Overview ¶

Package loopbackhost is the one rule for a Host header that names the loopback interface (cockpit#req:host-header-check). Cockpit's guard and the dashboard's own routes on the same listener both ask it, so that a page which rebinds DNS to the loopback address is refused by one rule and not by two that could drift apart.

Functions ¶

func Named ¶

func Named(host string) bool

Named reports whether a host (a Host header's host part, or the host of a listen address) names the loopback interface: exactly the name localhost (in any case, with no trailing dot), any IPv4 address of 127.0.0.0/8, and the IPv6 address ::1 in any spelling. The one rule serves the Host check and the daemon's own --listen check, so a daemon cannot listen on a loopback form that its own health check then refuses. Anything else, including a trailing dot name, is refused.

func Request ¶

func Request(request *http.Request) bool

Request reports whether request's Host header names a loopback host.

func Split ¶

func Split(value string) (host, port string)

Split separates a Host header into its host name and optional port. A bracketed IPv6 literal loses its brackets. An empty or malformed value yields an empty host, which Named refuses, as does a port that is present but not a number.
