From 73417f617a93cf30342c3ea41abc38927bd467aa Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Tue, 27 Mar 2007 13:56:52 -0700 Subject: [NET] fib_rules: Flush route cache after rule modifications The results of FIB rules lookups are cached in the routing cache except for IPv6 as no such cache exists. So far, it was the responsibility of the user to flush the cache after modifying any rules. This lead to many false bug reports due to misunderstanding of this concept. This patch automatically flushes the route cache after inserting or deleting a rule. Thanks to Muli Ben-Yehuda for catching a bug in the previous patch.
