From d3ba1767743d3b6f9d591fd59cc8f401d8fccbf3 Mon Sep 17 00:00:00 2001 From: Dmitry Valter Date: Tue, 22 Feb 2022 06:40:22 +0000 Subject: fib: fix mpls db label overflow mpls fib DB size was 2^20 instead of intended 2^21. Therefore large mpls labels caused DB to overflow and write to other tables or some random objects. Or crash with ASAN. Sometimes.
