Don't use fc_bsg_job::request and fc_bsg_job::reply directly, but use
helper variables bsg_request and bsg_reply. This will be helpfull when
transitioning to bsg-lib.

Well given what you've wrote for v2 it's kinda expected.

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

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.lhd=
d/lhdd_t_fcp_api_runappl.html
help?
The only other thing I can think of from the top of my head is that BSG=20
ioctls are sensitive regarding ABI and I once had the kernel ioctl=20
return EINVAL due to unmatching kernel-headers and libzfcphbaapi maps=20
this EINVAL to HBA_STATUS_ERROR because there is no more specifically=20
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

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.
[1] Listing:
static int fc_bsg_host_dispatch(struct Scsi_Host *shost, struct bsg_job *job)
{
struct fc_internal *i = to_fc_internal(shost->transportt);
struct fc_bsg_request *bsg_request = job->request;
5d54: e3 10 c0 18 00 04 lg %r1,24(%r12)
struct fc_bsg_reply *bsg_reply = job->reply;
5d5a: e3 b0 c0 20 00 04 lg %r11,32(%r12)
int cmdlen = sizeof(uint32_t); /* start with length of msgcode */
int ret;
/* check if we really have all the request data needed */
if (job->request_len < cmdlen) {
5d60: a7 c4 00 48 jle 5df0 <fc_bsg_dispatch+0x1f0>
ret = -ENOMSG;
goto fail_host_msg;
}
/* Validate the host command */
switch (bsg_request->msgcode) {
5d64: 58 20 10 00 l %r2,0(%r1)
5d68: c2 2f 80 00 00 03 clfi %r2,2147483651

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.
