fac6fb99da Opaquify CONF.
This removes the last mention of LHASH in public headers. This can only
break people who stack-allocate CONF or access the data field. The
latter does not happen (external code never calls lh_CONF_VALUE_*
functions). The former could not work as there would be no way to clean
it up.

Update-Note: CONF is now opaque.

e17e14dfe1 Remove LHASH_OF mention in X509V3_EXT_conf_nid.
Everyone calls this with NULL anyway. People never actually use
lh_CONF_VALUE_* functions (or any other lh_* functions for that matter).

Also remove unused X509V3_EXT_CRL_add_conf prototype.

This removes one of the last mentions of LHASH_OF in public headers.

Update-Note: X509V3_EXT_conf_nid calls that pass a non-NULL first
    parameter will fail to compile.

a943613e40 Inline functions are apparently really complicated.
C and C++ handle inline functions differently. In C++, an inline function is
defined in just the header file, potentially emitted in multiple compilation
units (in cases the compiler did not inline), but each copy must be identical
to satsify ODR. In C, a non-static inline must be manually emitted in exactly
one compilation unit with a separate extern inline declaration.

In both languages, exported inline functions referencing file-local symbols are
problematic. C forbids this altogether (though GCC and Clang seem not to
enforce it). It works in C++, but ODR requires the definitions be identical,
including all names in the definitions resolving to the "same entity". In
practice, this is unlikely to be a problem, but an inline function that returns
a pointer to a file-local symbol could compile oddly.

Historically, we used static inline in headers. However, to satisfy ODR, use
plain inline in C++, to allow inline consumer functions to call our header
functions. Plain inline would also work better with C99 inline, but that is not
used much in practice, extern inline is tedious, and there are conflicts with
the old gnu89 model: https://stackoverflow.com/questions/216510/extern-inline

For dual C/C++ code, use a macro to dispatch between these. For C++-only
code, stop using static inline and just use plain inline.

Update-Note: If you see weird C++ compile or link failures in header
    functions, this change is probably to blame. Though this change
    doesn't affect C and non-static inline is extremely common in C++,
    so I would expect this to be fine.

7c3ce519e8 Actually disable RandTest.Fork on iOS.
TARGET_OS_IPHONE isn't defined without including <TargetConditionals.h>. Oops.
Confirmed now that OPENSSL_IOS gets defined where we expect.

Update-Note: There is some chance this will fail to build on some macOS host
builds of Android? https://codereview.chromium.org/538563002 suggests something
weird happens. However those Android builds of BoringSSL would already be
problematic because they'd set OPENSSL_STATIC_ARMCAP thinking they were iOS.
Thus I've intentionally kept the assumption that __APPLE__ implies a Darwin
target. If it goes through, all is well. If not, we'll learn more about that
configuration and that we likely need to revise our OPENSSL_APPLE definition.

73535ab252 Fix undefined block128_f, etc., casts.
This one is a little thorny. All the various block cipher modes
functions and callbacks take a void *key. This allows them to be used
with multiple kinds of block ciphers.

However, the implementations of those callbacks are the normal typed
functions, like AES_encrypt. Those take AES_KEY *key. While, at the ABI
level, this is perfectly fine, C considers this undefined behavior.

If we wish to preserve this genericness, we could either instantiate
multiple versions of these mode functions or create wrappers of
AES_encrypt, etc., that take void *key.

The former means more code and is tedious without C++ templates (maybe
someday...). The latter would not be difficult for a compiler to
optimize out. C mistakenly allowed comparing function pointers for
equality, which means a compiler cannot replace pointers to wrapper
functions with the real thing. (That said, the performance-sensitive
bits already act in chunks, e.g. ctr128_f, so the function call overhead
shouldn't matter.)

But our only 128-bit block cipher is AES anyway, so I just switched
things to use AES_KEY throughout. AES is doing fine, and hopefully we
would have the sense not to pair a hypothetical future block cipher with
so many modes!

217bfd3c96 Fix undefined function pointer casts in IMPLEMENT_PEM_*.
While it is okay to cast function pointers into different types for
generic storage, the pointer must be cast back to the exact same type
when calling. In particular, although C libraries do this sort of thing
all the time, calling a T* d2i function as a void* d2i function is
undefined:

  If the function is defined with a type that is not compatible with the
  type (of the expression) pointed to by the expression that denotes the
  called function, the behavior is undefined

Fix some instances in the PEM/ASN1 wrapper functions. Synthesize helper
functions instead.

This CL just addresses the function pointer issues. The inherited legacy
OpenSSL ASN.1 code is still full other questionable data pointer dances
that will be much more difficult to excise. Continuing to exise that
code altogether (it is already unshipped from Cronet and unshipped from
Chrome but for WebRTC) is probably a better tack there.

This removes one (of many many) places where we require
-fsanitize-cfi-icall-generalize-pointers.

5b33effa72 Rename OPENSSL_NO_THREADS, part 1.
BoringSSL depends on the platform's locking APIs to make internal global
state thread-safe, including the PRNG. On some single-threaded embedded
platforms, locking APIs may not exist, so this dependency may be disabled
with a build flag.

Doing so means the consumer promises the library will never be used in any
multi-threaded address space. It causes BoringSSL to be globally thread-unsafe.
Setting it inappropriately will subtly and unpredictably corrupt memory and
leak secret keys.

Unfortunately, folks sometimes misinterpreted OPENSSL_NO_THREADS as skipping an
internal thread pool or disabling an optionally extra-thread-safe mode. This is
not and has never been the case. Rename it to
OPENSSL_NO_THREADS_CORRUPT_MEMORY_AND_LEAK_SECRETS_IF_THREADED to clarify what
this option does.

Update-Note: As a first step, this CL makes both OPENSSL_NO_THREADS and
OPENSSL_NO_THREADS_CORRUPT_MEMORY_AND_LEAK_SECRETS_IF_THREADED work. A later CL
will remove the old name, so migrate callers after or at the same time as
picking up this CL.

b5e4a225e4 Use sdallocx, if available, when deallocating.
Providing a size hint to the allocator is substantially faster,
especially as we already know/need the size for OPENSSL_cleanse.

We provide a weak symbol that falls back to free when a malloc with
sdallocx is not statically linked with BoringSSL.

Alternatives considered:
* Use dlsym():  This is prone to fail on statically linked binaries
  without symbols.  Additionally, the extra indirection adds call
  overhead above and beyond the linker resolved technique we're using.
* Use CMake rules to identify whether sdallocx is available:  Once the
  library is built, we may link against a variety of malloc
  implementations (not all of which may have sdallocx), so we need to
  have a fallback when the symbol is unavailable.

host of strangeness surrounding wpend_buf. For now, remove the unused hook.

e77c27d734 Automatically disable assembly with MSAN.
MSAN is incompatible with hand-written assembly code. Previously we
required that OPENSSL_NO_ASM be set when building with MSAN, and the
CMake build would take care of this. However, with other build systems
it wasn't always so easy.

This change automatically disables assembly when the compiler is
configured for MSAN.

632d1127df Add some RAND_bytes tests.
We're a far cry from the good old days when we just read from /dev/urandom
without any fuss...

In particular, the threading logic is slightly non-trivial and probably worth
some basic sanity checks. Also write a fork-safety test, and test the
fork-unsafe-buffering path.

The last one is less useful right now, since fork-unsafe-buffering is a no-op
with RDRAND enabled (although we do have an SDE bot...), but it's probably
worth exercising the code in
https://boringssl-review.googlesource.com/c/boringssl/+/31564.

8c7c6356e6 Support symbol prefixes
- In base.h, if BORINGSSL_PREFIX is defined, include
  boringssl_prefix_symbols.h
- In all .S files, if BORINGSSL_PREFIX is defined, include
  boringssl_prefix_symbols_asm.h
- In base.h, BSSL_NAMESPACE_BEGIN and BSSL_NAMESPACE_END are
  defined with appropriate values depending on whether
  BORINGSSL_PREFIX is defined; these macros are used in place
  of 'namespace bssl {' and '}'
- Add util/make_prefix_headers.go, which takes a list of symbols
  and auto-generates the header files mentioned above
- In CMakeLists.txt, if BORINGSSL_PREFIX and BORINGSSL_PREFIX_SYMBOLS
  are defined, run util/make_prefix_headers.go to generate header
  files
- In various CMakeLists.txt files, add "global_target" that all
  targets depend on to give us a place to hook logic that must run
  before all other targets (in particular, the header file generation
  logic)
- Document this in BUILDING.md, including the fact that it is
  the caller's responsibility to provide the symbol list and keep it
  up to date
- Note that this scheme has not been tested on Windows, and likely
  does not work on it; Windows support will need to be added in a
  future commit

492c9aa90c Fill in a fake session ID for TLS 1.3.
Historically, OpenSSL filled in a fake session ID for ticket-only
client sessions. Conscrypt relies on this to implement some weird Java
API where every session has an ID and may be queried out of the client
session cache and, e.g., revoked that way.

(Note that a correct client session cache is not keyed by session ID and
indeed this allows one server to knock out another server's sessions by
matching session IDs. But existing APIs are existing APIs.)

For consistency between TLS 1.2 and TLS 1.3, as well as matching
OpenSSL's TLS 1.3 implementation, do the same in TLS 1.3. Note this
smooths over our cross-version resumption tests by allowing for
something odd: it is now syntactically possible to resume a TLS 1.3
session at TLS 1.2. It doesn't matter either way, but now a different
codepath rejects certain cases.
