[Mesh] KRACK attack

You have all probably already heard about the wifi KRACK attack. If not, here is the lowdown: https://www.krackattacks.com/ sudowrt is also affected. What this means is that your private wifi network is... potentially a lot less private. I started work on a fix here: https://github.com/sudomesh/sudowrt-firmware/issues/109 but I ran into a build issue which maybe Grant knows how to fix? https://github.com/sudomesh/sudowrt-firmware/issues/110 Hopefully we can sort this out over the next day or two. In the mean time node-operates may want to disconnect any sensitive devices from their private network. As always you should be using end-to-end encryption for all communications. Install the HTTPS Everywhere <https://www.eff.org/https-everywhere> browser extension if you haven't. For situations where end-to-end encryption is not viable, using a VPN like Mullvad <https://www.mullvad.net/> is a good idea. -- marc/juul
