Added verifiers-Fix-compressed-kernel-verification-failed.patch, #53493 |
This patch creates a problem for other verifiers. Both technical and security. Technical is that other verifiers use file contents before applying any transformation. The security problem is that compressors are not verified to be secure, they are large and complex. If EFI needs a special order it's better to have it as a separate filter.
