5d38f78e29 Rename obj_mac.h to nid.h and make it a multiply-includable header.
obj_mac.h is missing #include guards, so one cannot use NIDs without
pulling in the OBJ_* functions which depend on the giant OID table. Give
it #include guards, tidy up the style slightly, and also rename it to
nid.h which is a much more reasonable name.

obj_mac.h is kept as a forwarding header as, despite it being a little
screwy, some code #includes it anyway.

9e5eb63d01 Document that CRYPTO_library_init may be called concurrently.
This was fixed in 93a5b44296, but it wasn't
documented. Now that there are no pre-init functions to call like
CRYPTO_set_neon_capable, one instance of BoringSSL may be safely shared between
multiple consumers. As part of that, multiple consumers need to be able to call
CRYPTO_library_init possibly redundantlyand possibly on different threads
without synchronization.

(Though there is still that static initializer nuisance. It would be nice to
replace this with internal CRYPTO_once_t's and then CRYPTO_library_init need
only be called to prime armcap for a sandbox. But one thing at a time.)

4b7b048417 Spell __attribute__((format(printf, ...))) with more underscores.
They may be spelled with or without underscores. Alas, a lot of C code (adb,
cURL) seems to find it a popular pasttime to #define printf *before* including
external headers. This is completely nonsense and invalid, but working around
it is easy and is what we (and OpenSSL) were doing before
061332f216.

I'll be sending a patch to cURL tomorrow to make them at least do their macro
trickery after external #includes for sanity. adb's sysdeps.h is a lot longer
and consistently #included first so I'll probably leave that be for lack of
time.

f08c1c6895 Drop support for custom |mod_exp| hooks in |RSA_METHOD|.
The documentation in |RSA_METHOD| says that the |ctx| parameter to
|mod_exp| can be NULL, however the default implementation doesn't
handle that case. That wouldn't matter since internally it is always
called with a non-NULL |ctx| and it is static, but an external
application could get a pointer to |mod_exp| by extracting it from
the default |RSA_METHOD|. That's unlikely, but making that impossible
reduces the chances that future refactorings will cause unexpected
trouble.

fatal_alert isn't read at all right now, and warn_alert is only checked
for close_notify. We only need three states:

 - Not shutdown.
 - Got a fatal alert (don't care which).
 - Got a warning close_notify.

Leave ssl->shutdown alone for now as it's tied up with SSL_set_shutdown
and friends. To distinguish the remaining two, we only need a boolean.

054e151b16 Rewrite ARM feature detection.
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.

Simplify the code by always caching Montgomery contexts in the RSA
structure, regardless of the |RSA_FLAG_CACHE_PUBLIC| and
|RSA_FLAG_CACHE_PRIVATE| flags. Deprecate those flags.

Now that we do this no more than once per key per RSA exponent, the
private key exponents better because the initialization of the
Montgomery contexts isn't perfectly side-channel protected.

6f7374b0ed Restore EC_GROUP_new_by_curve_name and EC_GROUP_set_generator.
Having a different API for this case than upstream is more trouble than is
worth it. This is sad since the new API avoids incomplete EC_GROUPs at least,
but I don't believe supporting this pair of functions will be significantly
more complex than supporting EC_GROUP_new_arbitrary even when we have static
EC_GROUPs.

For now, keep both sets of APIs around, but we'll be able to remove the scar
tissue once Conscrypt's complex dependencies are resolved.

Make the restored EC_GROUP_set_generator somewhat simpler than before by
removing the ability to call it multiple times and with some parameters set to
NULL. Keep the test.

a2f2bc3a40 Align with upstream's error strings, take two.
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.)

true and probably will continue to be true for the foreseeable future[*], but
it'd be nice to do this right.)

fb2c6f8c85 ASN1_get_object should not accept large universal tags.
The high bits of the type get used for the V_ASN1_NEG bit, so when used with
ASN1_ANY/ASN1_TYPE, universal tags become ambiguous. This allows one to create
a negative zero, which should be impossible. Impose an upper bound on universal
tags accepted by crypto/asn1 and add a test.

f4e447c16d Move ASN1_bn_print to a static function in evp/print.c.
It's not used anywhere else, in the library or consumers (Google ones or
ones I could find on Debian codesearch). This is a sufficiently
specialized function that the risk of a third-party library newly
depending on it is low. This removes the last include of asn1.h or
x509.h in crypto/evp.

(This is almost entirely cosmetic because it wasn't keeping the static linker
from doing the right thing anyway. But if we were want to separate the legacy
ASN.1 stack into its own decrepit-like target, we'll need to be pickier about
separation.)

921d906bb6 Reimplement d2i_PrivateKey.
Functions which lose object reuse and need auditing:
- d2i_PrivateKey

This removes evp_asn1.c's dependency on the old stack. (Aside from
obj/.) It also takes old_priv_decode out of EVP_ASN1_METHOD in favor of
calling out to the new-style function. EVP_ASN1_METHOD no longer has any
old-style type-specific serialization hooks, only the PKCS#8 and SPKI
ones.

8ebc0f55a0 Decouple the EVP and PEM code.
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.

17727c6843 Move all signature algorithm code to crypto/x509.
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.

6f0c4db90e Enable upstream's Poly1305 code.
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.
https://rt.openssl.org/Ticket/Display.html?id=4346

Otherwise it seems to work and buys us a decent performance improvement.
Notably, my Nexus 6P is finally faster at ChaCha20-Poly1305 than my Nexus 4!

b9824e2417 Handle SSL_shutdown while in init more appropriately
Calling SSL_shutdown while in init previously gave a "1" response,
meaning everything was successfully closed down (even though it
wasn't). Better is to send our close_notify, but fail when trying to
receive one.

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
because we're not acting on CCS messages!
