Hi, The HP ZBook 15 G3 laptop builtin display (eDP-1) does not work correctly with v4.11-11413-g2868b25. When booting the laptop, the resolution seems to be limited to 1024x768, and gnome-session segfaults. Up to 4.11 the display works just fine in 1920x1080 mode. I'm seeing this in the kernel logs: nouveau 0000:01:00.0: eDP-1: EDID is invalid: [00] BAD 00 ff ff ff ff ff ff 00 ff

vhost_net_clear_ubuf_info didn't clear ubuf_info after kfree, this could trigger double free. Fix this and simplify this code to make it more robust: make sure ubuf info is always freed through vhost_net_clear_ubuf_info.

...Not sure if they affect this particular issue, but thought I'd point it out. Are you fuzzing with multiple threads, or just one at a time? Do you have a branch somewhere public with the changes to add nouveau ioctl support to trinity?
