Name:Return true if VAL is compared with a s64 sign extended from s32, and they* are with the same signedness.
Proto:static bool cmp_val_with_extended_s64(s64 sval, struct bpf_reg_state *reg)
Type:bool
Parameter:
| Type | Parameter | Name |
|---|---|---|
| s64 | sval | |
| struct bpf_reg_state * | reg |
| 5558 | Return sval >= 0 && minimum possible (s64)value >= 0 && maximum possible (s64)value <= S32_MAX || sval < 0 && maximum possible (s64)value <= 0 && minimum possible (s64)value >= S32_MIN |
| Name | Describe |
|---|---|
| reg_set_min_max | Adjusts the register min/max values in the case that the dst_reg is the* variable register that we are working on, and src_reg is a constant or we're* simply doing a BPF_K check.* In JEQ/JNE cases we also adjust the var_off values. |
| reg_set_min_max_inv | Same as above, but for the case that dst_reg holds a constant and src_reg is* the variable reg. |
