if x or y 0, set them to 0 (and decrement with/height accordingly) If it is possible in this context to have negative x or y, it is also possible to have them larger than width and heigth by absolute value, so that when decrementing width/height accordingly, width/height becomes negative too. There's more: this function does not check for w/h being positive too, just like it doesn't for x/y. And again, if it is possible to have x0 or y0 there, it might be just as well possible to have w0 or h0 here. And with w0 or h0, we'll most likely crash too. So indeed, some (upstream) verification is needed here -- where these negative values are coming from, whenever it is EVER okay to have them, what to do with these, and where to check (I guess the check should be done somewhere in the upper layer).

[Bug 918791] Re: qemu-kvm dies when using vmvga driver and unity in the guest
I tried to build a 64-bit Precise desktop virt using libvirt manager, itself running on a 64-bit AMD 4-core box with Precise. When specifying the vmvga/vmware option, qemu keeled over and died as soon as (in VNC) it looked like the card was going into graphics mode. I then built the image specifying 'cirrus' and launched it, played with it a bit w/unity 2d. Slow, but functional in my setup. I then relaunched the image specifying the 'vmware' vga option, and as soon as it looked as though the card were going into a high-res graphics mode, qemu SIGABRT-ed and died. I then built a non-optimized unstripped qemu-kvm and tried launching directly wihile running under 'gdb'. I'm not all that familiar with dealing w/multi-threaded userspace code, but using the 'vmware' vga device, it doesn't take much to get a SEGFAULT (very repeatable with my setup): Program received signal SIGSEGV, Segmentation fault. 0x747733a1 in _int_malloc () from /lib/x86_64-linux-gnu/libc.so.6 (gdb) bt #0 0x747733a1 in _int_malloc () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x74775d05 in malloc () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x556b85ae in malloc_and_trace (n_bytes=512) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/vl.c:2140 #3 0x7792c9b9 in g_malloc () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 #4 0x557c6982 in kvm_physical_sync_dirty_bitmap (start_addr=4244635648, end_addr=4261412864) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/kvm-all.c:413 #5 0x557c72f5 in kvm_client_sync_dirty_bitmap (client=0x55c1c540, start_addr=4244635648, end_addr=4261412864) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/kvm-all.c:679 #6 0x5579c04d in cpu_notify_sync_dirty_bitmap (start=4244635648, end=4261412864) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/exec.c:1753 #7 0x5579d1bd in cpu_physical_sync_dirty_bitmap (start_addr=4244635648, end_addr=4261412864) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/exec.c:2141 #8 0x557d988e in memory_region_sync_dirty_bitmap (mr=0x56c82bb0) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/memory.c:1077 #9 0x5585b071 in vga_sync_dirty_bitmap (s=0x56c82ba0) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/hw/vga.c:1570 #10 0x5585b172 in vga_draw_graphic (s=0x56c82ba0, full_update=0) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/hw/vga.c:1599 #11 0x5585be27 in vga_update_display (opaque=0x56c82ba0) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/hw/vga.c:1861 #12 0x556be4e4 in vmsvga_update_display (opaque=0x56c82ba0) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/hw/vmware_vga.c:954 #13 0x5562435c in vga_hw_update () at console.c:167 #14 0x5573e962 in vnc_refresh (opaque=0x7fffec337010) at ui/vnc.c:2475 #15 0x556f2161 in qemu_run_timers (clock=0x5643a1b0) at qemu-timer.c:420 #16 0x556f23e9 in qemu_run_all_timers () at qemu-timer.c:483 #17 0x556c1e64 in main_loop_wait (nonblocking=0) at main-loop.c:468 #18 0x556b6a76 in main_loop () at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/vl.c:1482 #19 0x556bbc9a in main (argc=43, argv=0x7fffe298, envp=0x7fffe3f8) at /home/justinlw/src/qemu/qemu-kvm-1.0+noroms/vl.c:3523 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/918791 Title: qemu-kvm dies when using vmvga driver and unity in the guest To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/918791/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 918791] Re: qemu-kvm dies when using vmvga driver and unity in the guest
I can reproduce this with upstream qemu - though i must point out that to do so i had to change the definition of VGA_RAM_SIZE in hw/vga_int.h to 16*1024*1024 (as it is in qemu-kvm) in order to be able to use the default high resolution. Command line was: ./x86_64-softmmu/qemu-system-x86_64 -vga vmware -m 1024 -drive file=../../victim.img,if=virtio,cache=none,index=0 -vnc :1 -enable-kvm where victim.img is an ubuntu Precise desktop image running ubuntu-2d. I open a terminal, move it to the launcher bar to make it auto-hide; click 'x' to close the terminal.
