b6e6379514 selftest: Use a unique(ish) OU for every run of getnc_unpriv
An intermittent problem I noticed with tests in the past is that the
setup can fail to create the base OU because it already exists.
I believe this is because the previous testenv DC has replicated out the
test object, but not its deletion at the point that the next testenv DC
starts running the test.

This only seemed to happen very occassionally (I haven't seen it
happen with getnc_unpriv yet, but I also haven't run it through the
autobuild yet).

Using same randomness in the test OU should help avoid this sort of
problem, and it matches what some other replication tests do.

37ed946c75 selftest: Update getnc_unpriv tests to pass against Samba
In general Windows seems to return BAD_DN rather than ACCESS_DENIED for
an unprivileged user. In the the long-term, it's unrealistic to think
that Samba and Windows will agree exactly on every error code returned.
So for the tests to be maintainable and pass against Windows and Samba,
they need to handle differences in expected errors. To get around this
problem, I've changed the expected_error to be a set, so that multiple
error codes (one for Microsoft, one for Samba) can be specified for each
test case. This approach also highlights the cases where Microsoft and
Samba currently differ.

2d0766a48b s4-drsuapi: Set getnc_state *after* we've checked request is valid
We were creating the getnc_state (and storing it on the connection)
before we had done some basic checks that the request was valid. If the
request was not valid and we returned early with an error, then the
partially-initialized getnc_state was left hanging on the connection.
The next request that got sent on the connection would try to use this,
rather than creating a new getnc_state from scratch.

The main side-effect of this was if you sent an invalid GetNCChanges
request twice, then it could be rejected the first time and accepted the
second time.

Note that although an invalid request was accepted, it would typically
not return any objects, so it would not actually leak any secure
information.

6158f1839f selftest: GetNCChanges can 'accept' a repeated bad request
In theory, if we send the exact same rejected request again, we should
get the same response back from the DC. However, we don't - the request
is accepted if we send it a second time.

This patch updates the repl_rodc test to demonstrate the problem (which
now causes the test to fail).

Note that although the bad GetNCChanges request is not rejected outright,
the response that gets sent back is empty - it has no objects in it, so
it's not an actual security hole. It is annoying problem for writing
self-tests though.

122c8e1fa2 selftest: Extend further getnc_unpriv tests to pass against windows 2012R2
An important change in this patch is changing the ACE type from
 A (Allow)
to
 AO (Object Allow)

as that will then respect the supplied GUID, which we also make use
the constant from the security.idl.

This reworks the tests to check replication with users with the
following rights:
- only GET_CHANGES
- only GET_ALL_CHANGES
- both GET_CHANGES and GET_ALL_CHANGES
- no rights

We basically want to test various different GetNCChanges requests
against each type of user rights, and the only difference is the
error/success value we get back. I've structured the tests this way, so
that we have 4 test_repl_xyz_userpriv() functions (to cover each of the
above user rights cases), and each test sends the same series of
GetNCChanges requests of varying validity.

Currently all these tests fail against Samba because Samba sends
different error codes to Windows.

0bb4d28272 getncchanges.py: Add test for GET_ANC and linked attributes
Add a basic test that when we use GET_ANC and the parents have linked
attributes, then we receive all the expected links and all the expected
objects by the end of the test.

This extends the test code to track what linked attributes get received
and check whether they match what's present on the DC.

Also made some minor cleanups to store the received objects/links each
time we successfully receive a GETNCChanges response (this saves the
test case having to repeat this code every time).

Note that although this test involves linked attributes, it shouldn't
exercise the GET_TGT case at all.

9f0ae6e44d getncchanges.py: Add GET_ANC replication test case
This test:
- creates blocks of parent/child objects
- modifies the parents, so the child gets received first in the
  replication (which means the client has to use GET_ANC)
- checks that we always receive the parent before the child (if not, it
  either retries with GET_ANC, or asserts if GET_ANC is already set)
- modifies the parent objects to change their USN while the
  replication is in progress
- checks that all expected objects are received by the end of the
  test

I've added a repl_get_next() function to help simulate a client's
behaviour - if it encounters an object it doesn't know the parent of,
then it retries with GET_ANC.

Also added some debug to drs_base.py that developers can turn on to make
it easier to see what objects we're actually receiving in the
responses.

4cfc296885 getncchanges.py: Add a new test for replication
This adds a new test to check that if objects are modified during a

Note that when this scenario occurs, samba returns the objects in a
different order to Windows. This test doesn't care what order the
replicated objects get returned in, so long as they all have been
received by the end of the test.

As part of this, I've refactored _check_replication() in drs_base.py so
it can be reused in new tests. In these cases, the objects are split up
over multiple different chunks. So asserting that the objects are returned
in a specific order makes it difficult to run the same test on both Samba

fae5df891c replmd: Try to add forward-link for unknown cross-partition links
Previously Samba would just drop cross-partition links where the link
target object is unknown. Instead, what we want to do is try to add the
forward link for the GUID specified. We can't add the backlink because
we don't know the target, however, dbcheck should be able to fix any
missing backlinks.

The new behaviour should now mean dbcheck will detect the problem and be
able to fix it. It's still not ideal, but it's better than dropping the
link completely.

I've updated the log so that it has higher severity and tells the user
what they need to do to fix it.

These changes now mean that the selftests now detect an error - instead
of completely dropping the serverReference, we now have a missing
backlink. I've updated the selftests to fix up any missing
serverReference backlinks before running dbcheck.

89cf5c3f76 replmd: Don't fail cycle if we get link for deleted object with GET_TGT
We are going to end up supporting 2 different server schemes:
A. the old/default behaviour of sending all the linked attributes last,
   at the end of the replication cycle.
B. the new/Microsoft way of sending the linked attributes interleaved
   with the source/target objects.

Normally if we're talking to a server using the old scheme-A, we won't
ever use the GET_TGT flag. However, there are a couple of cases where
it can happen:
- A link to a new object was added during the replication cycle.
- An object was deleted while the replication was in progress (and
the linked attribute got queued before the object was deleted).

Talking to an Samba DC running the old scheme will just cause it to
start the replication cycle from scratch again, which is fairly
harmless. However, there is a chance that the same thing can happen
again, in which case the replication cycle will fail (because GET_TGT
was already set).

Even if we're using the new scheme (B), we could still potentially hit
this case, as we can still queue up linked attributes between requests
(group memberships can be larger than what can fit into a single
replication chunk).

If GET_TGT is set in the GetNcChanges request, then the local copy of
the target object should always be up-to-date when we process the linked
attribute. So if we still think the target object is deleted/recycled at
this point, then it's safe to ignore the linked attribute (because we
know our local copy is up-to-date). This logic matches the MS spec logic
in ProcessLinkValue().

Not failing the replication cycle may be beneficial if we're trying to
do a full-sync of a large database. Otherwise it might be time-consuming
and frustrating to repeat the sync unnecessarily.

ab12aed7e1 replmd: Avoid dropping links if link target is deleted
The server-side can potentially send the linked attribute before the
target-object. This happens on Microsoft, and will happen on Samba once
server-side GET_TGT support is added. In these cases there is a hole
where the Samba client can silently drop the linked attribute.

If the old copy of the target object was deleted/recycled, then the
client can receive the new linked attribute before it realizes the target
has now been reincarnated. It silently ignores the linked attribute,
thinking its receiving out of date information, when really it's the
client's copy of the target object that's out of date.

In this case we want to retry with the GET_TGT flag set, which will
force the updated version of the target object to be sent along with the
linked attribute. This deleted/recycled target case is the main reason
that Windows added the GET_TGT flag.

If the server sends all the links at the end, instead of along with the
source object, then this case can still be hit. If so, it will cause the
server to restart the replication from the beginning again. This is
probably preferential to silently dropping links.

18ea167ade replmd: Move where we store linked attributes
There was a bug in my previous patch where the code would verify
*all* links in the list, rather than just the ones that are new. And it
would do this for every replication chunk it received, regardless of
whether there were actually any links in that chunk.

The problem is by the time we want to verify the attributes, we don't
actually know which attributes are new. We can fix this by moving where
we store the linked attributes from the start of processing the
replication chunk to the end of processing the chunk. We can then verify
the new linked attributes at the same time we store them.

Longer-term we may want to try to apply the linked attribute at this
point. This would save looking up the source/target objects twice, but
it makes things a bit more complicated (attributes will usually apply at
this point *most* of the time, but not *all* the time).

Windows replication can send the linked attribute before it sends the
source object. The MS-DRSR spec says that in this case the client should
resend the GetNCChanges request with the GET_ANC flag set. In my testing
this resolves the problem - Windows will include the source object for the
linked attribute in the same replication chunk.

This problem doesn't happen with Samba-to-Samba replication, because the
source object for the linked attribute is guaranteed to have already been
sent.

highly inefficient. Because Samba keeps the GET_TGT flag set throughout
the replication cycle, it will basically receive a repeated object from
Windows for every single linked attribute that it receives.

I believe Windows behaviour only expects the client to set the GET_TGT
flag when it actually needs to (i.e. when it receives a target object it
doesn't know about), rather than throughout the replication cycle.
However, this approach won't work with Samba-to-Samba replication,
because when the server receives the GET_TGT flag it restarts the
replication cycle from scratch. So if we only set the GET_TGT flag when
the client encountered an unknown target then Samba-to-Samba could
potentially get into an endless replication loop.

67617d4700 drs: Check target object is known after applying objects
Currently we only check that the target object is known at the end of
the transaction (i.e. the .prepare_commit hook). It's too late at this
point to resend the request with GET_TGT. Move this processing earlier
on, after we've applied all the objects (i.e. off the .extended hook).

In reality, we need to perform the checks at both points. I've
split the common code that gets the source/target details out of the
la_entry into a helper function. It's not the greatest function ever,
but seemed to make more sense than duplicating the code.

f69596cd21 drs: Fail replication transaction instead of dropping links
If the DRS client received a linked attribute that it couldn't resolve
the target for, then it would just ignore that link and keep going. That
link would then be lost forever (although a full-sync would resolve
this). Instead of silently ignoring the link, fail the transaction.

This *can* happen on Samba, but it is unusual. The target object and
linked-attribute would need to be added while a replication is still in
progress. It can also happen fairly easily when talking to a Windows DC.

There are two import exceptions to this:

1). Linked attributes that span partitions. We can never guarantee that
we will have received the target object, because it may be in a partition
we haven't replicated yet. Samba doesn't have a great way of handling
this currently, but we shouldn't fail the replication (because that breaks
basic join tests). Just skip that linked attribute and hope that a
subsequent full-sync will fix it.
(I queried Microsoft and they said resolving cross-partition linked
attributes is a implementation-specific problem to solve. GET_TGT won't
resolve it)

2). When the replication involves a subset of objects, e.g.
critical-only. In these cases, we don't increase the highwater-mark, so
it is probably not such a dire problem if we don't add the link. In the
case of critical-only, we will do a subsequent full sync which will then
add the links.

04ce638a1f replmd: Split checking link attr target into new function
We want to re-use this code to check that the linked attribute's target
object exists *before* we try to commit the transaction. This will allow
us to re-request the block with the GET_TGT flag set.

This splits checking the target object exists into a separate function.

Minor changes of note:
- the 'parent' argument was passed to replmd_process_linked_attribute()
  as NULL, so I've just replaced where it was used in the refactored code
  with NULL.
- I've tweaked the "Failed to find GUID" error message slightly to display
  the attribute ID rather than the attribute name (saves repeating
  lookups and/or passing extra arguments).
- Tweaked the replmd_deletion_state() logic - it only made sense to call
  it in the code block where we actually found the target
