Title:
  impish/linux-gcp: CONFIG_BPF_UNPRIV_DEFAULT_OFF must be set to y

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Impish:
  Fix Released

Bug description:
  This option will disable uprivileged BPF by default. It can be reenabled, though, as it uses the new value 2 for the kernel.unprivileged_bpf_disabled sysctl. That value disables it, but allows the sysctl knob to be set back to 0.
      
  This allows sysadmins to enable unprivileged BPF back by using sysctl config files.

  All the other impish kernels have this option enabled, but linux-gcp
  still has this disabled. Make sure to re-align with the other impish
  kernels.
