2305 For better POSIX semantics from Linux client, (even better
2306 than the existing CIFS Unix Extensions) we need updated PDUs for:
2308 1) PosixCreateX - to set and return the mode, inode#, device info and
2309 perhaps add a CreateDevice - to create Pipes and other special .inodes
2310 Also note POSIX open flags
2311 2) Close - to return the last write time to do cache across close
2313 3) FindFirst return unique inode number - what about resume key, two
2314 forms short (matches readdir) and full (enough info to cache inodes)
2317 And under consideration:
2318 5) FindClose2 (return nanosecond timestamp ??)
2319 6) Use nanosecond timestamps throughout all time fields if
2320 corresponding attribute flag is set
2321 7) sendfile - handle based copy
2325 what about fixing 64 bit alignment
2327 There are also various legacy SMB/CIFS requests used as is
2329 From existing Lanman and NTLM dialects:
2330 --------------------------------------
2332 SESSION_SETUP_ANDX (BB which?)
2333 TREE_CONNECT_ANDX (BB which wct?)
2334 TREE_DISCONNECT (BB add volume timestamp on response)
2336 DELETE (note delete open file behavior)
2340 LOCKING_AND_X (note posix lock semantics)
2341 RENAME (note rename across dirs and open file rename posix behaviors)
2342 NT_RENAME (for hardlinks) Is this good enough for all features?
2344 TRANSACTION2 (18 cases)
2345 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2346 (BB verify that never need to set allocation size)
2347 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via
2350 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2351 setting/getting OS/2 EAs - FUTURE (BB can this handle
2352 setting Linux xattrs perfectly) - OPTIONAL
2353 dnotify - FUTURE, OPTIONAL
2354 quota - FUTURE, OPTIONAL
2356 Note that various requests implemented for NT interop such as
2357 NT_TRANSACT (IOCTL) QueryReparseInfo
2358 are unneeded to servers compliant with the CIFS POSIX extensions
2360 From CIFS Unix Extensions:
2361 -------------------------
2362 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2363 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2364 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2365 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2366 Actually need QUERY_FILE_UNIX_INFO since has inode num
2367 BB what about a) blksize/blkbits/blocks
2373 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2374 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2375 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
