SECURITY: middleware.ClientIP, a replacement for middleware.RealIP

PR #​967 introduced middleware.ClientIP, a replacement for middleware.RealIP that closes the three open spoofing advisories:

• GHSA-9g5q-2w5x-hmxf — IP spoofing via XFF in RemoteAddr resolution (convto)
• GHSA-rjr7-jggh-pgcp — RealIP allows IP spoofing via unvalidated XFF (rezmoss)
• GHSA-3fxj-6jh8-hvhx — IP spoofing in middleware.RealIP (Saku0512, Critical / 9.3)

It also addresses issues outlined at:

• #​708
• https://adam-p.ca/blog/2022/03/x-forwarded-for/
• #​711
• #​453
• #​908

middleware.RealIP is deprecated in this PR with pointers to the new API.

The deprecation only adds a // Deprecated: doc comment; the function keeps working for backward compatibility.

Why a new middleware (not "fix RealIP in place")

RealIP has two unfixable design choices: it mutates r.RemoteAddr, and it tries to be a one-size-fits-all default by walking a hard-coded list of headers any client can supply. Per adam-p's "The perils of the 'real' client IP" (which calls chi out by name on this), there is no safe default — the user must pick their trust source explicitly.

The new API

Four middlewares, two accessors. Pick exactly one middleware based on your
infrastructure, read the result with one of the two accessors:

// One of the four. There is no safe default — pick exactly one.
func ClientIPFromHeader(trustedHeader string) func(http.Handler) http.Handler
func ClientIPFromXFF(trustedIPPrefixes ...string) func(http.Handler) http.Handler
func ClientIPFromXFFTrustedProxies(numTrustedProxies int) func(http.Handler) http.Handler
func ClientIPFromRemoteAddr(h http.Handler) http.Handler

// Read the result.
func GetClientIP(ctx context.Context) string         // for logs, rate-limit keys
func GetClientIPAddr(ctx context.Context) netip.Addr // for typed work

Example usage:

// Pick a single ClientIP middleware based on your deployment
  
// Cloudflare.
r.Use(middleware.ClientIPFromHeader("CF-Connecting-IP"))

// Nginx with ngx_http_realip_module.
r.Use(middleware.ClientIPFromHeader("X-Real-IP"))

// Apache with mod_remoteip.
r.Use(middleware.ClientIPFromHeader("X-Client-IP"))

// AWS CloudFront, or any proxy fleet with known CIDRs.
r.Use(middleware.ClientIPFromXFF(
    "13.32.0.0/15",   // CloudFront IPv4
    "52.46.0.0/18",   // CloudFront IPv4
    "2600:9000::/28", // CloudFront IPv6
))

// Behind exactly 2 trusted proxies with dynamic IPs (autoscaling pools,
// ephemeral containers, dynamic CDN edges).
r.Use(middleware.ClientIPFromXFFTrustedProxies(2))

// Server directly on the public internet, no proxy in front.
r.Use(middleware.ClientIPFromRemoteAddr)

And in your handler or downstream middleware:

clientIP := middleware.GetClientIP(r.Context())
// log it, use it as a rate-limit key, etc.

What's Changed

• middleware: add Discard method to WrapResponseWriter by @​patrislav in #​926
  • Adds Discard() method to the middleware.WrapResponseWriter interface. This is technically an API breaking change. However after some discussion at #​926 (comment), we decided to move forward, and release as minor version, as we don't expect anyone to rely on this interface / implement it externally.
