[merged mm-hotfixes-stable] mm-migrate_devicec-copy-pte-dirty-bit-to-page.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/migrate_device.c: copy pte dirty bit to page has been removed from the -mm tree. Its filename was mm-migrate_devicec-copy-pte-dirty-bit-to-page.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Alistair Popple <apopple(a)nvidia.com> Subject: mm/migrate_device.c: copy pte dirty bit to page Date: Fri, 2 Sep 2022 10:35:53 +1000 migrate_vma_setup() has a fast path in migrate_vma_collect_pmd() that installs migration entries directly if it can lock the migrating page. When removing a dirty pte the dirty bit is supposed to be carried over to the underlying page to prevent it being lost. Currently migrate_vma_*() can only be used for private anonymous mappings. That means loss of the dirty bit usually doesn't result in data loss because these pages are typically not file-backed. However pages may be backed by swap storage which can result in data loss if an attempt is made to migrate a dirty page that doesn't yet have the PageDirty flag set. In this case migration will fail due to unexpected references but the dirty pte bit will be lost. If the page is subsequently reclaimed data won't be written back to swap storage as it is considered uptodate, resulting in data loss if the page is subsequently accessed. Prevent this by copying the dirty bit to the page when removing the pte to match what try_to_migrate_one() does.

[merged mm-hotfixes-stable] mm-page_alloc-fix-race-condition-between-build_all_zonelists-and-page-allocation.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/page_alloc: fix race condition between build_all_zonelists and page allocation has been removed from the -mm tree. Its filename was mm-page_alloc-fix-race-condition-between-build_all_zonelists-and-page-allocation.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Mel Gorman <mgorman(a)techsingularity.net> Subject: mm/page_alloc: fix race condition between build_all_zonelists and page allocation Date: Wed, 24 Aug 2022 12:14:50 +0100 Patrick Daly reported the following problem; NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - before offline operation [0] - ZONE_MOVABLE [1] - ZONE_NORMAL [2] - NULL For a GFP_KERNEL allocation, alloc_pages_slowpath() will save the offset of ZONE_NORMAL in ac->preferred_zoneref. If a concurrent memory_offline operation removes the last page from ZONE_MOVABLE, build_all_zonelists() & build_zonerefs_node() will update node_zonelists as shown below. Only populated zones are added. NODE_DATA(nid)->node_zonelists[ZONELIST_FALLBACK] - after offline operation [0] - ZONE_NORMAL [1] - NULL [2] - NULL The race is simple -- page allocation could be in progress when a memory hot-remove operation triggers a zonelist rebuild that removes zones. The allocation request will still have a valid ac->preferred_zoneref that is now pointing to NULL and triggers an OOM kill. This problem probably always existed but may be slightly easier to trigger due to 6aa303defb74 ("mm, vmscan: only allocate and reclaim from zones with pages managed by the buddy allocator") which distinguishes between zones that are completely unpopulated versus zones that have valid pages not managed by the buddy allocator (e.g. reserved, memblock, ballooning etc). Memory hotplug had multiple stages with timing considerations around managed/present page updates, the zonelist rebuild and the zone span updates. As David Hildenbrand puts it memory offlining adjusts managed+present pages of the zone essentially in one go. If after the adjustments, the zone is no longer populated (present==0), we rebuild the zone lists. Once that's done, we try shrinking the zone (start+spanned pages) -- which results in zone_start_pfn == 0 if there are no more pages. That happens *after* rebuilding the zonelists via remove_pfn_range_from_zone(). The only requirement to fix the race is that a page allocation request identifies when a zonelist rebuild has happened since the allocation request started and no page has yet been allocated. Use a seqlock_t to track zonelist updates with a lockless read-side of the zonelist and protecting the rebuild and update of the counter with a spinlock.

[v5.19.y PATCH 0/3] Backport the io_uring/LSM CMD passthrough controls

by Paul Moore

The stable patch merging tools failed to automatically merge the io_uring/LSM CMD passthrough controls into the stable v5.19.y branch, so I'm doing the backport manually and submitting them directly to stable for the next v5.19.y release. The backport is necessary due to the reorg/decomposition of the io_uring code in io_uring/ during the v5.19->v6.0 merge window. Other than the differences in the filenames under io_uring, the code changes are pretty much the same. I've done some basic sanity testing this afternoon with these patches and everything looks good to me. If you would prefer to pull these directly from a git tree instead of email, they are available via the LSM tree on the stable-5.19 branch, using the lsm-pr-20220906 tag. git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm.git lsm-pr-20220906 --- Paul Moore (3): lsm,io_uring: add LSM hooks for the new uring_cmd file op selinux: implement the security_uring_cmd() LSM hook Smack: Provide read control for io_uring_cmd include/linux/lsm_hook_defs.h | 1 + include/linux/lsm_hooks.h | 3 +++ include/linux/security.h | 5 +++++ io_uring/io_uring.c | 4 ++++ security/security.c | 4 ++++ security/selinux/hooks.c | 24 ++++++++++++++++++++++ security/selinux/include/classmap.h | 2 +- security/smack/smack_lsm.c | 32 +++++++++++++++++++++++++++++ 8 files changed, 74 insertions(+), 1 deletion(-)

[PATCH v2] iio: light: tsl2583: Fix module unloading

by Shreeya Patel

tsl2583 uses devm_iio_device_register() function and calling iio_device_unregister() in remove breaks the module unloading. Fix this by using iio_device_register() instead of devm_iio_device_register() function in probe.
