Hello,
This is a request to please backport this patch from the 1.4.1 agent:
https://github.com/WindowsAzure/WALinuxAgent/commit/375f1ede38fd323c2560e7e21ba99ac50bc66acd
Summary
The Ubuntu images in the Windows Azure gallery (except for 12.10) all use cloud-init for provisioning. This means that WALA provisioning and the hostname monitor are disabled via /etc/waagent.conf.
However, when a user runs 'waagent -deprovision' the agent will attempt to modify the 'send host-name' parameter dhclient.conf file to set the hostname to "localhost.localdomain". But with provisioning and the monitor disabled, the agent does not have a chance to reset this parameter to the proper hostname. So captured Ubuntu images will not register their correct DNS name with the DHCP server.
In the Ubuntu images this behavior is not necessary since dhclient is already configured to send its hostname to the DHCP server. This patch makes the agent a bit smarter about this and leaves dhclient.conf alone if it sees that it is already configured to send it's current hostname to the DHCP server. |
SRU justification
Impact : Users who run "waagent --deprovision" and then capture/snapshot an image will not have the instance register with iDNS and subsiquently the instance will be unreachable.
This issue is caused by waagent changing the "send-hostname" parameter in the dhclient.
Fix : Applied upstream commit from https://github.com/WindowsAzure/WALinuxAgent/commit/375f1ede38fd323c2560e7e21ba99ac50bc66acd
Test Case :
- Launch instance
- Install walinuxagent from proposed
- Run "waagent --deprovision"
- Shutdown instance
- Run "azure vm shutdown <name>" with Azure CLI tool
- Run "azure vm capture <name> <new name>" with Azure CLI tool
- Launch new instance from <new name>
- Confirm that instance is accesable using DNS name
Regression : Low. The change fixes how waagent interacts with /etc/dhcp/dhcpclient.conf. If an instance has been configured via cloud-init, there is no change.
