Here is the change log for this revision:
- ERRATA: AFSCAPABILITIESMAX is actually defined to be 196, not 192
- add section re: cache coherence to the tag enumeration RPC
- add section re: day-of-week usage following discussion with mmeffie
- s/AFSVOL_TLV_TAG_VOL_DAY_USE/AFSVOL_TLV_TAG_VOL_STAT_USE_TODAY/
following discussion with mmeffie
- add AFSVOL_TLV_TAG_VOL_STAT_USE_TODAY_DATE following discussion with
mmeffie
- add section re: definition of each tlv payload type
- add section re: definition of each tlv flag
- add note soliciting comments to afs3-stds list
- s/GCO Registrar/AFS Assigned Numbers Registrar/
- s/afsint/AFSVol/ so that we keep our options open with respect to
wider standardization of TLV semantics
- add AFSVOL_TLV_TYPE_UINT64_VEC payload type
- convert various tags from AFSVOL_TLV_TYPE_OPAQUE to
AFSVOL_TLV_TYPE_UINT64_VEC
- add AFSVOL_TLV_FLAG_QUALIFIER_NO_MATCH flag
- write AFSVol TLV Payloads registry definition
- write AFSVol TLV Tags registry definition
- add registry for AFSVol_TLV.tlv_flags
- add registry for AFSVol_stat_use_per_dow.stat_flags
- write AFSVol Vol State Expls registry definition
- write AFSVol Program Types registry definition
- add numeric value assignments for newly created registries
- add RFC section references to new allocations
- add reference to Simon's AFS-STDS charter
- add an appendix with sample XDR for AFSVol Capabilities
- add an appendix with sample XDR for AFSVol TLV
- various cosmetic improvements (e.g. adding vspace tags)
Moving forward, I propose making one change in -03. Namely, I want to
split type AFSVOL_TLV_TYPE_UINT64 up into a few types that embed some
limited semantic knowledge into the TLV layer. Specifically, I'm thinking
of splitting AFSVOL_TLV_TYPE_UINT64 into the following six types:
* AFSVOL_TLV_TYPE_UINT64 [generic unit-less type, as before]
* AFSVOL_TLV_TYPE_TIME_ABS [Simon's rpc refresh 100ns unit; absolute]
* AFSVOL_TLV_TYPE_TIME_REL [Simon's rpc refresh 100ns unit; relative]
* AFSVOL_TLV_TYPE_BLOCKS [storage in 1KiB units]
* AFSVOL_TLV_TYPE_VOLUME_ID
* AFSVOL_TLV_TYPE_PARTITION_ID
All six would be backed by afs_uint64 in the AFSVol_TLV_value union.
While this change isn't strictly necessary, it's relatively
straightforward to implement, and makes the resulting volume TLV data
considerably more self-describing.
As always, comments and feedback are invited.
Cheers,
-Tom
