Description Juan Hernández 2017-09-28 11:45:06 EDT

Description of problem:

When use of the oVirt SDK is enabled the events worker may sporadically crash the worker due to a segmentation violation.

Version-Release number of selected component (if applicable):

CFME 5.9.0 (latest master branch)
SDK 4.1.8 (latest stable release)

How reproducible:

In order to reproduce this the use of the SDK has to be enabled, and the events worker has to send simultaneously two requests to the server. This isn't easy to reproduce, as it depends on timing. But it is easy to reproduce in the SDK itself, see bug 1496846.

Steps to Reproduce:

None.

Actual results:

The events worker crashes due to a segmentation fault.

Expected results:

The events worker shouldn't crash.

Additional info:

This issue should only affect newer versions of CFME, were the SDK is enabled by default and the connections are optimised to use one per worker. But I think that we should update older versions of CFME (5.8 and 5.7) to use the fixed version of the SDK once it is available, just in case.

Comment 2 Juan Hernández 2017-10-16 06:52:43 EDT

The potential crash has been resolved in version 4.1.9 of the SDK. The provider needs now to be updated to use this version of the SDK:

  Require oVirt Ruby SDK 4.1.9 or newer
  https://github.com/ManageIQ/manageiq-providers-ovirt/pull/107

Upstream this will happen automatically, but downstream the RPM for the SDK needs to be updated explicitly. Satoe, can you help us with that?

Comment 3 Satoe Imaishi 2017-10-16 09:02:04 EDT

No problem. Will update the downstream rpm after the PR is merged.

Comment 4 Ilanit Stein 2017-12-13 06:17:47 EST

Moving to Verified based on bug 1496846 verification.
On CFME latest (5.9.0.12), the oVirt Ruby SDK version is:
rh-ruby23-rubygem-ovirt-engine-sdk4-4.1.13-1.el7cf.x86_64,
and fix was included in SDK 4.1.9.
