* scsi_dh: Verify "dev" is a sdev before accessing it.Chandra Seetharaman2008-07-16
| | | | | | | | | | | Before accessing the device data structure in hardware handlers, make sure it is a indeed a sdev device. Yinghai Lu <yhlu.kernel@gmail.com> found the bug on Jul 16, 2008, and later tested/verified the following fix.

| | | | | | | | | | | | | | | | | | | | The sym53c8xx driver, for some reason, seems to mostly re-implement linux/list.h with added bogosity.

| * [SCSI] fix locking in host use of blk_plug_device()James Bottomley2008-07-12
| | | | | | | | | | | | | | | | | | | | | | | | scsi_lib.c:scsi_host_queue_ready() plugs the device with incorrect locking. It should actually have the queue lock held, but it's holding the host lock. Fix this by eliminating the call. The host ready has no need to plug the queue because if it returns 0 in scsi_request_function control transfers to not_ready which acquires the queue lock and plugs the device if its at zero depth.

| * [SCSI] libiscsi, iscsi_tcp, ib_iser: fix setting of can_queue with old tools.Mike Christie2008-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes two bugs that are related. 1. Old tools did not set can_queue/cmds_max. This patch modifies libiscsi so that when we add the host we catch this and set it to the default. 2. iscsi_tcp thought that the scsi command that was passed to the eh functions needed a iscsi_cmd_task allocated for it. It only needed a mgmt task, and now it does not matter since it all comes from the same pool and libiscsi handles this for the drivers. ib_iser had copied iscsi_tcp's code and set can_queue to its max - 1 to handle this. So this patch removes the max -1, and just sets it to the max. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Seen: kernel BUG at arch/i386/lib/usercopy.c:872 under a 2.6.18-8.el5 kernel. Traced it to a garbage-in/garbage-out ioctl condition in the aacraid driver. Adaptec's special ioctl scb passthrough needs to check the validity of the individual scatter gather count fields to the maximum the adapter supports. Doing so will have the side effect of preventing copy_from_user() from bugging out while populating the dma buffers. This is a hardening effort, issue was triggered by an errant version of the management tools and thus the BUG should not be seen in the field.

| * [SCSI] libiscsi, iser, tcp: remove recv_lockMike Christie2008-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recv lock was defined so the iscsi layer could block the recv path from processing IO during recovery. It turns out iser just set a lock to that pointer which was pointless. We now disconnect the transport connection before doing recovery so we do not need the recv lock. For iscsi_tcp we still stop the recv path incase older tools are being used. This patch also has iscsi_itt_to_ctask user grab the session lock and has the caller access the task with the lock or get a ref to it in case the target is broken and sends a tmf success response then sends data or a response for the command that was supposed to be affected bty the tmf.

| * [SCSI] iscsi class: Add session initiatorname and ifacename sysfs attrs.Mike Christie2008-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
