Doing some analysis without a crashdump, as it's taking too long.
This looks like a NULL pointer dereference,
if my assembly reading/matching to C is correct.
Would need to understand why/how this
'(struct scsi_cmnd *cmnd)->device' field is NULL.
Analysis
--------
From xmon:
pc: <...>: lpfc_sli4_scmd_to_wqidx_distr+0x30/0x100 [lpfc]
R10 = 0000000000000000 R26 = 0000000000000001
From 'objdump -d /usr/lib/debug/<...>/lpfc.ko',
lpfc_sli4_scmd_to_wqidx_distr = 674b0
lpfc_sli4_scmd_to_wqidx_distr+0x30 = 674e0 (crash)
and
00000000000674b0 <lpfc_sli4_scmd_to_wqidx_distr>:
<...>
674cc: 78 23 9e 7c mr r30,r4
674d0: 78 1b 7f 7c mr r31,r3
<...>
674dc: 10 00 5e e9 ld r10,16(r30)
674e0: 00 00 2a e9 ld r9,0(r10) <<-- (crash)
674e4: 00 00 29 e9 ld r9,0(r9)
<...>
This is the relevant snippet of code:
From Ubuntu 16.04 kernel 4.4.0-22.40 [1]
int lpfc_sli4_scmd_to_wqidx_distr(struct lpfc_hba *phba,
struct lpfc_scsi_buf *lpfc_cmd)
{
struct scsi_cmnd *cmnd = lpfc_cmd->pCmd;
<...>
if (shost_use_blk_mq(cmnd->device->host)) {
<...>
So, back to the assembly, this seems the 2 function parameters
passed by register (r4, r3), loaded into other registers (r30, r31).
674cc: 78 23 9e 7c mr r30,r4
674d0: 78 1b 7f 7c mr r31,r3
Per the load below, r10 is *cmnd, and r30 is *lpfc_cmd; it loads
lpfc_cmd->pCmd, which has offset 16 bytes into struct lpfc_cmd [2]
(after 2 pointers * 8-bytes each, from list_head list [3])
674dc: 10 00 5e e9 ld r10,16(r30)
struct lpfc_scsi_buf {
struct list_head list;
struct scsi_cmnd *pCmd;
<...>
struct list_head {
struct list_head *next, *prev;
};
And the load below hits the crash, because it dereferences r10 (*cmnd)
which is zero:
674e0: 00 00 2a e9 ld r9,0(r10) <<--
(crash)
From xmon:
R10 = 0000000000000000 R26 = 0000000000000001
That deference was for cmnd->device; you can see the load instruction immediately
afterward would further dereference the cmnd->device pointer, for the device->host field,
which has offset 0 into struct scsi_device [4]:
--- this is a confirmantion that the assembly/C matching looks correct.
if (shost_use_blk_mq(cmnd->device->host)) {
struct scsi_device {
struct Scsi_Host *host;

Checking this again today, it occurred to me that the problem is
actually *cmnd == NULL, and dereferencing *cmnd (for cmnd->device)
hits the crash.
Fix submitted upstream:
http://marc.info/?l=linux-scsi&m=146534119707379&w=2
I didn't provide a test kernel because the system was running
regression tests over weekend, and it takes long to reproduce the
problem w/ DLPAR operations -- but the same problem could be
reproduced w/ simpler test-cases (see commit), so I worked it in the
background.
If you keep hitting this, let me know and I'll provide a test kernel.
Hi Mauricio,
Installed the fix and verified. Now am not finding the issue.
Hi Canonical,
Can you consider picking up this fix that has not yet made the
upstream kernel?
It's fairly obvious and trivial, very documented in the commit message
(w/ test-cases), and has been tested successfully here in IBM (also
see commit msg).
http://marc.info/?l=linux-scsi&m=146534119707379&w=2
The adapter vendor's team has not yet reviewed it on the mailing list
(and no other patches for lpfc), so I guess it'll take some time until
this makes in.
Is that possible?
Thanks
Mauricio
