We submited 4.12 driver to upstream which accepted by main stream 2.6.33. Is
there available to try 4.12?

Thanks,

Bo Yang

Hello , 
so what I have done  :

I copied megaraid directory from 2.6.33-rc3  and compiled module 

here is my Makefile 
obj-$(CONFIG_MEGARAID_MM)       += megaraid_mm.o
obj-$(CONFIG_MEGARAID_MAILBOX)  += megaraid_mbox.o
obj-$(CONFIG_MEGARAID_SAS)      += megaraid_sas.o
KDIR := /lib/modules/2.6.31.11-grsec/build
PWD := $(shell pwd)
default:
        $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) CONFIG_DEBUG_SECTION_MISMATCH=y
modules

and here is the make's output 

/home/pkg/megaraid/megaraid# make 
make -C /lib/modules/2.6.31.11-grsec/build SUBDIRS=/home/pkg/megaraid/megaraid

I still get this messages 
megasas: Failed to copy out to user sense data

the same was for 4.17 version which I got from dell site .

dmesg is attached .

and what does this message mean ?
is it harmless ? 

Thank you .
Regards , 
Alex

This is a "me too" post...

I have a problem since the commit (SCSI: megaraid_sas: fix 64 bit sense pointer
truncation) with several Dell 2950 Servers. It happens both on the Perc 5/i and
the Perc 6/i controllers. All of these machines have 8GB RAM and are running
x86_64 kernels (currently 2.6.32.2). I always get messages like this in the
Kernel Log (plus on the console, which is VERY annoying:
[69274.972038] megasas: Failed to copy out to user sense data
[69274.972182] megasas: Failed to copy out to user sense data
[71168.206030] megasas: Failed to copy out to user sense data
[71168.206175] megasas: Failed to copy out to user sense data

It happens about 2-5 times per hour, most of the time several of those errors
(2-3) are reported in close timely vicinity, like within a few seconds. Other
than this these servers seem to be stable, so i guess it is a spurious message
caused by above commit. Replacing megaraid_sas.c with the version from Kernel
2.6.32 cures the problem.

I've also tried using version v00.00.04.12-rc1 of megaraid_sas.c (and .h)
from Kernel 2.6.33-rc3 and i can confirm that it shows the same problems
on my hardware:
[70120.567013] megasas: Failed to copy out to user sense data
[70120.576426] megasas: Failed to copy out to user sense data
[70120.576869] megasas: Failed to copy out to user sense data
[70120.587822] megasas: Failed to copy out to user sense data

Created an attachment (id=24890)
 --> (http://bugzilla.kernel.org/attachment.cgi?id=24890)
patch to handle compat apps

The issue is probably caused by a 32bit application in a 64bit os. The 'open
manage' here uses a 32bit pointer and the driver after the 'SCSI: megaraid_sas:
fix 64 bit sense pointer truncation' works with it as if it was a 64bit
pointer.
The attached patch handles the situation on my test box.

That means that you no more see the 
"megasas: Failed to copy out to user sense data" 
or have you also verified that the management software works as expected?

Yes , that means that I don't see this message any more , 
and what does it mean "Failed to copy out to user sense data" ?
> or have you also verified that the management software works as expected?
And I still can retrieve information with MegaCli utility , should I check
something special ?

That means that the function copy_to_user in the driver failed and the ioctl
returned EFAULT. Usually programs can cope with that, but it could mean that
they are not able to collect informations from that device.

I'm not sure with MegaCli, what I meant here is the Dell management sw 'Open
Manage', so if you can check if this sw can collect info from  megaraid driver.

I guess it is ok , 
OMSA is 6.0.1-8 . For example 
omreport storage vdisk 
omreport storage pdisk controller=0 
works as expected .

Applied the patch on all our systems which were exhibiting this bug. The error
message in dmesg is gone now. Dell OMSA still works as expected, including
omreport and the Dell OpenManage Web Application.
Thanks for the fast fix!
