Release 2025.7.0

TUN-9540: Use numeric user id for Dockerfiles
## Summary This commit changes the USER instruction in our Dockerfiles from using the string "nonroot" to its numeric ID "65532". This change is necessary because Kubernetes does not support string-based user IDs in security contexts, requiring numeric IDs instead. The nonroot user maps to 65532 in distroless images.

-Notes:
-
-1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html).
-2. The application can get the type of a received data message by implementing
-   a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#Codec.Marshal)
-   function.
-3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries.
-  Read returns when the input buffer is full or a frame boundary is
-  encountered. Each call to Write sends a single frame message. The Gorilla
-  io.Reader and io.WriteCloser operate on a single WebSocket message.

João "Pisco" Fernandes	ae197908be	TUN-9540: Use numeric user id for Dockerfiles ## Summary This commit changes the USER instruction in our Dockerfiles from using the string "nonroot" to its numeric ID "65532". This change is necessary because Kubernetes does not support string-based user IDs in security contexts, requiring numeric IDs instead. The nonroot user maps to 65532 in distroless images.	2025-07-03 11:31:04 +01:00

Closes TUN-9161	2025-07-01 12:24:59 +01:00
Devin Carr	398da8860f	TUN-9473: Add --dns-resolver-addrs flag To help support users with environments that don't work well with the DNS local resolver's automatic resolution process for local resolver addresses, we introduce a flag to provide them statically to the runtime. When providing the resolver addresses, cloudflared will no longer lookup the DNS resolver addresses and use the user input directly. When provided with a list of DNS resolvers larger than one, the resolver service will randomly select one at random for each incoming request. Closes TUN-9473	2025-06-30 15:20:32 -07:00
Devin Carr	70ed7ffc5f	TUN-9470: Add OriginDialerService to include TCP Adds an OriginDialerService that takes over the roles of both DialUDP and DialTCP towards the origin. This provides the possibility to leverage dialer "middleware" to inject virtual origins, such as the DNS resolver service. DNS Resolver service also gains access to the DialTCP operation to service TCP DNS requests. Minor refactoring includes changes to remove the needs previously provided by the warp-routing configuration. This configuration cannot be disabled by cloudflared so many of the references have been adjusted or removed. Closes TUN-9470	2025-06-30 13:24:16 -07:00
Devin Carr	9ca8b41cf7	TUN-9472: Add virtual DNS service Adds a new reserved service to route UDP requests towards the local DNS resolver. Closes TUN-9472	2025-06-27 13:09:29 -07:00
Devin Carr	b4a98b13fe	TUN-9469: Centralize UDP origin proxy dialing as ingress service Introduces a new `UDPOriginProxy` interface and `UDPOriginService` to standardize how UDP connections are dialed to origins. Allows for future overrides of the ingress service for specific dial destinations. Simplifies dependency injection for UDP dialing throughout both datagram v2 and v3 by using the same ingress service. Previous invocations called into a DialUDP function in the ingress package that was a light wrapper over `net.DialUDP`. Now a reference is passed into both datagram controllers that allows more control over the DialUDP method. Closes TUN-9469	2025-06-23 18:01:15 +00:00
