[Bug 1531363] Re: internal server error returned when set gateway of router with an octal ip address
Moved this to neutron since the validation code for ip addresses is done on the back-end. This also looks like a non-issue. Found this in the validation code:
neutron/api/v2/attributes.py:_validate_ip_address
# A leading '0' in IPv4 address may be interpreted as an octal number,
# e.g. 011 octal is 9 decimal. Since there is no standard saying
# whether IP address with leading '0's should be interpreted as octal
# or decimal, hence we reject leading '0's to avoid ambiguity.
Seems pretty clear that the error was thrown deliberately to "avoid ambiguity"
** Project changed: python-neutronclient => neutron

2)internal server error returned when set gateway of router
with an octal ip address:
root@45-59:/opt/stack/devstack# neutron router-gateway-set --fixed-ip subnet_id=
015bc64c-ab58-41a1-a296-b58198cffacc,ip_address=172.168.0.011 router100 ext-net
Request Failed: internal server error while processing your request. >>>>ISSUE
root@45-59:/opt/stack/devstack#
Note: the ip address 172.168.0.011 may be interpreted as octal address since
there is a leading "0" in the address
3) if there is no leading "0" in the address, it's ok:
root@45-59:/opt/stack/devstack#
root@45-59:/opt/stack/devstack# neutron router-gateway-set --fixed-ip
subnet_id=015bc64c-ab58-41a1-a296-b58198cffacc,ip_address=172.168.0.11 router100 ext-net
Set gateway for router router100
root@45-59:/opt/stack/devstack# neutron router-show router100
