## Description

In the Linux kernel, the following vulnerability has been resolved:  btrfs: subpage: keep TOWRITE tag until folio is cleaned  btrfs_subpage_set_writeback() calls folio_start_writeback() the first time a folio is written back, and it also clears the PAGECACHE_TAG_TOWRITE tag even if there are still dirty blocks in the folio. This can break ordering guarantees, such as those required by btrfs_wait_ordered_extents().  That ordering breakage leads to a real failure. For example, running generic/464 on a zoned setup will hit the following ASSERT. This happens because the broken ordering fails to flush existing dirty pages before the file size is truncated.    assertion failed: !list_empty(&ordered->list) :: 0, in fs/btrfs/zoned.c:1899   ------------[ cut here ]------------   kernel BUG at fs/btrfs/zoned.c:1899!

In zoned mode or for compressed writes, it locks several folios for delalloc and starts writing them out. Let's call the last locked folio folio X. Suppose the write range only partially covers folio X, leaving some pages dirty. Process A calls btrfs_subpage_set_writeback() when building a bio. This function call clears the TOWRITE tag of folio X, whose size = 8K and the block size = 4K. It is following state.     0     4K    8K    |/////|/////|  (flag: DIRTY, tag: DIRTY)    <-----> Process A will write this range.  Now suppose process B concurrently calls writepages() with WB_SYNC_ALL. It calls tag_pages_for_writeback() to tag dirty folios with PAGECACHE_TAG_TOWRITE. Since folio X is still dirty, it gets tagged. Then, B collects tagged folios using filemap_get_folios_tag() and must wait for folio X to be written before returning from writepages().     0     4K    8K    |/////|/////|  (flag: DIRTY, tag: DIRTY|TOWRITE)  However, between tagging and collecting, process A may call btrfs_subpage_set_writeback() and clear folio X's TOWRITE tag.    0     4K    8K    |     |/////|  (flag: DIRTY|WRITEBACK, tag: DIRTY)  As a result, process B won't see folio X in its batch, and returns without waiting for it. This breaks the WB_SYNC_ALL ordering requirement.  Fix this by using btrfs_subpage_set_writeback_keepwrite(), which retains the TOWRITE tag. We now manually clear the tag only after the folio becomes clean, via the xas operation.
