2011-02-28[SCSI] fcoe, libfc: initialize EM anchors list and then update npiv EMsVasu Dev4-32/+29
EM anchors list initialization for only master port was not enough to keep npiv working as described here:- https://lists.open-fcoe.org/pipermail/devel/2011-January/011063.html So this patch moves fc_exch_mgr_list_clone to update npiv ports EMs once EM anchors list initialized. Also some cleanup, no need to set lport = NULL as that always get initialized later.

2011-02-28[SCSI] Revert "[SCSI] libfc: fix exchange being deleted when the abort ↵Parikh, Neerav1-5/+2
itself is timed out" When abort for an exchange timed out it didn't release the reference to the exchange resulting in a memory leak. After discussion with the author of the patch (CC) that introduced this bug it was suggested to revert that patch. This reverts commit ea3e2e72eeb3e8a9440a5da965914f9b12088626.

2011-02-28[SCSI] libfc: Fixing a memory leak when destroying an interfaceParikh, Neerav1-0/+1
When an fcoe interface is being destroyed; in the process the fcoe driver will try to release all the resources it had allocated for that interface including rports. But, it seems that it does not release the reference held for the name server rport in that process resulting into a memory leak. This patch fixes that memory leak.

2011-02-28[SCSI] lpfc: block target when port queueing limit is hitMike Christie1-1/+4
Instead of blocking the entire host when the port's queueing limit is hit, we should only block the port's target. This will allow IO to other ports to execute.

2011-02-28[SCSI] lpfc: force retry in queuecommand when port is transitioningMike Christie1-1/+1
If the port takes a while to transition we could exhaust the retries when using DID_TRANSPORT_DISRUPTED. For this case we do not want to use any of the cmd's retries, because if the command was running then when it got failed the retry counter was already incremented. And if this is the first time we are seeing the command, (it got queued because it slipped through during the race) then it should not have its retries incremented. The fc class will decide the correct handling later. Signed-off-by: Mike Christie <[email protected]> Acked-by: James Smart <[email protected]> Signed-off-by: James Bottomley <[email protected]>

2011-02-25[SCSI] qla2xxx: Check return value of fc_block_scsi_eh()Andrew Vasquez1-9/+20
The fc_block_scsi_eh() might return with status FAST_IO_FAIL indicating I/O has been terminated due to fast_io_fail timeout. In this case the rport is still blocked, so any error recovery will be failing on this port. Hence we need to check if the return value from fc_block_scsi_eh() is something other than 0, in which case it should just return with that status.

2011-02-25[SCSI] zfcp: Introduce new kmem_cache for FC request and response dataChristof Schmitt5-42/+47
A data buffer that is passed to the hardware must not cross a page boundary. zfcp uses a series of kmem_caches to align the data to not cross a page boundary. Introduce a new kmem_cache for the FC requests sent from the zfcp driver and use it for the ELS ADISC data. The goal is to migrate to the FC kmem_cache in later patches and remove the request specific kmem_caches.

2011-02-25[SCSI] zfcp: Replace kmem_cache for "status read" dataChristof Schmitt4-22/+15
zfcp requires a mempool for the status read data blocks to resubmit the "status read" requests at any time. Each status read data block has the size of a page (4096 bytes) and needs to be placed in one page. Instead of having a kmem_cache for allocating page sized chunks, use mempool_create_page_pool to create a mempool returning pages and remove the zfcp kmem_cache.

2011-02-24[SCSI] bnx2i: fix null ptr ref in conn get paramMike Christie1-23/+22
bnx2i has some checks to try and make sure the ep is not destroyed while the addr/port is getting read. However, if after this check: if (!(bnx2i_conn && bnx2i_conn->ep && bnx2i_conn->ep->hba)) goto out; bnx2i_conn->ep is cleared by ep_disconnect then we will oops.

2011-02-24[SCSI] iscsi class: add callout to get iscsi_endpoint valuesMike Christie2-2/+39
For drivers using the ep callbacks the addr and port are attached to the endpoint instead of the conn. This adds a callout to the iscsi_transport to get ep values. It also adds locking around the get param call to make sure that ep_disconnect does not free the LLD's ep interconnect structs from under us (the ep has a refcount so it will not go away but the LLD may have structs from other subsystems that are not allocated in the ep so we need to protect them from getting freed).
