This bug has been copied from bug #590783 and has been proposed to be backported to 5.5 z-stream (EUS).
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: When dumping the pfkey database the kernel used to return only part of the database due to the small socket buffer size. When racoon was deployed on a system with a large number of network security policy entries, the racoon coould not find all of the security policy entries in the database. The updated package supports a new configuration option pfkey_buffer to the racoon.conf file that allows to set the buffer size as appropriate for the deployment requirements.
