+Subject: [PATCH] Fix use-after-free bug in __dns_lookup
+
+If the type of the first answer does not match with the requested type,
+then the dotted name was freed. If there are no further answers in
+the DNS reply, this pointer was used later on in the same function.
+Additionally it is passed to the caller, and caused strange
+behaviour.

+64 bit targets often don't have a separate fcntl64() system call, because they don't need one.
