| * | init/Kconfig: move the trusted keyring config option to general setupPeter Foley2014-04-181-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SYSTEM_TRUSTED_KEYRING config option is not in any menu, causing it to show up in the toplevel of the kernel configuration. Fix this by moving it under the General Setup menu.

The SQ work request will never get processed, and should be completed with FLUSHED status. Function c4iw_flush_sq(), however was dropping the oldest SQ work request when in CLOSING or IDLE states, instead of completing the pending work request. If that oldest pending work request was actually complete and has a CQE in the CQ, then when that CQE is proceessed in poll_cq, we'll BUG_ON() due to the inconsistent SQ/CQ state. This is a very small timing hole and has only been hit once so far. The fix is two-fold: 1) c4iw_flush_sq() MUST always flush all non-completed WRs with FLUSHED status regardless of the QP state. 2) In c4iw_modify_rc_qp(), always set the "in error" bit on the queue before moving the state out of RTS. This ensures that the state transition will not happen while another thread is in post_rc_send(), because set_state() and post_rc_send() both aquire the qp spinlock. Also, once we transition the state out of RTS, subsequent calls to post_rc_send() will fail because the "in error" bit is set. I don't think this fully closes the race where the FW can get a FINI followed a SQ work request being posted (because they are posted to differente EQs), but the #1 fix will handle the issue by flushing the SQ work request.

| * | | | RDMA/cxgb4: Endpoint timeout fixesSteve Wise2014-04-111-33/+56

If there are continual CPL messages flowing into the driver, the endpoint timeout processing can be starved. This condition exposed the other bugs below. Solution: In process_work(), call process_timedout_eps() after each CPL is processed. 2) Connection events can be processed even though the endpoint is on the timeout list. If the endpoint is scheduled for timeout processing, then we must ignore MPA Start Requests and Replies. Solution: Change stop_ep_timer() to return 1 if the ep has already been queued for timeout processing. All the callers of stop_ep_timer() need to check this and act accordingly. There are just a few cases where the caller needs to do something different if stop_ep_timer() returns 1: 1) in process_mpa_reply(), ignore the reply and process_timeout() will abort the connection. 2) in process_mpa_request, ignore the request and process_timeout() will abort the connection. It is ok for callers of stop_ep_timer() to abort the connection since that will leave the state in ABORTING or DEAD, and process_timeout() now ignores timeouts when the ep is in these states. 3) Double insertion on the timeout list. Since the endpoint timers are used for connection setup and teardown, we need to guard against the possibility that an endpoint is already on the timeout list. This is a rare condition and only seen under heavy load and in the presense of the above 2 bugs. Solution: In ep_timeout(), don't queue the endpoint if it is already on the queue.

Adding the covers to hid_have_special_driver prevents loading the right hid drivers for the other two interfaces, all 3 get loaded with hid-microsoft.
