Tyler Hicks 131a3b82c8 irda: Only insert new objects into the global database via setsockopt ... The irda_setsockopt() function conditionally allocates memory for a new self->ias_object or, in some cases, reuses the existing self->ias_object. Existing objects were incorrectly reinserted into the LM_IAS database which corrupted the doubly linked list used for the hashbin implementation of the LM_IAS database. When combined with a memory leak in irda_bind(), this issue could be leveraged to create a use-after-free vulnerability in the hashbin list. This patch fixes the issue by only inserting newly allocated objects into the database.
