函数名称:he scalar precision tracking algorithm:* . at the start all registers have precise=false.* . scalar ranges are tracked as normal through alu and jmp insns.* . once precise value of the scalar register is used in:* . ptr + scalar alu*
函数原型:static void mark_all_scalars_precise(struct bpf_verifier_env *env, struct bpf_verifier_state *st)
返回类型:void
参数:
类型 | 参数 | 名称 |
---|---|---|
struct bpf_verifier_env * | env | |
struct bpf_verifier_state * | st |
1709 | func等于 call stack tracking [i] |
1710 | 以j小于BPF_REG_FP循环 |
1712 | 如果 Ordering of fields matters. See states_equal() 不等于g doesn't contain a valid pointer 则继续下一循环 |
1717 | 如果slot_type[0]不等于 register spilled into stack 则继续下一循环 |
1719 | reg等于spilled_ptr |
1720 | 如果 Ordering of fields matters. See states_equal() 不等于g doesn't contain a valid pointer 则继续下一循环 |
