[Kernel-packages] [Bug 1754584] Re: zfs system process hung on container stop/delete

[Brad Figg]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
  == SRU Request [Xenial][Artful] ==

  == Justification ==

  It is possible to hang zfs asynchronous reads if a read to a page that
  is mmap'd onto the the file being read is the same offset in the
  mapping as in the file. This is caused by two lock operations on the
  page.

  == Fix ==

  Upstream ZFS fix to ensure the page is not double-locked during async
  I/O of one or more pages.

  == Testing ==

  Create a zfs pool + zfs file system, run the reproducer program in
  comment #28 on the zfs filesystem.  Without the fix this can lock up,
  with the fix this runs to completion.

  == Regression Potential ==

  Minimal, the locking fix addresses a fundamental bug in the locking

[Kernel-packages] [Bug 1754584] Re: zfs system process hung on container stop/delete

[Joshua Powers]

Using two NUCs, one with Xenial and one with Artful I was able to verify
both the kernel and zfs fixes. Marking verification-done-artful and
erification-done-xenial

Artful log: https://paste.ubuntu.com/p/jjZWTNqPjS/

Artful versions:
zfsutils-linux: 0.6.5.6-0ubuntu20
linux-signed-generic: 4.4.0.121.127


Xenial log: https://paste.ubuntu.com/p/b6gvKbpgWC/

Xenial versions:
zfsutils-linux: 0.6.5.11-1ubuntu3.3
linux-signed-generic: 4.13.0.39.42

  == SRU Request [Xenial][Artful] ==

  == Justification ==

  It is possible to hang zfs asynchronous reads if a read to a page that
  is mmap'd onto the the file being read is the same offset in the
  mapping as in the file. This is caused by two lock operations on the
  page.

  == Fix ==

  Upstream ZFS fix to ensure the page is not double-locked during async
  I/O of one or more pages.

  == Testing ==

  Create a zfs pool + zfs file system, run the reproducer program in
  comment #28 on the zfs filesystem.  Without the fix this can lock up,
  with the fix this runs to completion.

  == Regression Potential ==

  Minimal, the locking fix addresses a fundamental bug in the locking
  and this should not affect ZFS read/write I/O with this fix.

[Kernel-packages] [Bug 1754584] Re: zfs system process hung on container stop/delete

[Joshua Powers]

I am marking this verification-failed as my steps to reproduce this and
the ones in step #24 still fail in Bionic, Artful, and Xenial.

Bionic: 0.7.5-1ubuntu12
https://paste.ubuntu.com/p/mWVnhdFpRp/

Artful: 0.6.5.11-1ubuntu3.3
https://paste.ubuntu.com/p/RQmxNS7Vxn/

Xenial: 0.6.5.6-0ubuntu20

Bug description:
  == SRU Request [Xenial][Artful] ==

  == Justification ==

  It is possible to hang zfs asynchronous reads if a read to a page that
  is mmap'd onto the the file being read is the same offset in the
  mapping as in the file. This is caused by two lock operations on the
  page.

  == Fix ==

  Upstream ZFS fix to ensure the page is not double-locked during async
  I/O of one or more pages.

  == Testing ==

  Create a zfs pool + zfs file system, run the reproducer program in
  comment #28 on the zfs filesystem.  Without the fix this can lock up,
  with the fix this runs to completion.

  == Regression Potential ==

  Minimal, the locking fix addresses a fundamental bug in the locking
  and this should not affect ZFS read/write I/O with this fix.

@colin - is there a requirement to have a newer kernel and not just a
newer zfs-linux for this to be fixed?

[Kernel-packages] [Bug 1754584] Re: zfs system process hung on container stop/delete

[Brian Murray]

Hello Joshua, or anyone else affected,

Accepted zfs-linux into artful-proposed. The package will build now and
be available at https://launchpad.net/ubuntu/+source/zfs-
linux/0.6.5.11-1ubuntu3.3 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-artful to verification-done-artful. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-artful. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!
