torture test
This third patch cleans up by removing all of the code that is made
obsolete by the first patch. It should cause no functional changes.

torture test
smbtorture4's BASE-DELETE:deltest17 was failing against win2k8,
win2k3, and winXPsp2 but passing against samba.
deltest17 does the following:
1. open file -> file is created
2. closes file
3. open file with DOC -> fnum1
4. check that DOC is not reported as being set from fnum1
5. opens file again Read Only -> fnum2
6. check that DOC is not reported as being set from either file handle
7. close fnum1 (the file handle that requested DOC to be set)
8. check if DOC is reported as being set from fnum2
* This is where windows and samba begin to diverge. Windows
reports that the DOC bit is set, while samba reports that it is not set.
9. close fnum2 (the last remaining open handle for the file)
10.See if the file has been deleted.
* On samba the file still exists. On windows the file was deleted.
The way open_file_ntcreate is written now, if an open has the DOC bit
set on the wire, DOC (fsp->initial_delete_on_close) is not set unless:
a. the open creates the file, or b. there is an open file handle with
a share_entry in the struct lck that has the
SHARE_MODE_ALLOW_INITIAL_DELETE_ON_CLOSE bit set (let's call it
SM_AIDOC).
My understanding of SM_AIDOC is that it was added to differentiate
between DOC being set on an open that creates a file vs an open that
opens an existing. As described in step 8/10 above, it appears that
windows does not make this differentiation.
To resolve this issue there are three patches. This first patch is a
simple proof of concept change that is sufficient to fix the bug. It
removes the differentiation in open_file_ntcreate, and updates
deltest17 to allow it to pass against win2k3/xp. This makes
open_file_ntcreate more closely match the semantics in open_directory
and rename_internals_fsp. This change also does not break any other
tests in BASE-DELETE or "make test". Specifically test deltest20b
which verifies the CIFSFS rename DOC semantics still passes :).

This allows vfs modules that implement SMB_VFS_CREATE_FILE to access
some of the useful utility functions.

This replaces the is_dos_path bool with a more future-proof argument.
The next step is to plumb INTERNAL_OPEN_ONLY through this flag instead
of overridding the oplock_request.
|
|
Also removed open_file_ntcreate/open_file from proto.h so they can no
longer be called directly.

Now unix paths can be differentiated from windows paths so the
underlying create_file implementations can convert paths correctly.

Modify all callers of create_file to go through SMB_VFS_CREATE_FILE

caused us to
run into kernel oplocks on an open for a stream inside a file with stream_xattr module. On
opening the base_fsp we must break existing oplocks." as it broke make test.

that generic bits are not returned when querying an ACL set using them (ie. only
the specific bits are stored on disk).

We don't need to deny a DELETE open on a readonly file (I'm also adding a s4
torture test for this), the set_file_disposition call will return
NT_STATUS_CANNOT_DELETE if the delete-on-close bit is set
on a readonly file (and we already do this).

Some of the bits generate INVALID_PARAMETER and some bits
are ignored when they come from a client, that's why we need
to use bits from the ignored range for our internal usage.

current_user_info was "only" used in a debug msg, and current_user.ut.uid is
also available via conn->server_info

The current vuid is not only available there, it is also in the current

This hides the pending close fds from the outside. Call order
of SMB_VFS_CLOSE is reversed. Originally, it was:
fd_close -> fd_close_posix -> SMB_VFS_CLOSE -> close
And now it is:
fd_close -> SMB_VFS_CLOSE -> fd_close_posix -> close
This is in preparation of removing the fd parameter
from the SMB_VFS_CLOSE function. But it is also the right
place for the pending close calls anyways.

This is needed to implement the strange write time update
logic later. We need to store 2 time timestamps to
distinguish between the time the file system had before
the first client opened the file and a forced timestamp update.

Found by a "set but never used" warning. Thanks to talloc_tos() this was not
really a bug, but this way the code becomes much clearer.
