Fix incorrect interaction when all of
"inherit permissions = yes"
"inherit acls = yes"
"inherit owner = yes"
are set. Found by Björn Jacke. Thanks Björn !

If "inherit owner = yes", pass in the directory owner and group
owner as the target for CREATOR_OWNER and CREATOR_GROUP substitutions,
and also as the owner and primary group of the new security descriptor
being applied to the object.

Print child descriptor instead of parent.

Caused by premature optimisation storing the parent ACL on the
module handle instead of (correctly) on the file fsp. Previous
code wasn't reentrant safe. This is less optimal but doesn't
crash in the specific case :-).

this prevents a symbol duplication with the openssl library, which may
be linked in via a secondary library dependency

There is no reason for smbd with Windows ACLs to use chmod
or fchmod unless it's a file opened with UNIX extensions or
with posix pathnames.

These variables, of type struct auth_serversupplied_info were poorly
named when added into 2001, and in good consistant practice, this has
extended all over the codebase in the years since.
The structure is also not ideal for it's current purpose. Originally
intended to convey the results of the authentication modules, it
really describes all the essential attributes of a session. This
rename will reduce the volume of a future patch to replaced these with
a struct auth_session_info, with auth_serversupplied_info confined to
the lower levels of the auth subsystem, and then eliminated.
(The new structure will be the output of create_local_token(), and the
change in struct definition will ensure that this is always run, populating
local groups and privileges).

This will allow the auth_serversupplied_info struct to be migrated
to auth_session_info easier.

We were losing the incoming security descriptor revision number and
most importantly the "type" field as sent by the client. Ensure we
correctly store these in the xattr object.

Samba ACL module to ignore mapping to lower POSIX layer. With this
fix Samba 3.6.x now passes RAW-ACLs (with certain smb.conf parameters
set).

This will reduce the noise from merges of the rest of the
libcli/security code, without this commit changing what code
is actually used.
This includes (along with other security headers) dom_sid.h and
security_token.h

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.
Jeremy.
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.
Jeremy.
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.

Fix ACL modules to test for permissions on open/mkdir/opendir.
Ensure that underlying ACLs are returned for directories/files with

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).
