When setting base_reachable_time or base_reachable_time_ms on a specific interface through sysctl or netlink, the reachable_time value is not updated. This means that neighbour entries will continue to be updated using the old value until it is recomputed in neigh_period_work (which recomputes the value every 300*HZ). On systems with HZ equal to 1000 for instance, it means 5mins before the change is effective. This patch changes this behavior by recomputing reachable_time after each set on base_reachable_time or base_reachable_time_ms. The new value will become effective the next time the neighbour's timer is triggered. Changes are made in two places: the netlink code for set and the sysctl handling code. For sysctl, I use a proc_handler. The ipv6 network code does provide its own handler but it already refreshes reachable_time correctly so it's not an issue. Any other user of neighbour which provide its own handlers must refresh reachable_time. Signed-off-by: Jean-Francois Remy <jeff@melix.org> Signed-off-by: David S. Miller <davem@davemloft.net> |
