In the splnet times, netgraph was functional and synchronous. Nowadays, 2005-07-05T17:35:20Z Gleb Smirnoff glebius@FreeBSD.org 2005-07-05T17:35:20Z urn:sha1:8afe16d57ba4342c1af786f76697aeab17d598b6 an item may be queued and processed later. While this is OK for mbufs, this is a problem for control messages. In the framework: - Add optional callback function pointer to an item. When item gets applied the callback is executed from ng_apply_item(). - Add new flag NG_PROGRESS. If this flag is supplied, then return EINPROGRESS instead of 0 in case if item failed to deliver synchronously and was queued. - Honor NG_PROGRESS in ng_snd_item(). In ng_socket: - When userland sends control message add callback to the item. - If ng_snd_item() returns EINPROGRESS, then sleep. This change fixes possible races in ngctl(8) scripts.
