From db2b7cd8f8489e8c4a55d7556b61282c7b7cc98d 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: Willy Tarreau --- kernel/sysctl.c | 1 + 1 file changed, 1 insertion(+) diff --git a/kernel/sysctl.c b/kernel/sysctl.c index 4fd49fe1046df..430725da89d07 100644 --- a/kernel/sysctl.c +++ b/kernel/sysctl.c @@ -2224,6 +2224,7 @@ 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; -- 2.47.2
