Revision be7a010d6fa33dca9327ad8e91844278dfd1e712 authored by Duan Jiong on 15 May 2014, 07:56:14 UTC, committed by David S. Miller on 16 May 2014, 03:26:27 UTC
RFC 4861 states in 7.2.5: The IsRouter flag in the cache entry MUST be set based on the Router flag in the received advertisement. In those cases where the IsRouter flag changes from TRUE to FALSE as a result of this update, the node MUST remove that router from the Default Router List and update the Destination Cache entries for all destinations using that neighbor as a router as specified in Section 7.3.3. This is needed to detect when a node that is used as a router stops forwarding packets due to being configured as a host. Currently, when dealing with NA Message which IsRouter flag changes from TRUE to FALSE, the kernel only removes router from the Default Router List, and don't update the Destination Cache entries. Now in order to update those Destination Cache entries, i introduce function rt6_clean_tohost().
