Originally* the patch was implemented to allow more parallel fmt_pkt calls in OVN test suite (that rely on a python AF_UNIX unixctl server to transform scapy string format strings into byte strings). The problem with parallel handling of more than 10 unixctl AF_UNIX requests to python servers was noticed here: https://github.com/ovn-org/ovn/commit/0baca3e519756cbe98a32526ccc637bb73468743 2. Now, Brian also reports listen backlog issues in OpenStack environments for INET sockets, see: https://mail.openvswitch.org/pipermail/ovs-discuss/2024-April/053049.html * the patch was part of a series of patches - https://patchwork.ozlabs.org/project/openvswitch/list/?series=382739&state=%2A&archive=both - that generally improve AF_UNIX unixctl socket handling, which I plan to revive later, but nothing stops us from merging this before I get to it. > Cheers, > > Eelco > > Acked-by: Eelco Chaudron <echau...@redhat.com> > > _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
