Since kernel version 4.4.0-20, it was enforced that unsigned kernel modules will not be allowed to run with Secure Boot enabled. Because you want to keep Secure Boot, then the next logical step is to sign those modules.

So let's try it.

Create signing keys

openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -days 36500 -subj "/CN=Descriptive name/"

• Find files containing "foo", and print the line matches in context: ag foo
• Find files containing "foo" in a specific directory: ag foo path/to/directory
• Find files containing "foo", but only list the filenames: ag -l foo
• Find files containing "FOO" case-insensitively, and print only the match, rather than the whole line: ag -i -o FOO
• Find "foo" in files with a name matching "bar": ag foo -G bar

Creating the GIT Patch

The following command creates a single .patch file that contains multiple commits.

git format-patch cc1dde0dd^..6de6d4b06 --stdout > foo.patch

You can then apply it like so:

git am foo.patch
Note: Be sure to use ^.. instead of .. if you want the first commit SHA to be included.
