Mateusz Jurczyk ac8f07408a NFC: Add sockaddr length checks before accessing sa_family in bind handlers 
commit f6a5885fc4d68e7f25ffb42b9d8d80aebb3bacbb upstream.

Verify that the caller-provided sockaddr structure is large enough to
contain the sa_family field, before accessing it in bind() handlers of the
AF_NFC socket. Since the syscall doesn't enforce 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.
