4.17-stable review patch. If anyone has any objections, please let me know. ------------------ From: Cong Wang <xiyou.wangcong@xxxxxxxxx> commit 3aa1409a7b160f9444945c0df1cb079df82be84e upstream. tbl->entries is not initialized after kmalloc(), therefore causes an uninit-value warning in ip_vs_lblc_check_expire() as reported by syzbot.
