When labels with more than 15 characters are used for addresses, the
ifup/ifdown commands fail due to the hard limit on label length imposed
by the linux kernel. The label for addresses in starlingx is composed by
the interface name followed by a colon and a string in the format
<network_id>-<address_id>, which can surpass the 15 character limit if
the interface name is sufficiently long.
For example: enp0s10vlan100:0-35
This commit patches the ifupdown package to add a conditional to the
source code where the 'ip' command is formatted. The conditional
replaces the label name by the interface name itself, if the former is
more than 15 characters long.
Test plan
Setup:
- System: AIO-SX
- Interfaces:
> enp0s8: ethernet, assigned to mgmt and cluster-host networks
> enp0s9: bond slave
> enp0s10: bond slave
> bond0longname: bond on top of enp0s9 and enp0s10, data
> vlanshort: vlan id 300 on top of bond0longname, data
> vlan400longname: vlan id 400 on top of bond0longname, data
- Both mgmt and cluster-host networks are dual stack
- All data interfaces have both IPv4 and IPv6 static addresses
[PASS] Run ifup command individually for all labels, check that
addresses are correctly assigned
[PASS] Run ifdown command individually for all labels, check that
addresses are correctly removed
[PASS] Manually change MTU value in /etc/network/interfaces.d/ifcfg-*
files for enp0s8 and enp0s9, call /usr/local/bin/
apply_network_config.sh script, check that all interfaces were
correctly configured (changing MTU causes the affected interfaces
and all the dependent ones and corresponding labels to be put
down and up again, logs are in /var/log/user.log)
