Proto:static bool signed_sub_overflows(s64 a, s64 b)
Type:bool
Parameter:
| Type | Parameter | Name |
|---|---|---|
| s64 | a | |
| s64 | b |
| Name | Describe |
|---|---|
| adjust_ptr_min_max_vals | Handles arithmetic on a pointer and a scalar: computes new min/max and var_off.* Caller should also handle BPF_MOV case separately.* If we return -EACCES, caller may want to try again treating pointer as a* scalar |
| adjust_scalar_min_max_vals | WARNING: This function does calculations on 64-bit values, but the actual* execution may occur on 32-bit values. Therefore, things like bitshifts* need extra checks in the 32-bit case. |
