6f3e866882 Pack structure OEMCrypto_PST_Report
Because the OEMCrypto_PST_Report is sent as a signed block to the
server, it needs to be a fixed, platform independent, size.  This CL
adds the packed attribute to the structure, which reduces its size
from 56 bytes to 48 bytes.

8c73bde53f Add password to prevent vendors from editing CENC pdfs.
What can the user do with the security setting:
 - open and view the doc
 - print the doc
 - no copying of content
 - can add comment, filling in forms and signing existing signature fields
 (no forms or signature fields in the doc),this option is bundled together
 (it is nice to allow the user to add notes to the doc)

1cd8195d88 OEMCrypto Usage Tables
This CL adds usage tables to the OEMCrypto reference implementation
(mock) and unit tests.

There is also a new parameter called oem_crypto_require_usage_tables
that determines if the usage tables are required or not.  This is set
to true for Android and false for all other platforms.

This CL is most of OEMCrypto version 9 updates.

026a04701e Test Key Control Block with HDCP Version
This is a copy of the Widevine CL:
https://widevine-internal-review.googlesource.com/#/c/9480/

This change is part of OEMCrypto API version 9.

This CL adds verification that a key control block which requires a
specific version of HDCP can be loaded.  Also, if secure data path is
not set, it verifies that data is still decrypted.

This CL also adds test that verify DecryptCTR fails when the current
HDCP version is below that in the key control block.  The expected
error is OEMCrypto_ERROR_INSUFFICIENT_HDCP.  This error code is newly
introduced in this CL.

This is one attempt to clarify HDCP, as specified in b/13626021, and
is a slight modification from previous behavior for the mock and the
level 3 haystacked code.

This CL also tests the two valid verification codes "kctl"
and "kc09".

b2af1e6303 OEMCrypto Version 9 API (KLP Modular Version)
This CL changes the header file and documentation for OEMCrypto
version 9.

It is a cherry pick of Change-Id: I1a43a686ef5d345132affc672bc1c6acf7b3f661

I modified the reference implementation and the calling functions just
enough that existing unit tests still pass.  Acutal implementation of this
API will be in future CLs.

Comments on the documentation can be made in the Google Doc here:

adfd599175 Remove external links from PDF documents.
A bug (b/8132682) in "Download as PDF" from Google Docs makes table of
contents links point back to the original document.  This causes
problems with external customers.

This change uses the following work around: print the document, and
select "Save as PDF" as the printer.

This only removes the links.  It does not fix them.  When bug 8132682
is fixed we can re-download the documents with proper links.

9fdeabe3ed Update Widevine Modular DRM Integration Guide
The function OEMCrypto_LoadKeys should accept a null pointer for the
enc_mac_keys pointer.   This indicates that the mac_keys are not being
updated. This CL just updates the documentation to clarify this behavior.

5d7ac644c5 Disable OEMCrypto tests that install a test keybox.
Because we do not want to accidentally install a test keybox on a
production device, most of the oemcrypto unit tests are being disabled
by default.

If you wish to run these tests, you can override this choice, by
running:
adb shell /system/bin/oemcrypto_test --gtest_also_run_disabled_tests

This change prompts for and requires positive confirmation before
running the disabled tests on a device that has a non-test keybox
already installed.

3342e33143 Resize signature buffer
There is an ambiguity in the use of the signature length in
OEMCrypto_GenerateRSASignature.  If the pointer to the vector is null,
the function should set the length parameter to be the size of the
buffer needed.

This ambiguity has been clarified in the documentation: the
length returned should be the exact length of the buffer.  It
will be corrected in a future release of Qualcomm's L1.  However,
we are putting this change in both as a stop-gap and as a
belt-and-suspenders fix.
