USB: mark uas driver as BROKEN

2012-12-17T17:27:14Z

commit fb37ef98015f864d22be223a0e0d93547cd1d4ef upstream. As reported https://bugzilla.kernel.org/show_bug.cgi?id=51031, the UAS driver causes problems and has been asked to be not built into any of the major distributions. To prevent users from running into problems with it, and for distros that were not notified, just mark the whole thing as broken. Acked-by: Sarah Sharp Signed-off-by: Greg Kroah-Hartman

uas: task mgmt & error handling

2012-06-25T18:51:01Z

Add task management support, wind up in abort and device reset error handlers. Cancel all in-flight urbs in bus reset handler. Signed-off-by: Gerd Hoffmann Signed-off-by: Greg Kroah-Hartman

uas: track urbs, kill inflight urbs on disconnect.

2012-06-25T18:51:00Z

Use separate anchors for data and sense urbs, which I think will be useful when implementing error handling. Signed-off-by: Gerd Hoffmann Signed-off-by: Greg Kroah-Hartman

uas: improve error handling

2012-06-25T18:51:00Z

(1) Handle data pipe errors: When the data urb failed we didn't transfer anything, update scsi_cmnd accordingly. (2) Cancel data transfers when we got back an error on the status pipe. Signed-off-by: Gerd Hoffmann Signed-off-by: Greg Kroah-Hartman

uas: keep track of command state, finish scsi cmd when really done.

2012-06-25T18:50:59Z

Set state bits after submitting data urbs & command urbs, so we know what is in flight. Clear data bits when the data urb is finished, clear command bit when we see the status urb for the command. Finish the scsi command after running both status and data completion handlers for the command. Add a cmd status logging function for debugging purposes. Hook it into the error handler, so we see in the log what status a command is in which the scsi layer wants cancel. Signed-off-by: Gerd Hoffmann Signed-off-by: Greg Kroah-Hartman

uas: fix sense urb handling

2012-06-25T18:50:59Z

Stop reusing sense urbs, just allocate a fresh one each time and free it when done. Stop storing a sense urb pointer in the scsi request, all you can do with it is misusing. For example requeuing the sense urb, then f*ck it up by picking the wrong one in case tagged requests don't finish in the same order you've submitted them. Also note that (not-yet supported) task management ops don't have a scsi request in the first place. Signed-off-by: Gerd Hoffmann Signed-off-by: Greg Kroah-Hartman
