Chris Palmer	7349b274bd	safeweb: handle mux pattern collisions more generally (#11801) ... Fixes #11800 Signed-off-by: Chris Palmer <cpalmer@tailscale.com>	2 years ago
Andrew Lytvynov	5aa4cfad06	safeweb: detect mux handler conflicts (#11562) ... When both muxes match, and one of them is a wildcard "/" pattern (which is common in browser muxes), choose the more specific pattern. If both are non-wildcard matches, there is a pattern overlap, so return an error. Updates https://github.com/tailscale/corp/issues/8027 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	2 years ago
Patrick O'Doherty	af61179c2f	safeweb: add opt-in inline style CSP toggle (#11551) ... Allow the use of inline styles with safeweb via an opt-in configuration item. This will append `style-src "self" "unsafe-inline"` to the default CSP. The `style-src` directive will be used in lieu of the fallback `default-src "self"` directive.

Patrick O'Doherty	8f27520633	safeweb: init (#11467) ... Updates https://github.com/tailscale/corp/issues/8027 Safeweb is a wrapper around http.Server & tsnet that encodes some application security defaults. Safeweb asks developers to split their HTTP routes into two http.ServeMuxs for serving browser and API-facing endpoints repsectively. It then wraps these HTTP routes with the context-appropriate security controls. safeweb.Server#Serve will serve the HTTP muxes over the provided listener. Caller are responsible for creating and tearing down their application's listeners. Applications being served over HTTPS that wish to implement HTTP redirects can use the Server#HTTPRedirect handler to do so. Signed-off-by: Patrick O'Doherty <patrick@tailscale.com>	2 years ago
