From acb54e3cba404c20f07733f3222c0418a7724a5b Mon Sep 17 00:00:00 2001 From: David Ahern Date: Tue, 17 Apr 2018 17:33:22 -0700 Subject: net/ipv6: Add gfp_flags to route add functions Most FIB entries can be added using memory allocated with GFP_KERNEL. Add gfp_flags to ip6_route_add and addrconf_dst_alloc. Code paths that can be reached from the packet path (e.g., ndisc and autoconfig) or atomic notifiers use GFP_ATOMIC; paths from user context (adding addresses and routes) use GFP_KERNEL.
