First patch implements a new API for external backend to advertize its specific protocol features to vhost-user master. Second patch ensures a request not handled by the vhost-user library but by the external backend only will not be treated as an error or make the vhost lib to crash. Changes in v3: ============== - Fix and improve comments (Ilya) Changes in v2: ============== - Remove 'skip_master' param from documentation (Ilya) - Merge pre and post callback in a single one (Ilya) Changes in v1: ============== - Convert vhost-crypto to the API change (Ilya) - Fix build with recent GCC (fall-through) - Check request > VHOST_USER_NONE (Ilya) - Remove 'Requested invalid message type' check (Ilya) Changes in RFC v2: ================== - Fix build & git message - Add new enum for not handled messages & remove skip_master (Ilya) Maxime Coquelin (2): vhost: add API to set protocol features flags vhost: support requests only handled by external backend lib/librte_vhost/rte_vhost.h | 53 +++++++++-------- lib/librte_vhost/rte_vhost_version.map | 1 + lib/librte_vhost/socket.c | 14 +++++ lib/librte_vhost/vhost_crypto.c | 10 +++- lib/librte_vhost/vhost_user.c | 82 ++++++++++++++++---------- 5 files changed, 102 insertions(+), 58 deletions(-)
