Up to now, get_nt_acl() took a files_struct pointer (fsp) and
a file name. All the underlying functions should need and now
do need (after the previous preparatory work), is a connection_struct
and a file name. The connection_struct is already there in the
vfs_handle passed to the vfs functions. So the files_struct
argument can be eliminated.
This eliminates the need of calling open_file_stat in a couple
of places to produce the fsp needed.

Replace smbd/posix_acls.c:get_nt_acl() by two funcions:
posix_get_nt_acl() and posix_fget_nt_acl(). The first
takes a connection struct and a file name instead of a
files_struct pointer. This is in preparation of changing
the vfs api for SMB_VFS_GET_NT_ACL.

Convert canonicalise_acl() to take connection_struct, is_directory
and file name instead of files_struct pointer.

(This used to be commit d579a7f84f)
Convert ensure_canon_entry_valid() to take share_params and an is_directory
flag instead of an files_struct pointer.
Michael
(This used to be commit bdb208124b)
This is a first change in a series: Pass what is needed instead of files_struct
pointers to some functions. This is in preparation of introducing two variants
of get_nt_acl - one for fname (which does not need an fsp), one for file
descriptor.
This changes apply_default_perms to take share_params (rather thatn snum)
and an is_directory flag instead of an fsp.

The three can_* access check functions in smbd/posix_acls.c that are used in
smbd/open.c and smbd/nttrans.c explicitly called check_posix_acl_group_access()
This lead to errors with nfsv4 acls (ZFS and GPFS).
This changes the can_* functions to get the nt_acl via VFS layer and call
se_access_check on that. It also removes check_posix_acl_group_access()
which has no more callers.
NOTE: The can_* functions should really not be in smbd/posix_acls.c but
in a separate file (I propose smbd/access.c).

bugs in various places whilst doing this (places that assumed
BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).

Why? It moves these structs from the data into the text segment, so they
will never been copy-on-write copied. Not much, but as in German you say
"Kleinvieh macht auch Mist...."

the main server code paths. We should now be able to cope with
paths up to PATH_MAX length now.
Final job will be to add the TALLOC_CTX * parameter to
unix_convert to make it explicit (for Volker).
Jeremy.
(This used to be commit 7f0db75fb0)
This adds the two functions talloc_stackframe() and talloc_tos().
* When a new talloc stackframe is allocated with talloc_stackframe(), then
* the TALLOC_CTX returned with talloc_tos() is reset to that new
* frame. Whenever that stack frame is TALLOC_FREE()'ed, then the reverse
* happens: The previous talloc_tos() is restored.
*
* This API is designed to be robust in the sense that if someone forgets to
* TALLOC_FREE() a stackframe, then the next outer one correctly cleans up and
* resets the talloc_tos().
The original motivation for this patch was to get rid of the
sid_string_static & friends buffers. Explicitly passing talloc context
everywhere clutters code too much for my taste, so an implicit
talloc_tos() is introduced here. Many of these static buffers are
replaced by a single static pointer.
The intended use would thus be that low-level functions can rather
freely push stuff to talloc_tos, the upper layers clean up by freeing
the stackframe. The more of these stackframes are used and correctly
freed the more exact the memory cleanup happens.
This patch removes the main_loop_talloc_ctx, tmp_talloc_ctx and
lp_talloc_ctx (did I forget any?)
So, never do a
tmp_ctx = talloc_init("foo");
anymore, instead, use
tmp_ctx = talloc_stackframe()
:-)

that contains some of the fields from the SMB header, removing the need
to access inbuf directly. This right now is used only in the open file
code & friends, and creating that header is only done when needed. This
needs more work, but it is a start.
Jeremy, I'm only checking this into 3_0, please review before I merge it
to _26.

You don't want to know what I discovered about Windows
ACLs to make this work :-(. See :

Search for "Q. How does Inheritance come into this?"
for details.

should be disallowed. Matches better what W2K3R3 does.
NFSv4 ACL module owners, please examine these changes.

memory leak I introduced into acl code, also remove
redundent extra check for global_sid_System :
global_sid_System == S-1-5-18 which is already
included in the check for a domain of
global_sid_NT_Authority == S-1-5

Allow us to correctly refuse to set delete on close on a
non-empty directory. There are still some delete-on-close
wrinkles to be fixed, but I understand how to do that better
now. I'll fix this tomorrow.

This involved passing the dirname as argument to a few routines instead of
calling parent_dirname() deep down.
Volker
(This used to be commit 7977fd7865)
code is wrong or bad or anything, just that it
needs to be discussed & reviewed on the samba-technical
list before we add a platform-specific NFSv4 mapping.
That way lies a lot of future pain :-).

acls code. I'm pretty sure this was safe, but become_root()
does other things to the token stack that become_root_uid_only()
does not, and as we're going into a vfs redirectred function
I decided it wasn't safe for now.
Jeremy.

become_root_uid_only()

unbecome_root_uid_only()
saving errno across the second call. Most of our internal
change calls can be replaced with these simple calls.

(This used to be commit 4143aa83c0)
modularizes our interface into the special posix API used on
the system. Without this patch the specific API flavor is
determined at compile time, something which severely limits
usability on systems with more than one file system. Our
first targets are AIX with its JFS and JFS2 APIs, at a later
stage also GPFS. But it's certainly not limited to IBM
stuff, this abstraction is also necessary for anything that
copes with NFSv4 ACLs. For this we will check in handling
very soon.

(This used to be commit ca0c73f281)
no way to get all the cases where kernel oplocks are
on and we can't open the file and get the correct
semantics (think about the open with truncate with
an attribute only open - we'd need a vfs change to
add the truncate(fname, len) call). So always drop
the share mode lock before doing any real fd opens and
then re-acquire it afterwards. We're already dealing
with the race in the create case, and we deal with
any other races in the same way. Volker, please
examine *carefully* :-). This should fix the problems
people reported with kernel oplocks being on.
Jeremy.

think this can happen in real life but the code is
too complicated to be sure....
Jerry please merge this for 3.0.23.

* depreacte 'acl group control' after discussion with Jeremy
and implement functionality as part of 'dos filemode'
