2017-07-22sysconfig: support subnet type of 'manual'.Scott Moser
The subnet type 'manual' was used as a way to declare a device and set an MTU for it but not assign network addresses. This updates the manual example config to handle that case and provides expected rendered output for sysconfig, eni, and netplan.
2017-07-21Drop rand_str() usage in DNS redirection detectionBob Aman
Making lots of random invalid DNS queries interferes with the ability of security teams to identify malicious or anomalous behavior from DNS logs. The same goal should be achievable with a consistent query for a name that is disallowed. LP: #1088611
2017-07-20sysconfig: use MACADDR on bonds/bridges to configure mac_addressRyan Harper
Previously, sysconfig rendered HWADDR for all interface types, but that value is only used to identify physical devices. Instead use MACADDR to configure the MAC on virtual devices, like bonds and bridges. - Sort bond slave list to ensure consistent ordering in sysconfig rendered files. - Add unittests for sysconfig rendering of bonds/bridges with mac_address LP: #1701417
2017-07-20net: eni route rendering missed ipv6 default route configRyan Harper
In some network configurations a network value of '::' and a netmask value of '::' were used to indicate a default IPV6 gateway. Commit d00da2d5 removed ipv6 'netmask' attributes and calculate a prefix length value instead. The eni route rendering failed to update the check to use prefix value of 0 to indicate the presence of an IPV6 default route. A broken ipv6 default route rendered like: post-up route add -net :: netmask :: gw 2001:4800:78ff:1b::1 || true And with this patch, it now renders like: post-up route add -A inet6 default gw 2001:4800:78ff:1b::1 || true LP: #1701097
2017-07-20sysconfig: enable mtu set per subnet, including ipv6 mtuRyan Harper
Render MTU values if present in subnet and route configurations for v4 and v6. LP: #1702513
2017-07-20sysconfig: handle manual type subnetsRyan Harper
Implement manual control for sysconfig by using ONBOOT=N. This allows an interface to be configured but not brought up. Note that ONBOOT is per-interface not per address. LP: #1687725
2017-07-20sysconfig: fix ipv6 gateway routesRyan Harper
Currently only the subnet is checked for 'ipv6' setting, however, the routes array may include a mix of v4 or v6 configurations, in particular, the gateway in a route may be ipv6, and if so, should export the value via IPV6_DEFAULTGW in the ifcfg-XXXX file. Additionally, if the route is v6, it should rendering a routes6-XXXX file; this is present but missing the 'dev <interface>' scoping. LP: #1694801
2017-07-20sysconfig: fix rendering of bond, bridge and vlan types.Ryan Harper
Previously, virtual types (bond, bridge, vlan) were almost completely broken. They would not get any network configuration (ip addresses or dhcp config) and or routes rendered. This fixes those issues. For bonds we now correctly render BONDING_SLAVE entries. Also add tests for simple bond, bridge and vlan. LP: #1695092
2017-07-19sysconfig: ipv6 and default gateway fixes.Ryan Harper
With this change, entries in IPV6ADDR and IPV6ADDR_SECONDARIES will now always be in format addr/prefix. When a subnet has a gateway will be written. If the gateway is ipv6, use the key IPV6_DEFAULTGW rather than GATEWAY. LP: #1704872
2017-07-19net: fix renaming of nics to support mac addresses written in upper case.Scott Moser
The network device renaming code previously required the case of the mac address input to match that of the data read from the system. For example, if user provided network config with mac address in upper case, then cloud-init would not rename the device correctly as /sys/class/net/address stores lower case values. The fix here is to always compare lower case mac addresses. LP: #1705147
2017-07-19tests: fixes for issues uncovered when moving to python 3.6.Scott Moser
This includes a few fixes found when testing with python 3.6. - fix eni renderer when target is None This just uses the util.target_path() in the event that target is None. - change test cases to not rely on the cached result of util.get_cmdline() and other cached globals. Update the base TestCase to unset that cache. - mock calls to system_is_snappy from the create_users test cases. - drop unused _pp_root in test_simple_run.py LP: #1703697
2017-07-18sysconfig: include GATEWAY value if set in subnetRyan Harper
Render the GATEWAY= value in interface files which have a gateway in the subnet configuration. LP: #1686856
2017-07-17Scaleway: add datasource with user and vendor data for Scaleway.Julien Castets
Here we add and enable by default a datasource for Scaleway cloud. The datasource quickly exits unless one of three things: a.) 'Scaleway' found as the system vendor b.) 'scaleway' found on the kernel command line. c.) the directory /var/run/scaleway exists (this is currently created by the scaleway initramfs module). One interesting bit of this particular datasource is that it requires the source port of the http request to be < 1024.
2017-07-17Support comments in content read by load_shell_content.Scott Moser
load_shell_content previously would not allow shell comment characters in the content being parsed. If comments=True is not passed then an exception would previously be raised as the line would not be guaranteed to have an '=' in it.
2017-07-11write_files: Remove log from helper function signatures.Andrew Jorgensen
Instead of passing around a 'log' reference to functions, just import logging and use that. This is the pattern that is now more common in cloud-init.
2017-06-29read_dmi_data: always return None when inside a container.Scott Moser
This fixes stacktrace and warning message that would be printed to the log if running inside a container and read_dmi_data tried to access a key that was not present. In a container, the /sys/class/dmi/id data is not relevant to the but to the host. Additionally an unpriviledged container might see strange behavior: # cd /sys/class/dmi/id/ # id -u 0 # ls -l chassis_serial -r-------- 1 nobody nogroup 4096 Jun 29 16:49 chassis_serial # cat chassis_serial cat: /sys/class/dmi/id/chassis_serial: Permission denied The solution here is to just always return None when running in a container. LP: #1701325
2017-06-27Azure: Add network-config, Refactor net layer to handle duplicate macs.Ryan Harper
On systems with network devices with duplicate mac addresses, cloud-init will fail to rename the devices according to the specified network configuration. Refactor net layer to search by device driver and device id if available. Azure systems may have duplicate mac addresses by design. Update Azure datasource to run at init-local time and let Azure datasource generate a fallback networking config to handle advanced networking configurations. Lastly, add a 'setup' method to the datasources that is called before userdata/vendordata is processed but after networking is up. That is used here on Azure to interact with the 'fabric'.
2017-06-15FreeBSD: Make freebsd a variant, fix unittests and tools/build-on-freebsd.Scott Moser
- Simplify the logic of 'variant' in util.system_info much of the data from https://github.com/hpcugent/easybuild/wiki/OS_flavor_name_version - fix get_resource_disk_on_freebsd when running on a system without an Azure resource disk. - fix tools/build-on-freebsd to replace oauth with oauthlib and add bash which is a dependency for tests. - update a fiew places that were checking for freebsd but not using the util.is_FreeBSD()
2017-06-15FreeBSD: fix test failureScott Moser
The previous commit caused test failure. This separates out _check_freebsd_cdrom and mocks it in a test rather than patching open.
2017-06-15FreeBSD: replace ifdown/ifup with "ifconfig down" and "ifconfig up".Hongjiang Zhang
Fix the issue caused by different commands on Linux and FreeBSD. On Linux, we used ifdown and ifup to enable and disable a NIC, but on FreeBSD, the counterpart is "ifconfig down" and "ifconfig up". LP: #1697815
2017-06-15FreeBSD: fix cdrom mounting failure if /mnt/cdrom/secure did not exist.Hongjiang Zhang
The current method is to attempt to mount the cdrom (/dev/cd0), if it is successful, /dev/cd0 is configured, otherwise, it is not configured. The problem is it forgets to check whether the mounting destination folder is created or not. As a result, mounting attempt failed even if cdrom is ready. LP: #1696295
2017-06-15main: Don't use templater to format the welcome messageAndrew Jorgensen
Some versions of Cheetah returned everything as unicode by default (not utf-8 or ascii) and some varieties of syslog would choke on unicode. Jinja2 is probably fine, but Python's format() is perfectly adequate for a short message like the welcome message.

2017-06-15write_file(s): Print permissions as octal, not decimalAndrew Jorgensen
Unix file modes are usually represented as octal, but they were being interpreted as decimal, for example 0o644 would be printed as '420'. Reviewed-by: Tom Kirchner <tjk@amazon.com>
2017-06-12selinux: Allow restorecon to be non-fatal.Ryan Harper
On some systems with python-libselinux a bug[1] related to recursive restorecon fails but the distro release does not yet include an update. This change will accept the error and log a warning. 1. https://bugzilla.redhat.com/show_bug.cgi?id=1406520 LP: #1686751
2017-06-12net: Allow netinfo subprocesses to return 0 or 1.Ryan Harper
On systems with selinux enabled, some of the networking commands executed successfully do not return 0. Allow these commands to return 1 since the output is valid. Ultimately we need to get this information in some way so that we can display it correctly. For now, work around the stack trace when selinux does not allow us to collect it. LP: #1686751
2017-06-12net: Allow for NetworkManager configurationRyan McCabe
In cases where the config json specifies nameserver entries, if there are interfaces configured to use dhcp, NetworkManager, if enabled, will clobber the /etc/resolv.conf that cloud-init has produced, which can break dns. If there are no interfaces configured to use dhcp, NetworkManager could clobber /etc/resolv.conf with an empty file. This patch adds a mechanism for dropping additional configuration into /etc/NetworkManager/conf.d/ and disables management of /etc/resolv.conf by NetworkManager when nameserver information is provided in the config.

2017-06-08net: normalize data in network_state objectScott Moser
The network_state object's network and route keys would have different information depending upon how the network_state object was populated. This change cleans that up. Now: * address will always contain an IP address. * prefix will always include an integer value that is the network_prefix for the address. * netmask will be present only if the address is ipv4, and its value will always correlate to the 'prefix'.
2017-06-08Chef: Update omnibus url to chef.io, minor doc changes.JJ Asghar

2017-06-08rhel/centos spec cleanups.Scott Moser
Many changes here to get us able to build rpms on CentOS 5 or 6 and RHEL. * add 'Requires' as 'BuildRequires' also. This allows us to run cloud-init tools in the build environment, and also will allow us to run tests in the build process. * build for both systemd and upstart (centos 5) init systems. * Add 'centos' as a variant Adding the variant means we can use the 'centos' user as default on centos rather than a 'fedora' or 'rhel'. * drop argparse from the requirements. On any system other than python 2.6, having a 'requirements' that mentions argparse just causes problems. Instead we add that Requires to the spec directly. * list dependency on dmidecode (as redhat distro spec had) * remove duplicate line in files section ({_unitdir}/cloud-*) * Use rpm macros for init-system chunks and drop use of init_system variable template * Add el6 only build-req on python-argparse * python-cheetah is not required in the build environment as the the spec is already rendered. (We will soon move the spec to jinja).
2017-06-08cloud.cfg: move to a template. setup.py changes along the way.Scott Moser
Here we move the config/cloud.cfg to be rendered as a template. That allows us to maintain deltas between distros in one place. Currently we use 'variant' variable to make decisions. A tools/render-cloudcfg is provided to render the file. There were changes to setup.py, MANIFEST.in to allow us to put all files into a virtual env installation and to render the cloud-config file in 'install' or 'bdist' targets. We have also included some config changes that were found in the redhat distro spec. * include some config changes from the redhat distro spec. The rendered cloud.cfg has some differences. Ubuntu: white space and comment changes only. Freebsd: - whitespace changes and comment changes - datasource_list definition moved to be closer to 'datasource'. - enable modules: migrator, write_files - move package-update-upgrade-install to final. The initial work was done by Josh Harlow.
2017-06-07RHEL/CentOS: Fix default routes for IPv4/IPv6 configuration.Andreas Karis
Since f38fa413176, default routes get added to both ifcfg-* and route-* and route6-* files. Default routes should only go to ifcfg-* files, otherwise the information is redundant. LP: #1696176
2017-06-06NoCloud: support seed of nocloud from smbios informationVladimir Pouzanov
This allows the user to seed NoCloud in a trivial way from qemu/libvirt, by using a stock image and passing a single command line flag. No custom command line, no filesystem modification, no bootstrap disk image. This is particularly handy now that Ec2 backend is discouraged from use under bug 1660385. LP: #1691772
2017-06-06net: when selecting a network device, use natural sort orderMarc-Aurèle Brothier
The code deciding which interface to choose as the default to request the IP address through DHCP does not sort the interfaces correctly. On Ubuntu Xenial images for example, the interfaces are named ens1, ens2, ens3..., ens11, ... depending on the pci bus address. The python sorting will list 'ens11' before 'ens3' for example despite the fact that 'ens3' should be before 'ens11'. This patch address this issue and sort the interface names according to a human sorting. Signed-off-by: Marc-Aurèle Brothier <m@brothier.org>
2017-06-01azure: remove accidental duplicate line in merge.Scott Moser
In previous commit I inadvertantly left two calls to asset_tag = util.read_dmi_data('chassis-asset-tag') The second did not do anything useful. Thus, remove it.
2017-06-01azure: identify platform by well known value in chassis asset tag.Chad Smith
Azure sets a known chassis asset tag to 7783-7084-3265-9085-8269-3286-77. We can inspect this in both ds-identify and DataSource.get_data to determine whether we are on Azure. Added unit tests to cover these changes and some minor tweaks to Exception error message content to give more context on malformed or missing ovf-env.xml files. LP: #1693939
2017-05-31ntp: Add schema definition and passive schema validation.Chad Smith
cloud-config files are very flexible and permissive. This adds a jsonsschema definition to the cc_ntp module and validation functions in cloudinit/config/schema which will log warnings about invalid configuration values in the ntp section. A cmdline tools/cloudconfig-schema is added which can be used in our dev environments to quickly attempt to exercise the ntp schema. It is also exposed as a main in cloudinit.config.schema. (python3 -m cloudinit.config.schema) LP: #1692916
2017-05-31Fix eni rendering for bridge params that require repeated key for values.Ryan Harper
There are a few bridge parameters which require repeating the key with each value in the list when rendering eni. Extend the network unittests to cover all of the known bridge parameters and check we render eni and netplan correctly.
2017-05-31net: remove systemd link file writing from eni rendererRyan Harper
During the network v2 merge, we inadvertently re-enabled rendering systemd .link files. This files are not required as cloud-init already has to do interface renaming due to issues with udevd which may refuse to rename certain interfaces (such as veth devices in a LXD container). As such, removing the code altogether.

That is now fixed to '104.130.20.155/24' Also fixed is reading of a route that had a network prefix integer in the 'netmask' rather than a netmask. LP: #1689346 LP: #1684349
2017-05-26disk_setup: udev settle before attempting partitioning or fs creation.Scott Moser

2017-05-24cc_ntp: Restructure cc_ntp unit tests.Chad Smith
Any CiTestCase subclass can now set a class attribute with_logs = True and tests can now make assertions on self.logs.getvalue(). This branch restructures a bit of cc_ntp module to get better test coverage of the module. It also restructures the handler_cc_ntp unit tests to avoid nested mocks where possible. Deeply nested mocks cause a couple of issues: - greater risk: mocks are permanent within the scope, so multiple call-sites could be affected by package mocks - less legible tests: each mock doesn't advertise the actual call-site - tight coupling: the unit test logic to tightly bound to the actual implementation in remote (unrelated) modules which makes it more costly to maintain code - false success: we should be testing the expected behavior not specific remote method names as we want to know if that underlying behavior changes and breaks us.

2017-05-22disk_setup: fix several issues with gpt disk partitions.Scott Moser
This fixes several shortcomings of disk_setup with gpt disks. * 'sgdisk -p' was being used to determine the size of a disk. this can fail if it believes there is a bad gpt partition table. Instead we just use blockdev now for both mbr or gpt disks. * parsing of sgdisk -p output assumed that the 'name' of the partition type would not have any spaces (Microsoft basic data) * interaction with sgdisk did not realize that sgdisk wants input of '8300' rather than '83' and will output the same. LP: #1692087
2017-05-22tox: move pylint target to 1.7.1Scott Moser
The motivation for this is to make tip-pylint target green. It does 2 things: a.) silence a warning that is generated in pylint 1.7.1, but not other versions of pylint. This bug in pylint is filed at https://github.com/PyCQA/pylint/issues/1444 b.) move tox -e pylint to use pylint 1.7.1
2017-05-22Fix get_interfaces_by_mac for empty macsScott Moser
Some interfaces (greptap0 in the bug) have a mac address of '00:00:00:00:00:00'. That was causing a duplicate mac detection as the 'lo' device also has that mac. The change here is to just ignore macs other than 'lo' that have that. LP: #1692028
2017-05-19DigitalOcean: remove routes except for the public interface.Ben Howard
Previously, the datasource for DigitalOcean allowed for a gateway on each NIC. As a result, on Ubuntu 16.04, networking.service was broken.

DigitalOcean is looking at changing the meta-data, however, this will result in another version of the meta-data JSON. LP: #1681531.
