2223 For better POSIX semantics from Linux client, (even better
2224 than the existing CIFS Unix Extensions) we need updated PDUs for:
2226 1) PosixCreateX - to set and return the mode, inode#, device info and
2227 perhaps add a CreateDevice - to create Pipes and other special .inodes
2228 Also note POSIX open flags
2229 2) Close - to return the last write time to do cache across close more safely
2230 3) FindFirst return unique inode number - what about resume key, two
2231 forms short (matches readdir) and full (enough info to cache inodes)
2234 And under consideration:
2235 5) FindClose2 (return nanosecond timestamp ??)
2236 6) Use nanosecond timestamps throughout all time fields if
2237 corresponding attribute flag is set
2238 7) sendfile - handle based copy
2242 what about fixing 64 bit alignment
2244 There are also various legacy SMB/CIFS requests used as is
2246 From existing Lanman and NTLM dialects:
2247 --------------------------------------
2249 SESSION_SETUP_ANDX (BB which?)
2250 TREE_CONNECT_ANDX (BB which wct?)
2251 TREE_DISCONNECT (BB add volume timestamp on response)
2253 DELETE (note delete open file behavior)
2257 LOCKING_AND_X (note posix lock semantics)
2258 RENAME (note rename across dirs and open file rename posix behaviors)
2259 NT_RENAME (for hardlinks) Is this good enough for all features?
2261 TRANSACTION2 (18 cases)
2262 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
2263 (BB verify that never need to set allocation size)
2264 SMB_SET_FILE_BASIC_INFO2 (setting times - BB can it be done via Unix ext?)
2266 COPY (note support for copy across directories) - FUTURE, OPTIONAL
2267 setting/getting OS/2 EAs - FUTURE (BB can this handle
2268 setting Linux xattrs perfectly) - OPTIONAL
2269 dnotify - FUTURE, OPTIONAL
2270 quota - FUTURE, OPTIONAL
2272 Note that various requests implemented for NT interop such as
2273 NT_TRANSACT (IOCTL) QueryReparseInfo
2274 are unneeded to servers compliant with the CIFS POSIX extensions
2276 From CIFS Unix Extensions:
2277 -------------------------
2278 T2 SET_PATH_INFO (SMB_SET_FILE_UNIX_LINK) for symlinks
2279 T2 SET_PATH_INFO (SMB_SET_FILE_BASIC_INFO2)
2280 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_LINK)
2281 T2 QUERY_PATH_INFO (SMB_QUERY_FILE_UNIX_BASIC) - BB check for missing inode fields
2282 Actually need QUERY_FILE_UNIX_INFO since has inode num
2283 BB what about a) blksize/blkbits/blocks
2289 T2 FIND_FIRST/FIND_NEXT FIND_FILE_UNIX
2290 TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
2291 T2_QFS_INFO QueryDevice/AttributeInfo - OPTIONAL
