Good day! Back in Comment 6 , we mentioned there was another server seeing this issue, the same distro, the only difference was that it is a zVM guest. The issue was still happening on it (sosreport causing the host to crash) After updating all available packages and being on the latest kernel, the issue was still happening. It wasn't until the NFS was removed (completely uninstalled) that a sosreport was able to complete. This means that this issue is not resolved, rather we have a workaround.

For reference the the CONFIG_DMA_DEFAULT_DMA setting is relevant to s390 only
since upstream commit c76c067e488c ("s390/pci: Use dma-iommu layer").
This commit also includes the following hunk to default to
CONFIG_DEFAULT_DMA_LAZY on s390x. Though I guess this wouldn't overwrite
a pre-existing config value:

[UBUNTU 24.04] IOMMU DMA mode changed in kernel config causes massive

[Bug 2071471] [NEW] [UBUNTU 24.04] IOMMU DMA mode changed in kernel config causes massive throughput degradation for PCI-related network workloads
Public bug reported: Symptom: Comparing Ubuntu 24.04 (kernelversion: 6.8.0-31-generic) against Ubuntu 22.04, all of our PCI-related network measurements on LPAR show massive throughput degradations (up to -72%). This shows for almost all workloads and numbers of connections, detereorating with the number of connections increasing. Especially drastic is the drop for a high number of parallel connections (50 and 250) and for small and medium-size transactional workloads. However, also for streaming-type workloads the degradation is clearly visible (up to 48% degradation). Problem: With kernel config setting CONFIG_IOMMU_DEFAULT_DMA_STRICT=y, IOMMU DMA mode changed from lazy to strict, causing these massive degradations. Behavior can also be changed with a kernel commandline parameter (iommu.strict) for easy verification. The issue is known and was quickly fixed upstream in December 2023, after being present for little less than two weeks. Upstream fix: https://github.com/torvalds/linux/commit/b2b97a62f055dd638f7f02087331a8380d8f139a Repro: rr1c-200x1000-250 with rr1c-200x1000-250.xml: 0) Install uperf on both systems, client and server. 1) Start uperf at server: uperf -s 2) Start uperf at client: uperf -vai 5 -m uperf-profile.xml 3) Switch from strict to lazy mode using kernel commandline parameter iommu.strict=0. 4) Repeat steps 1) and 2). Example: For the following example, we chose the workload named above (rr1c-200x1000-250): iommu.strict=1 (strict): 233464.914 TPS iommu.strict=0 (lazy): 835123.193 TPS ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Skipper Bug Screeners (skipper-screen-team) Status: New ** Tags: architecture-s39064 bugnameltc-207082 severity-high targetmilestone-inin--- ** Tags added: architecture-s39064 bugnameltc-207082 severity-high targetmilestone-inin--- ** Changed in: ubuntu Assignee: (unassigned) => Skipper Bug Screeners (skipper-screen-team) ** Package changed: ubuntu => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2071471 Title: [UBUNTU 24.04] IOMMU DMA mode changed in kernel config causes massive throughput degradation for PCI-related network workloads To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2071471/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

At L1 level, if we set DPDES=1 in the GSB for L2, the guest never receives the doorbell and also it is never cleared from the GSB. We are discussing this behaviour with phyp team.

We used P10 2S4U system for this experiment. Workloads: DT7 and PGBENCH in details: DT7 is an open source benchmark application emulating an online stock trading system. DT7 consist of 3 components 1) Jmeter 2) WAS (WebSphere Application Server) 3) DB2 DayTrader benchmark/application will be installed/deployed on WAS and this used DB2 as a backbone database. Jmeter generate the request and interact with the WAS. which would be kind of middle ware. PGBENCH : pgbench is a simple program for running benchmark tests on PostgreSQL. It runs the same sequence of SQL commands over and over, possibly in multiple concurrent database sessions, and then calculates the average transaction rate (transactions per second).

[Bug 2065579] Re: [UBUNTU 22.04] OS guest boot issues on 9p filesystem
--- Comment From d.herrendoer...@de.ibm.com 2024-05-13 06:57 EDT--- This Bug is the result of the fix to: CVE-2023-2861: Prohibit opening any special file directly on host I also opened a Bug in the qemu bugtracker https://gitlab.com/qemu-project/qemu/-/issues/2337 The containers fail because syslog cannot open its unix domain socket on the filesystem. We tracked the change that provokes this error to a CVE change in qemu that forbids opening of special files to prevent exposing data from the host. Special files should be handled by the guest os. Unix domain socket files are also special files, and they are handled by the guest OS in their entirety, and the 9p server in qemu assigns them individual inodes so they are safe to open. But they must be opened so their fd can be passed to the appropriate connect() or bind() function so the OS can use them. Socket files don't have a traditional read or write functionality, they are mere representatives for a local address. There is no convention for where domain socket files should go, so there is no easy fix by just creating a tmpfs somewhere. We also see other workloads and services failing for not being able to open their local socket files. The analysis of CVE-2023-2861 in detail reveals - opening of device files through the 9p server directly grants access to read/write functions of those device files. Also device files can be created in-place anywhere. - opening of FIFOs is somewhat unsafe as long as there are possible collisions that could expose host data using read/write. - opening of sockets is safe because the 9p server protects the revealed inode and provides no way to connect the file to a socket. ** CVE added: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2023-2861 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065579 Title: [UBUNTU 22.04] OS guest boot issues on 9p filesystem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2065579/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

--- Comment From wint...@de.ibm.com 2024-05-13 05:20 EDT--- Hi Phoenyx, I'm glad to hear that you were able to fix your issue. I have to admit I don't get the full picture of your analysis: The firewall gateways you mention, where are they? Inside KVM guests attached to your OSA card? Or external to IBM Z? The pinging device where is that? External connected via a physical switch? What exactly was the unexptected bahaviour of the OSA cards? In case you want us to investigate further, I would propose to try and recreate the issue and reduce it to the minimum failing scenario (just 2 endpoints; can we ommit VLAN, bridge, firewall, .. ? The less the better) And then describe exactly what the expected behaviour is, what the unexpected behaviour is and how to reproduce it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060939 Title: s390x OSA bridging causes network issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2060939/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

--- Comment From wint...@de.ibm.com 2024-05-13 05:09 EDT--- More information from phoenyx: "Hi Sandy, We?ve managed to find what was causing the behaviour of packets being received on the source interface to occur; however, we do still have a concern that the behaviour was only present on the OSA card. We had a device on the network that was attempting to ping the firewall gateways on each VLAN ? Which were configured to drop ICMP packets. This was causing the network to have a solid number of broadcast packets being sent out on each VLAN (2 per second, per VLAN). The firewalls have been reconfigured to accept ICMP traffic, and now that the broadcast packets are not being sent out, the OSA is working exactly as expected. However, the OSA cards were the only ones to display issues while this was occurring, all other NICs were functioning despite this network traffic (x86, RoCE, etc)? And we are not sure why only the OSA was displaying that behaviour. Would you happen to have any insights on this at all?

--- Comment From david_pa...@uk.ibm.com 2024-04-24 02:47 EDT--- Hi, We have had a reply from the AIX support team (see below) explaining the RENEW requests. Do you have any further questions for the AIX support team or can we supply any further diagnostic information to progress this issue ? Regarding the comment/question about RENEW reqs from Linux: RENEW is done when half the lease period has elapsed without any state operation going on. Here, the Linux server's lease is 90 seconds. From an NFS perspective, there is nothing strange or remarkable about the pattern of RENEW reqs sent in the good & bad cases. If there is a specific question about renews in the latest captures let us know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2042363 Title: AIX 7.3 NFS client frequently returns an EIO error to an application when reading or writing to a file that has been locked with fcntl() on a Ubuntu 20.04 NFSV4 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2042363/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

--- Comment From jldo...@us.ibm.com 2024-04-19 13:51 EDT--- It was decided internally that the Novalink team will be taking a patched socat .deb and placing it within their own repo to provide the correct behavior in their customer environments. Thank you to everyone that spent time on this bug. We are awaiting confirmation from the Novalink team that this method of providing the correct behavior is working successfully.

[Bug 2062556] [NEW] [Ubuntu-24.04] Hugepage memory is not getting released even after destroying the guest!
Public bug reported:
---Problem Description---
Hugepages memory is not getting released even after destroying the guest
Machine Type = P10 Denali LPAR
---uname output---
Linux ubuntu2404lp3 6.8.0-22-generic #22-Ubuntu SMP Thu Apr 4 22:47:57 UTC
2024 ppc64le ppc64le ppc64le GNU/Linux
---Steps to Reproduce---
1. Create a guest which is backed by hugepages.
2. Destroy the guest
3. execute "free -h" or "cat /proc/meminfo" to see that Hugepage memory is
still getting held.

This is an issue created by commit 1b151e2435fc ("block: Remove special-casing
of compound pages") that moved the direct-io hugetlb handling from compound
pages to folios.
Following commit has been proposed and merged into 6.9-rc1 which fixes this
issue.
38b43539d64b2fa020b3b9a752a986769f87f7a6("block: Fix page refcounts for
unaligned buffers in __bio_release_pages()")
So the same needs to be backported to the Ubuntu24.04 kernel as well.

--- Comment From david_pa...@uk.ibm.com 2024-04-18 11:00 EDT--- Hi, Thanks for looking at the logs. I agree that both syslogs (AIX 7.2 and 7.3) contain multiple "TCP recvfrom got EAGAIN" entries. To clarify the information in the attachments, I have updated the comment for the attachments of the syslog for the non-working AIX 7.3 pair (amaliada and adamsongrunter. The syslog is in two parts because the Bugzilla file uploader couldn't handle such a large file. It is NOT mixed with the AIX 7.2 syslog. The syslog for the working pair AIX 7.2 (adia and amberjack) was smaller, so it is a single file attachment. I will ask the IBM AIX support team about the NFS Client lease renewal in both AIX 7.2 and 7.3. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2042363 Title: AIX 7.3 NFS client frequently returns an EIO error to an application when reading or writing to a file that has been locked with fcntl() on a Ubuntu 20.04 NFSV4 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2042363/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I don?t really understand the setup. Why do have 30 bridges on top of 30 VLAN interfaces all connected to the same OSA interface? Why not 1 bridge with 30 vlan-bridgeports ? I am wondering whether this could be related to the infamous arp flux issue. Maybe you want to try setting net.ipv4.conf.all.arp_ignore=1 net.ipv4.conf.all.arp_announce=2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060939 Title: s390x OSA bridging causes network issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2060939/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
