2014-09-22block: delete cow block driverStefan Hajnoczi1-1/+1
This patch removes support for the cow file format. Normally we do not break backwards compatibility but in this case there is no impact and it is the most logical option. Extraordinary claims require extraordinary evidence so I will show why removing the cow block driver is the right thing to do. The cow file format is the disk image format for Usermode Linux, a way of running a Linux system in userspace. The performance of UML was never great and it was hacky, but it enjoyed some popularity before hardware virtualization support became mainstream. QEMU's block/cow.c is supposed to read this image file format. Unfortunately the file format was underspecified: 1. Earlier Linux versions used the MAXPATHLEN constant for the backing filename field. The value of MAXPATHLEN can change, so Linux switched to a 4096 literal but QEMU has a 1024 literal. 2. Padding was not used on the header struct (both in the Linux kernel and in QEMU) so the struct layout varied across architectures. In particular, i386 and x86_64 were different due to int64_t alignment differences. Linux now uses __attribute__((packed)), QEMU does not. Therefore: 1. QEMU cow images do not conform to the Linux cow image file format. 2. cow images cannot be shared between different host architectures. This means QEMU cow images are useless and QEMU has not had bug reports from users actually hitting these issues. Let's get rid of this thing, it serves no purpose and no one will be affected.

2014-09-17ui/vnc: set TCP_NODELAYPeter Lieven1-0/+1
we currently have the Nagle algorithm enabled for all outgoing VNC updates. This may delay sensitive updates as mouse movements or typing in the console. As we currently prepare all data in a buffer and then send as much as we can disabling the Nagle algorithm should not cause big trouble. Well established VNC servers like TightVNC set TCP_NODELAY as well. A regular framebuffer update request generates exactly one framebuffer update which should be pushed out as fast as possible.

2014-09-05console: stop using PixelFormatGerd Hoffmann2-25/+13
With this patch the qemu console core stops using PixelFormat and pixman format codes side-by-side, pixman format code is the primary way to specify the DisplaySurface format: * DisplaySurface stops carrying a PixelFormat field. * qemu_create_displaysurface_from() expects a pixman format now. Functions to convert PixelFormat to pixman_format_code_t (and back) exist for those who still use PixelFormat. As PixelFormat allows easy access to masks and shifts it will probably continue to exist. [ xenfb added by Benjamin Herrenschmidt ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2014-09-05spice: make sure we don't overflow ssd->bufGerd Hoffmann1-5/+15
Related spice-only bug. We have a fixed 16 MB buffer here, being presented to the spice-server as qxl video memory in case spice is used with a non-qxl card. It's also used with qxl in vga mode. When using display resolutions requiring more than 16 MB of memory we are going to overflow that buffer. In theory the guest can write, indirectly via spice-server. The spice-server clears the memory after setting a new video mode though, triggering a segfault in the overflow case, so qemu crashes before the guest has a chance to do something evil. Fix that by switching to dynamic allocation for the buffer.

2014-07-11ui/gtk: Restore keyboard focus after Page changeJohn Snow1-3/+6
(Resending for correct email addresses via MAINTAINERS ...) In the GTK UI, after changing focus to the qemu monitor Notebook Page, when restoring focus to the virtual machine page, the keyboard focus is lost to a hidden GTK widget. Focus can only be restored to the virtual machine by pressing "tab" or any of the four directional arrow keys. Clicking in the window or grabbing/ungrabbing input does not restore keyboard focus to the child widget. This patch adjusts the Notebook page switching callback to automatically steal keyboard focus on the Page switch event, so that keyboard input does not appear to break or disappear after tabbing to the QEMU monitor.

2014-07-01ui/vnc: fix potential memory corruption issuesPeter Lieven2-86/+77
this patch makes the VNC server work correctly if the server surface and the guest surface have different sizes. Basically the server surface is adjusted to not exceed VNC_MAX_WIDTH x VNC_MAX_HEIGHT and additionally the width is rounded up to multiple of VNC_DIRTY_PIXELS_PER_BIT. If we have a resolution whose width is not dividable by VNC_DIRTY_PIXELS_PER_BIT we now get a small black bar on the right of the screen. If the surface is too big to fit the limits only the upper left area is shown. On top of that this fixes 2 memory corruption issues: The first was actually discovered during playing around with a Windows 7 vServer. During resolution change in Windows 7 it happens sometimes that Windows changes to an intermediate resolution where server_stride % cmp_bytes != 0 (in vnc_refresh_server_surface). This happens only if width % VNC_DIRTY_PIXELS_PER_BIT != 0. The second is a theoretical issue, but is maybe exploitable by the guest. If for some reason the guest surface size is bigger than VNC_MAX_WIDTH x VNC_MAX_HEIGHT we end up in severe corruption since this limit is nowhere enforced.

2014-07-01ui/vnc: limit client_cut_text msg payload sizePeter Lieven1-3/+10
currently a malicious client could define a payload size of 2^32 - 1 bytes and send up to that size of data to the vnc server. The server would allocated that amount of memory which could easily create an out of memory condition. This patch limits the payload size to 1MB max. Please note that client_cut_text messages are currently silently ignored. Signed-off-by: Peter Lieven <pl@kamp.de> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2014-06-29ui/cocoa: Fix handling of absolute positioning devicesPeter Maydell1-29/+46
Fix handling of absolute positioning devices, which were basically unusable for two separate reasons: (1) as soon as you pressed the left mouse button we would call CGAssociateMouseAndMouseCursorPosition(FALSE), which means that the absolute coordinates of the mouse events are never updated (2) we didn't account for MacOSX coordinate origin being bottom left rather than top right, and so all the Y values sent to the guest were inverted We fix (1) by aligning our behaviour with the SDL UI backend for absolute devices: * when the mouse moves into the window we do a grab (which means hiding the host cursor and sending special keys to the guest) * when the mouse moves out of the window we un-grab and fix (2) by doing the correct transformation in the call to qemu_input_queue_abs().
