We use the standard Apache 2.0 file header, described in "APPENDIX: How
to apply the Apache License to your work."
This was primarily automated by running:
git ls-tree -r --name-only HEAD | xargs go run ./util/relicense.go
See go/boringssl-relicensing-triage for the results of triaging the
output of the tool.
As part of this, switch from taking fiat-crypto under MIT license to
Apache 2.0. (It is licensed under MIT OR Apache-2.0 OR BSD-1-Clause.)
The copyright_summary tool can also be used to confirm we didn't
accidentally drop any copyright lines:
# Run before the CL
git grep -l Copyright | xargs go run ./util/copyright_summary.go -out /tmp/old.json
# Run after the CL
git grep -l Copyright | xargs go run ./util/copyright_summary.go -compare /tmp/old.json

Following the guidance in
https://opensource.google/documentation/reference/releasing/authors,
start maintaining an AUTHORS file.
Update all existing Google copyright lines to 'The BoringSSL Authors'
per the document. This CL also changes the styling to match the new
guidance: removed the '(c)' and the comma.
All other existing copyright lines are left unmodified. Going forward,
our preference will be that new contributions to BoringSSL use 'The
BoringSSL Authors', optionally adding to the AUTHORS file if the
contributor desires.
To avoid being presumptuous, this CL does *not* proactively list every
past contributor in the BoringSSL half of the AUTHORS file. Past
contributors are welcome to send us a patch to be added, or request that
we add you. (Listed or not, the commit log continues to be a more
accurate record, and any existing non-Google copyright lines were left
unmodified.)
The OpenSSL half of the AUTHORS file is seeded with the contents of the
current OpenSSL AUTHORS file, as of writing. The current contents in the
latest revision of the 1.1.1 branch
(b372b1f76450acdfed1e2301a39810146e28b02c) and master
(d992e8729ee38b082482dc010e090bb20d1c7bd5) are identical, just formatted
in text vs Markdown.
Note when reviewing: CONTRIBUTING.md and AUTHORS contain non-mechanical
changes.

Now that we don't depend on external CRYPTO_library_init calls or the
static initializer to initialize CPU capabilities, we can drop a ton of
code.
This makes CRYPTO_library_init, and all its wrappers, into no-ops and
drops the (non-FIPS) static initializer. I've added an internal
OPENSSL_init_cpuid function for the places where the library actually
needs to initialize the CPU vector.
Note this slightly changes the default, previously
static-initializer-full build: previously, CRYPTO_library_init was a
no-op and we relied on the static initializer. Now we uniformly use
CRYPTO_once. This should be an atomic read in the steady state and
essentially free. We can restore the static initializer by default if
this ends up being a problem, but having only one mode is more
straightforward. This also avoids problems if an application calls into
BoringSSL during its own static initializer. Static initializers are not
coherently ordered.
Update-Note: The BORINGSSL_NO_STATIC_INITIALIZER build option and
CRYPTO_library_init are now unnecessary. Once updating past this
revision, those options can now be cleaned up from downstream projects.

We no longer need to define CRYPTO_MUTEX in public headers. This
simplifies a pile of things. First, we can now use pthread_rwlock_t
without any fuss, rather than trying to guess the size on glibc.
As a result, CRYPTO_MUTEX and CRYPTO_STATIC_MUTEX can be merged into one
type. We can almost do this to CRYPTO_refcount_t too. BIO is the one
straggler remaining.

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.

The STL already came up with a threading abstraction for us. If this
sticks, that also means we can more easily write tests elsewhere that
use threads. (A test that makes a bunch of TLS connections on a shared
SSL_CTX run under TSan would be nice. Likewise with some of the messy
RSA locking.)
Update-Note: This adds a dependency from crypto_test to C++11 threads.
Hopefully it doesn't cause issues.
