Add "setcounter" and "getcounter" messages, providing the the ability2007-03-02T01:44:04ZEd Masteemaste@FreeBSD.org2007-03-02T01:44:04Zurn:sha1:577421ebc5d23cfe109278eb493aa668195d1e70
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 }'

Add "settimestamp" and "gettimestamp" messages, providing the the ability2007-03-01T23:16:17ZEd Masteemaste@FreeBSD.org2007-03-01T23:16:17Zurn:sha1:5f87dd698c09408e51e4cc31946117003debf270
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 }'

Implement an upper limit for packets per second sent by node.2005-12-23T19:14:38ZGleb Smirnoffglebius@FreeBSD.org2005-12-23T19:14:38Zurn:sha1:72235857719ffee76b1a620edf1c2a68570af007Major overhaul and cleanup of ng_source node.2005-04-05T17:22:05ZGleb Smirnoffglebius@FreeBSD.org2005-04-05T17:22:05Zurn:sha1:d8f5d037f88964232fecf59e885843bbe22aa77c
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.

Make some basic grammar and style fixes to ng_source.c and ng_source.h.2005-03-10T21:50:50ZBosko Milekicbmilekic@FreeBSD.org2005-03-10T21:50:50Zurn:sha1:2b0ffc021625d5703be58d172f5cbf461d53de11
The latter was particularly violated by someone's editor in the past, due
to an effect I like to call "premature linewrapping."

This is done to keep both versions in RELENG_5 and support both APIs.
