conntrackd: generalize file descriptor infrastructure
This patch generalizes the select-based file descriptor infrastructure by allowing you to register file descriptors and its callbacks. Instead of hardcoding the descriptors that needs to be checked. Now, struct fds_item contains a callback and pointer to data that is passed to it: struct fds_item { struct list_head head; int fd; + void (*cb)(void *data); + void *data; }; Then, we check which ones are active in the select_main_step() function: list_for_each_entry(cur, &STATE(fds)->list, head) { if (FD_ISSET(cur->fd, &readfds)) cur->cb(cur->data); } And it invoked the corresponding callback. I had to slightly modify the channel infrastructure to fit it into the changes. This modularity is required for the upcoming cthelper support. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
