sudobless

Let root grant a passwordless sudo session to a non-root shell. The user of the target shell must be in sudoers.

Usage

sudobless <pid of shell>

User terminal	Root terminal
User fails to sudo and checks the shell pid: `user@host:~$ sudo -i [sudo] password for user: ^C user@host:~$ echo $$ 96683 user@host:~$`

	Root blesses user with the shell pid: `root@host:~# sudobless 96683 root@host:~#`

User can now sudo without a password prompt: `user@host:~$ sudo -i root@host:~#`

Python 3 required

install -T -m744 -o root -g root sudobless.py /usr/local/bin/sudobless

Use at your own risk. If you mess something up, run sudo -K as the user you blessed to wipe all the sudo sessions.
This is tested on Arch Linux (kernel 5.5) x86_64 with sudo >= 1.8.22. It might not run on non-Linux
The python is draft quality but it should be easy to read / audit
