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.

Make this compile with GCC4 by fixing a few signedness related warnings.

- Added three new interfaces, NgAllocRecvMsg(), NgAllocRecvAsciiMsg(),

and NgAllocRecvData(), that dynamically allocate buffer for a binary message, an ascii message, and a data packet, respectively. The size of the allocated buffer is equal to the socket's receive buffer size to guarantee that a message or a data packet is not truncated. - Get rid of the static size buffer in NgSendAsciiMsg().

Replace occurences of the magic constant 2 with an offsetof macro call that computes the size of the leading members of the sockaddr. Use strlcpy instead of sprintf where appropriate. Document the new changes in the man page.
