I have a patch for decrypt_keyctl enabling it to work from an ssh session; how to submit?

I setup my hosts so that root is unencrypted, but swap, home, and some service specific directories are on encrypted partitions (mariadb, Nextcloud, burp, etc.). On reboot I ssh into the system, open the encrypted devices, mount the relevant devices, and start the services that depend on them (all scripted of course).

Something I struggled with for a long time (years) was that decrypt_keyctl doesn't work reliably or at all from an ssh session where I've su'd to root. Eventually, with much research, I was able to patch decrypt_keyctl to enable that scenario to work.

How can I contribute this modification to the decrypt_keyctl script?

Thanks,
Jonathan
