  • Utils must support higher level API to create Tar with chrooted into directory
  • Volume export: use TarwithChroot instead of Tar so we can make sure no symlink can be exported by tar if it exists outside of the source directory.
  • container export: use chroot and Tar instead of Tar so we can make sure no symlink can be exported by tar if it exists outside of the mointPoint.

Race needs combination of external/in-container mechanism which is hard to repro in CI.

@ashley-cui We're going to need a new upstream release off v4.4 today or tomorrow to get this landed.

mheon commented Feb 16, 2023

Actually, scratch v3.0.1-rhel - the feature hadn't landed by then.

@TomSweeneyRedHat

And FWIW @ashley-cui best case scenario is to get the next spin of v4.4 completed by COB today, so we can have Jindrich build a test module overnight and get it into QE's hands early Friday afternoon their time. But, don't kill yourself for that, tomorrow would be OK if push came to shove.

@flouthoc can you spin up a PR in the 4.4.1-rhel branch please?

@ashley-cui

@TomSweeneyRedHat I'll spin it up as soon as this PR merges and is cherry-picked into the v4.4 branch :)

@TomSweeneyRedHat @ashley-cui We don't do releases for RHEL. v4.4 is upstream - we're doing a v4.4.2 to get a release out to Fedora & Co. as soon as possible. Having the commit in v4.4.1 is sufficient.

Looks like this needs to be manually cherry-picked as it doesn't apply cleanly :(
