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.

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.

2011-02-24[SCSI] be2iscsi: fix null ptr ref in conn get paramMike Christie3-16/+9
The ep_disconnect function could be freeing the ep while beiscsi_conn_get_param is running. This has the driver use the get ep param callback instead of the get conn param to fix this. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
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. This patches fixes the problem by having the driver use the get_ep_param callback instead of get_conn_param.

2011-02-24[SCSI] iscsi class: add callout to get iscsi_endpoint valuesMike Christie1-2/+37
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).

This has iscsi_tcp use the iscsi_conn_get_addr_param libiscsi function. It also drops the use of the libiscsi session portal buffers, so they can be removed in the next patches. Instead of copying the values at bind time we get them during get() time. If we are not connected userspace will now get -ENOTCONN, so it knows that connection is disconnected instead of a possible stale value.

2011-02-13[SCSI] libsas: convert to libata new error handlerJames Bottomley2-8/+93
The conversion is quite complex given that the libata new error handler has to be hooked into the current libsas timeout and error handling. The way this is done is to process all the failed commands via libsas first, but if they have no underlying sas task (and they're on a sata device) assume they are destined for the libata error handler and send them accordingly. Finally, activate the port recovery of the libata error handler for each port known to the host. This is somewhat suboptimal, since that port may not need recovering, but given the current architecture of the libata error handler, it's the only way; and the spurious activation is harmless.
