This patch series adds more test case issuing ioctls to ucontrol VMs and its floating interrupt controller. The test cases trigger three possible null pointer dereferences within the handling of the KVM_DEV_FLIC_APF_ENABLE, KVM_DEV_FLIC_APF_DISABLE_WAIT and KVM_SET_GSI_ROUTING ioctl.
All of these issues do only exist on ucontrol VMs. Fixes for the issues are included within the patch series.
Whole series: Reviewed-by: Claudio Imbrenda imbrenda@linux.ibm.com
v2:
- added documentation changes
- simplify uc_flic_attrs; remove .getrc and .setrc from uc_flic_attrs
