2017-05-25	virtio-9p/xen-9p: move 9p specific bits to core 9p code	Greg Kurz	1	-5/+1
	These bits aren't related to the transport so let's move them to the core code. Signed-off-by: Greg Kurz <groug@kaod.org> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org>
2017-05-16	xen: call qemu_set_cloexec instead of fcntl	Stefano Stabellini	1	-1/+1
	Use the common utility function, which contains checks on return values and first calls F_GETFD as recommended by POSIX.1-2001, instead of manually calling fcntl.

2017-04-25	xen/9pfs: send responses back to the frontend	Stefano Stabellini	1	-0/+19
	Once a request is completed, xen_9pfs_push_and_notify gets called. In xen_9pfs_push_and_notify, update the indexes (data has already been copied to the sg by the common code) and send a notification to the frontend. Schedule the bottom-half to check if we already have any other requests pending.

2017-04-25	xen/9pfs: implement in/out_iov_from_pdu and vmarshal/vunmarshal	Stefano Stabellini	1	-2/+97
	Implement xen_9pfs_init_in/out_iov_from_pdu and xen_9pfs_pdu_vmarshal/vunmarshall by creating new sg pointing to the data on the ring. This is safe as we only handle one request per ring at any given time.

2017-04-25	xen/9pfs: receive requests from the frontend	Stefano Stabellini	1	-0/+50
	Upon receiving an event channel notification from the frontend, schedule the bottom half. From the bottom half, read one request from the ring, create a pdu and call pdu_submit to handle it. For now, only handle one request per ring at a time.

2017-04-25	xen/9pfs: connect to the frontend	Stefano Stabellini	1	-1/+181
	Write the limits of the backend to xenstore. Connect to the frontend. Upon connection, allocate the rings according to the protocol specification. Initialize a QEMUBH to schedule work upon receiving an event channel notification from the frontend.

2017-04-25	xen/9pfs: introduce Xen 9pfs backend	Stefano Stabellini	1	-0/+96
	Introduce the Xen 9pfs backend: add struct XenDevOps to register as a Xen backend and add struct V9fsTransport to register as v9fs transport. All functions are empty stubs for now.
