Project/Component Working Name: Correction in nbmand behavior 1.2. Name of Document Author/Supplier: Author: Afshin Salek 1.3 Date of This Document: 16 September, 2008 4. Technical Description This fast-track proposes a change to the functionality described in PSARC 2000/007 "Locking and File Sharing Support" due to the incorrect assertion that share reservations and byte range locks be checked against each other when the nbmand mount option is set. This behavior is not compliant with CIFS semantics and causes CIFS protocol errors, which negatively impact the functionality offered by the CIFS Service (PSARC 2006/715). Note that PSARC 2000/007 was introduced specifically in support of CIFS. Share reservations and byte range locks are not related. Share reservations are only checked when a file is opened, deleted or renamed, and are not affected by locks on existing open instances of the file. Byte range locks can be requested after a file has been opened successfully but existing share reservations on the open file do not affect whether byte range lock requests are granted or denied. Byte range locks are only checked against existing locks on the file. This fast track proposes that the share reservation and range lock cross-checking be removed. This will only affect system behavior when the nbmand option is set. There is no change in system behavior when nbmand option is not set, as there is no cross-check between share reservations and range locks. The change proposed by this fast track does not affect the share reservation check algorithm or the byte range lock check algorithm. 6. Resources and Schedule 6.4.
