2022-01-18virtio: remove admin-up flag during interface creationMohsin Kazmi2-4/+0
Type: fix During the interface creation time, (by default) admin-up flag is locally set for tap and virtio interfaces. While, in VPP the state of these interfaces are still admin-down. User needs to explicitly call 'set interface state <interface-name> up' to admin-up the newly created tap or virtio interface(s) in VPP. So, this behavior is inconsistent. This patch fixes the issue to have consistent behavior for given interface between local and global administration state.

2022-01-11linux-cp: Add VPP->Linux synchronizationPim van Pelt2-1/+46
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 <pim@ipng.nl> Change-Id: I34fc070e80af4013be58d7a8cbf64296cc760e4e Signed-off-by: Pim van Pelt <pim@ipng.nl>

Type: fix This fixes the GSO size calculation in af_packet which didn't include the ethernet size.
