Mateusz Jurczyk e3c42b61ff af_iucv: Move sockaddr length checks to 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 AF_IUCV socket. 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.
