I have found the following issue after the series is applied to the latest kernel:
Test # 8 TIPC TIPC_IMPORTANCE test...STARTED! TEST FAILED unexpected number of send() errors errno = 113: No route to host Test # 1 Below is the procedure of how to reproduce above error: Prepare for two nodes. One is to run "tipcTS"; and on another node, we use the below commands to repeatedly run tipcTC test case: while [ true ]; do tipcTC 0; done About after 2 or 3 hours, the error above will appear.

The series does not add any functional change. 1. tipc socket state is derived from multiple variables like sock->state, tsk->probing_state and tsk->connected. This style forces us to export multiple attributes to the user space, which has to be backward compatible. 2. Abuse of sock->state cannot be exported to user-space without requiring tipc specific hacks in the user-space. - For connection less (CL) sockets sock->state is overloaded to tipc state SS_READY. - For connection oriented (CO) listening socket sock->state is overloaded to tipc state SS_LISTEN. This series is split into three: 1. A bug fix in patch-1 2. Express all tipc states using a single variable. This is done in patch#2-5. 3. Migrate the new tipc states to sk->sk_state. This is done in patch#6-12.
