kernel 4.14.15 and vboxconfig

[Didier]

Hi,

vboxconfig fails with new kernel 4.14.15

Message is:

T470 kernel: vboxdrv: version magic '4.14.15-300.fc27.x86_64 SMP mod_unload ' should be '4.14.15-300.fc27.x86_64 SMP mod_unload retpoline '

No problem with previous kernel 4.14.14

See: ​https://bugzilla.redhat.com/show_bug.cgi?id=1539165

Fixed by kernel-4.14.15-301.fc27.x86_64

Something to consider, I backed out the patch that was enforcement, but what was really happening is it was refusing to load any module that was built with a non retpoline capable compiler (gcc builds 7.2.1-7 and 7.3.1-1 in Fedora have retpoline support). So currently, your modules load, but you are exposed for spectre variant 2 through those modules. Probably not a huge concern, but you may consider installing gcc-7.3.1-1 from koji ​https://koji.fedoraproject.org/koji/buildinfo?buildID=1020649 and rebuilding the modules just to be covered. It should be filed as an update soon.
