This commit fix the problems that arose when moving the dns_message_t object from fetchctx_t to the query structure. Since the lifetime of query objects are different than that of a fetchctx and the dns_message_t object held by the query may be being used by some external module, e.g. validator, even after the query may have been destroyed, propery handling of the references to the message were added in this commit to avoid accessing an already destroyed object. Specifically, in resquery_response(), a reference to the message is attached at the beginning of the function and detached at the end, since a possible call to fctx_cancelquery() would release the dns_message_t object, and in the next lines of code a call to add_bad() would require a valid pointer to the same object. In valcreate() a new reference is attached to the message object, this ensures that if the corresponding query object is destroyed before the validator attempts to access it, no invalid pointer access occurs. In validated() we have to attach a new reference to the message, since we destroy the validator object at the beginning of the function, and we need access to the message in the next lines of the same function. |
