Partners have asked for a way to release offline licenses without
using a release message. This is typically used by cable partners who
are caching licenses ahead of time and do not care about usage
statistics.
As part of implementing this request, CdmSession::DeleteLicense() was
renamed to reflect that it only deletes the *files* associated with a
license, and a new CdmSession::DeleteLicense() has been written that
also cleans up other related data.

The CL moves several files used by oemcrypto and cdm into a common
subdirectory, so that it may more easily be shared with partners.
The CORE_DISALLOW_COPY_AND_ASSIGN macro was moved to its own header in
the util/include directory.
This CL removes some references to the mock from other code, and puts
some constants and types, such as the definition of the keybox, into a
header in oemcrypto.

* Level3 cleanup for SHA + field provision headers
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/37581 ]
Moved some redundant macro and struct definitions out of hmac.cpp and
sha.cpp into a separate header file to make the build easier and
cleaner. Also cleaned up unnecessary includes and method signatures
in field_provision.h.
* Address CDM_All_Tests failures
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/37580 ]
CDM engine tests for CE CDM occasionally fails when CDM_All_Tests
is run by the build server. The failures are due to a nonce generation
error. If provisioning fails due to a nonce generation error, a delay
followed by a retry will be attempted.
* Update OEMCrypto version to 13 in cdm.gyp
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/37520 ]
* Use per-session service certificates for licensing
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/37260 ]
These changes allow for service certificates to be specified on a
per-session basis rather than use one common to a CdmEngine instance.
This also allows for a service certificate request and response handling
when allowed on the platform, when privacy mode is enabled and a service
certificate is not provided.
Request license tests accept a service certificate command line
parameter in hex (ascii). Earlier it expected it in binary.
Bug: 68328352
* Refactor service certificate parsing
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/37060 ]
Service certificates may still be set in CdmEngine but service
certificate requests and responses have been moved from CdmEngine
to ServiceCertificate. This allows them to be called from lower
in the heirarchy (a class that CdmEngine depends on).

* Revert "C++11: Replace OVERRIDE def with override keyword"
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/37020 ]
This reverts commit 2d3fb5c4c8f4cf5c986ee43723914a23cf76e8f0.
* Modified scripts/makefiles for L3 build
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/37220 ]
Changed build-android-haystack.sh and make_fastball_libwvlevel3.sh
to build using the new liboemcrypto.cpp file. Also changed
makefiles to build using the new file. Renamed liboemcrypto.cc to
liboemcrypto.cpp to make it consistent across android and CE CDM. Added
static libraries that were rebuilt using this change.
* Added android implementations for Level3
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/37181 ]
Moved getUniqueID and added Level3FileSystem implementations for
android. Also deleted redundant and unnecessary methods from
anroid_keybox.cpp.
* Refactored getUniqueID and updated libl3oemcrypto.cc
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/37160 ]
Renamed getUniqueID header and added comments to make it clear what the
function is doing. Also removed obfuscation of the method name since it
is implemented by the partner. Updated the libl3oemcrypto.cc file to
reflect the change as well as be obfuscated.
* Moved clear_cache function out of entry_points
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/37040 ]
clear_cache function is unobfuscated and relies on compiler flags to
work properly, and therefore should be removed from the
libl3oemcrypto.cpp file and linked during the final build.
* Minor gyp changes and added L3 build file
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/36480 ]
Gyp changes to cdm_unittests.gyp to make the test Level3FileSystem build
only on a level3 build and to oec_level3.gyp to be compatible with the
changes to the x86-64 platform settings changes (and to use -Wno-unused
to catch all unused warnings the libl3oemcrypto.cc might cause). This
change also includes an x86-64 libl3oemcrypto.cc so a Level3 OEMCrypto can build.
* Merge CE & Linux file system/factory + dynamic adapter changes
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/36220 ]
This CL merges the changes from
I27f5037e4fcea94abd84181f55053843b68f3e8d - it adds the CE
implementation for the file system, as well as the factory methods
needed to build the file system (and their implementations for both CE
and linux). As part of the merge, since the Linux build relies on the
dynamic adapter, that was fixed and gyp changes were made to reflect the
change.
* Cherry pick change to retrieve/save provisioning cert
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/30000 ]
This is cherry pick from level3-dev-3.3 of a merge of
I4f5dc5c216fa916e0bca0631c4ceda68859baf1d to save the
certificate for future tests with the current test host setup.
* Merged changes of usage/linux impl of L3FileSystem
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/35541 ]
This is a merge of change I15d38b3c36933d061d168e0ec30bcefd0182f32d. It
also adds a similar change in usage of L3FileSystem write for a line in
usage_table.cpp.
* Add cdm build changes for new Level3 build
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/34600 ]
Original CL: Ib611cf8a8589afa5cd25d6dc5b0aa43922cfda1e
Adds level3 oemcrypto library for static adapter. Includes changes to
gyp files to choose between oemcrypto libraries. Also includes changes
to the dynamic adapter, level3 headers, and entry_points to be
compatible with the function signature differences when using the
static adapter.
* Merge OEMCrypto Level3FileSystem interface
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/34541 ]
This merges in the interface for the Level3FileSystem object from
level3_dev_3.3 as well as the linux implementation. Furthermore, this
merge includes changes in properties and gyp files to allow compilation.
The associated changes are I3f1c58f0e3782de0669a96725a38673a26cc1a49,
I9fb2d10b0f966896bea685166c6b6b2e33c995dd, and

* Merged misc. changes to Level3 files
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/33303 ]
Continuation of I03d3aa1a308f2f010dcb6f5e15f927e81e42925b. These changes
are miscellaneous changes from level3-dev-3.3 involving include
statements, Caligo compatibility, and new Level3 signatures from changes
Ibc5befd492b295970e839f3481e2b512b52dcb08 and
If599e62c72b5eb40c53633cd72a4d20dc859ee52.
* Merged change involving getUniqueId()
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/33302 ]
This is a merge from level3-dev-3.3. This change
(Ibc5befd492b295970e839f3481e2b512b52dcb08) involves
separating out the method getUniqueId() from the linux_ and
android_keybox.cpp. This was done so that clients can
supply the necessary implementation for the method.
* Merged needle file changes from level3-dev-3.3
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/33301 ]
Continuation of I3dbf34bab526945720280f819dd3212ae982d2f7. These are
changes (Ibc5befd492b295970e839f3481e2b512b52dcb08) involving the
compiled needles for Haystack. Major changes include function signature
changes, adding non-state needles automatically, and include statements.
* Merged keybox/usage table access and function sigs
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/33300 ]
These are changes from level3-dev-3.3. They involve changing function
signatures/include files for the new Haystack runtime
(Ibc5befd492b295970e839f3481e2b512b52dcb08). They are also
related to change I0285e6d85e80b06b7df1ed298cd1145a6c9c4842. Keybox and
usage table file names are replaced with constant needles. Furthermore,
a state needle was added that removes the OldUsageTable file. In
addition, this CL includes removals of method references that are now
stale due to the introduction of change
I9fb2d10b0f966896bea685166c6b6b2e33c995dd.
* Android unit test build fixes
Author: Srujan Gaddam <srujzs@google.com>
[ Merge of http://go/wvgerrit/37380 ]
Removed crypto_session_unittest from build script (introduced
in http://go/wvgerrit/32824), since crypto_session.cpp requires
some changes to be merged over from oc-mr1-dev (b/64456400).
Added oemcrypto_session_tests_helper.cpp to the oemcrypto test
makefile so the oemcrypto unit tests can link in the
methods from the refactor in http://go/wvgerrit/36562.

* Clean up memory leaks in tests.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/32600 ]
This is the first pass at cleaning up memory leaks. These leaks
were affecting a lot of tests, making it hard to identify more
serious leaks.
Switch to unique_ptr<> pointers for CdmEngine in

* Fix broken tests - linux-only & address sanitizer failures.
Author: Gene Morgan <gmorgan@google.com>
[ 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 "_".

* 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.

* 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.

Service Certificates are used in two places, provisioning and
licensing. The service certificate code depended on a session_id
to get and set the service certificate properties, but the session_id
was not available in the provisioning path.
This patch pulls out the property lookup by session_id dependency,
and passes the CdmImpl's property_set into the provisioning code, so
the service certificate can be read and written there.

* Corrects usage_table_header lifetime management. Earlier the
UsageTableHeader class was a singleton tied to the CdmEngine lifetime.
With SPOIDs there might be multiple concurrent CdmEngine objects.
The UsageTableHeader class is now associated with OEMCrypto
lifetime. There are two UsageTableHeader objects one for each L1 and L3.
These get allocated/deallocated on OEMCrypto Initialization/Termination
respectively.
* UsageTableHeader requires OEMCrypto, file read/writes and
metric gathering to perform its required functionality. Because of the
lifetime changes, CryptoSession, DeviceFiles and MetricsGroup objects
need to passed to the methods rather than at Creation time.
* Miscellaneous fixes, when moving or deleteing entries.
* Adds usage_table_header_unittests.

[ Merge of https://go/wvgerrit/16940 ]
An alternate scenario to renewing keys is to load the same keys in
a separate session and make use of them by using the session sharing
feature.
Session sharing involves iterating through a map of sessions and
returning the first session that contains the Key ID. In certain cases
(license about to expire) we might prefer an alternate session
be chosen.
Licenses may expire in two ways. Policy engine, driven by a 1 second
timer may detect expiry and send an asynchronous event. OEMCrypto may
also detect expiry based on information in the key control block
and return an error during decryption. It is possible that these
may differ by upto a second. This can lead to issues where decryption
fails but EVENT_KEY_EXPIRED is not generated till later.
It is possible to address this by using information from both timers
to notify the app about expiry. To implement this correctly will
add complexity and require synchronization between threads. To avoid
this an alternate solution is, if session sharing is used, to pick
the session that has a license with the longest remaining validity.

This is a merge of squashed CLs.
* Cdm Session and Engine interface clean up
[ Merge of http://go/wvgerrit/16387 ]
Key Set Ids have been removed from the CdmSession interface
(GenerateKeyRequest, Addkey) as they can be queried by an accessor.
The CdmEngine interface now allows one to specify or retrieve a session ID,
since both were not being used in a single call. Key set IDs are no longer
returned though GenerateKeyRequest as they was not being used.
* Generate key set ID when session is initialized
[ Merge of http://go/wvgerrit/16370 ]
Key set IDs are currently generated at different times in the
CdmSession lifecycle. Android generates key set IDs when the license
is received, while the CE CDM generates (or overrides them)
when the session is constructed.
The key set IDs are now generated when the session is initialized.
Key set generation cannot occur earlier as it has a dependency on
security level and in turn on crypto session initialization which
occurs when the session is initialized.
Depenencies on Session ID has caused other activities, construction of
PolicyEngine, CdmLicense, setting property CDM client sets to be
deferred from CdmSession constructor to Init().
Android will still retrieve the key set IDs after the offline license is
processed. For streaming requests, the key set will be
unreserved and discarded when the session is terminated.

* Extend CdmLicense's stored_init_data_
[ Merge of http://go/wvgerrit/14661 ]
CdmLicense will store init data when a server cert must be
provisioned. After provisioning, the original init data can be used
to generate the originally-intended license request.
To do this before, the caller had to call CdmSession's
GenerateKeyRequest with an empty InitializationData object. However,
the init data's type still had to be set, as did the license type.
This CL allows the caller to use a truly empty InitializationData
without a type. To permit this, CdmLicense now stores a full
InitializationData object, rather than just a copy of it's data field.
With this CL, the caller also avoid storing the original license type.
To accomplish this, CdmSession uses the already-set is_offline_ and
is_release_ flags from the original call to reconstruct the intended
license type. The caller uses the new type kLicenseTypeDeferred.
To facilitate storing whole InitializationData objects, they are now
copyable.
This ultimately simplifies server cert code for the new CE CDM.
* Store service certs in Properties
[ Merge of http://go/wvgerrit/14664 ]
This allows CE devices to mimic the Chrome CDM's behavior of sharing
server certs between sessions.
This also affects Android behavior. Previously, provisioned service
certificates were per-session, while explicitly-set service certs
were per-DRM-plugin. Now, both are per-DRM-plugin.
A DRM plugin is associated with a mediaDrm object. Content
providers will still be able to retrieve and use different
certificates. The change here requires an app, that wishes to use
different provisioned service certificates will have to use
multiple mediaDrm objects. This is an unlikely scenario.

* Reject session clobbering.
[ Merge of http://go/wvgerrit/14634 ]
This fixes a bug in I17de92b3e682c9c731f755e69466bdae7f560393 in which
sessions can be clobbered by a forced session ID. This bug manifested
in subtle test failures which involved repeatedly creating sessions.
This was traced to OEMCrypto not being terminated, then upward to a
leaked CryptoSession and CdmSession, and then finally to clobbered
session IDs.
To avoid the bug in future, first, reject duplicate session IDs.
Second, change the OpenSession API to make forced IDs explicit.
* Fix unit test namespaces.
[ Merge of http://go/wvgerrit/14622 ]
This fixes some odd errors that occur when linking multiple test
suites into one executable. When two object files both contain
a definition of wvcdm::MockCryptoSession, for example, one will win
silently and cause the other's tests to misbehave and/or crash.
The solution is to put all mocks into an anonymous namespace, since
each wvcdm::(anonymous)::MockCryptoSession is separate.
In order to avoid lots of repetitions of wvcdm:: in the anonymous
namespaces, all anonymous namespaces in unit tests now live inside
or the wvcdm namespace. This has been done even for tests which
are not currently using mocks.
* Move timer and timer_unittest to Android.
[ Merge of http://go/wvgerrit/14619 ]
These are not used anywhere else.

* Expose release and offline statuses in CdmEngine.
[ Merge of http://go/wvgerrit/14616 ]
This will allow me to make some intelligent decisions in the new CE
CDM implementation without having to duplicate all the information
known in the lower levels.
* Account for backward compat support in tests
[ Merge of http://go/wvgerrit/14621 ]
One test ensures that device path backward compatibility is working,
while another assumes it is used.
This fixes test results when
Properties::security_level_path_backward_compatibility_support()
is false.
Previously, the CE CDM did not run these tests, and so this went
unnoticed.
* Remove Lock::Try, which is not used.
[ Merge of http://go/wvgerrit/14624 ]
Change-Id: Id18cf1f5b18c7322b8b636819276361af225734f
* Move Properties::Init into platform-specific code
This enables a refactor where property initialization for CE CDM will
use values provided by the application during library initialization.
[ Merge of http://go/wvgerrit/14510/ ]
* Add Properties::AlwaysUseKeySetIds().
When true, all sessions will have key set IDs and all session IDs
will be the same as the corresponding key set ID.
This will help the new CDM interface stick more closely to the EME
APIs, in which there are no such things as key set IDs and sessions
only have a single, random ID used for both streaming and offline.
[ Merge of http://go/wvgerrit/14521/ ]
* Reserve key set IDs in memory, rather than on the file system.
This makes it more efficient to use key set IDs for non-offline
sessions.

[ Merge of go/wvgerrit/14240 ]
Client information is reported in release and renewal messages based on
flag in the license. License proto has been updated to match server updates.
There are two caveats
* Client IDs will be reported unencrypted when usage reports are requested.
* Release requests that enable privacy mode (encrypted client IDs) but do not
specify a service certificate are not supported.

This is a merge of several Widevine-side commits that, cumulatively,
allow callers to specify an origin to be used to isolate data storage
as specified in the W3C Encrypted Media Extension specification.
Separate origins have separate certificates, and consequently cannot
share device identifiers with each other.

Add Ability to Check for Existing Certificates
http://go/wvgerrit/13974
Add Ability to Remove the Certificate
http://go/wvgerrit/13975
Make CDM Origin-Aware

This is a merge of http://go/wvgerrit/13693 in the Widevine
repository.
This adds level 3 and mock implementation and unit tests for the
OEMCrypto function OEMCrypto_ForceDeleteUsageEntry. It also plumbs
this function up into CdmEngine, CdmSession, and CryptoSession so that
deleting all usage information for a given app id will now delete the
entries in OEMCrypto, too.

Back when we were being proactive about merging LMP changes to master
in the Widevine repository, there were a few changes that got merged
in a different form than what got checked into the Android repository.
Mostly, this happened due to several large core changes that were
brought over to the master branch in multiple parts so as not to break
other teams using the Widevine repository. This patch brings the two
trees in sync.

This copies over formatting changes from the Widevine CDM repository
that resulted from running clang-format with Google style on the
shared core/ directory. It also copies over some rewordings of log
messages that were made at the same time.
Aside from the changed log messages, this should not affect behavior
or functionality.

The key set ID is now available earlier, in order to support the CE
CDM 4.5 interface, which needs it at key request generation time, not
later at key response receipt time. It is still possible to receive
the key set ID at key response time, for Android's purposes. Either
API may now be passed a pointer to store the ID in, which may also be
left NULL if this is not needed.

Our recommendation to OEMs is that they support a table of at least 50
usage entries in OEMCrypto. If more usage entries are stored, the PSTs get
added to the CDM but are LRU'ed out of the OEMCrypto usage table. When the
CDM queries those usage entries, OEMCrypto will return a
OEMCrypto_ERROR_INVALID_CONTEXT. Rather than return an error and have
MediaDrm throw an exception, CDM should delete this PST and return the
next usage entry, when queried.

* The Usage APIs return usage reports from either L1 or L3 (if available).
* Correction to when usage reports are saved. In addition to other events
they are now saved when keys are loaded, usage reports are released and soon
after first decryption and periodically (60 seconds) after that,
if decryption takes place.
* Usage reports now get deleted on an unprovision request.
* Policy timer is now started when offline licenses are restored.
* Usage session is now released, when a usage response is received.
* Usage tests ahev been enabled.
* Added CDM extended duration (integration) tests to test usage reporting
and querying. These need to be run manually as they take a while (currently
half an hour).
