6lowpan: Fix null pointer dereference in UDP uncompression function When a UDP packet gets fragmented, a crash will occur at reassembly time. This is because skb->transport_header is not set during earlier period of fragment reassembly. As a consequence, call to udp_hdr() return NULL and uh (which is NULL) gets dereferenced without much test. Signed-off-by: Tony Cheneau <tony.cheneau@amnesiak.org> Signed-off-by: David S.
