| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a race while re-reading the device characteristics. After cleaning the memory area a cqr is build which reads the device characteristics. This may take a rather long time and the device characteristics structure is zero during this. Now it could be possible that the block tasklet starts working and a new cqr will be build. The build_cp command refers to the device characteristics structure and this may lead into a divide by zero exception. Fix this by re-reading the device characteristics into a temporary structur and copy the data to the original structure. Also take the ccwdev_lock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a ccw device appears not operational, inform the associated device driver and act according to the response: if the driver wants to keep the device, put it into the disconnected state. If not, or if there is no driver or if the device is not online, unregister it. This approach is consistent with no-path event handling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a memory leak in /proc/cio_ignore. The iterator is allocated in cio_ignore_proc_seq_start, but never freed in cio_ignore_proc_seq_stop, because we cannot use the iterator that was passed by seqfile. The seqfile interface passes the last seen iterator to the stop function and not the first one. Since our next function will return NULL at the end, the iter passed to cio_ignore_proc_seq_stop is NULL. The original iter has leaked. The solution is to use seq_open_private.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EHCI driver does some bounds checking when it's scheduling an iTD for an active endpoint. It sets the local variable start to stream->next_uframe and moves that variable further in the schedule if necessary. However, the driver fails to do anything with start before jumping to the ready label and setting the URB's starting frame to stream->next_uframe. Alan Stern confirms the EHCI driver should set stream->next_uframe to start before jumping.

Some USB mass-storage devices don't return any sense data when they encounter certain kinds of errors. The SCSI layer interprets this to mean that the operation should be retried, and the same thing happens -- over and over again with no limit. In some circumstances (such as when a bus reset occurs) that is the right thing to do, but not here. The patch checks for this condition (a transport failure with no sense data) and changes the result code to DID_ERROR and the sense code to Hardware Error. This does get only a limited number of retries, and so the command will fail relatively quickly instead of getting stuck in an infinite loop. This fixes a large part of Bugzilla #14118.

Note that both private data and tty are checked again before processing (possibly from work queue which also is cancelled on close).
