The integration of this feature in OVS has been postponed following feedback how the current API forced the complexity on the application side. There is no contributor working on making those changes.
The feature has no other identified opensource consumer. On the other hand, this feature has been left unattended for some years now while the "normal" datapath is actively maintained. It is highly likely the async datapath code, which never underwent a stabilisation phase, is riddled with bugs. Given the craziness around finding security bugs with AI, and since the vhost library is a good target, I propose to drop this feature and reduce the library attack surface. -- David Marchand David Marchand (3): examples: stop using vhost async datapath vhost: refuse async datapath vhost: drop async datapath doc/guides/prog_guide/vhost_lib.rst | 151 +- doc/guides/rel_notes/release_26_11.rst | 20 + examples/vhost/Makefile | 2 - examples/vhost/main.c | 436 +--- examples/vhost/main.h | 21 +- examples/vhost/meson.build | 2 - examples/vhost_crypto/Makefile | 1 - examples/vhost_crypto/main.c | 3 +- examples/vhost_crypto/meson.build | 1 - lib/vhost/meson.build | 3 +- lib/vhost/rte_vhost.h | 2 +- lib/vhost/rte_vhost_async.h | 293 --- lib/vhost/socket.c | 27 +- lib/vhost/vhost.c | 434 ---- lib/vhost/vhost.h | 115 - lib/vhost/vhost_user.c | 215 +- lib/vhost/virtio_net.c | 3275 +++++------------------- 17 files changed, 708 insertions(+), 4293 deletions(-) delete mode 100644 lib/vhost/rte_vhost_async.h -- 2.54.0
