I just checked the SUSE bug and it lists the following three relevant commits, whilst the last one seems the relevant one: d176b1f62f24 "ext4: handle error of ext4_setup_system_zone() on remount" bf9a379d0980 "ext4: don't allow overlapping system zones" ce9f24cccdc0 "ext4: check journal inode extents more carefully" ce9f24cccdc0 was indeed included in 5.9-rc2, and backported to v5.7.18: 3b654d118548ef2bb212dca361a5d1d19707822d ext4: check journal inode extents more carefully v5.8.4: cfa678021a1bb6b5ce4aa45c865f2d3167646f89 ext4: check journal inode extents more carefully v5.9-rc2: ce9f24cccdc019229b70a5c15e2b09ad9c0ab5d1 ext4: check journal inode extents more carefully Then though it has Fixes: 0a944e8a6c66 ("ext4: don't perform block validity checks on the journal inode") and 0a944e8a6c66 itself was backported to some of the stable series as well, I found: v3.16.85: 71bfaf9e30125ec5b408fd328e412abf3b23214d ext4: don't perform block validity checks on the journal inode v4.14.178: fc3293a80acc469fbabc91bfbf2e65dc84377dc7 ext4: don't perform block validity checks on the journal inode v4.19.73: 97fbf573460e56ddf172614f70cdfa2af03b20ea ext4: don't perform block validity checks on the journal inode v4.4.221: 571fa68cacdf5fa70a6fdb71bda051f822d3cfb6 ext4: don't perform block validity checks on the journal inode v4.9.221: 2130aae807893cff163404bf6f6f6a4906dd14a1 ext4: don't perform block validity checks on the journal inode v5.2-rc2: 0a944e8a6c66ca04c7afbaa17e22bf208a8b37f0 ext4: don't perform block validity checks on the journal inode So in the current still supported stable series, in 4.9.221, 4.14.178 and 4.19.73. I just tried the reproducer from https://bugzilla.suse.com/show_bug.cgi?id=1173485 on a system with 4.19.177 which so has not yet the 0a944e8a6c66 ("ext4: don't perform block validity checks on the journal inode") fix backported and it indeed causes: [ 224.003978] ------------[ cut here ]------------ [ 224.005052] kernel BUG at fs/ext4/extents_status.c:762!

Is this correct? I only quickly skimmed over the report, but this seems to be the case. Regards, Salvatore

[PATCH] drm/i915/ilk-glk: Fix link training on links with LTTPRs

by Imre Deak

The spec requires to use at least 3.2ms for the AUX timeout period if there are LT-tunable PHY Repeaters on the link (2.11.2). An upcoming spec update makes this more specific, by requiring a 3.2ms minimum timeout period for the LTTPR detection reading the 0xF0000-0xF0007 range (3.6.5.1). Accordingly disable LTTPR detection until GLK, where the maximum timeout we can set is only 1.6ms. Link training in the non-transparent mode is known to fail at least on some SKL systems with a WD19 dock on the link, which exposes an LTTPR (see the References below). While this could have different reasons besides the too short AUX timeout used, not detecting LTTPRs (and so not using the non-transparent LT mode) fixes link training on these systems. While at it add a code comment about the platform specific maximum timeout values.

But this operation is performed way too late, because : - The owning translation regime of the SPE buffer is transferred to EL2. (MDCR_EL2_E2PB == 0) - The guest Stage1 is loaded. Thus the flush could use the host EL1 virtual address, but use the EL2 translations instead of host EL1, for writing out any cached data. Fix this by moving the SPE buffer handling early enough. The restore path is doing the right thing.

[PATCH 1/2] perf/x86/intel: Fix a crash caused by zero PEBS status

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> A repeatable crash can be triggered by the perf_fuzzer on some Haswell system. https://lore.kernel.org/lkml/7170d3b-c17f-1ded-52aa-cc6d9ae999f4@maine.edu/ For some old CPUs (HSW and earlier), the PEBS status in a PEBS record may be mistakenly set to 0. To minimize the impact of the defect, the commit was introduced to try to avoid dropping the PEBS record for some cases. It adds a check in the intel_pmu_drain_pebs_nhm(), and updates the local pebs_status accordingly. However, it doesn't correct the PEBS status in the PEBS record, which may trigger the crash, especially for the large PEBS. It's possible that all the PEBS records in a large PEBS have the PEBS status 0. If so, the first get_next_pebs_record_by_bit() in the __intel_pmu_pebs_event() returns NULL. The at = NULL. Since it's a large PEBS, the 'count' parameter must > 1. The second get_next_pebs_record_by_bit() will crash. Besides the local pebs_status, correct the PEBS status in the PEBS record as well.

[PATCH] iommu/amd: Fix iommu remap panic while amd_iommu is set to disable

by Huang Rui

While amd_iommu is set to disable in cmd line, it will free the iommu resources. Then the pages of rlookup table is freed as well. If that, we have to check rlookup table in irq_remapping_select(), otherwise, it will trigger a kernel panic below.
