In the Linux kernel, the following vulnerability has been resolved: btrfs: do proper folio cleanup when cow_file_range() failed [BUG] When testing with COW fixup marked as BUG_ON() (this is involved with the new pin_user_pages*() change, which should not result new out-of-band dirty pages), I hit a crash triggered by the BUG_ON() from hitting COW fixup path. This BUG_ON() happens just after a failed btrfs_run_delalloc_range(): BTRFS error (device dm-2): failed to run delalloc range, root 348 ino 405 folio 65536 submit_bitmap 6-15 start 90112 len 106496: -28 ------------[ cut here ]------------ kernel BUG at fs/btrfs/extent_io.c:1444!

Although the -ENOSPC is already a bug related to our space reservation code, let's just focus on the error handling. For example, we have the following dirty range [0, 64K) of an inode, with 4K sector size and 4K page size: 0 16K 32K 48K 64K |///////////////////////////////////////| |#######################################| Where |///| means page are still dirty, and |###| means the extent io tree has EXTENT_DELALLOC flag. - Enter extent_writepage() for page 0 - Enter btrfs_run_delalloc_range() for range [0, 64K) - Enter cow_file_range() for range [0, 64K) - Function btrfs_reserve_extent() only reserved one 16K extent So we created extent map and ordered extent for range [0, 16K) 0 16K 32K 48K 64K |////////|//////////////////////////////| |<- OE ->|##############################| And range [0, 16K) has its delalloc flag cleared. But since we haven't yet submit any bio, involved 4 pages are still dirty. - Function btrfs_reserve_extent() returns with -ENOSPC Now we have to run error cleanup, which will clear all EXTENT_DELALLOC* flags and clear the dirty flags for the remaining ranges: 0 16K 32K 48K 64K |////////| | | | | Note that range [0, 16K) still has its pages dirty. - Some time later, writeback is triggered again for the range [0, 16K) since the page range still has dirty flags. - btrfs_run_delalloc_range() will do nothing because there is no EXTENT_DELALLOC flag. - extent_writepage_io() finds page 0 has no ordered flag Which falls into the COW fixup path, triggering the BUG_ON(). Unfortunately this error handling bug dates back to the introduction of btrfs. Thankfully with the abuse of COW fixup, at least it won't crash the kernel. [FIX] Instead of immediately unlocking the extent and folios, we keep the extent and folios locked until either erroring out or the whole delalloc range finished. When the whole delalloc range finished without error, we just unlock the whole range with PAGE_SET_ORDERED (and PAGE_UNLOCK for !keep_locked cases) ---truncated---

    9402f36f (d4210000) ---[ end trace 0000000000000000 ]--- [CAUSE] That failure is mostly from
    cow_file_range(), where we can hit -ENOSPC. Although the -ENOSPC is already a bug related to our space
    reservation code, let's just focus on the error handling. For example, we have the following dirty range
    [0, 64K) of an inode, with 4K sector size and 4K page size: 0 16K 32K 48K 64K
    |///////////////////////////////////////| |#######################################| Where |///| means page
    are still dirty, and |###| means the extent io tree has EXTENT_DELALLOC flag. - Enter extent_writepage()
    for page 0 - Enter btrfs_run_delalloc_range() for range [0, 64K) - Enter cow_file_range() for range [0,
    64K) - Function btrfs_reserve_extent() only reserved one 16K extent So we created extent map and ordered
    extent for range [0, 16K) 0 16K 32K 48K 64K |////////|//////////////////////////////| |<- OE
    ->|##############################| And range [0, 16K) has its delalloc flag cleared. But since we haven't
    yet submit any bio, involved 4 pages are still dirty. - Function btrfs_reserve_extent() returns with
    -ENOSPC Now we have to run error cleanup, which will clear all EXTENT_DELALLOC* flags and clear the dirty
    flags for the remaining ranges: 0 16K 32K 48K 64K |////////| | | | | Note that range [0, 16K) still has
    its pages dirty. - Some time later, writeback is triggered again for the range [0, 16K) since the page
    range still has dirty flags. - btrfs_run_delalloc_range() will do nothing because there is no
    EXTENT_DELALLOC flag. - extent_writepage_io() finds page 0 has no ordered flag Which falls into the COW
    fixup path, triggering the BUG_ON(). Unfortunately this error handling bug dates back to the introduction
    of btrfs. Thankfully with the abuse of COW fixup, at least it won't crash the kernel. [FIX] Instead of
    immediately unlocking the extent and folios, we keep the extent and folios locked until either erroring
    out or the whole delalloc range finished. When the whole delalloc range finished without error, we just
    unlock the whole range with PAGE_SET_ORDERED (and PAGE_UNLOCK for !keep_locked cases) ---truncated---

  - btrfs: do proper folio cleanup when cow_file_range() failed [BUG] When testing with COW fixup marked as     BUG_ON() (this is involved with the new pin_user_pages*() change, which should not result new out-of-band     dirty pages), I hit a crash triggered by the BUG_ON() from hitting COW fixup path. This BUG_ON() happens     just after a failed btrfs_run_delalloc_range(): BTRFS error (device dm-2): failed to run delalloc range,     root 348 ino 405 folio 65536 submit_bitmap 6-15 start 90112 len 106496: -28 ------------[ cut here     ]------------ kernel BUG at fs/btrfs/extent_io.c:1444!

Although the -ENOSPC is already a bug related to our space     reservation code, let's just focus on the error handling. For example, we have the following dirty range     [0, 64K) of an inode, with 4K sector size and 4K page size: 0 16K 32K 48K 64K     |///////////////////////////////////////| |#######################################| Where |///| means page     are still dirty, and |###| means the extent io tree has EXTENT_DELALLOC flag. - Enter extent_writepage()     for page 0 - Enter btrfs_run_delalloc_range() for range [0, 64K) - Enter cow_file_range() for range [0,     64K) - Function btrfs_reserve_extent() only reserved one 16K extent So we created extent map and ordered     extent for range [0, 16K) 0 16K 32K 48K 64K |////////|//////////////////////////////| |<- OE
    ->|##############################| And range [0, 16K) has its delalloc flag cleared. But since we haven't     yet submit any bio, involved 4 pages are still dirty. - Function btrfs_reserve_extent() returns with
    -ENOSPC Now we have to run error cleanup, which will clear all EXTENT_DELALLOC* flags and clear the dirty     flags for the remaining ranges: 0 16K 32K 48K 64K |////////| | | | | Note that range [0, 16K) still has     its pages dirty. - Some time later, writeback is triggered again for the range [0, 16K) since the page     range still has dirty flags. - btrfs_run_delalloc_range() will do nothing because there is no     EXTENT_DELALLOC flag. - extent_writepage_io() finds page 0 has no ordered flag Which falls into the COW     fixup path, triggering the BUG_ON(). Unfortunately this error handling bug dates back to the introduction     of btrfs. Thankfully with the abuse of COW fixup, at least it won't crash the kernel. [FIX] Instead of     immediately unlocking the extent and folios, we keep the extent and folios locked until either erroring     out or the whole delalloc range finished. When the whole delalloc range finished without error, we just     unlock the whole range with PAGE_SET_ORDERED (and PAGE_UNLOCK for !keep_locked cases) ---truncated---     (CVE-2024-57976)

Note that Nessus relies on the presence of the package as reported by the vendor.
