vm-memory-v0.17.0

Changelog

[v0.17.0]

Added

• [#311] Allow compiling without the ReadVolatile and WriteVolatile implementations
• [#312] GuestRegionContainer, a generic container of GuestMemoryRegions, generalizing GuestMemoryMmap (which
  is now a type alias for GuestRegionContainer<GuestRegionMmap>).
• [#338] Make GuestMemoryAtomic always implement Clone.
• [#338] Make GuestAddressSpace a subtrait of Clone.
• [#339] Add GuestMemory::get_slices()

Changed

• [#307] Move read_volatile_from, read_exact_volatile_from,
  write_volatile_to and write_all_volatile_to functions from the GuestMemory trait to the Bytes trait.
• [#312]: Give GuestMemory::find_region and GuestMemory::num_regions
  a default implementation, based on linear search.
• [#312]: Provide a marker trait, GuestMemoryRegionBytes, which enables a default implementation of Bytes<MemoryRegionAddress>
  for a GuestMemoryRegion if implemented.
• [#312]: Adjust error types returned from GuestMemoryMmap::from_ranges[_with_files]
  and GuestRegionMmap::from_range to be separate from the error type returned by GuestRegionCollection functions.
  Change return type of GuestRegionMmap::new from Result to Option.
• [#324] GuestMemoryRegion::bitmap() now returns a BitmapSlice. Accessing the full bitmap is now possible only if the type of the memory region is know, for example with MmapRegion::bitmap().
• [#339] Implement Bytes::load() and Bytes::store() with get_slices() instead of to_region_addr()

Removed

• [#307] Remove deprecated functions Bytes::read_from, Bytes::read_exact_from,
  Bytes::write_to, Bytes::write_all_to, GuestMemory::as_slice, GuestMemory::as_slice_mut, GuestMemory::with_regions,
  GuestMemory::with_regions_mut, GuestMemory::map_and_fold, VolatileSlice::as_ptr, VolatileRef::as_ptr, and
  VolatileArrayRef::as_ptr.
• [#320] Drop check_file_offset check when using MmapRegionBuilder.
  The mmap(2) syscall itself already validates that offset and length are valid, and trying to replicate this check
  in userspace ended up being imperfect.

Fixed

• [#339] Fix Bytes::read() and Bytes::write() not to ignore try_access()'s count parameter

Deprecated

• [#349] Deprecate GuestMemory::try_access(). Use GuestMemory::get_slices() instead.

• [#270] atomic_bitmap: add capability to reset bits range
• [#285] Annotated modules in lib.rs to indicate their feature
  dependencies such that it is reflected in the docs, enhancing documentation clarity for users.

Changed

• [#275] Fail builds on non 64-bit platforms.

Fixed

  that made it copy data it chunks of 4096.

vm-memory-v0.14.1

Changelog

[v0.14.1]

Fixed

• [#279] Remove restriction from read_volatile_from and write_volatile_into that made it copy data it chunks of 4096.

Changelog

[v0.14.0]

Added

• [#266] Derive Debug for several types that were missing it.

Changed

• [#274] Drop Default as requirement for ByteValued.

vm-memory-v0.13.1

Changelog

[v0.13.1]

Added

• [#256] Implement WriteVolatile for std::io::Stdout.
• [#256] Implement WriteVolatile for std::vec::Vec.
• [#256] Implement WriteVolatile for Cursor<&mut [u8]>.
• [#256] Implement ReadVolatile for Cursor<T: AsRef[u8]>.

vm-memory-v0.13.0

Changelog

[v0.13.0]

Added

• [#247] Add ReadVolatile and
  WriteVolatile traits which are equivalents of Read/Write with volatile
  access semantics.

Changed

• [#247] Deprecate
  Bytes::{read_from, read_exact_from, write_to, write_all_to}. Instead use
  ReadVolatile/WriteVolatile, which do not incur the performance penalty
  of copying to hypervisor memory due to Read/Write being incompatible
  with volatile semantics (see also #217).

vm-memory-v0.12.2

Changelog

[v0.12.2]

Fixed

• [#251]: Inserted checks that verify that the value returned by VolatileMemory::get_slice is of
  the correct length.

Deprecated

• [#244] Deprecate volatile memory's as_ptr() interfaces. The new interfaces to be used instead are:
  ptr_guard() and ptr_guard_mut().
