Ensure we don't use any of the create_options for Samba private
use. Add a new parameter to the VFS_CREATE call (private_flags)
which is only used internally. Renumber NTCREATEX_OPTIONS_PRIVATE_DENY_DOS
and NTCREATEX_OPTIONS_PRIVATE_DENY_FCB to match the S4 code).
Rev. the VFS interface to version 28.

Final fix for the vfs_acl_xattr and vfs_acl_tdb code.
Ensure we can delete a file even if the underlying POSIX
permissions don't allow it, if the Windows permissions do.
Jeremy.
When returning an underlying ACL on a directory, normally on a
POSIX system it has no inheritable entries, which breaks the
Windows ACL when a user does a get/set of a Windows ACL on a
POSIX directory with no existing stored Windows ACL from
the Windows ACL editor. What happens is any new entry added
by the user gets set inheritable, but none of the others
entries are (as returned by default). So any new files then
only inherit the single new ACE entry (the one marked inheritable
by the ACL editor).
Fix this by faking up a default 3 element inheritable ACL that
represents what a user creating a POSIX file or directory will
get by default from the smbd code.

Volker was right (dammit :-). It's much easier to catch
this case in the create_file() vfs call instead of trying
to do everything inside open() and mkdir(). Hook all these
functions to gain the desired effect.
Jeremy.
right. The previous bugs were due to the fact that get_nt_acl_internal()
could return an NTSTATUS error if there was no stored ACL blob, but
otherwise would return the underlying ACL from the filysystem. Fix
this so it always returns a valid acl if it can, and if it does not
its an error to be reported back to the client. This then changes
the inherit acl code. Previously we were trying to match Windows
by setting a minimal ACL on a new file that didn't inherit anything
from a parent directory. This is silly - the returned ACL wouldn't
match the underlying UNIX permissions. The current code will correctly
inherit from a parent if a parent has any inheritable ACE entries
that apply to the new object, but will return a mapping from the
underlying UNIX permissions if the parent has no inheritable entries.
This makes much more sense for new files/directories.

reads off the underlying filesystem. Ensure that vfs_acl_tdb.c
returns NT_STATUS_NOT_FOUND, not NT_STATUS_OBJECT_NAME_NOT_FOUND
when it can't find a blob matching the file.
Jeremy.
Fix ACL modules to test for permissions on open/mkdir/opendir.
Ensure that underlying ACLs are returned for directories/files with
no Windows xattr or tdb acls stored.
Jeremy.
into acl_tdb and acl_xattr. Duplicates the code size, but keeps
the code in common so I don't have to do bug fixes in two places
(which is what I really cared about).
Jeremy.
