dns_server: Be strict when constructing a LDB DN from an untrusted DNS name
This changes our DNS server to be much more careful when constructing DNS names

CVE-2018-10919 tests: Add extra test for dirsync deleted object corner-case
The acl_read.c code contains a special case to allow dirsync to
work-around having insufficient access rights. We had a concern that
the dirsync module could leak sensitive information for deleted objects.
This patch adds a test-case to prove whether or not this is happening.
The new test case is similar to the existing dirsync test except:
- We make the confidential attribute also preserve-on-delete, so it
hangs around for deleted objcts. Because the attributes now persist
across test case runs, I've used a different attribute to normal.
(Technically, the dirsync search expressions are now specific enough
that the regular attribute could be used, but it would make things
quite fragile if someone tried to add a new test case).
- To handle searching for deleted objects, the search expressions are
now more complicated. Currently dirsync adds an extra-filter to the
'!' searches to exclude deleted objects, i.e. samaccountname matches
the test-objects AND the object is not deleted. We now extend this to
include deleted objects with lastKnownParent equal to the test OU.
The search expression matches either case so that we can use the same
expression throughout the test (regardless of whether the object is
deleted yet or not).
This test proves that the dirsync corner-case does not actually leak
sensitive information on Samba. This is due to a bug in the dirsync
code - when the buggy line is removed, this new test promptly fails.
Test also passes against Windows.

CVE-2018-10919 acl_read: Fix unauthorized attribute access via searches
A user that doesn't have access to view an attribute can still guess the
attribute's value via repeated LDAP searches. This affects confidential
attributes, as well as ACLs applied to an object/attribute to deny
access.
Currently the code will hide objects if the attribute filter contains an
attribute they are not authorized to see. However, the code still
returns objects as results if confidential attribute is in the search
expression itself, but not in the attribute filter.
To fix this problem we have to check the access rights on the attributes
in the search-tree, as well as the attributes returned in the message.
Points of note:
- I've preserved the existing dirsync logic (the dirsync module code
suppresses the result as long as the replPropertyMetaData attribute is
removed). However, there doesn't appear to be any test that highlights
that this functionality is required for dirsync.
- To avoid this fix breaking the acl.py tests, we need to still permit
searches like 'objectClass=*', even though we don't have Read Property
access rights for the objectClass attribute. The logic that Windows
uses does not appear to be clearly documented, so I've made a best
guess that seems to mirror Windows behaviour.

CVE-2018-10919 security: Fix checking of object-specific CONTROL_ACCESS rights
An 'Object Access Allowed' ACE that assigned 'Control Access' (CR)
rights to a specific attribute would not actually grant access.
What was happening was the remaining_access mask for the object_tree
nodes would be Read Property (RP) + Control Access (CR). The ACE mapped
to the schemaIDGUID for a given attribute, which would end up being a
child node in the tree. So the CR bit was cleared for a child node, but
not the rest of the tree. We would then check the user had the RP access
right, which it did. However, the RP right was cleared for another node
in the tree, which still had the CR bit set in its remaining_access
bitmap, so Samba would not grant access.
Generally, the remaining_access only ever has one bit set, which means
this isn't a problem normally. However, in the Control Access case there
are 2 separate bits being checked, i.e. RP + CR.
One option to fix this problem would be to clear the remaining_access
for the tree instead of just the node. However, the Windows spec is
actually pretty clear on this: if the ACE has a CR right present, then
you can stop any further access checks.

CVE-2018-10919 tests: Add test case for object visibility with limited rights
Currently Samba is a bit disclosive with LDB_OP_PRESENT (i.e.
attribute=*) searches compared to Windows.
All the acl.py tests are based on objectClass=* searches, where Windows
will happily tell a user about objects they have List Contents rights,
but not Read Property rights for. However, if you change the attribute
being searched for, suddenly the objects are no longer visible on
Windows (whereas they are on Samba).
This is a problem, because Samba can tell you about which objects have
confidential attributes, which in itself could be disclosive.
This patch adds a acl.py test-case that highlights this behaviour. The
test passes against Windows but fails against Samba.

s3/utils: fix regression where specifying -Unetbios/root works
Usually you need to be root on a linux server to modify quotas. Even
with a linux server joined to a windows AD you could always log in as
local root with smbcquotas. However in recent builds this has changed.
This patch fixes this

s3/smbd: Don't stat when doing a quota operation (as it's a fake file)
calling SMB_VFS_STAT on the quota fake file fails and caused
FS_INFO/FileFsControlInfo request to error out early, in turn stopped a
Win8.1 client from proceeding with quota queries.
Calling parse_user_quota_list with a NULL buffer can cause a panic, while
this shouldn't happen, I managed to trigger this with an early implementation
of SMB2 quota support in smbd which didn't pass back NT_STATUS_NO_MORE_ENTRIES
when handling a SMB2_0_INFO_QUOTA GETINFO message.
OTHOH the Windows client handled the same situation gracefully.
smb2_query_directory: make 'return true' explicit in smb2_query_directory_next_entry()
'return req' should do the same as 'return true' for a bool function,
it's implicitly expanded as 'return (req!=NULL)?true:false.
There's no point in that as 'req' is always a valid pointer.
This was most likely just a copy and paste bug.
So we make this explicit now and avoid that Coverity reports this:
CID 1438158: Null pointer dereferences (REVERSE_INULL)
Null-checking "req" suggests that it may be null, but it has already
been dereferenced on all paths leading to the check.
