/* |
|
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 |
|
since has inode num |
|
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 |
|
TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended |
|
T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL |
