cifs: add new cifs_iget function and convert unix codepath to use it In order to unify some codepaths, introduce a common cifs_fattr struct for storing inode attributes. The different codepaths (unix, legacy, normal, etc...) can fill out this struct with inode info. It can then be passed as an arg to a common set of routines to get and update inodes. Add a new cifs_iget function that uses iget5_locked to identify inodes. This will compare inodes based on the uniqueid value in a cifs_fattr struct. Rather than filling out an already-created inode, have cifs_get_inode_info_unix instead fill out cifs_fattr and hand that off to cifs_iget. cifs_iget can then properly look for hardlinked inodes. On the readdir side, add a new cifs_readdir_lookup function that spawns populated dentries. Redefine FILE_UNIX_INFO so that it's basically a FILE_UNIX_BASIC_INFO that has a few fields wrapped around it. This allows us to more easily use the same function for filling out the fattr as the non-readdir codepath. With this, we should then have proper hardlink detection and can eventually get rid of some nasty CIFS-specific hacks for handing them.

/*

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
|

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

TRANS2_GET_DFS_REFERRAL - OPTIONAL but recommended
