| * [SCSI] iscsi class, iscsi_tcp, iser, qla4xxx: add netdevname sysfs attrMike Christie2007-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iSCSI must support software iscsi (iscsi_tcp, iser), hardware iscsi (qla4xxx), and partial offload (broadcom). To be able to allow each stack or driver or port (virtual or physical) to be able to log into the same target portal we use the initiator tuple [[HWADDRESS | NETDEVNAME], INITIATOR_NAME] and the target tuple [TARGETNAME, CONN_ADDRESS, CONN_PORT] to id a session. This patch adds the netdev name, which is used by software iscsi when it binds a session to a netdevice using the SO_BINDTODEVICE sock opt. It cannot use HWADDRESS because if someone did vlans then the same netdevice will have the same mac and the initiator,target id will not be unique.

| * [SCSI] libiscsi: make can_queue configurableMike Christie2007-06-02
| | | | | | | | | | | | | | | | | | | | | | | | This patch allows us to set can_queue and cmds_per_lun from userspace when we create the session/host. From there we can set it on a per target basis. The patch fully converts iscsi_tcp, but only hooks up ib_iser for cmd_per_lun since it currently has a lots of preallocations based on can_queue.

| * [SCSI] libiscsi: fix iscsi cmdsn allocationMike Christie2007-06-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cmdsn allocation and pdu transmit code can race, and we can end up sending a pdu with cmdsn 10 before a pdu with 5. The target will then fail the connection/session. This patch fixes the problem by delaying the cmdsn allocation until we are about to send the pdu. This also removes the xmitmutex. We were using the connection xmitmutex during error handling to handle races with mtask and ctask cleanup and completion. For ctasks we now have nice refcounting and for the mtask, if we hit the case where the mtask timesout and it is floating around somewhere in the driver, we end up dropping the session. And to handle session level cleanup, we use the xmit suspend bit along with scsi_flush_queue and the session lock to make sure that the xmit thread is not possibly transmitting a task while we are trying to kill it.

| * [SCSI] iscsi class, iscsi_tcp, ib_iser: add sysfs chap fileMike Christie2007-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patches add sysfs files for the chap settings to the iscsi transport class, iscsi_tcp and ib_iser. This is needed for software iscsi because there are times when iscsid can die and it will need to reread the values it was using. And it is needed by qla4xxx for basic management opertaions. This patch does not hook in qla4xxx yet, because I am not sure the mbx command to use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For iscsi root boot, software iscsi needs to know what the BIOS/OF initiator used for the initiator name so this puts it in sysfs for userspace to be able to pick up.

| * | IPoIB: Recycle loopback skbs instead of freeing and reallocatingRoland Dreier2007-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | InfiniBand HCAs replicate multicast packets back to the QP that sent them if that QP is attached to the destination multicast group. This means that IPoIB multicasts are often replicated back to the receive queue of the interface that generated them. To avoid confusing the network stack, we drop these duplicates within the IPoIB driver. However, there's no reason to free the skb that received the duplicate and then immediately allocate a new skb to post to the receive queue. We can be more efficient and just repost the same skb.
