This bug has apparently existed since the introduction of this function in the pre-git era (4500e917 in Thomas Gleixner's history.git, "[NET]: Add proc_dointvec_userhz_jiffies, use it for proper handling of neighbour sysctls."). As a minimal fix we can simply duplicate the corresponding check in do_proc_dointvec_conv(). Link: http://lkml.kernel.org/r/20190207123426.9202-3-zev@bewilderbeest.netSigned-off-by:
