- For better POSIX semantics from Linux client, (even better
- than the existing CIFS Unix Extensions) we need updated PDUs for:
-
- 1) PosixCreateX - to set and return the mode, inode#, device info and
- perhaps add a CreateDevice - to create Pipes and other special .inodes
- Also note POSIX open flags
- 2) Close - to return the last write time to do cache across close
- more safely
- 3) FindFirst return unique inode number - what about resume key, two
- forms short (matches readdir) and full (enough info to cache inodes)
- 4) Mkdir - set mode
-
- And under consideration:
- 5) FindClose2 (return nanosecond timestamp ??)
- 6) Use nanosecond timestamps throughout all time fields if
- corresponding attribute flag is set
- 7) sendfile - handle based copy
-
- what about fixing 64 bit alignment
-
- There are also various legacy SMB/CIFS requests used as is
-
- From existing Lanman and NTLM dialects:
- --------------------------------------
- NEGOTIATE
- SESSION_SETUP_ANDX (BB which?)
- TREE_CONNECT_ANDX (BB which wct?)
- TREE_DISCONNECT (BB add volume timestamp on response)
- LOGOFF_ANDX
- DELETE (note delete open file behavior)
- DELETE_DIRECTORY
- READ_AND_X
- WRITE_AND_X
- LOCKING_AND_X (note posix lock semantics)
- RENAME (note rename across dirs and open file rename posix behaviors)
- NT_RENAME (for hardlinks) Is this good enough for all features?
- FIND_CLOSE2
- TRANSACTION2 (18 cases)
- SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
- (BB verify that never need to set allocation size)
- SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
- Unix ext?)
-
- COPY (note support for copy across directories) - FUTURE, OPTIONAL
- setting/getting OS/2 EAs - FUTURE (BB can this handle
- setting Linux xattrs perfectly) - OPTIONAL
- dnotify - FUTURE, OPTIONAL
- quota - FUTURE, OPTIONAL
-
- Note that various requests implemented for NT interop such as
- NT_TRANSACT (IOCTL) QueryReparseInfo
- are unneeded to servers compliant with the CIFS POSIX extensions
-
- From CIFS Unix Extensions:
- -------------------------
- T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
- T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
- T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
- T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) BB check for missing
- inode fields
- Actually a need QUERY_FILE_UNIX_INFO

- BB what about a) blksize/blkbits/blocks
- b) i_version
- c) i_rdev
- d) notify mask?
- e) generation
- f) size_seqcount
- T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX

+ 2) Close - to return the last write time to do cache across close

+ 3) FindFirst return unique inode number - what about resume key, two

+ 4) Mkdir - set mode

+ SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
+ (BB verify that never need to set allocation size)
