* [SCSI] libiscsi: add task aborted stateMike Christie2009-05-23
| | | | | | | | | | | | If a task did not complete normally due to a TMF, libiscsi will now complete the task with the state ISCSI_TASK_ABRT_TMF. Drivers like bnx2i that need to free resources if a command did not complete normally can then check the task state. If a driver does not need to send a special command if we have dropped the session then they can check for ISCSI_TASK_ABRT_SESS_RECOV.

* [SCSI] iscsi: pass ep connect shostMike Christie2009-05-23
| | | | | | | | | | | | | | | | | | | | When we create the tcp/ip connection by calling ep_connect, we currently just go by the routing table info. I think there are two problems with this. 1. Some drivers do not have access to a routing table. Some drivers like qla4xxx do not even know about other ports. 2. If you have two initiator ports on the same subnet, the user may have set things up so that session1 was supposed to be run through port1. and session2 was supposed to be run through port2. It looks like we could end with both sessions going through one of the ports. Fixes for cxgb3i from Karen Xie.

| | * IB/mlx4: Don't overwrite fast registration page list when posting work requestJack Morgenstein2009-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The low-level mlx4 driver modified the page-list addresses for fast register work requests post send to big-endian, and set a "present" bit. This caused problems later when the consumer attempted to unmap the pages using the page-list (using the list addresses which were assumed to be still in CPU-endian order). Fix the mlx4 driver to allocate two buffers and use a private buffer for the hardware-format bus addresses. This patch fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1571>, an NFS/RDMA server crash. The cause of the crash was found by Vu Pham of Mellanox. The fix is along the lines suggested by Steve Wise in comment #21 in bug 1571. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

Fixing this required going over the code and making sure the rexmit entry was properly removed based on the cm_node's state and packet received. Also when receiving a FIN packet, check seq# and make sure there were no errors before calling handle_fin(). Following are the changes done in nes_cm.c: * handle_ack_pkt() needs to return error value, so in case of error, handle_fin() is not called. Some cleanup done while going over the code. * handle_rst_pkt(), handling of cm_node's NES_CM_STATE_LAST_ACK is missing. * process_packet(), in case of FIN only packet is received, call check_seq() before processing. * in handle_fin_pkt(), we are calling cleanup_retrans_entry() for all conditions, even if the packets need to be dropped.

This way NAPI will be disabled when ipoib_drain_cq() is called. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1587>.

In schedule_nes_timer(), we return an error if nes_nic_cm_xmit() returns failure. This is changed to success as skb is being put on the timer routines to be processed later. In send_syn() case, we are indicating connect failure once from nes_connect() and the other when the rexmit retries expires. The other issue is skb->users which we are incrementing before calling nes_nic_cm_xmit() which calls dev_queue_xmit() but in case of failure we are decrementing the skb->users at the same time putting the skb on the rexmit path. Even if dev_queue_xmit() fails, the skb->users is decremented already. We are removing the decrement of skb->users in case of failure from both schedule_nes_timer() as well as from nes_cm_timer_tick(). There is also extra check in nes_cm_timer_tick() for rexmit failure which does a break from the loop is removed. This causes problem as the other nodes have their cm_node->ref_count incremented and are not processed.

| * | RDMA/cma: Create cm id even when IB port is downYossi Etigin2009-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing rdma_resolve_addr(), if the relevant IB port is down, the function fails and the cm_id is not bound to the correct device. Therefore, application does not have a device handle and cannot wait for the port to become active. The function fails because the underlying IPoIB interface is not joined to the broadcast group and therefore the SA does not have a multicast record to take a Q_Key from. The fix is to use lazy Q_Key resolution - cma_set_qkey() will set id_priv->qkey if it was not set, and will be called just before the Q_Key is really required.

| * | RDMA/cma: Use rate from IPoIB broadcast when joining IPoIB multicast groupsYossi Etigin2009-04-01
| |/ | | | | | | | | | | | | | | | | | | | | When joining an IPoIB multicast group, use the same rate as in the broadcast group. Otherwise, if the RDMA CM creates this group before IPoIB does, it might get a different rate. This will cause IPoIB to fail joining to the same group later on, because IPoIB uses strict rate selection.

| * [SCSI] iscsi class: remove host no argument from session creation calloutMike Christie2009-03-13
| | | | | | | | | | | | | | | | | | | | We do not need to have llds set the host no for the session's parent, because we know the session's parent is going to be the host. This removes it from the session creation callback and converts the drivers. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
| * [SCSI] iscsi lib: remove qdepth param from iscsi host allocationMike Christie2009-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | The qdepth setting was useful when we needed libiscsi to verify the setting. Now we just need to make sure if older tools passed in zero then we need to set some default. So this patch just has us use the sht->cmd_per_lun or if for LLD does a host per session then we can set it on per host basis.

| * [SCSI] iscsi lib: have lib create work queue for transmitting IOMike Christie2009-03-13
| | | | | | | | | | | | | | | | | | | | | | We were using the shost work queue which ended up being a little akward since all iscsi hosts need a thread for scanning, but only drivers hooked into libiscsi need a workqueue for transmitting. So this patch moves the xmit workqueue to the lib. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
