[cifs-protocol] MS-DNSP errata on timestamp descriptions - TrackingID#2106010040000420

Hi Douglas,

We have updated [MS-DNSP] for the next release of the document:

3.1.1.1.1 DNS Server Integer Properties
DsTombstoneInterval:
Every day at 2:00 AM local time the DNS server MUST conduct a search of all zones stored in the directory server for nodes which have the dnsTombstoned attribute set to TRUE and an EntombedTime (section 2.2.2.2.4.23) value greater than DsTombstoneInterval seconds in the past (convert seconds to 100-nanosecond intervals for comparison). Any such nodes MUST be permanently deleted from the directory server <127>

3.1.4.5 R_DnssrvUpdateRecord (Opnum 4)
When processing this call, the server MUST do the following:
§	If pszZoneName points to a primary zone, attempt to perform addition/deletion/update of the record. If the operation is successful, increment the zone serial number using serial number arithmetic [RFC1982]. If the zone is directory server-integrated and the update causes new or modified records to be committed to the directory, the new zone serial number MUST also be written to the Serial field of the dnsRecord attribute (section 2.3.2.2). If the last record at the node is being deleted and the zone is stored in the directory server or is directory server-integrated, the DNS server MUST set the node's dnsTombstoned attribute to TRUE and the node's dnsRecord attribute to contain a DNS_RPC_RECORD_TS record (section 2.2.2.2.4.23) with an EntombedTime value equal to the current time expressed as the number of 100-nanosecond intervals since 12:00 A.M. January 1, 1601 Coordinated Universal Time (UTC).

Hi Douglas,

I have been able to confirm that EntombedTime is actually (and always) in 100-nanosecond increments. Also, "Time Zone Secured" is tracked in full seconds as documented. 

The comparison in section 3.1.1.1.1 should perhaps read: "...and an EntombedTime (section 2.2.2.2.4.23) value >>>indicating a time<<< greater than DsTombstoneInterval seconds in the past."

I will file a request to update the document and follow up on it. Let me know if you have any further questions on EntombedTime.

hi Dochelp,

In a number of places [MS-DNSP] mentions timestamps in to form of "the number of seconds since 12:00 A.M. January 1, 1601". At least some of these should really speak of the "number of 100-nanosecond intervals" that we are used to dealing with.

In 3.1.4.5, in the paragraph starting "If pszZoneName points to a primary zone", EntombedTime is described as a number of seconds, contrary to descriptions elsewhere (2.2.2.2.4.23).

Same thing in 3.1.1.1.1, under "DsTombstoneInterval", EntombedTime is compared with a number of seconds.

Also in sections 3.1.1 and 3.1.1.2.1 "Time Zone Secured" is described as the number of seconds since 1601. I don't know if that is correct or not.


This is not really a question, unless EntombedTime is really sometimes in seconds and sometimes in 10-millionths of seconds, in which case I will have lots of questions.

Douglas
