2012-02-27usb: Resolve warnings about unassigned bus on usb device creationJan Kiszka9-34/+26
When creating an USB device the old way, there is no way to specify the target bus. Thus the warning issued by usb_create makes no sense and rather confuses our users. Resolve this by passing a bus reference to the usbdevice_init handler and letting those handlers forward it to usb_create.

2012-02-27slirp: Fix assertion failure on rejected DHCP requestsDavid Gibson1-1/+2
The guest network stack might DHCPREQUEST an address that the slirp built in dhcp server can't let it have - for example if the guest has an old leases file from another network configuration. In this case the dhcp server should and does reject the request and prepares to send a DHCPNAK to the client. However, in this case the daddr variable in bootp_reply() is set to 0.0.0.0. Shortly afterwards, it unconditionally attempts to pre-insert the new client address into the ARP table. This causes an assertion failure in arp_address_add() because of the 0.0.0.0 address. According to RFC2131, DHCPNAK messages for clients on the same subnet must be sent to the broadcast address (S3.2, subpoint 2).

2012-02-27slirp: Fix requeuing of batchq packets in if_startJan Kiszka1-16/+19
In case we requeued a packet that was the head of a longer session queue, we failed to restore this ordering. Also, we did not properly deal with changes to Slirp::next_m. Instead of a cumbersome roll back, this fix simply avoids any changes until we know if the packet was actually sent. Both fixes crashes due to inconsistent queues and simplifies the logic. Thanks to Zhi Yong Wu who found the reason for these crashes. CC: Zhi Yong Wu <wuzhy@linux.vnet.ibm.com> CC: Fabien Chouteau <chouteau@adacore.com> Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

2012-02-27usb-redir: Return USB_RET_NAK when we've no data for an interrupt endpointHans de Goede1-1/+4
We should return USB_RET_NAK, rather then a 0 sized packet, when we've no data for an interrupt IN endpoint. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-27usb-redir: Limit return values returned by iso packetsHans de Goede1-2/+2
The usbredir protocol uses a status of usb_redir_stall to indicate that an iso data stream has stopped (ie because the urbs failed on resubmit), but iso packets should never return a result of USB_RET_STALL, since iso endpoints cannot stall. So instead simply always return USB_RET_NAK on iso stream errors. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-27usb-redir: Let the usb-host know about our device filteringHans de Goede2-1/+21
libusbredirparser-0.3.4 adds 2 new packets which allows us to notify the usb-host: -about the usb device filter we have (if any), so that it knows not the even try to redirect certain devices -when we reject a device based on filtering (in case it tries anyways) Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-27usb-redir: Always clear device state on filter rejectHans de Goede1-4/+7

2012-02-27usb-ehci: Handle ISO packets failing with an error other then NAKHans de Goede1-3/+19
Before this patch the ehci code was not checking for any other errors other then USB_RET_NAK. This causes 2 problems: 1) Other errors are not reported to the guest. 2) When transactions with the ITD_XACT_IOC bit set completing with another error would not result in USBSTS_INT getting set. I hit this problem when unplugging devices while iso data was streaming from the device to the guest. When this happens it takes a while for the guest to process the unplugging and remove ISO transactions from the ehci schedule, in the mean time these transactions would complete with a result of USB_RET_NODEV, which was not handled. This lead to the Linux guest's usb subsystem "hanging", that is it would no longer see new usb devices getting plugged in and running for example lsusb would lead to a stuck (D state) lsusb process. This patch fixes this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Before commit ed5a83ddd8c1d8ec7b1015315530cf29949e7c48 each device provided it's own response to USB_REQ_GET_STATUS, but after it that response was based on bmAttributes, which was errounously set for usb-ccid as 0xa0 and not 0xe0.

2012-02-27usb-desc: fix user trigerrable segfaults (!config)Alon Levy1-3/+17
Check for dev->config being NULL in two places: USB_REQ_GET_CONFIGURATION and USB_REQ_GET_STATUS. The behavior of USB_REQ_GET_STATUS is unspecified in the Default state, that corresponds to dev->config being NULL (it defaults to NULL and is reset whenever a SET_CONFIGURATION with value 0, or attachment). I implemented it to correspond with the state before ed5a83ddd8c1d8ec7b1015315530cf29949e7c48, the commit moving SET_STATUS to usb-desc; if dev->config is not set we return whatever is in the first configuration. The behavior of USB_REQ_GET_CONFIGURATION is also undefined before any SET_CONFIGURATION, but here we just return 0 (same as specified for the Address state). A win7 guest failed to initialize the device before this patch, segfaulting when GET_STATUS was called with dev->config == NULL. With this patch the passthrough device still doesn't work but the failure is unrelated. Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-27usb-ehci: sanity-check iso xfersGerd Hoffmann1-6/+10

2012-02-24configure: Check whether makecontext() is a glibc stub functionPeter Maydell1-0/+4
On some systems (notably ARM Linux) glibc provides implementations of makecontext(), getcontext() and friends which are stubs which always return failure. Make the configure test for makecontext() also check for the presence of the __stub_makecontext macro which indicates the presence of these stubs, so we can avoid trying to use them and fall back to a different coroutine implementation instead.

Fix a bug (introduced in commit a0abe47) where a command line which specified no machine arguments (either explicitly or implicitly via -kernel &co) would result in a segfault because of a NULL pointer returned from qemu_opts_find(qemu_find_opts("machine"), 0).

2012-02-24Remove screendump dummy functions.Gerd Hoffmann3-12/+4

2012-02-24suspend: make serial ports wakeup the guest.Gerd Hoffmann1-0/+6
Add a 'wakeup' property to the serial port. It is off by default. When enabled any incoming character on the serial line will wake up the guest.

2012-02-24suspend: make ps/2 devices wakeup the guestGerd Hoffmann1-0/+6
This patch adds wakeup support to ps/2 emulation. Any key press on the ps/2 keyboard will wakeup the guest. Likewise any mouse button press will wakeup the guest. Mouse moves are ignored, so the guest will not wakeup in case your mouse crosses the vnc window of a suspended guest by accident.

2012-02-24suspend: switch acpi s3 to new infrastructure.Gerd Hoffmann10-42/+47
This patch switches pc s3 suspend over to the new infrastructure. The cmos_s3 qemu_irq is killed, the new notifier is used instead. The xen hack goes away with that too, the hypercall can simply be done in a notifier function now. This patch also makes the guest actually stay suspended instead of leaving suspend instantly, so it is useful for more than just testing whenever the suspend/resume cycle actually works.

2012-02-24suspend: add infrastructureGerd Hoffmann2-0/+76
This patch adds some infrastructure to handle suspend and resume to qemu. First there are two functions to switch state and second there is a suspend notifier: * qemu_system_suspend_request is supposed to be called when the guest asks for being be suspended, for example via ACPI. * qemu_system_wakeup_request is supposed to be called on events which should wake up the guest. * qemu_register_suspend_notifier can be used to register a notifier which will be called when the guest is suspended. Machine types and device models can hook in there to modify state if needed. * qemu_register_wakeup_notifier can be used to register a notifier which will be called when the guest is woken up. Machine types and device models can hook in there to modify state if needed. * qemu_system_wakeup_enable can be used to enable/disable wakeup events.

2012-02-24acpi: add ACPIREGSGerd Hoffmann4-143/+145
All those acpi structs are not independent from each other.
