QEMU virtio_balloon decreases the memory usage of VM depends on the
cooperation of the guest kernel. If the guest kernel cheats with
the virtio_balloon, it can break the limit.
[1] is a Linux kernel with a cheat code.
This is an example in a VM with 1G memory 1CPU that use this kernel:
// Start VM.
// In the guest, use usemem(https://git.kernel.org/pub/scm/linux/kernel/git/wfg/vm-scalability.git)
// allocate 800M memory then the usage of VM will increase.
usemem 800m
// Check anon memory usage of QEMU in the host.

// The memory usage of QEMU increase back without deflation the balloon.

This commit tries to handle the issue.
It set the address of balloon pages to cannot access with mprotect
when inflating the balloon and set it back when deflating the balloon.
When guest kernel cheat code tries to access the pages inside the balloon,
the host kernel will call handle_ept_violation-> tdp_page_fault to handle it.
tdp_page_fault will call hva_to_pfn to get PFN of the page.
hva_to_pfn_fast and hva_to_pfn_slow will check the VMA access permission.
Then change the VMA access permission can handle the issue.
This is an example in a VM with 1G memory 1CPU that use this kernel:
// Start VM.
// In the guest, use usemem(https://git.kernel.org/pub/scm/linux/kernel/git/wfg/vm-scalability.git)
// allocate 800M memory then the usage of VM will increase.
usemem 800m
// Connect to the monitor of QEMU and inflate the balloon 800M.

This shows that the access is refused and QEMU stops.

Yes, and doing random mprotects() in virtio-balloon code is wrong on
many levels.
E.g., just do a guest memory dump using HMP/QMP and crash your VM. But
there is a lot more ... #VMAs, guest kdump, double kexec, ...
In summary: Bad idea,
