I updated the bug with the below comment:
I'm not sure if this ib_srp-backport patch is related, but it worth to take a
look.
IB/srp: Improve an error path
Avoid that the following message is printed if login fails: scsi host0: ib_srp:
Sending CM DREQ failed

Ok, so it’s safe to say we are missing some bug fixes after kernel.org 4.8.
+Amir, to help isolate and validate.

The upstream test was for Bug 2631, SRP Reject Issue. The Base OS was SL 7.3
(not SL 7.2) w/ OFED 4.8-rc4 and the ib_srp_backport_4_11. That combination
worked properly.

Subject: RE: [ewg] [GIT PULL compat-rdma] qib for OFED 4.8
I tested SL 7.2 with OFED 4.8-rc4. Scanning SRP targets yielded the following
response:
Ok, so this is a kernel.org 4.8 base SRP driver backported to 3.10.
Can someone tell me if the same problem exists with upstream SRP driver in
kernel 4.8?
This will tell me if it is an OFED 4.8 backport issue or if it is a kernel
4.8 SRP driver issue.
ib_srp: Sending CM DREQ failed and the SRP targets were never scanned. (See Bug
2632. http://bugs.openfabrics.org/show_bug.cgi?id=2632)
I attempted to use Bart Van Assche’s ib_srp_backport driver on top of SL 7.2
and OFED 4.8-rc4 according to his instructions. The ib_srp_backport driver
failed to compile (see attached text file). The ib_srp_backport driver will not
compile with OFED 4.8-rc4 installed. I was able to uninstall OFED 4.8-rc4, then
compile the driver. However, when OFED 4.8-rc4 was reinstalled, the
ib_srp_backport driver was not compatible.
Ok, I think I understand.
This is the upstream test that you said passed? A SL
7.2+infiniband+ib_srp_backport_from_4.11?
Correct?

That’s all of the testing , so far.

Sorry, I am still trying to understand what is working and what is needed to
fix this for OFED 4.8.
When you said you tested the upstream kernel, was it SL 7.2 kernel plus the
backports from Bart’s 4.11 drop? Do you need the 4.11 kernel base driver set
for SRP to work properly?
