44d2d2653e Delete old provisioning doc
Merge from Widevine repo of http://go/wvgerrit/53980

The provisioning doc changed names, and I accidentally added the new one
without deleting the old one.

I also added a watermark to the newer one.

a20034e3a2 Recover when stored information is corrupted
[ Merge of http://go/wvgerrit/52040 ]

Information stored in files are serialized and protected by an MD5 hash.
When files cannot be read because the MD5 hash computed over it
fails verification, the file is deleted. This allows for recovery.

However if the protobuf deserialization fails we return an error
but do not delete the file. When errors of this sort occur
with usage information files, the CDM cannot recover.
removeAllSecureStops() will fail as well and new licenses
with PSTs cannot be processed. In order to recover the file will
be deleted when a protobuf deserialization error occurs.

b305d99d3b Make Defensive Copies in CopyBufferInChunks
(This is a merge of http://go/wvgerrit/51084)

Nominally, OEMCrypto probably shouldn't modify the buffer descriptor we
pass into OEMCrypto_DecryptCENC(), but in practice, we know some
platforms do this, so we make defensive copies in
CryptoSession::DecryptInChunks() just in case. Turns out, some devices
also behave like this in OEMCrypto_CopyBuffer(), so we should also be
doing defensive copies in CryptoSession::CopyBufferInChunks().

e8c3a4afac Protect sessions from concurrent access.
Locks in earlier releases controlled access to sessions and the list
of sessions for each CdmEngine instance. This guarded against
concurrent access between session management (OpenSession,
CloseSession, etc), periodic timer calls and calls to Decrypt.

The list of sessions and locking was moved to a separate class
CdmSessionMap. This left open the possibility that a session
might be destructed, while being called to decrypt or invoked through the
timer. An attempt was made to add per-session locks in b/73781703
but this was found insufficient.

Per-session locks will be introduced in a future changelist, but for
now the coarser locks will be reintroduced.

dcab2b1355 Address concurrency failures between calls to decrypt and periodic timer
[ http://go/wvgerrit/50341 ]

The shared_ptr implementation was taken from a google3 implementation.
Updates to the reference counter needed to be atomic and were
platform dependent in the original code. These were not carried
over to this codebase. Race conditions between calls to decrypt and
the periodic timer, led to incorrect reference count values.
CdmSession objects were then destructed while references to
them still existed. Segfaults occurred when they were referenced.

73c3007c24 Address offline playback with rollbacked time
Merge from http://go/wvgerrit/47640

Test: unit/integration tests

Bug: b/62058202

The usage table keeps track of license duration by using the current
system time. However, if a user were to rollback the time, they can
effectively continue offline playback indefinitely. This changes the way
we compute time by computing offsets by which the user rollbacked the
time and adding it to the current time. This change also includes a test
to verify protection against rollback for usage entries that is only run
when the user is root.

f0cd22d4f4 Address failures when provisioning methods differ
[ Merge of http://go/wvgerrit/46907 ]

The WV client supports root of trusts as keyboxes or OEM certificates.
Devices with keyboxes use provisioning 2.0 protocol to provision
while those with OEM certificates use 3.0. L3 provisioning failures
occur if the L1 and L3 root of trusts differ.

The provisioning method is now retrieved and cached when the
security level is known, when the session is opened.
Earlier it was retrieved and cached at initialization time and
always set to the value of L1 OEMCrypto (if present). This led
to provisioning failures.

A case of acquiring a lock while one was held in GetProvisioningId()
has also fixed.
