MAC binding aging is currently broken in terms that the entries are never refreshed and always expire even with the active traffic. And there is another situation where ovn-controller skips an update and then misses the threshold. This also affects FDB entries.
These issues result in high latency spikes and packet drops on CoPP. Tests are also half-broken and unable to catch these issues. Fixing the code and the tests. Ilya Maximets (5): tests: Fix incorrect invocations of send_garp. tests: Fix use of bash arrays in MAC binding tests. mac-cache: Fix MAC binding entry lookup for timestamp refresh. mac-cache: Fix expiration of active MAC binding due to skipped update. mac-cache: Fix expiration of active FDB entry due to skipped update. controller/mac-cache.c | 191 +++++++++++++++++++++++------- controller/mac-cache.h | 10 +- controller/ovn-controller.c | 2 +- controller/pinctrl.c | 9 +- tests/ovn-macros.at | 3 +- tests/ovn.at | 227 +++++++++++++++++++++++++++++++----- 6 files changed, 363 insertions(+), 79 deletions(-) -- 2.47.0 _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
