Here is the summary with links:
  - [net,v6,1/3] net: replace calls to sock->ops->connect() with kernel_connect()
    https://git.kernel.org/netdev/net/c/26297b4ce1ce
  - [net,v6,2/3] net: prevent rewrite of msg_name and msg_namelen in sock_sendmsg()
    (no matching commit)
  - [net,v6,3/3] net: prevent address rewrite in kernel_bind()
    https://git.kernel.org/netdev/net/c/c889a99a21bf

You are awesome, thank you!
