| * remove instantes of using IntoRawFd in unsafe blocksZach Reizner2020-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The trait IntoRawFd isn't marked unsafe, but its documentation says that an impl must return a uniquely owned RawFd. Some code blocks depended on that behavior to ensure safety with the unsafe File::from_raw_fd, but this leads to a soundness hole where a nominally safe impl of IntoRawFd can lead to unsafety in functions that had been left as safe. This change sidesteps the issue by not using IntoRawFd, and using only safe conversions instead.

| * descriptor_utils: Add write_iter methodChirantan Ekbote2020-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a method to write a series of objects produced by an iterator. Unlike the current `consume` method, this doesn't require the caller to first store the objects in an intermediate collection. Also change `consume` to be implemented using `write_iter`. This is the Writer equivalent of the `iter` and `collect` methods of the Reader struct.

| * Stop tracking sub-mappings in MemoryMappingArenaChirantan Ekbote2020-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel already takes care of tracking all our memory mappings. Doing it again ourselves doesn't provide any benefit and also adds additional restrictions (like not being able to overlap with existing mappings or partially remove mappings). Additionally, the `MemoryMappingArena` will already unmap the entire memory mapped region so there is no need to individually unmap the sub-mappings. The kernel's mmap api doesn't have these restrictions and as far as I can tell there are no safety concerns with allowing this behavior so just stop tracking the sub-mappings. Safe use of MAP_FIXED only requires that the address is part of a previously mmaped region so allow any MemoryMapping to be converted into a MemoryMappedArena.

It still need crosvm vhost-net to trigger irq, which is because the set_vring_call is not directly using the msix irq fd. To optimize this flow to be from vhost-kernel to KVM directly, need: 1. if the msix is enabled and unmasked, use the misx irq fd for the vring_call directly so that all the misx injection can directly to KVM from vhost-kernel. 2. if the msix is disabled or masked, use the indirect vhost_interrupt fd to let the crosvm to control the irq injection.
