  "title": "smb/client: fix stale page cache in insert/collapse range",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  smb/client: fix stale page cache in insert/collapse range  smb3_insert_range() and smb3_collapse_range() use truncate_pagecache_range() to invalidate the affected page cache. However, if off or old_eof is not page-aligned, the boundary pages are only partially zeroed and remain uptodate. As a result, the client may return stale data after a successful insert/collapse range operation.  For example, with 4K pages:      page 0          page 1          page 2     0------4K       4K------8K      8K------12K        ^                                ^     off=2K                       old_eof=10K  Page 1 is removed from the page cache, while the boundary pages are only partially zeroed. After COPYCHUNK moves the data on the server, these cached pages may still return stale data.  This can be reproduced on a CIFS mount:      bash -c \u0027             FILE=/mnt/scratch/repro              # Use a 6 KiB file so EOF is not page-aligned.             dd if=/dev/urandom of=/tmp/src bs=1K count=6 status=none              # Expected: a 4 KiB hole followed by the original data.             rm -f /tmp/expected             truncate -s 4K /tmp/expected             cat /tmp/src \u003E\u003E /tmp/expected              cp /tmp/src \u0022$FILE\u0022              # Prime the page cache before moving data on the server.             cat \u0022$FILE\u0022 \u003E /dev/null              fallocate --insert-range -o 0 -l 4K \u0022$FILE\u0022              if cmp -s /tmp/expected \u0022$FILE\u0022; then                     echo \u0022readback: OK\u0022             else                     echo \u0022readback: STALE DATA\u0022             fi     \u0027  Fix this by writing back dirty data and discarding the page cache from the start of the page containing off to EOF before moving data on the server.",
