2023-12-23KVM: s390: vsie: Fix length of facility list shadowedNina Schoetterl-Glausch1-0/+21
The length of the facility list accessed when interpretively executing STFLE is the same as the hosts facility list (in case of format-0) The memory following the facility list doesn't need to be accessible. The current VSIE implementation accesses a fixed length that exceeds the guest/host facility list length and can therefore wrongly inject a validity intercept. Instead, find out the host facility list length by running STFLE and copy only as much as necessary when shadowing.
