モジュールを作成して使用しましたmake modules_install。
次のコマンドを実行しました。この点:
openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -subj "/CN=Owner/"
mokutil --import MOK.der
その後、起動時にMokManagerを使用してmokを再起動して登録しました。再起動後、次のコマンドを使用してファイルに署名しました（要点も少し変更されました）。
sudo /lib/modules/$(uname -r)/build/scripts/sign-file sha256 ./MOK.priv ./MOK.der /lib/modules/$(uname -r)/extra/veikk.ko
modinfo veikk以下は、役に立つことができる、とのmokutil -l出力です。sudo cat /proc/keys

建物/署名はどちらもエラーは発生しません。キーはMokManagerによってロードされたようです（キー3を参照mokutil -l）。これをどのように解釈するのかはよくわかりませんが、/proc/keys危険の兆候がある場合に備えて組み込みました。ただし、実際にモジュールをロードしようとすると、エラーが発生します。
$ sudo modprobe veikk
modprobe: ERROR: could not insert 'veikk': Required key not available
なぜこれが起こるのですか？
役に立つ場合は、Arch Linux（カーネル5.1.5）を実行しており、セキュアブートが機能するようにshimとmokmanagerをインストールしてカーネル設定を使用してくださいmodule.sig_enforce=1。 （セキュアブートが無効になっていると、モジュール署名は機能しますが、セキュアブートが有効になっている間に他の人がモジュールに署名するのを助けようとしています。）
編集する：キーを生成するときにエラーが発生したことに気づきました。
openssl req -new -x509 -newkey rsa:2048 -keyout MOK.priv -outform DER -out MOK.der -nodes -subj "/CN=Owner/"
引数は1つでなければならず-days、そうでなければ0です（mokutils -l出力を参照）。ただし、このコマンドは機能しません（ただし、有効な時間範囲を提供します）。
