Fix for quite a special case when userland emulates a netgraph node, and

2013-03-11T13:05:11Z

userland can reply to a message with NGM_HASREPLY bit set. In this case we should not wait for a response to a responce. PR: 176771 Submitted by: Keith Reynolds

In the splnet(9) times netgraph(4) was synchronous and if a message

2006-01-12T19:14:40Z

had been replied, the reply was always delivered to the originator synchronously. With introduction of netgraph item callbacks and a wait channel with mutex in ng_socket(4), we have fixed the problem with ngctl(8) returning earlier than the command has been proceeded by target node. But still ngctl(8) can return prior to the reply has arrived to its node. To fix this: - Introduce a new flag for netgraph(4) messages - NGM_HASREPLY. This flag is or'ed with message like NGM_READONLY. - In netgraph userland library if we have sent a message with NGM_HASREPLY flag, then select(2) until reply comes. - Mark appropriate generic commands with NGM_HASREPLY flag, gathering them into one enum {}. Bump generic cookie.
