hash: 775dc7dba7afe2674dc0ef84e00bb773495d4c98
|
||||
body: >
|
||||
After moving to hashes for authenticating the allowed OS list, we need
|
||||
|
||||
to update the db variable on each HUP to make sure the new OS
|
||||
|
||||
will be bootable. After confirming that the update went through,
|
||||
|
||||
we need to update the dbx variable to make sure the old OS is
|
||||
|
||||
no longer bootable.

body: >
|
||||
In order to use hashes we can not use UEFI time-based authentication
|
||||
|
||||
for updates as this would prevent rollbacks. Instead we ship appendable
|
||||
|
||||
updates for both db and dbx that HUP can use.

- subject: Use hashes instead of certificates for secure boot image validation

hash: c205b247c14cbdd132cb1bb335da2d17fa40caf5
|

body: >
|

This patch changes the validation of bootable images from certificate
|
||||
|
||||
signatures to a list of allowed hashes of binaries. This only applies
|
||||
|
||||
on db level, PK and KEK are still certificates.
|
||||
|
||||
|
||||
The motivation is that certificates expire and we need to be sure
|
||||
|
||||
that even devices that have been lying on a shelf for several years
|
||||
|
||||
or whose CMOS battery has died and reset date to 1970-01-01 are still
|
||||
|
||||
bootable. Using hashes is more aligned with this use-case and also
|
||||
|
||||
more similar to the approach that embedded SoCs use.
