Magical Mystery Tour through VMap, vaddrs.conf. #6

jkew · 2013-02-28T11:07:19Z

CLEANUP: Virtual IPs were once managed such that within a cluster they
would automatically rebalance themselves between nodes by bringing
subinterfaces up and down. After ATS was open sourced the original
setuid tool, vip_config (or traffic_vip_config) was inadvertently
removed; but the code which depended on this tool was not cleaned
up.

   Since modern deployments either do not use this tool at all
   (because it was broken for a few years) and modern deployments also
   have some central system for managing cluster state reliably, we
   do not need VMap to implement some scheme for automatically
   rebalancing the ips.

   This CL keeps much of the code for detecting ip address conflicts
   and for receiving the multicast messages from the cluster; but we
   remove all instances where we either bring up/down an interface.

   Deployments should manage this through external state systems.

   Note: VIPs do not actually bind to the specific addresses in
   vaddrs; this is just an operations convience to ensure that a
   cluster has no ip conflicts or unmanaged vips.

   Note: The *right* thing to do here may be to recall that old tool and let
   VMap do it's thing.

   Note: Another *right* thing to do may be to remove VMap entirely, along
   with the associated cluster messages. At least with this exiting changeset
   we can detect ip address conflicts.

To be clear; as long as VMap does not actually bind to those addresses; I'm not dependent on VMap at all. This was sort of a long deep dive into one part of the code which was a little confusing from the configuration files.

ASan reports a leak concerning the ImageMagick library for plugins that link against it. The leak is associated with the ImageMagick library itself as commenting everything out from the ATS plugin, leaving a bare TSPluginInit, still results in the leak report. This patch suppresses the leak report for the library we do not own and for a leak that has not been seen to be any larger than the initialization bytes associated with the library. Here's the leak report this suppression file addresses: ================================================================= ==18362==ERROR: LeakSanitizer: detected memory leaks Direct leak of 96 byte(s)

ASan reported a use-after-free in Do_upstream_rsp_body.
