From f2bf8d3d4c6514c104308b3c9021a4bc4afe3abc Mon Sep 17 00:00:00 2001 From: Yousong Zhou Date: Wed, 5 Sep 2018 06:21:51 +0000 Subject: [PATCH] openvswitch: provide in-tree kmod builds Open vSwitch 2.10 introduces meters support to the kernel datapath. In upstream Linux, the feature is only available since 4.15 This is mainly for make the newly introduced meter features in linux kernel datapath more easily available root@OpenWrt:/# ovs-ofctl -OOpenFlow13 meter-features br0 OFPST_METER_FEATURES reply (OF1.3) (xid=0x2): max_meter:4294967295 max_bands:1 max_color:0 band_types: drop capabilities: kbps pktps burst stats root@OpenWrt:/# Size comparison between in-tree and upstreamed modules are attached 2800 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch-geneve-intree/lib/modules/4.14.67/vport-geneve.ko 2736 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch-geneve/lib/modules/4.14.67/vport-geneve.ko 2596 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch-gre-intree/lib/modules/4.14.67/vport-gre.ko 2536 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch-gre/lib/modules/4.14.67/vport-gre.ko 288320 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch-intree/lib/modules/4.14.67/openvswitch.ko 118984 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch/lib/modules/4.14.67/openvswitch.ko 2792 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch-lisp-intree/lib/modules/4.14.67/vport-lisp.ko 2788 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch-stt-intree/lib/modules/4.14.67/vport-stt.ko 3668 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch-vxlan-intree/lib/modules/4.14.67/vport-vxlan.ko 3400 Sep 5 08:47 ipkg-mips_24kc/kmod-openvswitch-vxlan/lib/modules/4.14.67/vport-vxlan.ko Signed-off-by: Yousong Zhou --- net/openvswitch/Makefile | 180 ++++++++++++------ net/openvswitch/README.md | 33 ++++ ...linux-Use-unsigned-int-for-ifi_flags.patch | 2 +- ...-interface-flag-survive-internal-por.patch | 2 +- ...host-target-python-for-cross-compile.patch | 2 +- .../0103-ovs-ctl-fix-setting-hostname.patch | 2 +- .../0104-ovs-lib-fix-install_dir.patch | 2 +- .../0105-build-disable-building-tests.patch | 2 +- ...e-compatible-with-busybox-ip-command.patch | 2 +- ...CH-when-building-linux-datapath-modu.patch | 28 +++ 10 files changed, 188 insertions(+), 67 deletions(-) create mode 100644 net/openvswitch/patches/0107-datapath-use-KARCH-when-building-linux-datapath-modu.patch diff --git a/net/openvswitch/Makefile b/net/openvswitch/Makefile index 373ca8c26..9ed24eec2 100644 --- a/net/openvswitch/Makefile +++ b/net/openvswitch/Makefile @@ -9,9 +9,14 @@ include $(TOPDIR)/rules.mk include $(INCLUDE_DIR)/kernel.mk +# Checklist on version bump +# +# -
