2011-07-18virtio-console: Prevent abort()s in case of host chardev closeAmit Shah1-1/+15
A host chardev could close just before the guest sends some data to be written. This will cause an -EPIPE error. This shouldn't be propagated to virtio-serial-bus. Ideally we should close the port once -EPIPE is received, but since the chardev interface doesn't return such meaningful values to its users, all we get is -1 for any kind of error. Just return 0 for now and wait for chardevs to return better error messages to act better on the return messages. Signed-off-by: Amit Shah <amit.shah@redhat.com>

2011-07-17vhost: fix double free on device stopMichael S. Tsirkin1-0/+1
vhost dev stop failed to clear the log field. Typically not an issue as dev start overwrites this field, but if logging gets disabled before the following start, it doesn't so this causes a double free. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-07-17xen_console: fall back to qemu serial deviceAlexander Graf1-4/+7
The new xen_console protocol changed the default xen_console output device from whatever Qemu chose to whatever xenstore choses and "pty" as fallback. This is not how Qemu works. It has its own serial redirection semantics. So it xenstore doesn't contain information on what to do, Qemu is the place to ask. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-07-17xen_console: support the new extended xenstore protocolStefano Stabellini3-6/+23
Since CS 21994 on xen-unstable.hg and CS 466608f3a32e1f9808acdf832a5843af37e5fcec on qemu-xen-unstable.git, few changes have been introduced to the PV console xenstore protocol, as described by the document docs/misc/console.txt under xen-unstable.hg. From the Qemu point of view, very few modifications are needed to correctly support the protocol: read from xenstore the "output" node that tell us what the output of the PV console is going to be. In case the output is a tty, write to xenstore the device name. Changes in v2: - fix error paths: free malloc'ed strings and close the xenstore connection before returning; - remove useless snprintf in xenstore_store_pv_console_info if i == 0. Changes in v3: - replace xs_daemon_open/xs_daemon_close with xs_open/xs_close. Changes in v4: - add a compatibility implementation of xs_open/xs_close. Changes in v5: - fix code style.

2011-07-17xen_disk: treat "aio" as "raw"Stefano Stabellini1-0/+3

2011-07-17xen_disk: cope with missing xenstore "params" nodeStefano Stabellini1-7/+27
When disk is a cdrom and the drive is empty the "params" node in xenstore might be missing completely: cope with it instead of segfaulting. Updated in v2: - actually removed the strchr(blkdev->params, ':') that caused the segfault; - free all the allocated strings from xenstore before returning; Updated in v3: - set blkdev fields to NULL after free'ing them.

2011-07-17xen: add vkbd support for PV on HVM guestsStefano Stabellini1-7/+12
Register the vkbd backend even when running as device emulator for HVM guests: it is useful because it doesn't need a frequent timer like usb. Check whether the XenInput DisplayState has been set in the initialise state, rather than the input state. In case the DisplayState hasn't been set and there is no vfb for this domain, then set the XenInput DisplayState to the default one.

2011-07-17xen: Fold CONFIG_XEN_MAPCACHE into CONFIG_XENJan Kiszka1-9/+0
Xen won't be enabled if there is no backend support available for the host. And that also means the map cache will work.

2011-07-12esp: cancel current request only if some request is in flightHervé Poussineau1-1/+1
This bug was introduced in 94d3f98a3f3caddd7875f9a11776daeb84962a7b: scsi_cancel_io was checking if some request was pending before trying to cancel it, while scsi_req_cancel always cancels the request. This may lead to a crash of Qemu due to dereferencing a NULL pointer, as exhibited by NetBSD 5.1 installer on MIPS Magnum emulation.

2011-07-05usb: assert on calling usb_attach(port, NULL) on a port without a devHans de Goede1-5/+4
with the "usb-ehci: cleanup port reset handling" patch in place no callers are calling usb_attach(port, NULL) for a port where port->dev is NULL. Doing that makes no sense as that causes the port detach op to get called for a port with nothing attached. Add an assert that port->dev != NULL when dev == NULL, and remove the check for not having a port->dev in the dev == NULL case.

2011-07-05usb: Replace device_destroy bus op with a child_detach port opHans de Goede8-29/+69
Note this fixes 2 things in one go, first of all the device_destroy bus op should be a device_detach bus op, as pending async packets from the device should be cancelled on detach not on destroy. Secondly having this as a bus op won't work with companion controllers, since then there will be 1 bus driven by the ehci controller and thus 1 set of bus ops, but the device being detached may be downstream of a handed over port. Making the detach of a downstream device a port op allows the ehci controller to forward this to the companion controller port for handed over ports.

2011-07-05usb: Make port wakeup and complete ops take a USBPort instead of a DeviceHans de Goede7-26/+28
This makes them consistent with the attach and detach ops, and in general it makes sense to make portops take a port as argument. This also makes adding support for a companion controller easier / cleaner.
