Upcoming Release

[v0.13.0]

Added

  • [#190] Introduce RISC-V64 architecture support.

Changed

  • [#194] Updated vm-memory to 0.16.0.
  • [#197] Re-organize loader, configurator and benches module layout, leaving original interface intact.

[v0.12.0]

Changed

  • [#187] Updated vm-memory to 0.15.0.
  • [#179] Load hvm_modlist_entry into guest memory when requested.
  • [#177] Added loading of PVH module blobs into guest memory. This enables booting with initrd via PVH boot.

[v0.11.0]

Changed

  • [#173] Updated vm-memory to 0.14.0.
  • [#170] Added all features to the generated docs.rs documentation.

[v0.10.0]

Changed

  • [#162] Updated vm-memory to 0.13.0. This introduces a ReadVolatile bound on KernelLoader::load.

[v0.9.1]

Fixed

  • [#130] Generate bindings to fix unaligned references in unit tests.
  • [#160] Update vm-memory to 0.12.2

[v0.9.0]

Fixed

  • [#71] Fix incorrect alignment for ELF notes, starting address of name field and descriptor field have a 4-byte alignment.

[v0.8.1]

Fixed

  • [#125] The ELF header contains offsets that the loader uses to find other structures. If those offsets are beyond the end of the file (or would go past the end of the file) it is essential to error out when attempting to read those.

Added

  • Add a new criterion advisory to ignore list 2580d4

[v0.8.0]

Changed

  • Updated vm-memory from 0.9.0 to 0.10.0

[v0.7.0]

Added

  • Added insert_init_args method allowing insertion of init arguments into Cmdline.

Changed

  • Removed InvalidDevice error type (it wasn't used anywhere).
  • Replaced From with TryFrom<Cmdline> for Vec<u8> to be able to propagate errors returned by as_cstring when converting a Cmdline to Vec<u8>.
  • Support added for both boot and init arguments in try_from.
  • Changed new to return Result for invalid command line capacity handling.

[v0.6.0]

Changed

  • Crate is now using edition 2021.

Added

  • Derived Eq for Error types and the PvhBootCapability enum.

Fixed

  • Fixed a bug in load_cmdline due to which the command line was not null terminated. This resulted in a change in the Cmdline API where instead of returning the cmdline as a String, we're now returning it as a CString as the latter has support for converting it to a null terminated bytes array.
  • Fixed an off-by-one error in load_cmdline, where we were doing validations on the first address after the command line memory region, instead of the last inclusive one of it.

[v0.5.0]

Fixed

  • [#104] Fixed the --no-default-features not working.

Changed

  • [#111] Use caret requirements for dependencies.

Added

  • [#99] Implement Debug and PartialEq for CmdLine.
  • [#100] Added Clone derive for CmdLine.

[v0.4.0]

Fixed

  • [#66] Fixed potential overflow in calls to align_up.

Changed

  • [#62] The load_cmdline function now takes as a parameter the crate defined Cmdline object instead of Cstr. This means that customers don't need to convert the object before calling into load_cmdline.
  • [#83] Updated the vm-memory dependency requirement to the latest version (0.6.0).

Added

  • [#79] Implemented From<Cmdline> for Vec<u8>. This replaces the obsolete Into implementation.

[v0.3.0]

Fixed

  • Replaced panic condition in align_up with returning an Error.
  • Fixed potential hang condition in Elf::load caused by arithmetic overflow.
  • Disallow overflow when computing the kernel load address when loading ELF.
  • Fix unchecked arithmetic in BzImage::load that could lead to undefined behavior.

Added

  • Added functions for specifying virtio MMIO devices when building the kernel command line.
  • Added a function to specify multiple values in key=values pairs when building the kernel command line.

[v0.2.0]

Added

  • Added traits and structs for loading ELF (vmlinux), big zImage (bzImage) and PE (Image) kernels into guest memory.
  • Added traits and structs for writing boot parameters to guest memory.
