 To remove the signature from the MLNX_OFED kernel modules:
# rpm -qa | grep -E "kernel-ib|mlnx-ofa_kernel" | xargs rpm -ql | grep "\.ko$" | xargs
strip -g
After the signature has been removed, a massage as the below will no longer be presented upon
module loading:
"Request for unknown module key 'Mellanox Technologies signing key:
61feb074fc7292f958419386ffdd9d5ca999e403' err -11"
However, please note that a similar message as the follwoing will still be presented:
"my_module: module verification failed: signature and/or required key missing - taint-
ing kernel"
This message is presented once, only for each boot for the first module that either has no signa-
ture or whose key is not in the kernel key ring. So it's much easier to miss this message. You
won't see it on repeated tests where you unload and reload a kernel module until you reboot.
There is no way to eliminate this message.
