2020-11-09vlib: fix trace number accountingBenoît Ganne1-6/+14
When using classifier to filter traces, not all packets will be traced. In that case, we should only count traced packets. Type: fix Change-Id: I87d1e217b580ebff8c6ade7860eb43950420ae78 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2020-11-04vlib: add postmortem pcap dispatch traceDave Barach1-4/+2
Inspired by a real-life conundrum: scenario X involves a vpp crash in ip4-load-balance because vnet_buffer(b)->ip.adj_index[VLIB_TX] is (still) set to ~0. The problem takes most of a day to occur, and we need to see the broken packet's graph trajectory, metadata, etc. to understand the problem. Fix a signed/unsigned ASSERT bug in vlib_get_trace_count(). Rename elog_post_mortem_dump() -> vlib_post_mortem_dump(), add dispatch trace post-mortem dump. Add FILTER_FLAG_POST_MORTEM so we can (putatively) capture a ludicrous number of buffer traces, without actually using more than one dispatch cycle's worth of memory.

2020-06-08vlib: stop inlining vlib_add_trace(...)Dave Barach1-2/+8
Packet tracing performance doesn't justify inlining vlib_add_trace(...) over 500 times. It makes a 15% text-segment size difference in a representative use-case: Inline: $ size .../vnet_skx.dir/ipsec/ipsec_input.c.o text data bss dec hex filename 6831 80 0 6911 1aff .../vnet_skx.dir/ipsec/ipsec_input.c.o Not inline: $ size .../vnet_skx.dir/ipsec/ipsec_input.c.o text data bss dec hex filename 5776 80 0 5856 16e0 .../vnet_skx.dir/ipsec/ipsec_input.c.o Retain the original code as vlib_add_trace_inline, instantiate once as vlib_add_trace.

2019-12-05classify: vpp packet tracer supportDave Barach1-0/+16
Configure n-tuple classifier filters which apply to the vpp packet tracer. Update the documentation to reflect the new feature. Add a test vector. Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: Iefa911716c670fc12e4825b937b62044433fec36

2019-07-26dhcp: send unicast and broadcast packets via the IP adjacencyNeale Ranns1-1/+1
Type: feature this means DHCP packets are subject to the IP features configured on the interface - the unicast packets already were sent throught the adj - added UT for DHCP client sending a unicast renewal Change-Id: Id50db0b71822f44bf7cb639a524195cdc9873526 Signed-off-by: Neale Ranns <nranns@cisco.com>

vlib_add_trace, and one to post-process the captured content immediately after trace filtering. Change-Id: Ieb521686d8c0e7ce1a0ef325f7abdde613e1eb9c Signed-off-by: Gary Boon <gboon@cisco.com>
2018-08-24Clean up packet tracer, especially "clear trace"Dave Barach1-0/+13
There are multiple trace enablement schemes. It's easy to end up in vlib_add_trace with tracing disabled insofar as the packet tracer is concerned. When that happens, return the address of a per-system dummy trace record. Change-Id: I929391b8be4ed57e26e291afdc509a15f09a3160 Signed-off-by: Dave Barach <dave@barachs.net>
