Li Fei1 94a980c923 hv: hypercall: prevent sos can touch hv/pre-launched VM resource ... Current implementation, SOS may allocate the memory region belonging to hypervisor/pre-launched VM to a post-launched VM. Because it only verifies the start address rather than the entire memory region. This patch verifies the validity of the entire memory region before allocating to a post-launched VM so that the specified memory can only be allocated to a post-launched VM if the entire memory region is mapped in SOS’s EPT.
