Subject: [PATCH] 01fips: run sha512hmac from directory HMAC file directory
|
|
|
fab351 |
|
|
|
fab351 |
That way, the HMAC file can contain a relative path instead of an
|
|
|
fab351 |
absolute one. The issue is that right now the kernel RPM bakes the
|
|
|
fab351 |
`/boot/vmlinuz-${kver}` path into the HMAC file which poses an issue for
|
|
|
fab351 |
rpm-ostree systems (and any other system where the kernel isn't simply
|
|
|
fab351 |
in the top-level `/boot`.
|
|
|
fab351 |
|
|
|
fab351 |
For now, we're hacking around this in rpm-ostree:

|

https://github.com/coreos/rpm-ostree/pull/1934
|
|
|
fab351 |
|
|
|

Though I'd like to propose the same change in the kernel spec file.
