Name:bpf_fill_maxinsns6

Proto:static int bpf_fill_maxinsns6(struct bpf_test *self)

Type:int

Parameter:

TypeParameterName
struct bpf_test *self
197  len = BPF_MAXINSNS
201  insn = kmalloc_array - allocate memory for an array.*@n: number of elements.*@size: element size.*@flags: the type of memory to allocate (see kmalloc).
202  If Not insn Then Return -ENOMEM
205  When i < len - 1 cycle insn[i] = Internal classic blocks for direct assignment (BPF_LD | 32-bit | BPF_ABS, RATIONALE. Negative offsets are invalid in BPF.We use them to reference ancillary data.Unlike introduction new instructions, it does not breakexisting compilers/optimizers. + SKF_AD_VLAN_TAG_PRESENT)
209  insn[len - 1] = Internal classic blocks for direct assignment (BPF_RET | BPF_A, 0)
211  insns = insn
212  len = len
214  Return 0
