From: David Ahern Date: Tue, 8 Aug 2017 21:51:02 +0000 (-0600) Subject: net: ipv6: lower ndisc notifier priority below addrconf X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6eb7939371104e4ff78261c165c6f33ff6d90031;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git net: ipv6: lower ndisc notifier priority below addrconf ndisc_notify is used to send unsolicited neighbor advertisements (e.g., on a link up). Currently, the ndisc notifier is run before the addrconf notifer which means NA's are not sent for link-local addresses which are added by the addrconf notifier. Fix by lowering the priority of the ndisc notifier. Setting the priority to ADDRCONF_NOTIFY_PRIORITY - 5 means it runs after addrconf and before the route notifier which is ADDRCONF_NOTIFY_PRIORITY - 10.
