store_trace

Name:Store the value of each argument

Proto:static inline __attribute__((__always_inline__)) void store_trace_args(void *data, struct trace_probe *tp, struct pt_regs *regs, int header_size, int maxlen)

Type:void

Parameter:

Type	Parameter	Name
void *	data
struct trace_probe *	tp
struct pt_regs *	regs
int	header_size
int	maxlen

195

base = data - header_size

196

dyndata = data + trace entry size

200

When i < nr_args cycle

201

arg = args + i

202

dl = data + Offset from argument entry

204

If Value for the false possibility is greater at compile time( Dynamic array (string) is used ) Then dl = data_loc: data location, compatible with u32 (maxlen, dyndata - base)

206

ret = Note that we don't verify it, since the code does not come from user space

207

If Value for the false possibility is greater at compile time(ret < 0 && Dynamic array (string) is used ) Then

208

dl = data_loc: data location, compatible with u32 (0, dyndata - base)

209

Else

210

dyndata += ret

211

maxlen -= ret
