From f5ba2d32170679eb9b7c251ac3d9687916a41c18 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Thu, 17 Apr 2008 23:19:55 -0700 Subject: [PATCH] [PKT_SCHED]: Fix datalen check in tcf_simp_init(). datalen is unsigned so it can never be less than zero, but that's ok because the attribute passed to nla_len() has been validated and therefore a negative return value is impossible.
