[SCSI] fcoe: fix fcoe in a DCB environment by adding DCB notifiers to set skb priority

2011-12-15T07:02:07+00:00

Use DCB notifiers to set the skb priority to allow packets
to be steered and tagged correctly over DCB enabled drivers
that setup traffic classes.

This allows queue_mapping() routines to be removed in these
drivers that were previously inspecting the ethertype of
every skb to mark FCoE/FIP frames.

[SCSI] bnx2i: Fixed kernel panic caused by unprotected task->sc->request deref

2011-12-14T13:05:23+00:00

During session recovery, the conn_stop call will trigger a flush
to all outstanding SCSI cmds in the xmit queue.  This will set
all outstanding task->sc to NULL prior to the session_teardown
call which frees the task memory.

In the bnx2i SCSI response processing path, only the task was being checked
for NULL under the session lock before the task->sc->request dereferencing.
If there are outstanding SCSI cmd responses pending for process, the
following kernel panic can be exposed where task->sc was found to be NULL.

 Call Trace:

This patch adds the !task->sc check and also protects the sc dereferencing
under the session lock.

[SCSI] qla4xxx: a small loop fix

2011-12-14T11:40:43+00:00

When the qla4xxx_get_fwddb_entry returns QLA_ERROR
the nex_idx is not updated,
      for (idx = 0; idx < max_ddbs; idx = next_idx) {
                ret = qla4xxx_get_fwddb_entry(ha, idx, NULL, 0, NULL,
                                              &next_idx, &state, &conn_err,
                                                NULL, NULL);
                if (ret == QLA_ERROR)
                        continue;

This means there is a risk that the 'idx < max_ddbs' condition will never
met and the loop will loop forever.
Fix this by explicitly increasing the next_idx in the error condition.

Maybe a break instead of continue is more appropriate, leaving the decision
on the qlogic maintainer.

[SCSI] qla4xxx: fix flash/ddb support

2011-12-14T11:40:43+00:00

With open-iscsi support, target entries persisted in the FLASH were not
login. Added support in the qla4xxx driver to do the login on probe
time to the target entries saved in the FLASH by user.
With this changes upgrade to the new kernel with open-iscsi support in
qla4xxx will ensure users original target entries login on driver load
