[Bug 1189571] Re: [SRU] "Unable to set up timer: out of range" caused by bad 64_bit timer

[Brian Murray]

Hello Ben, or anyone else affected,

Accepted isc-dhcp into raring-proposed. The package will build now and
be available at http://launchpad.net/ubuntu/+source/isc-
dhcp/4.2.4-5ubuntu2.1 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  SRU justification

  [Symtpom]:The dchp client on 12.10 and 13.04 on 64-bit installations
  fails with "Unable to set up timer: out of range" and then exits when
  the max lease time is given (~135years).

  [Impact]: Systems running on networks with max lease times will not
  configure and the dhcpclient will error out and exit.

  [Test Case]:
  - Set DHCP Server to serve out max lease times
  - Configure Ubuntu to use DHCP
  - Run "sudo restart networking"
  - Check if dhclient is NOT running, i.e. "ps axw  | grep dhclient"
  - Install new isc-dhcp-client and isc-dhcp-common package
  - Run "sudo restart networking"
  - Check if dhclient IS running, i.e. "ps axw | grep dhclient"

  [Regression]: No regressions are expected. This fix simply reduces the
  lease time to (MAX_TIME - 9) seconds in cases where the lease exceeds
  the max lease.

  [Other Info]
  This is an upstream regression between 4.1.ESV-R4 (precise's isc-dhcp) and 4.2.4 (quantal, raring, saucy). It was fixed in Fedora under redhat bug 789601 (http://pkgs.fedoraproject.org/cgit/dhcp.git/commit/?id=bd413ec3f9585ff8ccb8a5a66097fab53a8f5fe4)

  [Originial Report]: 
  On Windows Azure, the max lease time is used. In digging, it appears
  that the problem is related to the large lease times:

  From /var/log/upstart/netwokring:
  Listening on LPF/eth0/00:15:5d:52:cd:db
  Sending on   LPF/eth0/00:15:5d:52:cd:db

  DHCPACK of 100.86.20.3 from 100.86.20.1
  RTNETLINK answers: File exists
  Unable to set up timer: out of range
  Failed to bring up eth0.

  This looks like a duplicate of the RH Bug 789601
