Description:

Singularity was updated to version 2.6.0, bringing features, bugfixes and
security fixes.

Security issues fixed:

– CVE-2018-12021: Fixed access control on systems supporting overlay file
system (boo#1100333).

Highlights of 2.6.0:

– Allow admin to specify a non-standard location for mksquashfs binary at
build time with ‘–with-mksquashfs’ option #1662
– ‘–nv’ option will use
[nvidia-container-cli](https://github.com/NVIDIA/libnvidia-container) if
installed #1681
– [nvliblist.conf]
(https://github.com/singularityware/singularity/blob/master/etc/nvliblist.c
onf) now has a section for binaries #1681
– ‘–nv’ can be made default with all action commands in singularity.conf
#1681
– ‘–nv’ can be controlled by env vars ‘$SINGULARITY_NV’ and
‘$SINGULARITY_NV_OFF’ #1681
– Restore shim init process for proper signal handling and child reaping
when container is initiated in its own PID namespace #1221
– Add ‘-i’ option to image.create to specify the inode ratio. #1759
– Bind ‘/dev/nvidia*’ into the container when the ‘–nv’ flag is used in
conjuction with the ‘–contain’ flag #1358
– Add ‘–no-home’ option to not mount user $HOME if it is not the $CWD and
‘mount home = yes’ is set. #1761
– Added support for OAUTH2 Docker registries like Azure Container Registry
#1622

Highlights of 2.5.2:

– a new `build` command was added to replace `create` + `bootstrap`
– default image format is squashfs, eliminating the need to specify a size
– a `localimage` can be used as a build base, including ext3, sandbox, and
other squashfs images
– singularity hub can now be used as a base with the uri
– Restore docker-extract aufs whiteout handling that implements correct
extraction of docker container layers.

Bug fixes:

– Fix 404 when using Arch Linux bootstrap #1731
– Fix environment variables clearing while starting instances #1766
– several more bug fixes, see CHANGELOG.md for details
