netlbl_calipso_add_pass()\n\nIf IPv6 support is disabled at boot (ipv6.disable=1),\nthe calipso_init() -\u003e netlbl_calipso_ops_register() function isn't called,\nand the netlbl_calipso_ops_get() function always returns NULL.\nIn this case, the netlbl_calipso_add_pass() function allocates memory\nfor the doi_def variable but doesn't free it with the calipso_doi_free().\n\nBUG: memory
