I don't see the Test Case from the bug description having been done in
the comment regarding this a verified for Ubuntu 20.04, subsequently I'm
flipping the tags back to verification needed.

2020-08-20 Thread Robie Basak
Hello Dan, or anyone else affected,

Accepted ceph into focal-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/ceph/15.2.3-0ubuntu0.20.04.2 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, what testing has been
performed on the package and change the tag from verification-needed-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. 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 for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

[Bug 1891567] Re: [SRU] ceph_osd crash in _committed_osd_maps when failed to encode first inc map

2020-08-19 Thread Dan Hill
** Description changed:

  [Impact]
  Upstream tracker: issue#46443 [0].
  
  The ceph-osd service can crash when processing osd map updates.
  
  When the osd encounters a CRC error while processing an incremental map
  update, it will request a full map update from its peers. In this code
  path, an uninitialized variable was recently introduced and that will
  get de-referenced causing a crash.
  
  The uninitialized variable was introduced in nautilus 14.2.10, and
  octopus 15.2.1.
  
  [Test Case]
  # Inject osd_inject_bad_map_crc_probability = 1
  sudo ceph daemon osd.{id} config set osd_inject_bad_map_crc_probability 1
  
  # Trigger some osd map updates by restarting a different osd
  sudo systemctl restart osd@{diff-id}
  
  [Regression Potential]
- The code has been updated to leave handle_osd_maps() early if a CRC error is 
encountered, therefore preventing the commit if the failure is encountered 
while processing an incremental map update. This will make the full map update 
take longer but should prevent the crash that resulted in this bug. 
Additionally _committed_osd_maps() is now coded to abort if first <= last, but 
it is assumed that code should never be reached.

[Bug 1891567] Re: [SRU] ceph_osd crash in _committed_osd_maps when failed to encode first inc map

2020-08-19 Thread Robie Basak
A fix for this is in groovy-proposed (since 15.2.3-0ubuntu2 like Corey
said) but not migrated yet, so I'll adjust that task to Fix Committed so
it doesn't look like the SRU is going in ahead of it.
