, we'll give it a separate
EVP_PKEY type.)
DSA parsing hooks are still implemented, missing parameters and all for
now. This isn't any worse than before.
Decoupling from the giant crypto/obj OID table will be a later task.

In an SPKI, a DSA key is only an INTEGER, with the group information in
the AlgorithmIdentifier. But a standalone DSAPublicKey is more complex
(and apparently made up by OpenSSL). OpenSSL implemented this with a
write_params boolean and making DSAPublicKey a CHOICE.
Instead, have p_dsa_asn1.c encode an INTEGER directly. d2i_DSAPublicKey
only parses the standalone form. (That code will be replaced later, but
first do this in preparation for rewriting the DSA ASN.1 code.)

Functions which lose object reuse and need auditing:

This adds a handful of bytestring-based APIs to handle EC key
serialization. Deprecate all the old serialization APIs. Notes:
- An EC_KEY has additional state that controls its encoding, enc_flags
and conv_form. conv_form is left alone, but enc_flags in the new API
is an explicit parameter.
- d2i_ECPrivateKey interpreted its T** argument unlike nearly every
other d2i function. This is an explicit EC_GROUP parameter in the new
function.
- The new specified curve code is much stricter and should parse enough
to uniquely identify the curve.
- I've not bothered with a new version of i2d_ECParameters. It just
writes an OID. This may change later when decoupling from the giant
OID table.
- Likewise, I've not bothered with new APIs for the public key since the
EC_POINT APIs should suffice.
- Previously, d2i_ECPrivateKey would not call EC_KEY_check_key and it
was possible for the imported public and private key to mismatch. It
now calls it.

CBS_asn1_ber_to_der currently uses heuristics because implicitly-tagged
constructed strings in BER are ambiguous with implicitly-tagged sequences. It's
not possible to convert BER to DER without knowing the schema.
Fortunately, implicitly tagged strings don't appear often so instead split the
job up: CBS_asn1_ber_to_der fixes indefinite-length elements and constructed
strings it can see. Implicitly-tagged strings it leaves uncoverted, but they
will only nest one level down (because BER kindly allows one to nest
constructed strings arbitrarily!).
CBS_get_asn1_implicit_string then performs the final concatenation at parse
time. This isn't much more complex and lets us parse BER more accurately and
also reject a number of mis-encoded values (e.g. constructed INTEGERs are not a
thing) we'd previously let through. The downside is the post-conversion parsing
code must be aware of this limitation of CBS_asn1_ber_to_der. Fortunately,
there's only one implicitly-tagged string in our PKCS#12 code.
(In the category of things that really really don't matter, but I had spare
cycles and the old BER converter is weird.)

This is CVE-2016-0701 for OpenSSL, reported by Antonio Sanso. It is a no-op for
us as we'd long removed SSL_OP_DH_SINGLE_USE and static DH cipher suites. (We
also do not parse or generate X9.42 DH parameters.)
However, we do still have the APIs which return RFC 5114 groups, so we should
perform the necessary checks in case later consumers reuse keys.
Unlike groups we generate, RFC 5114 groups do not use "safe primes" and have
many small subgroups. In those cases, the subprime q is available. Before using
a public key, ensure its order is q by checking y^q = 1 (mod p). (q is assumed
to be prime and the existing range checks ensure y is not 1.)

OpenSSL accepts both OID 2.5.8.1.1 and OID 1.2.840.113549.1.1.1 for RSA
public keys. The latter comes from RFC 3279 and is widely implemented.
The former comes from the ITU-T version of X.509. Interestingly,
2.5.8.1.1 actually has a parameter, which OpenSSL ignores:
rsa ALGORITHM ::= {
KeySize
IDENTIFIED BY id-ea-rsa
}
KeySize ::= INTEGER
Remove support for 2.5.8.1.1 completely. In tests with a self-signed
certificate and code inspection:
- IE11 on Win8 does not accept the certificate in a TLS handshake at
all. Such a certificate is fatal and unbypassable. However Microsoft's
libraries do seem to parse it, so Chrome on Windows allows one to
click through the error. I'm guessing either the X.509 stack accepts
it while the TLS stack doesn't recognize it as RSA or the X.509 stack
is able to lightly parse it but not actually understand the key. (The
system certificate UI didn't display it as an RSA key, so probably the
latter?)
- Apple's certificate library on 10.11.2 does not parse the certificate
at all. Both Safari and Chrome on Mac treat it as a fatal and
unbypassable error.
- mozilla::pkix, from code inspection, does not accept such
certificates. However, Firefox does allow clicking through the error.
This is likely a consequence of mozilla::pkix and NSS having different
ASN.1 stacks. I did not test this, but I expect this means Chrome on
Linux also accepts it.
Given IE and Safari's results, it should be safe to simply remove this.
Firefox's data point is weak (perhaps someone is relying on being able
to click-through a self-signed 2.5.8.1.1 certificate), but it does
further ensure no valid certificate could be doing this.
The following is the 2.5.8.1.1 certificate I constructed to test with.
The private key is key.pem from ssl/test/runner:

It takes ownership of the buffer, so it's not actually const. The
const-ness gets dropped once it transits through EVP_PKEY_CTX_ctrl.
Also compare against INT_MAX explicitly for the overflow check. I'm not sure
whether the casting version is undefined, but comparing against INT_MAX matches
the rest of the codebase when transiting in and out of signed ints.

It's never used. It's not clear why one would want such a thing.
EVP_PKEY_CTX has no way for callers to register callbacks, which means
there shouldn't be a way for the library to present you an EVP_PKEY_CTX
out-of-context. (Whereas app_data/ex_data makes sense on SSL because of
its numerous callbacks or RSA because of RSA_METHOD.)

There's many ways to serialize a BIGNUM, so not including asn1 in the name is
confusing (and collides with BN_bn2cbb_padded). Since BN_asn12bn looks
ridiculous, match the parse/marshal naming scheme of other modules instead.

OpenSSL 1.1.0 doesn't seem to have these two, so this isn't based on anything.
Have them return uint64_t in preparation for switching the internal
representation to uint64_t so ssl_record_sequence_update can go away.

node.js is, effectively, another bindings library. However, it's better
written than most and, with these changes, only a couple of tiny fixes
are needed in node.js. Some of these changes are a little depressing
however so we'll need to push node.js to use APIs where possible.
Changes:
∙ Support verify_recover. This is very obscure and the motivation
appears to be https://github.com/nodejs/node/issues/477 – where it's
not clear that anyone understands what it means :(
∙ Add a few, no-op #defines
∙ Add some members to |SSL_CTX| and |SSL| – node.js needs to not
reach into these structs in the future.
∙ Add EC_get_builtin_curves.
∙ Add EVP_[CIPHER|MD]_do_all_sorted – these functions are limited to
decrepit.
