From 3b0dc529f56b5f2328244130683210be98f16f7f Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Thu, 23 Jun 2022 14:00:15 +0200 Subject: ipv6: take care of disable_policy when restoring routes When routes corresponding to addresses are restored by fixup_permanent_addr(), the dst_nopolicy parameter was not set. The typical use case is a user that configures an address on a down interface and then put this interface up. Let's take care of this flag in addrconf_f6i_alloc(), so that every callers benefit ont it.
