[PATCH V2 05/18] be2iscsi: Fix freeing CXN specific driver resources.

[Jayamohan Kallickal]

 Free CXN specific resource held by driver when login redirection
 or connection retry happens. Login redirection was failing
 because WRB/SGL were not allocated from the CID on which
 doorbell was rung.

Fixed the issue raised by MikeC

[PATCH V2 08/18] be2iscsi: Fix displaying the FW Version from driver.

[Jayamohan Kallickal]

 The mgmt_hba_attributes structure declared was not proper and
 because of that the FW response returned for the MBX_CMD was not
 matching. This issue went unnoticed as mgmt_hba_attribs structure
 members were never used in the code path.

 This fix of displaying the FW version had to change the mgmt_hba_attrib
 structure also. The latest driver will also work with the older FW as
 the issue was in the driver declaration.

[PATCH V2 11/18] be2iscsi : Fix the NOP-In handling code path

[Jayamohan Kallickal]

 When target send a NOP-IN with valid TTT, driver issues a NOP-OUT
 and the task was not freed from driver. The task list available for
 the session used to run out, and as no more task list were available
 no more iSCSI commands were exchanged on that session.
 This patches fixed the issue, by calling iscsi_put_task.

[PATCH V2 12/18] be2iscsi: Fix dynamic CID allocation Mechanism in driver

[Jayamohan Kallickal]

 Number of CID assigned to a function from adapter can be dynamic. The CID count
 for each function was fixed number before. Code Fix done so that adapters with
 fixed/dynamic CID count will work with the driver.

[PATCH V2 15/18] be2iscsi: Fix the session cleanup when reboot/shutdown happens

[Jayamohan Kallickal]

 During reboot/shutdown cycle, the active sessions were not updated.
 In iSCSI Boot case, the boot session was alive and this fix informs
 that the machine is going down, so no more ops happens on that session.

I am not sure how this is working or what it fixes. During 
shutdown/reboot when the pci_driver shutdown callback is called, without 
the patch what is happening? Does the host shutdown cause iscsid to try 
and recover the session and that causes a shutdown/reboot hang?

I think you want to use ISCSI_ERR_INVALID_HOST. That would cause a clean 
shutdown of the sessions if iscsid is still up at that time. This would 
cause ep_disconnect to get called and a logout pdu to get sent.

ISCSI_ERR_CONN_FAILED just causes recovery to start (ep_disconnect will 
run if the ep is up and we will try to reconnect).

James,

I am looking into this issue raised by MikeC and would send a patch later to resolve this.

 So, I would like to withdraw this patch (15/18) now.

Thanks

[PATCH V2 16/18] be2iscsi: Fix possible reentrancy issue in be_iopoll

[Jayamohan Kallickal]

From: Shlomo Pongratz <shlomop@mellanox.com>

 The driver creates "NAPI" context per core which is fine,
 however the above routine declares the ret variable as static!
 Thus there is only one instance of this variable!
 When this routine is called from more than one thread of execution,
 than the result is unpredictable.

         static unsigned int ret;
         .....

         ret = beiscsi_process_cq(pbe_eq);
                 <--------Another thread can enter here and change "ret".
         if (ret < budget) {
                ....
         }
                 <--------Another thread can enter here and change "ret".
         return ret;

 Fix - remove the "static"

The rule here is that this needs to be Signed-off-by: from you because
you sent the patch to me (signoffs follow the transmission path for the
patch).  If you just see the patch on the list and want me to apply it,
you give me an Acked-by, but if you actually pick the patch up and send
it to me it must have a signed-off-by.

I assumed your consent and changed the tag.

[PATCH V2 17/18] be2iscsi: Fix issue in passing the exp_cmdsn and max_cmdsn

[Jayamohan Kallickal]

 Command Window value from the CQE was used to calculate the
 max_cmdsn for that session.The command window value extracted
 for SKH-R adapter was not proper. The value was extracted from
 BE adapter completion event. Fixed the issue by getting the
 cmd_wnd value from SKH-R CQE.

 The exp_cmdsn and max_cmdsn values were not converted to BE format
 before calling the __iscsi_complete_pdu(). Fixed the issue of converting
 to BE format.
