Hi all,
This patch series implements a new transport for 9pfs, aimed at Xen
systems.
The transport is based on a traditional Xen frontend and backend drivers
pair. This patch series implements the backend, which typically runs in
Dom0. I sent another series to implement the frontend in Linux
(http://marc.info/?l=linux-kernel&m=148883047125960&w=2).
The backend complies to the Xen transport for 9pfs specification
version 1, available here:
http://xenbits.xen.org/gitweb/?p=xen.git;a=blob_plain;f=docs/misc/9pfs.markdown;hb=HEAD
Changes in v3:
- do not build backends for targets that do not support xen
- remove xen_9pfs.h, merge its content into xen-9p-backend.c
- remove xen_9pfs_header, introduce P9MsgHeader
- use le32_to_cpu to access P9MsgHeader fields
- many coding style fixes
- run checkpatch on all patches
- add check if num_rings < 1
- use g_strdup_printf
- free fsdev_id in xen_9pfs_free
- add comments
Changes in v2:
- fix coding style
- compile xen-9p-backend.c if CONFIG_XEN_BACKEND
- add patch to set CONFIG_XEN_BACKEND only for the right targets
- add review-bys
Stefano Stabellini (9):
xen: do not build backends for targets that do not support xen
xen: import ring.h from xen
9p: introduce a type for the 9p header
xen/9pfs: introduce Xen 9pfs backend
xen/9pfs: connect to the frontend
xen/9pfs: receive requests from the frontend
xen/9pfs: implement in/out_iov_from_pdu and vmarshal/vunmarshal
xen/9pfs: send responses back to the frontend
xen/9pfs: build and register Xen 9pfs backend
