Chris Palmer	7349b274bd	safeweb: handle mux pattern collisions more generally (#11801) ... Fixes #11800 Signed-off-by: Chris Palmer <cpalmer@tailscale.com>	7 months ago
Chris Palmer	bdfaef4879	safeweb: allow object-src: self in CSP (#11782) ... This change is safe (self is still safe, by definition), and makes the code match the comment. Updates #cleanup Signed-off-by: Chris Palmer <cpalmer@tailscale.com>	7 months ago
Chris Palmer	88a7767492	safeweb: set SameSite=Strict, with an option for Lax (#11781) ... Fixes #11780 Signed-off-by: Chris Palmer <cpalmer@tailscale.com>	7 months ago
Patrick O'Doherty	1535d0feca	safeweb: move http.Serve for HTTP redirects into lib (#11592) ... Refactor the interaction between caller/library when establishing the HTTP to HTTPS redirects by moving the call to http.Serve into safeweb. This makes linting for other uses of http.Serve easier without having to account for false positives created by the old interface.

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.

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	b60c4664c7	safeweb: return http.Handler from safeweb.RedirectHTTP (#11538) ... Updates #cleanup Change the return type of the safeweb.RedirectHTTP method to a handler that can be passed directly to http.Serve without any http.HandlerFunc wrapping necessary.

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>	8 months ago
