| * IB/ehca: Tweak trace message formatHoang-Nam Nguyen2006-10-02
| | | | | | | | | | | | | | Add an extra space to make things more readable. Signed-off-by: Hoang-Nam Nguyen <hnguyen@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
| * IB/ehca: Fix device registrationHoang-Nam Nguyen2006-10-02
| | | | | | | | | | | | | | | | | | | | Move the call to ib_register_device() later, since a device should not be registered until it is completely read to be used. This fixes crashes that occur if an upper-layer driver such as IPoIB is loaded before the ehca module.

| * RDMA/cma: Fix device removal raceKrishna Kumar2006-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The race is as follows: A process : cma_process_remove() calls cma_remove_id_dev(), which sets id state to CMA_DEVICE_REMOVAL and calls wait_event(dev_remove). B process : cma_req_handler() had incremented dev_remove, and calls cma_acquire_ib_dev() and on failure calls cma_release_remove(), which does a wake_up of cma_process_remove(). Then cma_req_handler() calls rdma_destroy_id(); A Process : cma_remove_id_dev() gets woken and checks the state of id, and since it is still (wrongly) CMA_DEVICE_REMOVAL, it calls notify_user(id) and if that fails, the caller - cma_process_remove() calls rdma_destroy_id(id). Two processes can call rdma_destroy_id(), resulting in one de-referencing kfreed id_priv. Fix is for process B to set CMA_DESTROYING in cma_req_handler() so that process A will return instead of doing a rdma_destroy_id().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | If the driver is not configured for `no way out`, then the open method should not automatically allow the setting of allow_close to CLOSE_STATE_ALLOW. The setting of allow_close nullifies the use of the magic close via the write path. It means that in the default state, the watchdog will shut-down even if the magic close has not been issued.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were plagued by our interrupt handler posting a watchdog event which could occur when our adapter was going down in case a late packet arrived just before e1000_down() finished. This caused the watchdog timer to start after the NIC was down and keep rescheduling it every N seconds. Once the driver unloaded it would panic. Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com>
