![]() Currently libvmmapi provides a way to get a list of the allowed ioctls on the vmm device file, so that bhyve can limit rights on the device file fd. The interface is rather strange: it allocates a copy of the list but returns a const pointer, so the caller has to cast away the const in order to free it without aggravating the compiler. As far as I can see, there's no reason to make a copy of the array, but changing vm_get_ioctls() to not do that would break compatibility. So this change just introduces a better interface: move all rights-limiting logic into libvmmapi. Any new operations on the fd should be wrapped by libvmmapi, so also discourage use of vm_get_device_fd(). Currently bhyve uses it only when limiting rights on the device fd. No functional change intended. Reviewed by: jhb MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D37098 |

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
