Title:
snat_idx and FIP Rules may overlap
Status in neutron:
Expired
Bug description:
FIP rules in agent/l3/dvr_fip_ns.py are given the range:
FIP_PR_START = 32768
FIP_PR_END = FIP_PR_START + 40000
And snat_idx in agent/l3/dvr_router.py used for ip rules as well is computed
using:
if snat_idx < 32768:
snat_idx = snat_idx + MASK_30
So that the FIP rule range could overlap the snat_idx range in rare
cases.
The obvious solution is "if snat_idx <32768+40001"(I think) but
there's probably a better solution than hard coding 40000
