Subject: [PATCH 0/4] vsock: cancel connect packets when failing to connect
Date: Wed,  7 Dec 2016 18:00:17 +0800	[thread overview]
Message-ID: <1481104821-77294-1-git-send-email-bergwolf@gmail.com> (raw)

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.

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
