* [SCSI] fnic: Allow multicast and unicast address registrations for fnicVenkata Siva Vijayendra Bhamidipati2010-02-172-1/+3
| | | | | | | | | | | | | To enable FIP support in fnic, we have to register with hardware to receive FIP solication frames on a well-known multicast address. Before FIP support, the firmware interface allowed multicast address registrations only for enic devices. This is a minor change in fnic to allow the firmware interface to now register mcast addresses for fnic too.

* [SCSI] fcoe: Only rmmod fcoe.ko if there are no active connectionsRobert Love2010-02-171-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we're gracefully tearing down each active connection when fcoe.ko is removed. We shouldn't allow the user to destroy connections by removing the module. We should force the user to destroy each connection and then the module can be removed. This patch makes it so a refrerence count on the module is taken each time a fcoe_interface is created. The reference count is dropped when the fcoe_interface is destroyed. This makes it so that module_exit() doesn't get called unless all fcoe_interfaces have been destroyed. This patch leaves the removal of interfaces in the module_exit routine so that if the user does a 'rmmod -f' we'll clean everything up before removing the module. The module_put line was put before the out_putdev goto line because we should only be decrementing the reference count if a fcoe_interface is actually destroyed. If we can't find the netdev or the fcoe_interface then it's assumed that something else has destroyed the fcoe_interface and it would have decremented the reference count at that time.

* [SCSI] libfc: call ddp setup for only FCP reads to avoid accessing junk fsp ↵Vasu Dev2010-02-172-4/+1
| | | | | | | | | | | | | | | | | | | | pointer Adds check to call fc_fcp_ddp_setup for only FCP read cmds to avoid accessing junk fsp pointer at least in ESX since non FCP frame had junk fsp value, though fsp is implicitly initialized to null by __alloc_skb but with this patch no more relying on fsp initialized to null value and hitting junk fsp ptr access. Removes fsp pointer checking in fc_fcp_ddp_setup as this is not needed any more since its only caller for FCP read will always have a valid fsp.

* [SCSI] libiscsi: reset cmd timer if cmds are making progressMike Christie2010-02-171-4/+49
| | | | | | | | | | | | | | | | | | | | | | This patch resets the cmd timer if cmds started before the timedout command are making progress. The idea is that the cmd probably timed out because we are trying to exeucte too many commands. If it turns out that the device the IO timedout on was bad or the cmd just got screwed up but other IO/devs were ok then we will will figure this out when the cmds ahead of the timed out one complete ok. This also fixes a bug where we were sort of detecting this by setting the last_timeout and last_xfer to the same value when the task was allocated. That caught the case where we never got to send any IO for it. However, if the problem had started right before we started the new task, then we were forced to wait an extra cmd timeout seconds to start the scsi eh.

* [SCSI] hpsa: fix bug in adjust_hpsa_scsi_tableStephen M. Cameron2010-02-171-6/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fix bug in adjust_hpsa_scsi_table which caused devices which have changed size, etc. to do the wrong thing. The problem was as follows: The driver maintains its current idea of what devices are present in the h->dev[] array. When it updates this array, it scans the hardware, and produces a new list of devices, call it sd[], for scsi devices. Then, it compares each item in h->dev[] vs. sd[], and any items which are not present sd it removes from h->dev[], and any items present in sd[], but different, it modifies in h->dev[]. Then, it looks for items in sd[] which are not present in h->dev[], and adds those items into h->dev[]. All the while, it keeps track of what items were added and removed to/from h->dev[]. Finally, it updates the SCSI mid-layer by removing and adding the same devices it removed and added to/from h->dev[]. (modified devices count as a remove then add.) originally, when a "changed" device was discovered, it was removed then added to h->dev[]. The item was added to the *end* of h->dev[]. And, the item was removed from sd[] as well (nulled out). As it processed h->dev[], these newly added items at the end of the list were encountered, and sd[] was searched, but those items were nulled out. So they ended up getting removed immediately after they were added. The solution is to have a way to replace items in the h->dev[] array instead of doing a remove + add. Then the "changed" items. are not encountered a second time, and removed. Signed-off-by: Stephen M. Cameron <scameron@beardog.cce.hp.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
