Subject: Forget addresses of unreachable nodes.
X-Git-Tag: release-1.0.12~18
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=369fe1ab1cbfc3f8305de1faab2e30157378b044;p=oweals%2Ftinc.git

Forget addresses of unreachable nodes.

We clear the cached address used for UDP connections when a node becomes
unreachable. This also prevents host-up scripts from passing the old, cached
address from when the host becomes reachable again from a different address.
