On systems with UEFI Secure Boot enabled, recent Linux kernels will only load signed modules, so it's about time DKMS grew the capability to sign modules it's building.

These scripts are extended and scriptified variants of https://computerlinguist.org/make-dkms-sign-kernel-modules-for-secure-boot-on-ubuntu-1604.html and https://askubuntu.com/questions/760671/could-not-load-vboxdrv-after-upgrade-to-ubuntu-16-04-and-i-want-to-keep-secur/768310#768310 and add some error checking, a passphrase around your signing key, and support for compressed modules.

dkms-sign-module is a wrapper for the more generic sign-modules which can also be used outside of DKMS.

Installation

1. Create a directory under /root, say /root/module-signing, put the three scripts below in there and make them executable: chmod u+x one-time-setup sign-modules dkms-sign-module

RDMA verification
This work assumes there are two nodes to run iscsi target/initiator environment.

Load the RDMA drivers using the following command line
/etc/init.d/openibd start

If one is using the InfiniBand transport and he doesn't have a managed switch in the subnet, he has to start the Subnet Manager (SM). Doing this in one of the machines in the subnet is enough, this can be done with the following command line
/etc/init.d/opensmd start
