The\nresult is a significant reduction in installed binary size:\n\n pre-series: 279.37 MB\n post-series: 185.47 MB (~94 MB saved on Fedora 43 x86_64)\n\nAs part of the restructuring, the packets module is split into a net-proto\nmodule (network protocol handling) and dp-packet (datapath packet\noperations), with a handful of function renames to clarify the separation.\nThe public header openvswitch/packets.h is renamed to\nopenvswitch/net-proto.h accordingly.\n\nFuture work could split things further - vconn, ofpbuf, and netdev are\ncandidates - though the ofp* dependency graph makes that harder to\nuntangle.\n\nChanges since v2:\n - Fixed checkpatch warnings and errors (cast spacing, operator spacing,\n line length, for-loop whitespace, commit subject length).\n - Separated the public header rename into its own commit for clarity.\n - Moved dirs.h from libopenvswitch to libopenvswitchutils sources\n to be consistent with dirs.c.\n\nChanges since v1 (Aaron Conole <aconole@redhat.com>):\n - Reordered: flow_tnl_equal removal moved to patch 1 as suggested by\n David Marchand (independent cleanup, easier to review first)\n - Fixed: flow_tnl_src()/flow_tnl_dst() moved from lib/dp-packet.c to\n lib/flow.c as requested by David Marchand and Ilya Maximets\n - Fixed: missing packet_set_ipv6_flow_label and packet_set_ipv6_tc\n renames added to NEWS as pointed out by David Marchand\n - Fixed: FreeBSD build - added sys/socket.h before netinet/in.h in\n lib/net-proto.h, lib/dp-packet.c, and include/openvswitch/net-proto.h\n as acknowledged by Aaron Conole\n - Renamed: libovscommon -> libopenvswitchutils as suggested by David\n Marchand (who preferred libopenvswitchutils or -utils)\n - Renamed: include/openvswitch/packets.h ->\n include/openvswitch/net-proto.h as suggested by Ilya Maximets\n\nTimothy Redaelli (6):\n lib/packets: Remove flow_tnl_equal.\n lib/net-proto: Create module for generic network protocols.\n lib/ct-state: Move ct-state macros to their own header.\n lib: Rename include/openvswitch/packets.h to net-proto.h.\n lib/dp-packet: Fold the 'packets' module into dp-packets.\n libs: Introduce libopenvswitchutils for common routines.\n\n NEWS | 18 +-\n configure.ac | 2 +\n debian/rules | 4 +-\n include/openvswitch/automake.mk | 2 +-\n include/openvswitch/flow.h | 2 +-\n include/openvswitch/match.h | 2 +-\n include/openvswitch/meta-flow.h | 2 +-\n .../openvswitch/{packets.h => net-proto.h} | 7 +-\n lib/.gitignore | 1 +\n lib/automake.mk | 584 ++--\n lib/bfd.c | 2 +-\n lib/bfd.h | 2 +-\n lib/cfm.c | 2 +-\n lib/cfm.h | 1 -\n lib/classifier.c | 2 +-\n lib/conntrack-private.h | 1 -\n lib/conntrack.c | 12 +-\n lib/conntrack.h | 2 +-\n lib/ct-dpif.c | 1 +\n lib/ct-dpif.h | 3 +-\n lib/ct-state.h | 50 +\n lib/dhcp.h | 1 -\n lib/dp-packet.c | 1474 +++++++++++\n lib/dp-packet.h | 111 +-\n lib/dpctl.c | 1 -\n lib/dpif-netdev-extract-avx512.c | 1 -\n lib/dpif-netdev-lookup-generic.c | 2 +-\n lib/dpif-netdev-lookup.c | 1 +\n lib/dpif-netdev-private-extract.c | 1 +\n lib/dpif-netdev-private-flow.h | 1 +\n lib/dpif-netdev.c | 1 -\n lib/dpif-netdev.h | 1 -\n lib/dpif-netlink-rtnl.c | 1 +\n lib/dpif-netlink.c | 1 -\n lib/dpif-offload-dpdk-netdev.c | 3 +-\n lib/dpif-offload-dpdk.c | 3 +\n lib/dpif.c | 3 +-\n lib/dpif.h | 1 -\n lib/flow.c | 22 +-\n lib/flow.h | 159 +-\n lib/ipf.c | 2 +-\n lib/lacp.c | 1 -\n lib/lacp.h | 6 +-\n lib/libopenvswitchutils.pc.in | 11 +\n lib/libopenvswitchutils.sym.in | 4 +\n lib/lldp/lldp.c | 1 -\n lib/lldp/lldpd-structs.h | 1 -\n lib/lldp/lldpd.c | 1 -\n lib/lldp/lldpd.h | 1 -\n lib/mac-learning.c | 2 +\n lib/mac-learning.h | 1 -\n lib/match.c | 3 +-\n lib/mcast-snooping.h | 1 -\n lib/meta-flow.c | 5 +-\n lib/multipath.c | 1 -\n lib/net-proto.c | 893 +++++++\n lib/{packets.h => net-proto.h} | 411 +--\n lib/netdev-afxdp.c | 1 -\n lib/netdev-bsd.c | 1 -\n lib/netdev-dpdk.c | 1 -\n lib/netdev-dummy.c | 1 -\n lib/netdev-linux.c | 9 +-\n lib/netdev-native-tnl.c | 10 +-\n lib/netdev-native-tnl.h | 1 -\n lib/netdev-provider.h | 1 -\n lib/netdev-vport.c | 1 -\n lib/netdev-windows.c | 1 -\n lib/netdev.c | 1 -\n lib/netdev.h | 1 -\n lib/nx-match.c | 2 +-\n lib/odp-execute-avx512.c | 4 +-\n lib/odp-execute-private.c | 1 +\n lib/odp-execute.c | 1 -\n lib/odp-util.c | 8 +-\n lib/odp-util.h | 1 +\n lib/ofp-ct.c | 4 +-\n lib/ofp-ed-props.c | 2 -\n lib/ofp-match.c | 4 +-\n lib/ofp-parse.c | 2 +-\n lib/ofp-print.c | 1 -\n lib/ofp-util.c | 1 -\n lib/ovs-lldp.c | 1 -\n lib/ovs-lldp.h | 1 -\n lib/ovs-router.c | 1 -\n lib/packets.c | 2351 -----------------\n lib/pcap-file.c | 1 -\n lib/route-table-bsd.c | 2 +-\n lib/route-table.c | 1 -\n lib/rstp-common.h | 1 -\n lib/rstp-state-machines.c | 1 -\n lib/rstp.c | 1 -\n lib/rtnetlink.c | 2 +-\n lib/smap.c | 2 +-\n lib/socket-util.c | 2 +-\n lib/stp.c | 1 -\n lib/stream-ssl.c | 2 +-\n lib/stream-tcp.c | 1 -\n lib/stream-unix.c | 1 -\n lib/stream.c | 1 -\n lib/tc.c | 1 -\n lib/tnl-neigh-cache.c | 1 -\n lib/tnl-neigh-cache.h | 1 -\n lib/tnl-ports.h | 1 -\n lib/tun-metadata.c | 1 -\n lib/vconn.c | 1 -\n ofproto/bond.c | 1 -\n ofproto/bond.h | 1 -\n ofproto/in-band.c | 1 -\n ofproto/netflow.c | 1 -\n ofproto/ofproto-dpif-ipfix.c | 1 -\n ofproto/ofproto-dpif-monitor.h | 1 -\n ofproto/ofproto-dpif-sflow.c | 1 -\n ofproto/ofproto-dpif-upcall.c | 1 -\n ofproto/ofproto-dpif-xlate-cache.c | 1 -\n ofproto/ofproto-dpif-xlate.c | 3 +-\n ofproto/ofproto.c | 1 -\n ofproto/tunnel.c | 1 -\n ovsdb/automake.mk | 6 +-\n tests/automake.mk | 8 +-\n tests/test-classifier.c | 2 +-\n tests/test-conntrack.c | 3 +-\n tests/test-csum.c | 6 +-\n tests/test-lib-route-table.c | 3 +-\n tests/test-netflow.c | 4 +-\n tests/test-netlink-conntrack.c | 2 +\n tests/test-packets.c | 2 +-\n tests/test-rstp.c | 1 -\n tests/test-sflow.c | 2 +-\n tests/test-stp.c | 1 -\n utilities/automake.mk | 15 +-\n utilities/ovs-dpctl.c | 1 -\n utilities/ovs-ofctl.c | 2 +-\n vswitchd/automake.mk | 3 +-\n vswitchd/bridge.c | 1 -\n vtep/automake.mk | 2 +-\n 135 files changed, 3235 insertions(+), 3117 deletions(-)\n rename include/openvswitch/{packets.h => net-proto.h} (95%)\n create mode 100644 lib/ct-state.h\n create mode 100644 lib/libopenvswitchutils.pc.in\n create mode 100644 lib/libopenvswitchutils.sym.in\n create mode 100644 lib/net-proto.c\n rename lib/{packets.h => net-proto.h} (75%)\n delete mode 100644 lib/packets.c" }
