OVN is lenient with the types of logical switch ports. Maybe too lenient. This patch attempts to solve this problem on two fronts: 1) In ovn-nbctl, if you attempt to set the port type to an unknown type, the command will not end up setting the type. 2) In northd, when copying the port type from the northbound database to the corresponding port-binding in the southbound database, a warning will be issued if the port is of an unknown type. Signed-off-by: Mark Michelson <mmichels@redhat.com> --- v3: * OVN_NB_LSP_TYPES declaration is static * northd will not copy unknown port types to southbound DB * re-ordered port types in OVN_NB_LSP_TYPES v2: * Used ARRAY_SIZE to calculate length of OVN_NB_LSP_TYPES v1: * Initial patch --- ovn/lib/ovn-util.c | 30 +++++++++++++++++++ ovn/lib/ovn-util.h | 2 ++ ovn/northd/ovn-northd.c | 7 ++++- ovn/utilities/ovn-nbctl.c | 7 ++++- tests/ovn-nbctl.at | 73 +++++++++++++++++++++++++++++++++++++++++++++++ 5 files changed, 117 insertions(+), 2 deletions(-)
