Re: [ewg] [GIT PULL compat-rdma] qib for OFED 4.8
I suggest that we limit OFED 4.8-1 to the following items: * Broadcom Drivers * Cavium Drivers * SRP fix Both the Broadcom and Cavium drivers were tested with OFED 4.8 RC1 during the IBTA Plugfest when we did the RoCE Interoperability testing. The results were very good – see the RoCE Interoperability List: https://cw.infinibandta.org/document/dl/8203 So I feel that if Bart and DDN can work on an SRP fix, we should be able to release OFED 4.8-1 GA within approximately 30 days after the release of OFED 4.8 GA. Therefore the sooner we release OFED 4.8 GA, the sooner Vlad can start integrating Broadcom and Cavium drivers into OFED so we can get daily builds and start testing. Hopefully an SRP fix will be available in the next week or so. Therefore I am supportive of releasing OFED 4.8 GA with the condition that we do a very fast turnaround on OFED 4.8-1.

I vote for documenting the problem as a known issue with documentation on any known workarounds (such as using Bart's srp_backports driver) and then work on getting an in-box fix into OFED-4.8-1. especially since we are attempting to have a quick turn-around for OFED-4.8-1 since the new content being added is limited, and thus it should not take too long to get done.

We need community input here or some direction from the co-chairs (Woody and Vlad) so we can move forward. I have no problem waiting for a fix if someone can give the EWG a timely ETA on an upstream fix. From what I can tell, the maintainer doesn't have the bandwidth and DDN doesn't have the expertise to fix so I don't see any quick resolution. There are several OFA members anxiously waiting for OFED 4.8-1 to add their new drivers and many that need to get OFED 4.8 GA done. Not sure we can wait weeks and/or months for this to get resolved.

Re: [ewg] [GIT PULL compat-rdma] qib for OFED 4.8
I know that DDN really wants to hold the release until a fix is available. I am personally OK with just documenting the known issues for now and fixing them in OFED-4.8-1 as I know there are some people that want to use what is there now and do not care about SRP.

Port the upstream fixes that you need back to the 4.8 version that is in OFED and send a patch to Vlad. If the upstream maintainer is not interested in fixing it, then we need someone from the OFED community to take ownership of the version of SRP that is in OFED, do the testing and send in patches if there are bugs that need fixing. If the bug is broken upstream, then work with the upstream maintainer to get it fixed upstream and then backport it to OFED.

Re: [ewg] [GIT PULL compat-rdma] qib for OFED 4.8
Hi Marty, First, the issue should be fixed in the latest upstream kernel (4.12-rc7). Once the fix is submitted upstream it can be integrated into OFED-4.8.

Re: [ewg] [GIT PULL compat-rdma] qib for OFED 4.8
It seems like we now have a way to apply the latest SRP upstream fixes to OFED 4.8, tested with RH 7.2 and RH7.3. However, we still have 2 critical bugs (1 new one) on RH 7.2 even after the upstream fixes are applied. RH 7.3+OFED4.8+srp_backport seems to be fine. http://bugs.openfabrics.org/show_bug.cgi?id=2632 http://bugs.openfabrics.org/show_bug.cgi?id=2634 How does DDN want to proceed? Is it acceptable to apply upstream version/fixes to OFED 4.8 as follow, document in release notes? Can you tell us if the remaining bugs are related to OFED 4.8 or if RH7.2+infiniband+srp_backport has the same issues? The ib_srp-backport procedure is as follows: 1. Install the OS (RHEL, SLES, ...). 2. Install OFED. 3. Install the ib_srp-backport driver: git clone https://github.com/bvanassche/ib_srp-backport cd ib_srp-backport make rpm sudo rpm -U $PWD/rpmbuilddir/RPMS/*/*.rpm Thanks, Arlin > 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 standalone package then > please send me the relevant patches for compat-rdma/ofed_scripts and build > git trees. > > Regards, > Vladimir > > > On 06/20/2017 09:01 PM, Davis, Arlin R wrote: > > Ok.

Re: [ewg] [GIT PULL compat-rdma] qib for 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 standalone package then please send me the relevant patches for compat-rdma/ofed_scripts and build git trees.

The backported ib_srp driver has a defect where it is not handling an SRP_Reject properly leaving a null pointer for the blk_mq driver. Normally, this would just be a note in the log and the srp_daemon could be setup to attempt a reconnect after 30 seconds. But, that is no longer possible with the current defect. The host would crash and reboot every time a connection is attempted. -Marty Schlining From: Woodruff, Robert J [mailto:robert.j.woodr...@intel.com] Sent: Friday, June 16, 2017 12:18 PM To: Davis, Arlin R <arlin.r.da...@intel.com<mailto:arlin.r.da...@intel.com>>; RSD@SFI <rsda...@soft-forge.com<mailto:rsda...@soft-forge.com>>; 'Vladimir Sokolovsky' <v...@dev.mellanox.co.il<mailto:v...@dev.mellanox.co.il>> Cc: bart.vanass...@gmail.com<mailto:bart.vanass...@gmail.com>; ewg@lists.openfabrics.org<mailto:ewg@lists.openfabrics.org>; Marty Schlining <mschlin...@ddn.com<mailto:mschlin...@ddn.com>> Subject: RE: [ewg] [GIT PULL compat-rdma] qib for OFED 4.8 When I read the bug, it looks like the work around is to also reboot the target whenever the host is rebooted.
