...

22. Bug 2640 - openibd fail to start when system is coming up:

Hi Vlad and All,

During soft-forge testing of the package containing the fixes, we hit a 
different issue which I believe could affect all vendors

The problem is when drivers are part of the initramfs/initrd of the distro as 
they come inbox.
In our case qed/qede are inbox, but qedr is not. Meaning that qed/qede are in 
initrd and loaded automatically with older version
than the one installed by OFED. Then when qedr is probed there is a mismatch, 
as the OFED qedr version is newer and incompatible.
If the qedr was inbox as well, we probably wouldn't have even noticed that OFED 
drivers aren't loaded.
(they will be loaded only after an rmmod of all qed drivers and modprobe )

In our Out-of-box installation scripts, we update the initramfs with the newly 
compiled drivers. I'd expect to see the same at the end of an OFED build
( dracut -f / update initrd, mkinitrd etc... for example )

We could just document this for the user to rebuild the ramfs after OFED 
installation.
I'm not sure how this didn't come up until now, I've looked a bit on our setups 
and noticed that a lot have omit-drivers in the lsinitrd or older drivers that
We're installed etc... this is easy to miss. In addition, the only reason we 
did hit this is because the inbox / ofed drivers are mismatched...

Thanks,
Michal

Hello Michal,

Great progress, kudos to the team for a quick resolution. I concur, let's test
before we roll RC3.

Vlad, please pull these fixes into new daily build so Brendan can test.

Arlin


Hi Arlin,

We've been working with Brendan on this and were able to reproduce on
our setups fix, and test locally.
There are three commits (2 fix the issue and 1 fix was exposed that
our data collection had an issue)
2 out of the 3 fixes have already been upstream in official linux revisions.
one of the fixes can't go through next as is as the code varies quite a bit.

Brendan will only be able to fully verify the fix Monday / Tuesday.

The commits that need to be pulled are in my github:

https://github.com/mkalderon/ofed-compat-
rdma/commit/f20134d8f4736c6ce30975bb920cf64c2ec4248d
https://github.com/mkalderon/ofed-compat-
rdma/commit/171235eb14bf2a7bccd28650470c44807ea644e4
https://github.com/mkalderon/ofed-compat-
rdma/commit/4c5949ba5d075d814e30dc18bd4cdd71b45c972f

I would prefer Brendan gave this a test before rc-3. But I understand
we're on a tight timeframe.

thanks,
Michal

Quick update on RC3..

Broadcom has all critical bugs fixed and included in a new daily build.
Thanks!

20180228-1121.tgz


Our final blocking item is a critical "perftest hang" issue on a
Cavium
QL45412 RoCE adapter.

Bug 2674<http://bugs.openfabrics.org/bugzilla/show_bug.cgi?id=2674>
"Unable to complete RDMA applications (perftest)".

Michal, can we please get an ETA for the fix or a "won't fix"
disposition so we can push forward with RC3?

Regards,

Arlin
