We basically must process the Owner Rights ACEs as any other ACE wrt to the

to bits_remaining. We currently defer this to after the loop over the ACEs in
ACL, this is wrong.

winbindd: track whether a result from xid2sid was coming from the cache
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:
- 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

winbindd: make a copy of xid's in wb_xids2sids_send()
This is in preparation of setting the result of the mapping in the top-
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.
This only properly covers the small-message nonblocking case. Covering
the large-message and the blocking case is a much larger effort assuming
we want to re-send the failed message if parts of the message has gone
through properly. Don't do that for now.
This was found by sanba_dnsupdate constantly recreating its irpc handle to
winbindd in the RODC case.

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)
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:
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.

ldb: Avoid inefficient one-level searches
Commit 88ae60ed186c9 introduced a problem that made one-level
searches inefficient if there were a lot of child objects in the same
level, and the requested object didn't exist. Basically, it ignored the
case where ldb_kv_index_dn() returned LDB_ERR_NO_SUCH_OBJECT, i.e. the
indexed lookup was successful, but didn't find a match. At which point,
there was no more processing we needed to do.
The behaviour after 88ae60ed186c9 was to fall-through and run the
ldb_kv_index_filter() function over *all* the children. This still
returned the correct result, but could be costly if there were a lot of
children.
The case 88ae60ed186c9 was trying to fix was where we could not do
an indexed search (e.g. trying to match on a 'attribute=*' filter). In
which case we want to ignore the LDB_ERR_OPERATIONS_ERROR and just run
ldb_kv_index_filter() over all the children. This is still more
efficient than the fallback of doing a full database scan.
This patch adds in a short-circuit for the NO_SUCH_OBJECT case, so we
can skip the unnecessary ldb_kv_index_filter() work.

s3:libsmb: cli_smb2_list() can sometimes fail initially on a connection
cli_smb2_list() appears to be a slightly unique SMB operation in that it
specifies the max transaction size for the response buffer size. The
Python bindings highlighted a problem where if cli_smb2_list() were one
of the first operations performed on the SMBv2 connection, it would fail
due to insufficient credits. Because the response buffer size is
(potentially) so much larger, it requires more credits (128) compared
with other SMB operations.
When talking to a samba DC, the connection credits seem to start off at
1, then increase by 32 for every SMB reply we receive back from the
server. After cli_full_connection(), the connection has 65 credits. The
cli_smb2_create_fnum() in cli_smb2_list() adds another 32 credits, but
this is still less than the 128 that smb2cli_query_directory() requires.
This problem doesn't happen for smbclient because the cli_cm_open() API
it uses ends up sending more messages, and so the connection has more
credits.
This patch changes cli_smb2_list(), so it requests a smaller response
buffer size if it doesn't have enough credits available for the max
transaction size. smb2cli_query_directory() is already in a loop, so it
can span multiple SMB messages if for some reason the transaction size
isn't big enough for the listings.

In this case, as the onelevel and subtree sets of records are roughly
