Added changes in ovn-nbctl, ovn-sbctl, northd and in ovn-controller. While Mirror creation just creates the mirror, the lsp-attach-mirror triggers the sequence to create Mirror in OVS DB on compute node. OVS already supports Port Mirroring.
Note: This is targetted to mirror to destinations anywhere outside the cluster where the analyser resides and it need not be an OVN node. Example commands are as below: Mirror creation ovn-nbctl mirror-add mirror1 gre 0 from-lport 10.10.10.2 Attach a logical port to the mirror. ovn-nbctl lsp-attach-mirror sw0-port1 mirror1 Detach a source from Mirror ovn-nbctl lsp-detach-mirror sw0-port1 mirror1 Mirror deletion ovn-nbctl mirror-del mirror1 Co-authored-by: Veda Barrenkala <[email protected]> Signed-off-by: Veda Barrenkala <[email protected]> Signed-off-by: Abhiram R N <[email protected]> --- V1 --> V2 : Addressed Review comments i) Created new ENGINE node in OVN controller ii) Added files mirror.c and mirror.h where the handling is taken care. iii) Added a test in ovn.at NOTE: 1 test is failing i.e ovn-performance.at. Its something to do with the handler as it passes when I comment out the noop_handler. Need some guidance there on what could be causing this issue. and how to fix it. ./ovn-performance.at:363: test $rc -eq 0 -a $rv -eq 1 controller/automake.mk | 4 +- controller/mirror.c | 392 ++++++++++++++++++++++++++++++++++++ controller/mirror.h | 50 +++++ controller/ovn-controller.c | 187 ++++++++++++++++- northd/en-northd.c | 4 + northd/inc-proc-northd.c | 4 + northd/northd.c | 118 +++++++++++ northd/northd.h | 2 + ovn-nb.ovsschema | 31 ++- ovn-nb.xml | 57 ++++++ ovn-sb.ovsschema | 23 ++- ovn-sb.xml | 46 +++++ tests/ovn-nbctl.at | 80 ++++++++ tests/ovn.at | 155 ++++++++++++++ utilities/ovn-nbctl.c | 345 +++++++++++++++++++++++++++++++ utilities/ovn-sbctl.c | 4 + 16 files changed, 1496 insertions(+), 6 deletions(-) create mode 100644 controller/mirror.c create mode 100644 controller/mirror.h diff --git a/controller/automake.mk b/controller/automake.mk index c2ab1bbe6..334672b4d 100644 --- a/controller/automake.mk +++ b/controller/automake.mk @@ -41,7 +41,9 @@ controller_ovn_controller_SOURCES = \ controller/ovsport.h \ controller/ovsport.c \ controller/vif-plug.h \ - controller/vif-plug.c + controller/vif-plug.c \ + controller/mirror.h \ + controller/mirror.c controller_ovn_controller_LDADD = lib/libovn.la $(OVS_LIBDIR)/libopenvswitch.la man_MANS += controller/ovn-controller.8 diff --git a/controller/mirror.c b/controller/mirror.c new file mode 100644 index 000000000..fe4f20184 --- /dev/null +++ b/controller/mirror.c @@ -0,0 +1,392 @@ +/* Copyright (c) 2022 Red Hat, Inc. + * + * Licensed under the Apache License, Version 2.0 (the "License");
