77de8278e4 CVE-2018-16857 tests: Sanity-check password lockout works with default values
Sanity-check that when we use the default lockOutObservationWindow that
user lockout actually works.

The easiest way to do this is to reuse the _test_login_lockout()
test-case, but stop at the point where we wait for the lockout duration
to expire (because we don't want the test to wait 30 mins).

This highlights a problem currently where the default values don't work.

738418ea3e tests: Run backup tests against restoredc (SMBv1 disabled)
Running the backup tests against the restoredc highlights that the
backup online/rename commands don't work if SMBv1 is disabled. Note that
the offline commands still work because they don't rely on an SMB
connection to the server.

(Note that running the backup tests against the restoredc is probably a
good idea anyway, to prove that there's no limit to the number of times
you can restore a domain from backup, i.e. we support more than just a
one-off restore).

008449d99f netcmd: Flush replUpToDateVector when restoring offline backup
The replUpToDateVector could be incorrect after an offline backup was
restored. This means replication propagation dampening doesn't work
properly. In the worst case, a singleton DC would have no
replUpToDateVector at all, and so *all* objects created on that DC get
replicated every time a new DRS connection is established between 2 DCs.
This becomes a real problem if you used that singleton DC to create 100K
objects...

This patch flushes the replUpToDateVector when an offline backup gets
restored. We need to do this before we add in the new DC and remove the
old DCs.

Note that this is only a problem for offline backups. The online/rename
backups are received over DRS, and as part of the replication they
receive the latest replUpToDateVector from the DC being backed up.

ebfcf75e99 vfs_fruit: filter empty streams
First step in achieving macOS compliant behaviour wrt to empty streams:
- hide empty streams in streaminfo
- prevent opens of empty streams

This means that we may carry 0-byte sized streams in our streams
backend, but this shouldn't really hurt.

The previous attempt of deleting the streams when an SMB setinfo eof to
0 request came in, turned out be a road into desaster.

We could set delete-on-close on the stream, but that means we'd have to
check for it for every write on a stream and checking the
delete-on-close bits requires fetching the locking.tdb record, so this
is expensive and I'd like to avoid that overhead.

7b59cd74f9 dsdb encrypted_secrets: Allow "ldb:// and "mdb://" in file path
Correctly handle "ldb://" and "mdb://" schemes in the file path when
determining the path for the encrypted secrets key file.

When creating a new user and specifying the local file path of the
sam.ldb DB, it was possible to create an account that you could not
login with. The path for the key file was incorrectly calculated
for the "ldb://" and "mdb://" schemes, the scheme was not stripped from
the path and the subsequent open of the key file failed.

4092b369ae dsdb: Ensure that a DN (now) pointing at a deleted object counts for objectclass-based MUST
Add the 'reveal_internals' controls when performing objectclass-based
checks of mandatory attributes. This prevents the extended_dn DSDB
module from suppressing attributes that point to deleted (i.e.
non-existent/expunged) objects.

This ensures that, when modifying an object (and often not even
touching the mandatory attribute) that the fact that an attribute is a
DN, and the DN target is deleted, that the schema check will still pass.

Otherwise a fromServer pointing at a dead server can cause failures,
i.e. you can't modify the affected object at all, because the DSDB
thinks a mandatory attribute is missing.

dec3eda1f7 tests: Add corner-case test: fromServer points to dead server
The fromServer attribute is slightly unique, in that it's a DN (similar
to a one-way link), but it is also a mandatory attribute.

Currently, if fromServer gets a bad value (i.e. a dead server that has
been expunged), the DSDB rejects any attempts to modify the associated
nTDSConnection object (regardless of whether or not you're actually
changing the fromServer attribute).

This patch adds a test-case that demonstrates how the DB can get into
such a state.

31daab88e6 vfs_fruit: move check in ad_convert() to ad_convert_*() subfunctions
Currently the whole conversion is skipped if the FinderInfo entry in the
AppleDouble file is of the default size (ie not containing xattrs).

That also means we never converted FinderInfo from the AppleDouble file
to stream format. This change finally fixes this.

Note that this keeps failing with streams_depot, much like the existing
known-fail of "samba3.vfs.fruit streams_depot.OS X AppleDouble file
conversion". Fixing the conversion to work with vfs_streams_depot is a
task for another day.

4ef45e5334 smb2_server: set req->do_encryption = true earlier
The STATUS_SESSION_EXPIRED error was returned unencrypted,
if the request was encrypted.

If clients use SMB3 encryption and the kerberos authenticated session
expires, clients disconnect the connection instead of doing a reauthentication.

From https://blogs.msdn.microsoft.com/openspecification/2012/10/05/encryption-in-smb-3-0-a-protocol-perspective/

  The sender encrypts the message if any of the following conditions is
  satisfied:

    - If the sender is sending a response to an encrypted request.
    - If Session.EncryptData is TRUE and the request or response being
      sent is not NEGOTIATE.
    - If Session.EncryptData is FALSE, the request or response being sent
      is not NEGOTIATE or SESSION_SETUP or TREE_CONNECT, and
      <TreeConnect|Share>.EncryptData is TRUE.

[MS-SMB2] 3.3.4.1.4 Encrypting the Message

 If Connection.Dialect belongs to the SMB 3.x dialect family and
 Connection.ClientCapabilities includes the SMB2_GLOBAL_CAP_ENCRYPTION
 bit, the server MUST encrypt the message before sending, if any of the
 following conditions are satisfied:

 - If the message being sent is any response to a client request for which
   Request.IsEncrypted is TRUE.

 - If Session.EncryptData is TRUE and the response being sent is not
   SMB2_NEGOTIATE or SMB2 SESSION_SETUP.

 - If Session.EncryptData is FALSE, the response being sent is not
   SMB2_NEGOTIATE or SMB2 SESSION_SETUP or SMB2 TREE_CONNECT, and
   Share.EncryptData for the share associated with the TreeId in the SMB2
   header of the response is TRUE.

 The server MUST encrypt the message as specified in section 3.1.4.3,
 before sending it to the client.
