b77f241b28 fix snapshot content display with hide unreadable
With the hide unreadable option set, snapshots are be displayed
as empty with shadow_copy2 and a NFSv4 ACL module.

To prevent multiple conversions of the paths when the acl call
does a VFS_STAT (as the nfs4acl code does), a check was added
to convert_shadow2_name() so it will not touch paths any more
that look like they have already been converted.

94a139afe5 shadow_copy2: The system getrealfilename() can't deal with a 0-length fname
This fixes viewing the content of snapshots in the share root directory. We
have to treat the filename that *just* consists of "@GMT-YYYY.MM.DD-HH.MM.SS"
like the share root, which is the current working directory.

e129384d7c s3: Plumb smb_filename through SMB_VFS_STAT and SMB_VFS_LSTAT
This patch introduces two new temporary helper functions
vfs_stat_smb_fname and vfs_lstat_smb_fname.  They basically allowed me
to call the new smb_filename version of stat, while avoiding plumbing
it through callers that are still too inconvenient.  As the conversion
moves along, I will be able to remove callers of this, with the goal
being to remove all callers.

There was also a bug in create_synthetic_smb_fname_split (also a
temporary utility function) that caused it to incorrectly handle
filenames with ':'s in them when in posix mode.  This is now fixed.

4e3656b8d1 s3: Change SMB_VFS_OPEN to take an smb_filename struct
This was a little messy because of all of the vfs modules I had to
touch.  Most of them were pretty straight forward, but the streams
modules required a little attention to handle smb_filename.  Since the
use of smb_filename enables the vfs modules to access the raw,
over-the-wire stream, a little bit of the handling that was being done
by split_ntfs_stream_name has now been shifted into the individual
stream modules.  It may be a little more code, but overall it gives
more flexibility to the streams modules, while also allowing correct
stream handling.

49ca690b4b Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STAT
This patch introduces

struct stat_ex {
        dev_t           st_ex_dev;
        ino_t           st_ex_ino;
        mode_t          st_ex_mode;
        nlink_t         st_ex_nlink;
        uid_t           st_ex_uid;
        gid_t           st_ex_gid;
        dev_t           st_ex_rdev;
        off_t           st_ex_size;
        struct timespec st_ex_atime;
        struct timespec st_ex_mtime;
        struct timespec st_ex_ctime;
        struct timespec st_ex_btime; /* birthtime */
        blksize_t       st_ex_blksize;
        blkcnt_t        st_ex_blocks;
};
typedef struct stat_ex SMB_STRUCT_STAT;

It is really large because due to the friendly libc headers playing macro
tricks with fields like st_ino, so I renamed them to st_ex_xxx.

Why this change? To support birthtime, we already have quite a few #ifdef's at
places where it does not really belong. With a stat struct that we control, we
can consolidate the nanosecond timestamps and the birthtime deep in the VFS
stat calls.

At this moment it is triggered by a request to support the birthtime field for
GPFS. GPFS does not extend the system level struct stat, but instead has a
separate call that gets us the additional information beyond posix. Without
being able to do that within the VFS stat calls, that support would have to be
scattered around the main smbd code.

It will very likely break all the onefs modules, but I think the changes will
be reasonably easy to do.

c33291d49f Fix annoying debug messages when no snapshots are used
Not being able to open the shadow copy directory is the same as having no
shadow copy support at all. The VFS module should in this case not log with
debug level 0 and set ENOSYS to indicate "no shadow copies used" to the higher
levels.

af0e199b31 Add an optional SMB_STRUCT_SMB parameter to VFS_OP_READDIR
* this allows VFS implementations that prefetch stat information on
  readdir to return it through one VFS call
* backwards compatibility is maintained by passing in NULL
* if the system readdir doesn't return stat info, the stat struct is
  set to invalid

48b0016cff Extend NTIMES to allow setting create_time
1) Add in smb_file_time struct to clarify code and make room for createtime.
2) Get and set create time from SMB messages.
3) Fixup existing VFS modules + examples Some OS'es allow for the
setting of the birthtime through kernel interfaces. This value is
generically used for Windows createtime, but is not settable in the
code today.

00b2cdf75e Yay ! Remove a VFS entry. Removed the set_nt_acl() call,
this can only be done via fset_nt_acl() using an open
file/directory handle. I'd like to do the same with
get_nt_acl() but am concerned about efficiency
problems with "hide unreadable/hide unwritable" when
doing a directory listing (this would mean opening
every file in the dir on list).
Moving closer to rationalizing the ACL model and
maybe moving the POSIX calls into a posix_acl VFS
module rather than having them as first class citizens
of the VFS.
Jeremy.

d52b66daac Merge a variant of Shadow Copy module for exposing snapshots to windows clients as shadow copies from Samba 3.0 CTDB
This is a 2nd implemetation of a shadow copy module for exposing
snapshots to windows clients as shadow copies. This version has the
following features:

     1) you don't need to populate your shares with symlinks to the
     snapshots. This can be very important when you have thousands of
     shares, or use [homes]

     2) the inode number of the files is altered so it is different
     from the original. This allows the 'restore' button to work
     without a sharing violation
