thi ensures we are using the header corresponding to the version of
ldb we're linking against. Otherwise we could use the system ldb for
link and the in-tree one for include

This is needed to fix a Tru64 "cc" warning regarding "enum drepl_role_master".

when a replication fails, we should add the failure to repsFrom
when a notify fails, we need to save it to repsTo
this ensures showrepl always shows the latest status
|
|
when there was a continuous sequence of notify ops, we could leave the
replication ops starving. This ensures we run whichever was queued
first

We need a separate source dsa list for RODCs, as they are not in the
repsFrom for our partitions, but are in the repsTo. This adds a new
'notifies' list, which contains all the source dsas for the DCs that
we should send notifies to, but which we don't replicate from

Otherwise we'll requeue the same notify events on and on.

We can reuse this operations, while they're not yet started.

this is required when talking to RODCs (for notify calls), and is good
practice for all DCs

It's useless to get messages like this every few seconds:
dreplsrv_notify: Failed to send DsReplicaSync to
edbf4745-2966-49a7-8653-99200f1c9430._msdcs.samba2003.example.com for
CN=Configuration,DC=samba2003,DC=example,DC=com -
NT_STATUS_OBJECT_NAME_NOT_FOUND : WERR_BADFILE
We have a non bug regarding non-linked DN attributes
and changes of the target DN.

The 0xc0002104/WERR_DS_DRA_NO_REPLICA seems to be spurious, and can be
avoided by setting DRSUAPI_DRS_SYNC_ALL in the DsReplicaSync request.
We need to investigate this further, and find out from MS why this is
sometimes being sent, even when the target DC has the right repsFrom
entries
|
|
we rely on the highestUSN counters instead. W2K8 does not resend
DsUpdateRefs each time, and the WSPP docs do not indicate that repsTo
should be deleted

I changed also some "uint32_t" to "unsigned" since the LDB interface doesn't
specify the bitlength of the unsigned type.

when necessary
If an urgent replication is necessary, so the uSNUrgent stored is equal to the
uSNHighest stored, then when sending the DS_ReplicaSync message it sets the
DRSUAPI_DRS_SYNC_URGENT bit on DRS_OPTIONS.

WSPP uses a single set of flags for all these DRS operations.
|
|
When a object or attribute is created/updated/deleted, according
to [MS-ADTS] 3.1.1.5.1.6, it stores the uSNUrgent on @REPLCHANGED
for the partitions that it belongs.

This make the whole async dreplsrv_op_notify_send/recv()
readable.

When one of our core tasks fails to initialise it can now ask for the
server as a whole to die, rather than limping along in a degraded
state.
|
|
Windows does not seem to be always setting up repsTo using
DsUpdateRefs(). For now we will fall back to using repsFrom if repsTo
is empty. This is almost certainly incorrect, but it does get
notification based replication working with both w2k3 and w2k8.
|
|
The dreplsrv_notify code checks the partition uSN values every N
seconds, and if one has changed then it sends a DsReplicaSync to all
the replication partners listed in the repsTo attribute for the
partition.
