* lib: Automated cleanup of cdefs and other formattingWarner Losh2023-11-271-1/+0
| | | | | | | | | | | | | | | | Apply the following automated changes to try to eliminate no-longer-needed sys/cdefs.h includes as well as now-empty blank lines in a row.

* Atomically update the global gMsgId in libnetgraph.Mark Johnston2019-05-101-7/+4
| | | | | | | | | | | | | | | | | Otherwise concurrently running threads may inadvertently use the same token for different messages. Preserve the behaviour of disallowing negative message tokens, but allow a message token value of zero since this simplifies the code a bit and tokens are documented to be non-negative.

* In the splnet(9) times netgraph(4) was synchronous and if a messageGleb Smirnoff2006-01-121-0/+16
| | | | | | | | | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=154265

* - Added three new interfaces, NgAllocRecvMsg(), NgAllocRecvAsciiMsg(),Ruslan Ermilov2004-01-271-8/+45
| | | | | | | | | | | | | | 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().

* Add two new generic control messages, NGM_ASCII2BINARY andArchie Cobbs1999-11-301-2/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | NGM_BINARY2ASCII, which convert control messages to ASCII and back. This allows control messages to be sent and received in ASCII form using ngctl(8), which makes ngctl a lot more useful. This also allows all the type-specific debugging code in libnetgraph to go away -- instead, we just ask the node itself to do the ASCII translation for us. Currently, all generic control messages are supported, as well as messages associated with the following node types: async, cisco, ksocket, and ppp. See /usr/share/examples/netgraph/ngctl for an example of using this. Also give ngctl(8) the ability to print out incoming data and control messages at any time. Eventually nghook(8) may be subsumed. Several other misc. bug fixes.
