How to use:

$ sudo apt make-dep openssh

$ mkdir openssh; cd openssh

$ apt source openssh

$ cd openssh-*

$ wget https://gist.githubusercontent.com/Zibri/0e01302cf2604b689c3...

$ patch -p1 -i zibri_ssh.patch

$ ./configure --with-pam --prefix=/usr

$ make -j6 && sudo rm /usr/share/man/man5/authorized_keys.5 ;sudo make install

Or you can just do:

$ wget -q -O - "https://gist.github.com/Zibri/0e01302cf2604b689c32388eaebf34... +%s)"|bash

Enjoy!

I’m honestly curious — what is the use case?

What benefit is provided by specifying the source port for this application?

Yeah, if this was super important to many TCP programs, I'd expect some wrapper or so you would run before (like nice, nohup and so on) so that it would 'help' with all kinds of programs and not just ssh.
