If we decided not to put a PAC into the ticket, mspac would be NULL
here, and the resulting ticket would not contain a PAC. This could
happen if there was a request to omit the PAC or the service did not
require authorization data. Ensure that we always generate a PAC.

Windows ignores PAC_TYPE_ATTRIBUTES_INFO and always issues a PAC when
presented with an RODC-issued TGT. By removing this PAC buffer from
RODC-issued tickets, we ensure that an RODC-issued ticket will still
result in a PAC if it is first renewed or validated by the main DC.

To use memcpy(), we need to specify the number of bytes to copy, rather
than the number of ldb_val structures.
BUG: https://bugzilla.samba.org/show_bug.cgi?id=15008
Signed-off-by: Joseph Sutton <josephsutton@catalyst.net.nz>
Currently, we can crash the server by sending a large number of values
of a specific attribute (such as sAMAccountName) spread across a few
message elements. If val_count is larger than the total number of
elements, we get an access beyond the elements array.
Similarly, we can include unrelated message elements prior to the
message elements of the attribute in question, so that not all of the
attribute's values are copied into the returned elements values array.
This can cause the server to access uninitialised data, likely resulting
in a crash or unexpected behaviour.

This aims to minimise usage of the error-prone pattern of searching for
a just-added message element in order to make modifications to it (and
potentially finding the wrong element).
BUG: https://bugzilla.samba.org/show_bug.cgi?id=15009
Signed-off-by: Joseph Sutton <josephsutton@catalyst.net.nz>
Currently, there are many places where we use ldb_msg_add_empty() to add
an empty element to a message, and then call ldb_msg_add_value() or
similar to add values to that element. However, this performs an
unnecessary search of the message's elements to locate the new element.
Moreover, if an element with the same attribute name already exists
earlier in the message, the values will be added to that element,
instead of to the intended newly added element.
A similar pattern exists where we add values to a message, and then call
ldb_msg_find_element() to locate that message element and sets its flags
to (e.g.) LDB_FLAG_MOD_REPLACE. This also performs an unnecessary
search, and may locate the wrong message element for setting the flags.
To avoid these problems, add functions for appending a value to a
message, so that a particular value can be added to the end of a message
in a single operation.
For ADD requests, it is important that no two message elements share the
same attribute name, otherwise things will break. (Normally,
ldb_msg_normalize() is called before processing the request to help
ensure this.) Thus, we must be careful not to append an attribute to an
ADD message, unless we are sure (e.g. through ldb_msg_find_element())
that an existing element for that attribute is not present.
These functions will be used in the next commit.

Using the newly added ldb flag, we can now detect when a message has
been shallow-copied so that its elements share their values with the
original message elements. Then when adding values to the copied
message, we now make a copy of the shared values array first.
This should prevent a use-after-free that occurred in LDB modules when
new values were added to a shallow copy of a message by calling
talloc_realloc() on the original values array, invalidating the 'values'
pointer in the original message element. The original values pointer can
later be used in the database audit logging module which logs database
requests, and potentially cause a crash.
