[PATCH v5] mm: mmap: map MAP_STACK to VM_NOHUGEPAGE only if THP is enabled

by Ignacio Moreno Gonzalez via B4 Relay

From: Ignacio Moreno Gonzalez <Ignacio.MorenoGonzalez(a)kuka.com> commit c4608d1bf7c6 ("mm: mmap: map MAP_STACK to VM_NOHUGEPAGE") maps the mmap option MAP_STACK to VM_NOHUGEPAGE. This is also done if CONFIG_TRANSPARENT_HUGEPAGE is not defined. But in that case, the VM_NOHUGEPAGE does not make sense. I discovered this issue when trying to use the tool CRIU to checkpoint and restore a container. Our running kernel is compiled without CONFIG_TRANSPARENT_HUGEPAGE. CRIU parses the output of /proc/<pid>/smaps and saves the "nh" flag. When trying to restore the container, CRIU fails to restore the "nh" mappings, since madvise() MADV_NOHUGEPAGE always returns an error because CONFIG_TRANSPARENT_HUGEPAGE is not defined.

[PATCH v1] drm/bridge: cdns-dsi: Replace deprecated UNIVERSAL_DEV_PM_OPS()

by Vitor Soares

From: Vitor Soares <vitor.soares(a)toradex.com> The deprecated UNIVERSAL_DEV_PM_OPS() macro uses the provided callbacks for both runtime PM and system sleep. This causes the DSI clocks to be disabled twice: once during runtime suspend and again during system suspend, resulting in a WARN message from the clock framework when attempting to disable already-disabled clocks.

net/sched: codel: Inclusion of patchset

by Tai, Gerrard

Upstream commits: 01: 5ba8b837b522d7051ef81bacf3d95383ff8edce5 ("sch_htb: make htb_qlen_notify() idempotent") 02: df008598b3a00be02a8051fde89ca0fbc416bd55 ("sch_drr: make drr_qlen_notify() idempotent") 03: 51eb3b65544c9efd6a1026889ee5fb5aa62da3bb ("sch_hfsc: make hfsc_qlen_notify() idempotent") 04: 55f9eca4bfe30a15d8656f915922e8c98b7f0728 ("sch_qfq: make qfq_qlen_notify() idempotent") 05: a7a15f39c682ac4268624da2abdb9114bdde96d5 ("sch_ets: make est_qlen_notify() idempotent") 06: 342debc12183b51773b3345ba267e9263bdfaaef ("codel: remove sch->q.qlen check before qdisc_tree_reduce_backlog()") These patches are patch 01-06 of the original patchset ([1]) authored by Cong Wang. I have omitted patches 07-11 which are selftests. This patchset addresses a UAF vulnerability. Originally, only the last commit (06) was picked to merge into the latest round of stable queues 5.15,5.10,5.4. For 6.x stable branches, that sole commit has already been merged in a previous cycle. From my understanding, this patch depends on the previous patches to work. Without patches 01-05 which make various classful qdiscs' qlen_notify() idempotent, if an fq_codel's dequeue() routine empties the fq_codel qdisc, it will be doubly deactivated - first in the parent qlen_notify and then again in the parent dequeue. For instance, in the case of parent drr, the double deactivation will either cause a fault on an invalid address, or trigger a splat if list checks are compiled into the kernel. This is also why the original unpatched code included the qlen check in the first place. After discussion with Greg, he has helped to temporarily drop the patch from the 5.x queues ([2]). My suggestion is to include patches 01-06 of the patchset, as listed above, for the 5.x queues. For the 6.x queues that have already merged patch 06, the earlier patches 01-05 should be merged too. I'm not too familiar with the stable patch process, so I may be completely mistaken here.

[PATCH v5] x86/sev: Fix making shared pages private during kdump

by Ashish Kalra

From: Ashish Kalra <ashish.kalra(a)amd.com> When the shared pages are being made private during kdump preparation there are additional checks to handle shared GHCB pages. These additional checks include handling the case of GHCB page being contained within a huge page. The check for handling the case of GHCB contained within a huge page incorrectly skips a page just below the GHCB page from being transitioned back to private during kdump preparation. This skipped page causes a 0x404 #VC exception when it is accessed later while dumping guest memory during vmcore generation via kdump. Correct the range to be checked for GHCB contained in a huge page. Also ensure that the skipped huge page containing the GHCB page is transitioned back to private by applying the correct address mask later when changing GHCBs to private at end of kdump preparation.

[PATCH v4] mm: mmap: map MAP_STACK to VM_NOHUGEPAGE only if THP is enabled

by Ignacio Moreno Gonzalez via B4 Relay

From: Ignacio Moreno Gonzalez <Ignacio.MorenoGonzalez(a)kuka.com> commit c4608d1bf7c6 ("mm: mmap: map MAP_STACK to VM_NOHUGEPAGE") maps the mmap option MAP_STACK to VM_NOHUGEPAGE. This is also done if CONFIG_TRANSPARENT_HUGETABLES is not defined. But in that case, the VM_NOHUGEPAGE does not make sense. I discovered this issue when trying to use the tool CRIU to checkpoint and restore a container. Our running kernel is compiled without CONFIG_TRANSPARENT_HUGETABLES. CRIU parses the output of /proc/<pid>/smaps and saves the "nh" flag. When trying to restore the container, CRIU fails to restore the "nh" mappings, since madvise() MADV_NOHUGEPAGE always returns an error because CONFIG_TRANSPARENT_HUGEPAGE is not defined. Fixes: c4608d1bf7c6 ("mm: mmap: map MAP_STACK to VM_NOHUGEPAGE") Cc: stable(a)vger.kernel.org Reviewed-by: Lorenzo Stoakes <lorenzo.stoakes(a)oracle.com> Reviewed-by: Yang Shi <yang(a)os.amperecomputing.com> Reviewed-by: Liam R. Howlett <Liam.Howlett(a)oracle.com> Signed-off-by: Ignacio Moreno Gonzalez <Ignacio.MorenoGonzalez(a)kuka.com> --- I discovered this issue when trying to use the tool CRIU to checkpoint and restore a container. Our running kernel is compiled without CONFIG_TRANSPARENT_HUGEPAGE. CRIU parses the output of /proc/<pid>/smaps and saves the "nh" flag. When trying to restore the container, CRIU fails to restore the "nh" mappings, since madvise() MADV_NOHUGEPAGE always returns an error because CONFIG_TRANSPARENT_HUGEPAGE is not defined. The mapping MAP_STACK -> VM_NOHUGEPAGE was introduced by commit c4608d1bf7c6 ("mm: mmap: map MAP_STACK to VM_NOHUGEPAGE") in order to fix a regression introduced by commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP boundaries"). The change introducing the regression (efa7df3e3bb5) was limited to THP kernels, but its fix (c4608d1bf7c6) is applied without checking if THP is set. The mapping MAP_STACK -> VM_NOHUGEPAGE should only be applied if THP is enabled. --- Changes in v4: - Correct typo CONFIG_TRANSPARENT_HUGETABLES -> CONFIG_TRANSPARENT_HUGEPAGE - Copy description from cover letter to commit description - Link to v3: https://lore.kernel.org/r/20250507-map-map_stack-to-vm_nohugepage-only-if-t… Changes in v3: - Exclude non-stable patch (for huge_mm.h) from this series to avoid mixing stable and non-stable patches, as suggested by Andrew. - Extend description in cover letter. - Link to v2: https://lore.kernel.org/r/20250506-map-map_stack-to-vm_nohugepage-only-if-t… Changes in v2: - [Patch 1/2] Use '#ifdef' instead of '#if defined(...)' - [Patch 1/2] Add 'Fixes: c4608d1bf7c6...' - Create [Patch 2/2] - Link to v1: https://lore.kernel.org/r/20250502-map-map_stack-to-vm_nohugepage-only-if-t… --- include/linux/mman.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/include/linux/mman.h b/include/linux/mman.h index bce214fece16b9af3791a2baaecd6063d0481938..f4c6346a8fcd29b08d43f7cd9158c3eddc3383e1 100644 --- a/include/linux/mman.h +++ b/include/linux/mman.h @@ -155,7 +155,9 @@ calc_vm_flag_bits(struct file *file, unsigned long flags) return _calc_vm_trans(flags, MAP_GROWSDOWN, VM_GROWSDOWN ) | _calc_vm_trans(flags, MAP_LOCKED, VM_LOCKED ) | _calc_vm_trans(flags, MAP_SYNC, VM_SYNC ) | +#ifdef CONFIG_TRANSPARENT_HUGEPAGE _calc_vm_trans(flags, MAP_STACK, VM_NOHUGEPAGE) | +#endif arch_calc_vm_flag_bits(file, flags); } --- base-commit: fc96b232f8e7c0a6c282f47726b2ff6a5fb341d2 change-id: 20250428-map-map_stack-to-vm_nohugepage-only-if-thp-is-enabled-ce40a1de095d Best regards, -- Ignacio Moreno Gonzalez <Ignacio.MorenoGonzalez(a)kuka.com>

[PATCH v2 1/4] mm: fix VM_UFFD_MINOR == VM_SHADOW_STACK on USERFAULTFD=y && ARM64_GCS=y

by Florent Revest

On configs with CONFIG_ARM64_GCS=y, VM_SHADOW_STACK is bit 38. On configs with CONFIG_HAVE_ARCH_USERFAULTFD_MINOR=y (selected by CONFIG_ARM64 when CONFIG_USERFAULTFD=y), VM_UFFD_MINOR is _also_ bit 38. This bit being shared by two different VMA flags could lead to all sorts of unintended behaviors. Presumably, a process could maybe call into userfaultfd in a way that disables the shadow stack vma flag. I can't think of any attack where this would help (presumably, if an attacker tries to disable shadow stacks, they are trying to hijack control flow so can't arbitrarily call into userfaultfd yet anyway) but this still feels somewhat scary.

[PATCH RESEND v3 5/5] phy: renesas: rcar-gen3-usb2: Set timing registers only once

by Claudiu

From: Claudiu Beznea <claudiu.beznea.uj(a)bp.renesas.com> phy-rcar-gen3-usb2 driver exports 4 PHYs. The timing registers are common to all PHYs. There is no need to set them every time a PHY is initialized. Set timing register only when the 1st PHY is initialized.
