    [SCSI] megaraid_sas: fix 64 bit sense pointer truncation

has caused a problem for 32bit programs with 64bit os -

http://bugzilla.kernel.org/show_bug.cgi?id=15001

fix by converting the user space 32bit pointer to a 64 bit one when
needed.

[SCSI] fcoe: Only rmmod fcoe.ko if there are no active connections

2010-02-17T15:57:05+00:00

Currently we're gracefully tearing down each active connection
when fcoe.ko is removed. We shouldn't allow the user to destroy
connections by removing the module. We should force the user to
destroy each connection and then the module can be removed.

This patch makes it so a refrerence count on the module is taken
each time a fcoe_interface is created. The reference count
is dropped when the fcoe_interface is destroyed. This makes it
so that module_exit() doesn't get called unless all fcoe_interfaces
have been destroyed.

This patch leaves the removal of interfaces in the module_exit
routine so that if the user does a 'rmmod -f' we'll clean everything
up before removing the module.

The module_put line was put before the out_putdev goto line because
we should only be decrementing the reference count if a
fcoe_interface is actually destroyed. If we can't find the netdev
or the fcoe_interface then it's assumed that something else has
destroyed the fcoe_interface and it would have decremented the
reference count at that time.

[SCSI] libfcoe: Send port LKA every FIP_VN_KA_PERIOD secs.

2010-02-17T15:57:03+00:00

libfcoe module doesnt send port keep alive every
FIP_VN_KA_PERIOD due to improper assignment of timeout value.
Update the port_ka_time appropriately by incrementing it by
FIP_VN_KA_PERIOD in fcoe_ctlr_timeout(), so that the link_work
is scheduled to send the port LKA.

[SCSI] libfc: Don't assume response request present.

2010-02-17T15:57:01+00:00

Fix NULL pointer dereference crash occurs in fc_lport_bsg_request()
for bsg requests that do not contain a response request.
Specifically, FC_BSG_HST_ADD_RPORT and FC_BSG_HST_DEL_RPORT bsg
requests are not guaranteed to include a response request.

[SCSI] libfc: Fix e_d_tov ns -> ms scaling factor in PLOGI response.

2010-02-17T15:56:59+00:00

Both PLOGI and RTV response processing conditionally scale e_d_tov,
but use different scaling factors.  The scaling factor is correct in
RTV response processing.  Bring PLOGI e_d_tov scaling in line with RTV
common service parameter inspection.

[SCSI] libfc: call ddp setup for only FCP reads to avoid accessing junk fsp pointer

2010-02-17T15:56:57+00:00

Adds check to call fc_fcp_ddp_setup for only FCP read cmds to avoid
accessing junk fsp pointer at least in ESX since non FCP frame had
junk fsp value, though fsp is implicitly initialized to null
by __alloc_skb but with this patch no more relying on fsp
initialized to null value and hitting junk fsp ptr access.

Removes fsp pointer checking in fc_fcp_ddp_setup as this is not
needed any more since its only caller for FCP read will always
have a valid fsp.

[SCSI] iscsi_tcp regression: remove bogus warn on in write path

2010-02-17T15:55:22+00:00

An empty r2tqueue is a valid state. It just means that we have
processed all that there was to do. This patch removes the WARN_ON
that was added when the kfifo changes were merged.

[SCSI] qla2xxx: Obtain proper host structure during response-queue processing.

2010-02-08T19:45:55+00:00

Original code incorrectly assumed only status-type-0
IOCBs would be queued to the response-queue, and thus all
entries would safely reference a VHA from the IOCB
'handle.'
