hi,
i want to modify the RREP message packet in MAODV. i add one variable and
one array in the packet as below :
struct hdr_aodv_reply {
u_int8_t rp_type; // Packet Type
/*** modified for multicast ***/
//u_int8_t reserved[2];
u_int8_t rp_flags;
u_int8_t reserved;
/*******************************/
u_int8_t rp_hop_count; // Hop Count
nsaddr_t rp_dst; // Destination IP Address
u_int32_t rp_dst_seqno; // Destination Sequence Number
nsaddr_t rp_src; // Source IP Address
double rp_lifetime; // Lifetime
double rp_timestamp; // when corresponding REQ sent;
/********add for me************/
double rp_S;
nsaddr_t rp_pt[5];
/******************************/
inline int size() {
int sz = 0;
/*
sz = sizeof(u_int8_t) // rp_type
+ 2*sizeof(u_int8_t) // rp_flags + reserved
+ sizeof(u_int8_t) // rp_hop_count
+ sizeof(double) // rp_timestamp
+ sizeof(nsaddr_t) // rp_dst
+ sizeof(u_int32_t) // rp_dst_seqno
+ sizeof(nsaddr_t) // rp_src
+ sizeof(u_int32_t); // rp_lifetime
*/
sz = 6*sizeof(u_int32_t)+sizeof(double)+5*sizeof(nsaddr_t);
assert (sz >= 0);
return sz;
}
the error is :segmentation falt (core dumped)
thanks for help me.
