Author: rodrigc Date: Mon Nov 25 20:33:33 2013 New Revision: 258591 URL: http://svnweb.freebsd.org/changeset/base/258591 Log: In vnet_route_uninit(), free some memory that is allocated in vnet_route_init(). To reproduce the problem: (1) Take a GENERIC kernel config, and add options for: VIMAGE, WITNESS, INVARIANTS. (2) Run this command in a loop: jail -l -u root -c path=/ name=foo persist vnet && jexec foo ifconfig lo0 127.0.0.1/8 && jail -r foo see: http://lists.freebsd.org/pipermail/freebsd-current/2010-November/021280.html http://lists.freebsd.org/pipermail/freebsd-current/2010-November/021291.html This doesn't eliminate all the "Freed UMA keg was not empty" warning messages on the console, but it helps.
