9729663671 Adjust nonce flood rate in mock oemcrypto
Merge from Widevine repo of http://go/wvgerrit/43721

This CL allows the tester to change the nonce flood rate from the
default of 20.  A tester would want this value to be larger to make
tests run more quickly.

Setting the rate to 1 makes every other nonce request a flood error.
A tester wants to do this in order to verify cdm code responds to
nonce flood correctly.  Several failing oemcrypto tests have also been
corrected.

This CL changes test code only.

aac1439dea Merges to android Pi release (part 12)
These are a set of CLs merged from the wv cdm repo to the android repo.

* 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.

  Bug: 64847919

* 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.

* Add logging for MAC keys to mock

  Author: Srujan Gaddam <srujzs@google.com>

* 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.

* 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

  Author: Fred Gylys-Colwell <fredgc@google.com>

  [ 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.

* Allow some CDM errors to be reported from multiple locations

  Author: Rahul Frias <rfrias@google.com>

  [ Merge of http://go/wvgerrit/38360 ]

  This creates some CdmResponseType errors which may be reused
  PARAMETER_NULL, NOT_INITIALIZED_ERROR, REINIT_ERROR.

  I have made changes to a few classes to report these errors.
  Will work on additional classes in a separate CL.

* 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.

* Use source android level3 + add cache_flush call

  Author: Srujan Gaddam <srujzs@google.com>

  [ Merge of http://go/wvgerrit/37900 ]

  I put both changes in this CL since I have to generate Level3 libraries
  for both anyways. The first change involves shifting from using a
  prebuilt static library to using an obfuscated source library output
  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
  execution on Angler gave inconsistent segfaults, which this CL fixes.

  Verified on Angler, Sailfish, and Linux.

  11/27/17: Added mips and mips64 libraries.

* Make CDM result codes constexprs

  Author: Rahul Frias <rfrias@google.com>

  [ Merge of http://go/wvgerrit/38280 ]

  The values in the enumeration list of CdmResponseType error codes
  were earlier implicit. Comments were added to denote the actual
  values. This changes to make it fixed values, which makes it slightly
  more error prone, but cleaner when errors are retired.

* Change watchdog timer to 2 minutes

  [ Merge of http://go/wvgerrit/36340 ]

  This relaxes the watchdog timer around the level 3 oemcrypto
  initialization to 120 seconds.  There are also a couple of new log
  messages at the end of initialization and at termination.

* 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.

* 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.

* 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.

  [ Merge of http://go/wvgerrit/32700 ]

  Use of EVP_CIPHER_CTX requires a call to EVP_CIPHER_CTX_cleanup().

* Memory leak in OpenSSL RSA key handling.

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/32621 ]

  This fixes a range of tests. --gtest_filter="CdmDecrypt*" runs
  five tests and still loses 5 objects totalling 1320 bytes (down
  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 "_".

  [ 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.

* 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.

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

  This CL adds a new variant of the OEMCrypto mock code that adjusts its

  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.

On some platforms, the compiler will not pack structures.  This CL
replaces the OECrypto_PST_Report packed structure with a simple buffer

There is also a new wrapper class that test code, the mock, and debug
code can use to access data in the report.

The old packed structure definition is moved to the level 3, where we
use a compiler that packs sructs when asked nicely.

d30c5f8d33 Break Decrypt Buffers Into 100KiB Blocks As Needed
(This is a merge of go/wvgerrit/22949)

Starting with OEMCrypto v12, we are guaranteeing to integration partners
that the buffers passed to OEMCrypto_DecryptCENC and
OEMCrypto_CopyBuffer will not be more than 100KiB (102400 bytes) in
size. For requests larger than this, we will first try to send the
buffer to OEMCrypto anyway. (in case the integration supports buffers
larger than the minimum) In the event that the buffer is rejected, we
will break it up into 100KiB chunks and send them down individually for
decryption.

Breaking a subsample into smaller subsamples necessitates knowledge of
how to update other decryption parameters (like the offsets and the IV)
that previously the CDM Core has not needed to know about. Until now,
this knowledge lived in the glue layer on the Android CDM and nowhere
on the CE CDM. Now, the CryptoSession has a subset of this knowledge, in
order to break up buffers successfully.

For testing purposes, the Mock OEMCrypto has been modified to only
support the smallest buffer size. In order to make sure the chunking
code was being exercised by them, the CE CDM tests had to have the
amount of data they decrypt increased by several orders of magnitude. To
contain this growth, I have moved the test data to its own file.

Bug: 31381719
Test: Ran the updated CE CDM integration tests
Test: Modified the OEMCrypto dynamic adapter to pretend both L3 and L1
only support 100KiB buffers on a Marlin and a Ryu. Confirmed that the
GTS H.264 tests (which have subsamples over 100KiB) passed still. A
similar test was attempted on Fugu but Fugu cannot pass these tests even
without this change present.

914e13067f Add Support for Baked-In Certificates
Port from the widevine repo of http://go/wvgerrit/15628

This change enables easy support for baked-in certificates. Platforms
using this feature need only change the supports_keybox property to
false, replace keys.cpp with the file provided by Google, and make
sure the cert.bin provided by Google is preinstalled in the storage.

To enable this, new files defining storage for the embedded private
key were added to MockOEMCrypto. When supports_keybox is false, these
are referenced to get the embedded private key. As this code is mostly
shared with the existing test utility function that loads the test
certificate, the shared code was moved to a helper. Also, the behavior
of the MockOEMCrypto implementation OEMCrypto_LoadDeviceRSAKey when
supports_keybox is false was changed from erroring to validating that
the "wrapped private key" is actually the magic value 0xDEADBEEF.

92958a0e6a Protect OEMCrypto Mock and Level 3 From Null Pointers
Merge from widevine repo of http://go/wvgerrit/14502

If any OEMCrypto session call is made after Terminate is called, then
there was a null pointer access.  This is protected by the oemcrypto
adapter, but could still be a problem in unit tests which by-pass the
adapter.

6d5be4fddf Enable OEMCrypto Unit Tests
This is a merge from the widevine repository of
http://go/wvgerrit/13923 Switch openssl to use the EVP interface for aes-ctr-128
http://go/wvgerrit/13979 Add Test Certificate to OEMCrypto Mock
http://go/wvgerrit/13978 Add Test Keybox to Level 3 OEMCrypto
http://go/wvgerrit/13873 Enable OEMCrypto Unit Tests

This CL adds a main program to oemcrypto_test.cpp, which filters out
tests that are not supported on the specified platform. It also adds
LoadTestKeybox to the mock. This allows oemcrypto unit tests to be run
on devices that have production keybox.  It also allows the same set
of unit tests to work on Android and on non-Android platforms.

ae1711acc0 Add backward compatibility to OEMCrypto_CopyBuffer
Merge from Widevine repository of http://go/wvgerrit/13912

This CL falls back to OEMCrypto_DecryptCTR if the oemcrypto library
does not implement OEMCrypto_CopyBuffer.  This allows devices with
oem crypto version 9 to function as they previously did.

7b262e1d02 Alphabetize & Googleize Header Inclusions
(This is a merge of http://go/wvgerrit/13761 from the Widevine
repository.)

This cleans up our includes to be in Google Style Guide order and in
alphabetic order, for the parts of the code that are expected to
follow Google Style.

This also converts places in our code that were including C headers
in the C++ style (i.e. <cstring> instead of <string.h>) to use C style
instead. This is because, although it was not causing problems for us
yet, on Android these actually include different headers. (<cstring>
is provided by libcxx, while <string.h> is provided by Bionic)

Lastly, this change puts all headers that do not come from within our
project in <brackets> instead of "quotes," which was not being done
consistently.

This change is explicitly NOT trying to standardize the spacing of our
header includes. I have tried to respect, in each file, the spacing
style already present.

047f543e7c Improve OEMCrypto unit tests
This is a merge of http://go/wvgerrit/13701 and http://go/wvgerrit/13780.

I added a new set of engine properties for the mock oemcrypto.  This
set pretends to be level 1. This allows the widevine build bot to test
the dual security level path: a level 1 liboemcrypto.so and a fall
back to L3.

I also adjusted the failing test in oemcrypto_test.cpp.  A correct fix
requires us to rewrite some of the oemcrypto mock code so that it
returns real error codes instead of just 'false' on error.

d2ba3a3f91 Allow selective removal of Usage Table Entries by PST
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.
