From 1705a6baefe205bb6792b547c7376eee3f328a71 Mon Sep 17 00:00:00 2001 From: Pim van Pelt Date: Thu, 9 Sep 2021 17:53:09 +0000 Subject: linux-cp: Add VPP->Linux synchronization Part 1 -- notes in https://ipng.ch/s/articles/2021/08/13/vpp-2.html Add the ability for VPP to copy out (sync) its state from the dataplane to Linux Interface Pairs, when they exist. Gated by a configuration flag (linux-cp { lcp-sync }), and by a CLI option to toggle on/off, synchronize the following events: - Interface state changes - Interface MTU changes - Interface IPv4/IPv6 address add/deletion In VPP, subints can have any link state and MTU, orthogonal to their phy. In Linux, setting admin-down on a phy forces its children to be down as well. Also, in Linux, MTU of children must not exceed that of the phy. Add a state synchronizer which walks over phy+subints to ensure Linux and VPP end up in the same consistent state. Part 2 -- notes in https://ipng.ch/s/articles/2021/08/15/vpp-3.html Add the ability for VPP to autocreate sub-interfaces of existing Linux Interface pairs. Gated by a configuration flag (linux-cp { lcp-auto-subint }), and by a CLI option to toggle on/off, synchronize the following event: - Sub-interface creation (dot1q, dot1ad, QinQ and QinAD) A few other changes: - Add two functions into netlink.[ch] to delete ip4 and ip6 addresses. - Remove a spurious logline (printing MTU) in netlink.c. - Resolve a TODO around vnet_sw_interface_supports_addressing() Type: improvement Signed-off-by: Pim van Pelt Change-Id: I34fc070e80af4013be58d7a8cbf64296cc760e4e Signed-off-by: Pim van Pelt --- src/plugins/linux-cp/CMakeLists.txt | 1 + 1 file changed, 1 insertion(+) (limited to 'src/plugins/linux-cp/CMakeLists.txt') diff --git a/src/plugins/linux-cp/CMakeLists.txt b/src/plugins/linux-cp/CMakeLists.txt index 080f73ecce4..5053207fff4 100644 --- a/src/plugins/linux-cp/CMakeLists.txt +++ b/src/plugins/linux-cp/CMakeLists.txt @@ -27,6 +27,7 @@ include_directories(${LIBMNL_INCLUDE_DIR}) add_vpp_library(lcp SOURCES lcp_interface.c + lcp_interface_sync.c lcp_adj.c lcp.c -- cgit 1.2.3-korg
