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.

local xpcall = xpcall;

if select(2, xpcall(function (x) return x end, function () end,  "test")) ~= "test" then
	xpcall = require"util.compat".xpcall;
end

return {
	xpcall = xpcall;
};
