net.server_epoll: Add option to defer accept() until data available This is a Linux(?) socket option that delays the accept signal until there is data available to read. E.g. with HTTP this might mean that a whole request can be handled without going back trough another turn of the main loop, and an initial client <stream> can be responded to. This may have effects on latency and resource use, as the server does not need to allocate resources until really needed.

net.server_epoll: Wrap LuaSocket object earlier to reuse option setting method Since it provides some protection and error handling in the form of logging.

net.server_epoll: Move call to refresh remote IP address out of wrapper Reduces the side effects of wrapsocket()

net.server_epoll: Add support for TCP Fast Open Requires a patch to LuaSocket adding this socket option, https://github.com/lunarmodules/luasocket/pull/378 sysctl tweaks net.ipv4.tcp_fastopen=3 net.ipv4.tcp_fastopen_blackhole_timeout_sec = 0 net.ipv4.tcp_fastopen_key=$(</proc/sys/kernel/random/uuid) Disabled by default since it an advanced performance tweak unlikely to be needed by most servers.

net.unbound: Adjust log level of error to error to error This error is an error, therefore it should be at the error level

net.unbound: Disable use of hosts file by default (fixes #1737) This mirrors the behaviour with net.dns and avoids the initialization issue in #1737
