This resolves a kernel BUG reported by syzbot. Since there are two flaws involved, I've made each one a separate patch. The first patch alone resolves the syzbot-reported bug, but I think both fixes should be sent to stable, so I've tagged them as such. This patch (of 2): Syzbot has reported a kernel bug in submit_bh_wbc() when writing file data to a nilfs2 file system whose metadata is corrupted. There are two flaws involved in this issue. The first flaw is that when nilfs_get_block() locates a data block using btree or direct mapping, if the disk address translation routine nilfs_dat_translate() fails with internal code -ENOENT due to DAT metadata corruption, it can be passed back to nilfs_get_block(). This causes nilfs_get_block() to misidentify an existing block as non-existent, causing both data block lookup and insertion to fail inconsistently. The second flaw is that nilfs_get_block() returns a successful status in this inconsistent state. This causes the caller __block_write_begin_int() or others to request a read even though the buffer is not mapped, resulting in a BUG_ON check for the BH_Mapped flag in submit_bh_wbc() failing. This fixes the first issue by changing the return value to code -EINVAL when a conversion using DAT fails with code -ENOENT, avoiding the conflicting condition that leads to the kernel bug described above. Here, code -EINVAL indicates that metadata corruption was detected during the block lookup, which will be properly handled as a file system error and converted to -EIO when passing through the nilfs2 bmap layer.

[PATCH v2] btrfs: validate device maj:min during open

by Anand Jain

Boris managed to create a device capable of changing its maj:min without altering its device path. Only multi-devices can be scanned. A device that gets scanned and remains in the Btrfs kernel cache might end up with an incorrect maj:min. Despite the tempfsid feature patch did not introduce this bug, it could lead to issues if the above multi-device is converted to a single device with a stale maj:min. Subsequently, attempting to mount the same device with the correct maj:min might mistake it for another device with the same fsid, potentially resulting in wrongly auto-enabling the tempfsid feature. To address this, this patch validates the device's maj:min at the time of device open and updates it if it has changed since the last scan.

[PATCH] PCI: fix link retrain status in pcie_wait_for_link_delay()

by Simon Guinot

The current code in pcie_wait_for_link_delay() handles the value returned by pcie_failed_link_retrain() as an integer, expecting 0 when the link has been successfully retrained. The issue is that pcie_failed_link_retrain() returns a boolean: "true" if the link has been successfully retrained and "false" otherwise. This leads pcie_wait_for_link_delay() to return an incorrect "active link" status when pcie_failed_link_retrain() is called. This patch fixes the check of the value returned by pcie_failed_link_retrain() in pcie_wait_for_link_delay(). Note that this bug induces abnormal timeout delays when a PCI device is unplugged (around 60 seconds per bridge / secondary bus removed).

[PATCH] powerpc: xor_vmx: Add '-mhard-float' to CFLAGS

by Nathan Chancellor

arch/powerpc/lib/xor_vmx.o is built with '-msoft-float' (from the main powerpc Makefile) and '-maltivec' (from its CFLAGS), which causes an error when building with clang after a recent change in main: error: option '-msoft-float' cannot be specified with '-maltivec' make[6]: *** [scripts/Makefile.build:243: arch/powerpc/lib/xor_vmx.o] Error 1 Explicitly add '-mhard-float' before '-maltivec' in xor_vmx.o's CFLAGS to override the previous inclusion of '-msoft-float' (as the last option wins), which matches how other areas of the kernel use '-maltivec', such as AMDGPU.

[PATCH STABLE v6.1.y] mm/migrate: set swap entry values of THP tail pages properly.

by Zi Yan

From: Zi Yan <ziy(a)nvidia.com> The tail pages in a THP can have swap entry information stored in their private field. When migrating to a new page, all tail pages of the new page need to update ->private to avoid future data corruption. This fix is stable-only, since after commit 07e09c483cbe ("mm/huge_memory: work on folio->swap instead of page->private when splitting folio"), subpages of a swapcached THP no longer requires the maintenance. Adding THPs to the swapcache was introduced in commit 38d8b4e6bdc87 ("mm, THP, swap: delay splitting THP during swap out"), where each subpage of a THP added to the swapcache had its own swapcache entry and required the ->private field to point to the correct swapcache entry. Later, when THP migration functionality was implemented in commit 616b8371539a6 ("mm: thp: enable thp migration in generic path"), it initially did not handle the subpages of swapcached THPs, failing to update their ->private fields or replace the subpage pointers in the swapcache. Subsequently, commit e71769ae5260 ("mm: enable thp migration for shmem thp") addressed the swapcache update aspect. This patch fixes the update of subpage ->private fields.

[PATCH 2/2] f2fs: truncate page cache before clearing flags when aborting atomic file

by Sunmin Jeong

In f2fs_do_write_data_page, FI_ATOMIC_FILE flag selects the target inode between the original inode and COW inode.

[PATCH 1/2] f2fs: mark inode dirty for FI_ATOMIC_COMMITTED flag

by Sunmin Jeong

In f2fs_update_inode, i_size of the atomic file isn't updated until FI_ATOMIC_COMMITTED flag is set. When committing atomic write right after the writeback of the inode, i_size of the raw inode will not be updated. It can cause the atomicity corruption due to a mismatch between old file size and new data.
