From 93531c6743157d7e8c5792f8ed1a57641149d62c Mon Sep 17 00:00:00 2001 From: David Ahern Date: Tue, 17 Apr 2018 17:33:25 -0700 Subject: net/ipv6: separate handling of FIB entries from dst based routes Last step before flipping the data type for FIB entries: - use fib6_info_alloc to create FIB entries in ip6_route_info_create and addrconf_dst_alloc - use fib6_info_release in place of dst_release, ip6_rt_put and rt6_release - remove the dst_hold before calling __ip6_ins_rt or ip6_del_rt - when purging routes, drop per-cpu routes - replace inc and dec of rt6i_ref with fib6_info_hold and fib6_info_release - use rt->from since it points to the FIB entry - drop references to exception bucket, fib6_metrics and per-cpu from dst entries (those are relevant for fib entries only) Signed-off-by: David Ahern Signed-off-by: David S.
