When any port in the OVS agent is using a security groups (SG) and
this SG is removed, is marked to be deleted. This deletion process
is done in [1].
The SG deletion process consists on removing any reference of this SG
from the firewall and the SG port map. The firewall removes this SG in
[2].
The information of a SG is stored in:
* ConjIPFlowManager.conj_id_map = ConjIdMap(). This class stores the
conjunction IDS (conj_ids) in a dictionary using the following keys:
ConjIdMap.id_map[(sg_id, remote_sg_id, direction, ethertype,
conj_ids)] = conj_id_XXX
* ConjIPFlowManager.conj_ids is a nested dictionary, built in the
following way:
self.conj_ids[vlan_tag][(direction, ethertype)][remote_sg_id] = \
set([conj_id_1, conj_id_2, ...])
This patch stores all conjuntion IDs generated and assigned to the
tuple (sg_id, remote_sg_id, direction, ethertype). When a SG is
removed, the deletion method will look for this SG in the new storage
variable created, ConjIdMap.id_map_group, and will mark all the
conjuntion IDs related to be removed. That will cleanup those rules
left in the OVS matching:
action=conjunction(conj_id, 1/2)
