[Bug 1488896] [NEW] WALinuxAgentShim fails to handle colons in packed values in dhclient.eth0.leases

 

Public bug reported:

We currently assume that a single colon in the unknown-245 dhclient key
indicates we are dealing with hex; this is not necessarily true. If any
part of the IP address is '58', then a colon will be included in the
packed values.

We should have more robust determination of if we're dealing with a hex
string.

** Affects: cloud-init
