trace-events: fix code style: %# -> 0x% In trace format '#' flag of printf is forbidden. Fix it to '0x%'. This patch is created by the following: check that we have a problem > find . -name trace-events | xargs grep '%#' | wc -l 56 check that there are no cases with additional printf flags before '#' > find . -name trace-events | xargs grep "%[-+ 0'I]+#" | wc -l 0 check that there are no wrong usage of '#' and '0x' together > find . -name trace-events | xargs grep '0x%#' | wc -l 0 fix the problem > find . -name trace-events | xargs sed -i 's/%#/0x%/g' [Eric Blake noted that xargs grep '%[-+ 0'I]+#' should be xargs grep "%[-+ 0'I]+#" instead so the shell quoting is correct. --Stefan] Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-id: 20170731160135.12101-3-vsementsov@virtuozzo.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

xen: use libxendevice model to restrict operations This patch adds a command-line option (-xen-domid-restrict) which will use the new libxendevicemodel API to restrict devicemodel [1] operations to the specified domid. (Such operations are not applicable to the xenpv machine type). This patch also adds a tracepoint to allow successful enabling of the restriction to be monitored. [1] I.e. operations issued by libxendevicemodel. Operation issued by other xen libraries (e.g. libxenforeignmemory) are currently still unrestricted but this will be rectified by subsequent patches.

xen: introduce new 'XenBus' and 'XenDevice' object hierarchy This patch adds the basic boilerplate for a 'XenBus' object that will act as a parent to 'XenDevice' PV backends. A new 'XenBridge' object is also added to connect XenBus to the system bus. The XenBus object is instantiated by a new xen_bus_init() function called from the same sites as the legacy xen_be_init() function. Subsequent patches will flesh-out the functionality of these objects.

xen: create xenstore areas for XenDevice-s This patch adds a new source module, xen-bus-helper.c, which builds on basic libxenstore primitives to provide functions to create (setting permissions appropriately) and destroy xenstore areas, and functions to 'printf' and 'scanf' nodes therein. The main xen-bus code then uses these primitives [1] to initialize and destroy the frontend and backend areas for a XenDevice during realize and unrealize respectively. The 'xen-block' implementation is extended with a 'get_name' method that returns the VBD number. This number is required to 'name' the xenstore areas. NOTE: An exit handler is also added to make sure the xenstore areas are cleaned up if QEMU terminates without devices being unrealized. [1] The 'scanf' functions are actually not yet needed, but they will be needed by code delivered in subsequent patches.
