147c9e0afa Log X-Google fields on failed HTTP requests.
[ Merge of http://go/wvgerrit/103395 ]

To help with debugging failures in HTTP requests during unit tests,
this CL adds logging for Google's debugging response header fields.
These fields are of the type "X-Google-*" or "x-google-*" and provide
information such as the service name, server cell, error details, and
other details that can help isolate the cause of failure on the
server's end.

An additional unittest has been created to test the parser for the
header fields.

Tests that are known to exprience HTTP failures have been extended
to include logs for these fields should they be present.

99335a6aa8 DO NOT MERGE Handle unlimited usage table capacity.
[ Merge of http://go/wvgerrit/103684 ]
[ Cherry pick of http://ag/12221244 ]

The OEMCrypto method for usage table capacity can return zero to
indicate that the usage table size is not explicitly limited.  The
CDM must handle this case with regard to the CDM's usage table
management and information querying.

The usage table initialization tests are extended to include cases
where the table does not have a defined limit.

AddEntry() was missing call to update the usage table header after
creating a new usage entry.  This call is now included and required
additional changes to the usage table unit tests.

3709a4f419 Allow offline licenses to be loaded and restored in the same session
[ Merge of http://go/wvgerrit/103243 ]

In v16, OEMCrypto specifications required that an error be returned if
multiple attempts are made to load an offline license into a session.
This caused the GTS test testConcurrentDrmCertificates to fail. It was
introduced to verify that a license could retrieved and loaded into a
session and then restored. This was based on an app use case.

Ideally we would like to disallow a this behavior but need to make sure
it is not being used by apps.

For now this will be allowed. If detected, the CDM will reintialize the
OEMCrypto session and allow the license to be restored.

b90f88072f Start rental clock when nonce-free offline license loaded
Merge from Widevine repo of http://go/wvgerrit/103107

When an offline license is reloaded, if it does not have a usage entry
to indicate when the rental clock was started, the start time defaults
to 0 in the ODK library (in OEMCrypto). This CL changes the code to
start the rental clock in this case. It does this by signing a dummy
message, which triggers the ODK library to start the rental clock.

7f347cd59f Adjust nonce for v15 servers
Merge from Widevine repo of http://go/wvgerrit/102783

When OEMCrypto is v16, but the license server is v15, we should not
create a new nonce for a license renewal. However, the request does
need a nonce or the license server will not generate a valid key
control block. So we should use the nonce that came from the original
license.

7ce8950c0f Usage table LRU only retrieves a single entry.
[ Merge of http://go/wvgerrit/102167 ]

After changes made to how the usage table is defragged by the CDM,
it was determined that there is no use in selecting more than a single
entry from the usage table to evict.  The only failure that can occur
when evicting an entry is if the last entry is in use, in that case,
evicting other entries will still result in a failure.

This change cleans up the LRU algorithm and test cases to reflect
the new functionality.

Several tests that make parallel license requests were disabled due
to a flaky server failure unrelated to CDM code.  Most of these tests
are now re-enabled to ensure the multi-threaded license requests is

These tests remains disabled for L3 due to continued flakiness.

John W. Bruce
804c0d470c Rework Device File Matchers to Avoid Buffer Overflow
(This is a merge of http://go/wvgerrit/102104)

The device file unit tests use some custom matchers that were written
back when we didn't have C++11. Because gMock requires std::tuple to
pass a pointer AND a length to a matcher, these matchers had to estimate
the length of the file. This technically meant they were causing a
benign buffer overrun sometimes.

Since we have C++11 now, we can fix this by using a matcher over a
std::pair of the pointer and length. I also took the opportunity to
refactor the matchers a little. The old matchers had many very specific
overloads and also collided with the names of some standard gMock
matchers. Now there are just two more-general matchers with unique
names.

6a247ab924 INSUFFICIENT_RESOURCE errors are mapped consistently.
[ Merge of http://go/wvgerrit/102109 ]

The CDM was using unique CDM error codes for the various cases
where OEMCrypto would return INSUFFICIENT_RESOURCE.  However, these
error codes were being incorrectly mapped at the Android level,
resulting in incorrect errors in the MediaDRM layer.

At no point does the CDM handle different INSUFFICIENT_RESOURCE_x
within the same case, as such the use of unique codes are limited.
This CL removes the unique codes, and unifies them under the same
CDM error code.

This CL also extends SelectKey to handle error codes returned by
LoadEntitledContentKeys.

bbe9f6afc4 Add ATSC support - part 1
[ Merge of http://go/wvgerrit/100864 and http://go/ag/10704773 ]

ATSC 3.0 allows for licenses to be downloaded OTA and are tied to
a DRM certificate that may be shared across apps. The provisioning
process for ATSC may happen at the factory or during an OS update.

This contrasts from the regular OTT model, which requires that
provisioning and license download have an uplink as well as a
downlink connection.

This adds support for the ATSC mode property. ATSC mode can only be
set (or unset) before sessions are opened. Once the CDM identifier is
set/sealed, requests to modify the ATSC mode will be rejected.

If one needs to open sessions with both ATSC mode and regular (non-ATSC)
mode, separate MediaDrm objects will need to be created. The default
mode is to not use ATSC.

Enable ATSC mode by calling
  mediaDrm.setPropertyString("atscMode", "enable")

Disable ATSC mode by calling
  mediaDrm.setPropertyString("atscMode", "disable")

Provisioning and unprovisioning requests for ATSC will be rejected as
certificates will be retrieved by the ATSC service.

bdd7b9d89f Allow CDM to Build With Recent GCC
(This is a merge of http://go/wvgerrit/100051. However, only one part of
that change affects the Android code, so I have filtered this
description.)

By default, the CDM builds with Clang on Android and on developers' dev

However, recent versions of GCC were refusing to build our code for a
variety of reasons. This patch fixes the codebase up so that the
version of GCC 9 included on gLinux workstations can compile the CDM.

The only change that affects Android is that a variable was being set
but never read in one place.

When processing a license release, the license is not loaded, so

This CL also adds some extra logging to tests so that we can track
content id and the pssh. This CL also updates some of the test content
policies when running the local license server. The local license

[ Merge of http://go/wvgerrit/96071 ]

Changes to how the usage table method InvalidateEntry() behaves
required additional changes to CDM code that uses this method.

This involved some refactoring to AddEntry(), moving the LRU
related code to its own function.

A few unittests had to be changed / removed as the moving
multiple entries changes expectations of several existing tests.

Several additional helper methods have been created to improve
readability.  These include getters for information about the
usage table, a method for releasing stale entries, and a method of
recording LRU metrics.

da48461ba2 Reworked DeleteEntry() into InvalidateEntry().
[ Merge of http://go/wvgerrit/95406 ]

There was an issue with DeleteEntry() where it would result in an
invalid table state if shrinking the usage table when the number of
sessions is at its max.

This required changing how the usage table invalidates entries.  Now,
after invalidating an entry (marking an entry as kStorageTypeUnknown)
the table is defragmented if specified to.

Defragmentation involves:
1)  Move valid entries near the end of the table to the position of
    invalid entries near the front of the table.
2)  Shrinking the table to cut off trailing invalid entries.

This change updates the existing tests to pass, but still needs new
tests for some of the edge cases.

2a16d70a06 Suppress error for removing lingering offline licenses.
[ Merge of http://go/wvgerrit/97963 ]

There are situations where an offline license file will remain on the
system after it's usage entry has been deleted.  This would result in
its key set ID being reported as present by the CDM, but any
operations acting upon it will result in an error.

The app should be able to remove the license without error, so long
as the license file exists and no other OEMCrypto operations fail.

This change introduces a new error code LICENSE_USAGE_ENTRY_MISSING,
which indicates that a license's usage entry cannot be found.

A new integration test checks that the CDM can handle the calls to
removeOfflineLicense().

e27bc4ba6a Accept a security level to be specified during provisioning
[ Merge of http://go/wvgerrit/97267 ]

In earlier releases, provisioning would occur based on a cached
security level. If an open session call returned a NotProvisionedException
the security level would be cached for use with any future provisioning
call.

An app would have to set the security level, then call openSession,
have it fail and then request provisioning. This fits the normal flow of
most apps. Still on occasion, an app might change requested security level
after an openSession call failed. Using the cached security level
would result in unexpected behavior.

This change allows provisioning to occur at the last security level that
was set.
