Mateusz Jurczyk d2ecfa765d Bluetooth: Add sockaddr length checks before accessing sa_family in bind and connect handlers ...

Verify that the caller-provided sockaddr structure is large enough to
contain the sa_family field, before accessing it in bind() and connect()
handlers of the Bluetooth sockets. Since neither syscall enforces a minimum
size of the corresponding memory region, very short sockaddrs (zero or one
byte long) result in operating on uninitialized memory while referencing
sa_family.
