Description of problem:
When using mokutil to import a new certificate, it calculates the wrong size for the cert. According to the UEFI spec, it should be:
"...16 (size of the SignatureOwner component) + the size of the certificate itself."
However, mokutil is calculating this as:
CertList->SignatureSize = sizes[i] + sizeof(EFI_SIGNATURE_DATA) +
The sizeof(EFI_SIGNATURE_DATA) there is not necessary. This happens to throw the kernel into a fit and it fails to parse certs stored in MokListRT.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. import a cert with mokutil
2. reboot and do the MokManager thing
3. watch the kernel hate the result.
cert imported with wrong size in the efi_signature_list structure.
I've sent a patch to Peter and Matthew, and a pull request upstream for mokutil to fix this.
Proposing as F18 Blocker.
Discussed at 2012-12-12 blocker review meeting: http://meetbot.fedoraproject.org/fedora-bugzappers/2012-12-12/f18final-blocker-review-4.2012-12-12-17.01.log.txt . Rejected as a blocker on the understanding this only affects generation/installation of personal signatures, not use of the MS key. Accepted as NTH - pjones thinks it could go in as 0-day but isn't 100% sure and thinks it's safer to take it now, and the fix is isolated and only affects SB stuff, can't break anything else.

You mean like the big long comment and +1 karma I left in the update that is linked to in comment #4?
Sure. It fixes the issue.
Sorry, I overlooked that. Thanks.
