From 9137e5400699bed9f7c0095187839a8b38273100 Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Fri, 13 Sep 2019 17:47:50 -0400 Subject: misc: classifier-based packet trace filter See .../src/vnet/classify/trace_classify.h for the business end of the scheme. It would be best to hash pkts, prefetch buckets, and do the primary table lookups two at a time. The inline as given works, but perf tuning will be required. "At least it works..." Add "classify filter" debug cli, for example: classify filter mask l3 ip4 src dst \ match l3 ip4 dst 192.168.2.10 src 192.168.1.10 Add "pcap rx | tx trace ... filter" to use the current classify filter chain Patch includes sphinx documentation and doxygen tags. Next step: device-driver integration Type: feature Signed-off-by: Dave Barach Change-Id: I05b1358a769f61e6d32470e0c87058f640486b26 --- src/vnet/CMakeLists.txt | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/vnet/CMakeLists.txt') diff --git a/src/vnet/CMakeLists.txt b/src/vnet/CMakeLists.txt index 2a783810fdd..1e51f3d7102 100644 --- a/src/vnet/CMakeLists.txt +++ b/src/vnet/CMakeLists.txt @@ -384,6 +384,7 @@ list(APPEND VNET_API_FILES lldp/lldp.api) ############################################################################## list(APPEND VNET_SOURCES classify/vnet_classify.c + classify/trace_classify.h classify/ip_classify.c classify/in_out_acl.c classify/policer_classify.c @@ -400,6 +401,7 @@ list(APPEND VNET_MULTIARCH_SOURCES list(APPEND VNET_HEADERS classify/vnet_classify.h + classify/trace_classify.h classify/in_out_acl.h classify/policer_classify.h classify/flow_classify.h -- cgit 1.2.3-korg
