This change will enable reverse proxies to set the X-Forwarded-For header, ensuring that the client's IP address is correctly provided to the target endpoint. This modification is essential for applications that depend on the X-Forwarded-For header for various functionalities, such as authentication, logging, or content customization. * Updated tplcontext.go - set `virtReq.RemoteAddr = "127.0.0.1"` i have made the suggested changes * Apply suggestions from code review * Update modules/caddyhttp/templates/tplcontext.go --------- Co-authored-by: Francis Lavoie <lavofr@gmail.com> * go.mod: Upgrade dependencies incl. x/net/http Possibly important for the HTTP/2 Rapid Reset issue. * fileserver: Add command shortcuts `-l` and `-a` (caddyserver#5854) * encode: Add `application/wasm*` to the default content types (caddyserver#5869) * httpcaddyfile: Enable TLS for catch-all site if `tls` directive is specified (caddyserver#5808) * reverseproxy: Fix retries on "upstreams unavailable" error (caddyserver#5841) * reverseproxy: fix parsing Caddyfile fails for unlimited request/response buffers (caddyserver#5828) * cmd: Fix exiting with custom status code, add `caddy -v` (caddyserver#5874) * Simplify variables for commands * Add --envfile support for adapt command * Carry custom status code for commands to os.Exit() * cmd: add `-v` and `--version` to root caddy command * Add `--envfile` to `caddy environ`, extract flag parsing to func --------- Co-authored-by: Mohammed Al Sahaf <msaa1990@gmail.com> * httpcaddyfile: Sort TLS SNI matcher for deterministic JSON output (caddyserver#5860) * httpcaddyfile: Sort TLS SNI matcher, for deterministic adapt output * Update caddyconfig/httpcaddyfile/httptype.go --------- Co-authored-by: Matt Holt <mholt@users.noreply.github.com> * reverseproxy: Replace health header placeholders (caddyserver#5861) * reverseproxy: Add logging for dynamic A upstreams (caddyserver#5857) * reverseproxy: Fix `least_conn` policy regression (caddyserver#5862) * reverseproxy: Add more debug logs (caddyserver#5793) * reverseproxy: Add more debug logs This makes debug logging very noisy when reverse proxying, but I guess that's the point. This has shown to be useful in troubleshooting infrastructure issues. * Update modules/caddyhttp/reverseproxy/streaming.go Co-authored-by: Francis Lavoie <lavofr@gmail.com> * Update modules/caddyhttp/reverseproxy/streaming.go Co-authored-by: Francis Lavoie <lavofr@gmail.com> * Add opt-in `trace_logs` option * Rename to VerboseLogs --------- Co-authored-by: Francis Lavoie <lavofr@gmail.com> * tls: Add X25519Kyber768Draft00 PQ "curve" behind build tag (caddyserver#5852) … when compiled with cfgo (https://github.com/cloudflare/go). * fileserver: Set canonical URL on browse template (caddyserver#5867) * Browse.html: Add canonical URL and home-link When contents are equal, but maybe just a sort order is different, it is good to add `<link rel="canonical" href="base-path/" />`. This helps search engines propeely index the page. I also added a link to the home page with the name of `{{.Host}}` just above the bread crumbs to make the page clearer. https://paste.tnonline.net/files/28Wun5CQZiqA_Screenshot_20231007_134435_Opera.png * Update browse.html * ci: Force the Go version for govulncheck (caddyserver#5879) * admin: Respond with 4xx on non-existing config path (caddyserver#5870) Co-authored-by: Matt Holt <mholt@users.noreply.github.com> * caddyfile: Fix variadic placeholder false positive when token contains `:` (caddyserver#5883) * cmd: upgrade: resolve symlink of the executable (caddyserver#5891) * httpcaddyfile: Fix TLS automation policy merging with get_certificate (caddyserver#5896) * templates: Clarify `include` args docs, add `.ClientIP` (caddyserver#5898) * core: quic listener will manage the underlying socket by itself (caddyserver#5749) * core: quic listener will manage the underlying socket by itself. * format code * rename sharedQUICTLSConfig to sharedQUICState, and it will now manage the number of active requests * add comment * strict unwrap type * fix unwrap * remove comment * cmd: Add newline character to version string in CLI output (caddyserver#5895) * caddyhttp: Use sync.Pool to reduce lengthReader allocations (caddyserver#5848) * Use sync.Pool to reduce lengthReader allocations Signed-off-by: Harish Shan <140232061+perhapsmaple@users.noreply.github.com> * Add defer putLengthReader to prevent leak Signed-off-by: Harish Shan <140232061+perhapsmaple@users.noreply.github.com> * Cleanup in putLengthReader Co-authored-by: Francis Lavoie <lavofr@gmail.com> --------- Signed-off-by: Harish Shan <140232061+perhapsmaple@users.noreply.github.com> Co-authored-by: Francis Lavoie <lavofr@gmail.com> * core: Apply SO_REUSEPORT to UDP sockets (caddyserver#5725) * core: Apply SO_REUSEPORT to UDP sockets For some reason, 10 months ago when I implemented SO_REUSEPORT for TCP, I didn't realize, or forgot, that it can be used for UDP too. It is a much better solution than using deadline hacks to reuse a socket, at least for TCP. Then mholt/caddy-l4#132 was posted, in which we see that UDP servers never actually stopped when the L4 app was stopped. I verified this using this command: $ nc -u 127.0.0.1 55353 combined with POSTing configs to the /load admin endpoint (which alternated between an echo server and a proxy server so I could tell which config was being used). I refactored the code to use SO_REUSEPORT for UDP, but of course we still need graceful reloads on all platforms, not just Unix, so I also implemented a deadline hack similar to what we used for TCP before. That implementation for TCP was not perfect, possibly having a logical (not data) race condition; but for UDP so far it seems to be working. Verified the same way I verified that SO_REUSEPORT works. I think this code is slightly cleaner and I'm fairly confident this code is effective. * Check error * Fix return * Fix var name * implement Unwrap interface and clean up * move unix packet conn to platform specific file * implement Unwrap for unix packet conn * Move sharedPacketConn into proper file * Fix Windows * move sharedPacketConn and fakeClosePacketConn to proper file --------- Co-authored-by: Weidi Deng <weidi_deng@icloud.com> * httpcaddyfile: Remove port from logger names (caddyserver#5881) Co-authored-by: Matt Holt <mholt@users.noreply.github.com> * templates: Delete headers on `httpError` to reset to clean slate (caddyserver#5905) * go.mod: CVE-2023-45142 Update opentelemetry (caddyserver#5908) * go.mod: Upgrade quic-go to v0.39.1 * caddyhttp: Adjust `scheme` placeholder docs (caddyserver#5910) * Upgrade acmeserver to github.com/go-chi/chi/v5 (caddyserver#5913) This commit upgrades the router used in the acmeserver to github.com/go-chi/chi/v5.
