2020-11-23Ability to hot-attach NICs to preprovisioned VMs before reprovisioning (#613)aswinrajamannar
Adds the ability to run the Azure preprovisioned VMs as NIC-less and then hot-attach them when assigned for reprovision. The NIC on the preprovisioned VM is hot-detached as soon as it reports ready and goes into wait for one or more interfaces to be hot-attached. Once they are attached, cloud-init gets the expected number of NICs (in case there are more than one) that will be attached from IMDS and waits until all of them are attached. After all the NICs are attached, reprovision proceeds as usual.
2020-11-19cc_resizefs on FreeBSD: Fix _can_skip_ufs_resize (#655)Mina Galić
On FreeBSD, if a UFS has trim: (-t) or MAC multilabel: (-l) flag, resize FS fail, because the _can_skip_ufs_resize check gets tripped up by the missing options. This was reported at FreeBSD Bugzilla: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250496 and as LP: #1901958 Rather than fixing the parser as in the patches proposed there (and attempted in #636) this pull-request rips out all of it, and simplifies the code. We now use `growfs -N` and check if that returns an error. If it returns the correct kind of error, we can skip the resize, because we either are at the correct size, or the filesystem in question is broken or not UFS. If it returns the wrong kind of error, we just re-raise it. LP: #1901958

Pushing dmesg log to KVP to help troubleshoot VM boot issues
2020-11-18DataSourceAzure: update password for defuser if exists (#671)Anh Vo
cc_set_password will only update the password for the default user if cfg['password'] is set. The existing code of datasource Azure will fail to update the default user's password because it does not set that metadata. If the default user doesn't exist in the image, the current code works fine because the password is set during user create and not in cc_set_password
2020-11-18Azure helper: Increase Azure Endpoint HTTP retries (#619)Johnson Shi
Increase Azure Endpoint HTTP retries to handle occasional platform network blips. Introduce a common method http_with_retries in the azure.py helper, which will serve as the common HTTP request handler for all HTTP requests with the Azure endpoint. This method has builtin retries and reporting diagnostics logic.
2020-11-18DataSourceAzure: send failure signal on Azure datasource failure (#594)Johnson Shi
On systems where the Azure datasource is a viable platform for crawling metadata, cloud-init occasionally encounters fatal irrecoverable errors during the crawling of the Azure datasource. When this happens, cloud-init crashes, and Azure VM provisioning would fail. However, instead of failing immediately, the user will continue seeing provisioning for a long time until it times out with "OS Provisioning Timed Out" message. In these situations, cloud-init should report failure to the Azure datasource endpoint indicating provisioning failure. The user will immediately see provisioning terminate, giving them a much better failure experience instead of pointlessly waiting for OS provisioning timeout.
2020-11-18cli: add --system param to allow validating system user-data on a machine (#575)Chad Smith
Allow root user to validate the userdata provided to the launched machine using `cloud-init devel schema --system`
2020-11-09Make wakeonlan Network Config v2 setting actually work (#626)dermotbradley
Add code so that specifying "wakeonlan: true" actually results in relevant configuration entry appearing in /etc/network/interfaces, Netplan, and sysconfig for RHEL and OpenSuse. Add testcases for the above.
2020-11-06replace usage of dmidecode with kenv on FreeBSD (#621)Mina Galić
FreeBSD lets us read out kernel parameters with kenv(1), a user-space utility that's shipped in "base" We can use it in place of dmidecode(8), thus removing the dependency on sysutils/dmidecode, and the restrictions to i386 and x86_64 architectures that this utility imposes on FreeBSD.

2020-11-04azure: enable pushing the log to KVP from the last pushed byte (#614)Moustafa Moustafa
This allows the cloud-init log to be pushed multiple times during boot, with the latest lines being pushed each time.
2020-11-04split read_fs_info into linux & freebsd parts (#625)Mina Galić
FreeBSD doesn't have blkid, so we want to use geom to list devices and their fstypes and labels. This PR also adds `jail` to the list of is_container() And we now also properly cache geom and blkid output! A test is added to verify the new behaviour by correctly identifying NoCloud on FreeBSD. Co-authored-by: Scott Moser <smoser@brickies.net>
2020-11-02cloudinit: move dmi functions out of util (#622)Scott Moser
This just separates the reading of dmi values into its own file. Some things of note: * left import of util in dmi.py only for 'is_container' It'd be good if is_container was not in util. * just the use of 'util.is_x86' to dmi.py * open() is used directly rather than load_file.
2020-10-30Hetzner: Fix instance_id / SMBIOS serial comparison (#640)Markus Schade
Fixes erroneous string/int comparison introduced in 1431c8a metadata['instance-id'] is an integer but the value read from smbios is a string. The comparision would cause TypeError.
2020-10-29Hetzner: initialize instance_id from system-serial-number (#630)Markus Schade
Hetzner Cloud also provides the instance ID in SMBIOS information. Use it to locally check_instance_id and to compared with instance_id from metadata service. LP: #1885527
2020-10-29Explicit set IPV6_AUTOCONF and IPV6_FORCE_ACCEPT_RA on static6 (#634)Eduardo Otubo
The static and static6 subnet types for network_data.json were being ignored by the Openstack handler, this would cause the code to break and not function properly. As of today, if a static6 configuration is chosen, the interface will still eventually be available to receive router advertisements or be set from NetworkManager to wait for them and cycle the interface in negative case. It is safe to assume that if the interface is manually configured to use static ipv6 address, there's no need to wait for router advertisements. This patch will set automatically IPV6_AUTOCONF and IPV6_FORCE_ACCEPT_RA both to "no" in this case. This patch fixes the specific behavior only for RHEL flavor and sysconfig renderer. It also introduces new unit tests for the specific case as well as adjusts some existent tests to be compatible with the new options. This patch also addresses this problem by assigning the appropriate subnet type for each case on the openstack handler. rhbz: #1889635 rhbz: #1889635 Signed-off-by: Eduardo Otubo otubo@redhat.com
2020-10-28Add config modules for controlling IBM PowerVM RMC. (#584)Aman306
Reliable Scalable Cluster Technology (RSCT) is a set of software components that together provide a comprehensive clustering environment(RAS features) for IBM PowerVM based virtual machines. RSCT includes the Resource Monitoring and Control (RMC) subsystem. RMC is a generalized framework used for managing, monitoring, and manipulating resources. RMC runs as a daemon process on individual machines and needs creation of unique node id and restarts during VM boot. LP: #1895979 Co-authored-by: Scott Moser <smoser@brickies.net>

2020-10-27gentoo: fix hostname rendering when value has a comment (#611)Manuel Aguilera
Gentoo's hostname file format instead of being just the host name is hostname=thename". The old code works fine when the file has no comments but if there is a comment the line ``` gentoo_hostname_config = 'hostname="%s"' % conf ``` can render an invalid hostname file that looks similar to ``` hostname="#This is the host namehello" ``` The fix inserts the hostname in a gentoo friendly way so that it gets handled by HostnameConf as a whole and comments are handled and preserved
2020-10-21Drop vestigial update_resolve_conf_file function (#620)Scott Moser
update_resolve_conf_file is no longer used. The last reference to it was removed in c3680475f9c970, which was itself a "remove dead code" commit.
2020-10-20ssh_util: handle non-default AuthorizedKeysFile config (#586)Eduardo Otubo
The following commit merged all ssh keys into a default user file `~/.ssh/authorized_keys` in sshd_config had multiple files configured for AuthorizedKeysFile: commit f1094b1a539044c0193165a41501480de0f8df14 Author: Eduardo Otubo <otubo@redhat.com> Date: Thu Dec 5 17:37:35 2019 +0100 Multiple file fix for AuthorizedKeysFile config (#60) This commit ignored the case when sshd_config would have a single file for AuthorizedKeysFile, but a non default configuration, for example `~/.ssh/authorized_keys_foobar`. In this case cloud-init would grab all keys from this file and write a new one, the default `~/.ssh/authorized_keys` causing the bug. rhbz: #1862967 Signed-off-by: Eduardo Otubo <otubo@redhat.com>
2020-10-16DataSourceAzure: write marker file after report ready in preprovisioning (#590)Johnson Shi
DataSourceAzure previously writes the preprovisioning reported ready marker file before it goes through the report ready workflow. On certain VM instances, the marker file is successfully written but then reporting ready fails. Upon rare VM reboots by the platform, cloud-init sees that the report ready marker file already exists. The existence of this marker file tells cloud-init not to report ready again (because it mistakenly assumes that it already reported ready in preprovisioning). In this scenario, cloud-init instead erroneously takes the reprovisioning workflow instead of reporting ready again.
2020-10-15openstack: consider product_name as valid chassis tag (#580)Adrian Vladu
Consider valid product names as valid chassis asset tags when detecting OpenStack platform before crawling for OpenStack metadata. As `ds-identify` tool uses product name as valid chassis asset tags, let's replicate the behaviour in the OpenStack platform detection too. This change should be backwards compatible and a temporary fix for the current limitations on the OpenStack platform detection. LP: #1895976

2020-10-13net: add the ability to blacklist network interfaces based on driver during ↵Anh Vo
enumeration of physical network devices (#591)
2020-09-24Azure parse_network_config uses fallback cfg when generate IMDS network cfg ↵Johnson Shi
fails (#549) Azure datasource's `parse_network_config` throws a fatal uncaught exception when an exception is raised during generation of network config from IMDS metadata. This happens when IMDS metadata is invalid/corrupted (such as when it is missing network or interface metadata). This causes the rest of provisioning to fail. This changes `parse_network_config` to be a non-fatal implementation. Additionally, when generating network config from IMDS metadata fails, fall back on generating fallback network config (`_generate_network_config_from_fallback_config`). This also changes fallback network config generation (`_generate_network_config_from_fallback_config`) to blacklist an additional driver: `mlx5_core`.

2020-09-15create a shutdown_command method in distro classes (#567)Emmanuel Thomé
Under FreeBSD, we want to use "shutdown -p" for poweroff. Alpine Linux also has some specificities. We choose to define a method that returns the shutdown command line to use, rather than a method that actually does the shutdown. This makes it easier to have the tests in test_handler_power_state do their verifications. Two tests are added for the special behaviours that are known so far.
2020-09-15network: Fix type and respect name when rendering vlan in sysconfig. (#541)Eduardo Otubo
Prior to this change, vlans were rendered in sysconfig with 'TYPE=Ethernet', and incorrectly rendered the PHYSDEV based on the name of the vlan device rather than the 'link' provided in the network config. The change here fixes: * rendering of TYPE=Ethernet for a vlan * adds a warning if the configured device name is not supported per the RHEL 7 docs "11.5. Naming Scheme for VLAN Interfaces" LP: #1788915 LP: #1826608 RHBZ: #1861871

2020-08-24Azure: Add netplan driver filter when using hv_netvsc driver (#539)James Falcon
This fixes a long delay during boot of some instances. For Azure instance types using SR-IOV via the Hyper-V netvsc network driver, two network interfaces are created that share the same MAC, but only the virtual device should be configured and used. Updating the netplan configuration to filter on the hv_netvsc driver prevents netplan from trying to figure both devices. LP: #1830740

2020-08-20Pushing cloud-init log to the KVP (#529)Moustafa Moustafa
Push the cloud-init.log file (Up to 500KB at once) to the KVP before reporting ready to the Azure platform. Based on the analysis done on a large sample of cloud-init.log files, Here's the statistics collected on the log file size: P50 P90 P95 P99 P99.9 P99.99 137K 423K 537K 3.5MB 6MB 16MB This change limits the size of cloud-init.log file data that gets dumped to KVP to 500KB. So for ~95% of the cases, the whole log file will be dumped and for the remaining ~5%, we will get the last 500KB of the cloud-init.log file. To asses the performance of the 500KB limit, 250 VM were deployed with a 500KB cloud-init.log file and the time taken to compress, encode and dump the entries to KVP was measured. Here's the time in milliseconds percentiles: P50 P99 P999 75.705 232.701 1169.636 Another 250 VMs were deployed with this logic dumping their normal cloud-init.log file to KVP, the same timing was measured as above. Here's the time in milliseconds percentiles: P50 P99 P999 1.88 5.277 6.992 Added excluded_handlers to the report_event function to be able to opt-out from reporting the events of the compressed cloud-init.log file to the cloud-init.log file. The KVP break_down logic had a bug, where it will reuse the same key for all the split chunks of KVP which results in overwriting the split KVPs by the last one when consumed by Hyper-V. I added the split chunk index as a differentiator to the KVP key. The Hyper-V consumes the KVPs from the KVP file as chunks whose key is 512KB and value is 2048KB but the Azure platform expects the value to be 1024KB, thus I introduced the Azure value limit.

According to man page `man 8 swapon', "Preallocated swap files are supported on XFS since Linux 4.18". This patch checks for kernel version before attepting to create swapfile, using dd for XFS only on kernel versions <= 4.18 or btrfs.

DataSourceAzure: Gracefully handle the case of set hostname failure during provisioning
2020-07-21VMware: Support parsing DEFAULT-RUN-POST-CUST-SCRIPT (#441)xiaofengw-vmware
Add support for VMware's vCD configuration setting DEFAULT-RUN-POST-CUST-SCRIPT. When set True, it will default vms to run post customization scripts if the VM has not been configured in VMTools with "enable-custom-scripts" set False. Add datasource documentation with a bit more context about this interaction on VMware products. With this fix, the behavior will be: * If VM administrator doesn't want others to execute a script on this VM, VMtools can set "enable-custom-scripts" to false from the utility "vmware-toolbox-cmd". * If VM administrator doesn't set value to "enable-custom-scripts", then by default this script is disabled for security purpose. * For VMware's vCD product , the preference is to enable the script if "enable-custom-scripts" is not set. vCD will generate a configuration file with "DEFAULT-RUN-POST-CUST-SCRIPT" set to true. This flag works for both VMware customization engine and cloud-init.
2020-07-15cc_ca_certs.py: fix blank line problem when removing CAs and adding new one ↵dermotbradley
(#483) Problem: When cc_ca_certs configuration has both "remove-defaults: true" and also specifies one, or more, new trusted CAs to add then the resultant /etc/ca-certificates.conf file's 1st line is blank. As noted in comments in the existing cc_ca_certs.py code blank lines in this file cause problems. Fix: Before adding the cloud-init CA filename to this file first check the size of the file - if is is empty (as all existing CAs have been deleted) then write only the cloud-init CA filename to the file rather than appending it to the file.
