ce25b9d44c Avoid null dereference with empty BCC strings.
[ Merge of http://go/wvgerrit/168482 ]

The function OEMCrypto_GetBootCertificateChain() does not always
provide an additional signature depending on the device.  However, the
CDM would still attempt to dereference the first character in the
additional signature buffer when empty.  This CL changes how the data
pointer to an output string is acquired.  Empty string will instead
pass in a null pointer.

340810f77f Remove hash algorithm from renewal requests
(Merged from http://go/wvgerrit/165859.)

Since renewal requests are signed with the MAC keys and not an
asymmetric key, it does not make sense to query OEMCrypto for the
asymmetric key hash algorithm nor to include the result in the renewal
request.

1603ba127f Renaming of Usage Table related variables and types.
[ Merge of http://go/wvgerrit/164077 ]

This CL makes major changes to the names of variables and types that
are related to the usage table, header, entries, entry indexes, and
other related data.

The renaming followed these rules:
1)  "Usage table header" will exclusively refer to the header blob
    that is OEMCrypto specific.  The CDM class "UsageTableHeader"
    is the CDM-layer's abstraction around the "usage table" concept.
    The name has been updated to reflect that.
2)  The "Cdm" prefix is only used for the CDM-specific data types for
    the usage table and entry info.  It has been removed from
    OEMCrypto-specific types.
    - UsageTableHeader -> CdmUsageTable
    - CdmUsageTableHeader -> UsageTableHeader
    - CdmUsageEntry -> UsageEntry
3)  The "usage_" prefix has been removed from variables when the usage
    table or usage entries are the subject of the function or class.
4)  UsageEntryIndex is the type for entry indexes, instead of directly
    using uint32_t.  This matches how we wrap other types in
    "wv_cdm_types.h"
5)  Changed entry "number" to entry "index".
6)  Vectors of elements have been renamed to be either pluralized or
    have a suffix "_list".
7)  "Usage info" was occasionally being used to refer to the usage
    table or entries generally, rather than specifically secure-stop.
    - CryptoSession::HasUsageInfoSupport() -> HasUsageTableSupport()

The most major change is that the files "usage_table_header*" have
been renamed to be "cdm_usage_table*".

b26126d3aa CDM Core: Removed support for v15 licenses.
[ Merge of http://go/wvgerrit/160000 ]

OEMCrypto v15 licenses made use of several now-obsolete API functions
of OEMCrypto (mainly LoadKeys and RefreshKeys).  All license handled
by the CDM must be v16 or newer.  The CDM can now rely on all license
requests/responses containing a core message, using v16 policy timers,
and requires loading using LoadLicense() / LoadRenewal().

bcb04e050e Clean up constexprs with extra consts
(This is a merge of http://go/wvgerrit/151930.)

While grepping the code to respond to some CR feedback, I noticed a few
places where we had sprinkled some unnecessary "const" specifiers
amongst constexpr declarations. This patch cleans them up. There should
be little semantic difference in the code after this patch, as it only
removes specifiers that were redundant. The only exception is where
"constexpr const char* X" was converted to "constexpr char X[]", which
has slightly different semantics in edge cases we don't use.

9d169a00bb Move system ID extraction outside of CryptoSession.
[ Merge of http://go/wvgerrit/151391 ]

This CL moves the logic for extracting the system ID from keybox or
OEM certificate (from OEMCrypto or device files) to a dedicated
SystemIdExtractor.

Before Provisioning 4.0, the system ID could only be found from data
returned by OEMCrypto.  However, with provisioning 4.0, the system ID
can now be found in the OEM certificate that is stored on the device
files.

1069ae39cc Resize OEMCrypto buffer-based results on success.
[ Merge of http://go/wvgerrit/151191 ]

Within the CDM and OEMCrypto tests, there were a few OEMCrypto function
calls where the final size of the output buffers were not being
resized.  For several of these functions, an initial call is made with
zero-length output buffers, expecting OEMCrypto to return
ERROR_SHORT_BUFFER; followed by a call with buffers at least as large
as specified by OEMCrypto.  However, for some operations, OEMCrypto
makes an estimate on the final size on the first call, specifying the
exact size only after performing the operations.

This is the case for the wrapped key returned by
OEMCrypto_LoadProvisioning().  The provisioning response contains a
padded + encrypted DRM key.  OEMCrypto does not know the actual size
of the key until decrypted, and the actual DRM key might be smaller.

There was a OEMCrypto test for OEMCrypto_BuildInformation() which
was enforcing the wrong behaviour.  This has been updated.

f696a48318 Logging CDM session ID on Decrypt() failures.
[ Merge of http://go/wvgerrit/149690 ]

This changes extends the CryptoSession logging to include the OEMCrypto
session ID in its decrypt failure logs, and adds a new CdmSession
decrypt failure log which includes the CDM session ID.  The CDM session
directly maps to the MediaDRM session ID, making app debugging easier.

The Decrypt() code pathway is one of the most frequently called
portions of the CDM code, and the pathway attempts to make as few
logging calls as possible in order to keep latency low and log
verbosity to a minimum.  It is anticiapted that when a call to
Decrypt() fails, there will be a burst of failures as the app may
make several calls to Decrypt() before handling the first decrypt
error.

To keep logging low, the following rules are followed:
- CryptoSession: decrypt errors are only logged when the decrypt error
  changes.
- CdmSession: decrypt errors are only logged when the last call to
  decrypt had succeeded.

97f3544866 Added CDM support for Watermarking reporting.
[ Merge of http://go/wvgerrit/148552 ]

Extended the CDM layer to report OEMCrypto's watermarking support.
The reporting of watermarking comes in three (3) mechanisms:
1) ClientCapabilities in license requests
2) CryptoSession metrics when queried to OEMCrypto
3) String property query by apps

If OEMCrypto implementents OEMCrypto_GetWatermarkingSupport(), then
the reported watermarking support by the CDM will match that of
OEMCrypto.

If OEMCrypto does not implement OEMCrypto_GetWatermarkingSupport()
or an error occurs, it is assumed that OEMCrypto does not support
watermarking, and the CDM will report "Not Supported".

OEMCrypto_GetOEMPublicCertificate is only applicable to

keyboxes (or BCC) as their RoT would return a spurious
error OEMCrypto_ERROR_NOT_IMPLEMENTED. Removing the call

[ Cherry-pick off http://ag/16624952 ]

Devices without a keybox may not have access to a device ID if the OEM
uses the device ID from the keybox as its source of truth.  For
devices which have lost their keybox, OEMCrypto_GetDeviceID() was
assumed to return ERROR_KEYBOX_INVALID if that was the case; however,
Qualcomm's implementation was returning ERROR_NO_DEVICEID.  Given that
both error codes are appropriate, the CDM has been updated to accept
both as an indication that the device ID cannot be retrieved, and that
the null device ID should be returned.

Merge from Widevine repo of http://go/wvgerrit/135984

If the MediaDrm property string debugIgnoreKeyboxCount is set to 1,
then the keybox will be ignored on the next initialization. This will
force an OTA keybox reprovisioning.

Equivalently, a 1 may be written to the file
L1/debug_ignore_keybox_count.txt.

In order to test a failed reprovisioning step, a value of 2 may be
used.

Extended the functionality of the CdmEngine to check if the device
requires OKP and to initialize OKP resources if required.  The
functionality of OpenSession() and GetProvisioningRequest() have been
the most affected.  If OKP is required, these methods will signal to
the app that provisioning is required and will return an OKP request.

Once a device is provisioned, the OKP data is cleared away and the
CdmEngine will resume normal operation.  Engines created after a
device is provisioned will immediately enter normal operations.
The exception is for CdmEngines which failed to perform OKP for some
reason and are still running.  Those apps will need to restart before
gaining access to L1 operations.

http://go/ag/14812524

The keybox validation needs to be done separately from initializing
the library so that we can support Keybox OTA Reprovisioning.

If L1 loads, but the keybox is missing, the initialization should
succeed. When the keybox is validated, the adapter should try to look
for a keybox on the filesystem. if none is found, it should either
return NEEDS PROVISIONING or an error.

1447eba7bc Fix -Wshorten-64-to-32 errors in usage table code
(This is a merge of http://go/wvgerrit/134312.)

This patch fixes code that would trigger -Wshorten-64-to-32 by
implicitly narrowing a variable from 64 to 32 bits. Most of the time, it
does this by making the implicit conversion explicit. There are a lot of
these places in the usage table code because we always use uint32_t as
the type of a usage entry index, but much of the code that interacts
with the usage table system naturally wants to use size_t.
