Networking change causes distribution headaches

I can only assume that the Ubuntu release team thought this through and have the ability to push an update out that reverts the quick fix when a proper fix is available and tested.

If there are security implications for turning timestamping off, then intrepid Intrepid users should probably impress on the Ubuntu devs the importance of turning timestamping on as an update as soon as possible to limit exposure...in the appropriate Ubuntu communications channel.

I'm not going to falsely stand myself up as a network security expert and make a judgement on the validity of the security concern. Even if the security implications are a valid concern, I think its reasonable for Ubuntu to use the option of having a release day update available instead of having to restart their release process to incorporate the upstream fix. As long as a release day update addresses the security implications by turning timestamping back on and integrates the proper kernel patch for the routing regression, the exposure is mitigated to the level of any security issue which requires a post release update.
