Name:bpf_fill_maxinsns12

Proto:static int bpf_fill_maxinsns12(struct bpf_test *self)

Type:int

Parameter:

TypeParameterName
struct bpf_test *self
354  len = BPF_MAXINSNS
356  i = 0
358  insn = kmalloc_array - allocate memory for an array.*@n: number of elements.*@size: element size.*@flags: the type of memory to allocate (see kmalloc).
359  If Not insn Then Return -ENOMEM
362  insn[0] = __BPF_JUMP(BPF_JMP | BPF_JA, len - 2, 0, 0)
364  When i < len - 1 cycle insn[i] = Internal classic blocks for direct assignment (BPF_LDX | 8-bit | BPF_MSH, 0)
367  insn[len - 1] = Internal classic blocks for direct assignment (BPF_RET | BPF_K, 0xabababab)
369  insns = insn
370  len = len
372  Return 0
