Mike Christie 8526cb114f [SCSI] iscsi class, qla4xxx: fix sess/conn refcounting when find fns are used
This fixes a bug where the iscsi class/driver did not do a put_device
when a sess/conn device was found. This also simplifies the interface
by not having to pass in some arguments that were duplicated and did
not need to be exported.

Tej Parkash a24058f9c2 [SCSI] qla4xxx: Fixed request queue count manipulation on response path
Issue:
Request queue count holds the information about free space in request queue
which has to be manipulated based on request in and out pointer.
But in driver response path, this count was incremented unconditionally,
which could move req_in pointer beyond req_out pointer.
This scenario leads fw hang during IO.

Solution:
Request queue count manipulation has to be done in IO path only, keeping
req_in and req_out pointer two IOCB count away

In qla4xxx_get_ep_fwdb(), dst_addr is of type struct sockaddr.
We are copying sizeof(struct sockaddr_in6) bytes to dst_addr
which is 12 bytes larger. This will cause memory corruption.
So we change dst_addr to struct sockaddr_storage which is
of 128 byte, large enough to hold sizeof(struct sockaddr_in6).

Vikas Chaudhary 5c19b92ae8 [SCSI] qla4xxx: Fix MBOX intr switching from polling to intr mode for ISP83XX
Issue:
Mailbox command timed out after switching from polling mode to interrupt mode.

Events:-
 1. Mailbox interrupts are disabled
 2. FW generates AEN and at same time driver enables Mailbox Interrupt
 3. Driver issues new mailbox to Firmware

In above case driver will not get AEN interrupts generated by FW in step #2 as
FW generated this AEN when interrupts are disabled. During the same time
driver enabled the mailbox interrupt, so driver will not poll for interrupt.
Driver will never process AENs generated in step #2 and issues new mailbox to
FW, but now FW is not able to post mailbox completion as AENs generated before
are not processed by driver.

Fix:
Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX.
This will make sure we process all Mailbox and AENs in interrupt mode.

Greg Kroah-Hartman 6f03979051 Drivers: scsi: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Lalit Chandivade 20e835b43f [SCSI] qla4xxx: Fix verify boot idx correctly
qla4xxx_verify_boot_idx can falsely report a DDB to be boot target
if ha->pri_ddb_idx and ha->sec_ddb_idx are not initialized correctly.
What this could cause is if there is DDB entry in FLash at index 0, then
qla4xxx_verify_boot_idx would return wrong result as ha->pri_ddb_idx is not
set correctly. Fixed the qla4xxx_get_boot_info to set the ha->pri_ddb_idx and

authentication information is provided using an index into the CHAP region.

In order to support QLogic applications along with iscsiadm, updated the
LLD to not add duplicate CHAP entries in the CHAP region and preserve the
existing CHAP info in the CHAP region in FLASH.
This allows QLogic applications to pre-write the CHAP entries in the
CHAP region.

With iscsiadm, when the CHAP authentication information is sent to the LLD, the
LLD searches for the entry in CHAP region in FLASH, if exists then do not add.
If CHAP entry does not exist then add the CHAP entry in the CHAP region.
