[PATCH] Revert "cxl/port: Enable the HDM decoder capability for switch ports"

by Dan Williams

commit eb0764b822b9 ("cxl/port: Enable the HDM decoder capability for switch ports") ...was added on the observation of CXL memory not being accessible after setting up a region on a "cold-plugged" device. A "cold-plugged" CXL device is one that was not present at boot, so platform-firmware/BIOS has no chance to set it up. While it is true that the debug found the enable bit clear in the host-bridge's instance of the global control register (CXL 3.0 8.2.4.19.2 CXL HDM Decoder Global Control Register), that bit is described as: "This bit is only applicable to CXL.mem devices and shall return 0 on CXL Host Bridges and Upstream Switch Ports." So it is meant to be zero, and further testing confirmed that this "fix" had no effect on the failure. Revert it, and be more vigilant about proposed fixes in the future. Since the original copied stable@, flag this revert for stable@ as well.

One of them is TCP_INQ cmsg support introduced in commit 2c9e77659a0c ("mptcp: add TCP_INQ cmsg support"). It is possible to look for "mptcp_ioctl" in kallsyms because it was needed to introduce the mentioned feature. We can skip these tests and not set TCPINQ option if the feature is not supported.

[mst@redhat.com: [PATCH v2] Revert "virtio-blk: support completion batching for the IRQ path"]

by Michael S. Tsirkin

----- Forwarded message from "Michael S. Tsirkin" <mst(a)redhat.com> ----- From: "Michael S. Tsirkin" <mst(a)redhat.com> Date: Fri, 9 Jun 2023 03:27:28 -0400 To: linux-kernel(a)vger.kernel.org Cc: kernel test robot <lkp(a)intel.com>, Suwan Kim <suwan.kim027(a)gmail.com>, "Roberts, Martin" <martin.roberts(a)intel.com>, Jason Wang <jasowang(a)redhat.com>, Paolo Bonzini <pbonzini(a)redhat.com>, Stefan Hajnoczi <stefanha(a)redhat.com>, Xuan Zhuo <xuanzhuo(a)linux.alibaba.com>, Jens Axboe <axboe(a)kernel.dk>, virtualization(a)lists.linux-foundation.org, linux-block(a)vger.kernel.org Subject: [PATCH v2] Revert "virtio-blk: support completion batching for the IRQ path" Message-ID: <336455b4f630f329380a8f53ee8cad3868764d5c.1686295549.git.mst(a)redhat.com> This reverts commit 07b679f70d73483930e8d3c293942416d9cd5c13. This change appears to have broken things... We now see applications hanging during disk accesses. e.g. multi-port virtio-blk device running in h/w (FPGA) Host running a simple 'fio' test. [global] thread=1 direct=1 ioengine=libaio norandommap=1 group_reporting=1 bs=4K rw=read iodepth=128 runtime=1 numjobs=4 time_based [job0] filename=/dev/vda [job1] filename=/dev/vdb [job2] filename=/dev/vdc ... [job15] filename=/dev/vdp i.e. 16 disks; 4 queues per disk; simple burst of 4KB reads This is repeatedly run in a loop. After a few, normally <10 seconds, fio hangs. With 64 queues (16 disks), failure occurs within a few seconds; with 8 queues (2 disks) it may take ~hour before hanging. Last message: fio-3.19 Starting 8 threads Jobs: 1 (f=1): [_(7),R(1)][68.3%][eta 03h:11m:06s] I think this means at the end of the run 1 queue was left incomplete. 'diskstats' (run while fio is hung) shows no outstanding transactions. e.g. $ cat /proc/diskstats ... 252 0 vda 1843140071 0 14745120568 712568645 0 0 0 0 0 3117947 712568645 0 0 0 0 0 0 252 16 vdb 1816291511 0 14530332088 704905623 0 0 0 0 0 3117711 704905623 0 0 0 0 0 0 ...

[PATCH net 0/6] mptcp: fixes for 6.4

by Matthieu Baerts

Patch 1 correctly handles disconnect() failures that can happen in some specific cases: now the socket state is set as unconnected as expected. That fixes an issue introduced in v6.2. Patch 2 fixes a divide by zero bug in mptcp_recvmsg() with a fix similar to a recent one from Eric Dumazet for TCP introducing sk_wait_pending flag. It should address an issue present in MPTCP from almost the beginning, from v5.9. Patch 3 fixes a possible list corruption on passive MPJ even if the race seems very unlikely, better be safe than sorry. The possible issue is present from v5.17. Patch 4 consolidates fallback and non fallback state machines to avoid leaking some MPTCP sockets. The fix is likely needed for versions from v5.11. Patch 5 drops code that is no longer used after the introduction of patch 4/6. This is not really a fix but this patch can probably land in the -net tree as well not to leave unused code. Patch 6 ensures listeners are unhashed before updating their sk status to avoid possible deadlocks when diag info are going to be retrieved with a lock. Even if it should not be visible with the way we are currently getting diag info, the issue is present from v5.17.

[PATCH] drm/amd/display: perform a bounds check before filling dirty rectangles

by Hamza Mahfooz

Currently, it is possible for us to access memory that we shouldn't. Since, we acquire (possibly dangling) pointers to dirty rectangles before doing a bounds check to make sure we can actually accommodate the number of dirty rectangles userspace has requested to fill. This issue is especially evident if a compositor requests both MPO and damage clips at the same time, in which case I have observed a soft-hang. So, to avoid this issue, perform the bounds check before filling a single dirty rectangle and WARN() about it, if it is ever attempted in fill_dc_dirty_rect().
