(cherry picked from commit 8c28c12702c0935a852c7fed6565987623f09fee)
Why? This makes the negative mapping condition (is_null_sid) more
explicit in the code.
The callers in lookup_sid initialized "psid" anyway before, and the ones
in wb_xids2sids now do as well. This is more in line with other APIs we
have: Only touch output parameters if you have something to say.

We basically must process the Owner Rights ACEs as any other ACE wrt to the
order of adding granted permissions and checking denied permissions. According
to MS-DTYP 2.5.3.2 Owner Rights ACEs must be evaluated in the main loop over
the ACEs in an ACL and the corresponding access_mask must be directly applied
to bits_remaining. We currently defer this to after the loop over the ACEs in
ACL, this is wrong.
We just have to do some initial magic to determine if an ACL contains and
Owner Rights ACEs, and in case it doesn't we grant SEC_STD_WRITE_DAC |
SEC_STD_READ_CONTROL at the *beginning*. MS-DTYP:
-- the owner of an object is always granted READ_CONTROL and WRITE_DAC.
CALL SidInToken(Token, SecurityDescriptor.Owner, PrincipalSelfSubst)
IF SidInToken returns True THEN
IF DACL does not contain ACEs from object owner THEN
Remove READ_CONTROL and WRITE_DAC from RemainingAccess

This is needed in preparation of moving the step to update the idmap
cache from the per-idmap-domain callback wb_xids2sids_dom_done() to the
top-level callback wb_xids2sids_done().
Currently the sequence of action is:
* check cache, if not found:
* ask backends
* cache result from backend
* return results
Iow, if we got something from the cache, we don't write the cache.
The next commit defers updating the cache to the top-level callback, so
the sequence becomes
* check cache, if not found:
* ask backends
* cache results
* return results
This has two problems:
* it needlessly writes to the cache what we just got from it
* it possibly overwrites the ID_TYPE_BOTH for a SID-to-xid mapping in
the following case:
- existing ID_TYPE_BOTH mapping in the cache, eg:
IDMAP/SID2XID/S-1-5-21-2180672342-2513613279-2566592647-512 -> Value: 3000000:B
- someone calls wb_xids2sids_send() with xid.id=3000000,xid.type=ID_TYPE_GID
- cache lookup with idmap_cache_find_gid2sid() succeeds
- when caching results we'd call idmap_cache_set_sid2unixid() with the
callers xid.type=ID_TYPE_GID, so idmap_cache_set_sid2unixid() will
overwrite the SID-to-xid mapping with ID_TYPE_GID

level callback wb_xids2sids_done(), not in the per-idmap-domain callback
wb_xids2sids_dom_done().
When caching the mapping we need the id-type from the backend, so we
need a way to pass up that information from wb_xids2sids_dom_done() up
to wb_xids2sids_done()
The xids array copy gets passed from wb_xids2sids_send() to
wb_xids2sids_dom_send(), so wb_xids2sids_dom_done() can then directly
update the top-level copy.

Originally added for BUG: https://bugzilla.samba.org/show_bug.cgi?id=13584
to demonstrate a lock order violation, this test
exposed problems in the mapping of SMB1/2 share modes
and open modes to NetATalk modes once we moved to OFD locks.
Change the test slightly (and add comments)
so it demonstrates working NetATalk share modes
on an open file.

(cherry picked from commit 28990e4ba23695ecf264117efad90cc4e573302e)
This exhibited itself as a problem with OFD locks reported
as:
BUG: https://bugzilla.samba.org/show_bug.cgi?id=13770
However, due to underlying bugs in the vfs_fruit
code the file locks were not being properly applied.
There are two problems in fruit_check_access().
Problem #1:
Inside fruit_check_access() we have:
flags = fcntl(fsp->fh->fd, F_GETFL);
..
if (flags & (O_RDONLY|O_RDWR)) {
We shouldn't be calling fcntl(fsp->fh->fd, ..) directly.
fsp->fh->fd may be a made up number from an underlying
VFS module that has no meaning to a system call.
Secondly, in all POSIX systems - O_RDONLY is defined as
*zero*. O_RDWR = 2.
Which means flags & (O_RDONLY|O_RDWR) becomes (flags & 2),
not what we actually thought.
Problem #2:
deny_mode is *not* a bitmask, it's a set of discrete values.
Inside fruit_check_access() we have:
if (deny_mode & DENY_READ) and also (deny_mode & DENY_WRITE)
However, deny modes are defined as:
/* deny modes */
define DENY_DOS 0
define DENY_ALL 1
define DENY_WRITE 2
define DENY_READ 3
define DENY_NONE 4
define DENY_FCB 7
so if deny_mode = DENY_WRITE, or if deny_mode = DENY_READ
then it's going to trigger both the if (deny_mode & DENY_READ)
*and* the (deny_mode & DENY_WRITE) conditions.
These problems allowed the original test test_netatalk_lock code to
pass (which was added for BUG: https://bugzilla.samba.org/show_bug.cgi?id=13584
to demonstrate the lock order violation).
This patch refactors the fruit_check_access()
code to be much simpler (IMHO) to understand.
Firstly, pass in the SMB1/2 share mode, not old
DOS deny modes.
Secondly, read all the possible NetAtalk locks
into local variables:
netatalk_already_open_for_reading
netatalk_already_open_with_deny_read
netatalk_already_open_for_writing
netatalk_already_open_with_deny_write
Then do the share mode/access mode checks
with the requested values against any stored
netatalk modes/access modes.
Finally add in NetATalk compatible locks
that represent our share modes/access modes
into the file, with an early return if we don't
have FILE_READ_DATA (in which case we can't
write locks anyway).
The patch is easier to understand by looking
at the completed patched fruit_check_access()
function, rather than trying to look at the
diff.
