Fixed In Version: kernel-2.6.32-71.12.1.el6
Doc Type: Bug Fix
Doc Text:
When configuring an SIT (Simple Internet Transition) tunnel while a remote address is configured, kernel panic occurred, caused by an execution of a NULL header_ops pointer in the neigh_update_hhs() function. With this update, a check is introduced that makes sure the header_ops pointer is not of the value NULL, thus, kernel panic no longer occurs.
