Automatic merge from submit-queue (batch tested with PRs 62657, 63278, 62903, 63375). If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Add more volume types in e2e and fix part of them. **What this PR does / why we need it**: - Add dir-link/dir-bindmounted/dir-link-bindmounted/bockfs volume types for e2e tests. - Fix fsGroup related e2e tests partially. - Return error if we cannot resolve volume path. - Because we should not fallback to volume path, if it's a symbolic link, we may get wrong results. To safely set fsGroup on local volume, we need to implement these two methods correctly for all volume types both on the host and in container: - get volume path kubelet can access - paths on the host and in container are different - get mount references - for directories, we cannot use its mount source (device field) to identify mount references, because directories on same filesystem have same mount source (e.g. tmpfs), we need to check filesystem's major:minor and directory root path on it Here is current status: | | (A) volume-path (host) | (B) volume-path (container) | (C) mount-refs (host) | (D) mount-refs (container) | | --- | --- | --- | --- | --- | | (1) dir | OK | FAIL | FAIL | FAIL | | (2) dir-link | OK | FAIL | FAIL | FAIL | | (3) dir-bindmounted | OK | FAIL | FAIL | FAIL | | (4) dir-link-bindmounted | OK | FAIL | FAIL | FAIL | | (5) tmpfs| OK | FAIL | FAIL | FAIL | | (6) blockfs| OK | FAIL | OK | FAIL | | (7) block| NOTNEEDED | NOTNEEDED | NOTNEEDED | NOTNEEDED | | (8) gce-localssd-scsi-fs| NOTTESTED | NOTTESTED | NOTTESTED | NOTTESTED | - This PR uses `nsenter ... readlink` to resolve path in container as @msau42 @jsafrane [suggested](https://github.com/kubernetes/kubernetes/pull/61489#pullrequestreview-110032850). This fixes B1:B6 and D6, , the rest will be addressed in https://github.com/kubernetes/kubernetes/pull/62102. - C5:D5 marked `FAIL` because `tmpfs` filesystems can share same mount source, we cannot rely on it to check mount references. e2e tests passes due to we use unique mount source string in tests. - A7:D7 marked `NOTNEEDED` because we don't set fsGroup on block devices in local plugin. (TODO: Should we set fsGroup on block device?) - A8:D8 marked `NOTTESTED` because I didn't test it, I leave it to `pull-kubernetes-e2e-gce`. I think it should be same as `blockfs`. **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes # **Special notes for your reviewer**: **Release note**: ```release-note NONE ``` |
