Given secure boot enabled, for kernel <= 6.2.0 we have > cat /sys/kernel/security/lockdown [none] integrity confidentiality while for kernel 6.2.1 > cat /sys/kernel/security/lockdown none [integrity] confidentiality Bug or feature? As for the latter, I don't see any hint in the changelog of 6.2.1: https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.1 Any idea? Thx.
