            Bug ID: 81861
           Summary: mvsas.ko v0.8.16 error messages and kernel crashes
                    attaching 4 SATA drives to specific HP SAS expander
                    ports
           Product: SCSI Drivers
           Version: 2.5
    Kernel Version: 3.16.0-031600rc6
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: Other
          Assignee: scsi_drivers-other@kernel-bugs.osdl.org
          Reporter: linux-ide@crashplan.pro
        Regression: No

The issues are (1) error messages and (2) kernel crashes when attaching 4
drives (1 SFF SAS cable) to specific ports of a SAS expander.

The issue is only tested with HP SAS port expander (PMC Sierra PM8005 chip)
running firmware 2.08. This expander has 36/4=9 SAS ports.
1 port of type SFF-8088, labelled 1C on the PCB.
8 port of type SFF-8087, labelled 2C till 9C on the PCB.
Port “1C” is connected to a Supermicro SAS2LP-MV8, Marvell 88SE9485 based chip,
lspci output is inserted below.

The issue is not always identical. When attaching the 4 drives to different
port numbers on the port multiplier, this is what happens in this order:
2C, 3C, 4C = ok
5C         = error
6C, 7C, 8C = kernel crash
9C         = error

After that first run from port 2 till 9, the issue seems more random:
9C = kernel crash
4C = kernel crash
3C = error
9C = error
7C = kernel crash
3C = error
2C = ok
4C = kernel crash

The “error message” on ports 5C and 9C is:
scsi 5:0:4:0: Failed to get diagnostic page 0x8000002
scsi 5:0:4:0: Failed to bind enclosure -19

====
Most testing is done with Ubuntu 14.04.1 running Ubuntu’s supplied mainline
kernel 3.16.0-rc6.

A Highpoint Rocket 2720SGL controller (also a Marvell 9485 based chip as far as
I know) ran with identical SAS expander and disk drives and power supply
without errors/crashes using the Highpoint 4.0.0.1528N driver (mv94xx.ko) on
Debian 6.0.6/kernel 2.6.32-46.

--- Comment #3 from linux-ide@crashplan.pro ---
Because Ubuntu doesn't provide debug symbols for their mainline kernel builds
<http://comments.gmane.org/gmane.linux.ubuntu.devel.kernel.general/40661> I am
reverting back to their kernel version 3.13.0-24.46

That results in a kernel crash on port 8C: 
BUG: unable to handle kernel NULL pointer dereference at 0000000000000255

Trying to debug mvs_task_prep with the help of the tutorial at
<http://www.opensourceforu.com/2011/01/understanding-a-kernel-oops/>.

# cat /sys/module/mvsas/sections/.init.text
0xffffffffa00c8000

# cd /lib/modules/3.13.0-24-generic/kernel/drivers/scsi/mvsas

# gdb mvsas.ko

(gdb) add-symbol-file
/usr/lib/debug/lib/modules/3.13.0-24-generic/kernel/drivers/scsi/mvsas/mvsas.ko
0xffffffffa00c8000

(gdb) disassemble mvs_task_prep

Hex to decimal: 0x72e = <+1838>

0xffffffffa00ca81e <+1838>:    mov    0x254(%rbx),%ecx

Thanks to the trick from
<https://blogs.oracle.com/ksplice/entry/8_gdb_tricks_you_should>
(gdb) set substitute-path /build/buildd /home/user/src

(gdb) list *0xffffffffa00ca81e
0xffffffffa00ca81e is in mvs_task_prep
(/build/buildd/linux-3.13.0/drivers/scsi/mvsas/mv_sas.c:471).
Line number 466 out of range;
/build/buildd/linux-3.13.0/drivers/scsi/mvsas/mv_sas.c has 306 lines.

I guess my gdb version 7.7 has a line counting bug according to
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=730630>

A manual approach using
<http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-trusty.git;a=blob;f=drivers/scsi/mvsas/mv_sas.c;h=6c1f223a8e1d335fa7c86a374e470e666e848906;hb=HEAD>:

467         slot = &mvi->slot_info[tag];
468         slot->tx = mvi->tx_prod;
469         del_q = TXQ_MODE_I | tag |
470                 (TXQ_CMD_STP << TXQ_CMD_SHIFT) |
471                 (MVS_PHY_ID << TXQ_PHY_SHIFT) |
472                 (mvi_dev->taskfileset << TXQ_SRS_SHIFT);
473         mvi->tx[mvi->tx_prod] = cpu_to_le32(del_q);

Results that "(MVS_PHY_ID << TXQ_PHY_SHIFT)" is the offending code.

How should that be patched?

Thats not a sensible resolution, it can't be faulting on that line.

--- Comment #6 from linux-ide@crashplan.pro ---
When connecting just a single 4 drive group to the good ports (for example 2C)
of the external PCIe expander card:
cold boot = doesn't detect any of the 4 PUIS drives
warm boot = does detect all 4 PUIS drives

When powering up using the warm boot method there don't seem to be errors
reported by smartctl neither sg_ses.

However this cold boot issue might be a different issue from this kernel crash.
According to debug messages first a "Set Features" (0xEF) is being sent. My
guess is that this set features issues subcommand (0x07): spin up media.

And later on the "Identify Device" (0xEC) is sent.


When I correctly read the Hitachi specification the Spin Up (Set Features)
should be sent after "Drive Identify". For this Hitachi HDS5C3020BLE630 the
Drive_Identify (# sg_sat_identify -v /dev/sdb) word 2 outputs "738c" (hex),
which translates to specification "Need Set Feature for spin-up after power-up
Identify Device is complete" according to HGST specification page 127.

Is there a boot parameter (or similar way) to load the mvsas driver without
sending the "Set Features" (0xEF) command?

re: Thats not a sensible resolution, it can't be faulting on that line.

Another try using a newer version of package gdb-minimal (Ubuntu 7.7-0ubuntu3.2
from trusty-proposed) gives these identical results where address <+1838> maps
to line 471 in mvsas.c and that points to "(MVS_PHY_ID << TXQ_PHY_SHIFT) |".

Another test round to see whether there is a difference in crash whether using
cold or warm boot:
5C + cold boot = mvs_task_prep+0x72e/0xd50 [mvsas]
5C + warm boot = mvs_task_prep+0x72e/0xd50 [mvsas]
6C + cold boot = mvs_task_prep+0x72e/0xd50 [mvsas]
6C + warm boot = mvs_task_prep+0x72e/0xd50 [mvsas]
7C + cold boot = mvs_task_prep+0x72e/0xd50 [mvsas]
7C + warm boot = mvs_task_prep+0x72e/0xd50 [mvsas]
8C + cold boot = mvs_task_prep+0x72e/0xd50 [mvsas]
8C + warm boot = mvs_task_prep+0x72e/0xd50 [mvsas]
9C + cold boot = mvs_task_prep+0x72e/0xd50 [mvsas]
9C + warm boot = mvs_task_prep+0x72e/0xd50 [mvsas]

In cases 6C, 7C and 9C the r8169 nic 
doesn't come up after the first automatic reboot after cold boot ("Waiting for
network configuration..." and "Waiting up to 60 more seconds for network
configuration...")
   does come up after the second automatic reboot after cold boot

   0xffffffffa01c481e <+1838>:    mov    0x254(%rbx),%ecx

is loading an offset from something. It can't be line 471.

It could be line 472, or could be 468. but the offset looks way too big to be
either unless its been optimised somewhat. It's not always entirely accurate.

At this point what might be useful is to add lines between then and rebuild ...
ie



                printk("[");
467        slot = &mvi->slot_info[tag];
                printk("%d ", tag);
468        slot->tx = mvi->tx_prod;
                printk("%p ",  slot);
469        del_q = TXQ_MODE_I | tag |

472            (mvi_dev->taskfileset << TXQ_SRS_SHIFT);
                printk("%d", mvi->tx_prod]);
473        mvi->tx[mvi->tx_prod] = cpu_to_le32(del_q);
                printk("]\n");

and try again. When it dies just before the oops you should have  lines of the
form

[num num num]

the final one of which is incomplete. Where it ends tells us where it died and
the values may even give
us a guess at why. If the final [ .. ] sequence is complete then it crashed
somewhere else in the routine and gdb is confused.

By the way:

printk("%d", mvi->tx_prod]);

was changed to:

printk("%d", mvi->tx_prod);

The square bracket after tx_prod was removed.

When line-by-line dumping the called constants/vars from:
469        del_q = TXQ_MODE_I | tag |
470            (TXQ_CMD_STP << TXQ_CMD_SHIFT) |

472            (mvi_dev->taskfileset << TXQ_SRS_SHIFT);

using the prepended statements:
        printk("slot=%p ", slot);
        printk(KERN_INFO "TXQ_MODE_I=%d ", TXQ_MODE_I);
        printk(KERN_INFO "tag=%d ", tag);
        printk(KERN_INFO "TXQ_CMD_STP=%d ", TXQ_CMD_STP);

the kernel crash occurs after printing "TXQ_CMD_SHIFT" or when trying to output

Any suggestions why accessing "MVS_PHY_ID" leads to the kernel NULL pointer

1. Although MVS_PHY_ID looks like a constant, it's really not:
#define MVS_PHY_ID (1U << sas_phy->id)

2. This fault:
[   32.271218] BUG: unable to handle kernel NULL pointer dereference at 0000000000000255
(although 255 looks like a decimal number 0xff, it's really hex 0x255)

at this line:
   0xffffffffa01c481e <+1838>:	mov    0x254(%rbx),%ecx

implies that rbx contains 1, so 0x254 + 1 = 0x255.

3. pahole drivers/scsi/mvsas/mv_sas.o
shows there are two structures with fields at offset 596:
* asd_sas_phy.id
* asd_sas_port.sas_addr[8]

4. objdump -drS drivers/scsi/mvsas/mv_sas.o
shows only a few lines with 0x254(%something), one of which
is the del_q line you've identified:

mvs_task_prep_ata(struct mvs_info *mvi, struct mvs_task_exec_info *tei):
        struct sas_ha_struct *sha = mvi->sas;
        struct sas_task *task = tei->task;
        struct domain_device *dev = task->dev;
        struct sas_phy *sphy = dev->phy;
        struct asd_sas_phy *sas_phy = sha->sas_phy[sphy->number];

        ...
        del_q = TXQ_MODE_I | tag |

                (MVS_PHY_ID << TXQ_PHY_SHIFT) |
                (mvi_dev->taskfileset << TXQ_SRS_SHIFT);
        mvi->tx[mvi->tx_prod] = cpu_to_le32(del_q);

MVS_PHY_ID =
sas_phy->id =

mvi->sas->sas_phy[dev->phy->number] =
mvi->sas->sas_phy[task->dev->phy->number]->id
mvi->sas->sas_phy[tei->task->dev->phy->number]->id

Looking at the offsets reported by pahole, that means:
%rdi->56->344[%rsi->0->0->56->688]->254

mvi->sas->sas_phy is a pointer to a pointer:
struct sas_ha_struct {
...
        struct asd_sas_phy * *     sas_phy;              /*   344     8 */

You might look for somewhere that could accidentally
be setting sas_phy[something] to a for loop index,
with a typecast hiding the problem from the compiler.
Or, the phy->number value being passed might be
out of range; if there were discovery errors, something
might not have been initialized like this function expects.

--- Comment #17 from Leon Woestenberg <sidebranch.linux@gmail.com> ---

With TXQ_PHY_SHIFT being 12, and TXQ_CMD_SHIFT being 29, it seems the PHY
one-bit-hot coding appears in bits 12 through 28 inclusive.

I.e. 16 bits or PHY ID's are supported.

The register transmitted to the controller seems a 32-bit fixed register, so
this seems a hardware limitation rather than software driver limitation.

469        del_q = TXQ_MODE_I | tag |
470            (TXQ_CMD_STP << TXQ_CMD_SHIFT) |
471            (MVS_PHY_ID << TXQ_PHY_SHIFT) |
472            (mvi_dev->taskfileset << TXQ_SRS_SHIFT);
                printk("%d", mvi->tx_prod]);
473        mvi->tx[mvi->tx_prod] = cpu_to_le32(del_q);

Remaining question: how is this supposed to fly with port expanders where PHY
ID's get >16?

The problem was introduced with this patch :
commit 7c237c5f6d5c62724ccd82aecdcd1fd9bd71dc75
Author: Xiangliang Yu <yuxiangl@marvell.com>
Date:   Wed Jan 30 00:25:53 2013 +0800

    [SCSI] mvsas: fixed timeout issue when removing module


The offending line :
    (MVS_PHY_ID << TXQ_PHY_SHIFT)
was before :
    (sas_port->phy_mask << TXQ_PHY_SHIFT)

Reverting the patch corrects the problem for me (kernel 3.18.1)

There seems to be various issues with this driver. After reverting that commit,
I can load the driver, but insmod takes a long time to return. One time was
about 3mins, the other times I gave up waiting and rebooted after 5mins. I'm
using an Areca ARC-1320, so I've ended up downgrading my kernel and using the
proprietary driver just so that it works.

I should add, this was with kernel 3.18.3 and I'll attach the dmesg section
from insmod.

On the Linux-scsi mailing list a possible patch was introduced that has been
tested to fix another appearance of the mvsas port expander mvs_task_prep
panic.

In that case the resulting panics for the combination mvsas + port expander +
SATA drives were:
1. RIP  [<ffffffffa00cd7ed>] mvs_task_prep+0x78d/0xe40 [mvsas]
2. RIP  [<ffffffffa00bd90f>] mvs_task_prep+0x73f/0xd50 [mvsas]
3. RIP  [<ffffffffa006f5b0>] mvs_task_prep_ata+0x80/0x3a0 [mvsas]
4. RIP: 0010:[<ffffffffa00f1877>]  [<ffffffffa00f1877>]
mvs_task_exec.isra.13+0x827/0xf10 [mvsas]

Well, that narrows it down.  It looks like there's a longstanding bug in
mvs_task_prep_ata() where the physical PHY field is populated by taking
an index through the HBA phy table.  This field is ignored for STP but
the phy table is too small and it uses the expander phy number to index
it (hence the GPF as we fall off the end of the phy table trying to
dereference sas_phy->id).

This should fix the problem.

dmesg output after loading module

Just tested the driver from linux-stable since that patch has been merged.
After loading, I get a bunch of "failed to IDENTIFY" errors, then an oops and
insmod never returned (so far been 15mins and nothing new in dmesg).

OK, need the bit before this log showing the expander configuration.

My system was oopsing, pre patch.  I am happy to give you the full

Apparently this driver has never worked with my card (at least with
SATA drives, haven't got any SAS drives to test with). I tested the
first release that had the PCI ID added (2.6.32-rc4) and get the same
result: no drives detected. I also tested 4.2.2 and that throws
warnings on unloading the driver (full log attached).
