2016-11-15vhost: migration blocker only if shared log is usedRafael David Tinoco1-1/+1
Commit 31190ed7 added a migration blocker in vhost_dev_init() to check if memfd would succeed. It is better if this blocker first checks if vhost backend requires shared log. This will avoid a situation where a blocker is added inappropriately (e.g. shared log allocation fails when vhost backend doesn't support it).

2016-11-15virtio-net: mark VIRTIO_NET_F_GSO as legacyMichael S. Tsirkin1-0/+1
virtio 1.0 spec says this is a legacy feature bit, hide it from guests in modern mode. Note: for cross-version migration compatibility, we keep the bit set in host_features. The result will be that a guest migrating cross-version will see host features change under it. As guests only seem to read it once, this should not be an issue.

2016-11-10hw/input/hid: support alternative sysrq/break scancodes for gtk-vncPeter Korsgaard1-2/+2
The printscreen/sysrq and pause/break keys currently don't work for guests using -usbdevice keyboard when accessed through vnc with a gtk-vnc based client. The reason for this is a mismatch between gtk-vnc and qemu in how these keys should be mapped to XT keycodes. On the original IBM XT these keys behaved differently than other keys. Quoting from https://www.win.tue.nl/~aeb/linux/kbd/scancodes-1.html: The keys PrtSc/SysRq and Pause/Break are special. The former produces scancode e0 2a e0 37 when no modifier key is pressed simultaneously, e0 37 together with Shift or Ctrl, but 54 together with (left or right) Alt. (And one gets the expected sequences upon release. But see below.) The latter produces scancode sequence e1 1d 45 e1 9d c5 when pressed (without modifier) and nothing at all upon release. However, together with (left or right) Ctrl, one gets e0 46 e0 c6, and again nothing at release. It does not repeat. Gtk-vnc supports the 'QEMU Extended Key Event Message' RFB extension to send raw XT keycodes directly to qemu, but the specification doesn't explicitly specify how to map such long/complicated keycode sequences. From the spec (https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#qemu-extended-key-event-message) The keycode is the XT keycode that produced the keysym. An XT keycode is an XT make scancode sequence encoded to fit in a single U32 quantity. Single byte XT scancodes with a byte value less than 0x7f are encoded as is. 2-byte XT scancodes whose first byte is 0xe0 and second byte is less than 0x7f are encoded with the high bit of the first byte set hid.c currently expects the keycode sequence with shift/ctl for sysrq (e0 37 -> 0xb7 in RFB), whereas gtk-vnc uses the sequence with alt (0x54). Likewise, hid.c expects the code without modifiers (e1 1d 45 -> 0xc5 in RFB), whereas gtk-vnc sends the keycode sequence with ctrl for pause (e0 46 -> 0xc6 in RFB). See keymaps.cvs in gtk-vnc for the mapping used: https://git.gnome.org/browse/gtk-vnc/tree/src/keymaps.csv#n150 Now, it isn't obvious to me which sequence is really "right", but as the 0x54/0xc6 keycodes are currently unused in hid.c, supporting both seems like the pragmatic solution to me. The USB HID keyboard boot protocol used by hid.c doesn't have any other mapping applicable to these keys. The other guest keyboard interfaces (ps/2, virtio, ..) are not affected, because they handle these keys differently.

2016-11-07hw/i2c/bitbang_i2c: Handle NACKs from devicesPeter Maydell1-4/+15
If the guest attempts to talk to a nonexistent device over i2c, the i2c_start_transfer() function will return non-zero, indicating that the bus is signalling a NACK. Similarly, if the i2c_send() function returns nonzero then the target device returned a NACK. Handle this possibility in the bitbang_i2c code, by returning the state machine to the STOPPED state and returning the NACK bit to the guest. This bit of missing functionality was spotted by Coverity (it noticed that we weren't checking the return value from i2c_start_transfer()).
