I am use ipfilter 3.2.9 compiled in kernel.
But problem is in inserting current entry `so_list' in `so' at
uipc_socket2.c:230:
TAILQ_INSERT_TAIL(&head->so_incomp, so, so_list);
this is in queue.h:343
#define TAILQ_INSERT_TAIL(head, elm, field) do { \
(elm)->field.tqe_next = NULL; \
(elm)->field.tqe_prev = (head)->tqh_last; \
*(head)->tqh_last = (elm); \
(head)->tqh_last = &(elm)->field.tqe_next; \
} while (0)
Can anyone help me?
