Title:
bulk create gre/vxlan network failed
Status in OpenStack Neutron (virtual network service):
Invalid
Bug description:
I bulk create 1000 vxlan networks, it always failed, I analyze the reason is
bellow:
it does not lock when it allocate segment id
def allocate_fully_specified_segment(self, session, **raw_segment):
network_type = self.get_type()
try:
with session.begin(subtransactions=True):
alloc = (session.query(self.model).filter_by(**raw_segment).
first())
def allocate_partially_specified_segment(self, session,
**filters):
network_type = self.get_type()
with session.begin(subtransactions=True):
select = (session.query(self.model).
filter_by(allocated=False, **filters))
I think it should add a lock when it allocate segment id
