2014-07-18scsi: use 64-bit LUNsHannes Reinecke1-11/+11
The SCSI standard defines 64-bit values for LUNs, and large arrays employing large or hierarchical LUN numbers become more and more common. So update the linux SCSI stack to use 64-bit LUN numbers.

2014-03-15[SCSI] libiscsi: Reduce locking contention in fast pathShlomo Pongratz1-2/+2
Replace the session lock with two locks, a forward lock and a backwards lock named frwd_lock and back_lock respectively. The forward lock protects resources that change while sending a request to the target, such as cmdsn, queued_cmdsn, and allocating task from the commands' pool with kfifo_out. The backward lock protects resources that change while processing a response or in error path, such as cmdsn_exp, cmdsn_max, and returning tasks to the commands' pool with kfifo_in. Under a steady state fast-path situation, that is when one or more processes/threads submit IO to an iscsi device and a single kernel upcall (e.g softirq) is dealing with processing of responses without errors, this patch eliminates the contention between the queuecommand()/request response/scsi_done() flows associated with iscsi sessions. Between the forward and the backward locks exists a strict locking hierarchy. The mutual exclusion zone protected by the forward lock can enclose the mutual exclusion zone protected by the backward lock but not vice versa. For example, in iscsi_conn_teardown or in iscsi_xmit_data when there is a failure and __iscsi_put_task is called, the backward lock is taken while the forward lock is still taken. On the other hand, if in the RX path a nop is to be sent, for example in iscsi_handle_reject or __iscsi_complete_pdu than the forward lock is released and the backward lock is taken for the duration of iscsi_send_nopout, later the backward lock is released and the forward lock is retaken. libiscsi_tcp uses two kernel fifos the r2t pool and the r2t queue. The insertion and deletion from these queues didn't corespond to the assumption taken by the new forward/backwards session locking paradigm. That is, in iscsi_tcp_clenup_task which belongs to the RX (backwards) path, r2t is taken out from r2t queue and inserted to the r2t pool. In iscsi_tcp_get_curr_r2t which belong to the TX (forward) path, r2t is also inserted to the r2t pool and another r2t is pulled from r2t queue. Only in iscsi_tcp_r2t_rsp which is called in the RX path but can requeue to the TX path, r2t is taken from the r2t pool and inserted to the r2t queue. In order to cope with this situation, two spin locks were added, pool2queue and queue2pool. The former protects extracting from the r2t pool and inserting to the r2t queue, and the later protects the extracing from the r2t queue and inserting to the r2t pool.

2013-01-29[SCSI] qla4xxx: Fix MBOX intr switching from polling to intr mode for ISP83XXVikas Chaudhary1-7/+10
Issue: Mailbox command timed out after switching from polling mode to interrupt mode. Events:- 1. Mailbox interrupts are disabled 2. FW generates AEN and at same time driver enables Mailbox Interrupt 3. Driver issues new mailbox to Firmware In above case driver will not get AEN interrupts generated by FW in step #2 as FW generated this AEN when interrupts are disabled. During the same time driver enabled the mailbox interrupt, so driver will not poll for interrupt. Driver will never process AENs generated in step #2 and issues new mailbox to FW, but now FW is not able to post mailbox completion as AENs generated before are not processed by driver. Fix: Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX. This will make sure we process all Mailbox and AENs in interrupt mode.
