Title:
create_security_group code may get into endless loop
Status in neutron:
Fix Released
Status in neutron kilo series:
Fix Released
Bug description:
That damn piece of code again.
In some cases when network is created for tenant and default security group
is created in the process, there may be concurrent network or sg creation
happening.
That leads to a condition when the code fetches default sg, it's not there,
tries to add it - it's already there, then it tries to fetch it again, but due
to REPEATABLE READ isolation method, the query returns empty result, as in the
first attempt.
As a result, such logic will hang in the loop forever.
Reproducible with rally create_and_delete_ports test.
