Added
- Introduce a new feature gate
NFTablesHostNetworkModeand an optionhostNetworkModeto supportnftablesfor proxyAll rules installed in the Node's host network by AntreaProxy. (#7545, @hongliangl) - Add support for Antrea Egress in hybrid mode. (#7239, @hongliangl)
- Add
directionflag toantctl packetcapturecommand. (#7195, @sratslla) - Add IPv6 support for PacketCapture feature, including ICMPv6 handling and new CLI filter options. (#7385, @harshgdev)
- Enhance PacketCapture to support matching arbitrary source or destination. (#7215, @harshgdev)
- Enhance PacketCapture to also capture packets at the destination Pod, in addition to the source. (#7289, @harshgdev)
- Add confederation identifier to the
antctl get bgppolicycommand response. (#7275, @Atish-iaf) - Add member ASNs to the
antctl get bgppolicycommand response. (#7425, @Atish-iaf) - Add
conntrack_poll_cycle_duration_secondsmetric to track the time taken to poll conntrack and update the connection store. (#7460, @antoninbas) - Add a
network-policy-delayflag toantctl check installationto configure the maximum policy realization delay. (#7427, @antoninbas) - Add resource requests for Windows container in Antrea deployment. (#7254, @XinShuYang)
- Accelerate Pod-to-Pod networking in
noEncapandhybridmodes by leveraging nftablesflowtableto reduce host network stack overhead. If some nftables dependencies are not met, it will fallback to the old behavior. The new behavior can also be disabled by explicitly settinghostNetworkAcceleration.enableto false. (#7324, @hongliangl)
