* libiscsi: return new error code when nop times outMike Christie2014-08-011-0/+1
| | | | | | | | | | | | When a iscsi nop as ping timedout we were failing with the common connection error code, ISCSI_ERR_CONN_FAILED. This patch adds a new error code for this problem so can properly track/distinguish in userspace.

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This adds two new attrs used for creating initiator ports and binding sessions to hardware. The session level initiatorname: Since bnx2i does a scsi_host per host device, we need to add the iface initiator port settings on the session, so we can create multiple initiator ports (each with different inames) per device/scsi_host. The current iname reflects that qla4xxx can have one iname per hba, and we are allocating a host per session for software. The iname on the host will remain so we can export and set the hba level qla4xxx setting. The ifacename attr: To bind a session to a some peice of hardware in userspace we maintain some mappings, but during boot or iscsid restart (iscsid contains the user space part of the driver) we need to be able to figure out which of those host mappings abstractions maps to certain sessions. This patch adds a ifacename attr, which userspace can set to id the host side of the endpoint across pivot_roots and iscsid restarts.

Software iscsi/iser will follow the same behabior as before where it allcoates a host per session, but in the future iser will probably look more like bnx2i where the host's parent is the hardware (rnic for iser and for bnx2i it is the nic), because it does not use a socket layer like how iscsi_tcp does.

| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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] iscsi class, iscsi_tcp, ib_iser: add sysfs chap fileMike Christie2007-06-011-0/+9
| | | | | | | | | | | | | | 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.
