[PATCH openEuler-1.0-LTS] bpf: Verifer, adjust_scalar_min_max_vals to always call update_reg_bounds()
by Yang Yingliang 22 Feb '22

22 Feb '22

From: John Fastabend <john.fastabend(a)gmail.com> mainline inclusion from mainline-v5.7-rc1 commit 294f2fc6da27620a506e6c050241655459ccd6bd category: bugfix bugzilla: NA CVE: CVE-2021-4159 ----------------------------------------------- Currently, for all op verification we call __red_deduce_bounds() and __red_bound_offset() but we only call __update_reg_bounds() in bitwise ops. However, we could benefit from calling __update_reg_bounds() in BPF_ADD, BPF_SUB, and BPF_MUL cases as well. For example, a register with state 'R1_w=invP0' when we subtract from it, w1 -= 2 Before coerce we will now have an smin_value=S64_MIN, smax_value=U64_MAX and unsigned bounds umin_value=0, umax_value=U64_MAX. These will then be clamped to S32_MIN, U32_MAX values by coerce in the case of alu32 op as done in above example. However tnum will be a constant because the ALU op is done on a constant. Without update_reg_bounds() we have a scenario where tnum is a const but our unsigned bounds do not reflect this. By calling update_reg_bounds after coerce to 32bit we further refine the umin_value to U64_MAX in the alu64 case or U32_MAX in the alu32 case above.
