61e34331c2 virtio-fs: validate request len in fs_slave_io()
We made sure gpa is in cache range, but not the end addr of request,
which is (gpa + len). If the end addr of request is beyond dax cache
window, vmm would corrupt guest memory or crash.

Fix it by making sure end addr of request is within cache range as well.
And while we're at it, return EFAULT if the request is out of range, as
write(2)/read(2) returns EFAULT when buffer is outside accessible
address space.

c1e6d0022b ci: Add memory resizing use case to vhost-user tests
All vhost-user-blk, vhost-user-net and virtio-fs integration tests are
extended with memory resizing. The point is to validate that we can
hotplug some memory and keep these backends to work as expected.

Just a note that because memory resizing is not supported by mmio, we
limit these extensions to all non-mmio use cases.

This change introduces a new CLI option --seccomp. This allows the user
to enable/disable the seccomp filters when needed. Because the user now
has the possibility to disable the seccomp filters, and because the
Cloud-Hypervisor project wants to enforce the maximum security by
default, the seccomp filters are now applied by default.

18fbd303ab vhost-user-fs: return correct result of fs_slave_io()
Virtio-fs daemon expects fs_slave_io() returns the number of bytes

nothing has been read/written.

Fix it by returning the actual bytes read/written. Note that This

f7197e8415 vmm: Add a "discard_writes=" to --pmem
This opens the backing file read-only, makes the pages in the mmap()
read-only and also makes the KVM mapping read-only. The file is also
mapped with MAP_PRIVATE to make the changes local to this process only.

This is functional alternative to having support for making a
virtio-pmem device readonly. Unfortunately there is no concept of
readonly virtio-pmem (or any type of NVDIMM/PMEM) in the Linux kernel so
to be able to have a block device that is appears readonly in the guest
requires significant specification and kernel changes.
