This is the first bugfix release for Singularity 3.5

New features / functionalities

A single feature has been added in the bugfix release, with specific
functionality:

  • A new option allow container encrypted can be set to no in
    singularity.conf to prevent execution of encrypted containers.

Bug Fixes

This bugfix release addresses the following issues:

  • Fixes a disk space leak when building from docker-archive.
  • Makes container process SIGABRT return the expected code.
  • Fixes the inspect command in unprivileged workflows.
  • Sets an appropriate default umask during build stages, to avoid issues with
    very restrictive user umasks.
  • Fixes an issue with build script content being consumed from STDIN.
  • Corrects the behavior of underlay with non-empty / symlinked CWD and absolute
    symlink binds targets.
  • Fixes execution of containers when binding BTRFS filesystems.
  • Fixes build / check failures for MIPS & PPC64.
  • Ensures file ownership maintained when building image from sandbox.
  • Fixes a squashfs mount error on kernel 5.4.0 and above.
  • Fixes an underlay fallback problem, which prevented use of sandboxes on
    lustre filesystems.

Known Issues

The following are known issues in this release, and will be addressed in an upcoming version of Singularity:

  • Using --fakeroot to build sandboxes to GPFS, and most sandboxes to Lustre filesystems, is known not to work. As a workaround you may built to a local filesystem, e.g./tmp/mysandbox and copy to GPFS/Lustre.
  • Caching of http(s):// image sources is incorrect. Images with the same final part in the URL will be considered the same image. Use --disable-cache or singularity cache clean between runs, or use singularity pull to explicitly fetch the image to a local SIF file.

Thanks to our contributors for code, feedback, and testing efforts!
