Under heavy load with large cluster testing, it may take longer to receive a response to MPA requests. Change the driver to wait longer after each rexmit to max time value. Signed-off-by: NFaisal Latif <faisal.latif@intel.com> Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Fix issues found by static code analysis: (1) Check if cm_node was successfully created for loopback connection. (2) schedule_nes_timer() does not free up allocated memory after encountering an error. There is a WARN_ON() for this condition. (3) there is a cm_node->freed flag which is set but not used.

While doing testing, there are failures as MPA Reject call is not handled. To handle MPA Reject call, following changes are done: *Handle inbound/outbound MPA Reject response message. When nes_reject() is called for pending MPA request reply, send the MPA Reject message to its peer (active side)cm_node. The peer cm_node (active side) will indicate Reject message event for the pending Connect Request. *Handle MPA Reject response message for loopback connections and listener. When MPA Request is rejected, check if it is a loopback connection and if it is then it will send Reject message event to its peer loopback node. Also when destroying listener, check if the cm_nodes for that listener are loopback or not. *Add gracefull connection close with the MPA Reject response message. Send gracefull close (FIN, FIN ACK..) to terminate the cm_nodes. *Some code re-org while making the above changes. Removed recv_list and recv_list_lock from the cm_node structure as there can be only one receive close entry on the timer. Also implemented handle_recv_entry() as receive close entry is processed from both nes_rem_ref_cm_node() as well as nes_cm_timer_tick().

There is no lock protecting tx_free_list thus causing a system crash when skb_dequeue() is called and the list is empty. Since it did not give any performance boost under heavy load, remove it to simplify the code. Replace get_free_pkt() with dev_alloc_skb() to allocate MAX_CM_BUFFER skb for connection establishment/teardown as well as MPA request/response.

Under heavy traffic, there is a small windows when an APBVT entry is not yet removed and a new connection is established. Packets for the new connection are dropped until APBVT entry is removed. This patch will forward the packets instead of dropping them.

In passive open, after indicating MPA request to rdma_cm, an incoming RST would fire a reset event to rdma_cm causing it to crash, since the current state is not connected. The solution is to wait for nes_accept() or nes_reject() before firing the reset event. If nes_accept() or nes_reject() is already done, then the reset event will be fired when RST is processed.

While processing connected_nodes list, we would release the lock when we need to send reset to remote partner. That created a window where the list can be modified. Change this into a two step process: place nodes that need processing on a local list then process the local list.

Major rework of CM connection setup/teardown. We had a number of issues with MPI applications not starting/terminating properly over time. With these changes we were able to run longer on larger clusters. * Remove memory allocation from nes_connect() and nes_cm_connect(). * Fix mini_cm_dec_refcnt_listen() when destroying listener. * Remove unnecessary code from schedule_nes_timer() and nes_cm_timer_tick(). * Functionalize mini_cm_recv_pkt() and process_packet(). * Clean up cm_node->ref_count usage. * Reuse skbs if available.

The session_id members of struct nes_cm_listener and struct nes_cm_node are write-only, so remove them. This allows the session_id member of struct nes_cm_core to be removed as well, since it is only used to write those other session_id values. This removes the use of current->tgid (which will be deprecated) pointed out by Pavel Emelyanov <xemul@openvz.org>.
