mod_smacks: Factor out some convenience functions Those lines are long and the risk of mistakes if another one needs to be added seems high, but lower when factored out like this.

util.stanza: Document top level attributes in Teal definition Tells you if you make a typo like "gropchat" or so

util.stanza: Document error conditions in Teal definition Gets you nice error messages if you make a typo in with error_reply()

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
