** Description changed: SRU Justification Impact: Under some conditions docker users using the overlay2 storage driver with xenial kernels will get "permission denied" errors when they should not. This is due to a bug in overlayfs. - Fix: Backport upstream commits from 4.6. + Fix: Backport upstream fix, plus some cleanup to make the backup + cleaner. - Regression Potential: Upstream the patches have been present since 4.6 - so they should be well tested at this point. The backports don't exactly - match the upstream patches so there's some potential for error there, - however no problems were seen in brief testng with docker. + Regression Potential: All changes are straightforward and have low risk + of introducing regressions. --- Due to an issue in overlayfs, in some scenrios docker users can get erroneous "permission denied" errors when using the overlay2 storage driver. When a user has search permissions on the upper dir but not the lower dir they may get this error, where having search permissions for the upper dir should be sufficient. This is fixed by upstream commit 38b78a5f18584db6fa7441e0f4531b283b0e6725. Originally reported at https://github.com/docker/docker/issues/28391.
