Currently, if a connect call fails on a signal or timeout (e.g., guest is still in the process of starting up), we'll just return to caller and leave the connect packet queued and they are sent even though the connection is considered a failure, which can confuse applications with unwanted false connect attempt.
The patchset enables vsock (both host and guest) to cancel queued packets when a connect attempt is considered to fail. v2 changelog: - fix queued_replies counting and resume tx/rx when necessary Peng Tao (4): vsock: track pkt owner vsock vhost-vsock: add pkt cancel capability vsock: add pkt cancel capability vsock: cancel packets when failing to connect drivers/vhost/vsock.c | 41 ++++++++++++++++++++++++++++++++ include/linux/virtio_vsock.h | 12 ++++++++++ net/vmw_vsock/af_vsock.c | 7 ++++++ net/vmw_vsock/virtio_transport.c | 42 +++++++++++++++++++++++++++++++++ net/vmw_vsock/virtio_transport_common.c | 14 +++++------ 5 files changed, 109 insertions(+), 7 deletions(-) -- 2.7.4 _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
