The policy engine/key status mechanism needs to be

Previously, OEMCertForbiddenPaddingScheme checks to see if the OEMCrypto
returns a short buffer error on GenerateRSASignature and then resizes it
accordingly if so. If the OEMCrypto does not return this error first
(and instead complains about the padding scheme), the assertion will
return false since the signature has size 1. This CL changes that so it
doesn't matter which error the OEMCrypto returns first.

* Remove Conditional Compilation from OpenSSL/BoringSSL
Author: John W. Bruce <juce@google.com>
[ Merge of http://go/wvgerrit/39460 ]
This change removes the usages of conditional compilation to support
both BoringSSL and OpenSSL, as well as to support multiple versions of
the OpenSSL API. All code is now compiled against one of the two
versions of BoringSSL in third_party/.
Note that in some cases, the kit/ and legacy_kit/ versions of BoringSSL
had different APIs, so when removing the OpenSSL version compatibility
conditional compilation, sometimes the older branch was kept and
sometimes the newer branch was kept.

* Build CE & Jenkins CDMs With BoringSSL from third_party/
Author: John W. Bruce <juce@google.com>
[ Merge of http://go/wvgerrit/37120 ]
Up until now, integrators have been responsible for providing a
compatible crypto library for use by the CE CDM. (either OpenSSL or
BoringSSL) After this change, this decision will no longer be in their
hands. The CE CDM build will always use the copy of BoringSSL in
third_party/, which will be statically linked with our library with
hidden visibility. This allows us to better control what crypto library
we use and will prevent continuing problems with trying to support both
OpenSSL and BoringSSL.
Unfortunately, BoringSSL began using C++11 in mid-2017, and we can't
support C++11 right now. Until we can, we need to use a C++11-free
version of BoringSSL for libssl. The CDM itself will continue to use a
recent BoringSSL, as it only needs libcrypto. But the unit tests that
need libssl have to use the legacy version.

* Modified RNG for Level3 to use more entropy
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/39220 ]
Bug: 65165076
Modified seed generation to use an xor of clock_gettime and
client-implemented code to supply random seeds to the RNG. Modified the RNG
as well to use xoroshiro128+ instead of xorshift, since it uses more
than one seed/state (which are 64-bit) and has higher "statistical quality".
The default implementations for the seed generation use /dev/urandom.
* Configure base path for Level3FileSystem
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/39506 ]
This is in response to b/70354006. This change makes the
Android Level3FileSystem use the existing properties method
GetDevicesFilesBasePath for binderization. The same is done for the
Linux implementation.
* Add legacy_kit/ to BoringSSL Directory
Author: John W. Bruce <juce@google.com>
[ Merge of http://go/wvgerrit/38861 ]
This adds a second copy of BoringSSL to the third_party/boringssl/
directory. This second copy is pinned to the last revision of BoringSSL
not to require C++11 and is not updated by the UPDATE_BORINGSSL.sh
script. This second copy will be used to provide libssl to the tests on
devices that do not support C++11.
Once we support C++11 in the CDM again, this weight should be removed
and all targets should use the copy of BoringSSL in the kit/ directory.
Bug: 67907873
* Use Shared Libraries for Unit Tests
Author: John W. Bruce <juce@google.com>
[ Merge of http://go/wvgerrit/38860 ]
Some unit tests were using a statically-linked CDM instead of a
dynamically-linked one. (Or, in one case, trying to link both ways into
the same binary.) For now, we need to only link dynamically, so that the
unit tests and the CDM can use different versions of BoringSSL.
Long-term, we would like to test both kinds of linkage. (See b/69548115
for that.)
Some unit tests were also using a dynamicaly-linked CDM that was named
such that it appeared to be statically-linked. This patch renames some
targets to make the linkage clearer.

* Get System ID From OEM Cert
Author: John W. Bruce <juce@google.com>
[ Merge of http://go/wvgerrit/37940 ]
(This is a merge of http://go/wvgerrit/30220 . However, it has been
significantly modified in the merge due to needing to support both
OpenSSL and BoringSSL.)
Previously, extracting the system ID was only supported on Keybox-based
systems. This patch adds support for extracting the system ID from the
OEM Certificate chain on Provisioning 3.0 devices. This is done by
getting the Widevine intermediate cert from the chain, finding the
Widevine System ID extension in that cert, and extracting the value.
The code that does the extraction is separate from any code that calls
OEMCrypto so that it can be unit-tested in isolation. This patch adds a
crypto_session_unittest test to do this unit-testing.

I put both changes in this CL since I have to generate Level3 libraries

from the Haystack tool on google3. The second change is from here:
https://critique.corp.google.com/#review/176536782, and addresses
b/69387416. Since the cache_flush function wasn't being used, the

libwvdrmcryptoplugin_hidl has a dependency on libwidevinehidl_utils
which was introduced due to an out of order merge from oc-mr1-dev
to master.

* Automatically generate log location information
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/36563 ]
Currently class and method names are manually added to each log message
in the CDM on android and some other platforms. This change prepends
log messages with file name, line number and function name automatically.
The code is platform specific so it can be enabled and the precise
format configured on a per-platform basis.
As an example, here is a log on android before the change,
11-01 02:48:48.658 D/WVCdm (32198): CryptoSession::Open:
Lock: requested_security_level: Default
and after,
11-01 02:48:48.658 D/WVCdm (32198): [crypto_session.cpp(1108):Open]
Lock: requested_security_level: Default
A follow on CL will remove the manually added class/method information.

* Fix BoringSSL Compatibility of oec_session_util.cpp
Author: John W. Bruce <juce@google.com>
[ Merge of http://go/wvgerrit/37121 ]
A previous change inadvertantly used APIs from OpenSSL that do not exist
in BoringSSL in oec_session_util.cpp. As a temporary fix until we can
move all targets to BoringSSL, this patch switches that file to use
conditional compilation to choose the correct API depending on the
library in use. It does not otherwise change the behavior of the file.

* Create local shared_ptr implementation
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/37600 ]
Derived from protobuf version, which came from google3.
Removed locking (not thread-safe) and removed weak pointers (not
needed for usages in CDM).
Locking can easily be added if needed.
* Revert C++11 usage - back to gnu++98
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/37440 ]
These changes roll back C++11-specific constructs:
std::unique_ptr -> std::auto_ptr
container initializers
nullptr -> NULL
std::shared_ptr to local shared_ptr
compiler flags (-std=c++11 -> -sdt=gnu++98)
NOTE: the "local" shared_ptr implementation is temporarily
a direct reference to the shared_ptr implementation in
third_party/protobuf. This has been fixed (implementation
extracted and moved to core/include) in CL 37600.
BUG: 71650075
Test: Not currently passing. Will be addressed in a subsequent
commit in the chain.
