Hi,
I am using ovs 2.1.2.
When I add flow with OFPFF_CHECK_OVERLAP flag, even having a flow with the
same priority and match in the ovs db, ovs doesn't response with an
ofp_error_msg with OFPET_FLOW_MOD_FAILED type and OFPFMFC_OVERLAP code.
the command as below:
ovs-ofctl add-flow br0 "check_overlap, priority=9, actions=output:20" -O
openflow13
The original code for checking OFPFF_CHECK_OVERLAP in the ofproto.c as
below:
.
.
rule = rule_from_cls_rule(classifier_find_rule_exactly(&table->cls, &cr));
.
.
.if (fm->flags & OFPUTIL_FF_CHECK_OVERLAP) {
......
I think the "if (fm->flags & OFPUTIL_FF_CHECK_OVERLAP) { " statement must
execute before
"rule = rule_from_cls_rule(classifier_find_rule_exactly(&table->cls,
&cr)); " statement.
And then the checking OFPFF_CHECK_OVERLAP mechanism works fine after I test.
