| | | | | | | | | | | | | | | | | | | | | | | | | | | virtualization work done by Marko Zec (zec@). This is the first in a series of commits over the course of the next few weeks. Mark all uses of global variables to be virtualized with a V_ prefix. Use macros to map them back to their global names for now, so this is a NOP change only. We hope to have caught at least 85-90% of what is needed so we do not invalidate a lot of outstanding patches again. Obtained from: //depot/projects/vimage-commit2/...

| | | | | | | | | | | | | | | | to embed up to four counters in outgoing packets. The message specifies the offset at which the counter should be inserted as well as the parameters of the counter. Example usage: ngctl msg src0: setcounter \ '{ index=0 offset=0x40 flags=1 width=4 increment=1 max_val=12345 }' Sponsored by: Sandvine Incorporated Notes: svn path=/head/; revision=167160
* Add "settimestamp" and "gettimestamp" messages, providing the the abilityEd Maste2007-03-011-5/+122
| | | | | | | | | | | | | | | | to embed a timestamp (struct timeval) in outgoing packets. The message specifies the offset at which the timestamp should be inserted. NG_SOURCE(4) gives an example usage that queues an ICMP packet. Using that example, the following command will insert a timestamp in the ICMP's data payload: ngctl msg src0: settimestamp '{ offset=0x2a flags=1 }' Sponsored by: Sandvine Incorporated Notes: svn path=/head/; revision=167156

* Major overhaul and cleanup of ng_source node.Gleb Smirnoff2005-04-051-162/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Functional changes: - Cut struct source_hookinfo. Just use hook_p pointer. - Remove "start_now" command. "start" command now requires number of packets to send as argument. "start" command actually starts sending. Move the code that actually starts sending from ng_source_rcvmsg() to ng_source_start(). - Remove check for NG_SOURCE_ACTIVE in ng_source_stop(). We can be called with flag cleared (see begin of ng_source_intr()). - If NG_SEND_DATA_ONLY() use log(LOG_DEBUG) instead of printf(). Otherwise we will *flood* console. - Add ng_connect_t method, which sends NGM_ETHER_GET_IFNAME command to "output" hook. Cut ng_source_request_output_ifp(). Refactor ng_source_store_output_ifp() to use ifunit() and don't muck through interface list. - Add "setiface" command, which gives ability to configure interface in case when ng_source_connect() failed. This happens, when we are not connected directly to ng_ether(4) node. - Remove KASSERTs, which can never fire. - Don't check for M_PKTHDR in rcvdata method. netgraph(4) does this for us. Style: - Assign sc_p = NG_NODE_PRIVATE(node) in declaration, to be consistent with style of other nodes. - Sort variables. - u_intXX -> uintXX. - Dots at ends of comments.
