In the splnet times, netgraph was functional and synchronous. Nowadays,2005-07-05T17:35:20ZGleb Smirnoffglebius@FreeBSD.org2005-07-05T17:35:20Zurn: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.

Fix use of uninitialized variable len in ngd_send.2005-05-28T13:15:44ZBjoern A. Zeebbz@FreeBSD.org2005-05-28T13:15:44Zurn:sha1:7cceedd6b591b46851affd7fe741abe2e24b1d87
Note: len gets intialized to 0 for sap == NULL case only to
make compiler on amd64 happy. This has nothing todo with the
former uninitialized use of len in sap != NULL case.
