Bart and Vlad,
What is the best way to pull in 4.11 fixes into OFED 4.8?
Looks like a lot of changes between 4.8 and 4.11.

The question is, do we need everything that is in 4.11 or is there just one or
two fixes in 4.11 that would fix this specific issue rather than trying to
backport the entire 4.11 srp driver ?

I do not think this is an acceptable workaround. An SRP target could have many
hosts connected (IO nodes), not just the one that may have been abruptly
rebooted (due to a power failure or pulled power cord). Are you suggesting that
customers must reboot all of the IO nodes in their cluster attac
I tested the upstream driver from Bart VanAssche and it does not have the same
issue as the OFED-4.8-rc4 ib_srp driver. The upstream driver handles the
SRP_Reject as expected without crashing the SL 7.3 kernel. That is also
detailed in the defect.

No upstream kernel. SL 7.2 (3.10.0-327.el7.x86_64), OFED-4.8-rc4. Was unable to
build the backport ib_srp backport driver on this platform with OFED 4.8-rc4
installed. Multiple build errors. However, if I uninstall OFED-4.8-rc4, I am
able to build the upstream ib_srp RPMs on SL 7.2

I can’t say for sure. I am attempting to build the upstream ib_srp driver for
this platform, but I am running into build issues. Bart, I will send you a
separate email on that subject.

Hi Vlad,
Please pull from git://flatbed.openfabrics.org/~tomaszc/compat-rdma:for_vlad

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.

Hello Arlin and Robert,
A backported version of the 4.11 ib_srp driver that already has been
tested is available at https://github.com/bvanassche/ib_srp-backport.
That driver builds fine against kernel.org kernels, RHEL/CentOS kernels,
openSuSE and SLES kernels and also against MOFED and OFED. Has

Would this work for DDN? We could add the URL and the SRP backport readme to
the OFED release notes. I believe you had an issue when applying the backport
to SL 7.2 and OFED 4.8 RC4 but I think Bart fixed that already.
Thanks, Arlin

Hello Arlin,
Adding a URL to the OFED README is not the same as including a version of the
ib_srp-backport driver in OFED. How can OFED users know what version of the
ib_srp-backport driver has been tested in combination with which OFED version?
Thanks,
Bart.

Ok. Vlad, what would it take to get this backported version of SRP into OFED
4.8?

SRP is included already in OFED-4.8 as a part of linux-4.8 kernel and I
don't see any reason to include SRP code twice.
If some bug fixes have to be added there then there is a specific place
in compat-rdma git tree for the relevant patches.
If somebody is interested to add an additional SRP stan
