** Description changed: - DHCPDISCOVER on eth2 to 255.255.255.255 port 67 interval 3 (xid=0x7e777c23) + SRU Justification + + Impact: The Cloud Sigma Datasource read and writes to /dev/ttyS1 if + present; the Datasource does not have a time out. On non-CloudSigma + Clouds or systems w/ /dev/ttyS1, Cloud-init will block pending a + response, which may never come. Further, it is dangerous for a default + datasource to write blindly on a serial console as other control plane + software and Clouds use /dev/ttyS1 for communication. + + Fix: The patch disables Cloud Sigma by default. + + Verification: + 1. Purge Cloud-init + 2. Install from -proposed + 3. Look in /etc/cloud/cloud.d/90_dpkg.cfg, and confirm CloudSigma is not in the list of datasources. + + Regression: The risk is low, except on CloudSigma targets which try to + use new images generated with the new Cloud-init version. + + + [Original Report] + DHCPDISCOVER on eth2 to 255.255.255.255 port 67 interval 3 (xid=0x7e777c23) DHCPREQUEST of 10.22.157.186 on eth2 to 255.255.255.255 port 67 (xid=0x7e777c23) - DHCPOFFER of 10.22.157.186 from 10.22.157.149 - DHCPACK of 10.22.157.186 from 10.22.157.149 - bound to 10.22.157.186 -- renewal in 39589 seconds. - * Starting Mount network filesystems [ OK ] - * Starting configure network device [ OK ] - * Stopping Mount network filesystems [ OK ] - * Stopping DHCP any connected, but unconfigured network interfaces [ OK ] - * Starting configure network device [ OK ] - * Stopping DHCP any connected, but unconfigured network interfaces [ OK ] - * Starting configure network device [ OK ] + DHCPOFFER of 10.22.157.186 from 10.22.157.149 + DHCPACK of 10.22.157.186 from 10.22.157.149 + bound to 10.22.157.186 -- renewal in 39589 seconds. + * Starting Mount network filesystems [ OK ] + * Starting configure network device [ OK ] + * Stopping Mount network filesystems [ OK ] + * Stopping DHCP any connected, but unconfigured network interfaces [ OK ] + * Starting configure network device [ OK ] + * Stopping DHCP any connected, but unconfigured network interfaces [ OK ] + * Starting configure network device [ OK ] And it stops there. I see this on about 10% of deploys.
