[ANNOUNCE] unionmount-testsuite: master branch updated to 509b1e7

[Amir Goldstein]

Hi All,

The master branch on the unionmount-testsuite tree [1] has been updated.

Changes in this update:
- Support for testing a FUSE implementation of overlayfs

Tested with fuse-overlayfs [2], which does not support redirect_dir=on:
  ./run --ov --fuse=fuse-overlayfs --xdev

Thanks,
Amir.

509b1e7 Ignore overlay kernel module params when testing FUSE

New commits:

Amir Goldstein (3):
      Fix layer check for FUSE overlayfs
      Expect EXDEV on ovelray dir rename with old kernels
      Ignore overlay kernel module params when testing FUSE implementation

Giuseppe Scrivano (1):
      Support testing a FUSE implementation of overlayfs

Hi All,

The master branch on the unionmount-testsuite tree [1] has been updated.

Changes in this update:
- Enhance --verify with copy up state checks
- Verify metadata only copy up with --verify --meta
- Verify unified ino domain with xino requires --verify --xino

Note that this release changes xino from a test configuration that is
implied from --verify to requiring an explicit opt-in with --xino option.

This change allows more strict checking of the xino=off configuration
and exposes a kernel v4.17 regression:

 ./run --ov=1 --verify hard-link
 ...
 /mnt/a/no_foo110: File unexpectedly on upper layer

Thanks,
Amir.

1724ef2 Decouple xino configuration from --verify

New commits:

Amir Goldstein (8):
  Fix ./run --ov --verify --recycle
  Simplify initialization of __upper
  Fix instantiation of hardlinked dentry
  Record meta copy_up vs. data copy_up
  Check that files were copied up as expected
  Reset dentry copy_up state on upper layer rotate
  Check that data was not copied up with metacopy=on
  Decouple xino configuration from --verify

[ANNOUNCE] unionmount-testsuite: master branch updated to dc24a45

Hi All,

The master branch on the unionmount-testsuite tree [1] has been updated.

Changes in this update:
- Align with v5.6-rc1 overlayfs code

The previous release of unionmount-testsuite (1724ef2) exposed a kernel
v4.17 regression:

 ./run --ov=1 --verify hard-link
 ...
 /mnt/a/no_foo110: File unexpectedly on upper layer

This kernel regression was fixed in v5.6-rc1 by commit  b7bf9908e17c
("ovl: fix corner case of non-constant st_dev;st_ino").
This release of unionmount-testsuite adapts the layer checks to the fixed
logic of v5.6-rc1.

The regression test above still fails on kernel v5.5, but with a
different error:
 ./run --ov=1 --verify hard-link
 ...
 /mnt/a/no_foo110: inode number/layer changed on copy up (got
34:434190, was 34:430077)


Thanks,
Amir.

[ANNOUNCE] unionmount-testsuite: master branch updated to a9a4f4f

[Amir Goldstein]

Hi All,

The master branch on the unionmount-testsuite tree [1] has been updated.

Changes in this update:
- Support testing nested overlayfs configurations

The following test arguments:

    ./run --ovov --xino --verify

setup a non-samefs nested overlay with --xino and demonstrate the
best effort nature of xino - upper inode numbers are in the xino domain
and lower inode numbers overflow xino bits and fallback to lower layer
pseudo st_dev and the lower overlay st_ino.

This was used to develop the recently merged ovl-ino changes.

Thanks,
Amir.
