Hi all, this series introduces the frontend for the newly introduced PV Calls procotol.
PV Calls is a paravirtualized protocol that allows the implementation of a set of POSIX functions in a different domain. The PV Calls frontend sends POSIX function calls to the backend, which implements them and returns a value to the frontend and acts on the function call. For more information about PV Calls, please read: https://xenbits.xen.org/docs/unstable/misc/pvcalls.html This patch series only implements the frontend driver. It doesn't attempt to redirect POSIX calls to it. The functions exported in pvcalls-front.h are meant to be used for that. A separate patch series will be sent to use them and hook them into the system. Changes in v7: - define sock_mapping earlier - make sure that every patch in the series builds - call pvcalls_front_free_map(map->passive.accept_map) without the socket_lock - remove now unused bool lock parameter to pvcalls_front_free_map - XEN_PVCALLS_FRONTEND: default n and select XEN_XENBUS_FRONTEND Stefano Stabellini (13): xen/pvcalls: introduce the pvcalls xenbus frontend xen/pvcalls: implement frontend disconnect xen/pvcalls: connect to the backend xen/pvcalls: implement socket command and handle events xen/pvcalls: implement connect command xen/pvcalls: implement bind command xen/pvcalls: implement listen command xen/pvcalls: implement accept command xen/pvcalls: implement sendmsg xen/pvcalls: implement recvmsg xen/pvcalls: implement poll command xen/pvcalls: implement release command xen: introduce a Kconfig option to enable the pvcalls frontend drivers/xen/Kconfig | 11 + drivers/xen/Makefile | 1 + drivers/xen/pvcalls-front.c | 1271 +++++++++++++++++++++++++++++++++++++++++++ drivers/xen/pvcalls-front.h | 28 + 4 files changed, 1311 insertions(+) create mode 100644 drivers/xen/pvcalls-front.c create mode 100644 drivers/xen/pvcalls-front.h _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
