ControlMaster breaks commands

[denzuko]

Describe the bug
When using ControlMaster in $HOME/.ssh/config, soft serve only displays the menu and does not log anything from the client connection. Menu navigation does work but cannot execute info, repo create .., or like commands.

To Reproduce
Steps to reproduce the behavior:

1. setup a fresh soft serve server with go install ...
2. add the following to one's ~/.ssh/config:

Host softserve
        User admin
        Hostname localhost   # issue encountered both with & without this and the above. Adding for ease of testing (Host ... is arbitrary too)
       Port 23231
       ControlMaster     auto
       ControlPath       ~/.ssh/control-%C
       ControlPersist    yes

3. ssh softserve info

Expected behavior
Not to see menu view and that documented behavior works as intended

Environment (please complete the following information):

• OS: Alpine Linux 3.18.2
• OpenSSH_9.3p2, OpenSSL 3.1.2 1 Aug 2023
• Version v0.7.1

Hi @denzuko, Soft Serve doesn't support SSH ControlMaster. Soft Serve uses Golang SSH server which doesn't support ControlMaster, there is this open issue regarding adding support to ControlMaster in Golang crypto/ssh golang/go#32958
