repo.
* Android build fixes

[ 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.
Author: Thomas Inskip <tinskip@google.com>
[ Merge of http://go/wvgerrit/36141 ]
* Send cdm test requests to UAT.
Author: Jeff Fore <jfore@google.com>
[ 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.
* Finalize merge of cdm_partner_3.4 to master.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/35360 ]
This is the final set of updates to merge all v3.4.1
changes into master.

* Resolve intermittent decrypt error.
Author: Jeff Fore <jfore@google.com>
[ Merge of http://go/wvgerrit/35720 ]
The CdmSession's closed state was not properly
initialized resulting in intermittent
SESSION_NOT_FOUND_FOR_DECRYPT errors.
In CdmEngine::Decrypt the session is looked up by
the key id. A list of open sessions is acquired
by calling CdmSessionMap::GetSessionList and each
session in the list is queried to see if it has
the key.
In building the list in CdmSessionMap::GetSessionList,
sessions are only added to the query list *if* the session
is not closed.
The closed status was not initialized and during testing
the query list would not contain the session causing
CdmEngine::Decrypt to return SESSION_NOT_FOUND_FOR_DECRYPT
resulting in the ce cdm api returning widevine::Cdm::kNoKey.
* No support for pre- C++11 compilation.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/35381 ]

The pointer points into a message and it may not be aligned.
Always copy the nonce into aligned memory before checking it.

* Compiler strictness: more checks and code cleanup.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/35300 ]
Use the switches proposed in b/38033653 (as much as possible - some
conflicts with protobufs and gtest prevent fully accepting them).

from 6200 bytes).
* Unit test and mock OEMCrypto memory leaks.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/32640 ]
More memory leak cleanup. All remaining leaks are due
to calls to CRYPTO_malloc() without the matching free
(i.e., calls into openssl).
* 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
generic_crypto_unittest tests for FileSystem object 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 "_".
* Usage license handling corrections
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/28540 ]
Validate that offline licenses that do not contain a provider session
token are not handled by the TEE.
BUG: 38490468

* 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.
* Address compilation issues
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/28740 ]
These changes enable compilation of most of the cdm code on android
expect for OEMCrypto unit tests (b/62739406) on wv master.

Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/28074 ]
Property is "provisioning_messages_are_binary". Its default setting is
false in the CE CDM, but it can be overridden by integrators.
Added section to integration guide that discusses Provisioning Server
message formats and the new property.

New status code is kKeyUsageBlockedByPolicy. It is returned by the decrypt()
call instead of kDecryptError or kNoKey.

* Update service certificate.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/28065 ]
The updated service certificate fixes a number of failing tests.
There are still some that fail, apparently due to mismatches
with key set IDs and usage tables.
Also updated QA server URL to point to QA proxy (although neither
can be used by this client).
Also fixed segfault in CdmTest.ListUsageRecords.
* Add CDM APIs for Handling Service Certificates.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/28064 ]
The responsibility for managing Service Certificates has been moved
out of the CDM. Instead, provide CDM and CdmEngine methods to generate
a service certificate request message, and handle a service certificate
response. The API client can use these calls if it needs to get the
service certificate from the License Server.
These functions assume the request and response are base64 (web-safe)
encoded (see b/37481392). Not all servers are operating this way yet.
Any adaptations for non-compliant servers is handled outside the CDM.
See test WvCdmEnginePreProvTest::ServiceCertificateRequestResponse in
cdm_engine_test.cpp for an example of this.
These changes also eliminate the stored init_data and deferred
license type which were used to perform a service certificate request
during a license request.
* Fix and rename ClosesSessionWithoutReturningError test.
Author: Edwin Wong <edwinwong@google.com>
[ Merge of http://go/wvgerrit/27880 ]
ClosesSessionWithoutReturningError should not check for
Status::OK since it is expecting an error code back.
The test is renamed to ClosesSessionWithError.

BUG: 62205215
* Get rid of default service certificate.
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/27981 ]
Instead, we need at least two service certs - one for the QA/Test
servers, and one for UAT (and prod?)
There are still some issues around the signature verififcation
of the service cert, and in license_unittest.cpp, the use
of the default service cert has been commented out. I don't know
why this test needs a service cert. If it really does, then the
same mechanism that is used elsewhere for selecting a specific
server type will be needed here.

* Fix handling of OEM Cert public key.
Author: Srujan Gaddam <srujzs@google.com>
[ 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.
This also fixes a problem where the public cert string was
not being trimmed to match the size returned by
OEMCrypto_GetOEMPublicCertificate().
* Complete provisioning request/response for Provisioning 3.0
Author: Gene Morgan <gmorgan@google.com>
[ Merge of http://go/wvgerrit/27780 ]
Fix bug on provisioning request path where GenerateDerivedKeys()
was being called when preparing to generate the signature.

* 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.

In OEMCrypto version 13, usage information is updated by calls to

OEMCrypto version may vary by device.
This consolidates calls to OEMCrypto_UpdateUsageTable so that they
can be disabled if OEMCrypto version >= 13. No functional changes other
than disabling by OEMCrypto version were introduced in this section.
Helper routines have been added to device files as well.

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.

(This is a merge of http://go/wvgerrit/31040)
Because the Policy Engine was only consulting the result of the Max-Res
Decode check when it was in kLicenseStateCanPlay and not in other states
that imply kKeyStatusUsable, like kLicenseStateWaitingLicenseUpdate, the
Max-Res Decode results would not be honored during the interval between
requesting a renewal and receiving the result. (Or until the key
expired.) This was particularly problematic for keys with renewal delays
less than ten seconds long, which would freeze the Max-Res state before
it had a chance to update for the first time, effectively disabling
Max-Res Decode until renewal was received.
Fixing this required changing how the Policy Engine and the
LicenseKeyStatus objects communicate about the changing usability state
of the LicenseKeyStatus objects. Before, a call to ApplyConstraints()
might calculate a Max-Res failure, but this failure would be pending
until the Policy Engine deigned to call ApplyStatusChange() again.
Without a call to ApplyStatusChange(), it could pend forever. This put a
burden on the PolicyEngine to poll the LicenseKeys with redundant
ApplyStatusChange() calls using the same CdmKeyStatus that the keys were
already in, just in case Max-Res had changed since the last necessary
call to ApplyStatusChange().
If the Policy Engine got the timing of these calls wrong, it would
result in Max-Res results being ignored. (as in the linked bug) If it
ever polled with the wrong CdmKeyStatus, it would update the
LicenseKeys' status when it did not mean to. It would be preferable if
this polling were not needed, so that the Policy Engine couldn't get it
wrong.
This patch changes the API between these classes so that when Max-Res
fails, the state change can be reported immediately instead of pending
until ApplyStatusChange() is called, eliminating the need for polling.
All state changes to the LicenseKeyStatus objects go through a unified
ApplyStatusChange() method that can update the CdmKeyStatus, resolution,
and/or HDCP level and report any resulting usability changes
immediately. This patch updates the unit tests to exercise this new API
instead of the old API.
Previously, the linked bug slipped past our unit tests because we only
test unrenewable, streaming licenses against Max-Res. This patch adds
several more variants to
policy_engine_constraints_unittest so that it tests six kinds of
license to provide better coverage.

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.

* 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.
* Addresses failures with request_license_test with secure stop in L3.

These tests verify whether a L3 device respects the HDCP policy set in the
license request. L3 device should only play the clear lead, and stop at
encrypted content. MeidaDrm should throw an ERROR_INSUFFICIENT_OUTPUT_PROTECTION
exception. This is because L3 device always returns current HDCP connection
status as HDCP_NONE.
This CL modifies the policy engine CanDecryptContent method to return
CdmResponseType instead of a boolean, so the app can generate the correct
error response if HDCP constriants are not met.

Provisioning 3.0 devices that do not use SPOIDs have been returning
their full OEM Public Certificate as their device ID. While this is not
a security concern, (it is a PUBLIC cert) the cert is many times larger
than applications are likely expecting. (several kilobytes vs. just a
few bytes) This patch hashes the OEM Public Certificate to produce a
smaller value, but only when it is being provided out of the CDM to a
caller.

In OEMCrypto version 13, usage information is updated by calls to
OEMCrypto_UpdateUsageEntry. In previous versions calls were made to
OEMCrypto_UpdateUsageTable instead. Both need to be supported as the
OEMCrypto version may vary by device.
This consolidates calls to OEMCrypto_UpdateUsageTable so that they
can be disabled if OEMCrypto version >= 13. No functional changes other
than disabling by OEMCrypto version were introduced in this section.
Helper routines have been added to device files as well.

The UsageTableHeader class is a singleton that CDM sessions will share.
A separate object will be created for each security level. The class
synchronizes access to usage table header and associated data-structures
and controls when they are read in or written out to non-secure persistent
storage. Upgrades from a fixed size usage table (supported by previous
versions of the OEMCrypto API v9-12) are handled by this class.

In OEMCrypto V13, usage table header and usage entries are stored in
persistent non-secure storage and loaded and unloaded from the TEE.
Information needs to be maintained to assist finding the associated license
or usage information. This information has been revised for usage information
to use key set id and usage info file name rather than provider session
token and app id.
The app id is stored in a hashed form (usage info file name) and was not
extractable during the upgrade process to OEMCrypto V13. Due to this
DeviceFiles UsageInfo routines have switched to use usage info file name
rather than app id as a key.
