1975 For better POSIX semantics from Linux client, (even better
1976 than the existing CIFS Unix Extensions) we need updated PDUs for:
1978 1) PosixCreateX - to set and return the mode, inode#, device info and
1979 perhaps add a CreateDevice - to create Pipes and other special .inodes
1980 Also note POSIX open flags
1981 2) Close - to return the last write time to do cache across close more safely
1982 3) FindFirst return unique inode number - what about resume key, two
1983 forms short (matches readdir) and full (enough info to cache inodes)
1986 And under consideration:
1987 5) FindClose2 (return nanosecond timestamp ??)
1988 6) Use nanosecond timestamps throughout all time fields if
1989 corresponding attribute flag is set
1990 7) sendfile - handle based copy
1994 what about fixing 64 bit alignment
1996 There are also various legacy SMB/CIFS requests used as is
1998 From existing Lanman and NTLM dialects:
1999 --------------------------------------
2001 SESSION_SETUP_ANDX (BB which?)
2002 TREE_CONNECT_ANDX (BB which wct?)
2003 TREE_DISCONNECT (BB add volume timestamp on response)
2005 DELETE (note delete open file behavior)
2009 LOCKING_AND_X (note posix lock semantics)
2010 RENAME (note rename across dirs and open file rename posix behaviors)
2011 NT_RENAME (for hardlinks) Is this good enough for all features?
2013 TRANSACTION2 (18 cases)
2014 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2015 (BB verify that never need to set allocation size)
2016 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
2018 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2019 setting/getting OS/2 EAs - FUTURE (BB can this handle
2020 setting Linux xattrs perfectly) - OPTIONAL
2021 dnotify - FUTURE, OPTIONAL
2022 quota - FUTURE, OPTIONAL
2024 Note that various requests implemented for NT interop such as
2025 NT_TRANSACT (IOCTL) QueryReparseInfo
2026 are unneeded to servers compliant with the CIFS POSIX extensions
2028 From CIFS Unix Extensions:
2029 -------------------------

2033 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields

2035 BB what about a) blksize/blkbits/blocks
2041 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2042 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
