** Description changed: - Some docker users are getting a "permission denied" error with overlayfs - in some situations. 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. + 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. + + 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. + + --- + + 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.
