Singularity 3.5.3 is a bugfix release with the following changes and fixes:

Changed defaults / behaviours

The following minor behaviour changes have been made in 3.5.3 to allow correct operation on CRAY CLE6, and correct an issue with multi-stage image builds that was blocking use by build systems such as Spack:

  • Container action scripts are no longer bound in from etc/actions.d on the host. They are created dynamically and inserted at container startup.
  • %files from ... will no longer follow symlinks when copying between stages in a multi stage build, as symlinks should be copied so that they resolve identically in later stages. Copying %files from the host will still maintain previous behavior of following links.

Bug Fixes

  • Bind additional CUDA 10.2 libs when using the --nv option without nvidia-container-cli.
  • Fix an NVIDIA persistenced socket bind error with --writable.
  • Add detection of ceph to allow workarounds that avoid issues with sandboxes on ceph filesystems.
  • Ensure setgid is inherited during make install.
  • Ensure the root directory of a build has owner write permissions, regardless of the permissions in the bootstrap source.
  • Fix a regression in %post and %test to honor the -c option.
  • Fix an issue running %post when a container doesn't have /etc/resolv.conf or /etc/hosts files.
  • Fix an issue with UID detection on RHEL6 when running instances.
  • Fix a logic error when a sandbox image is in an overlay incompatible location, and both overlay and underlay are disabled globally.
  • Fix an issue causing user namespace to always be used when allow-setuid=no was configured in a setuid installation.
  • Always allow key IDs and fingerprints to be specified with or without a 0x prefix when using singularity keys
  • Fix an issue preventing joining an instance started with --boot.
  • Provide a useful error message if an invalid library:// path is provided.
  • Bring in multi-part upload client functionality that will address large image upload / proxied upload issues with a future update to Sylabs cloud.

In addition, numerous improvements have been made to the test suites, allowing them to pass cleanly on a range of kernel versions and distributions that are not covered by the open-source CI runs.

Many thanks to those who have contributed code, bug reports, and testing!
