RustDeskandClaude Fable 5.1 978c901f49 port forward: a login's target and challenge travel with its own accept (#16069)
* port forward: mappings take turns at the window's login slots

A window's mappings log in concurrently, and each login is built from
the shared `LoginConfigHandler`: `create_login_msg` reads
`port_forward`, which `listen()` set before connecting, and
`handle_login_from_ui` reads `hash`, which the last `Hash` to arrive
set. Two mappings logging in at once could swap targets, bridging a
local socket to the other's target, and answer each other's challenge,
failing one login. The window's password prompt is broadcast to every
mapping, so one whose `Hash` had not arrived answered with whatever the
handler held.

Each mapping now fills `port_forward` and `hash` and sends its login
under a per-window turn lock, and keeps its own `Hash` beside the
connection: a password typed before it arrived is left to the mapping
that prompted, which stores the salted password in the shared handler
for the others to log in with.

The fix stays in `port_forward.rs`. `LoginConfigHandler` gains the lock
and a setter for its private `hash`; `Interface`, `Session` and the
login functions keep their signatures.

* port forward: the lock and the hash setter are crate-private; test the hash that arrives late on its real path

Both exist only so `port_forward.rs` can reach the handler's private
`hash`; neither is API.

The test for a password typed before a connection's hash ended by
answering the prompt again once the hash was there. What happens in the
code is that the hash's arrival runs `handle_hash`, which logs in with
the password the prompting mapping stored; the test now ends there, with
no preset password. Answering the prompt with one's own challenge while
the handler holds another's is a test of its own.

* port forward: a password typed before the connection's hash answers it when it comes

The previous commit dropped such a password, counting on the mapping
that prompted having stored it in the shared handler by the time this
connection's `Hash` arrived. The broadcast wakes both mappings at once
and `select!` picks between a ready `Hash` and a ready password at
random, so this one could reach `handle_hash` first, find the handler
empty, and prompt again.

The connection keeps the password until its `Hash` arrives and answers
with it then. `login_from_ui` takes the challenge it answers; the wait
is `connect_and_login`'s, in `hash_arrived`.

Dependencies

Desktop versions use Flutter or Sciter (deprecated) for GUI. This tutorial is for Sciter only, since it is easier and more friendly to start. Check out our CI for building the Flutter version.

Please download Sciter dynamic library yourself.

Raw Steps to build

  • Prepare your Rust development env and C++ build env

  • Install vcpkg, and set VCPKG_ROOT env variable correctly

    • Windows: vcpkg install libvpx:x64-windows-static libyuv:x64-windows-static opus:x64-windows-static aom:x64-windows-static
    • Linux/macOS: vcpkg install libvpx libyuv opus aom
  • run cargo run

Install vcpkg

git clone https://github.com/microsoft/vcpkg
cd vcpkg
git checkout 2023.04.15
cd ..
vcpkg/bootstrap-vcpkg.sh
export VCPKG_ROOT=$HOME/vcpkg

Build

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
git clone --recurse-submodules https://github.com/rustdesk/rustdesk
cd rustdesk
mkdir -p target/debug

How to build with Docker

Begin by cloning the repository and building the Docker container:

git clone https://github.com/rustdesk/rustdesk
cd rustdesk
git submodule update --init --recursive
docker build -t "rustdesk-builder" .

Then, each time you need to build the application, run the following command:

docker run --rm -it -v $PWD:/home/user/rustdesk -v rustdesk-git-cache:/home/user/.cargo/git -v rustdesk-registry-cache:/home/user/.cargo/registry -e PUID="$(id -u)" -e PGID="$(id -g)" rustdesk-builder

Note that the first build may take longer before dependencies are cached, subsequent builds will be faster. Additionally, if you need to specify different arguments to the build command, you may do so at the end of the command in the <OPTIONAL-ARGS> position. For instance, if you wanted to build an optimized release version, you would run the command above followed by --release. The resulting executable will be available in the target folder on your system, and can be run with:

target/debug/rustdesk

Or, if you're running a release executable:

target/release/rustdesk

Please ensure that you run these commands from the root of the RustDesk repository, or the application may not find the required resources. Also note that other cargo subcommands such as install or run are not currently supported via this method as they would install or run the program inside the container instead of the host.
