* kern: allow kern_shm_open2 of an anonymous preconstructed shmfdKyle Evans7 days1-1/+1
| | | | | | | | | | | The motivation here is for future changes to the coredump code to be able to build up a coredump into a shmfd instead of a vnode, which then gets tapped out to userland via a character device. This also opens up the possibility that it's useful for the kernel to be able to construct a shmfd and pass it out to a process that shouldn't need to write to it.

* Abstract UIO allocation and deallocation.Alfredo Mazzinghi2024-02-101-3/+3
| | | | | | | | | | | | | Introduce the allocuio() and freeuio() functions to allocate and deallocate struct uio. This hides the actual allocator interface, so it is easier to modify the sub-allocation layout of struct uio and the corresponding iovec array.
