Since Widevine device builds now include APEX prebuilts,
shared library dependencies for the prebuilts are in
are in /apex/com.google.android.widevine/lib[64] rather
than /system/lib[64] or /vendor/lib[64]. When tests are
run not all the dependencies are present.
These changes include
* Statically linking missing dependencies
* Adding /apex/com.google.android.widevine/lib[64] to
the shared library path
* Searching for some of the test executables in
/data/nativetest[64]/vendor/

The Widevine Android CDM should not allow itself to be instantiated
without an app package name, as this breaks SPOID protection.
Unfortunately, pathways exist prior to Android Q that allow this to
happen, and we cannot break these devices by changing the behavior now.
As such, we will only refuse to allow instantiation without an app
package name on devices first launched with Q and later.
This change also migrates the WVDrmFactory and its tests away from
explicitly naming friend classes for individual test, in favor of the
now-recommended "test peer" pattern.

These are a set of CLs merged from the wv cdm repo to the android
repo.
* Android build fixes
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/36322 ]
* Address android compilation errors and warnings
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/36300 ]
* Gyp cleanup and OpenSSL v10.1 support.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/36001 ]
OpenSSL 10.1 has a small number of incompatible changes.
A desktop system upgrade exposed some issue in the build scripts.
Specifically, the linux build was using both third_party/protobufs (2.6.1)
and the version installed on the system (3.0 in this case). The linux
cdm.gyp depended on cdm/cdm.gyp which caused that plus some
additional issues.
These changes are necessary to support g++ version:
g++ (Debian 6.3.0-18) 6.3.0 20170516
Also did some cosmetic rework on run_current_tests to make it easier
to figure out what is going on when something fails.
Also tweaked some of the compiler settings for g++ support (revisit
this later).
* Refactored Service Certificate encryption to allow encryption of arbitrary data.

[ Merge of http://go/wvgerrit/36141 ]
* Send cdm test requests to UAT.

[ Merge of http://go/wvgerrit/36221 ]
This change resolves the all of the
CdmDecryptTest/CdmTestWithDecryptParam.DecryptToClearBuffer
tests.
The license servers will return different keys and keyids.
Sending the request to staging returned key ids and keys that were
not matching what was expected in the unit tests.
* Fix for building L3 OEMCrypto with clang and libc++
Author: yucliu <yucliu@google.com>
[ Merge of http://go/wvgerrit/35740 ]
1. Include <time.h> for time(time_t*).
2. Create endian check union on stack. Clang may create const union
somewhere else, which may cause crash.
* Remove error result when a sublicense session does
not exist. This is not considered an error.
Author: Jeff Fore <jfore@google.com>
[ Merge of http://go/wvgerrit/36080 ]
* Set default mock handler for GetSupportedCertificateTypes
for all unit tests and removed the use of StrictMock from
MockCryptoSession.
Author: Jeff Fore <jfore@google.com>
[ Merge of http://go/wvgerrit/35922 ]
The handler for this was only set for one test and resulted
in a number of failures.
* Set default handler for GetHdcpCapabilities. For
now the default action is to call the real
GetHdcpCapabilities of crypto_session.
Author: Jeff Fore <jfore@google.com>
[ Merge of http://go/wvgerrit/36140 ]
I also changed the mock to a NiceMock to silence
responses to unexpected calls to GetHdcpCapabilities.
The default handler can be overridden as needed in
the individual tests.
This resolves the policy engine test failures.

[ Merge of http://go/wvgerrit/32460 ]
Fix broken test:
WvCdmEnginePreProvTestStaging.ServiceCertificateInitialNoneTest
Fix failures found by address sanitizer:
DeviceFilesUsageInfoTest.RetrieveByProviderSessionToken
DeviceFilesUsageInfoTest.UpdateUsageInfo
NOTE: address sanitizer cannot handle EXPECT_CALL macros containing
a call with a Contains matcher as an argument, e.g.:
EXPECT_CALL(file,
Write(Contains(certificate, wrapped_private_key, 0),
Gt(certificate.size() + wrapped_private_key.size())))
The address sanitizer reports a crash, issues a report, and stops. A
temporary fix is to replace the "Contains()" argument with "_".
* Usage license handling corrections

[ Merge of http://go/wvgerrit/28540 ]

* UsageTableEntry::CopyOldUsageEntry memcpy read out of range.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/32220 ]
The function copies the pst from a variable length input vector
into a 256 byte character array. But the length argument was a
fixed value - MAC_KEY_SIZE. Depending on the actual PST length this
can lead to memcpy reading out of bounds or the PST getting truncated.

* Correct RELEASE_ALL_USAGE_INFO_ERRORs
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/28742 ]
RELEASE_ALL_USAGE_INFO_ERROR_4 and 5 were introduced and made use of in
http://go/wvgerrit/24022 (branch: oc-dev). The error code definitions
were merged over in http://go/wvgerrit/24602.
When http://go/wvgerrit/24622 from cdm_partners_3.2 was merged to master
(http://go/wvgerrit/27723) there was conflict in error codes. The error
codes were adjusted to RELEASE_ALL_USAGE_INFO_ERROR_3 and 4
and were made use of.
To avoid renaming the errors between oc-dev and master, new errors
RELEASE_ALL_USAGE_INFO_ERROR_6 and 7 have been added to handle the
scenarios noted in the merge from cdm_partner_3.2. The other
errors have been reverted back to RELEASE_ALL_USAGE_INFO_ERROR_4 and 5.
They will be used when http://go/wvgerrit/24602 is merged.

[ Merge of http://go/wvgerrit/27921 ]
This is a potential fix for b/36656190. Set aside public
key on first call to get the public key, and use it afterwards.
This gets rid of extra calls to OEMCrypto_GetOEMPublicCertificate(),
which has side-effect of staging the OEM private key.

not being trimmed to match the size returned by
OEMCrypto_GetOEMPublicCertificate().

* Modifiable OEMCrypto
Author: Fred Gylys-Colwell <fredgc@google.com>
[ Merge of http://go/wvgerrit/24729 ]
This CL adds a new variant of the OEMCrypto mock code that adjusts its
behavior based on a configuration file. This is intended for
testing.
For example, a tester can set current_hdcp to 2 in the options.txt
file, push it to the device, and verify that a license is granted for
HDCP 2.0. Then the tester can edit the value of current_hdcp to 1 and
push the file to the device. Playback should stop because the license
is no longer valid.
This variant uses a real level 1 liboemcrypto.so to push data to a
secure buffer. That means we can test playback for a license that
requires secure buffers on an Android device with real secure buffers.

While writing fixes for b/36660726, b/34716264, and b/36065223, it
became clear that having the logic that checks whether the device
supports SPOIDs embedded inside WVDrmPlugin was complicating its code
and inhibiting testing of the class. By moving this check into the code
that instantiates WVDrmPlugin, the result of the calculation can be
independently tested while the tests for WVDrmPlugin can put it in
whatever state they need for the sake of unit testing.
As a consequence of this, the check on retrieving the "deviceUniqueId"
byte array property, which was removed when SPOIDs were implemented, can
be reinstated.

The change to enable 64-bit as a possible target for Widevine Android
made all the unit tests build as 64-bit on compatible platforms. Since
none of these devices support 64-bit properly yet, this is a mistake.
This patch restores unit test builds to being 32-bit only for now.

it will also switch the unit tests to 64-bit mode.

(This is a merge of go/wvgerrit/23686)
This patch removes the makefile lines that previously prevented the
Widevine DRM Plugin from being built as 64-bit on Android. 64-bit
builds are now fully supported.
Only one piece of CDM code has had to change. Due to a bug in
libprotobuf before v3.0, int64 values from protobufs are technically a
different type from int64_t values in code on some 64-bit
architectures. Both have the same in-memory representation at runtime
but are seen as distinct types by the compiler. The compiler will
automatically convert in most places, but template instantiation is
not one of them, so a few places that passed a Protobuf int64 directly
into a template had to be modified.
Please note that tweaks to the mediadrmserver (not covered by this
patch) are needed in order for it to run as 64-bit and load 64-bit DRM
Plugins. Please also note that, as we have no 64-bit L1 OEMCrypto on
any devices, using the 64-bit mediadrmserver and Widevine library will
make your device fall back to L3 for the time being.

* Move some libraries that were being built with the NDK but
statically included into platform code off the NDK.
* Rebuild the obfuscated binaries to use the new STL.
* Remove MIPS support temporarily due to an inability to generate
obfuscated binaries for it. (To be fixed in b/19482469.)

This project is still using stlport (without telling the build system
about it), which was causing (broken) stlport headers to override
libc++ headers, leading to a broken copy of std::enable_if, which in
turn caused <atomic> to fail to compile. Since this project has
prebuilts that will need to be updated before this project can
actually move away from stlport, tell the build system that it is
still using stlport for now.
