This series converts the current bsg usage in the FibreChannel drivers over
to use bsg-lib. SAS will follow once FC is in a good enough shape.
I did take some inspiration from a similar patchset from Mike Christie
dating back to 2011 but it's not a 1:1 copy. Patch 15/16 is heavily based
on his series and attribution is given to him in the commit message.
It is currently regression tested on FCoE using the 'fcns' and
'fcrls' utilities. I'm still trying to figure out how to test the other
LLDDs. So any pointer from the respective maintainers are appreciated
although the LLDD changes are purely mechanical. All they do is change from
'struct fc_bsg_job' to 'struct bsg_job' and corresponding changes in order
to get the series bisectable.
The idea for this change arose when discussing racy sysfs handling the FC
bsg code with Christoph and is a next step in moving all bsg clients to
bsg-lib to eventually clean up the in kernel bsg API.
Changes to v1:
* Reduce the number of individual patches (44 -> 16)
* Fix s390 build failure (forgotten to kill fc_bsg_job from zfcp_ext.h)
* Fix build failure on configs without CONFIG_BLK_DEV_BSGLIB
* Make bsg_job_get() call kref_get_unless_zero() and use it in scsi_transport_fc.c
Changes to v2:
* Add Hannes' Reviewd-by tags
* Address Hannes' comment about kref handling in 8/16
* Move CONFIG_BLK_DEV_BSGLIB dependency to patch 12/16 as per 0day results
Johannes Thumshirn (16):
scsi: Get rid of struct fc_bsg_buffer
scsi: don't use fc_bsg_job::request and fc_bsg_job::reply directly
scsi: fc: Export fc_bsg_jobdone and use it in FC drivers
scsi: Unify interfaces of fc_bsg_jobdone and bsg_job_done
scsi: fc: provide fc_bsg_to_shost() helper
scsi: fc: provide fc_bsg_to_rport() helper
scsi: libfc: don't set FC_RQST_STATE_DONE before calling
fc_bsg_jobdone()
scsi: fc: implement kref backed reference counting
block: add reference counting for struct bsg_job
scsi: change FC drivers to use 'struct bsg_job'
scsi: fc: Use bsg_destroy_job
scsi: fc: use bsg_softirq_done
scsi: fc: use bsg_job_done
block: add bsg_job_put() and bsg_job_get()
scsi: fc: move FC transport's bsg code to bsg-lib
block: unexport bsg_softirq_done() again

1.8.5.6
Don't set FC_RQST_STATE_DONE before calling fc_bsg_jobdone() as
fc_bsg_jobdone() calls blk_complete_requeust() which raises a soft-IRQ that
ends up in fc_bsg_sofirq_done() and fc_bsg_softirq_done() sets the
FC_RQST_STATE_DONE flag.

1.8.5.6
Now that all conversions are done, move the FibreChannel bsg code over to the
bsg library.
This patch is derived from work done by Mike Christie in 2011 [1] but only the
iscsi parts got merged back then.

fc_destroy_bsgjob() and bsg_destroy_job() are now 1:1 copies, so use the

once CONFOG_SCSI_FC_ATTRS is active.

Implement kref backed reference counting instead of rolling our own. This
elimnates the need of the following fields in 'struct fc_bsg_job':
* ref_cnt
* state_flags
* job_lock
bringing us close to unification of 'struct fc_bsg_job' and 'struct bsg_job'.

1.8.5.6
Export fc_bsg_jobdone so drivers can use it directly instead of doing
the round-trip via struct fc_bsg_job::job_done() and use it in the LLDDs.
As we've converted all LLDDs over to use fc_bsg_jobdone() directly,
we can remove the function pointer from struct fc_bsg_job as well.

Don't use fc_bsg_job::request and fc_bsg_job::reply directly, but use

The rational behind this is, in fc_req_to_bsgjob() we're assigning

In the meanwhile I try to reproduce your report here.

Hi Steffen,
Did you have any chance testing this? I hacked fcping to work with non-FCoE
and rports as well and tested with FCoE and lpfc. No problems seen from my
side. I've also pused the series (With this change folded in) to my git
tree at [1] if this helps you in any way.

Thanks a lot,
Johannes

Sorry but I don't quite get you.
If you look at a mixed source assembly listing for fc_host_dispatch() [1] we load
the the offset of 24 from %r12 into %r1 and then the beginning of %r1 into %r2
and crash. So if we now check if job->request_len is smaller than uint32_t we
know we can't have a messagecode in the request and bail out early, instead of
accessing a possible NULL pointer. At least that's my analysis, feel free to
correct me if I'm wrong.

static int fc_bsg_host_dispatch(struct Scsi_Host *shost, struct bsg_job *job)
{
struct fc_internal *i = to_fc_internal(shost->transportt);

So I finally have a test system up and running. I have good and bad news. The
good news is, I can't get the system crashing with my patches, the bad news is
I can't get zfcp_ping and zfcp_show to output something but HBA_STATUS_ERROR
with my patches and without.
And btw, I renamed the branch to fc-bsg-rewrite-v4 in case you want to clone
from it (it has patch 2/16 changed to the v3 submission).
Can you please have a look with your setup?
Thanks,
Johannes

Assuming you run the latest package version on s390x:
Do steps 2 and 3 of the procedure in
http://www.ibm.com/support/knowledgecenter/linuxonibm/com.ibm.linux.z.lhdd/lhdd_t_fcp_api_runappl.html
help?
The only other thing I can think of from the top of my head is that BSG
ioctls are sensitive regarding ABI and I once had the kernel ioctl
return EINVAL due to unmatching kernel-headers and libzfcphbaapi maps
this EINVAL to HBA_STATUS_ERROR because there is no more specifically
suitable HBA constant [old SUSE bugs 834498 and 834500].

I'm going to re-test hopefully within the next few days.

No, I do have a correct /etc/hba.conf:
$ grep libzfcphbaapi /etc/hba.conf
com.ibm.libzfcphbaapi /usr/lib64/libzfcphbaapi.so.0
and bumping the log level via export LIB_ZFCP_HBAAPI_LOG_LEVEL=1 just adds
'(vlib.c:105)_initvlib: libzfcphbaapi.so loaded at Nov 15 15:43:23' to the 1st
line of zfcp_ping output.
Here's the full output:
$ zfcp_ping -v -a 0.0.fc00 -d 0x50050763051b473a

I agree this looks a bit suspicious and I'll add some debugs in the kernel to
see what's going on.

Please ignore my last mails, apparently it's a wise idea to check which user
id one has before running zfcp_ping...
The good news for this is, I can now recreate the crashes you have and thus
have a chance to fix them :-)

So JFTR, I was able to fix the 1 problem introduced by this patch, it's the
follwoing hunk:
@@ -3726,9 +3729,9 @@ fc_req_to_bsgjob(struct Scsi_Host *shost, struct fc_rport *rport,
if (i->f->dd_bsg_size)
job->dd_data = (void *)&job[1];
spin_lock_init(&job->job_lock);
- job->request = (struct fc_bsg_request *)req->cmd;
+ bsg_request = (struct fc_bsg_request *)req->cmd;
job->request_len = req->cmd_len;
- job->reply = req->sense;
+ bsg_reply = req->sense;
job->reply_len = SCSI_SENSE_BUFFERSIZE; /* Size of sense buffer
* allocated */
if (req->bio) {
But as fc_req_to_bsgjob() get's deleted in Patch 15/16 the problem is
re-introduced. Unfortunately the fix isn't as trivial as for 2/16 so I'm still
trying to nail it down.
Thanks,
Johannes
