From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Subject: kernel/sysctl.c: fix sizeof argument to match variable name Fix sizeof argument to be the same as the data variable name. Probably a copy/paste error. Mostly harmless since both variables are unsigned int. Fixes kernel bugzilla #197371: Possible access to unintended variable in "kernel/sysctl.c" line 1339 https://bugzilla.kernel.org/show_bug.cgi?id=197371 Link: http://lkml.kernel.org/r/e0d0531f-361e-ef5f-8499-32743ba907e1@xxxxxxxxxxxxx Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Reported-by: Petru Mihancea <petrum@xxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- kernel/sysctl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN kernel/sysctl.c~sysctl-fix-sizeof-argument-to-match-variable-name kernel/sysctl.c --- a/kernel/sysctl.c~sysctl-fix-sizeof-argument-to-match-variable-name +++ a/kernel/sysctl.c @@ -1340,7 +1340,7 @@ static struct ctl_table vm_table[] = { { .procname = "dirtytime_expire_seconds", .data = &dirtytime_expire_interval, - .maxlen = sizeof(dirty_expire_interval), + .maxlen = sizeof(dirtytime_expire_interval), .mode = 0644, .proc_handler = dirtytime_interval_handler, .extra1 = &zero, _ -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
