dhcp: Support RedHat dhcp rfc3442 lease format for option 121 (#76)

2019-12-10T00:48:37+00:00

RedHat dhcp client writes out rfc3442 classless-static-routes in a different format[1] than what is found in isc-dhcp clients. This patch adds support for the RedHat format. 1. Background details on the format https://bugzilla.redhat.com/show_bug.cgi?id=516325 https://github.com/vaijab/fedora-dhcp/blob/e83fb19c51765442d77fa60596bfdb2b3b9fbe2e/dhcp-rfc3442-classless-static-routes.patch#L252 https://github.com/heftig/NetworkManager/blob/f56c82d86122fc45304fc829b5f1e4766ed51589/src/dhcp-manager/nm-dhcp-client.c#L978 LP: #1850642

network_state: handle empty v1 config (#45)

2019-12-07T04:11:12+00:00

Sending a valid but empty v1 network config resulted in a stacktrace during execution. Update the network_state parse path to specific check if the 'config' key is None (not present) versus being present but explicitly empty. Also add some network_state unittests. LP: #1852496

get_interfaces: don't exclude bridge and bond members

2019-10-04T15:34:41+00:00

The change that introduced this issue was handling interfaces that are bonded in the kernel, in a way that doesn't present as "a bond" to userspace in the normal way. Both members of this "bond" will share a MAC address, so we filter one of them out to avoid incorrect MAC address collision warnings. Unfortunately, the matching condition was too broad, so that change also affected normal bonds and bridges. This change specifically excludes bonds and bridges from that determination, to address that regression. LP: #1846535

net: add is_master check for filtering device list

2019-09-17T10:11:00+00:00

Some network devices are transformed into a bond via kernel magic and do not have the 'bonding' sysfs attribute, but like a bond they have a duplicate MAC of other bond members. On Azure Advanced Networking SRIOV devices are auto bonded and will have the same MAC as the HyperV nic. We can detect this via the 'master' sysfs attribute in the device sysfs path and this patch adds this to the list of devices we ignore when enumerating device lists. LP: #1844191

net,Oracle: Add support for netfailover detection

2019-09-09T21:13:01+00:00

Add support for detecting netfailover[1] device 3-tuple in networking layer. In the Oracle datasource ensure that if a provided network config, either fallback or provided config includes a netfailover master to remove any MAC address value as this can break under 3-netdev as the other two devices have the same MAC. 1. https://www.kernel.org/doc/html/latest/networking/net_failover.html

azure/net: generate_fallback_nic emits network v2 config instead of v1

2019-08-13T20:13:05+00:00

The function generate_fallback_config is used by Azure by default when not consuming IMDS configuration data. This function is also used by any datasource which does not implement it's own network config. This simple fallback configuration sets up dhcp on the most likely NIC. It will now emit network v2 instead of network v1. This is a step toward moving all components talking in v2 and allows us to avoid costly conversions between v1 and v2 for newer distributions which rely on netplan.

net: update net sequence, include wait on netdevs, opensuse netrules path

2019-07-17T20:23:42+00:00

On systems with many interfaces, processing udev events may take a while. Cloud-init expects devices included in a provided network-configuration to be present when attempting to configure them. This patch adds a step in net configuration where it will check for devices provided in the configuration and if not found, issue udevadm settle commands to wait for them to appear. Additionally, the default path for udev persistent network rules 70-persistent-net.rules may also be written to systems which include the 75-net-generator.rules. During boot, cloud-init and the generator may race and interleave values causing issues. OpenSUSE will now use a newer file, 85-persistent-net-cloud-init.rules which will take precedence over values created by 75-net-generator and avoid collisions on the same file. LP: #1817368

net: add rfc3442 (classless static routes) to EphemeralDHCP

2019-07-16T22:40:15+00:00

The EphemeralDHCP context manager did not parse or handle rfc3442 classless static routes which prevented reading datasource metadata in some clouds. This branch adds support for extracting the field from the leases output, parsing the format and then adding the required iproute2 ip commands to apply (and teardown) the static routes. LP: #1821102

git tests: no longer show warning about safe yaml.

2019-04-27T02:40:47+00:00

Currently on 18.04, running tox -e py27 will spew errors like: .tests/unittests/test_net.py:2649: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details. The change here just uses cloud-init's yaml, which does safeloading by default.
