Subject: [RFC 0/3] vhost-net: netfilter support for RX path
Date: Sun, 8 Feb 2026 22:32:21 +0800 [thread overview]
Message-ID: <20260208143441.2177372-1-lulu@redhat.com> (raw)
This series adds a minimal vhost-net filter support for RX.
It introduces a UAPI for VHOST_NET_SET_FILTER and a simple
SOCK_SEQPACKET message header. The kernel side keeps a filter
socket reference and routes RX packets to userspace when
it was enabled.
Tested
- vhost=on and vhost=off
