From 328dca1a45bfcbc5ca4792d68330d97a4f7d47b7 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 25 Jan 2017 18:20:55 -0800 Subject: [PATCH] sysctl: fix proc_doulongvec_ms_jiffies_minmax() commit ff9f8a7cf935468a94d9927c68b00daae701667e upstream. We perform the conversion between kernel jiffies and ms only when exporting kernel value to user space. We need to do the opposite operation when value is written by user. Only matters when HZ != 1000 Signed-off-by: Eric Dumazet Signed-off-by: Linus Torvalds Signed-off-by: Ben Hutchings --- kernel/sysctl.c | 1 + 1 file changed, 1 insertion(+) diff --git a/kernel/sysctl.c b/kernel/sysctl.c index f9293694b52a..3a3172559b22 100644 --- a/kernel/sysctl.c +++ b/kernel/sysctl.c @@ -2317,6 +2317,7 @@ static int __do_proc_doulongvec_minmax(void *data, struct ctl_table *table, int break; if (neg) continue; + val = convmul * val / convdiv; if ((min && val < *min) || (max && val > *max)) continue; *i = val; -- 2.34.1
