            Bug ID: 531
           Summary: ACL (librte_acl) Fails to match source ports
           Product: DPDK
           Version: 19.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: [email protected]
          Reporter: [email protected]

Target Milestone: ---

After upgrading to DPDK 19.11.3, one of our regression tests failed. A simplified version of the test that still fails is:
Creating a ruleset with two rules:
- drop udp packet with a range of source ports
- allow all udp traffic
Sending udp packet with source port outside the range
We expect the packet to be forwarded but it drops.

A workaround that work for us was replacing lib/librte_acl/acl_bld.c with the same file from DPDK 18.11.2.
