Fedora kernels are configured to drive in "permissive" mode, e.g. $ grep CONFIG_MODULE_SIG_FORCE /boot/config-4.0.3-202.fc21.x86_64 # CONFIG_MODULE_SIG_FORCE is not set therefore, properly signed *and* unsigned modules are loadable, e.g. - unsigned: $ modinfo vboxdrv filename: /lib/modules/4.0.3-202.fc21.x86_64/extra/vboxdrv.ko version: 4.3.28 (0x001a000a) license: GPL description: Oracle VM VirtualBox Support Driver author: Oracle Corporation srcversion: CB0F241526E12BE494014CF depends: vermagic: 4.0.3-202.fc21.x86_64 SMP mod_unload parm: force_async_tsc:force the asynchronous TSC mode (int) # sign-file -v sha256 signing_key.priv signing_key.x509 /lib/modules/4.0.3-202.fc21.x86_64/extra/vboxdrv.ko Size of unsigned module: 490384 Size of signer's name : 25 Size of key identifier : 20 Size of signature : 514 Size of information : 12 Size of magic number : 28 Signer's name : 'Fedora kernel signing key' Digest : sha256 - properly signed: $ modinfo vboxdrv filename: /lib/modules/4.0.3-202.fc21.x86_64/extra/vboxdrv.ko version: 4.3.28 (0x001a000a) license: GPL description: Oracle VM VirtualBox Support Driver author: Oracle Corporation srcversion: CB0F241526E12BE494014CF depends: vermagic: 4.0.3-202.fc21.x86_64 SMP mod_unload signer: Fedora kernel signing key sig_key: 95:7D:C8:E5:9F:5D:E6:03:71:49:1A:D0:9A:C6:8F:85:16:6C:B3:94 sig_hashalgo: sha256 parm: force_async_tsc:force the asynchronous TSC mode (int) $ dmesg -t | grep -i X.*509 Asymmetric key parser 'x509' registered Loading compiled-in X.509 certificates Loaded X.509 cert 'Fedora kernel signing key: 957dc8e59f5de60371491ad09ac68f85166cb394' Ref. https://www.kernel.org/doc/Documentation/module-signing.txt ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ VBox-users-community mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/vbox-users-community _______________________________________________ Unsubscribe: mailto:[email protected]?subject=unsubscribe
