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 :
- - - - - - - - - - - - - - - - - - - - - - - - -
