vm-memory-v0.12.0

Changelog

[v0.12.0]

Added

• [#241] Add Xen memory
  mapping support: Foreign and Grant. Add new API for accessing pointers to
  volatile slices, as as_ptr() can't be used with Xen's Grant mapping.
• [#237] Implement ByteValued for i/u128.

vm-memory-v0.11.0

Changelog

Added

• [#216] Add GuestRegionMmap::from_region.

Fixed

• [#217] Fix vm-memory internally taking rust-style slices to guest memory in ways that could potentially cause undefined behavior. Removes/deprecates various as_slice/as_slice_mut methods whose usage violated rust's aliasing rules, as well as an unsound impl<'a> VolatileMemory for &'a mut [u8].

vm-memory-v0.10.0

Changed

• [#208] Updated vmm-sys-util dependency to v0.11.0
• [#203] Switched to Rust edition 2021.

vm-memory-v0.9.0

v0.9.0

Fixed

• [#195]:
  mmap::check_file_offset is doing the correct size validation for block and
  char devices as well.

Changed

• [#198]: atomic: enable 64
  bit atomics on ppc64le and s390x.
• [#200]: docs: enable all
  features in docs.rs.
• [#199]: Update the way
  the dependencies are pulled such that we don't end up with incompatible
  versions.

vm-memory-v0.8.0

[v0.8.0]

Fixed

• [#190]:
  VolatileSlice::read/write when input slice is empty.

vm-memory-v0.7.0

[v0.7.0]

Changed

• [#176]: Relax the trait bounds of Bytes auto impl for T: GuestMemory
• [#178]: MmapRegion::build_raw no longer requires that the length of the region is a multiple of the page size.

vm-memory-v0.6.0

[v0.6.0]

Added

• [#160]: Add ArcRef and AtomicBitmapArc bitmap backend implementations.
• [#149]: Implement builder for MmapRegion.
• [#140]: Add dirty bitmap tracking abstractions.

vm-memory-v0.5.0

[v0.5.0]

Added

• [#8]: Add GuestMemory method to return an Iterator
• [#120]: Add is_hugetlbfs() to GuestMemoryRegion
• [#126]: Add VolatileSlice::split_at()
• [#128]: Add VolatileSlice::subslice()

vm-memory-v0.4.0

Fixed

• [#100]: Performance degradation after fixing #95.
• [#122]: atomic, Cargo.toml: Update for arc-swap 1.0.0.

vm-memory-v0.3.0

Added

• [#109]: Added build_raw to MmapRegion which can be used to operate on externally created mappings.
• [#101]: Added check_range for GuestMemory which could be used to validate a range of guest memory.
• [#115]: Add methods for atomic access to Bytes.

Fixed

• [#93]: DoS issue when using virtio with rust-vmm/vm-memory.
• [#106]: Asserts trigger on zero-length access.

Removed

• integer-atomics is no longer a distinct feature of the crate.
