Title:
fanctl does not stop setup on first match
Status in ubuntu-fan package in Ubuntu:
Fix Released
Status in ubuntu-fan source package in Xenial:
Fix Committed
Status in ubuntu-fan source package in Zesty:
Fix Released
Bug description:
SRU Justification (Zesty/Xenial)
Impact: When /etc/network/fan contains two entries for the same
mapping (for example on mapping for the generic network mapping and
one for a specific interface) it will try to set up the same Fan
bridge twice.
Fix: Modify fanctl to only bring up enabled networks in auto mode and
to correctly apply the most specific local configuration.
Testcase: If in an environment that uses one of the 192.168.0.0/16 subnets,
and host has for example a 192.168.1.0/24 address. Then trying to use
fanatic enable-fan -u 192.168.1.x/24 -o 250.0.0.0/8
would show an error now and with the fix applied work ok.
Regression Potential: We tested both cases of using an
underlay/overlay combination which is in the template section and one
that was using a subset for the underlay. The former was working
before the latter not. For that reason we anticipate a low risk of
regression.
