* Correct error logging
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/40000 ]
In tests, we set the cipher list to avoid using insecure
ciphers when connecting to the provisioning/license service.
The result of setting the cipher list was being incorrectly
validated.

* Move mips cache headers to clear_cache_function.h
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/39700 ]
Since the clear_cache function has been moved away from the dynamic
adapter, we need these conditional includes to be migrated as well for
MIPS.
* Comment out Level 3 debug call until merge
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/39761 ]
This call was introduced in go/wvgerrit/34260/. Since the haystack tool
in google3 still needs this merge, this should be commented out so the
tool can still build until the merge has finished.

* Move external interfaces into level3.h + refactor
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/39673 ]
As part of b/70523618, this CL moves interfaces that partners are
responsible for in Level 3 to level3.h so they can be visible as
part of the CDM release process. It also cleans up some of the
names of the files and adds documentation.

* Remove Security Level Path Backward Compatibility Support
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/39505 ]
From the android K release onwards certificates were stored in
security level specific directories. If upgrading from
previous releases persistent information needed to be moved
to those directories.
Since no device is likely to upgrade from J to Pi, comptibility
support can be removed.

* Rename privacy_crypto_openssl To privacy_crypto_boringssl

* 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.

* Change CDM_Backwards_Compatiblity_Tests to dedicated brances

[ Merge of http://go/wvgerrit/39003 ]
The build scripts used by CDM_Backwards_Compatiblity_Tests now pull
old versions of oemcrypto from the dedicated branches oemcrypto-v*,
which [will eventually] contain old oemcrypto versions, that build
with the current build system with a current boringssl version.

* Refactoring to allow encryption of client ID
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/37460 ]
The code has been restructured to allow encryption of client
identification in provisioning requests. This will be enabled
when server side changes have been made (b/69427217).
* Additional information is included in the Client Identification
portion of the provisioning request.
* Client identification will be encrypted with a service
certificate provided by the app/client. Platform changes
to enable passing this to core are needed. If a service certificate
is not provided, a default one associated with the production Keysmith
will be used.
* Switched APIs in CdmEngine to take a service certificate for
provisioning rather than licensing. Service certificates for
licensing are session based and passed as properties from platform
code.

Add Level 3 Oemcrypto Unit Tests To Run All Tests Script
This CL adds the ability to restrict the oemcrypto unit tests to only
use the fall back level 3. This restriction is per-process, and is
only used while running the unit tests. This allows us to automate
running the unit tests on an android device as both level 1 and level
3 without modifying files in /system/lib. To turn on the restriction,
set the environment variable: FORCE_LEVEL3_OEMCRYPTO=yes.
New level 3 library versions are:
level3/arm/libwvlevel3.a Level3 Library Apr 8 2015 13:09:05

Remove Redundant Tests
This CL modifies the UsageTableTests in oemcrypto_test.cpp so that
they are not all parameterized by new_mac_keys_. This parameter is
used when testing signatures. In particular, we do not need to verify
timing twice.
Also, I modified the run_all_unit_tests.sh script so that the
environment variable GTEST_FILTER is passed down to the android
process. This allows us to use the script to run a limited list of
tests while debugging.

Filter Out API Version 10 Tests

This change is part of OEMCrypto API version 9.
This CL adds verification that a key control block which requires a
specific version of HDCP can be loaded. Also, if secure data path is
not set, it verifies that data is still decrypted.
This CL also adds test that verify DecryptCTR fails when the current
HDCP version is below that in the key control block. The expected
error is OEMCrypto_ERROR_INSUFFICIENT_HDCP. This error code is newly
introduced in this CL.
This is one attempt to clarify HDCP, as specified in b/13626021, and
is a slight modification from previous behavior for the mock and the

Because we do not want to accidentally install a test keybox on a

by default.
If you wish to run these tests, you can override this choice, by
running:

There is an ambiguity in the use of the signature length in
OEMCrypto_GenerateRSASignature. If the pointer to the vector is null,
the function should set the length parameter to be the size of the
buffer needed.
This ambiguity has been clarified in the documentation: the
length returned should be the exact length of the buffer. It
will be corrected in a future release of Qualcomm's L1. However,
we are putting this change in both as a stop-gap and as a
belt-and-suspenders fix.
