From: "Dr. David Alan Gilbert" <dgilb...@redhat.com>
Hi,
This is the 1st set for the virtiofsd - a daemon
that implements the user space side of virtiofs.
The kernel and qemu device parts recently went in,
so the daemon is the only thing missing to have a working
set.
This set is the absolute minimal base set of patches;
it's not yet safe to use (from security or correctness);
I'll follow up with ~3 more series in the next few days
with:
a) Security patches that add sandboxing and checking
compared with normal fuse - that makes it safe.
b) Performance improvements including threading
c) Other fixes, including correctness.
but, this is a good start and gets things rolling.
The set pulls in a big chunk of the upstream libfuse library
(unmodified so that it's easy to check it really is upstream),
chops all the stuff out we don't need and then adds the
new transport we need.
For new files I've formatted the code according to qemu
standards; for files that are from upstream libfuse
I've kept with their standards for ease of future updating.
We can't just link with libfuse, since we have to make ABI incompatible
changes for the new transport.
Running this daemon is typically done with:
./virtiofsd -o vhost_user_socket=/path/socket -o source=/path/to/fs
connected to a qemu that's then started with:
-chardev socket,id=char0,path=/path/socket -device
vhost-user-fs-pci,queue-size=1024,chardev=char0,tag=myfs
and then in the guest mount with:
mount -t virtiofs myfs /mnt
